After long-term use of plastic buckets, there are inevitably several obvious damage marks on the surface, including scratches from sharp objects. The solution to improve the scratch performance is to minimize the roughness of the polymer bottom surface and reduce the scratches of the tire. Shoulder, so as to achieve higher wear resistance. In addition, it is also a good choice to use materials that can improve its wear resistance.

Ways to improve the wear resistance of plastic buckets:

①Polytetrafluoroethylene, which has a low friction coefficient among all anti-additives. The molecules abraded during the friction process will form a lubricating film on the surface of the part. It has good lubricity and wear resistance under frictional shear force. It is a commonly used wear-resistant additive in high-load applications.


②Molybdenum disulfide: Another common name for molybdenum disulfide is Moly, which is mainly used as a wear-resistant additive for nylon plastics. Molybdenum disulfide acts like a crystallization agent to increase the crystallinity of nylon and make nylon material produce a harder and more abrasive surface. Molybdenum disulfide has a high affinity for metals. Once adsorbed on the metal surface, the molecules of molybdenum disulfide will fill the metal surface with microscopic pores, and make the metal surface more slippery.


③Graphite: The chemical structure of graphite is a unique lattice structure. This unique chemical structure allows graphite molecules to slide easily on each other with little friction. This abrasion resistance is especially important in environments with water. This characteristic makes graphite an ideal wear resistance additive for many applications placed in water.


Although some plastic barrels already have good wear resistance, adding various wear-resistant additives can improve their wear resistance. Plastic composite materials made of additives like silicone oil, glass fiber, carbon fiber and aromatic polyamide fiber have self-lubricating properties, and can reduce the pressure of matching parts, thereby improving the wear resistance of the material.
