Embodiment 2
[0040] Embodiment 2. as described in embodiment 1, difference is that sodium metasilicate is sodium metasilicate nonahydrate (produces in Tianjin, white granule), and complexing agent is sodium citrate.
[0041] detergent
[0042] Component
[0043] The appearance of the above cleaning agent is a colorless uniform transparent liquid with a specific gravity of 1.02, a viscosity of 24 centipoise and a pH value of 12.5. According to the cleaning agent usage method mentioned above, online spray cleaning can effectively remove grease, dust and other pollutants on the glass surface.
Embodiment 4
[0045] As described in Example 3, the difference is that the sodium metasilicate is sodium metasilicate nonahydrate (produced in Tianjin, white granules), and the complexing agent is disodium edetate.

Abstract
The invention discloses a glass cleaner composition for the electronic industry, which belongs to the technical field of cleaning for the electronic industry. The cleaning agent components are: sodium metasilicate, sodium hydroxide, sodium carbonate, sodium bicarbonate, Pluronic polyol, carboxymethyl cellulose, fluorosurfactant, complexing agent, defoamer, deionized water. The cleaning agent composition of the invention is used for cleaning substrate glass and coated conductive glass. Cleaning method: Mix 1-5% of the cleaning agent with 99-95% deionized water to make a cleaning solution, spray or ultrasonic cleaning, which can quickly and thoroughly clean the pollutants on the glass, replacing traditional strong acid and strong alkali cleaning agents and ODS material cleaning agent, no damage to the glass surface, no corrosion to the ITO film. The cleaning agent of the invention has no peculiar smell, is non-toxic and non-corrosive, is safe and reliable, is non-flammable and non-explosive, does not pollute the environment, and has low manufacturing cost, convenient transportation and storage, and low cleaning cost.
Description
(1) Technical field [0001] The invention relates to a glass cleaning agent composition for the electronic industry, in particular to a cleaning agent composition and a cleaning method for substrate glass and coated conductive glass, and belongs to the technical field of cleaning for the electronic industry. (2) Background technology [0002] Liquid crystal display (LCD) is the crystallization of the development of multidisciplinary technology. It has expanded from the application of watches and calculators to various fields such as instrumentation, communication equipment, computer TV, etc. Transparent conductive glass is an important raw material in the production of LCD. First of all, the substrate glass will be contaminated with glass powder, oil, dust, fibers, fingerprints and other pollutants during the cutting and transportation process. These pollutants seriously affect the quality of the coating. The Indium Tin (ITO) film is pre-cleaned precisely. Secondly, after th...
