Here offer pieces of information about how to use quick dry sealant or fast drying silicone glue.
1.Use: A single group of silicone glass glue can be used immediately. It is easy to type it from the bottle with a glue gun, and a spatula or wood chip can be used to trim the surface.
2.Adhesion time: the curing process of silicone rubber is developed from the surface to the inside. The drying time and curing time of different characteristics of silica gel are different. So if you want to fix the surface you have to do it before the glass gel sheet is dry (acid glue, neutral and transparent glue should be in 5-10 minutes, neutral color glue should be in 30 minutes generally). If the color paper is used to cover a certain place, after coating, it must be removed before the skin is formed.
3.Curing time: the curing time of glass glue increases as the adhesive thickness increases. For example, the acid glass glue of 12mm thickness may take 3-4 days to solidify. But within about 24 hours, the outer layer of 3mm has been solidified. When glued to glass, metal or most wood, it has an anti-stripping strength of 20 pounds per inch at room temperature after 72 hours. If the use of glass glue is partially or completely sealed, the solidification time is determined by the closeness of the seal. In a place of absolute closeness, it is possible to remain uncured forever. If the temperature is raised, the glass will soften. The gap between metal and metal bonding should not exceed 25mm. In all kinds of bonding situations, including airtight conditions, the adhesion effect should be thoroughly checked before the equipment is used. In the curing process, acid glass glue will produce a smell due to the volatilization of acetic acid, which will disappear in the curing process. There will be no smell after curing.
4.Adhesion: A. Wipe the surface of the metal and plastic completely, remove the oil, and then wash the whole surface with acetone except for the plastic. If it is rubber surface, apply sandpaper and rub it with acetone. Please observe the precautions when using acetone. B. Apply the glass glue evenly on the surface of the prepared object. If the two surfaces are glued together, place one side properly first and press the other side to squeeze out the air, but be careful not to extrude the glass. C. place the bonding device at room temperature and wait for the glass to solidify.
5.Seal: the silicone glass sealant also can be used for sealing purposes according to the above steps. Squeeze the glass glue into the joint or the seam so that the glass glue is in full contact with the surface.
6.Cleaning: before curing, the glass glue can be erased with a cloth or paper towel. After curing, it should be cleaned with a scraper or xylene, acetone and other solvents.

The key of how passive house performs lays on well designed ventilating which can not only filtrating too much moisture in the air and peculiar smell but pollen and dust, providing clean and fresh air for rooms. If you open the window for ventilation, a lot of quantity of heat will be lost, and the loss is more than the total quantity of heat that a passive house needs. Under most climate conditions, passive house wants certain heating but the quantities are small, which can be realized by ventilating. Through heating coil to warm up fresh air, the heating needs left can be met, and that is the concept of the fresh air system of passive house for supplying heating.
Principle of the ventilation of passive house
The basic principle of the ventilation of passive house: the muddy air in kitchen and bathroom is extracted (air exhaust) and the fresh air will be delivered in to where people live (air supply), and automatic air exhaust can be realized in hallway. For example, the standard of fresh air is 20m2/h for one person and per capital living space is 30m so that the quantity of air supply should be 1m/2(m?h). the highest temperature is limited as 50 ℃ and the corresponding heat load is 10W/m* in order to avoid the peculiar smell produced by excessive temperature causing the dust to be burned, meeting the requirement of heat supply.
The functions of ventilating
Ventilating, able to recycle the heat efficiently, emphasizes its own main functions: it can change the indoor air, which can control the air humidity in case of mildewing; it can stop the accumulation of pollutants and it can remove the peculiar smell. In addition, there are additional functions: it can regulate the indoor air and clean the air ( acts as filter) to eliminate PM2.5; it can work as humidifying and dehumidification. Passive house applies the ventilating recycling the heat efficiently, lowering the heat loss, increasing the temperature of fresh air and enhancing the degree of comfort indoors. Meanwhile, the ventilating of passive house regulates the humidity indoors ( the optimal range is with relative humidity of 35%-55%), over or lower will do harm to health, especially the skin and respiratory system. If the temperature is too high, it will go mouldy; if the the temperature of internal surface is lower than 12.6℃, it will be liable to mildew; instead, the temperature of internal surface is lower than 9.6℃, condensation will happen. Too low temperature will possibly damage the floor or musical instrument.
