Application and performance of high molecular polyethylene board
The high molecular polyethylene sheet is mixed, calendered, sintered, cooled, high pressure shaped, demolded, and finally formed. The polyethylene sheet has good impact resistance, low friction coefficient and excellent self-lubricating properties. Polyethylene sheet is special in that it is very difficult to ignite. If it is ignited, it can be automatically extinguished after about 10 seconds.
Now our high molecular polyethylene board is a kind of engineering plastic with superior performance. Its characteristics are superior to other plastic products. It is the plastic king of plastic products, such as high wear resistance, impact resistance and low friction coefficient of the board. Good self-lubricating properties, excellent low temperature resistance, chemical resistance, non-toxicity, five flavors and other properties are unmatched by other plastic products.
In addition, the high-molecular polyethylene board is also a very safe and healthy new type of board, which is known as a green and new type of board. The polyethylene sheet is also a polymer having a very high viscosity and is in the form of a powder having a typical particle size ranging from 100 to 200 μm. Because of its high viscosity, high-molecular-weight polyethylene sheets cannot usually be processed by ordinary thermoplastic molding methods. Instead, the ultra-high molecular weight polyethylene particles are melted and sintered into a billet under high pressure by a molding or plunger extrusion process. Or profiles, if necessary, for subsequent machining.
The service life of polymer polyethylene board is higher than that of steel, and it is 3-7 times of carbon steel and stainless steel; the friction coefficient is small, self-lubricating, non-absorbent, non-bonding material, high impact strength, good mechanical energy, acid resistance Alkali, salt corrosion, no aging, low temperature resistance, clean and non-toxic, light weight, specific gravity is 1/8 of steel. Therefore, it is the best information for storing and transporting equipment fabrics in bulk materials, such as storage bins, launders Wait.
Because it has excellent anti-friction, self-lubricating and non-sticky, the above-mentioned powdery materials do not adhere to the storage and transportation equipment, ensuring stable transportation. The high wear-resistant plate is used for devices under various environmental conditions, and can be planned into an assembly connection structure, which can be customized according to user requirements and is convenient for device repair. For example, the use of hoppers, chutes, metallurgical supply funnels, etc., which are difficult to operate, can completely solve the problem of bonding and blocking in the transportation process, and complete safe, efficient and normal production. Utilizing its low mechanical properties, it is often used as a metal lining material, which can effectively combine the strength of metal with the wear resistance of U-polymer polyethylene sheets and the performance required by customers, and our flame-retardant type is high. Molecular polyethylene board is widely used in China’s electric power, coal, steel, cement, coking and other industries. It can effectively prevent fire caused by spontaneous combustion of coal and other factors, so it is now used in our daily life. big.
Polyethylene sheet in the food machinery industry: non-toxic, impact-resistant, corrosion-resistant, sound-absorbing, light weight, do the food machinery curve rail, container guide rail, planetary gear. Push the screw, powder pellet funnel, various sauce stuffing devices, etc. Filling line gears and sprockets can reduce the breakage of bottles when transporting and reduce noise.
Polyethylene sheet in the chemical paper industry: anti-corrosion, wear resistance, lubricity, non-adhesive, etc. made of acid-resistant pump, chemical pump pusher, bushing, pickling tank protection board, slot conveyor of screw conveyor equipment, Suction box panel, log conveyor belt roller, dewatering tool, forming plate, wiper plate.
Our high molecular weight polyethylene sheet not only retains the high impact strength of ultra high molecular weight polyethylene sheets, but also has the characteristics of low friction coefficient and self-lubrication.
Then comes our high-performance polyethylene sheet with excellent performance and at the same time, it can meet the different performance requirements of customers, such as flame-retardant polymer polyethylene board, which is difficult to ignite and can be removed in 3-10 seconds after being separated from the fire source. It is automatically extinguished, and it does not drip, the amount of smoke is small, and the volatile gas is harmless to the human body. After testing by the National Flame Retardant Materials Laboratory, the product is considered to be a green environmentally friendly material, which has high promotion and use value.
