Existing problems and solutions of PE and PPR pipeline extrusion 1. The basic principle of plastic extrusion The plastics processing industry is a very comprehensive technology-based industry. It involves polymer chemistry, polymer physics, interface theory, plastic machinery, plastic processing molds, formula design principles and process control. Extrusion theory mainly studies the movem
PVC pipe use: mainly suitable for housing electric wire pipes and drainage pipes. hundred Advantages and disadvantages: The main advantages are high cost performance, simple construction, light weight, and less construction trouble. The disadvantage is that the thickness is relatively thin, and the performance of pressure resistance and high temperature resistance is poor. PPR pipeline use: main
The ppr tube is the most ideal hot water supply pipeline for modern copy (modern decoration effect diagram). It is because the ppr tube has good heat resistance. The long-term use temperature can reach 75 °. There is no problem. 95.ppr tube insulation effect is also good. 2. PPR pipe is smooth in one hundred pipes, and no other particles can be touched. This advantage makes the pipeline resistanc
PPR is the abbreviation of tripropylene polypropylene, also known as random copolymer polypropylene tube. It adopts the method of thermal welding, has special welding and cutting tools, and has high plasticity. The price is also very economical. With the addition of an insulation layer, the insulation performance is better, and the pipe wall is also very smooth, excluding the joints of the inner a
In-depth understanding of the problems encountered in the extrusion process during the production of silicon core tubes In the production of silicon tubes, what problems are often encountered in the process of tube extrusion and how to solve these problems? These conditions are generally due to the inexperience of operators in the process and machine operation, which often causes the tube to ha
The production of HDPE silicon core tube finished products is the most important link in the production process of HDPE silicon core tube, and is also a link with more problems. HDPE silicon core tube professional manufacturer Hubei Liangcheng Plastic Industry has summarized many years of production experience and will The common problems and solutions are listed below. I hope to help my friend
1. Performance characteristics The silicon core layer on the inner wall is a solid, permanent lubricant; the silicon core layer on the inner wall is squeezed into the high-density polyethylene pipe wall synchronously, and the entire inner wall of the pipe is evenly distributed, without peeling, detaching, and The silicon tube has the same life; the silicon core layer on the inner wall has the s
Precautions for silicon core tube construction 1. When the silicon core tube is unloaded, the operator will gently lift it into the tube trench and tube box every 10 meters. It must not rub against the ground, keep the pipeline straight, without twisting, twisting and other phenomena. The silicon core tube should be placed in an orderly manner in the trench, and the silicon core tube should be st
