什么是輕型路板，臨時路板/輕型路板的抗壓性怎么樣

輕型路板 臨時路板 高分子輕型車路墊隨相對分子質量的增大超高分子墾聚乙烯的耐磨損性增強，伸長率隨相對分子質量的增大而降低，屈服強隨相對分子質最的增大也下降，強度隨相對分子質量的增大而略有增高，沖擊強度隨相對分子質量的增大而增大，高分子聚乙烯板相對分子質量300萬左右達到值，超過300萬左右后，反而降低，沖擊強度隨溫度的增高而變大，但在25℃左右時達到值。

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℃.
