How to plastic recycling
The regeneration methods after plastic recovery include melting regeneration, thermal cracking, energy recovery, recovery of chemical raw materials and other methods.
(1) Melting regeneration melting regeneration is a method of reheating and plasticizing waste plastics. Shenyang material recycling company is divided from the sources of waste plastics. This method can be divided into two categories: one is the recycling of clean waste plastics recovered from the leftover materials of resin plants and processing plants; The second is the recycling of various plastic products mixed together after use. The former is called pure regeneration, which can produce plastic products with good performance; The latter is called composite regeneration, which can only prepare plastic products with relatively poor performance requirements, and the recycling process is more complex.
(2) Pyrolysis pyrolysis method is a method of preparing combustion feed oil and fuel gas from selected waste plastics by pyrolysis.
(3) Energy recovery energy recovery is a method of using the heat generated by the combustion of waste plastics.
(4) Recycled chemical raw materials, some kinds of plastics, and polyurethane can be hydrolyzed to obtain raw material monomers during synthesis. This is a method of recycling waste plastics into chemical raw materials by chemical decomposition.
