Abstract

The present invention is one kind of demisting agent for deplated surface of non-metal material. The demisting agent includes hydrofluoric acid in 0.1 mol / l, nitric acid in 0.02 mol / l, sodium fluoride in 0.025 mol / l, acid surfactant in 0.01 vol%, and high purity water. The demisting agent is applied in washing the deplated surface of non-metal material before washing with high purity water, and can obtain high surface smoothness and high cleanliness.

Description

technical field [0001] The invention relates to a surface defogging agent after deplating coating, in particular to a surface defogging agent after deplating non-metallic surface coating. technical background [0002] In recent years, a large number of decorative panels such as mobile phones and household appliances use non-metallic substrates to increase the metallic luster of the panels through vacuum coating. There will be a process of vacuum coating and etching and deplating in the production process of decorative panels. After the substrate is stripped, a layer of white mist will appear on the surface, which greatly affects the appearance of the decorative panel. Contents of the invention [0003] In view of the problems existing in the prior art, the present invention provides a kind of defogging agent that can completely remove the white mist-like substance produced on the surface of the non-metallic surface coating after deplating, and its technical solution is; S...
