Can waste PVC plastic be recycled?
PVC is one of the five general synthetic resins in synthetic materials, and its output ranks second only to polyethylene. At present, China's PVC soft products account for 45% and hard products for 55%, of which the consumption ratio of hard products is increasing year by year. PVC is one of the most widely used plastics in the world. It is widely used in the construction industry, packaging materials, household necessities and automobile industry. Although there have been many debates about whether PVC should be banned due to the pollution of plastics to the environment in the past ten years, the production of PVC is still growing.
At present, the discussion on the impact of PVC on environmental issues is becoming more and more objective, especially because of the depletion of oil resources, PVC has become even more attractive, because compared with this, only half of PVCC synthetic raw materials come from oil, and the other half comes from rich minerals. However, the recovery of PVC and its potential impact on the environment have not been resolved, and the use of PVC is still limited in many occasions. Therefore, it is still necessary to pay attention to the application development and recovery of PVC.
At present, the recycling methods of PVC plastics mainly include:
Incineration or landfill
Waste plastics as fuel heat energy
Waste plastics replace coke as reducing agent in ironmaking
Production of fuel oil by cracking
Polyvinyl chloride Resin Powder SG-5 type qilu
