AI Technical Summary
Existing glass products are prone to generating a large number of fragments and high-kinetic-energy fragments when they break, leading to safety hazards. Existing chemical strengthening methods are difficult to achieve an ideal stress distribution to reduce fragments and fragment kinetic energy.
By controlling the stress distribution of glass-based products, the maximum compressive stress, compression depth, and central tension are ensured to be within a specific range. Combined with negative curvature regions, a suitable stress distribution is formed to reduce fragmentation and fragment kinetic energy.
It reduces the number and kinetic energy of glass fragments when glass products break, improving safety and durability, and is suitable for cover plates or windows of consumer electronics products.
