A kind of soaking liquid and its preparation method and use method

Abstract

The invention discloses a soak solution. The soak solution comprises the following components: in percent by weight, 7-10% of amino acid, 8-10% of citric acid, 3-5% of hydroxyethylidene-1,1-diphosphonic acid, 2-3% of a nonionic surfactant, 0.5-1% of a zwitterionic surfactant, 0.5-1% of an anionic surfactant, 2-3% of dimethyl sulfoxide and the balance water. The invention also discloses a preparation method and application method of the soak solution. The soak solution has the characteristics of a good cleaning effect, a high yield, low cost, environmental protection, no inorganic matter and noheavy metal.

Description

technical field [0001] The invention relates to a soaking liquid, in particular to a soaking liquid, a preparation method and a use method thereof. Background technique [0002] my country is rich in rare earth resources, and the reserves of industrial cerium resources are as high as 18 million tons. Cerium oxide polishing materials are used in many aspects due to their advantages such as strong cutting ability, short polishing time, high polishing precision, and clean operating environment, such as The polishing of lenses, optical fibers, optical components, silicon wafers, ITO glass, mobile phone glass, aviation glass, integrated circuit substrates, etc. has become one of the important materials for chemical mechanical polishing. [0003] Most of the optical glass materials in the prior art are made of silica, cut into various shapes, and then subjected to a surface polishing process. The cerium oxide (rare earth) used in the polishing process has a particularly strong visc...

AI Technical Summary

Problems solved by technology

[0003] Most of the optical glass materials in the prior art are made of silica, cut into various shapes, and then subjected to a surface polishing process. The cerium oxide (rare earth) used in the polishing process has a particularly strong viscosity after being mixed with water. The grinding powder cannot be cleaned, how to clean it is a very tricky problem

The method for removing powdery cleaning agent in the prior art has the following several: 1, use potassium ferricyanide to soak in water, and the cleaning effect is unsatisfactory; It is softened and loosened, but it needs to be soaked for at least 5 minutes, and the treatment efficiency is slow. In addition, the biggest disadvantage is that the sewage cannot be effectively treated

3. Using a strong alkaline optical cleaning agent for treatment requires repeated cleaning, which increases the rate of backwashing, which increases the chance of scratching the glass, resulting in low yield and high production costs.
