How to Update the chemical solution used in the etching device for a liquid crystal glass, a chemical solution for updating nozzle and update for the chemical solution

摘要

In order to perform etching of the liquid crystal glass while maintaining an optimum environment, updating of the chemical liquid used for the etching apparatus of the liquid crystal glass is promoted, thereby to obtain a high quality liquid crystal glass part. Regarding the method for updating the chemical solution used for the liquid crystal glass etching apparatus, a nozzle for discharging the chemical liquid and a nozzle for suction are arranged in an etching liquid tank filled with the chemical liquid, and in a state where the nozzle is immersed in the chemical liquid, discharge of the chemical liquid , Suction is performed, discharge and suction using the above-described nozzle are performed at the same time, and updating of the chemical liquid is promoted by applying uniform stress to the chemical liquid.Selection Chart Figure 4
