Plastic screw is used in food conveyor, used for transporting food classification, and UHMWPE material self-lubrication and high wear resistance, do not drop powder and other characteristics. The transmission of food will be more smooth and fast, the high wear resistance of the material makes its service cycle greatly increased. It saves the cost of manual classification and speeds up the classification time.
Ultra high molecular weight polyethylene (UHMW-PE) is linear polyethylene with an average molecular weight of more than 1.5 million. Due to its high molecular weight (ordinary polyethylene 20-300,000), UHMW-PE has incomparable comprehensive performance of ordinary polyethylene and other engineering plastics:
1) High wear resistance, 4 times higher than nylon 66 and ptfe, 6 times higher than carbon steel, is the best of all synthetic resins at present.
2) High impact strength, 2 times of polycarbonate, 5 times of ABS, and can maintain high toughness at liquid nitrogen temperature (-196ºC).
3) Good self-lubrication, its self-lubrication is similar to ptfe, friction coefficient is only 0.07-0.11; Only the steel friction coefficient of 1/3-1/4.
4) The absorption value of impact energy is the highest in all plastics, and the effect of noise elimination is very good.
5) High chemical stability, in a certain range of temperature and concentration can withstand the action of various corrosive media and organic media.
6) Strong adhesion resistance, second only to the "plastic king" PTFE.
7) Completely sanitary and non-toxic, can be used to contact with food and drugs.
8) The density is the smallest in all engineering plastics, 56% lighter than ptfe, 22% lighter than polycarbonate; One eighth the density of steel, and so on
Our company uses more than 5 million molecular weight of raw materials production, because of the above excellent comprehensive performance, UHMW-PE is known as the "amazing plastic" by European countries and has been widely used in many industries.
