Abstract

The invention discloses an efficient TFT-LCD glass substrate cleaning agent. The efficient TFT-LCD glass substrate cleaning agent comprises the following raw materials in parts by weight: 13 to 18 parts of sodium bicarbonate, 9 to 14 parts of sodium tripolyphosphate, 7 to 11 parts of monoethanolamine, 6 to 10 parts of isopropanol, 12 to 16 parts of fatty alcohol-polyoxyethylene ether, 8 to 15 parts of sodium dodecyl benzene sulfonate, 13 to 15 parts of ethylene glycol butyl ether, 3 to 5 parts of a bacteriostatic agent, 6 to 9 parts of a nonionic surfactant and 66 to 80 parts of deionized water. The glass substrate cleaning agent provided by the invention does not have toxicity, corrosivity or volatile organic compounds, is non-flammable and non-explosive, has easily available raw materials, is simple to prepare and convenient to use, avoids environmental pollution, has high granule cleaning capability, and can accord with the cleaning quality requirement of the TFT-LCD glass substrate, realize two-stage filtration through 1-micron and 100-nm filtration, effectively remove the granular impurities from the cleaning agent, and avoid secondary pollution in the cleaning process of the TFT-LCD glass substrate.

Description

technical field [0001] The invention relates to the technical field of TFT-LCD, in particular to a high-efficiency TFT-LCD glass substrate cleaning agent. Background technique [0002] The liquid crystal glass substrates currently used commercially have a main thickness of 0.7 mm to 0.4 mm. Basically, a TFT-LCD panel needs to use two glass substrates, which are respectively used as the bottom glass substrate and the bottom plate of the color filter. During the processing of liquid crystal glass substrates, only clean and cleaned glass substrates can be introduced into the packaging process for finished product packaging and storage. The cleaning effect of the glass substrate is mainly measured by measuring the number of particles attached to the surface of the cleaned substrate. The lower the number of particles, the better the cleaning effect and the better the quality of the finished product. By observing and counting the particle distribution of the cleaned glass substr...
