Recycled polyvinyl chloride has the characteristics of high mechanical strength, light weight, good insulation, high strength, easy processing, and corrosion resistance. It has a wide range of applications in construction, plumbing, electronic appliances, automotive industry, packaging and other fields, especially in the field of pipes. PVC plastic pipes made of PVC recycled materials are mainly used in the construction industry to replace traditional cast iron pipes as indoor and outdoor drainage pipes, wire threading pipes, and communication cable protection pipes.
Precautions when using PVC regeneration pipes
The performance of recycled plastic pipes has decreased to varying degrees, mainly due to photoaging, oxidative aging and thermal aging. The degree of reduction mainly depends on the age and environment of use.
Waste edges and waste produced in the production process of the molding factory. Its performance of recycled materials decreases very little, and it can almost be used as new materials; for indoor products with short life, the performance of recycled materials does not change much; for outdoor products with long life and harsh environments, such as pressure, electric field, Chemical media, etc., have poor performance and cannot even be recycled.
PVC undergoes thermal aging degradation during the regeneration process, and the color of the recycled material changes from light to dark. It is not recommended to mix recycled materials with industrial plastic products or use them directly.
