Description

Technical Field

[0001] The utility model relates to the technical field of mixing and kneading, in particular to raw material pretreatment equipment for PVC sheet production. Background Art

[0002] PVC is polyvinyl chloride. It uses non-crystalline materials as raw materials. It has super high performance in anti-oxidation, strong acid resistance and anti-reduction. It is a very good material, so it is widely used in all walks of life.

[0003] When making PVC sheets, PVC masterbatch, plasticizers, stabilizers or pigments need to be evenly mixed together, then melted by hot melt, and then cooled to form.

The mixing effect of the raw materials within the range of the stirring shaft will be better, while the mixing effect of the raw materials within the range of the stirring shaft will be relatively poor. This results in the final mixing quality of the PVC raw materials being less than ideal, which will in turn affect the final quality of the subsequent PVC sheets. Utility Model Content
