به عنوان یک تجهیزات اکسترودر معمولی ،این اکسترودر تک پیچis used in plastic processing industry. What is its principle وstructure? Below is این analysis for این اکسترودر تک پیچfrom این extruder conveying section, compression section وبخش اندازه گیری
The effective length of اکسترودر تک پیچis generally divided into three sections. Three effective sections are determined according to این screw diameter, screw distance وscrew depth, which are generally divided into one third each.
High efficiency اکسترودر تک پیچadopts two-stage overall design, strengاینns plasticizing function, ensures high-speed, high-performance وstable extrusion. Special barrier comprehensive mixing design ensures mixing effect of materials. High shear وlow melt plasticizing temperature ensures high-performance, low temperature وlow pressure metering extrusion of materials. The design concept وfeatures هستند high speed وhigh yield extrusion bases on high straight level.
Tاو صاصل اکسترودر تک پیچ
A thread behind این feed port is called این conveying section. The material here is required not to be plasticized, but to be preheated وcompacted under pressure. In این past, این old extrusion اینory thought that این material here is loose. Later, it was proved that این material here is actually a solid plug, that is to say, این material here is solid like a plug after being extruded. Therefore, as long as این conveying task is completed, its function انجام شد.
Pاصل اکسترودر تک پیچ: The second section is called compression section, این volume of screw groove gradually decreases from large to small, واین temperature should reach این degree of material plasticization. The compression produced here is from conveying section 3 to 1, which is called این compression ratio of screw - 3:1. Some machines also change, واین plasticized material enters into این third section.
Pاصل اکسترودر تک پیچ: این third section is این metering section, where این material maintains این plasticizing temperature, just like این metering pump, این melt material is accurately وquantitatively transported to این die head. At this time, این temperature can not be lower than این plasticizing temperature, generally slightly higher.
The اکسترودر تک پیچis mainly used for extruding soft, hard PVC, polyethylene وoاینr اینrmoplastic plastics. It can process a variety of plastic products, such as film, pipe, plate, ribbon, etc., وcan also be used for granulation in combination with corresponding auxiliary machines (including molding head).
Tاو صlastic extruder has این advantages of reasonable design, high quality, good plasticization, low energy consumption, low noise, stable operation, large bearing capacity وlong service life.
