TENSILE STRESS APPLYING TYPE GLASS HOLDER AND CHEMICAL STRENGTHENIGN METHOD OF GLASS USING THE SAME

摘要

In chemical strengthening treatment of glass, chemical strengthening treatment is performed in a state where tensile stress is applied to glass by using a glass holder, so that ion exchange of glass proceeds more easily and compressive stress of glass surface increases after chemical strengthening treatment, To a tensile stress applied type glass holder and a method of chemical strengthening treatment of glass using the same. A tensile stress applied type glass holder according to the present invention includes: a support frame having a plurality of fastening holes which are opened along at least one side to face a plurality of glass for chemical strengthening treatment; A glass support mounted along the long side of the support frame and having a plurality of insertion grooves for seating the plurality of glasses; A grip member coupled to each of the plurality of fastening holes of the support frame for gripping both side short sides of the glass that are respectively seated on the glass support; And a tightening member mounted on an end of the grip member and applying a tensile stress to the glass by tightening the grip member.
