什么是轻型路板，临时路板/轻型路板的抗压性怎么样

轻型路板 临时路板 高分子轻型车路垫随相对分子质量的增大超高分子垦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，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℃左右时达到值。

With the increase of relative molecular mass, the wear resistance of ultra-high molecular polyethylene is enhanced, the elongation decreases with the increase of relative molecular mass, the yield strength decreases with the increase of the maximum relative molecular mass, the strength increases slightly with the increase of relative molecular mass, and the impact strength increases with the increase of relative molecular mass. The relative molecular weight of polymer polyethylene plate is about 3 million to reach the value. After more than 3 million, it decreases, and the impact strength becomes larger with the increase of temperature, but it reaches the value at about 25℃.