Thenow will strive to offer you hrv dehumidifier with good quality.
Here offer pieces of Information On Chemical Composition Of Silica Gel.
Silica gel alias: Silicic acid gel. It is a highly active adsorbent material and an amorphous material. The main component of silica gel is silica, which is chemically stable and does not burn. It has an open porous structure with strong adsorption and can absorb a variety of materials. When dilute sulfuric acid (or hydrochloric acid) is added to the aqueous solution of water glass, it will become hydrous silicic acid gel and become solid. The dissolved electrolyte Na+ and SO4 2-(Cl-) ions are removed by water washing. Silica gel can be obtained after drying.
Generally speaking, silica gel can be divided into organic silica gel and inorganic silica gel according to its properties and components.
Inorganic silica gel is a kind of highly active adsorption material, which is usually prepared by the reaction of sodium silicate and sulfuric acid and a series of post-treatment processes such as aging and submerge in acid. Silica gel is an amorphous substance. Its chemical formula is mSiO2. nH2O. It is insoluble in water and any solvent, non-toxic, odorless, stable in chemical properties, and does not react with any substances except strong alkali and hydrofluoric acid. Different types of silica gel have different micropore structure due to different manufacturing methods.
The chemical composition and physical structure of silica gel determine that it has many other characteristics which are difficult to be replaced by other similar materials: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc. It is used by families as desiccant, humidity regulator, deodorant, etc., by industry as oil hydrocarbon decolorizing agent, catalyst carrier, variable pressure adsorbent, etc., and by fine chemical industry as separation purifier, beer stabilizer, paint thickener, toothpaste friction agent, polish remover, etc.
Organic silica gel is an organosilicon compound that contains Si-C bonds, and at least one organic base is directly connected to the silicon atom. Traditionally, those compounds that connect the organic base to the silicon atom via oxygen, sulfur, nitrogen, etc., are also considered as organosilicon compounds. Moulded silica gel is a little more complex with irregular shapes, including silica gel bowl, silica gel ice lattice, silica gel cake mold and so on.
After knowing information above,you may have a deeper understangding of silica gel composition and silica gel chemical formula.

Automated assembly refers to the assembly of products through the use of automated machinery or assembly robots and systems. Only a small part of the work is controlled by people. In most cases, automation is often used to produce a standardized product assembly line for a series of specific actions or activities. Automated assembly is an important part of many technology companies and medical research plants.
Today, automation components in many factories are used to create components and then assemble a variety of products, from the food industry to the electronics industry. Workers only need on-site supervision to ensure that the assembly line process can be maintained and their ability to produce thousands of high-quality products can be maximized in the shortest possible time.
Medical research facilities and food processing factories often use automated assembly processes in areas where human contact may lead to danger or product contamination. Manipulators or robotic equipment are used to deal with the sealed environment in the above product systems to minimize this risk.
Large manufacturing companies use larger automated assembly equipment, including large-scale products such as automobiles that use heavy robotic equipment. In these environments, except that only a few workers operate in the central control center, the other processes are to assemble vehicles independently using assembly systems. Although this form of manufacturing looks more like a replacement for manual work, it reduces casualties and human failures.
In recent years, with the prosperity of the domestic electronic industry, the industry of our automated assembly machine has also taken advantage of the rising trend. At the same time, many manufacturers are gradually carrying out automation reform, replacing manual labor with machines, so many enterprises are rushing to introduce automation equipment, but its main equipment is automated assembly machine.
Features of the automated assembly machine:
Firstly, the automated assembly machine saves the cost to the enterprise. Because it can operate efficiently without human being, as long as one person feeds, it can be the efficiency of many people and save a lot of labor cost effectively.
