Description

Technical Field

[0001] The utility model relates to the technical field of polyvinyl chloride production and processing, and particularly relates to an SPVC powder filtering and conveying system. Background Art

[0002] SPVC is a polymer formed by the free radical polymerization mechanism of vinyl chloride monomer (VCM) under the action of initiators such as peroxides and azo compounds or under the action of light and heat. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively called vinyl chloride resins.

[0003] The main differences between SPVC and PVC lie in their production methods and application fields.
