补充资料:隔离膜
分子式:
CAS号:

性质:防止预浸料毛坯成型固化时粘于其他材料上的材料。一般为含卤元素的树脂薄膜,如聚四氟乙烯玻璃布、能在成型温度下使用的防粘塑料膜等。隔离薄膜分有孔和无孔两种在热压罐成型工艺中作为真空封装的材料使用,无孔隔离膜置于模压板与吸附胶材料之间,其作用为防止吸胶材料中的树脂粘于模压板上。一般厚度为0.025mm。有孔隔离膜置于复合材料毛坯表面材料与吸胶材料之间,其作用是让气体通过而限制一定量的树脂通过,并且防止黏附于上下两种材料之上。用聚四氟乙烯制造的薄膜分为两种,一种厚度为0.025mm,其表面每平方寸(11cm2)上有14个孔,允许10%的树脂通过。另一种厚度也为5mm,表面上有小孔,允许气体通过和1%~3%树脂通过。
