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 LCD glass for optimum environment, and the update of the chemical liquid used in the etching apparatus of a liquid crystal glass, and to promote, thereby, the quality of a liquid crystal glass components is obtained. With respect to the liquid of the update method using the etching apparatus of a liquid crystal glass, filling the liquid etchant bath, place the discharge nozzle and the suction nozzle of the chemical liquid and the discharge of a liquid in a state that the immersion nozzle in the liquid, subjected to suction The using of the discharge nozzle, the suction is performed at the same time, constitutes the updating of the drug solution is to be promoted by a uniform stress in the liquid. ;
