1. The purchase of plastic classification, plastic categories, the general waste recycling station has done a rough sorting, but to ensure the quality of particles should be further selected.

2. Some waste plastics in the initial wash contain a particularly large amount of impurities, such as polypropylene woven bags used in packaging cement, polyethylene agricultural mulch, garbage convenient bags, edible fungus bags, etc., in order to effectively clean up impurities and reduce water consumption, more pre-washing is used.

3. Crushing and cleaning

4. Rinsing (fine washing)

5. Dehydration (depending on whether the situation requires or not)

6. Plasticizing extrusion, drawing, cutting, packaging.

Common plastic particles are general plastics, engineering plastics, and special plastics.

General plastics: polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, polyurethane, etc.

Engineering plastics: nylon, polytetrafluoroethylene, polyformaldehyde, polycarbon silicone, etc.

Specialty plastics: thermosetting plastics, functional polymer plastics, such as artificial kidneys.
