Abstract: A method for ablating a coating film, cutting glass, and performing post-treatment by using a laser according to the present invention includes coating one side or both sides of thin mother glass with a coating solution for preventing chemical contact in order to proceed with selective chemical treatment, drying the coating solution to form a coating film on one side or both sides of the thin mother glass, obtaining thin-film glasses in cell units applied to electrical and electronic products from the thin mother glass, healing a laser-cut surface of the cut thin-film glasses in cell units through selective chemical treatment of the cut thin-film glasses in cell units, cleaning the thin-film glasses in cell units, and then ablating all of a coating film formed on a surface of the thin-film glasses in cell units, and cleaning the thin-film glasses in cell units from which all of the coating film has been ablated and then chemically healing the surface of the thin-film glasses in cell units in order to eliminate defects or flaws on the surface of the thin-film glasses in cell units from which all of the coating film has been ablated.

Abstract: A refill system includes a tempering furnace, a refill furnace which stores the molten potassium nitrate obtained by melting powdered potassium nitrate, a supply unit which supplies the molten potassium nitrate to the tempering furnace, a tempering furnace side load measuring unit which measures a load amount of the molten potassium nitrate in the tempering furnace, a refill furnace side load measuring unit which measures a load amount of the molten potassium nitrate in the refill furnace, and a central control unit which checks the load amount of the molten potassium nitrate in the tempering furnace and the refill furnace in real time, and controls the supply unit to stop supplying the molten potassium nitrate to the tempering furnace when the load amount of the molten potassium nitrate in the tempering furnace is greater than or equal to a predetermined load amount.
