Abstract

The invention discloses a formula of a rapid anti-corrosion phosphating solution. The formula comprises phosphoric acid, zinc oxide, zinc nitrate, tartaric acid, potassium dichromate, ammonium molybdate, barium nitrate and a skin care hand sanitizer. According to the formula, the phosphating solution is simple in construction process, can quickly realize in-situ and local anti-corrosion implementation, and is conductive to meeting the anti-corrosion requirements of large components.

Description

technical field [0001] The invention relates to the technical field of iron and steel metal anticorrosion, in particular to a formulation of a rapid anticorrosion phosphating solution. Background technique [0002] Phosphating is one of the process technologies for steel metal anticorrosion. The commonly used phosphating solution formulations are used at high temperature (95°C-98°C); medium temperature (60°C-80°C) and low temperature (30-50°C). fixed in the tank. The usage scenario is also limited to the overall processing of a single part after decomposition. [0003] According to the requirements of in-situ repair technology, the above-mentioned phosphating solution that needs to be heated cannot be used. For this reason, it is necessary to solve the implementation of the normal temperature rapid phosphating process, and it is necessary to study the formula of the normal temperature phosphating solution. Contents of the invention [0004] The object of the present in...
