The main cleaning and safety effects are played in the ultra-polymer wear plate. The food and beverage industry in the beverage light industry first uses its excellent wear resistance, impact resistance, self-lubricity and non-toxicity to produce a variety of gears, cams, conveyor line wear barriers, gaskets, guide rails and anti-friction, self-lubricating linings. Sets, fabrics, etc. Such as: food machinery guardrail, star wheel, guide gear, bearing bushing, etc.
Polymer wear plates are widely used because of their strong physical and chemical properties. For some special environments, the demand for polymer wear plates is even stronger. For example, in ball mill lining applications, strong strength is required. Initially this function was mainly determined by the improvement of the wear plate.
Ultra high molecular weight polyethylene sheets have excellent chemical resistance. It does not corrode in all bases and acids except concentrated nitric acid and concentrated sulfuric acid and can be used at temperatures (concentrated hydrochloric acid at 80 ° C). It is also stable in <20% nitric acid and <75% sulfuric acid. Washing water and liquids are also very safe.
However, ultrahigh molecular weight polyethylene sheets are very easy to swell in aromatic perfumes or halides (especially at higher temperatures), so care should be taken when using them. Thermal function; according to ASTM (load 4.6kg / cm2) method, the heat distortion temperature is 85 ° C, under small load, the working temperature can reach 90 ° C, because the ultra high molecular weight polyethylene plate is an excellent corrosion resistant material .
Therefore, its low temperature resistance is also very good, and it has a certain ductility and no brittle crack marks when applied at a low temperature of -269 °C. Ultra high wear resistance; one of the most famous functions of ultra high molecular weight polyethylene sheets is their high wear resistance, which is very valuable in many engineering applications. In today's plastics, its wear resistance is the best, and even many metal materials (such as carbon steel, stainless steel, bronze, etc.) have the same conventional wear resistance.
