Mixed plastic can be generated from the crushed electric appliance, cars and electronic toys after removed the metals, such as PET/PVC mixture, ABS/PVC mixture, ABS/PS/sinking PP mixture, ABS/PA mixture, etc. The mixed plastic can be recycled and made new products. Today DOING company will introduce common separation methods for recycling different types of plastic from mixed plastics.
Different kinds of waste mixed plastic
Common separation methods for recycling any three kinds of plastic from mixed plastics:
The mixed plastic separation machine can separate any three kinds of plastic mixed together, such as conventional PET / PVC, ABS / PS, PC / PA, etc. The mixed plastic separation machine separate different types of plastic from mixed plastics through shredding, drying, and electrostatic separation. The dried plastic can be sorted in a closed high voltage electric field according to different conductivity. The electrical properties generated by the high-voltage electric field attract plastics of different electrical properties. According to the principle that the same electrical properties are mutually exclusive and different electrical properties are attracted to each other, different electrical plastics are completely separated.

Common separation methods for recycling more than three kinds of plastic from mixed plastics:
But if there are more plastics to be processed, plastics with similar charge will be affected each other, it is difficult to identify the sorting, so the sorting effect will also be poor, so you need to match the equipment according to the type of raw materials. A variety of plastics can be sorted by means of water separation method. The low-density plastics are first separated by the water separation method and sieved to three mixed plastics, which can then be sorted by the mixed plastic separator machine. Examples are as follows.
Common types of plastics are divided into PET, PVC, ABS, PE, PP and other plastics. Taking this as an example, before soaking through the mixed plastic separation machine, we first soaked the five mixed plastics with clean water. At this time, the PP and PE plastics with low density will float on the surface of the water to screen out the PP and PE. The sorted PP and PE can be sorted again with brine. After clearing water, the remaining three PET, PVC, and ABS plastics can be directly sorted by mixed plastic separator machine. In a closed high-voltage electric field, the plastics are sorted according to the charge ability of the plastics. The separation rate of mixed plastic separator machine could reach to 99%.
