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
