Tunnel Drill Bit

Tunnel Drill Bit

GREAT can customized bigger diameter Hole openers for tunneling , such as subway , gas pipeline construction.

Characteristics of tunnel engineering:

The whole project is buried underground, so engineering geology and hydrogeology conditions play an important and even decisive role in the success or failure of the tunnel construction.

Should not only be detailed geological survey and exploration in exploration stage, as accurately as possible to grasp the tunnel project within the scope of the rock properties, the strength of rock mass, complete degree, ground stress field, the stable ability, the condition of groundwater state, the harmful gas and geothermal data, and according to these raw materials, preliminary selected appropriate construction methods, determine the corresponding construction measures and form a complete set of construction machinery.

Moreover, due to the complexity of geological conditions and the limitations of exploration methods, it is still inevitable that unexpected conditions occur during construction.

Therefore, in the construction of the long tunnel, it is necessary to take some technical measures such as test guide pit (such as qinghan tunnel in Japan), horizontal advance drilling, acoustic detection and lead guide pit, so as to further investigate the geological conditions in front of the excavation and timely grasp the changes.

In order to modify the construction method and technical measures as soon as possible.

The highway tunnel is a building with a flat shape. Under normal circumstances, there are only two working faces, namely, the inlet and the outlet, compared with the bridge and line engineering.

The construction speed of the tunnel is slow and the construction period is long.

Therefore, best drill bit for granite rock is necessary to excavate additional auxiliary works such as vertical shaft, inclined shaft and horizontal hole to increase working face and speed up tunnel construction.

In addition, the tunnel section is small, the worksite is long and narrow, some construction procedures can only work in sequence, and some procedures can be along with the tunnel longitudinal development, parallel operation.

Therefore, the construction requirements to strengthen management, reasonable organization, avoid mutual interference.

The equipment inside the hole and the pipeline layout should be carefully considered and properly arranged.

Tunnel construction machinery shall be compact and durable.

The underground construction environment is poor, and may even worsen it during the construction, such as the harmful gas generated by blasting.

Effective measures must be taken to improve, such as artificial ventilation, lighting, dustproof, muffling sound, sound insulation, drainage, so that the construction site in accordance with health conditions, and have enough illumination, in order to ensure the health of construction personnel, improve labor productivity.

Most highway tunnels pass through mountains, so construction sites are generally located in remote mountains and narrow valleys, often far away from existing traffic lines, inconvenient transportation, and difficult supply. These are also one of the issues that should be considered when planning tunnel projects.

Highway tunnel is buried in the ground, once built, it is difficult to change, so in addition to careful planning and design in advance, the construction should be done without any future problems.

Of course, the tunnel project also has many advantages. For example, the construction can not be affected by the change of day and night, the change of seasons, the change of climate and other natural conditions.

Choosing GREAT made Hole opener for your high quality and safety works.

1. The underground jumbo needs to be ready for the following installation work:

(1) Installation site. Depending on the size of the trolley, it is necessary to leave the stacking and installation site, generally 20m x 20m;

(2) Sleepers and rails.

(3) Lifting equipment. When installing the gantry for most trolleys, it can be installed directly by the existing excavator or loader on the construction site. However, when installing the upper gantry and formwork, it must be installed with a crane of 16 tons or more;

(4) There are a total of 6-8 installation assistants. Generally, the trolley service is installed by the after-sales service personnel of the manufacturer;

(5) The welding machine and the gas cutting device are the connecting parts for processing the reinforcing parts during the transportation of the trolley;

(6) The board generally requires more than 5cm thick and is used for the mounting and operating platform.

2. How to determine the underground jumbo centerline?

When underground jumbo is positioned, the center line of the trolley must be determined first.  The way to determine the center line is simple, with a positioning cross at the top center. The intersection point is the midpoint of the trolley that the manufacturer has set up in the production of the trolley. By passing this point and drawing the vertical line of gravity, the center line of the trolley can be found.

