Scientists have developed that the boron nitride harder than diamond

Diamonds will no longer be the hardest substance in the world! At present, scientists have artificially synthesized nano-scale cubic boron nitride, which has exceeded the hardness of diamonds.

According to the American Wired magazine, diamonds are not the hardest material in the world. Currently, the Nature magazine published in January pointed out that a new material has surpassed the hardness of diamonds.

A research team from scientists at the University of Chicago and other universities pointed out that the superhard material cubic boron nitride is a form of ultra-hard material that compresses boron nitride particles. Scientists have shown that this transparent material even exceeds the hardness of diamonds, with a Vickers hardness of 108 GPa, while synthetic diamonds have a Vickers hardness of 100 GPa and that the material is twice the hardness of commercial cubic boron nitride.

The biggest secret of this material is the nanostructure. Tian Yongjun and other researchers began to use boron nitride particles like the onion structure (like the Russian doll structure) to compress to 15GPa at 1800 degrees Celsius, that's about 68,000 times the pressure of a car's tires, this crystalline material will recombine to form nanostructures.

Under the nanocrystalline structure, neighboring atoms share a boundary, which is like some apartment house. To make the material harder, scientists reduced the volume of the particles, making it harder to puncture.

Tian explained that the nanostructure makes the material harder to puncture. For boron nitride, the average size of the characteristic strength is 4 nanometers, but the corresponding result is that CBN is very stable at high temperatures.

In the future, the price of the superhard material will be comparable to the current commercial price of less hard CBN, which may be used in machining, grinding, drilling and cutting tools, as well as in the manufacture of scientific instruments.

Plastic welding process of conveyor welding machine is achieved in there ways, softening by external heat source, softening by mechanical motion and softening by electromagnetic action.

Conveyor belt welding machine used in hot plate welding can be said to be the most simple plastic welding technology. It is especially suitable for welding large plastic materials which need large area of welding surface. The general conveyor belt welding machine acts on the waterproof material. The heat produced softens the product. The period is longer. The molten resin will stick to the waterproofing board and it will not be easy to clean. Impurities that affect bonding strength will be formed for a long time. Pressure and time should be strictly controlled to ensure proper melting amount. With different kinds of resin or metal and resin joint, there will be insufficient strength. But the conveyor belt welding machine produced by our company adopts the way that welding device is simple and welding strength is high, and the shape design of products and welding parts is relatively easy. Generally, after melting and softening the two plastic planes to be welded, remove it quickly to electric heating plate and combine the two surfaces and apply force until it is cooling down.

Another way is that when the hot air flow of the welding machine is blowing to the joint area, melt the welding wire between the joint area and the waterproof material and the weld is formed by melting the soldered plastic with the filling material. The welding machine equipment of this method is light and easy to carry but the welding skill requirement of the operator is higher. The two technologies of hot rod and pulse welding are mainly used in the welding of plastic film with small thickness. The two methods are similar. They press two thin films together and use the instantaneous heat generated by a hot rod or nickel-chromium wire to complete the welding.

What is sewage truck

Sewage truck is a new type of sanitation vehicle that collects, transfers and transports sludge and sewage to avoid secondary pollution. The suction truck can self-prime and discharge, with fast working speed, large capacity, and convenient transportation. The  suction sewage truck is suitable for collecting and transporting liquid materials such as manure, mud and crude oil.

The suction truck adopts the domestic technology-leading suction pump vacuum pump, which has a large suction force and long suction stroke. It is especially suitable for the suction, loading, and unloading of sludge in the sewer, especially for sucking sewage mud, silt, stone, and brick. Large objects such as blocks.

The special part of the sewage truck consists of power take-off, drive shaft, vacuum suction pump, pressure tank body, hydraulic part, pipe network system, vacuum pressure gauge, visual fecal window, hand washing device, etc. Pump and high-quality hydraulic system, the tank can be opened later, and the double top is self-unloading. The dirt in the tank can be directly dumped through the back cover, which is of high vacuum (more suction than the suction truck), large tonnage, high efficiency, and wide usage.

