1. Granulation after volume reduction: Polystyrene foam can be melt-extruded and pelletized to make recycled pellets, but it is bulky and inconvenient to transport. Usually, the volume needs to be reduced before recycling. Methods include mechanical method, solvent method and heating method.
2. Used as filler after crushing: Polystyrene foam plastic products can be used as filler after crushing to make various products.
① Re-molding into foamed plastic products
②Concrete composite board products
③Gypsum sandwich brick
④Used as asphalt intensifier
⑤Used as soil modifier
3. Pyrolysis for oil production or recovery of styrene: The equipment for the method for cracking waste polystyrene foamed plastics for oil production is as follows:
Pretreatment of waste polystyrene foam, heat treatment, volume reduction, catalytic cracking and rectification of styrene
4. Others: waste polystyrene foam can be used to make coatings and adhesives, etc.
①Coating: Expandable polystyrene foam can be crushed and added with appropriate solvent to make paint.
Polystyrene foam is useful for molding polystyrene beads. Foam plastic used for packaging of household appliances or frozen food; there are also a few instant noodle bowls made of expandable polystyrene beads by injection molding. These plastic products are huge in size and large in tuition and fees, and their recycling is particularly valued in China.
