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-hardness corrugated pipe. The high-hardness corrugated pipe is characterized by consisting of the following raw materials in parts by weight: 96-100 parts of high-density polyethylene, 2-3 parts of potassium feldspar powder, 1-2 parts of tung oil, 1-2 parts of sodium hydrogen phosphate, 2-3 parts of montmorillonite powder, 0.3-0.6 part of dimethylaminopropylamine, 0.3-1 part of antiscorching agent CTP, 2-3 parts of polytetrafluoroethylene, 1-2 parts of polylactic acid, 2-3 parts of aluminum nitride, 0.1-1 part of cuprous chloride, 0.1-0.2 part of fenbutatin oxide and 6-10 parts of composite fillers. The corrugated pipe disclosed by the invention has high mechanical property and friction resistance, high hardness, good impact resistance and ring stiffness, excellent pressure resistance and good stability.

Description

technical field [0001] The invention mainly relates to a pipe material, in particular to a high-hardness 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 ...