The sewage truck has the same principle as the suction truck, but the sewage truck has different uses from the suction truck. The difference lies in the fact that the tank of the suction truck is a circular tank with a tighter structure, which can provide greater suction force under higher pressure and can be used for collecting and cleaning transportation sewage and sludge.

Since the suction hose is always immersed in the liquid surface, the air in the tank, and it becomes thinner and thinner because it is not replenished, so that the pressure in the tank is lower than atmospheric pressure, and the manure, under atmospheric pressure. , through the suction hose into the tank. Or because the siphon is close to the bottom of the tank, when the air is continuously discharged into the manure tank, it is compressed because there is no way out, so that the pressure inside the tank is higher than the atmospheric pressure, and the manure is discharged by the siphon and the suction hose under the action of compressed air. Outside the can.

The suction truck has the characteristics of high suction efficiency, self-priming, self-discharging, and direct irrigation. Pumping manure tank time: ≤ 5min, suction stroke: ≥ 8m. According to the characteristics of long service life, fast working speed, easy operation, and convenient transportation.

The glass plate is an important part of the sany boom pump truck. Although its volume is small, its technical content and processing cost are very high. At present, glass plate can serve for about 30,000 cubic meters of commercial concrete pumping. In order to improve the service efficiency of the arm gantry pump truck, it is very important to take corresponding measures to improve its service life.

Working characteristics of glasses plate

The eyeglass plate is a part of the S-shaped Sany truck mounted concrete pump distribution valve, connecting to the commodity concrete conveying cylinder. Driven by the swinging oil cylinder, the moving part S pipe swings from one commodity concrete cylinder to the other commodity concrete cylinder. The cutting ring vibrates with the S-tube attached to the eyeglass plate. The quick swing of the cutting ring causes intense wear between the eyeglass plate and the pre-mixed concrete. It also bears the impact of cutting off the stones. It can be seen that the eyeglass plate mainly works at room temperature and bears the impact force, shear force and very strong friction.

The main failure modes of eyeglass plate are wear and fracture failure. The wear between the eyeglass plate and cutting ring is abrasive wear. First, the cutting ring and the hole Angle of the eyeglass plate are blunt, and a smaller circular surface wedge-shaped trace is formed. The wear gap increases with the increase of abrasive particle size. When the gap is large to a certain value, the construction will be affected by severe leakage of the slurry. With the increase of pump height, the impact shear of the eyeglass plate will increase, the wear will be more intense, and it is prone to fracture and collapse.

It can be concluded from the above analysis that the surface of the eyeglass plate should not only have high hardness and wear resistance but also have the certain toughness and high fracture resistance.

In the manufacture of methacrylate resins and plastics. Methyl methacrylate is transesterified into higher methacrylates such as n-butyl methacrylate or 2-ethylhexyl methacrylate.

methyl methacrylate monomer is used in the production of methylmethacrylate polymers and copolymers, polymers and copolymers are also used in waterborne, solvent, and undissolved surface coatings, adhesives, sealants, leather and paper coatings, inks, floor polishes, textile finishes, dental prostheses, surgical bone cements, and leaded acrylic radiation shields and in the preparation of synthetic fingernails and orthotic shoe inserts. Methyl methacrylate is also used as a starting material to manufacture other esters of methacrylic acid.

Granules for injection and extrusion blow moulding which for their outstanding optical clarity, weathering and scratch resistance are used in lighting, office equipment and electronics (cell phone displays and hi-fi equipment), building and construction (glazing and window frames), contemporary design (furniture, jewellery and tableware), cars and transportation (lights and instrument panels), health and safety (jars and test tubes) and household appliances (microwave oven doors and mixer bowls).

CAS Number: 80-62-6

 Methyl methacrylate (MMA) is used in the manufacture of polymethyl methacrylate (PM-MA), coatings, lubricant additives, wood sizing agents, paper polishes, etc.

