不同塑料薄膜的回收方法

不同材料的塑料薄膜片的加工方法略有不同，但大多数都需要以下步骤。

First of all, the raw material needs to be crushed and washed easily by a crashing and cleaning machine, it is the first step in the plastic film recycling line, then they will be washed thoroughly in a sink.

After that, the wet plastic film sheet will be dehydrated and will be melted as a mushy shape with electromagnetic heating, long strips will be created by the plastic granulator machine, then those long strips will be cooled in a cold water sink, at this moment, they will be cut by the pellet cutting machine, at last, the pellets will be stored in the storage bin.

Due to the characteristics of PVC material, it is best not to wash it in the process of recycling PVC plastic film. If a water washing step is necessary, the raw materials must be dried. And in the processing process, chemical ingredients need to be added.

Generally, the quality of plastic particles is related to the water content of raw materials. Too much water content will seriously affect the quality of plastic particles.

PE塑料薄膜回收生产线

有一种特殊类型的PE塑料薄膜，即保鲜膜。在超市中，冷冻食品或新鲜蔬菜的包装通常会覆盖塑料薄膜。然而，这种保鲜膜通常会贴上标签。这时，需要一个纸塑分离器来分离标签纸和保鲜膜。
