একক স্ক্রু এক্সট্রুডারের নীতি এবং প্রয়োগ

2021-05-12

একটি সাধারণ এক্সট্রুডার সরঞ্জাম হিসাবে,দ্য একক স্ক্রু এক্সট্রুডারis used in plastic processing industry. What is its principle এবংstructure? Below is দ্য analysis for দ্য একক স্ক্রু এক্সট্রুডারfrom দ্য extruder conveying section, compression section এবংপরিমাপ বিভাগ।

The effective length of একক স্ক্রু এক্সট্রুডারis generally divided into three sections. Three effective sections are determined according to দ্য screw diameter, screw distance এবংscrew depth, which are generally divided into one third each.

High efficiency একক স্ক্রু এক্সট্রুডারadopts two-stage overall design, strengদ্যns plasticizing function, ensures high-speed, high-performance এবংstable extrusion. Special barrier comprehensive mixing design ensures mixing effect of materials. High shear এবংlow melt plasticizing temperature ensures high-performance, low temperature এবংlow pressure metering extrusion of materials. The design concept এবংfeatures সে গুলো high speed এবংhigh yield extrusion bases on high straight level.

A thread behind দ্য feed port is called দ্য conveying section. The material here is required not to be plasticized, but to be preheated এবংcompacted under pressure. In দ্য past, দ্য old extrusion দ্যory thought that দ্য material here is loose. Later, it was proved that দ্য material here is actually a solid plug, that is to say, দ্য material here is solid like a plug after being extruded. Therefore, as long as দ্য conveying task is completed, its function সমাপ্ত.

Pএকক স্ক্রু এক্সট্রুডারের নীতি: The second section is called compression section, দ্য volume of screw groove gradually decreases from large to small, এবংদ্য temperature should reach দ্য degree of material plasticization. The compression produced here is from conveying section 3 to 1, which is called দ্য compression ratio of screw - 3:1. Some machines also change, এবংদ্য plasticized material enters into দ্য third section.

Pএকক স্ক্রু এক্সট্রুডারের নীতি: দ্য third section is দ্য metering section, where দ্য material maintains দ্য plasticizing temperature, just like দ্য metering pump, দ্য melt material is accurately এবংquantitatively transported to দ্য die head. At this time, দ্য temperature can not be lower than দ্য plasticizing temperature, generally slightly higher.

The একক স্ক্রু এক্সট্রুডারis mainly used for extruding soft, hard PVC, polyethylene এবংoদ্যr দ্যrmoplastic plastics. It can process a variety of plastic products, such as film, pipe, plate, ribbon, etc., এবংcan also be used for granulation in combination with corresponding auxiliary machines (including molding head).

Tতিনি পিlastic extruder has দ্য advantages of reasonable design, high quality, good plasticization, low energy consumption, low noise, stable operation, large bearing capacity এবংlong service life.
