Ultra-high molecular polyethylene food gear is characterized by:
1. Non-sticky material: the surface absorption force is very weak, and its anti-adhesion ability is second only to PTEE. Its water absorption rate is almost zero, only 1% of PA6.
2, wear resistance: polyethylene lining wear resistance in the first engineering plastics, the larger the molecular weight of the wear resistance, even more than many metal materials (such as carbon steel, stainless steel, bronze, etc.). The wear index of mortar is only 1/5 of PA66 and 1/10 of HDPE and PVC. Compared to metal, it is 1/7 of carbon steel and L /27 of brass.
3, the static friction coefficient of self-lubrication is 0.07, self-lubrication is good, second only to polytetraethylene (PTFE) under the condition of no lubricant; Better lubricity than steel and brass with added oil. Is an ideal lining, the friction parts of the equipment, in addition to improve wear-resisting life, but also can receive the effect of energy saving.
4, corrosion resistance: polyethylene lining board is not corroded in lye, stable in 75% concentrated sulfuric acid, 20% nitric acid, it is also stable to sea water, liquid detergent.
5, impact resistance: polyethylene lining board molecular weight is large, chemical bond is close. Therefore, strong impact resistance, will not break. Impact strength is 10 times of nylon 66, 20 times of polyvinyl chloride, 8 times of polytetrafluoroethylene; The impact strength is about 2 times of impact resistant PC, 5 times of ABS, more than 10 times of POM and PBTP. Especially in the low temperature environment, its impact strength reaches the highest value, and its flexibility can provide a very safe and reliable guarantee for the conveying system.
6, low temperature resistance: polyethylene car board is a kind of excellent toughness material, its low temperature resistance is also very excellent, at -269 DEG C low temperature, still has a certain ductility, but no signs of brittle crack. It is especially suitable for Northeast China and Inner Mongolia.
