颗粒化之前

在开始塑料颗粒化之前，有必要明确废塑料的原材料。

Why should waste plastics be sorted? Many novices do not know that plastic is only a general name, and different materials have very different properties, uses, and prices.

The value depends not only on whether it is waste plastic raw material or recycled granules, but also on the specific type of plastic, its cleanliness, color, and purity. Proper sorting helps recycling work more efficiently and can also improve the final selling price.

废塑料分类最重要的部分是不同的回收流程，包括造粒机类型和工作温度。

塑料的材料：

  • 聚丙烯（PP）：编织袋、水果篮等。
  • 聚乙烯（PE）：温室膜、垃圾袋等。
  • ABS：电器外壳、保险杠等。
  • PET：矿泉水瓶、饮料瓶等。
  • PVC：电线护套，包装箱等。
  • PC：灯罩，光盘等。
  • PA：轮子等。
