Embodiment Construction
[0021] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered by the claims.
[0022] see figure 1 , the present invention removes the glass surface compressive stress (CS) by chemical ion exchange, and the steps are as follows: the strengthened glass is first preheated, and then transferred to a glass equipped with NaNO 3 High-temperature ion exchange is carried out in the mixed solution of the glass, so that K in the glass + with Na in solution + Substitution is carried out to make the smaller ionic radius Na in the solution + Replaces K with larger ionic radius in glass + , in order to achieve the purpose of removing the compressive stress on the glass surface, the reaction principle formula is as follows:
[0023] K + 玻 +Na + 液 →Na + 玻 +K + 液
[0024] The specific implementation is as follows:
[0025] The first ste...
