The main potassium nitrate solution and collocation based on 3mm thickness glass below, using high-purity of chemically toughened glass
Catalyst be mixed and heated to 420 degree Celsius or so, the potassium ion and sodium ion on glass structure surface carry out ion exchange and shape
At strengthening layer, the lesser Na+ of glass surface radius is exchanged with the biggish K+ of radius in stiffened solution, glass surface expansion, in glass
Two surfaces of glass form extrusion stress layer, form tensile stress layer in inside glass, achieve the purpose that improve strength of glass.
But after chemically enhancing glass, because there are extrusion stress layers on two surfaces of glass, such as surface of the glass after reinforcing
When generation scuffing, wiping flower, sags and crests etc. are bad, directly progress fine-grinding and polishing reparation will lead to glass deformation, and apparent flaws are repaired
Multiple efficiency is extremely low.It is scrapped so the glass defective products after reinforcing can only move back storehouse, causes the waste of a large amount of human and material resources resources.
Glass after chemical strengthening, there are extrusion stress layer, directly fine grindings to do over again on surface, is primarily present following problems:
(1) in the case where refiner polishes shear action, the stressor layers removal amount of glass surface each position is inconsistent, has upset glass
The stress equilibrium on glass surface, leads to glass deformation；
(2) glass after chemical strengthening, Surface stress layer is close, and intensity is high, and refiner polishes the effect of faulty restoration flaw
Rate is very low.
