What are the advantages of the OPVC pipe production line? – Suzhou Polytime Machinery Co., Ltd.

Many high molecular polymers can significantly improve their properties by arranging their molecules regularly through orientation processing (or orientation). The competitive advantage of many plastic products in the market depends on the excellent performance brought by orientation processing, such as fiber, biaxial tensile film, container, etc. On the one hand, oriented processing technology can improve pipe performance, on the other hand, it can reduce material consumption. It is cutting-edge technology in line with the general direction of sustainable development. PVC pipe is a pipe made by a special orientation process. It is the latest evolution form of PVC pipe.

What is OPVC pipe?
Biaxially oriented polyvinyl chloride (OPVC) pipe is made with special orientation processing technology. This processing technology is to carry out axial and radial stretching on the UPVC pipe produced by the extrusion method, so that the PVC long-chain molecules in the pipe are arranged regularly in the biaxial direction, to obtain a new PVC pipe with high strength, high toughness, high impact resistance, and fatigue resistance, and its performance is far better than that of ordinary UPVC pipe. The research and development of OPVC pipe and OPVC pipe production line can greatly save raw material resources, reduce costs, improve product performance, and have obvious economic and social benefits.

What are the precautions of the OPVC pipe production line?
The preferred OPVC pipe processing technology is "online" orientation in the extrusion process, but the following problems often need to be considered in the design of the pipe production line.

1. Without knowing the heating experience and drawing rate, how will the drawing ratio affect the mechanical properties of PVC in drawing processing or the properties of the final product. Without knowing the temperature tolerance to be achieved, it can only be qualitatively estimated based on the results obtained from the "off-line" processing process.

2. It is necessary to control the material at the required temperature at a distance from the extruder for heat treatment and expansion at a certain point of the production line. Whether the expansion is carried out by mechanical method or hydraulic method, it needs to be equipped with a device in the pipe. Such a device is easy to be damaged, resulting in production line accidents, and there is a great reaction force between the device in the pipe and the pipe itself, which needs to be controlled by the traction equipment and the anchoring system.

3. Set a stable expansion considering the balance of axial force and the obtained stress and axial variation.

What is the development prospect of the OPVC pipe production line?

The change and development of the international situation provide an unprecedented historical opportunity for the development of the PVC pipeline system in China. The soaring oil price has seriously affected the polyolefin pipeline system competing with PVC pipeline system in many application fields, and the PVC with coal as raw material has enhanced its competitiveness by maintaining a low price. Because the PVC pipe system has the advantages of high modulus, high strength, and low price, it has always been the largest plastic pipe system in the world and has been widely used in many fields of modern society.

In addition, the criticism of environmental protection organizations of various countries on chlorine makes PVC pipes face a severe situation. But what people have neglected for a long time is that PVC pipe can better prevent the penetration of some toxic and harmful substances than PE pipe. PVC pipes will dominate the world pipe market in the future. The fundamental reason lies in technological innovation and technological progress. The application of innovative technologies of PVC resin and PVC pipeline, especially the innovation of PVC pipeline processing technology and process, has significantly improved the economy of PVC pipeline and opened up new application fields. Therefore, we must save materials while improving the performance of pipes, to improve the competitiveness of PVC pipes, develop new PVC pipes, such as OPVC pipes, and further improve and develop the pipe production line.

Due to its extraordinary versatility, outstanding durability, and economy, PVC will still be the preferred material for pipes in the future. As a new type of pipe, OPVC has the advantages of good performance, low cost, lightweight, easy handling, and laying. Its super performance makes it can be applied to higher pressure and worse environment. Reducing product cost and improving its performance is a subject that people have been pursuing, but it is not easy to realize. PVC pipe not only provides an example for this subject but also lays a foundation for the future development of a new product.
