Detailed Description
A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
The Anti-glare glass is also called AG glass (Anti-Glare glass), and is characterized in that the reflection surface of the original glass is changed into a matte diffuse reflection surface, so that the reflection image can be blurred, the reflection degree is reduced while glare is prevented, light shadows are reduced, the surface of the Anti-glare glass is strong in corrosion resistance and scratch resistance, frosted touch feeling is realized, and the probability of breakage caused by easy slipping of a hand held by terminal electronic equipment such as a mobile phone and the like is reduced.
The AG process is roughly divided into three types:
(1) flash sand AG process: through special chemical process treatment, the original glass reflective surface is changed into a matte diffuse reflective surface, so that a reflective image can be blurred;
(2) coating AG process: covering a specific coating material on the surface of the glass by an atomization coating technology;
(3) and (3) AG spraying process: and spraying a layer of optical light scattering particles on the surface of the glass by equipment.
In the prior art, the process flow for producing curved-surface AG glass by the flash sand AG process is generally as follows: glass raw material-cutting (single chip) -CNC-SPM polishing and cleaning-hot bending-CNC-concave and convex surface scanning-concave surface acid-resistant protective oil spraying-surface oil wiping-flash sand AG-deinking-chemical polishing-cleaning-strengthening.
The improved process of the invention comprises the following steps: glass raw material-cutting (multi-piece typesetting, as shown in figure 1) -back screen printing acid-proof protective oil (as shown in figure 2) -glittering sand AG (as shown in figure 3) -de-inking (as shown in figure 3) -chemical polishing (as shown in figure 3) -CNC (as shown in figure 4) -SPM polishing and cleaning (as shown in figure 5) -hot bending (as shown in figure 6) -concave surface scanning-cleaning-strengthening.
The conventional process comprises the steps of carrying out CNC machining, hot bending and acid-resistant protective oil spraying on a single piece of glass, and then carrying out AG process on the glass by using flash sand to obtain the anti-dazzle curved glass.
In contrast, the process of the invention comprises the steps of firstly, silk-screening acid-resistant protective oil on the back surface of glass, carrying out AG process of flash sand, and then carrying out CNC machining and hot bending on the glass; because the hot bending is carried out later, the flat glass can adopt larger middle glass, and the flat glass is divided into single glass in size and then is subjected to hot bending, so that the efficiency can be improved.
After the glass is subjected to the flash sand process, AG particles and patterns are arranged on the surface of the glass; but the glass can be subjected to hot bending after being softened, but patterns and particles are easy to erase when the hot bending pressure is large or the temperature is high.
Acid-proof protective ink and oil mist generated in the spraying process of the original process are easy to splash to the convex surface of the curved glass, and when the flash sand AG process is subsequently performed on the convex surface, the phenomenon of bad bright spots can occur locally due to the fact that the chemical reaction can not occur due to the shielding of the acid-proof protective ink. Therefore, before the flash sand AG process is carried out, oil mist and printing ink splashed to the convex surface need to be manually checked and wiped, and the omission detection is easy to occur; and the glass is easy to crack after being manually wiped in an untempered state, so that the manufacturing difficulty of the AG glass is increased, and the yield is reduced.
The invention adopts the middle-sized plain glass, carries out the flash sand AG process, then carries out 3D hot bending, and replaces the mode of spraying acid-resistant protective oil with silk screen printing, thereby avoiding the surface oil wiping manpower required by ink overflow and ink aerial fog splashing caused by spraying, and reducing the consumption of ink (the same silk screen area, the sprayed ink is 1.5-2 times of the consumption of the silk screen printing ink); simultaneously, experimental design verification is carried out: after the flash sand AG process, the glass is thermally bent, and the convex surface of the curved glass does not sweep light and basically does not influence the anti-glare effect; compared with the prior art, the process disclosed by the invention can comprehensively save the cost of more than 5 yuan for each piece of curved glass.
The middle piece of glass is larger than a single piece of glass and can be divided into a plurality of single pieces of glass; in a specific embodiment, the glass sheet can be divided into 3-5 single glass sheets.
SPM solution, namely mixed solution of sulfuric acid and hydrogen peroxide.
Deinking, namely removing the acid-resistant protective oil on the glass surface.