3. How to measure the section size of the underground jumbo when the jacking cylinder is designed below?

When the jacking cylinder is designed below, it is not easy to measure the widest point of the trolley because the cylinders on both sides hinder the direct measurement of the measuring tool.  A horizontal line can be drawn on the trolley template, and the height of the two sides can be consistently matched by a tool such as a level gauge, and a rod (such as a thin thread steel) can be welded, and then the width of the section can be obtained by measuring the lead rod.

4. How to position the underground jumbo?

Before the lining work of the underground jumbo, the trolley must be positioned so that the profile size of the trolley conforms to the required size. After the trolley walks to the section to be lined, it is positioned by the following actions:

(1) Adjust the center line of the trolley by operating the translation cylinder of the hydraulic system to align it with the centerline of the tunnel;

(2) Operate the hydraulic system jacking cylinder to raise the trolley to the standard lining height, and then tighten the foundation jack, then review the height dimension;

(3) Operate the hydraulic system so that the lateral cylinder piston rod extends and reaches the standard lining section, and then manually pulls the lateral support screw to make it reach the lateral cylinder support position and tighten;

(4) After completing the above actions, the section size should be reviewed to prevent error

Vibration Absorber and Vibration Isolator

Difference and concept between shock absorber and vibration isolator

A shock absorber is the main means to prevent vibration hazards in engineering. The wire rope shock absorber can be divided into active shock absorber and passive shock absorber. The active vibration damper is designed to eliminate the vibration source or reduce the energy or frequency of the vibration source. It is widely used in precision instruments, aerospace equipment, large steam turbine generator units and high-speed rotating machinery, but it is expensive and less used in common construction machinery. Passive shock absorbers include vibration isolators and absorbers. The wire rope vibration isolators can be divided into active isolator and passive isolator.

In order to prevent or limit the harm and influence caused by vibration, various measures are adopted in modern engineering, which is summarized as follows:

  1. Reduce or eliminate the vibration source (active shock absorber)

This is a positive fundamental measure. If the vibration is caused by the eccentricity of the rotating parts, the unbalanced centrifugal inertia force can be reduced by improving the dynamic balance accuracy. For reciprocating machinery such as air compressor, attention should also be paid to the balance of inertia force.

  1. Keep away from a vibration source (passive vibration isolator)

This is a negative protective measure. For example, precision instruments or equipment should be as far away as possible from factories or workshops with large power machinery, pressure processing machinery and vibration machinery, as well as railways and highways with busy transportation.

  1. Improve the anti-vibration ability of the machine itself (active shock absorber)

The commonly used index to measure the anti-vibration ability of the machine structure is the dynamic stiffness, which is equal to the dynamic force required by the unit amplitude of the machine structure. The larger the dynamic stiffness, the smaller the vibration of the machine structure under the dynamic force.

  1. Avoid resonance area

Change the natural frequency of the system (active damper) or the working speed of the machine (passive damper) as much as possible according to the actual situation, so that the machine does not work in the resonance area.

  1. Increase damping appropriately (damping and vibration absorption)

Damping absorbs the vibration energy of the system and makes the amplitude of the free vibration attenuate rapidly. It can restrain the amplitude of the forced vibration, especially in the resonance region.

  1. Dynamic vibration absorption (passive vibration absorption)

For measuring or monitoring instruments on some equipment, the method of installing dynamic vibration absorber under the instrument can stabilize the pointer of the instrument and improve the measurement accuracy.

  1. Take wire rope vibration dampersmeasures

Using elastic vibration isolator to isolate the vibrating machine (vibration source) from the foundation, so as to reduce the vibration source to affect the surrounding equipment through the foundation, which is the active vibration isolator or active vibration isolator; or isolating the precision equipment to be protected from the impact of the surrounding vibration source, which is the passive vibration isolator.

