The invention has the beneficial effects as follows: the present invention, by glasswork is carried out to acid corrosion processing, can significantly improve the resistance to impact shock of glass; In addition, due to the two-sided consistency of thickness that is placed in same environment Zhong， two sides removal of glasswork in acid corrosion process, can there is not modification and break in glass, thereby improved the good article rate of glass.
Embodiment
Glass strengthening method of the present invention need to be carried out acid corrosion processing to glass, carrying out acid corrosion processes to be placed on glass is carried out before chemical tempering processing, also after can being placed on glass being carried out to chemical tempering processing, can also carry out chemical tempering process before with all to glass, carry out acid corrosion processing afterwards.
Wherein, before being carried out to chemical tempering processing, glass carries out acid corrosion processing also referred to as the pre-treatment of glass surface, object is before chemical tempering, farthest to remove the defects such as the tiny crack on glass surface and sub-surface, scuffing, prevent glass in chemical tempering process because thermal shocking causes crack growth.In addition, because acid corrosion processing makes the H in acid
+na with glass surface
+there is ion-exchange, the rich H of glass surface
+, when glass carries out chemical tempering, the K more easily and in fused salt
+exchange, thereby can exchange by speeding-up ion, chemical tempering promoted.
The concrete grammar that above-mentioned acid corrosion is processed is: the glass processing is put in the acid tank that treatment solution is housed, treatment temp is at 20-30 ℃, and the treatment time is 10-20 minute.The component of the treatment solution adopting and content are: the H that the HF acid that concentration is 1-10mol/L and concentration are 1-6mol/L
2sO
4, the ratio of 1:1 preparation by volume.In order to make corrosion more even, in acid tank, be preferably provided with bubbling device, after corrosion, the corrosion thickness on glass two sides is all 20-50um, optimum thickness is 25-40um left and right, poor being controlled in 0.05mm of corrosion thickness on glass two sides.
