Bearing capacity is one of the core indexes to measure the safety performance of glass. The strength of traditional physical tempered glass is improved by surface compressive stress, but its stress layer is relatively shallow and there is a tensile stress zone. Once the surface is broken (such as being hit by a sharp object or generating deep scratches), the whole structure is prone to catastrophic crushing. The excellent impact resistance of Ming dun ion tempered glass stems from its unique "embedded extrusion stress" mechanism. In the process of ion replacement, larger potassium ions "squeeze into" the silicon-oxygen network structure on the glass surface, occupying the original position of sodium ions. This "embedding" action leads to the outward expansion force of the glass surface network structure, thus forming a continuous and deep compressive stress field on the surface. This stress field is "embedded" in the material, and the depth is usually several times that of physical tempering. When the external impact load acts on the glass, its energy is first effectively absorbed and dispersed by this deep and high-strength compressive stress layer. Compared with physical tempered glass, Ming-dun ion tempered glass needs more energy to overcome this layer of "defense", thus improving its bending strength, impact strength and surface damage resistance geometrically. The experimental data show that its impact resistance can reach 3-5 times or even higher than that of ordinary physical tempered glass. This performance leap brought by the basic principle enables Ming Shield glass to withstand more severe impact and higher load, and provides a stronger barrier for people and property under extreme conditions such as strong wind, hail and even accidental impact.
