Specific implementation mode
The present invention is further explained in the light of specific embodiments, so that those skilled in the art can be preferably
Understand the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
Embodiment one
Present embodiment discloses a kind of methods for improving warpage after chemically enhancing glass, after handling chemical intensification treatment
The glass of warpage occurs for surface, and the glass that warpage occurs after chemical strengthening has first surface and second surface, second when warpage
Surface outwardly convex, first surface on the other side are recessed inwardly so that the surface stress of first surface is less than second surface
Surface stress.
The disclosed method for improving glass warp of the present embodiment is：Change the surface stress of second surface so that the second table
The surface stress in face and the surface stress of first surface balance.
In the present embodiment technical solution, change the surface stress of above-mentioned second surface, above-mentioned glass by chemical etching technology
The first surface of glass is equipped with anti-corrosion film layer, corrodes the second of above-mentioned glass under 0~55 DEG C of corrosion temperature by corrosive liquid
Surface.In the strengthened glass raw materials of this implementation technical solution, including sodium oxide molybdena, the weight percent of sodium oxide molybdena is 2~
20%, the corrosive liquid for corroding strengthened glass is one kind and organic acid or inorganic acid in hydrofluoric acid, fluoride salt or both the above
Or the mixture of organic salt or inorganic salts.
The above corrosive liquid, can be in individual hydrofluoric acid, individual fluoride salt, hydrofluoric acid or fluoride salt one kind with
The mixture of organic acid or inorganic acid or organic salt or inorganic salts.
Improve the angularity of measurement strengthened glass before glass warp, corrosion using the ameliorative way of the present embodiment technical solution
The concentration of liquid, etching time change, the bigger etching time of angularity according to the angularity for measuring obtained current strengthened glass
It is longer, corrosive liquid concentration is bigger；Conversely, then etching time is shorter, corrosive liquid concentration is smaller.Corrosive liquid corrodes second surface
Deep-controlled at 0.3~100 micron, corrosion depth changes according to measured angularity and is changed, and angularity is bigger, and corrosion is deep
Degree is bigger；Conversely, it is then smaller, reduce the surface stress of second surface by chemical attack, is allowed to the surface with first surface
Stress equilibrium.
The first surface of glass is protected by anti-corrosion film layer while carrying out chemical attack to second surface, also
It is when reducing the surface stress of second surface, the surface stress of first surface is constant so that the surface stress of second surface and the
The surface stress on one surface balances so that the angularity of strengthened glass is the one thousandth of glass length, meets the use of glass
It is required that.
