Abstract
The invention discloses a technology for machining float glass protection cover plates with a low warping degree. The technology includes the processes of raw material glass preparation, surface treatment, cutting, shape milling, washing, surface polishing and thinning, washing and chemical tempering. By performing surface polishing and thinning treatment on float glass, glass with stanniferous face removed is obtained, so that the ion exchange amounts of the upper face and the lower face of the large-size float glass in the chemical tempering process are the same, same stress is generated, the warping degree of the tempered glass is reduced, and the flatness of the glass is improved.
Description
Technical field
The present invention relates to a kind of processing technology that reduces large scale float glass cover sheet angularity.
Background technology
Float glass is the production method of the flat glass that is most widely used at present, and the glass of its production has and there is no brush line, and Pingdu is good; even thickness; close structure, the advantage that feel is level and smooth, what the surface protection cover plate of the touch control devices such as current mobile phone and computer generally adopted is exactly float glass.The technological process of processing float glass cover sheet is at present that former material glass à surface treatment à sawing sheet, milling profile à clean à chemical tempering; but the sodium ion in chemical tempering process in itself and non-tin face of the tin face of float glass and potassium ion reaction rate and the exchange capacity in potassium nitrate are inconsistent; cause its upper and lower surface stress inconsistent, its surface can produce warpage.When glass size hour, its stress difference is little, angularity is less; After glass size increases, because upper and lower surface stress difference increases, its angularity can obviously increase, and causes glass surface flatness bad, causes bad order.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: proposed a kind of processing technology that reduces large scale float glass cover sheet angularity.
Technical solution of the present invention is achieved in that the processing technology of the float glass cover sheet with low warpage, and described technological process is: former material glass à surface treatment à sawing sheet à milling profile à cleans à surface finish attenuate à and cleans à chemical tempering.
Preferably, described surface finish reduction process step is as follows:
1) polishing powder is deployed into polishing fluid;
2) epoxy resin pleasure boat tool is placed on polishing disk;
3) will after milling profile, put into pleasure boat tool through the float glass cleaning;
4) start polissoir, float glass is carried out to surface finish reduction processing.
Preferably, in polishing card, be provided with felt or pitch or nonwoven or polyurethane or politef.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The processing technology of the float glass cover sheet with low warpage of the present invention; make Float Glass Surface attenuate by surface finish reduction processing; the glass of stanniferous is eliminated; thereby can make the ion exchange capacity of large scale float glass top and bottom in the time of chemical tempering identical; produce identical stress; after reduction chemical tempering, the angularity of glass, improves glass flatness.
Brief description of the drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is process chart of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
The processing technology of the float glass cover sheet with low warpage of the present invention
,described technological process is: former material glass → surface treatment → sawing sheet → milling profile → cleaning → surface finish attenuate → cleaning → chemical tempering; Wherein surface finish reduction process principle: be exactly to utilize the ablation of polishing powder and the aquation of glass surface and water to process Float Glass Surface.The process of lapping of glass before this mill and glass surface is done relative motion, the mechanism that Free Abrasive carries out cut and peels off glass surface under mill load, thereby be eliminated the glass of stanniferous, thereby can make the ion exchange capacity of large-size glass upper and lower surface in the time of chemical tempering identical, produce identical stress, after reduction chemical tempering, the angularity of glass, improves glass flatness.
Surface finish reduction process step of the present invention is as follows:
1) polishing powder is deployed into polishing fluid;
2) epoxy resin pleasure boat tool is placed on polishing disk;
3) will after milling profile, put into pleasure boat tool through the float glass cleaning;
4) start polissoir, first adopt light pressure: 125KG, 5min, is using weight: 250KG, 25min, and rotating speed is: 20rmp, carries out surface finish reduction processing to float glass.
The glass of processing through surface finish reduction process is cleaned, then the glass after cleaning is carried out to chemical tempering.
In polishing card, be provided with felt or pitch or nonwoven or polyurethane or politef; The kind of polishing powder has: iron oxide, and cerium oxide, lanthana, titanium oxide, zirconia, aluminium oxide, chromium oxide and thorium oxide etc., the soft polishing powder of property for soft flint glass, as cerium oxide; The hard polishing powder of property for the Pyrex of hard and quartz glass, as zirconia.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
