METHOD FOR RENEWING CHEMICAL SOLUTION USED FOR DEVICE FOR ETCHING LIQUID CRYSTAL GLASS NOZZLE FOR CHEMICAL SOLUTION RENEWAL AND CHEMICAL SOLUTION FOR RENEWAL

摘要

In order to perform the etching of the liquid crystal glass in an optimum environment, the chemical liquid used in the etching apparatus of the liquid crystal glass is promoted to be updated, thereby obtaining a high-quality liquid crystal glass component. Regarding the method of renewing the liquid chemical used for the liquid crystal glass etching apparatus, the chemical liquid dispensing nozzle and the suction nozzle are arranged in the etching liquid tank filled with the chemical liquid, and the chemical liquid is discharged and sucked in the chemical liquid immersed in the chemical liquid , Ejection and suction using the above-described nozzles are performed at the same time, and uniform stress is applied to the chemical liquid, thereby promoting the update of the chemical liquid.;
