The immersion method is the traditional method of AG glass production, the method is further divided into:
Vertical Immersion Method
The use of underground digging pools or above-ground PVC pools, with aerial cranes for operation, an operating surface of at least not less than seven pools, each pool into the water, pickling solution, sand masking solution, polishing solution, etc. After pretreatments such as water washing and acid washing, the glass enters the sandblasting pool for sandblasting and etching treatment, and the glass after sandblasting is made into AG glass after the water washing and polishing thinning process.
Manual Horizontal Immersion Method
The glass is placed on a table on the ground with a height of about 400-500mm, and then placed on a special shelf and fixed after the glass is cleaned by acid washing. two workers carry the shelf and let the glass enter the sandblasting liquid with an inclination angle of 15-20 degrees, shake for a while, and then stand still, and then lift it up to clean it with water.
Automatic Line Horizontal Immersion Method
The glass is cleaned by pretreatment and transported to the drive belt, which is about 10mm deep in the etching solution, the glass is immersed in the potion and pulled by the drive belt, and after the reaction time is up, the potion on the glass surface is washed off with water and the polishing and the thinning process is carried out directly.
The drenching method is to drench the masking solution onto the glass surface through certain equipment, specifically classified as follows.
The horizontal automatic line coating method
Curtain-type drenching is used, and only one curtain is needed for the sanding section. The glass is cleaned through the pretreatment and passed through the curtain quickly, and the speed returns to normal after the glass passes through the curtain. After a certain time of reaction of the chemical water, the chemical water is recovered. After cleaning, the glass enters the polishing section for the polishing and thinning process, and the polishing section and the sanding section are linked in a horizontal polishing process.
Inclined automatic line drenching method
This method is also a popular method of AG glass production, the most important feature is that the whole line of the sand masking section is not horizontal, but with a certain angle, generally at 5~15 degrees.
