设备简易塑胶零件加工 ABS塑料件加工怎样避免异味的产生?

严格控制添加剂使用

设备简易塑胶零件加工生产过程中所用到的催化剂叔胺常常会带来很强的气味,同时还会在汽车内窗上结雾,我们可以找到这些胺类的代替物运用多羟基化合物,多羟基化合物不仅是聚氨酯分子链的成分,而且也相同具有催化活性,一些多羟基化合物乃至能够替代一半的叔胺催化剂,这样一来,注塑加工产品气味就变淡了。

很多塑料中,特别是在聚氯乙烯、苯乙烯、聚乙酸乙酯和丙烯酸酯等,残留的微量单体会发生难闻的气味.选用单体残留量很少的树脂即可消除那些气味,如果选用自无气味的树脂效果比较好。在聚合物中如果填充少数的沸石,即可起到去掉资料气味的效果.沸石具有很多的结晶空泛,这些空泛能够捕捉那些具有气味的气体小分子。
