Description

Technical Field

[0001] The utility model relates to the technical field of PVC pipes, in particular to a high-strength and tough PVC pipe. Background Art

[0002] PVC pipe, full name polyvinyl chloride pipe, is a plastic pipe made of polyvinyl chloride resin as the main raw material, with the addition of stabilizers, lubricants and other auxiliary agents, and processed by hot pressing or extrusion. PVC pipes are mainly divided into two categories: hard PVC pipes and soft PVC pipes. Among them, hard PVC pipes occupy a larger share of the market. Hard PVC pipes are usually used in situations that need to withstand a certain pressure or require high mechanical strength, such as tap water piping, water-saving irrigation piping, etc. Soft PVC pipes are usually used for floors, ceilings and leather surfaces due to their softness and easy processing.

[0003] To this end, Chinese patent publication number CN202349568U discloses a PVC pipe with a cross-section that has one flat surface and at least one of the other three corrugated surfaces. This utility model provides a PVC pipe that takes up less space and is effectively applicable to corrugated building exteriors.

[0004] Today's PVC pipes can basically meet people's needs, but there are still some problems. The specific problems are as follows:

[0005] 1. The problem that PVC pipes are difficult to install conveniently. When installing and using PVC pipes, it is often necessary to fix the PVC pipes on various planes. Due to the different lengths and sizes of PVC pipes, it is difficult to install the PVC pipes quickly according to needs.

[0006] 2. PVC pipes are difficult to have high strength and toughness. In actual applications, PVC pipes often need to withstand certain internal and external pressures. At the same time, they may also be eroded by various environmental factors. Under long-term pressure and erosion, PVC pipes are prone to deformation or even rupture, making them unable to continue to be used, increasing maintenance costs. Utility Model Content

[0007] The purpose of the utility model is to provide a high-strength and toughness PVC pipe material, so as to solve the defects of the existing PVC pipe material that it is difficult to install conveniently and has high strength and toughness.
