REXI glass etching is the application of a special effect on the glass surface. Glass can resist many kinds of acids, but phosphoric acid and hydrofluoric acid can easily corrode and polish the surface, creating a fluffy texture.
Glass etching is the technique of etching and printing directly on the surface of the glass by means of screen plates, frosting pastes and other materials. The surface becomes opaque due to chemical reactions.
The products can be roughly divided into four kinds of effects from particle size, whiteness and smoothness: general effects, jade sand effects, low reflection effects, and fingerprint-free effects. Glass etching price of the four effects are different.
The use of hydrofluoric acid to etch in China glass etching factory is extremely dangerous. It can injure human skin and even bones. The volatile gases are toxic and corrosive. Therefore, the etching must be done with care and professional washing equipment, including protective hoods for corrosive gases. Wide mouth plastic containers are suitable for storage space and working equipment, plastic ladles are very useful tools, but China glass etching manufacturers can also use metal spoons after wax wrapped. Workers should wear protective clothing, protective boots and a face mask when handling acids. It is recommended to use alkaline neutralizing equipment to solve emergencies.
The depth and effectiveness of corrosion depends on the acid strength and the soaking time. It needs to adjust the etching method according to different conditions. In general, 60% hydrofluoric acid are universally applicable. If you want to go deep etching, you need hydrofluoric acid in higher concentration to remember. China glass etching suppliers warns: the acid must be added to the water instead of adding water to the acid for your safety!
