Description

Technical Field

[0001] The utility model relates to the technical field of PVC film processing, in particular to high-speed mixing equipment for processing PVC film. Background Art

[0002] The main component of PVC is polyvinyl chloride, which is slightly yellow and translucent and shiny. Its transparency is better than polyethylene and polypropylene, but worse than polystyrene. Depending on the amount of additives used, it is divided into soft and hard polyvinyl chloride. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than low-density polyethylene, but lower than polypropylene, and whitening will occur at the bends. When producing PVC film, various raw materials need to be mixed and stirred, because mixing equipment is needed to process its processing materials.

[0003] At present, many raw materials for making PVC films are treated as garbage due to elimination, but these materials can be recycled and reprocessed to generate materials for making PVC films. When using existing PVC film material mixing equipment, most of them mix various new materials to generate raw materials for making PVC films, which is costly and not conducive to long-term production. The waste PVC materials eliminated from the market are not fully utilized, resulting in a waste of resources. When mixing the materials, a little additive liquid needs to be blended to meet the mixing requirements. However, after the additive liquid is fused with the materials, it will produce viscosity, and when mixed and stirred, it will stick to the inner wall of the barrel. Utility Model Content
