Glass cleaning agent composite for electronic industry

Abstract

The electronic industrial glass cleaning agent composition belongs to the field of electronic industrial cleaning technology. The cleaning agent consists of sodium metasilicate, sodium hydroxide, sodium carbonate, sodium bicarbonate, Pluronic polyol, CMC, fluoric surfactant, complexing agent, defoaming agent and deionized water. It is used to clean substrate glass and coated conducting glass. During the cleaning, the cleaning agent in 1-5 % is compounded with deionized water in 95-99 % to compound the cleaning liquid for showering or ultrasonic cleaning to eliminate pollutant on glass fastcompletely. It is used to replace strong acid and strong alkali cleaning agent and has no damage to glass surface and no corrosion to ITO film. The cleaning agent has no bad smell, no toxicity and no corrosion, and is safe, reliable, environment friendly and low in 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...

Problems solved by technology

Therefore people expect to develop high-performance non-halogen cleaning agents that can replace strong acids, strong alkalis, and ODS substances, but there is no such cleaning agent with excellent cleaning performance.
