Engraving glass is divided into artificial engraving and computer engraving. Among them, the artificial engraving uses the combination of the depth and the turning of the knives, which can better express the texture of the glass, and make the painted pattern give people the feeling of coming out. Engraved glass is a kind of decorative glass that is very tasteful in home decoration. The painted patterns generally have a personality “creativeâ€, reflecting the taste and pursuit of the owner of the room.
definition
Engraving glass: As the name implies, it is to engrave various patterns and characters on the glass. It has a strong three-dimensional effect and can be made transparent and impervious. It is suitable for partitioning and styling.
Production Process
The glass with the characters, patterns and patterns is used as an ornament, which is beautiful and elegant. The way to achieve this is to use the engraving method, which uses a chemical agent, an etchant, to erode the engraved glass. As an etchant, hydrofluoric acid has long been used. As an etching method, the glass to be engraved is washed, air-dried, and a paraffin liquid melted with gasoline is applied thereon as a protective layer, and a desired character or pattern is engraved on the cured paraffin layer. When engraving, the paraffin layer must be carved to expose the glass. Then, hydrofluoric acid [1] is dropped on the text or pattern of the exposed glass. According to the depth of the desired pattern, after controlling the corrosion time for a certain period of time, the paraffin and hydrofluoric acid are washed away with warm water to obtain a glass with a beautiful pattern. Although this method has been used for a long time, due to the volatilization of gasoline and hydrofluoric acid, the pollution is serious; the protective layer is needed, and the operation is complicated. The etched glass is etched by an etchant containing ammonium fluoride as an active ingredient, and the etching process does not require a protective layer, and the pollution is small and the operation is easy.
Features:
1. Using a special etchant with ammonium fluoride as an active ingredient, the pollution is less and the operating environment is greatly improved.
2, no need for protective layer, not only can save paraffin and gasoline, but also reduce manufacturing processes and improve efficiency.
3, the use of etchant, easy to obtain raw materials, simple to prepare, easy to use.
4. Compared with the past, the obtained etched glass has good quality and low cost.
use:
Etched glass can be used as store size, family plaque, decorative items, and unit awards. Etched glassware should be used as crafts and daily utensils for decoration and daily use.
