PBT is widely applied to the fields of automobiles, mechanical equipment, precision instrument parts, electronic and electric appliances, textiles and the like. Most of PBT resin is processed into a compound for use, and can obtain good comprehensive properties such as heat resistance, flame retardance, electric insulation and the like and good processability by being blended with other resin after being modified by various additives. The method is widely applied to industries such as electric appliances, automobiles, airplane manufacturing, communication, household appliances, transportation and the like. For example, PBT is modified by glass fiber and the like, and can be used for manufacturing electronic parts which require high dimensional stability under the working condition of high temperature for a long time. The PBT has high breakdown voltage, is suitable for manufacturing high-voltage resistant parts, and is suitable for injection processing of electrical parts with complex structures, such as sockets of integrated circuits, printed circuit boards, computer keyboards, electrical switches, fuses, temperature control switches, protectors and the like, due to good fluidity of the molten state of the PBT. Automobile bumpers, carburetors, spark plugs, fuel supply system components, igniters, and the like. In the communication field, PBT is widely used for integrated modules, wiring boards, electric tools and the like of program-controlled telephones.
Before the PBT plastic particles are cut into particles, the strip PBT plastic guided out from the compression roller needs to be fully cooled, and then the particles can be cut into particles. In the past, before the strip-shaped PBT plastic is cooled, the temperature of the strip-shaped PBT plastic is higher just after the strip-shaped PBT plastic comes out from a compression roller, and the strip-shaped PBT plastic is directly exposed in air, so that the PBT plastic is easy to react with oxygen in the air to generate an oxidation film, and the quality of the PBT plastic is reduced, and therefore a gradual cooling device for PBT particles for automobile injection molding accessories is urgently needed to solve the problems.
