The technical principle of microbubble generator is that the surface of microbubble is negatively charged, and the negative charge of microbubble generator is higher than that of ordinary microbubbles. Generally, the surface load of microbubbles below 30um is about - 40mv, which is one of the reasons why microbubbles can gather together for a long time without breaking. Using the electronegativity of micro bubble, it can adsorb the positively charged substances in water, which has a good effect on the adsorption and separation of suspended solids or pollutants in water.

The technical principle of microbubble generator is that the self pressurization of microbubbles is related to the internal pressure and surface tension of dissolved bubbles. The smaller the diameter of bubbles, the greater the internal pressure. Due to its small diameter and large specific surface area, the internal pressure of microbubbles is much higher than that of the external liquid, while due to the advantages of internal pressurization and large specific surface area of microbubbles, the gas solubility of microbubbles is hundreds of times of that of millimeter bubbles. Because the solubility is closely related to the pressure, the interface will reach the supersaturated state when the internal pressure of the micro bubble increases to a certain threshold. When more gas in the bubble is dissolved into the water, it will gradually dissolve and disappear.

The technical principle of microbubble generator is that the shrinkage of microbubbles will shrink or expand continuously after they are produced in water because of self pressurization, and the diameter of microbubbles will change all the time. According to the latest research, 20um ~ 40um bubbles will search to 8um at the speed of 1.3um/s, and then the shrinkage rate will increase dramatically, and then it may further split into nano bubbles or completely dissolve in water. The surface of the bubble with high interfacial electromotive force will absorb charged ions such as OH -, and around the OH - ion layer, there will be counter charged ions such as H +, so that the surface of the bubble will form a double electric layer. The potential of the double electric layer interface is also called the interfacial electromotive force. The level of the interfacial electromotive force largely determines the adsorption performance of the bubble interface.

Because of the shrinkage of micro bubbles, charge ions gather at the interface of bubbles in a period of time. Until the bubbles are completely broken and dissolved, the dynamic potential of the interface will increase all the time, showing the better adsorption performance of charged particles in water.

In addition to the selection of single items and popular elements of men’s clothing, color matching is especially important. If you don't pay attention to wearing, it is easy to enter the color misunderstanding at the critical moment. This article takes you to master five practical color matching methods of men's clothing for spring and summer, so that you can easily go out without thinking too much.

Five Color Matching Methods of Men's Clothing

Khaki and white

Khaki and white are actually a good match. Common khaki pants are paired with a white T-shirt or white shirt, and a pair of white sneakers that are fashionable, giving a clean and comfortable feeling. If you like to wear white, you can choose a white and khaki jacket to add layering to pure white.

Blue and white

White is most people’s first choice because it can be matched with any color, but it takes a lot of effort to dress smartly. When white is paired with blue, in order to avoid giving a top-heavy visual sense, choosing a white top (shirt or T-shirt) with blue pants is highly recommended.

Blue and white

Blue and green

The combination of blue and green is the most vivid color combination on the streets and catwalks of Fashion Week this season. Although blue is an iconic color for men, green is not easy to wear for everyone and look good on it. if it is the first time to choose a green item, it is recommended to start with small accessories like a belt or a tie.

Black and white

Black and white has always been a must-have item combination for boys' wardrobes, and it is also the most secure and error-free universal item for men to wear this season.

Khaki and blue

Khaki and blue

In addition to matching green and white, blue can also be matched with khaki. Choose a light khaki jacket for dark blue pants and a light blue top for khaki pants.

Practical Color Matching Patterns of Men's Clothing for Spring and Summer

Most boys do not have much clothes. Changing these sets of clothes every day seems to be boring. In fact, it doesn’t have to be the case, and it depends on how you wear the clothes.

Actually, if a man can only have four tops, four pants and two pairs of shoes, they should be:

1. For white t-shirts, the collar should not be too high, and most people can't hold deep V or large U collars. One-line collars or large round collars are recommended. It is recommended not to use threaded mouths. Rough edges or simple thin edges are better.

2. The white oxford spinning shirt is very suitable for men to have one. In fact, it is suitable for wearing in three seasons in a year. If you have one, it is better to have a collar button.

3. Blue POLO shirt, it is recommended to be a little darker blue. You can't hold the sapphire blue shirt. The sky blue t-shirt sounds beautiful but looks not pretty. Sky blue is only suitable for shirts. It is best to have white lines on the cuffs and collar or it would be too dull. There is no decoration in other places, not even a small logo pattern.

