[0002] Calcium zinc stabilizer is synthesized by special composite process with calcium salt, zinc salt, lubricant, antioxidant as main components. It can not only replace toxic stabilizers such as lead cadmium salts and organic tin, but also has quite good thermal stability, light stability, transparency and tinting strength. Practice has proved that in PVC resin products, it has good processing performance and thermal stability equivalent to lead salt stabilizer. It is a good non-toxic stabilizer.

[0003] Calcium zinc stabilizer is mainly composed of calcium salt, zinc salt and lubricant. When processing it, the components need to be mixed.

Therefore, it is necessary to provide a calcium zinc stabilizer raw material closed mixing device, which adopts a fully enclosed mixing method to prevent moist air from entering and avoid the phenomenon of material flying.
