Description

Technical Field

[0001] The utility model relates to the technical field of stirring equipment, in particular to homogenizing stirring equipment for polycarbonate production. Background Art

[0002] Polycarbonate is a high-performance thermoplastic engineering plastic that contains carbonate groups in its molecular chain. It has excellent transparency, high strength, high toughness, impact resistance and high temperature resistance. It is often used to manufacture bulletproof glass, eyeglass lenses, optical media such as CDs and DVDs, medical devices, automotive parts and electronic equipment. In the production process of polycarbonate, stirring is an important step because it helps to ensure that the raw materials are fully mixed, which requires the use of homogenizing and stirring equipment for polycarbonate production;

[0003] However, at present, some homogenizing stirring equipment for polycarbonate production is to set stirring blades in the stirring tank to stir and mix the raw materials in the tank. However, since polycarbonate is a mixture of multiple raw materials, the densities of various raw materials are different. Some raw materials with higher density are easy to accumulate at the bottom of the stirring tank, and it is difficult for the stirring blades to stir the raw materials at the bottom. This may lead to insufficient mixing of the raw materials, forming areas of local uneven concentration, and affecting the final quality of the product. Therefore, a homogenizing stirring equipment for polycarbonate production is proposed. Utility Model Content
