Method for improving electronic glass reinforced size expansion phenomenon and preparation method of reinforced glass

The invention relates to the technical field of electronic glass processing, in particular to a method for improving an electronic glass reinforced size expansion phenomenon and a preparation method of reinforced glass. The method for improving the electronic glass strengthening size expansion phenomenon comprises the following steps of preparing a molten salt, and enabling the pH value of the molten salt to be smaller than 7; and carrying out chemical strengthening on the electronic glass to be strengthened in the molten salt. The phenomenon of electronic glass size expansion caused by chemical strengthening is fundamentally improved. 本发明涉及电子玻璃加工的技术领域，特别涉及改善电子玻璃强化尺寸膨胀现象的方法和强化玻璃的制备方法。所述改善电子玻璃强化尺寸膨胀现象的方法，包括以下步骤：配制熔盐，使所述熔盐的pH值＜7；于所述熔盐中对待强化的电子玻璃进行化学强化。从根源上改善了化学强化造成的电子玻璃尺寸膨胀的现象。