4. The red grid gingham short-sleeved shirt or the red-black grid short-sleeved shirt, the main purpose of this shirt is to complement your outfit.

5. You can dress for the lower half in navy blue, black slim or small leg pants, khaki slim pants, and slim wash blue jeans.

6. For the shoes, it’s better to have white shoes (leather is the best) and half-carved brogue brown leather shoes. These four tops can take any of the four pairs of pants. Similarly, pants can also take any top. The same goes for shoes. Therefore, as long as with 10 pieces of clothing, you can wear them without repeating a day for a month.

This is just a pattern in color matching. More importantly, the different ways of wearing will make people feel very different. For clothes: a little difference in details, the effect is very different.

Five Practical Color Matching Methods of Men's Clothing for Spring and Summer

It is worth noting that some clothes can be worn in one way. Pure business shirts cannot be worn open, trousers cannot be rolled up, and linen shirts cannot be used for business ties. The difference is that some clothes are worn more ways and some less.

Follow the five color matching methods for men's clothing introduced above, match them with tops and bottoms with the similar style, and practice the matching method, so you can easily go out without thinking to much about what and how to wear.

Zhiyun-Tech just announced their new flagship stabilizer for higher payloads – Zhiyun CRANE 3S. With its new powerful motors, the gimbal can support loads up to 6.5kg (14.33 lbs) so it should be able to handle many cinema cameras. It also offers modular design with EasySling Handle and SmartSling Handle and it can be used with EasyRig. It is available now in three kits.

The Chinese gimbal manufacturer Zhiyun-Tech first introduced the new gimbal design with the CRANE 3 LAB and Weebill LAB back in 2018. The aim of the gimbals was to improve the ergonomics for easier underslung filming mode – when the camera is underneath the gimbal. Since then, the smaller stabilizer Weebill LAB already got its improved successor with the Weebill-S compact gimbal in October 2019. Now the time has come to improve the larger model. Zhiyun-Tech just announced its new flagship stabilizer for higher payloads – the Zhiyun CRANE 3S. Let’s take a short look at its features and specs.

Zhiyun CRANE 3S

One of the most significant changes in the new Zhiyun CRANE 3S are its new, more powerful motors which allow it to handle up to 6.5kg (14.33 lbs) payloads allowing to use the gimbal with heavier camera setups. According to Zhiyun, the gimbal will be able to handle setups with Canon EOS 1DX, Blackmagic Pocket Cinema Cameras, Canon Cinema EOS, Sony FS and FX series, and RED Digital Cinema cameras. It should even be possible to balance a Blackmagic URSA on the gimbal, although it has to be mounted reversed.

With CRANE 3S, Zhiyun-Tech also introduces a detachable second handle with two options:

EasySling Handle extends the grip for more comfort upright & underslung operation

SmartSling Handle features an intuitive control panel and OLED screen, for direct camera & gimbal parameter adjustment

It is possible to combine both handles as they are easy to fit and remove. Both provide multiple thread holes in different sizes to mount accessories. The modular design makes the CRANE 3S compatible with motorized dollies, jibs, cable cams, EasyRig, etc. Especially the compatibility with EasyRig is important in my opinion as some setups with the CRANE 3S will be very heavy for handheld operation.

With three 18650-format batteries, CRANE 3S can run for up to 12 hours. A DC-in power port on the battery compartment allows input of up to 25.2V for direct charging. To support long shoots with larger setups, Zhiyun introduces the TransMount PowerPlus Battery Pack which houses six 18650 batteries and independently provides 18 hours of runtime for the gimbal.

The newly-designed locking system can lock all three axes without noticeable swinging. The modular design comes with double locks for additional safety. A larger lens support has been added to the zoom and focus system.

Image Transmission Module

Zhiyun-Tech’s TransMount Image Transmission Module is, of course, compatible with the CRANE 3S. With the transmitter, the video can be streamed to up to three monitoring devices including smartphones. The ViaTouch 2.0 system in the ZY Play app bridges the communication gap between stabilizer, camera and monitoring devices, allowing users to adjust camera and gimbal parameters remotely. The ViaTouch 2.0 system also enables a visualized remote motion control for the gimbal.

