Description

Technical Field

[0001] The utility model relates to PVC lubricant granulation equipment, belonging to the technical field of PVC lubricant granulation. Background Art

[0002] Due to the inherent molecular structure of polyvinyl chloride (PVC), its chemical properties suffer from numerous drawbacks when directly extruded as a raw material to produce plastic products, particularly poor light and heat stability. Without a heat stabilizer, PVC begins to decompose at 100°C. Thermal decomposition releases toxic hydrogen chloride gas, causing discoloration. It also undergoes photooxidative decomposition in the presence of ultraviolet rays and oxygen in sunlight, reducing its flexibility and making it brittle. This clearly fails to meet the requirements for PVC products in both domestic and industrial use. Therefore, during the PVC molding process, a certain amount of PVC lubricant is often added to the PVC resin powder to modify the material's chemical properties.

[0003] PVC lubricant is usually in granular form and is formed by solidifying a liquid lubricant after cooling. In the prior art, the liquid lubricant is usually cooled by air cooling, but the cooling effect is poor. The particles after cooling tend to stick together or even become hardened.

[0004] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content
