Description

PVC pipe with anti-abrasion structure

Technical Field

The utility model relates to the technical field of construction pipelines, in particular to a PVC pipe with an anti-abrasion structure.

Background

PVC is a material which is mainly composed of polyvinyl chloride and is added with other components to enhance the heat resistance, toughness and ductility of the PVC, the uppermost layer of the surface film is paint, the middle main component is polyvinyl chloride, the lowermost layer is back coating adhesive, the PVC can be divided into soft PVC and hard PVC, wherein the hard PVC accounts for 2/3 in the market, the soft PVC accounts for 1/3, the soft PVC is generally used for the surface layers of floors, ceilings and leather, but the soft PVC contains a plasticizer (which is also the difference between the soft PVC and the hard PVC), has poor physical properties (the soft PVC is not suitable for use if a water supply pipe needs to bear certain water pressure), and the application range of the soft PVC is limited. The hard PVC does not contain a plasticizer, so the hard PVC is easy to form and has good physical properties, thereby having great development and application values.

In the application of the existing PVC pipeline, the PVC pipeline is mostly placed in the open air, so that the PVC pipeline is often abraded due to external force extrusion and rubbing, and the PVC pipeline after long-term abrasion has the phenomenon of bursting and leakage due to thinning of the outer wall, so that certain improvement on the existing PVC pipe is urgently needed. In view of this, we propose a PVC pipe with an anti-wear structure.