Secondly, the automated assembly machine has good versatility and can store many sets of programs. As long as the customer changes the product size, the product program can be changed.
Thirdly, when designing, we have designed more product procedures, so it is convenient to change the products when making later production. By simply replacing the fixture, the production can be realized by simple programming, which is very convenient for enterprises to produce.
Fourthly, we all adopt the imported track to effectively ensure the stability of the machine and eliminate the adverse effects caused by human factors. The imported components also effectively ensure the stability of the machine.
Fifthly, with efficiency and convenience, an automated assembly machine can save about 5 people.

Lubricant is an indispensable additive in PVC processing. For lubricants, the commonly referred function in industry's can be summarized in two points, they are: it reduces the friction pre-melting particles of polyvinyl chloride and the macromolecules in the polyvinyl chloride melt. It is actually the most typical summary of the two aspects of lubricant action (internal and external lubrication). Then, we will discuss and analyze the internal and external lubrication of PVC lubricant from the technical level for you.
In terms of PVC, the internal lubrication of the lubricant and the plasticizer can be regarded as the same kind of material, playing the role of plasticizing or softening. The difference is that the polarity of the lubricant is lower and the carbon chain is longer. Therefore, compared with plasticizers, lubricants and PVC are less compatible. Lubricants are incompatibly (and moderately compatible) with polyvinyl chloride, so only a small number of lubricant molecules can pass through the chains of the polymer like plasticizers, weakening their mutual attraction. When the polymer is deformed, the chains can slip and rotate more easily without lowering the glass temperature of the polymer too much.
External lubrication refers to the interface lubrication mechanism. The lubricant is attached on the surface of the molten resin or on the surface of the processing machine or mold, forming a layer of lubricant molecules. lubrication interface which is formed by the existence of molecular layer of lubricant, reduced the friction between the resin and the processing machinery as as result. The viscosity of the sliding interface film and its lubrication efficiency depend on the melting point and processing temperature of the lubricant. In general, lubricants with long molecular carbon chains play a better role of lubrication because they keep the two friction surfaces away from each other.
"Small dosage, large effect" . This sentence is an appropriate description of PVC lubricant. The function of PVC lubricant is no less than stabilizer in the role of PVC processing. Generally, its use needs to follow strict principles, such as slippery balance inside and outside, right amount moderate etc. If the degree of significance of PVC lubricant is not enough, and we do not follow principles that should be observed, what will happen if PVC lubricant is not used well?
Too much external lubrication. The extrusion speed is fast, the material is easy to produce, and the plasticization is not good. Too much internal lubrication. There will be large extrusion and poor plasticization of materials. Poor initial lubrication will make the extrusion torque larger. Insufficient lubrication in the later stage will lead to insufficient lubrication in screw homogenization section, compression section and die section, violent shear of materials, which will affect the surface quality and internal performance of extruded products. More seriously, it even causes decomposition.
Lubricant is incompatible with PVC resin. Too much lubricant will have a bad effect on PVC blending system. Lubrication of internal and external balance, is balance within a certain limit because the mixing system of lubricant and PVC has bad effect. In the actual production, there are many processing problems related to thermal stability and many defects of the products. The root cause may be the excessive amount of lubricant.
High melt point - melting point of paraffin wax in celsius is very suitable for making cylindrical candles, hand-dipped fine candles, moulded candles, moulded or carved gift candles. High melt wax is very hard and cannot retain its fragrance. Its melting point is 145 degrees Fahrenheit or 63 degrees Celsius. This kind of wax is needed to make all kinds of waxes mentioned above so that the candle will not sink itself when it is cooled. If this high melt wax is used to make candles, additives are needed.
Medium Melting Point - This kind of wax is usually used to make prayer candles and sometimes container candles. Its melting point is 127-145 degrees Fahrenheit or 53-63 degrees Celsius. This wax feels harder than low melting point wax, but it keeps its shape better. This wax has good fragrance retention, but additives are needed. This type of wax is massive and needs to be cut into small pieces to melt.