Alcohols (Organic Compounds

Alcohols, a large group of organic compounds, are compounds in which hydrogen atoms in side chains of aliphatic hydrocarbons, alicyclic hydrocarbons or aromatic hydrocarbons are replaced by hydroxyl groups. In general, alcohols and hydroxyl groups are linked to a saturated, SP3 hybrid carbon atom. If hydroxyl group is linked to benzene ring, it is phenol; if hydroxyl group is linked to SP2 hybrid olefin carbon, it is enol. The properties of phenols and enols are quite different from general alcohols.

 

In industrial production, most of the simple saturated monoalcohols, except methanol, are produced from olefins. However, before the rise of the petroleum industry, some alcohols were produced by fermentation.

 

The following are several important alcohols:

 

Methanol (lignol) is synthesized from syngas (CO and H ramming) in the presence of heating, pressure and catalyst.

 

Ethanol, commonly known as alcohol, is one of the most widely used alcohols.

 

Glycol, the simplest and most important binary alcohol, is a sweet, viscous, colorless liquid.

 

Glycerol, commonly known as glycerol, is a colorless and sweet viscous liquid, which can be mixed with water, is insoluble in organic solvents and has strong water absorption.

Several Types of Microbial Culture Media

 8466719495?profile=original

 

Different types of bacterial culture media:

  1. According to the composition, bacterial culture media can be divided into three types: synthetic medium, natural medium and semi synthetic medium.

(1) Synthetic medium. The components of the synthetic medium are all known chemicals. The chemical composition of this medium is clear, the composition is accurate, the repeatability is strong, but the price is expensive, and the growth of microorganisms in this medium is slow. For example, Gao's No.1 synthetic medium and Czapek medium belongs to this type.

(2) Natural medium. It is made of natural substances, such as steamed potato and common beef soup. The former is used to cultivate mold and the latter is used to cultivate bacteria. The chemical composition of this kind of culture medium is very unsteady and difficult to determine, but it is easy to prepare, rich in nutrition and good in culture effect, so it is often used.

(3) Semisynthetic medium. On the basis of natural organic matter, some inorganic salts with known components are added properly, or some natural components are added on the basis of synthetic medium. This kind of medium can more effectively meet the needs of microorganisms for nutrients.

  1. According to the physical state, the bacterial culture media can be divided into three types: solid medium, liquid medium and semi-solid medium.

(1) Solid medium. Coagulant is added to the culture medium, including agar, gelatin, silica gel, etc. The solid medium is often used in the separation, identification, counting and preservation of microorganisms. It is used for microorganism separation, identification and counting. As shown in the figure, microorganisms are separated into colonies and lichens.

(2) Semi-solid medium. A small amount of coagulant is added to the liquid medium to form a semi-solid state. It can be used to observe the movement of bacteria, identify bacteria and determine the titer of phage. It is used to observe the movement characteristics of microorganisms.

(3) Liquid medium. No coagulant was added to the liquid medium. The composition of the medium is even, and the microorganism can fully contact and use the nutrients in the medium, which is suitable for physiological research. Because of the high fermentation rate and convenient operation, it is also commonly used in the fermentation industry. It is also sed to observe the growth of microorganisms.

  1. According to the types of microorganisms, bacterial culture media can be divided into four types: bacterial culture media, actinomycete culture media, yeast culture media and mold culture media.

(1) The commonly used bacterial culture media are nutrient broth and nutrient agar.

(2) The commonly used actinomycete culture media is gauze No.1 .

(3) The commonly used yeast culture medium includes potato sucrose culture medium and malt juice culture medium.

(4) The commonly used mold culture media are potato sucrose culture medium, bean sprout juice sucrose (or glucose, glucose is more expensive) agar culture medium and chasser culture medium.

  1.  According to their use, bacterial culture medium can be divided into: basic medium, identification medium, selective medium and enrichment medium.

(1) Basic medium. It is a medium containing the basic nutrients for the growth and reproduction of general microorganisms.

(2) Enrichment medium. It is a medium made by adding blood, serum, animal and plant tissue extracts. It is used to cultivate some microorganisms with strict requirements.

