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 dirt-resistant and dust-free PVC (Poly Vinyl Chloride) pipe which is characterized by being composed of the following raw materials in parts by weight: 70-75 parts of PVC resin, 1-2 parts of methylcellulose, 0.5-1 part of zinc phosphate, 2-3 parts of polyvinyl ether, 1-3 parts of ethylhexyl epoxystearate, 2-3 parts of inositol hexaphosphate, 0.8-1 part of dibutyltin dilaurate, 1-3 parts of polytetrafluoroethylene wax, 0.6-1 part of N,N-diethyl aniline, 3-5 parts of high-wear-resistant carbon black, 0.8-1 part of hydrogenated castor oil, 0.6-1 part of 1-hydroxy-cyclohexyl phenyl ketone and 7-10 parts of composite filler. The dirt-resistant and dust-free PVC pipe disclosed by the invention is capable of self-cleaning and removing dirt on the outer surface, good in sterilizing effect, not easy for dust adhesion, wide in application range, strong in weather resistance, excellent in anticorrosion performance and long in service life.

Description

technical field [0001] The invention mainly relates to a pipe material, in particular to a dirt-resistant, dust-free PVC pipe material. 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, natur...
