双螺杆挤出机工作原理（Working principle of twin screw extruder） Twin-screw extruder working principle. TXT I wonder how many people are separated or deeply loved. ゝ cry laugh themselves look at themselves. You use invisibility to avoid me, I use stealth to become you! When I have the right to a day, I will kill my dog. The extrusion molding process is the most widely used, most varied, high productivity, high adaptability, wide application and the largest percentage of production. Extrusion molding is a continuous shape of a polymer (or viscous fluid) formed by a certain shape in the extrusion of extruder. Extrusion molding process is suitable for all polymers. Almost all of the thermoplastic plastics can be formed, which can also be used in thermosetting plastics, but only a few thermosetting plastics, such as phenolic. Plastic extruded products include tube, sheet, rod, sheet, film, single wire, wire wrap, various profiles, plastic and other materials complex. At present about 50% thermoplastic plastic products are extruded. Extrusion process are also commonly used in plastics coloring, mixing and plasticizing, granulation and blending modification of plastics, etc., on the basis of the extrusion molding, blow, such as tensile technology, and develop into a blow molding and extrusion stenter extrusion molding products production of hollow blow molding and biaxial tensile film etc. Visible extrusion molding is the most important method in polymer forming. Extrusion equipment has a screw extruder and plunger extruder two kinds, the former for the continuous extrusion, the latter for intermittent extrusion, it is mainly used for high viscosity material forming, such as ptfe, ultra-high molecular weight polyethylene. Screw extruder can be divided into single screw extruder and multi-screw extruder. Single screw extruder is the most basic extruder in production. Twin screw extruder in multi-screw extruder has been developing fastest in recent years. At present, the double screw e