(3) Selective medium. It is to add special nutrients or chemicals into the ordinary culture medium to inhibit the growth of unnecessary microorganisms, which is conducive to the growth of required microorganisms. It is used to separate a certain or a certain kind of microorganism from a mixed microbial population.

(4) Identification medium. It is to add some reagents or chemicals into the culture medium, so that some changes will occur after culture, so as to distinguish different types of microorganisms.

The groundnut oil pressing machine(groundnut oil press) is generally divided into vertical oil top type oil press and screw oil press. Peanut is crushed, selected (to separate peanut from the shell), stir-fried to 6-8 maturity and then physical pressed by oil press. The pressed product of groundnut oil press is peanut oil and peanut residue. Peanut residue is edible. Groundnut oil press can ensure the oil yield of groundnut oil press in four steps. Let's share with you.

 

  1. Harvest at the right time. The peanuts used for seed retention are harvested earlier than those used for oil extraction. For the peanut harvested at the right time, the inner membrane of the shell is white and the seed viability is strong; the top of the plant has stopped growing, the upper leaves are yellow, the middle and lower leaves fall off, the stem is yellow and there are irregular long black spots. At this time, most of the pods planed out have obvious reticulation and full seed kernel. Generally, the early varieties and barren plots are collected first, the late varieties and the plots with sufficient water and fertilizer are collected later. The germination rate of pods harvested in wet soil was higher than that harvested in dry soil.

 

  1. Select and keep seeds. When picking the fruit, you should remove the miscellaneous and inferior, the dead plant pods, the sprouted pods, the seeded pods and the tender ones. Most of these fruits are pitiful and dead embryo fruits, which can neither sprout nor mildew easily and can not be used for seed.

 

  1. Sunseed. The moisture content of newly harvested peanut fruit is generally 45-50%, which is too high. To ensure the quality and safe storage of peanut seeds, after harvest, the seedlings should be turned upside down and dried in the field, and then transported to the solar farm to pick pods two days later. In the process of seed drying, rain and heat should be prevented. Hot seeds can't germinate. If it rains, don't pile up pods or put them into baskets. This will make the seeds hot. The right way is to spread peanuts thin on the interior of the house to dry so that the water will slowly dissipate. When drying seeds, the field should be turned frequently. When there is a noise in shaking the pods and the teeth bite the pods, turn them over for another day, peel off the shells and bite the nuts with the teeth. When the seed coat is easily removed by hand rubbing, the seeds can be put into storage. At this time, the moisture content of the seeds is generally about 10%.

 

  1. Storage. The best way to store peanuts is to use a clean tank. Put the cylinder on the ground and pad bricks under the cylinder before planting. First, sprinkle a layer of hay ash in the jar, then pour in the newly dried pods. After 6 hours, sprinkle a layer of hay ash about 10 cm thick on the peanut seeds, and then seal the cylinder head.

 

The groundnut oil expeller machine can be widely used in rural oil processing and on-site processing and production of urban grain and oil market and can complete a working cycle in an hour. Once squeezed, consumers can get the oil products quickly, without further processing and filtering, they can eat it and there is no adulteration in the processed oil products, with high reliability.

Ordinary culture medium: a kind of artificial preparation, suitable for the growth and reproduction of microorganisms or the production of metabolites, or for other mixed nutrients.

Characteristics: any culture medium should have the six nutrient elements needed by microorganisms and should be proportioned appropriately. Once prepared, it must be sterilized immediately.

Uses: promote the growth of microorganisms; accumulate metabolites; isolate microbial species; identify microbial species; count microbial cells; preserve microbial species; prepare microbial products.

General configuration steps of ordinary culture medium

  1. Mix ingredients

Formula conversion → add a small amount of water (distilled water, natural water) into the container → weigh all kinds of drugs according to the formula (add in order) → add enough water (one medicine and one spoon, and immediately cover the bottle after taking the medicine).

