[0002] Polyurethane material is the abbreviation of polyurethane. Polyurethane is a polymer material with high strength, tear resistance and wear resistance. It is widely used in light industry, chemical industry, electronics and textile because of its excellent performance. , medical, construction, building materials, automobiles, national defense, aerospace, aviation and other fields, in the existing production process of polyurethane, the polyurethane is usually placed in the reaction device for reaction, and a simple stirring rod is used for stirring, but when mixing When there are many materials, there is the problem of uneven and insufficient stirring, especially when the reaction raw materials are agglomerated, the reaction raw materials cannot be dispersed, and the quality of the finished product is low. However, the reaction speed cannot be changed in time according to the reaction, resulting in low reaction efficiency and low quality of the finished product. , and due to the high viscosity of the reaction raw materials, the reaction raw materials are easily attached to the inner wall of the reaction device, so that the reaction raw materials cannot be mixed evenly, and the waste of the reaction raw materials can also be caused
