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 a high-density polyethylene double-wall corrugated tube. The high-density polyethylene double-wall corrugated tube is characterized by comprising the following raw materials in parts by weight: 80 to 86 parts of high-density polyethylene, 2 to 3 parts of polycarbonate, 2 to 3 parts of tetradecanedioic acid, 1 to 2 parts of tartaric acid, 1 to 2 parts of octyl-isothiazolin-ketone, 0.5 to 1 part of tetramethylthiourea, 1 to 2 parts of N-ethyl-p / m-toluene sulfonamide, 4 to 5 parts of fluorite powder, 1 to 2 parts of monopotassium phosphate, 2 to 4 parts of poly-4-methyl-1-amylene, and 7 to 10 parts of composite filler. The corrugated tube disclosed by the invention has high tensile strength, high elongation at break and high notch impact strength, and also has high mechanical properties and anti-friction properties.

Description

technical field [0001] The invention mainly relates to a pipe material, in particular to a high-density polyethylene double-wall corrugated 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 artifici...