  1. dissolution

Starch dissolving: a small amount of cold water is mixed into paste

Heat and dissolve, especially the medium with agar must be boiled. The melting temperature of agar is 95-97 ℃  and it needs to be stirred while heating to prevent burning.

  1. Adjust PH

Adjust the medium to the required value with 1n hydrochloric acid or 1n NaOH.

  1. filtration

Filter paper or cotton. (sometimes it can be omitted)

  1. sub package

Generally, the culture medium is placed in a triangular flask or test tube for sterilization.

  1. Packing

After repacking, plug the cotton plug, and wrap the cotton plug with kraft paper to prevent water from entering and wetting the cotton plug during sterilization.

  1. sterilization

Carry out high-pressure steam sterilization according to the temperature and pressure required on the formula. If the sterilization temperature is too high, the nutrients will be destroyed and cultured

The sugar and amino acid in the medium will darken the color of the medium.

  1. pendulum

After sterilization, the tubes that need to be placed in an inclined plane should be placed in an inclined position while it is hot, so that they will solidify into an inclined plane, accounting for about one second of the tube length.

  1. storage

The medium can be used without pollution after being placed at 30 ℃ for one day. It is generally wrapped with kraft paper and stored in 2-8 ℃ refrigerator for standby.

Configuration principle

  1. Choose the right nutrients

Generally speaking, all microbial growth and reproduction need nutrient culture medium containing carbon source, nitrogen source, inorganic salt, growth factor, water and energy. However, due to the complex types of microbial nutrition, different microorganisms have different needs for nutrients. Therefore, first of all, we need to prepare targeted culture medium according to the nutritional needs of different microorganisms.

  1. appropriate concentration and proportion of nutrients

When the concentration of nutrients in the medium is appropriate, the growth of microorganisms can be good. When the concentration of nutrients is too low, it can not meet the needs of normal growth of microorganisms. When the concentration is too high, it may inhibit the growth of microorganisms.

  1. PH control

The pH of the medium must be controlled within a certain range to meet the growth and reproduction of different types of microorganisms or the production of metabolites.

  1. redox potential

Different types of microbial growth have different requirements on redox potential (f). Generally, aerobic microorganisms can grow normally when the F value is above + 0.1V, and it is suitable to grow normally when the F value is + 0.3V + 0.4V. Anaerobic microorganisms can only grow when the F value is below + 0.1V, facultative anaerobic microorganisms can breathe when the F value is above + 0.1V, and ferment when the F value is below + 0.1V.

  1. Selection of raw materials

In the preparation of culture medium, we should try to use cheap and easy material to obtain raw materials as the components of culture medium, especially in the fermentation industry, and the amount of culture medium is very large, and the use of low-cost raw materials reflects its economic value.

  1. Sterilization treatment

In order to obtain pure culture of microorganism, contamination of mixed bacteria must be avoided, so the equipment and workplace should be disinfected and sterilized.

PUNCHING

Punching is a forming process that uses a punch press to force a tool, called a punch, through the workpiece to create a hole via shearing. Punching is applicable to a wide variety of materials that come in sheet form, including sheet metal, paper, vulcanized fiber and some forms of a plastic sheet. The punch often passes through the work into a die. A scrap slug from the hole is deposited into the die in the process. Depending on the material being punched this slug may be recycled and reused or discarded. Punch tooling (punch and die) is often made of hardened steel or tungsten carbide.

Very often the finished product requires various types of holes, differing by position and shape. The possibility of making these holes inside the roll forming line makes it possible to obtain the product without the need for additional processing steps, with better quality and reduced cycle time and semi-processed products warehouse. The workpiece is often in the form of a sheet or roll. Materials for the workpiece can vary, commonly being metals and plastics. The punch and die themselves can have a variety of shapes to create an array of different shaped holes in the workpiece. Multiple punches may be used together to create a part in one step.

Punching machine china has many advantages:

The dimensional accuracy is guaranteed by the mold, so the processed parts have stable quality and good consistency, and have the characteristics of “ exactly the same”.

