[0002] Degradable plastic is a plastic that has easily dispersed groups, easily broken chemical bonds, and easily transferred atoms or groups introduced into the chemical structure of new materials through new polymer synthesis technology. Under the action of light, mechanical vibration or microorganisms, the molecular chain of this plastic will break and the structure will be destroyed, so that it can be decomposed in nature. It does not pollute the environment, can be recycled and reused, and is light in weight, easy to process, has good packaging performance, and is easy to surface decorate.

[0003] At present, mixing equipment is often needed in the production process of biodegradable plastics.

Therefore, traditional mixers are difficult to solve the problem of material adhesion during the processing of biodegradable plastics. Therefore, there is an urgent need for a mixing equipment for processing biodegradable plastics. Utility Model Content
