它本色重量很轻,有良好的刚性,通过改性可以达到很多种物理特性,一般的塑胶原料的来源都是以石油而提炼出来的化学品。是经过聚合反应得到的高分子树脂。加强工程塑料防火的添加剂有:卤素及非卤素(磷酸脂)防火剂。化学性能增强 :安定剂、抗氧化剂、表面处理改质剂。物理性能增强可添加::玻璃纤维、碳纤维、矿物质等 …。
原料与水口:
原料就是直接从石油里面提炼出来从来没加工的料,水口是经过一次高温成型的塑料,原料的化学性能稳定,物理性能良好,水口的物理性比原料要差的多,容易脆,比较易开裂,韧性远比不上原料,它的成型次数越多它的料性就越脆。原料与水口的分辨:从颜色上来区分水口料比例大的产品易发黄发黑。
水口料做不出透明产品,做普通产品水口料的比率不能大于35%,要求低的产品水口料可以到达。其次水口料做大产品断口位发黑。
EVA树脂的特点:
是具有良好的柔软性,橡胶般的弹性,在-50℃下仍能够具有较好的可挠性,透明性和表面光泽性好,化学稳定性良好,抗老化和耐臭氧强度好,无毒性。与填料的掺混性好,着色和成型加工性好。EVA树脂用途很广。一般情况下,乙酸乙烯含量在5%以下的EVA,其主要产品是薄膜、电线电缆、LDPE改性剂、胶粘剂等