Stamping can obtain parts that are thin, light in weight, good in rigidity, high in surface quality, and complex in shape that cannot be manufactured by other processing methods;

High material utilization rate, which is less and no chip processing;

High efficiency, convenient operation, and the required technical level of workers is not high;

The mold has a long service life and low production cost.

LASER/PLASMA CUTTING AND WELDING

Online cutting process analysis

The cross-section of the plasma laser cutter is not only closed but also complicated. The plasma profile closed section is composed of a vertical surface, a horizontal surface and a curved surface, and the material is a galvanized steel sheet of 1.25 mm. It is required to ensure not only the quality of the section but also the galvanized layer and the speed of the production line. This brings a lot of trouble to the mold design. If the conventional cutting die is used for the overall cutting, it will not be cut off, and the product requirements cannot be met. According to the characteristics of the parts, a deep analysis is made, and it is decided to reserve a cutting amount of 6.8 mm before cold forming. Because the shape of the part is very special, the edge of the punch must be shaped, not only to cut the curved surface, the horizontal surface, and the vertical surface, but also to have no sag and scratches. According to the process requirements, in order to prevent the sag and ensure the convexity Intensity, it is decided that the process hole should be pre-punched in the middle of the part and at the corner, and the pre-punching hole must be punched out before forming, that is, before the cold bending, a process is added - pre-punching, so a pre-punch is designed. Hole mold. That is, two sets of molds are required to cut the workpiece: a set of pre-punching dies and a set of cutting dies.

Pre-punching the design

  1. Position determination of mutual pre-punching

From pre-punching to cutting, there is a forming process in the middle, so that the position of the pre-punching is more complicated. Not only to ensure the quality of the cut surface, but also to choose the right position to improve the strength of the die of the cutting die, and also to ensure that the cold forming of the cutting die is not affected, and according to the requirements of the stamping process, the hole of the punching part The distance between the holes and between the holes and the edges should not be too small to correct the position of the holes and repeatedly simulate through the computer. The hole in the middle portion is to ensure that the intermediate portion of the punch is not too long and too sharp, and the formed chips are easily discharged when the top of the workpiece is punched. The hole at the corner is to ensure that there will be no sag at the time of cutting, and at the same time, it will not produce chips that are difficult to discharge.

  1. Unfolding of the workpiece

Directly use the Pro/E expansion command to expand the part to get the expanded view. Expand the Expand Create Sheet Metal Unbend Regular by expanding the command, select a datum plane or edge (unmoved or edge) when unfolding, then select the Unbcnd All command, and then click OK.

  1. Structural design and working process analysis of pre-punching die

①Pre-punching die structure design

According to the unfolding diagram and precision requirements, the diagonal guide column formwork is selected, and the formal form is adopted, the punch is on the upper side, and the concave mold is on the lower side. For economical processing and easy maintenance and replacement, the male and female molds are in a block-like structure, so that the insert can be replaced without removing the entire mold. After the two punches and the punch fixing plate are fixed, they are directly fixed on the upper mold base 7 by screws together with the punch pad, and the two concave molds are symmetrically set in the lower mold base.

In order to prevent the sticking of the scrap, the unloading rubber is specially designed on the punch, and after the scrap is punched off, the scrap is smoothly separated from the convex and concave molds under the elastic force of the rubber. In order to reduce the labor, the edge portion is made 1. S0 slope. In addition, because it is an online automatic production, the strip is automatically fed, so a fixed discharge plate is adopted, so that the discharge plate not only functions as a discharge plate but also functions as a guide plate, and the fixed discharge plate has a discharge force. Large, simple structure. Single features.

②Analysis of the working process of pre-punching die

In the working process, the plate guides the guide plate (the guide plate and the discharge plate 3 are the same plates), and the feeding process is automatic feeding, and the punching position is determined by the photoelectric switch. The plate is taken to the proper position. Under the action of the hydraulic machine, the upper mold base drives the punch downward, and the punch starts to work. Under the joint action of the convex and concave molds, the punching is completed. Under the elastic force of the rubber, the waste is smoothly leaked from the leakage hole, and the punch is lifted up, and one stroke is completed.

