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 crystal whisker corrugated pipe. The crystal whisker corrugated pipe is prepared from the following raw materials in parts by weight: 96-100 parts of high-density polyethylene, 2-3 parts of basic magnesium sulfate crystal whisker, 2-3 parts of calcium carbonate crystal whisker, 2-3 parts of bone charcoal, 1-2 parts of ethyl naphthol, 1-2 parts of ammonium polyphosphate, 0.7-1 part of palm oil, 2-3 parts of precipitated barium sulphate, 1-2 parts of 1,4-cyclohexanedimethanol, 0.6-1 part of butanedioic diisooctyl sodium sulfonate, 0.7-2 parts of glycerin triacetate, 1-2 parts of chitosan and 5-10 parts of compound filler. The corrugated pipe disclosed by the invention has very strong physical performance, friction resistance, impact resistance, high surface hardness, good weather resistance, good pressure resistance and excellent comprehensive performance.

Description

technical field [0001] The invention mainly relates to a pipe material, in particular to a whisker 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 liquef...
