Problems solved by technology

The disadvantage is that the equipment is not as good as steel pipes. During construction, special attention should be paid to the safe distance of thermal heating, and it cannot be exposed to sunlight in the air, and it is sensitive to chemicals to prevent damage caused by leakage of sewage pipes.

Abstract

The invention discloses an antibacterial type high-density polyethylene tube. The antibacterial type high-density polyethylene tube is prepared from the following raw materials in parts by weight: 80-84 parts of high-density polyethylene, 0.8-1 part of polycarbodiimide, 1-2 parts of epoxy tetra hydro dioctyl phthalate, 1-2 parts of captan, 2-3 parts of oxidized polyethlene wax, 2-3 parts of cellulose acetate fiber, 0.7-2 parts of potassium perfluorobutanesulfonate, 0.5-1 part of N-hydroxymethyl acrylamide, 1-2 parts of ethyl naphthol, 0.2-0.4 parts of waste scrap iron, 4-6 parts of wollastonite powder and 10-13 parts of compound filler. The tube disclosed by the invention has good antibacterial effect, good impact resistance and heat resistance; the physical performances of the tube are greatly improved by the added compound filler; moreover, the antibacterial type high-density polyethylene tube has good ring stiffness and extensive applicability.

Description

technical field [0001] The invention mainly relates to a pipe material, in particular to an antibacterial high-density polyethylene pipe. Background technique [0002] PVC pipe (UPVC pipe) Rigid polyvinyl chloride pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc., and is extruded by hot pressing. It is the earliest plastic pipe that has been developed and applied. UPVC pipe has strong corrosion resistance, easy bonding, low price, and hard texture. However, due to the leakage of UPVC monomer and additives, it is only suitable for water supply systems with a delivery temperature not exceeding 45°C. Plastic piping is used in applications for conveying potable water, waste water, chemicals, heating and cooling fluids, food, ultrapure liquids, slurries, gases, compressed air and vacuum systems. [0003] PE pipes include medium-density polyethylene pipes and high-density polyethylene pipes. The former is suitable for transporting gaseous artificial gas, nat...
