Problems solved by technology

Because liquid crystals are mostly highly polar macromolecular compounds with strong intermolecular forces, they are not easy to disperse in water. Therefore, in the past, organic cleaning agents were generally used to clean residual liquid crystals; organic cleaning agents degrade in the environment Slow, causing great pressure on the environment. Therefore, it is gradually developing towards water-based cleaning agents, but the cleaning power of water-based cleaning agents is weak, and it is not easy to clean the residual liquid crystal.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to an efficient and environment-friendly liquid crystal display cleaning agent. Background technique [0002] In the manufacturing process of the liquid crystal display, two glass substrates are usually bonded first, leaving a part of the opening, and after filling the liquid crystal, the opening is sealed with a sealant, and then the liquid crystal remaining outside the opening is cleaned. Because liquid crystals are mostly highly polar macromolecular compounds with strong intermolecular forces, they are not easy to disperse in water. Therefore, in the past, organic cleaning agents were generally used to clean residual liquid crystals; organic cleaning agents degrade in the environment Slow, causing great pressure on the environment. Therefore, water-based cleaning agents are gradually developing, but the cleaning power of water-based cleaning agents is weak, and it is not ...
