Mildew-proof marking solution and mildew-proof marking process

Abstract

The invention relates to a stainless steel mildew-proof electrolytic marking process, in particular to a mildew-proof marking electrolyte suitable for stainless steel products, especially stainless steel cookers and a preparation method and mildew-proof marking process thereof. After treatment using the mildew-proof marking process, the product defective rate of the stainless steel products due tomildew spots generated by a marking solution and other reasons is greatly reduced. The mildew-proof marking solution comprises, by mass percent, 1-8% of sodium nitrite, 0.1-0.8% of sodium nitrate, 1-8% of potassium pyrophosphate, 1-5% of ammonium chloride, 2-15% of glycerol, 1-15% of a mildew-proof agent and the balance water, wherein the mildew-proof agent comprises, by mass percent, 20-48% of isothiazolinone preservative, 7-20% of a bactericide, 1-8% of sodium hydroxide, 1-8% of sodium carbonate, 2-15% of sodium citrate and the balance water.

Description

technical field

[0001] The invention belongs to the technical field of stainless steel surface treatment, and relates to a stainless steel mildew-proof electrolytic marking process, in particular to a mildew-proof marking electrolyte suitable for stainless steel products, especially stainless steel cookware, a preparation method thereof and a mildew-proof marking process After being treated by the anti-mildew marking process of the present invention, the mildew phenomenon caused by the marking process of stainless steel products is greatly improved. Background technique

[0002] Marking refers to the marking of text and pictures on the product according to the company's own management or publicity needs during production, such as: production date, expiration date, product number, etc. At present, the surface pattern treatment methods of some metal products such as stainless steel, carbon steel, copper and aluminum at home and abroad mainly include: electrochemical marking, l...
