Abstract

The invention discloses a corrosion-resisting pipe for conveying chemicals. The corrosion-resisting pipe is characterized by consisting of the following raw materials in parts by weight: 84-90 parts of pvc (poly vinyl chloride) resin, 6-10 parts of furfural resin, 3-4 parts of diisononyl phthalate, 10-12 parts of acrylonitrile-butadiene-styrene copolymers, 1-2 parts of sodium silicoaluminate, 2-3 parts of bentonite, 2-3 parts of carbon fibers, 0.7-1 part of stannous octoate, 1-2 parts of 1-hydroxyethyl-2-oleic imidazoline, 2-3 parts of oxidized polyethylene wax, and 8-15 parts of composite fillers. The corrosion-resisting pipe has excellent resistance to acid, alkali and corrosion and is not affected by moisture and soil acidity and alkalinity, so that the corrosion-resisting pipe does not need any anticorrosion treatment during pipeline laying.

Description

Technical field [0001] The invention mainly involves a pipe, especially a corrosion -resistant tube for transporting chemicals. Background technique [0002] The PVC tube (UPVC tube) hard polyethyl chloride tube is a polyvinyl chloride resin and stabilizer, lubricant, etc., and squeezed with heat pressure method. It is the earliest plastic pipes that are developed and applied.The UPVC tube has strong corrosion resistance, easy to bond, low price, and hard texture, but because the UPVC monomer and additive exudate are leaked, it is only applicable to the water supply system that does not exceed 45 ° C.Plastic pipelines are used to transport drinking water, waste water, chemicals, heating fluids and coolant, food, ultra -pure liquid, mud, gas, and compressed air and vacuum systems. Invention content [0003] The purpose of the present invention is to provide a corrosion -resistant tube for transporting chemicals. [0004] The invention is achieved through the following technical s...
