Abstract:

The aging quality of solid masking powder is an important factor to determine the etching effect of glass.X-ray diffraction(XRD),energy dispersive spectrometer(EDS),Raman spectra,Viscometer,Zeta potential and alkali titration were used to study the change law of physical and chemical properties with the aging time of the masking powder mainly consisting of citric acid and ammonium bifluoride,and the effect of aging time on the etching effect of GG6 mobile phone cover glass was investigated and evaluated.The results showed that the viscosity and the hydrogen ion concentration of the suspension were the maximum when the aging time was 36 h.The leading roughness,haze,transparency and glossy of the etched glass were 265 nm,84%,92.4% and 11.7%,respectively,which met the etching quality requirements of industrial mobile phone glass cover plate.After etching,the GG6 glass surface had a layer of fluorosilicic acid crystal,which constituted a more uniform micro-nano pore structure.The determination of the physical and chemical properties of the masking liquid was helpful to better understand the curing process of frosted powder,and had a certain theoretical guidance for the etching process of frosted powder,so as to effectively improve the production efficiency of glass anti-glare process.

Key words: masking powder, cover glass, anti-glare, aging, etching
