A含二硫化钼高分子聚乙烯板UHMWPE耐磨板
高分子聚乙烯板是高聚物的一种，有它的特殊性其机械力学性能受温度、相对分子质量的影响很大，在设计高分子聚乙烯板机械零件时应给予高度重视。
随相对分子质量的增大超高分子量聚乙烯的耐磨损性增强，伸长率随相对分子质量的增大而降低，屈服强随相对分子质最的增大也下降，最大强度随相对分子质量的增大而略有增高，冲击强度随相对分子质量的增大而增大，高分子聚乙烯板相对分子质量300万左右达到最大值，超过300万左右后，反而降低，冲击强度随温度的增高而变大，但在25℃左右时达到最大值。
UHMWPE板比其他材料更耐磨，包括金属、尼龙、聚氨酯和氟塑料。这是一种极其坚韧的塑料，具有很高的耐磨性和抗磨性。聚乙烯的多功能性使其成为无数需要耐久性、低摩擦和耐化学性的工业应用中的流行塑料。UHMWPE板易于制造和加工.
As a kind of high polymer, the mechanical properties of polythene sheet
are greatly influenced by temperature and relative molecular weight, so
much attention should be paid to the design of mechanical parts of
polythene sheet. With the increase of molecular weight, the wear
resistance of UHMWPE increases, the elongation decreases, and the yield
strength decreases with the increase of molecular weight, the maximum
strength increases slightly with the increase of the relative molecular
weight, and the impact strength increases with the increase of the
relative molecular weight, the impact strength increases with the
increase of temperature, but reaches the maximum value at about 25 °C.
Uhmwpe is more abrasion resistant than other materials, including metals, nylon, polyurethane and fluoroplastics. It is an extremely tough plastic with high wear resistance and abrasion resistance. Polyethylene's versatility has made it a popular plastic for numerous industrial applications that require durability, low friction, and chemical resistance. Uhmwpe board is easy to manufacture and process.
