Description

Technical Field

[0001] The utility model relates to the technical field of etching solution production, in particular to a storage device for etching solution production. Background Technique

[0002] The production of etching solution mainly includes four steps: raw material preparation, mixing and preparation, filtration and purification, and packaging and storage. Specifically, high-quality chemical raw materials such as acids, oxidants, additives, etc. are selected. The purity and quality of these raw materials will directly affect the performance of the etching solution. The prepared raw materials are mixed in a certain proportion and reacted at an appropriate temperature and stirring speed to ensure the reaction effect and product quality. After the reaction is completed, impurities and unreacted substances are removed through filtration and purification steps to improve the purity of the etching solution, and the purified etching solution is stored.

[0003] Generally speaking, acidic etching solution is not likely to precipitate easily during normal storage because the acidic environment helps to maintain the stability of the solution. However, if it is a single-component acidic etching solution, precipitation may still occur when the downtime is too long or the temperature is too low. For alkaline etching solution, the precipitation phenomenon may be more common. During the storage process of alkaline etching solution, due to the influence of chemical reactions and physical changes, and when the storage and collection device is stationary for a long time, precipitation may occur due to too high or too low local concentration, and insoluble precipitates may be produced, which will affect the quality of the etching solution. Therefore, this application proposes a storage device for etching solution production to solve the above problems. Content of the Utility Model