In order to improve the softness and handle of tissues, the use of softeners in pulp is a common method in the paper-making industry. Although softeners can improve the softness of paper towels, the range of improvement is very limited. It has been reported that a certain amount of paper softener was added to the pulp, and the softness of the paper decreased by about 20%, but it still belongs to the hard paper. Therefore, it is urgent to develop a method that does not depend on paper softener to produce some paper with better softness.

 

Through experiments, the application of alcohol compounds in tissues and their adding methods can greatly improve the softness of tissues, and it can improve the moisture content of tissues at the same time. When contacting with human skin, it will not plunder skin moisture, and frequent wiping will not easily produce peeling phenomenon. Because of its high softness, it is especially suitable for infants.

Those Things About the Spectrophotometer

Spectrophotometer, also known as spectrometer, is a commonly used analytical instrument for qualitative and quantitative analysis of the substance by measuring the absorbance of light at a specific wavelength or a certain wavelength range.

 

Spectrophotometer comes in many varieties and uses. Visible spectrophotometers are mainly used in chemical analysis such as metallurgy, medicine, food industry, medicine, health, chemical, school, biochemistry, petrochemical, quality control, environmental protection and scientific research laboratories. It is a single-beam spectrophotometer that measures the absorbance of visible light (400-760 nm) of a substance to be tested and qualitatively and quantitatively analyzes it.

 

The atom first absorbs the spectrophotometer source and then emits the measured characteristic spectrum radiation. It is absorbed by the ground state atoms of the element to be tested in the sample vapor after passing through the atomizer. The content of the element to be measured is determined by measuring the magnitude of absorption of the characteristic radiation. It is one of the conventional instruments for the analysis laboratory of production, education and scientific research units.

 

The UV-Vis spectrophotometer is used to measure the absorbance of the sample to visible or ultraviolet light (200-760 nm) and to qualitatively and quantitatively analyze it. It has been widely used in the fields of drug analysis, drug testing, sanitary and epidemic prevention foods, environmental testing, chemical engineering, scientific research, etc. It is an indispensable instrument for production, scientific research and teaching.

How to choose a couture dresses online?

 

For the wedding, probably every girl has a variety of expectations and fantasies. There are also many expectations for wedding dresses and bridesmaids. On the wedding day, there are all sorts of trivial matters and unexpected situations that make the bride unprepared, so be sure to ask the bridesmaid to help you with this. As the right hand for the bride on the wedding day, the bridesmaid also needs to be dressed up.

 

The bridesmaid dress needs to be consistent with the wedding color, the design is simple, certainly not better than the bride's wedding dress. Most of the skirts are over the knees, elegant and dignified, and the length of the skirt that is less than the knee will be less formal. Bridesmaid dresses should be low-key, too exposed to easily overshadow the bride's limelight.

 

So what color should the bridesmaid dress choose? This also needs to be coordinated with the theme of the wedding dress and wedding, and also consider the skin color of the bridesmaid.

 

  1. Light color

 

Most brides choose white wedding dresses, so light bridesmaid dresses are also the most common. The beige dress can brighten the complexion and is perfect for Asian yellow skin. The long skirt of the mopping floor is romantic and dreamy.

 

The pale pink dress is lively and playful, which can bring out the sweet temperament of the bridesmaid. It is especially good to take pictures in the bright sunshine.

 

  1. Saturated color system

 

A dress with a high degree of saturation is more solemn and will be more mature and more atmospheric than a light-colored dress. Is the pink dress with high saturation appearing very formal?

 

On the choice of the style, color of the bridesmaid dress, you need to book in advance. Because the bridesmaid dress is the same as the wedding dress, it is tailor-made. After getting the dress, you should try it on the bridesmaid. If there is no suitable place, there is still time to make changes.
