METHOD OF REGENERATING MOLTEN SALT FOR CHEMICALLY TOUGHENING GLASS, AND PRODUCTION METHOD OF TOUGHENED GLASS |
摘要 |
<p>The purpose of the present invention is to provide a method of regenerating molten salt which, when there is a reduction in the CS value of molten salt containing potassium nitrate used for chemically toughening glass, can restore said salt to a state in which a high CS value can be imparted. The present invention relates to a method of regenerating molten salt for use in glass strengthening which is used for forming a compressive stress layer on the glass surface by means of ion exchange, and involves a step in which the aforementioned molten salt contains potassium nitrate and a potassium orthophosphate is added to the molten salt after ion exchange treatment.</p> |
