? 高分子聚乙烯板是高聚物的一種，有它的特殊性其機(jī)械力學(xué)性能受溫度、相對(duì)分子質(zhì)量的影響很大，在設(shè)計(jì)高分子聚乙烯板機(jī)械零件時(shí)應(yīng)給予高度重視。

? 隨相對(duì)分子質(zhì)量的增大超高分子量聚乙烯的耐磨損性增強(qiáng)，伸長(zhǎng)率隨相對(duì)分子質(zhì)量的增大而降低，屈服強(qiáng)隨相對(duì)分子質(zhì)最的增大也下降，最大強(qiáng)度隨相對(duì)分子質(zhì)量的增大而略有增高，沖擊強(qiáng)度隨相對(duì)分子質(zhì)量的增大而增大，高分子聚乙烯板相對(duì)分子質(zhì)量300萬(wàn)左右達(dá)到最大值，超過(guò)300萬(wàn)左右后，反而降低，沖擊強(qiáng)度隨溫度的增高而變大，但在25℃左右時(shí)達(dá)到最大值。

? UHMWPE板比其他材料更耐磨，包括金屬、尼龍、聚氨酯和氟塑料。這是一種極其堅(jiān)韌的塑料，具有很高的耐磨性和抗磨性。聚乙烯的多功能性使其成為無(wú)數(shù)需要耐久性、低摩擦和耐化學(xué)性的工業(yè)應(yīng)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.
