Abstract

The invention discloses a straight electrical heating tube. A metal electrical heating tube main body of the straight electrical heating tube is passivated through the following steps of 1) feeding 1-2 parts of coco trimethyl ammonium chloride, 2.2 parts of isomeric alcohol ethoxylate, 1.3 parts of sodium polyacrylate, 1.8 parts of acrylic amide and 0.9 part of potassium chlorate in sequence into 35 parts of deionized water, and uniformly mixing; 2) feeding 0.7 part of cobalt nitrate, 1.1 parts of castor oil, 2.6 parts of octaphenyl polyoxyethyiene, 1.5 parts of polymeric alkylol amine and 1.2 parts of sodium tripolyphosphate in sequence, and continuously mixing till sufficiently and uniformly mixing so as to prepare a passivated treating fluid; and 3) putting the metal electrical heating tube main body in the passivated treating fluid for passivating, wherein the passivating treatment temperature is 50 DEG C, and the passivating treatment time is 30 s, and after taking out the metal electrical heating tube main body, cleaning with purified water and then drying. After the metal electrical heating tube main body is passivated, the straight electrical heating tube is high in performance, and is high in surface smoothness.

Description

Technical field [0001] The invention relates to a straight electric heating tube. Background technique [0002] The existing straight electric heating tube includes a metal electric heating tube main body, but the metal electric heating tube main body needs to be improved in anti-rust, corrosion resistance, abrasion resistance, oxidation resistance, and heat resistance performance, and the surface finish is not ideal. Summary of the invention [0003] The purpose of the present invention is to provide a straight electric heating tube whose main body is passivated to form a uniform passivation protective film on the metal surface, which has excellent rust resistance, corrosion resistance, abrasion resistance, and oxidation resistance. Heat resistance and good surface finish. [0004] In order to achieve the above objective, the technical solution of the present invention is to design a straight electric heating tube, which includes a metal electric heating tube main body, the metal ...
