Description

Technical Field

[0001] The utility model relates to the technical field of PBAT plastics, and in particular to a production device for PBAT. Background Art

[0002] PBAT, short for polybutylene terephthalate adipate (PBAT), is a fully biodegradable polyester. PBAT products offer excellent overall performance and a reasonable price-performance ratio. They can be used in packaging, tableware, cosmetic and pharmaceutical bottles, disposable medical supplies, agricultural films, pesticide and fertilizer slow-release materials, and biomedical polymers. Its wide range of applications and promising prospects for widespread adoption have made it a leader among biodegradable plastic materials.

[0003] However, in the current PBAT production and mixing process, the raw materials need to be weighed in advance before being fed, which greatly reduces work efficiency. In addition, due to its own easy coagulation during the static process, the slurry of PBAT easily sticks to the inner wall during the mixing process. If this situation is not cleaned up in time, it will affect the subsequent production process. Utility Model Content
