#聚乙烯板#
一、特性
1.含硼聚乙烯板的耐磨性在塑料中排名第一,分子量越大,材料的耐磨性和抗冲击性越高。
2.含硼聚乙烯片材的冲击强度是现有塑料的价值,即使在70℃时仍有很高的冲击强度。
3.自润滑;
4.含硼聚乙烯板吸水率很低,因此其物理和机械性能与所用工作条件下的湿度因子无关。
5.含硼聚乙烯板具有化学稳定性,在一定的温度和浓度范围内,能抵抗酸、碱、盐和有机溶剂等多种腐蚀介质的腐蚀。
6.含硼聚乙烯板具有无臭、无毒、无臭、无腐蚀性,具有生理周期和生理适应性。
7.不粘连;
8.当含硼聚乙烯板的分子量超过万时,其脆化温度降至℃,甚至可以在液氮中使用超高分子量聚乙烯(UHMWPE)超高分子量聚乙烯(UHMWPE)的温度可以达到℃以下,且仍具有一定的机械强度含硼UHMWPE板的定义:含硼UHMWPE板是一种新型复合屏蔽材料,由碳化硼粉和铅粉在高速搅拌、捏合、塑化和热压下均匀搅拌而成。
