A chemical
tempering method for ultrathin unequal-thickness glass belongs to the technical field of chemical
tempering methods for ultrathin glass, and comprises the following steps: 1) covering the surface of an equal-thickness area of the unequal-thickness glass with a PET film for protection, and then
coating the upper surface of the unequal-thickness area of the unequal-thickness glass with a film for protection; 2) putting the coated unequal-thickness glass into a
tempering liquid for tempering treatment, so that the stress
layer thickness of a tempered unequal-thickness area is 6-8 microns, the stress value is 500-600MPa, the stress
layer thickness of a tempered uniform-thickness area is 10-12 microns, and the stress value is 650-750MPa; and (3) carrying out film stripping, cleaning,
drying, inspection, packaging and delivery on the tempered unequal-thickness glass cooled to normal temperature. The method has the beneficial effects that the non-uniform-thickness area of the unequal-thickness glass is subjected to
film coating protection, so that an effect of blocking part of
ion exchange in the chemical tempering process is achieved, so that the ultra-
thin glass has excellent bending performance, high
impact resistance and scratch resistance.
