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 nylon corrugated pipe which is characterized by being composed of the following raw materials in parts by weight: 93-100 parts of polypropylene T30S, 30-36 parts of nylon 610, 1-2 parts of methacrylic acid, 2-3 parts of dibutyl phthalate, 1-2 parts of aluminum tripolyphosphate, 0.8-1 part of methyltin mercaptide, 2-3 parts of tricalcium silicate, 1-2 parts of 2-phenyl-2-imidazoline, 1-3 parts of diisopropylethanolamine, 0.6-1 part of 2-hydroxy-4-n-octyloxybenzophenone, 1-2 parts of pine tar and 10-12 parts of composite filler. The corrugated pipe disclosed by the invention has favorable high temperature resistance, is particularly suitable for being used as a corrugated pipe material dried under a high temperature condition, and is wear-resistant, strong in chemical corrosion resistance, high in surface glossiness, long in service life, strong in impact resistance and high in hardness.

Description

technical field [0001] The invention mainly relates to a pipe material, in particular to a nylon 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 artificial gas, natural gas and liquefie...
