Abstract
The invention discloses a glass lens processing method which sequentially comprises the steps of coarse grinding, elaborate polishing, reinforcing, acid treatment and after-polishing, wherein in coarse grinding, a copper disc or tin disc jumping within 0.1mm is adopted for coarse grinding; in elaborate polishing, a polishing solution with a polishing powder diameter below 1 micron is adopted for polishing the product; in reinforcing, analytically-pure fused potassium nitrate is adopted for chemically reinforcing the product; in acid treatment, the lens is soaked in mixed acid of hydrofluoric acid, sulfuric acid and water at a ratio of 1:1:50 for 2.5-3.5 minutes at 34-37 DEG C while the solution is oscillated and circulated; in after-polishing, a polishing solution with a polishing powder diameter below 0.8 micron is adopted for polishing the product. In the method, SiO2 in the glass reacts with acid, thus the stress concentration is reduced or eliminated, the glass strength is enhanced, the scratch rate of the glass is reduced, and the light transmission and appearance beauty are improved.
Description
Technical field
Present method relates to the manufacture field of glass mirror, particularly a kind of glass mirror working method and the mixing acid for the treatment of glass mirror.
Background technology
Along with the continuous renewal of mobile phone, MP3, MP4 etc. electronic product is regenerated, it is thinner, lighter that product trends towards, and is used for doing the intensity, transmittance of the glassy product that form uses etc. aspect simultaneously and requires also more and more higher.For making thinner glass have larger shock resistance, anti-extrusion, high transmittancy, increasing glass mirror polishing, grinding and reinforcing process are there is.
All glass, in cold working process, all can cause more or less, dark or shallow hair line, and the tiny crack shape of these V-shapes is sharp-pointed, is being subject under certain extruding, impact forces, is easy to rupture along cracks.Meanwhile, due to the existence of V-shape tiny crack, glassy product even has the risk of self-destruction after strengthening.
Acid treatment process is only limited application in glass processing industry, and reason is to be difficult to find a kind of manufacturing process of the best, effectively prevents from scratching, the residual corrosion washmarking of product contact chucking position.
Summary of the invention
The invention provides and a kind of in traditional glass eyeglass cold working process, increase acid treatment process for the deficiencies in the prior art, reach a kind of glass mirror working method that improves glass shock resistance, anti-extrusion, high transmission rate effect.
The present invention has taked following implementation method, in turn includes the following steps: corase grind, smart throwing, strengthening, acid treatment and return throwing;
Described strengthening adopts analytical pure saltpetre fused salt to carry out chemical enhanced to product;
Described acid treatment is, at 34 DEG C-37 DEG C, eyeglass is immersed in to hydrofluoric acid: in the mixing acid of sulfuric acid: water=1:1:50 2.5-3.5 minutes, and vibration, circulate soln simultaneously;
The described polishing fluid of throwing employing polishing powder footpath below 0.8um that return carries out polishing to product.
Described vibration is that upper and lower amplitude is that 5mm or left and right amplitude are 5mm concussion, and the solution circulation rate of described circulate soln is 1m
3/ min.
Described corase grind adopts the card 0.1mm that beats to roughly grind with interior copper dish or tin dish;
Described essence is thrown and is adopted the polishing fluid of polishing powder footpath below 1um to carry out polishing to product;
For the treatment of a mixing acid for glass mirror, formed by hydrofluoric acid, sulfuric acid and water, mass ratio is hydrofluoric acid: sulfuric acid: water=1:1:50.
Described oscillation method is that amplitude is upper and lower 5mm or left and right 5mm; Described solution circulation rate is 1m
3/ min.Amplitude is too small, and solution circulation rate is too small, and composition residual after acid treatment cannot effectively be removed; Amplitude is excessive, and solution circulation rate is excessive, can cause product shake large, and when serious, product may depart from workpiece, causes collision to scratch, and therefore amplitude is that upper and lower 5mm or left and right 5mm can effectively remove residual composition after acid treatment, can not cause again product shake large.
Present method adopts hydrofluoric acid: the mixing acid of sulfuric acid: water=1:1:50, at 34 DEG C of-37 DEG C of temperature, glass immersion is processed to 3Min, and can significantly improve strength of glass, glass transmittance, this technique drops into little, instant effect, production capacity is high.
Present method takes to increase acid treatment process, makes the SiO in glass
2react with acid, reduce or eliminate stress concentratedly, improved strength of glass, reduced the cut rate of glass, improved light transmission and aesthetic appearance.
Brief description of the drawings
Product four-point bending intensity contrast after the acid treatment of Fig. 1 different concns.
Product Ring On Ring contrast after the acid treatment of Fig. 2 different concns.
Before and after Fig. 3 acid treatment, product transmittance changes.
