            Application of plastic nylon rod in transformer

            Release date:2018-12-20 17:12:09
            Application of plastic nylon rods in transformers: Transformers are important electrical components that function to change voltage, transfer voltage, transfer power, and impedance matching. The plastic nylon rod is characterized by good heat resistance, good solvent resistance and high strength; it can be used as a skeleton and a wiring board in a transformer.
            In recent years, with the advent of new types of new high temperature engineering plastics, the application of plastic nylon rods in transformers has been reduced, and the application of new materials such as PBT and PPS has become more and more widespread.
            Plastic nylon rod (tough rod)
             
            Plastic nylon rod Rockwell hardness: The plastic nylon rod has a Rockwell hardness of 23 ° C and a dry environment of 119 HRB.
            Brief introduction of production process of plastic nylon rod: 1. Equipment: plastic extruder 2. Material: Extrusion of plastic nylon rod is a difficult variety in plastic products; the selection of materials generally chooses the grade with viscosity above 3.0, the lower the viscosity The more difficult the extrusion is, the more mature the mold requirements are. According to the length-to-diameter ratio of the screw, the raw materials with different particle sizes are selected. 3. The mold: the structure of the machine head is not much different from that of the ordinary plastic machine head, but the pressure is relatively high. Preparation: Because nylon has strong hygroscopicity, it must be dried before processing to ensure the moisture content is below 0.3%. 5. Preheating Our company insists on creating first-class technology. Satisfy customers and ensure the quality of the brand. Welcome calls to discuss cooperation! The company's main products: plastic nylon rod, nylon tube, nylon board, polyoxymethylene (POM) rod, polyoxymethylene (POM) sheet, ultra-high molecular polyethylene (UHMW-PE) sheet, MC nylon tube sheet, polypropylene, Bars made of polyethylene, polyoxymethylene, polycarbonate, ABS, polytetrafluoroethylene rods, tubes, plates, films and raw materials; ultra-high molecular polyethylene sheets and various rubber sealing products.
