Product technologyIntroduction
In the processing technology dimension, it covers spraying AG, coating AG and chemical etching AG three types. Spraying AG relies on a spray gun or dish atomizer to evenly spread optical astigmatism particles on the glass surface with the help of pressure or centrifugal force to build a coating to achieve anti-glare effect. This process is simple, fast and efficient, and can easily shape finished products with different gloss and fog degrees, but its particle fineness is poor, the control range of gloss and roughness is limited, and the AG layer is easy to peel off, and the friction resistance is weak.
Coating AG uses atomization coating technology to attach specific coating materials to the glass surface, and achieves anti-reflection and anti-glare goals by means of a clever combination of light, absorption and deflection. However, the hardness of the glass produced by the process is constant, it is easy to scratch after use for a while, the handwriting touch is unsatisfactory, the application scope is relatively narrow, and at this stage, it is more common in the rearview mirror, a small amount of TV screen glass and navigation instrument glass. Chemical etching AG is a mixed acid preparation of HF hydrofluoric acid as the main agent, which carries out chemical reaction etching on the main body of glass, and promotes the glass surface to change from a reflective state to a matte diffuse reflection state. The AG glass cast by this process not only has the characteristics of anti-glare and reduced reflection, but also has the excellent performance of anti-corrosion and anti-scratch, the etched surface particles are uniform, the roughness range is between 0.08-2.0, the gloss is up to 150, the transmittance is more than 20%-90%, and the product life is the same as that of general reinforced glass. Favored by the market, widely appeared in the car, pen, tablet and other consumer electronics industry.
Future outlook
It is true that AG glass is not perfect. The high cost has become a "roadblock" for its large-scale entry into the market, especially when the AG treatment is performed on curved glass, the cost is even higher. But there is no doubt that with the continuous advancement of technology and the increasing investment in research and development, these problems will eventually be solved, and AG glass will shine in more fields and outline more wonderful for people's lives.

Looking from the application scenario, AG glass can be seen everywhere. In all kinds of displays and protective screens, it is like a "clear light messenger" to disperse reflective haze for users and help upgrade visual effects; In the mobile phone industry, many high-end flagship mobile phones such as Apple iPhone 11 Pro, OnePlus 7T Pro, Mi 9 Pro, Mi 10 Pro and OPPO Find X2 have chosen AG glass back cover. This kind of back cover with chemical etching process, showing a charming frosted texture, not only retains the smooth touch of glass, but also not easy to stain fingerprints, but also strengthen the anti-slip and anti-scratch performance, has become the current mobile phone design trend choice. And with the maturity of the process and the optimization of the cost, AG glass has gradually become popular in the low-end mobile phone market, such as Xiaomi's Redmi K30 5G mobile phone. In addition, the museum uses AG glass as an art protective cover, which not only ensures that the audience can clearly appreciate the cultural relics, but also avoids reflective interference; The advanced picture frame uses AG glass to add color to the painting and sublimate the display effect.
