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.

Embodiment 1

[0016] A pipe for irrigation, water delivery and drainage of farmland water conservancy, which is composed of the following raw materials in parts by weight (kg):

[0017] High-density polyethylene 97, dodecyltrimethylammonium chloride 0.7, zinc oxide 2, ethylene glycol dimethacrylate 2, pyromellitic dianhydride 0.6, glycerin 2, maleic anhydride grafted polypropylene 2. Zirconia 2, sodium antimonate 2, sillimanite 3, butyl tin mercaptide 0.4, antioxidant 1010 0.6, composite filler 14;

[0018] Described composite filler is made up of the raw material of following weight part:

[0019] Red clay 30, medical stone powder 20, rosin 4, calcium acetylacetonate 0.8, aluminum nitride 2, hexagonal boron nitride 2-3, propolis 2;

[0020] Calcinate the above-mentioned laterite at 900°C for 2 hours, mix it with aluminum nitride and hexagonal boron nitride after discharging, and grind to obtain a powder; heat and melt the above-mentioned rosin, mix it with medical stone powder, calcium ac...

Abstract

The invention discloses a pipe for irrigation, water delivery and drainage in farmland water conservancy. The pipe is characterized by being composed of the following raw materials in parts by weight: 90-97 parts of high-density polyethylene, 0.7-1 part of dodecyl trimethyl ammonium chloride, 1-2 parts of zinc oxide, 2-3 parts of dimethacrylic acid glycol ester, 0.6-1 part of pyromellitic dianhydride, 2-3 parts of glycerin, 2-3 parts of maleic anhydride grafted polypropylene, 1-2 parts of zirconia, 1-2 parts of sodium antimonite, 2-3 parts of sillimanite, 0.1-0.4 part of butylmercaptooxo-stannane, 0.6-1 part of antioxidant 1010 and 8-14 parts of composite filler. The corrugated pipe disclosed by the invention is good in circulation, smooth in inner wall, small in frictional resistance and favorable in deposition and blockage preventing capability.

Description

technical field [0001] The invention mainly relates to a pipe material, in particular to a pipe for irrigation, water delivery and drainage of farmland water conservancy. 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 tran...
