Abstract

The invention discloses a high-temperature electric heating tube. A metal electric heating pipe main body of the high-temperature electric heating tube is subjected to passivation treatment including the following steps: 1) sequentially dropping 1-2 parts of dodecyl trimethyl ammonium sulfate, 1.6 parts of sodium methyl oleoyl ethanesulfonic acid, 1.1 parts of gamma (methacryloyl oxygen) mercaptopropyltrimethoxysilane, 0.8 part of chromium chloride, and 5.2 parts of malonic acid into 35 parts of deionized water and evenly stirring; 2) sequentially dropping 1.1 parts of urotropine, 1.5 parts of oleic acid triethanolamine soaps, 0.8 part of zinc dialkyl dithiophosphate, 1.6 parts of phosphonic acid di-n-buyl ester salt and 1.8 parts of multi-component copolymerized sodium polyacrylate again and continuously stirring until the components are fully and evenly mixed to prepare a passivation treatment solution; 3) putting the metal electric heating pipe main body into the passivation treatment solution to carry out passivation treatment for 30 seconds at the treatment temperature of 50 DEG C, taking out, cleaning with pure water and drying again. The high temperature electric heating pipe of which the metal electric heating pipe main body is subjected to passivation treatment has good performance and is good in surface finish.

Description

technical field [0001] The invention relates to a high-temperature electric heating tube. Background technique [0002] Existing high-temperature electric heating tubes include the main body of the metal electric heating tube, but the antirust, corrosion resistance, abrasion resistance, oxidation resistance, and heat resistance of the metal electric heating tube body need to be improved, and the surface finish is not ideal. Contents of the invention [0003] The object of the present invention is to provide a high-temperature electric heating tube, the main body of the metal electric heating tube is passivated, and a uniform passivation protective film is formed on the metal surface, which has excellent rust resistance, corrosion resistance, abrasion resistance, oxidation resistance, and corrosion resistance. Thermal performance, and good surface finish. [0004] In order to achieve the above object, the technical solution of the present invention is to design a high-temp...
