basic Introduction of ppr pipe production processIntroduction of ppr pipe production process
PPR pipe is a new type of pipe. Compared with traditional pipe, it has outstanding advantages, simple production and economical price. It has a wide range of uses in our daily life. However, when it comes to ppr pipe, many people may not understand it. Today , I will bring you to know this kind of pipe, for you to introduce in detail what is ppr pipe and ppr pipe production process.
What is ppr pipe?
PPR pipe refers to random copolymer polypropylene pipe. This kind of pipe is made by thermal fusion welding technology. The inner wall is smooth and it is not easy to collect dirt. With the addition of insulation layer, the insulation effect is obvious, the performance is good, the corrosion resistance, and the safety during use In addition, the price of the pipe is moderate and the ppr pipe is widely used in our daily life.
PPR pipes have stable performance, safety and reliability, and long service life. They have played a huge role in drainage, gas transportation, agricultural irrigation, cable protection and industrial fluid transportation. PPR pipes have played a major role in urban reconstruction and expansion in recent years. Important role, with the continuous expansion of market demand, the development prospects of ppr pipes are very good.
Ppr pipe production process
The first step: according to the use environment and characteristic requirements, choose the special material for making ppr resin, and then choose various additives according to the requirements of the manufacturing process. The role of the additive is to improve the performance of the pipe, improve the manufacturing process, or in some places Direct replacement of raw materials to play a role and save raw materials, these make the production of pipes more smoothly.
The second step: according to the requirements of the formula, add the raw materials and various additives to the mixer according to the specified type and quantity to fully mix. The raw materials after mixing and mixing have a high temperature, and then put the high-temperature raw materials into the cooling machine. After cooling, the cooled raw materials are put into the extruder again, and after extrusion, cutting and shaping of the extruder, the billet of ppr pipe is produced. During this process, the raw material mixture is subjected to strong pressure and friction in the extruder, and the temperature rises again, finally achieving the effect of complete plasticization.
The third step: After the tube blank is cooled, it is gradually shaped, and then formed into a shaped tube by traction, the shaped tube is cut to a certain length, the tube of the same length is inspected, coded, and finally enters the warehouse, and the production of ppr tube is completed.
The fourth step: Every time the pipe production process will inevitably produce waste materials, these waste materials can be crushed again into the extruder and completely mixed with the new materials, used to produce new pipes.
The whole production process of ppr pipe is relatively simple, coupled with its many advantages and cheap price, I believe that ppr pipe will be more and more widely used.
