Ang Prinsipyo ng Temperatura ng Twin Screw Extruder

Ang Ningbo Fangli Technology Co., Ltd. ay isangtagagawa ng mekanikal na kagamitanna may halos 30 taong karanasan ngplastic pipe extrusion equipment, bagong proteksyon sa kapaligiran at mga bagong materyales na kagamitan. Mula nang itatag ang Fangli ay binuo batay sa mga kahilingan ng gumagamit. Sa pamamagitan ng patuloy na pagpapabuti, independiyenteng R&D sa pangunahing teknolohiya at panunaw at pagsipsip ng advanced na teknolohiya at iba pang paraan, nakabuo kamiPVC pipe extrusion line, PP-R pipe extrusion line, PE water supply / gas pipe extrusion line, na inirekomenda ng Chinese Ministry of Construction na palitan ang mga imported na produkto. Nakuha namin ang pamagat ng "Unang-klase na Brand sa Lalawigan ng Zhejiang".

Extrudable plastics are thermoplastics, which melt when heated and solidify again when cooled. Therefore, heat is required during the extrusion process to ensure that the plastic can reach the melting temperature. So where does the heat of melting plastic come from? First of all, the weighbridge feed preheating and the barrel/mold heater may work and are very important at startup. In addition, the motor inputs energy, that is, the frictional heat generated in the barrel when the motor overcomes the resistance of the viscous melt to rotate the screw. The most important heat source for all plastics, except of course for small systems, low-speed screws, high melt temperature plastics and extrusion coating applications. In operation, it is important to realize that the barrel heater is not actually the main heat source, and its effect on extrusion may be smaller than we expected. The temperature of the rear cylinder is more important because it affects the speed of solids in the toothing or feed. Generally speaking, in addition to being used for a specific purpose (such as glazing, fluid distribution or pressure control), the temperature of the die and mold should reach or be close to the temperature required by the melt.
