  • 六种再生塑料的工艺流程一
    一、再生低密度聚乙烯(LDPE)工艺流程
    LDPE,学名高压聚乙烯,它一般是指塑料包装膜。如:编织袋内衬膜、食品包装膜、日用品包装膜、大棚膜。这些膜大部分是本色,也有淡蓝色、黑色,在回收前最好把色样分开。不能把低压膜,PP膜放在一起,更不能把OPP和PVC膜放进去。对LDPE的回收并加以再次利用,就是再生LDPE工艺流程。
    整个再生LDPE工艺流程主要有四道工序:
    1.粉碎工序。带水粉碎冲洗效果则更好。由于一些好的高压膜如果保持足够的清洁,无须添加新料就可以重新吹膜。所以在粉碎过程中要注意清洁,当粉碎料流到水槽后最好再次滚动,目的进一步冲洗清洁点。
    2.干燥工序。一般是到甩干机把余水甩干,如有条件就进行晒干,这样可以节约电费,提高质量,当然要注意防止材料在晒干中的二次污染。
    3.造粒工序。由专用挤出机造出的颗粒,有二种基本用途:再次吹塑膜和注塑。在60到80目的过滤网中出来的材料可以再次吹塑;在40到60目的过滤网中出来的材料可以满足注塑的质量要求。一般来说高压料再次吹膜,好的吹本色差一点吹黑膜和垃圾袋,做注塑料后的价格则更低。
    4.切粒工序,一般是冷水切粒。这道工序必须注意包装时区分标号。一种吹塑用,一种注塑用,以免搞错。另外,吹塑用的包装袋一定要外袋加内衬袋以免二次污染。
