Glass etching industry pipe washing agent and washing method thereof

Abstract

The invention discloses a glass etching industry pipe washing agent. The glass etching industry pipe washing agent comprises the following components in parts by weight: 15-30 parts of inorganic acid,2-6 parts of alcohol amine, 1-3 parts of diethylenetriaminepenta(methylene-phosphonic acid), 0.3-0.6 parts of alkyl thioglycolic acid and 3-8 parts of an anionic surfactant. The provided pipe washingagent is capable of, through the synergistic effect of several substances of the inorganic acid, the alcohol amine, the diethylenetriaminepenta(methylene-phosphonic acid), the alkyl thioglycolic acidand the anionic surfactant, effectively cleaning crystal substances on the inner wall of a pipe, wherein the cleaning effect is good and corrosion to the pipe is smaller compared with a traditional acidic washing agent, and effectively prolonging service life of the pipe; and compared with artificial pipe cleaning, greatly saving labor cost and time cost. The invention further provides a method for washing the pipe by the glass etching industry pipe washing agent. The washing method is simple, short in washing time, high in efficiency, and no residual washing agent after washing.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a cleaning agent for pipes in the glass etching industry and a cleaning method thereof. Background technique [0002] Electronic displays are widely used in the electronics industry due to the characteristics of providing vivid images based on excellent resolution, low power consumption, and thinner display screens. With the development of the electronics industry, electronic displays such as liquid crystal displays, touch screens, plasma displays, and organic electroluminescent devices are developing in the direction of thinning and thinning. At present, the thickness of electronic display screens has dropped to 0.28mm or even thinner. Thinning has made related thinning processing enterprises face more severe tests. During the thinning process of the glass used in electronic displays, the reacting liquid will produce a large amount of white powder residue, which is easy...

AI Technical Summary

Problems solved by technology

During the thinning process of the glass used in electronic displays, the reacting liquid will produce a large amount of white powder residue, which is easy to settle and crystallize on the pipe wall and groove wall of the etching equipment. , the white powder slag grows in a lamellar manner, so that the pipeline is blocked, which not only affects the production efficiency of the equipment, but also affects the appearance of glass thinning. In severe cases, the equipment will not work normally

The blockage inside the glass etching pipe is a kind of inorganic crystal, its performance is very stable, it is insoluble in acid and alkali, and it is extremely difficult to remove. At present, the blockage inside the pipe is mainly cleaned manually or the crystal is cleaned with acid cleaning agent , manual cleaning not only takes a long time and is costly, but also leaves some residue after cleaning; using acid cleaners to clean the pipeline for a long time will cause corrosion of the pipeline and shorten the service life of the pipeline
