Production method of concave glass

Abstract

A method for manufacturing deep-etching patterned glass comprises the following steps: firstly, plate glass is cleaned and dried in the air; the plate glass is treated with corundum-sand blasting, and then the glass is placed on a silk screen provided with patterns in advance and is printed; after printing ink is dried in the air, the glass is vertically placed in a corrosion box filled with corrosive liquid to be soaked; then, the glass is cleaned, and the cleaned glass is placed in a box filled with sodium hydroxide solution; the glass is cleaned again, and the printing ink is removed; after being cleaned and baked, a finished product is manufactured. The pattern concave surface of the glass manufactured by the method is smooth, the edges are glidingly, and the edges have no saw tooth. In addition, the manufacture method is simple, the manufacturing cost is effectively lowered, and the method is favorable to environmental protection.

Description

technical field [0001] The invention belongs to the field of glass deep processing, in particular to a method for producing concave glass. Background technique [0002] The domestic invention patent authorization publication number is CN1179899C, and the patent number is ZL 02109830.1, which discloses the production method of concave glass. It adopts the method of acid corrosion combined with screen printing drawing to process on flat glass, which plays a positive role in the production of concave glass. effect. However, the corrosive liquid formula used in this production method makes the printed pattern rough, with occasional large areas of jagged concave and edge lines, which are not refined, have no three-dimensional sense and layering, and are not artistic and effective. And because the corrosive liquid formula contains a relatively large amount of hydrofluoric acid, not only the cost is too high, but also the air pollution is relatively serious. In order to reduce the...

However, the corrosive liquid formula used in this production method makes the printed pattern rough, with occasional large areas of jagged concave and edge lines, which are not refined, have no three-dimensional sense and layering, and are not artistic and effective.

And because the corrosive solution formula contains a relatively large amount of hydrofluoric acid, not only the cost is too high, but also the air pollution is relatively serious. In order to reduce the amount of volatile substance hydrofluoric acid, it is beneficial to environmental protection and overcomes the problems in the production process. There is an urgent need for a new concave glass production method
