Quality defects of PPR pipe extrusion and the solutions PP-R (Poly Propylene Random) pipe, that is, random copolymer polypropylene pipe, is a new type of water pipe material commonly used in developed countries today. PP-R pipeline has been used in Europe for more than 10 years. Due to its excellent performance, its market share has been far ahead of other plastic water pipe materials in recent y
The longer the use of PPR water pipes, the greater the "poisonousness". In fact, many people do not know that they have already taken the trick! Now many people like to decorate the house according to their own preferences. How can they choose the right pipe within a reasonable budget? Now I will introduce you to the ppr water pipe. PPR's water pipes can affect household water use issues and
PPR pipe is also called three-type polypropylene pipe and random copolymer polypropylene. The random copolymer polypropylene can be extruded into pipe material and can also be injected into pipe fittings. The random copolymer of polypropylene is also a kind of polypropylene. The basic structure of its polymer chain is modified by adding different kinds of monomer molecules. Ethylene is the most
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
