Fin electric heat pipe

Abstract

The invention discloses a fin electric heat pipe. A main body of the metal electric heat pipe is subjected to passivation, and passivation includes the following steps that (1), 1-2 parts of dodecyltrimethylammonium bromide, 2.2 parts of tributyl phosphate, 1.5 parts of hydroxy propyl cellulose, 1.9 parts of ammonium bifluoride and 0.6 part of hydrogen peroxide are put into 35 parts of deionized water in sequence and evenly stirred; (2), 6.3 parts of malonic acid, 1.2 parts of 2-aminoethyl-heptadecenyl-imidazoline, 2.3 parts of pentaerythritol tetraoleate, 1.1 parts of sodium citrate and 2.5 parts of alkylamino alcohol are put into the mixed liquor in sequence and continue to be stirred until the mixed liquor is adequatelyevenly mixed, and finally passivation liquid is obtained; (3), the main body of the metal electric heat pipe is put into the passivation liquid to be subjected to passivation at the treatment temperature of 50 DEG C for 30 seconds, and after being taken out, the main body is cleaned by pure water and then dried. Through passivation of the main body of the metal electric heat pipe, the fin electric heat pipe is good in performance and surface smoothness.

Description

technical field [0001] The invention relates to a fin electric heating tube. Background technique [0002] The existing finned 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 finned electric heating tube, the main body of the metal electric heating tube is passivated to form a uniform passivation protective film on the metal surface, which has excellent rust resistance, corrosion resistance, abrasion resistance, oxidation resistance, Heat resistance and good surface finish. [0004] In order to achieve the above object, the technical solution of the present invention is to design a finned electric heating tube, which includes a metal electric heating tube b...