Because of the bad working environment, hull to corrosion by seawater chemical corrosion, electrochemical corrosion and marine organisms and microorganisms; hull under high wave and alternating load; the ship shape processing method of complex factors such as, so the steel hull structure strict requirements. First of all, good toughness is the most critical requirement. Besides, it requires high strength, good corrosion resistance, welding performance, processing performance and surface quality. In order to ensure quality and ensure enough toughness, the chemical composition of Mn/C is above 2.5, and the carbon equivalent is also strictly required, and it is produced by a steel factory approved by the ship inspection department. The strength grade of the structural steel used in the hull is divided into the general strength structural steel and the high strength structural steel according to the minimum yield point. Hull structural steel is divided into two kinds: general strength and high strength steel. The general strength steel is divided into four grades according to the quality: A, B, D and E. The high-strength steel is divided into two strength grades and three quality grades; AH32, DH32, EH32, AH36, DH36 and EH36.

The standard strength steel of China Classification Society is divided into four quality grades: A, B, C and D, namely, CCSA, CCSB, CCSC and CCSD. The high strength structural steel regulated by China Classification Society is three strength grade and four quality grade.

Classification according to the classification society, there are ABS, LR, GL, DNV, BV, NK, KR, RINA, CCS, etc.

In order to cope with market changes, the research and development of color sorting machine  in China is also making progress. Various enterprises have carried out extensive and continuous research on color sorting machine, especially ore enterprises. From photoelectric (analog) technology, CCD (digital) technology application, to intelligent color sorter cloud technology and Internet of Things technology research and application, color sorter technology and application has been constantly updated.

In the application of color sorting machine for Barite, the performance may be unstable and need to be repaired and re-adjusted frequently. This is mostly due to the instability of the optical system composed of the light source, background and imaging system of barite color sorting machine, especially on the equipment with simple optical system.

In addition, there are more stive and dust in the application environment, and vibration and interference are larger, and temperature changes will affect the working status of color sorter, resulting in inaccurate detection signal or changes of the delay time in the control of high-pressure valve opening, thus affecting the accuracy of impurity injection action. In addition, the matching degree of process and material problems will have a certain impact on the effect of ore color separation.

On the basis of independent innovation, Barite sorting machine enterprises need to make breakthroughs in the following aspects:

(1) The application of new light source and mixed light source; the development of better spray valve improves productivity while reducing the take-out ratio, adopting to more products of color selection; the research of signal processing and control technology of CCD color sorter should be strengthened to solve the problems of randomness and multi-channel of CCD color sorter.

(2) Applying new high-speed and ultra-large-scale microprocessors and embedding more recognition algorithms improves the practicability of the system;

(3) With the "Internet+” as a tool, we will vigorously improve the platform construction of big data cloud system, equipped with fault diagnosis and online communication functions, and we can turn to the enterprise after-sales service front desk for help in real time in case of failure, requesting technical guidance. Realize the intellectualization and remote intellectualization of color selection operation, and bring infinite value-added business information to customers through scientific and effective analysis.

Performance comparison of Pu sandwich board ,rock wool and glass wool composite board

Due to the improvement of fire protection requirements for buildings, the market situation of rock wool composite board and glass wool composite board with better flame retardant grade is better in recent years.
Rock wool and glass wool composite board is based on inorganic fibers as insulation core material, although it has A-grade flame retardant performance, but the gap between fibers naturally forms air passage (air gap), which intensifies the heat conduction effect of the inner and outer layers, and seriously affects the thermal insulation performance of the board.
Rockwool and glass wool composite boards meet the flame retardant requirements of the board, while abandoning the requirement of energy-saving board for thermal insulation, is a trade-off method, and the shape of the board is poor, so it can only be used as transitional board.

Most people agree with the quality and effect of PU board, but hold back its price. We make a cost comparison, assuming that the price of PU plate (steel plate 0.5mm, PU density 42kg/m3) is 140 yuan/m2;
EPS plate (internal and external steel plate 0.4mm, EPS density 7kg/m3, commonly used specifications) selling price 50 yuan/m2;
Rock wool board (internal and external steel plate 0.5mm) selling price 90 yuan/m2;
Because PU plate has good flexural capacity, it can reduce the amount of secondary steel (C, Z section) and installation labor cost (about 19.5 yuan/m2).

