• What are the types of Jiangmen engineering plastics

    Engineering plastics have the characteristics of high rigidity, small creep, high mechanical strength, good heat resistance and good electrical insulation, which make it can be used in harsh chemical and physical environment for a long time, and can replace metal as engineering structural materials. With the development of technology, the application of engineering plastics has been extended to cars, home appliances, aviation, sports, electronics, construction and other fields. PA is a kind of engineering plastics with excellent mechanical properties and high mechanical properties. It can be obviously improved by strengthening and flame retardant modification

  • What are the basic properties of Jiangmen engineering plastics

    How to define engineering plastics? Engineering plastics generally refer to the plastic materials which can be used as structural materials to accept mechanical stress and can be used in a wide range of temperature planning and harsh chemical and physical environment. Engineering plastics can be divided into general engineering plastics and special engineering plastics. General engineering plastics usually refer to five kinds of plastics which have been industrialized and widely used, namely polyamide (nylon, PA), polycarbonate (polycarbonate, PC), Polyoxymethylene (POM), polyester (PBT) and polyphenylene oxide (PPO). And special engineering plastics refer to more excellent functions

  • Treatment method of mould scale of plastic products in Jiangmen project

    It is necessary to strengthen the maintenance of the mould when we can't eliminate the mould scale by various methods. Mold scale on the surface of the mold is relatively simple to remove at the initial stage, so it is necessary to clean and maintain the mold cavity and exhaust channel on time (for example, after each batch of molding production). If the mould is not maintained for a long time, it is not simple and time-consuming to remove the mould scale after forming a thicker layer. Injection mold maintenance and maintenance of the spray used are mainly: mold release agent, rust inhibitor, thimble oil, gel remover, mold cleaning agent, etc. The chemical composition of mold scale is very complex, so it is necessary to use and check new methods to eliminate the scale, such as general solvents and various types of scale

  • What is the function of Jiangmen engineering plastics

    Engineering plastics can be used as engineering materials and substitute for metals. Excellent mechanical function, heat resistance and dimensional stability are required. There are polyoxymethylene, polyamide, polycarbonate, ABS plastics and so on. For example, the mechanical and mechanical functions of polyoxymethylene are similar to those of copper and zinc. If it is used as a bearing on a car, its service life is twice as long as that of metal. It can also be used as other spare parts. Polycarbonate can not only replace some metals, but also replace glass, wood and alloy. It can be used as the shell of various instruments, bicycle frame, windshield and furniture of aircraft. (1) polyamide (nylon) polyamide is an applied thermoplastic

  • What is the use of modified engineering plastics

    Modified plastics refer to the plastic products which are processed by filling, blending and strengthening on the basis of general plastics and engineering plastics to improve the flame retardancy, strength, impact resistance and resistance. The main uses of modified engineering plastics: 1. The market demand of high strength and high rigidity nylon is increasing. New reinforced materials such as inorganic whiskers are reinforced. Carbon fiber reinforced PA has become an important variety. It is mainly used in automobile engine parts, mechanical parts and aviation equipment parts. 2. Nylon alloying will become the mainstream of modified engineering plastics. Nylon alloying is to achieve high performance of nylon
