Abstract

The invention relates to a heat-resistant wear-resistant PVC pipe, which is characterized in that the PVC pipe comprises chlorinated polyvinyl chloride resin (CPVC). The invention makes full use of the principle that CPVC has the same chemical polarity with PVC resin and adds the CPVC to the PVC resin, utilizes the characteristics of the CPVC in high temperature resistance and wear resistance on the one hand, and utilizes the characteristics of the PVC resin in easy processing, low price and high pipe pressure-bearing capability so as to produce the heat-resistant wear-resistant PVC pipe low in price.

Description

technical field [0001] The invention relates to a heat-resistant and wear-resistant PVC pipe. Background technique [0002] PVC pipe has the characteristics of strong corrosion resistance, high strength, and good rigidity. Therefore, it is widely used in technical fields such as water supply, building drainage, sewage discharge, and chemical industry. It is a plastic pipe with a scope of application second only to polyethylene. However, because PVC pipes have general wear resistance and cannot be used at higher temperatures, they cannot be used to transport liquids containing waste slag produced by industrial and mining enterprises such as power plants, calcium carbide plants, and lead mines. It affects the application of PVC pipes. Contents of the invention [0003] The object of the present invention is to overcome the defects of the above-mentioned prior art, and provide a PVC pipe material that not only maintains the high strength and corrosion resistance characterist...
