Thermosensitive material is a kind of material with poor thermal stability. It is sensitive to temperature and easy to decompose, degrade and discolor at high temperature. When decomposed, it releases corrosive or toxic gases. It is necessary to strictly control the processing temperature (e.g. polyvinyl chloride, polyformaldehyde, EVA and copolymer of vinyl chloride, etc.).
Because of its good insulation and stable chemical properties, this kind of material is widely used in the fields of electronics, electrical appliances, automobiles, transportation, aerospace manufacturing, national defense and military industry. In the production process of twin screw, high speed shear and high pressure will lead to the increase of local temperature of materials, which directly affects the processing of heat sensitive materials.
Through nearly 30 years of research and application, Nanjing KY Chemical Machinery Co., Ltd. has improved the twin-screw machine model, developed special screw components and new equipment, summarized the characteristics of screw assembly, and developed a set of screw components, screw assembly and equipment for processing thermal sensitive materials. It can effectively control the temperature change in the process of heat-sensitive material processing, and provide customers with a set of high-quality special solutions.
