preparation example Construction

[0064] One embodiment of the present invention also provides a preparation method of the above-mentioned acid cleaning agent, including the following step S10.

[0065] Step S10 , mix water, organic acid, inorganic acid, reducing agent, pH buffering agent, chelating agent and surfactant according to the composition ratio of the above-mentioned acidic cleaning agent to obtain an acidic cleaning agent.

[0066] Specifically, in step S10, organic acid, inorganic acid, reducing agent, pH buffering agent, chelating agent and surfactant are sequentially added to water, stirred and mixed, and diluted 10-15 times for use.

[0067] An embodiment of the present invention also provides the application of the above-mentioned acid cleaning agent in cleaning glass.

[0068] In some of the embodiments, the above glass is polished glass with rare earth polishing powder remaining on its surface.

[0069] Rare earth polishing powder is a rare earth based polishing powder, including but not lim...

Embodiment 1

[0074] Specific steps are as follows:

[0075] 1) Provide 500 pieces of polished glass, the polishing powder used is: cerium oxide.

Abstract

The invention relates to an acidic cleaning agent as well as a preparation method and application thereof. The acidic cleaning agent comprises the following components in percentage by mass: 5%-20% of organic acid, 3%-10% of inorganic acid, 5%-30% of a reducing agent, 1%-8% of a pH buffering agent, 1%-8% of a surfactant, 1%-5% of a chelating agent and the balance of water. The organic acid, the inorganic acid and the pH buffering agent in a specific ratio are matched to provide a specific acidic cleaning environment, and in the acidic environment, the polishing powder shows strong oxidizing property; and meanwhile, the reducing agent with a specific ratio is added, so that the polishing powder and the reducing agent are subjected to a chemical reaction quickly in a specific acid environment, the wetting and dispersing effects of the chelating agent and the surfactant with a specific ratio are matched, and all the components with specific ratios are coordinated and matched, so that the polishing powder on the surface of glass can be treated very quickly, and the glass is not damaged.

Description

technical field [0001] The invention relates to the field of glass cleaning, in particular to an acid cleaning agent and its preparation method and application. Background technique [0002] In the production process of glass components, in order to reduce the roughness of the glass surface, the surface of the glass needs to be polished. During the polishing process, the surface of the glass is usually polished with polishing powder, and a part of the polishing powder remains on the glass surface after polishing. On the one hand, the polishing powder particles remaining on the surface of the glass element will corrode the surface of the glass element. For example, the remaining polishing powder particles on the optical glass element after precision polishing are one of the key factors affecting the ability of the element to resist laser radiation damage; On the other hand, after the glass component is assembled on the electronic product, the polishing powder remaining on th...
