Embodiment
Preparation method to glass reinforced method and OGS touch-screen is further detailed below in conjunction with accompanying drawing.
As shown in Figure 1, the glass reinforced method of an embodiment comprises the steps:
Step S110, the glass that adopts base exchange method to treat intensive treatment carry out primary reinforcement to be handled, and wherein, participates in the cationic radius of exchange greater than the radius of sodium ion.
The glass for the treatment of intensive treatment is silicate glass, and it contains sodium ion.In the present embodiment, glass is the corning glass that is used for touch-screen that Corning Incorporated produces.Certainly, glass can be the Asahi Glass glass that is used for touch-screen that Asahi Glass glass limited-liability company produces.
Owing to contain the sodium ion of positive monovalence in the glass, thereby the positively charged ion that participates in exchange is preferably the potassium ion that is all alkali-metal positive monovalence.Be appreciated that participating in the cationic of exchange can be other positively charged ions, as the rubidium ion of positive monovalence.
In the present embodiment, in the primary reinforcement treating processes, the cationite that adopts is the saltpetre fused solution, glass is soaked in handled in the saltpetre fused solution 6～7 hours, wherein, the temperature of saltpetre fused solution is 400～450 ℃, and the temperature of saltpetre fused solution is lower than the second-order transition temperature of glass (Tg).Aforesaid method can obtain the result of intensive treatment preferably in the short period of time, has higher industrialization production efficiency.The saltpetre fused solution also can be for the fused solution of other salt close with the saltpetre fusing point, as the fused solution of rubidium nitrate.
Be appreciated that in other embodiments, in the primary reinforcement treating processes, the cationite that adopts can be the saltpetre fused solution, applies saltpetre fusion liquid layer on two surfaces up and down of glass, then, be placed on and strengthen in the stove, in 400～450 ℃ of following intensive treatment 6～7 hours.
In the present embodiment, the reinforcement degree of depth that the primary reinforcement of glass is handled is preferably 20 μ m, can eliminate the tiny crack of glass surface preferably, does not influence the original performance of glass again, as, the light transmission of glass.
In the present embodiment, glass also comprises the step that glass is cleaned after primary reinforcement is handled.The step of cleaning is specially: adopt ultrapure water that glass is carried out spray Cleaning for High Capacity earlier, adopt ultrapure water that glass is carried out ultrasonic cleaning then, farthest remove and be attached to saltpetre on glass.
Step S120 carries out polished finish to the outer peripheral edge portion of the glass after handling through primary reinforcement.
Outer peripheral edge portion (the normally cut out portion of glass) to glass is carried out the tiny crack that the outer peripheral edges place of glass can be effectively eliminated in polished finish, realizes the purpose of reinforcing glass intensity.
Step S130 attaches anti-sorrel on two surfaces up and down of the glass after polished finish, carries out the secondary intensive treatment in the aqueous solution of hydrofluoric acid.
Adopt hydrofluoric acid that the outer peripheral edge portion of glass is carried out the secondary intensive treatment, destroy the silica film of outer peripheral edge portion, make the tiny crack of outer peripheral edge portion uniformly by etching off, or make crest truncation, the radius-of-curvature of tiny crack become big, thereby reduce the stress concentration phenomenon, further strengthen the intensity of glass.
The time of secondary intensive treatment can not be too short, can not be long.The time of secondary intensive treatment is too short, and strengthening effect may be undesirable.The overlong time of secondary intensive treatment, hydrofluoric acid may pass through osmosis, enters between anti-sorrel and the glass surface, and then the etching glass surface.And the time of secondary intensive treatment is relevant with the concentration of the aqueous solution of hydrofluoric acid.Therefore, in the present embodiment, the massfraction of hydrofluoric acid is preferably 5%～40%, and the time of secondary intensive treatment is preferably 5～20 minutes.
