The manufacturing method
of plastic pipe
1. Introduction

With the continuous development of the field of chemical production raw materials, the manufacture of plastic pipe has become one of the important industries. Because plastic pipe has the advantages of light weight, corrosion resistance and easy processing, it has been widely used in chemical industry, construction, water conservancy, agriculture and other fields. This article will introduce the manufacturing method of plastic pipe, including raw material preparation, extrusion molding, cooling shaping, traction cutting and other steps.

2. raw material preparation
The first step in
manufacturing plastic pipe is raw material preparation. Commonly used raw materials include polyethylene, polypropylene, polyvinyl chloride and other resins, as well as additives added as needed, such as stabilizers, lubricants, antioxidants, etc. These raw materials need to undergo strict inspection and proportioning to ensure product quality and performance.

3. extrusion molding

after the raw materials are ready, into the extrusion molding stage. Extrusion molding is to melt the raw materials through the extruder, and then form the desired shape of the pipe in the extrusion die. The extruder is generally composed of a screw, a barrel, a mold, etc., in which the rotation of the screw pushes the raw material forward, and heats and melts through the barrel, and finally forms a pipe in the mold.

4. cooling and setting

extruded pipes need to be cooled and set to have a certain strength and hardness. Cooling and shaping generally adopts the method of water cooling, that is, the extruded pipe is put into the cooling water, and the heat on the surface of the pipe is taken away by the water flow, so that it can be rapidly cooled and shaped.

5. traction cutting

After cooling and shaping, the pipe needs to be traction cut to obtain a certain length and diameter of the finished pipe. Traction cutting generally uses equipment such as tractors and cutting saws. By adjusting the traction speed and the position of the cutting saw, pipes of different lengths and diameters can be obtained.

6. quality control

in the manufacturing process of plastic pipe, quality control is a crucial link. It is necessary to ensure that the quality of products meets the relevant standards and regulations through the testing and control of raw materials, production processes and product performance. At the same time, it is also necessary to regularly maintain and maintain the production equipment to ensure the normal operation of the equipment and the stability of the product.

7. environmental protection requirements

With the improvement of people's awareness of environmental protection, the manufacture of plastic pipes also needs to meet environmental protection requirements. In the production process, it is necessary to reduce the discharge of waste gas, waste water, waste residue and other pollutants as much as possible, adopt environmentally friendly materials and processes, and improve the utilization of resources and the sustainability of products. The future development trend of

8.

With the continuous development of science and technology, the manufacturing technology of plastic pipes is also constantly improving. In the future, the manufacturing of plastic pipes will pay more attention to the development of environmental protection, high efficiency and intelligence. At the same time, with the continuous emergence of new materials and new technologies, the performance and application of plastic pipes will be further expanded.

9. conclusion

In short, the manufacturing method of plastic pipe includes the steps of raw material preparation, extrusion molding, cooling and shaping, traction and cutting. In the manufacturing process, we need to pay attention to quality control and environmental protection requirements to improve product performance and sustainability. In the future, with the continuous progress of technology and the expansion of application fields, the manufacturing of plastic pipes will usher in a broader development prospect.
