[0002] Ultra-high molecular weight polyethylene (UHMWPE) is a polymer material with excellent performance, which is widely used in machinery, chemical industry, medical and other fields. The main methods for preparing ultra-high molecular weight polyethylene include solution method, melting method and radiation method, among which the solution method is a commonly used method. Its principle is to mix ultra-high molecular weight polyethylene powder with solvent, and obtain ultra-high molecular weight polyethylene solution through stirring, heating, evaporation and other processes, and then obtain ultra-high molecular weight polyethylene products through extrusion, cooling, cutting and other processes. One of the key processes for preparing ultra-high molecular weight polyethylene by solution method is stirring. The purpose of stirring is to fully mix ultra-high molecular weight polyethylene powder with solvent to form a uniform solution, which is also conducive to the evaporation of solvent and the flow of solution. The stirring effect directly affects the quality and stability of ultra-high molecular weight polyethylene solution, and then affects the performance and quality of ultra-high molecular weight polyethylene products.

This makes it impossible to remove the agitator body, and it is difficult for the staff to take out the mixed solution in the agitator body, resulting in inconvenience in use. In view of this, we propose ultra-high molecular polyethylene production equipment. Utility Model Content
