The production process of recycled plastic pellets is complicated. Today we will take a look at the production process of recycled plastic pellets.
The first step is to sort out the plastics that have been purchased, and there are many kinds of plastics. The general waste recycling station has already done a general sorting, but the quality of the particles should be further selected.
In the second step, some waste plastics have a particularly large amount of impurities, such as polypropylene woven bags for packaging cement, polyethylene agricultural mulch, garbage convenient bags, edible fungus bags, etc., in order to effectively clean up impurities and reduce water consumption. Use the pre-stage coarse (primary) wash.
The third step, pulverizing and cleaning, such as a polystyrene food container, is a light-weight, impurity-containing package that needs to be washed and compressed, and the compacted foam blocks can be sold at a good price.
The fourth step, dehydration, cleaning the polystyrene waste peers need to be dehydrated, so that the material is kept dry, which is conducive to the next step of production.
The fifth step is plasticizing extrusion, drawing, pelletizing and packaging.
Common plastic granules are general-purpose plastics, engineering plastics, and special plastics.
General purpose plastics: polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, polyurethane, etc.;
Engineering plastics: nylon, polytetrafluoroethylene, polyoxymethylene, polycarbosilicon, etc.;
Special plastics: thermosetting plastics, functional polymer plastics, such as artificial kidneys.
Use of recycled plastic pellets:
In daily life, recycled pellets can be used to make various plastic bags, barrels, pots, toys, furniture, stationery and other living utensils and various plastic products.
In the garment industry: recycled pellets can be used to make garments, ties, buttons, zippers.
Building materials: Recycled pellets can be used to make a variety of building components, construction tools, plastic doors and windows, plaster buckets…
