Problems solved by technology

[0004] However, PVC-U has insufficient toughness, that is, high brittleness, poor impact resistance and crack resistance, and is prone to brittle failure when subjected to strong external impact.
In actual application, especially in areas with complex geological conditions, falling stones and rocks at the bottom of the ditch may cause damage to PVC-U pipes

Description

technical field [0001] The invention relates to a PVC pipe material, more specifically to an impact-resistant modified polyvinyl chloride pipe material for water supply, and belongs to the technical field of pipe materials. Background technique [0002] The application of PVC-U pipes began in the 1930s and has a history of more than 70 years. It is a product with relatively mature production technology, experimental testing, standardization, design and construction specifications. Because of its good cost performance and excellent physical and mechanical properties, it has been widely used in engineering. It is still the plastic pipe with the largest consumption, accounting for about 62% of the entire plastic pipe market. [0003] PVC-U products are widely used due to its good mechanical properties, as well as its economy and environmental protection. Among various thermoplastic piping materials, PVC has the strongest strength and the cheapest price. The short-term streng...