Low Melting Point - This type of wax melts at 127 degrees Fahrenheit or 53 degrees Celsius. Soft wax is an ideal material for making container candles and has the characteristics of lasting fragrance retention. Soft wax has strong flexibility and does not need additives until the candle burns out. Softer paraffin have many advantages, but they are difficult to process and emit more soot than other waxes.
Once you decide on the type of candle you want to make, you can choose the most suitable paraffin. Wherever you buy paraffin, you must know the melting point of the purchased paraffin, so that the gift candles will look good. When you buy, you need to have detailed instructions on the use of these waxes.
Concrete mixer truck is a special truck used to transport concrete for construction; it is often referred to as a snail car because of its shape. A cylindrical mixer drum is mounted on this type of truck to carry the mixed concrete. The mixing drum is always rotated during transportation to ensure that the concrete being conveyed does not solidify. After the concrete is transported, the inside of the mixing drum is usually washed with water to prevent the hardened concrete from occupying space and making the volume of the mixing drum less and less.
Structural principle of new concrete mixer truck: Concrete mixer truck consists of special equipment for automobile chassis and concrete mixing and transportation. The chassis of concrete mixer trucks produced in China mostly adopts the second-class universal chassis provided by the whole vehicle manufacturer. Its special mechanism mainly includes power take-off, front and rear brackets of the mixing drum, reducer, hydraulic system, mixing drum, operating mechanism, cleaning system and so on.
The working principle is that the power of the automobile chassis is taken out by the force taking device, and the variable pump of the hydraulic system is driven, the mechanical energy is converted into the hydraulic energy and transmitted to the quantitative motor, and the motor drives the speed reducer, and the stirring device drives the stirring device to carry out the concrete. Stir. Another type of mixer truck produced by Yantai Shenglida adopts a patent of the rotary seal, which can completely close the mixer drum and the inlet and outlet, and specifically solve the water evaporation and mortar stratification of traditional products. The series of problems such as dredging and driving safety has greatly improved the quality of concrete and building safety, and the effective volume of the mixing drum has increased to over 80%. The comprehensive performance of the whole vehicle has reached a new height. The fully enclosed mixer truck has Started to serve the Qingyan Weirong high-speed rail and high-quality construction projects.
The concrete mixer truck is used as a transportation vehicle. In terms of maintenance and repair, the maintenance and repair system of “regular inspection, mandatory maintenance, and condition-based repair” must be carried out in accordance with the regulations of the Ministry of Communications No. 13 of 1990. Under this premise, combined with the actual situation of the concrete mixer truck, maintenance and repair should be.
(1) Degreasing
Lipase enzymes used in leather industry has achieved good results in degreasing of crepe, fur, leather, gelatin, and the like. Candida lipolytica lipase can reduce the oil content of the raw material of the spinning material from 10% to 0.5%, to meet the spinning requirements, and does not affect the fiber strength. Lipase can also remove fat between leather collagen fibers and degrease for fur. It not only has the advantage of not affecting the thickness and fastness of the leather, it can also make the fur product full, soft and elastic. After lipase treatment, the small droplets in the gelatin solution can be removed, and the oil stains on the instrument rag and the optical components can be removed to improve the quality and cleanliness of the product.
(2) Preparation of chemical products and reagents
By utilizing the action properties of lipase hydrolysis, synthesis and trans-fatty acid, it is possible to prepare chemical products with high chemical production costs. Erucic acid and its derivatives have a wide range of chemical applications and can be used in petrochemical, textile, chemical, light, and plastic industries.
In recent years, due to the widening of the use of erucic acid and the increasing demand for erucic acid in the international market, the production of erucic acid has increased at home and abroad. At present, the production method of erucic acid is to hydrolyze canola oil and mustard oil under high temperature and high pressure, and then rectify to obtain a high purity product. Researchers have found that Candida lipolytica and Geotrichum can be used jointly on rapeseed oil to produce erucic acid, glycerin, saturated fatty acids, fatty alcohols and other products. The enzymatic production of erucic acid requires low action conditions and can result in high-purity product, which is a development direction of erucic acid production.
