Abstract

The invention relates to an optical element cleaning agent and a cleaning method thereof. The cleaning agent comprises the following components: sodium hydroxide, sodium tripolyphosphate, sodium silicate, sodium dodecyl benzene sulfonate and emulsifiable penetrant. The cleaning method comprises: preparing a cleaning agent by mixing sodium hydroxide, sodium tripolyphosphate and emulsifiable penetrant according to a weight percentage ratio and dissolving the cleaning agent in water in a container to form cleaning agent aqueous solution I; preparing a cleaning agent by mixing the raw materials including sodium silicate, sodium dodecyl benzene sulfonate and emulsifiable penetrant, and dissolving the cleaning agent in water in a container to form a cleaning agent aqueous solution II; using the cleaning agent aqueous solution I and the cleaning agent aqueous solution II with assistance from ultrasonic waves and a pure water conductivity of greater than 8Mohm, wherein the concentration of the cleaning agent aqueous solution I and the concentration of the cleaning agent aqueous solution II are both 0.1 to 0.8 percent and the temperature of the aqueous solutions is 30 to 70 DEG C; and performing the steps of rinsing, dewatering, steaming and the like to accomplish cleaning. The cleaning method is convenient to use, low in cost and good in cleaning effect.

Description

technical field [0001] The invention relates to a cleaning agent and a cleaning method thereof, in particular to an optical element cleaning agent and a cleaning method thereof. Background technique [0002] In optical processing, component contamination mainly comes from grinding (powder) liquid residue, finger prints and a small amount of fatty oil. such as CeO 2 (Cerium dioxide) as the main component of the grinding powder will not cause corrosion to the lens, but when grinding, the grinding liquid is made of water and grinding powder, so the initial pH value of the newly prepared grinding liquid is It is determined by the acidity and alkalinity of water and grinding powder, and is generally alkaline (pH>7). As mentioned earlier, when glass meets water, it will undergo a hydrolysis reaction, as shown in Equation I: And the generated H 2 SiO 3 (Silicic acid) is in a gel state, attached to the surface of the glass for protection, preventing the reaction from procee...