Nitrification inhibitor refers to a class of chemical substances that inhibit the biotransformation of ammonium nitrogen into nitrate nitrogen (NCT). Nitrification inhibitors reduce the formation and accumulation of nitrate in soil so that it can reduce the loss of nitrogenous fertilizer in the form of nitrate nitrogen and the impacting on ecological environment. Some results show that, although nitrification inhibitor can reduce nitrogen leaching loss and greenhouse gas (nitrogen oxide) emission, it has a positive effect on improving fertilizer efficiency under certain conditions. However, nitrification inhibitors have not been widely used due to factors such as craftwork, cost and their own effects on the environment. It is necessary to search for some nitrification inhibitors which are effective in inhibiting nitrification and do not pollute the environment. 

Brief introduction of 3,4-Dimethylpyrazole Phosphate

• They can selectively inhibit the activity of nitrobacteria in soil. 
• Ammonium nitrogen can be absorbed by soil colloids and not easily lost. However, under the condition of soil permeability, ammonium nitrogen can be transformed into nitrate nitrogen under the action of microorganism, which is called nitrification.
• The speed of reaction depends on soil moisture and temperature. The speed of nitrification is very slow when it is below 10 °c. When the temperature is above 20 °C, the reaction rate is very fast. Except for some crops, such as rice, which can absorb ammonium nitrogen directly under irrigation, most crops absorb nitrate nitrogen. But nitrate is easy to be lost in soil. Rational use of nitrification inhibitors to control the rate of nitrification reaction can reduce the loss of nitrogen and increase nitrogen use efficiency. Nitrification inhibitors are usually mixed with nitrogen fertilizer and then applied.

Modified octadecylamine (ODA) based Langmuir-Blodgett (LB) films were investigated. These films may find uses as ion exchange systems. ODA may be used to functionalize carbon nanomaterials. Thermal decomposition of metal nitrates in the presence of ODA may be used to obtain metal oxide nano crystals of controlled size and shape. ODA based LB fims was used to realise enzymatic field effect transistor (ENFET) biosensors.

Octadecylamine (cas 124-30-1) is used as asphalt emulsifier, lubricant and dispersants. It is obtained by ammoniation and hydrogenation of stearic acid.
For making octadecyl ammonium salt and a variety of additives, such as cationic grease thickener, mineral flotation agents, asphalt emulsifying agent, antistatic agent, water treatment corrosion inhibitor, surface active agent, fungicide, color film, couplers, etc.

It acts as a cationic surfactant and find applications is hair rinse bases, wood preservatives, textile softeners, dyeing auxiliaries and pigment grinding aids. It is used in boiler as an additive, which prevents the corrosion arises due to steam. It is a basic building block and used as an intermediate in the preparation of their amine derivatives, ethoxylates and amides. Metal oxide nano crystals having controlled size and shape are prepared by the thermal decomposition of metal nitrates with octadecylamine.

Uses: textile auxiliaries, chemical fertilizer anti-agglomeration agents, mineral flotation agents and as detergent raw materials. It also has octadecylamine solubility.

OVER VIEW OF ULTRAFILTRATION CERAMIC MEMBRANE ELEMENT

Ultrafiltration ceramic membrane/ceramic filter is a variety of membrane filtration in which forces, such as pressure or concentration gradients, cause separation through the semi-permeable membrane. High molecular weight suspended solids and solutes remain in the so-called retentate while water and low molecular weight solutes pass through the membrane in the permeate (filtrate). The pore size of the ultrafiltration ceramic membrane is in the range of 0.01μm ~ 0.05μm, suitable for the separation, concentration, and purification of macromolecules and small molecules.

A versatile and economical solution for clarification, concentration, and purification of liquids, ultrafiltration membrane filter could remove emulsified oils, metal hydroxides, colloids, bacteria and viruses, emulsions, dispersed material, suspended solids, and other large molecular weight materials from water and other solutions. Ultrafiltration ceramic membrane also serves in critical parts of the production processes of fruit juice, milk and whey, electrocoat paints, pharmaceuticals, poly-vinyl alcohol, and indigo dye. It is key to surface water treatment for potable uses and wastewater treatment for reuse, such as palm oil wastewater and paper mill wastewater treatment. Ultrafiltration ceramic membrane is used to recycle flow or add value to later products and more. In many cases, ultrafiltration ceramic membrane is used for prefiltration in reverse-osmosis plants to protect the reverse-osmosis process. Ultrafiltration ceramic membrane is an effective means of reducing the silt density index of water and removing particulates that can foul reverse osmosis membranes.
