Description

technical field

[0001] The invention relates to the technical field of foamed polyvinyl chloride, in particular to a lightweight and high-strength polyvinyl chloride foamed pipe. Background technique

[0002] The pipeline that conveys gas in the exhaust equipment is called the air duct, which connects various equipment or components in the system into a whole. Ducts are usually made of a smooth surface material such as polyvinyl chloride pipe. Polyvinyl chloride is one of the five general-purpose plastics and is widely used in many industries such as building materials and packaging. Polyvinyl chloride foam materials are more popular due to their light weight, heat insulation, sound insulation, high specific strength, and insulation. However, while the cost of foam materials is reduced, the mechanical properties are reduced, which greatly limits the use of PVC. Application of foam materials. In "Research on Polyvinyl Chloride-Montmorillonite Foamed Composite Materials", q...