 MMA is not only an organic chemical raw material, but also can be directly applied as a chemical product. As an organic chemical raw material, it is mainly used in the production of PM-MA and also used in the manufacture of polyvinyl chloride additive ACR and as a second monomer in the production of acrylic fibers. In addition, it has been widely used in adhesives, coatings, resins, textiles, papermaking and other industries. As a chemical product, it can be directly applied to leather, ion exchange resin, paper polish, textile auxiliaries, leather treatment agents, lubricating oil additives, crude oil pour point depressants, wood and soft wood sizing agents, motor coils permeabilizers, insulating and potting materials, and plasticizers for plastic type emulsions, floor polishing, unsaturated resin modification, higher esters of methacrylic acid, and many other fields.

 MMA is used as an organic synthetic monomer and in the manufacture of other resins, plastics, coatings, adhesives, scale inhibitors, lubricants, wood infiltrants, motor coil impregnants, paper polishes, auxiliaries for printing and dyeing, and insulating potting materials.

 As a monomer for PM-MA, it is also used in the manufacture of other resins, plastics, coatings, adhesives, lubricants, wood and cork sizing agents, and paper polishing agents.

Precautions for storage of MMA

MMA is usually mixed with polymerization inhibitors. It should be stored in cool ventilated warehouses and kept away from fire, heat sources, and light. The temperature in warehouses should not exceed 37°C. It requires to sealed in packaging and must not come into contact with air. It should be stored separately with oxidants, acids, alkalis, halogens, etc. to avoid mixing. It is not suitable for large-scale or long-term storage. Use explosion-proof lighting and ventilation facilities and do not use mechanical equipment and tools that are prone to generate sparks. In its storage areas, spill treatment equipment and suitable containment materials should be prepared.

Optical cable handover box is a kind of handover equipment which provides end-to-end and jump-over for main layer and distribution layer optical cables. After the cable is introduced into the cable junction box, the main layer cable and the distribution layer cable are connected by jumping fibers after being fixed, terminated and distributed.

The thing placed inside is the end of the optical cable, and the function of the end of the optical cable is to gather two or more signals of the original unrelated computer room together, and then use tail fiber to connect two unrelated cables according to need. Its signal source is the computer room.

Optical intersection boxes collect all optical signals. Optical signals can not be used directly. Photoelectric conversion equipment is needed to convert optical signals into electrical signals. Therefore, if you want to use the signals in optical intersection boxes directly, it is very expensive.

Similar to the optical cabinet, there are also electrical cabinets. The appearance of the electrical cabinet is not different from that of the optical cabinet. However, the signals collected in the electrical cabinet are electrical signals, which can be directly used without conversion. The signal source of the electrical cabinet is also the computer room.

Fiber optic cable junction box is a kind of outdoor connection equipment. The most fundamental requirement for it is to be able to withstand dramatic changes in climate and harsh working environment. It should have the characteristics of waterproof gas condensation, waterproof and dust-proof, pest and rodent prevention, and strong impact damage resistance. It must be able to withstand the harsher external environment. Therefore, waterproof, moisture-proof, dust-proof, impact-proof, pest and rodent-proof requirements are relatively high on the outside of the box; temperature and humidity control requirements are very high on the inside of the box. According to international standards, the highest standard for these projects is IP66. But there are not many cases that can meet this standard.

At present, the main cabinets used in China are KRONE cabinet in Germany, which is made of unsaturated polyester glass fiber reinforced material (SMC) and has good performance in waterproof, moisture-proof and impact-proof. The imitation of domestic reference KRONE boxes is mainly iron metal boxes (generally up to IP65 standard). For metal box, because of its poor performance in waterproof gas condensation, it is doomed not to be widely used and gradually eliminated. Some domestic imitations are quite different from KRONE imported from Germany in terms of waterproof gas condensation and shock resistance due to material performance problems. In addition, due to the poor anti-aging performance of sealant strip, the performance of waterproof and dust-proof is also common. Of course, it is acceptable to reduce performance requirements and investment when the external environment of the installation location of the cable junction box is better.