Description of Calcium aluminate cement
Calcium aluminate cement, alumina cements or high alumina cements are obtained by the reaction at high temperature of lime (from limestone) and alumina (contained in natural minerals like bauxite). The product obtained after cooling is a hard mineral: calcium aluminate clinker. Ground into a fine powder, the clinker becomes calcium aluminate cement (CAC) which forms a paste when mixed with water. This has the ability to harden very quickly: it forms a rigid solid within 24 hours.
Application of calcium aluminate cement
There are two distinct ways to use calcium aluminates: as high-performance binders and as mineral reagents in a variety of industries.
As binders, calcium aluminates are used in concretes and mortars for specialized applications for their properties of resistance to corrosion, abrasion and heat combined with rapid hardening and the ease of controlling grading variations.
Calcium aluminate cements are also used in combination with other fine components. Hydraulic binders with new properties are then obtained. In this way, aluminates act as both a complex hydraulic binder and a mineral reagent interacting with the other components in the mix.
As reagents, calcium aluminates are found in non-hydraulic systems. This is the case in metallurgical treatments (iron and steel industry, foundry) where specific grades of calcium aluminate are used for their low-temperature melting properties and for trapping molten metal impurities.

Operators should always check the coolant, lubricant, brake fluid, hydraulic fluid, and fuel oil (water) position and quality, and pay attention to check the tightness of the vehicle. The requirements for maintenance of the truck crane during the running-in period can be summarized as reducing the load, strengthening the lubrication, strengthening the training, and paying attention to the inspection.
As long as the operator pays attention to and maintains and maintains the on-board hoisting period according to the manufacturer's requirements, it will reduce the occurrence of an early failure of the truck crane, prolong the service life, improve the operation efficiency, and let the truck crane bring you the greatest benefit. At the same time, it is necessary to strengthen the lubrication of the lubrication points of the truck crane. It is recommended that during the running-in period, the special requirements for grease filling the lubrication points should. Therefore, it is easy to cause wear of parts (especially the matching surface) during the running-in period of the truck, and the wear speed is fast. At this time, if the operation, it may cause damage to the components and happened an early failure of duty crane truck.
High-efficiency CSA Expansive Agent or<a href=”http://www.csacement.com/application/expansion-additive.html”>CSA Additive</a> is another application of our CSA BINDER. It is obtained by blending our CSA binder (clinker) which consists essentially of calcium sulphoaluminate and CaO. High-efficiency CSA expansive agent is always mixed with ordinary cement. When mixed in the proper proportions with ordinary cement and hydrated, cement mortar or concrete expands during the early stages of hydration. This expansion, when restrained, makes it possible to minimize drying shrinkage. Moreover, when the ratio of High-efficiency CSA Expansive Agent to ordinary cement is increased its high expansion qualities make it ideal for use in prestressed concrete. High-efficiency CSA Expansive Agent is being used in all sections of the construction fields and by a wide variety of concrete products manufacturers. The properties of High-efficiency CSA Expansive Agent conform to the standards of the manufacturer and to the Chinese relevant standards. 1.Low alkalinity. High-efficiency CSA Expansive Agent has a very low alkali content (R2O<0.3%) which is beneficial to avoid AAR in concrete. 2.Short stable stage of expansion. The stable stage of expansion is not more than 14 days, thus the ultimate strength of concrete is not affected. 3.Low dosage and high expansion capacity. The normal dosage of High-efficiency CSA Expansive Agent is 6~8% by the weight of ordinary cement, which is lower compared with other expansive additives such as UEA and CEA (their dosages are about 10~12% by the weight of cement) in the market. Features by using the CSA expansive agent To prevent cracking due to drying shrinkage and hydration heats;. To increases the water tightness of concrete and thus is useful for waterproofing buildings; To enable the manufacture of high strength concrete products through chemical prestressing.
