Surface cleaning agent for sensor zinc-plating shell

Abstract

The invention discloses a surface cleaning agent for a sensor zinc-plating shell. The surface cleaning agent mainly comprises XP-80, TX-10, phenanthroline, phytic acid, sodium salicylate, a citric acid corrosion inhibitor, hydrochloric acid, a hydrochloric acid fog inhibitor and water, wherein the hydrochloric acid fog inhibitor comprises the following components in percentage by weight: 8-18% of a corrosion inhibitor, 4-8% of a fog inhibitor, 8-15% of a surfactant and the balance of water. By adopting the surface cleaning agent for the sensor zinc-plating shell disclosed by the invention, over-corrosion and acid fog formation can be inhibited, the consumption of materials and hydrochloric acid can be saved, the service life of hydrochloric acid can be prolonged, and environmental protection can be achieved. In addition, the invention also provides a surface cleaning agent for a sensor zinc-plating shell. By adopting the surface cleaning agent for the sensor zinc-plating shell, the cleaning time can be shortened, and the corrosion can be reduced. Meanwhile, by adopting the surface cleaning agent for the sensor zinc-plating shell, an anti-rust layer can also be formed on the cleaned metal surface so as to prevent the cleaned metal surface from rusting again.

Description

technical field [0001] The invention relates to a cleaning agent, which belongs to the technical field of iron and steel products and material surface treatment industry, in particular to a surface cleaning agent for a sensor galvanized shell, which is mainly used in the hydrochloric acid cleaning process before or after galvanizing. Background technique [0002] The application number published on December 5, 2007 is Chinese Invention Patent No. 200710025061.3. The name of its invention is "a galvanized metal cleaning agent", which includes organic complexing agent, o-phenanthroline, water, and organic complexing agent. The weight ratio of agent, o-phenanthroline, water is 3-10: 0.005-0.04: 100. [0003] The above patent application cleverly utilizes the scale-dissolving ability of organic complexing agents, which can effectively remove oil stains and calcium and magnesium ions, and o-phenanthroline can effectively remove free ferrous ions. However, it is difficult to remo...

AI Technical Summary

Problems solved by technology

As a result, the metal product substrate will be corroded, a large amount of material will be lost, and excessive hydrochloric acid will be consumed, which will not only shorten the service life of hydrochloric acid, reduce the processing capacity, but also affect the air quality of the workshop due to the escape of acid mist, seriously endangering the health of workers

[0009] 2. The long cleaning time required increases the corrosion time of the "acid mist" formed by hydrochloric acid on the metal product substrate, so the corrosion rate increases

[0010] 3. After metal products are cleaned, rust spots will still appear on the surface after a short time
