Silver lithography glass processing method

Silver lithography glass processing method: First, the plate glass was washed with clean water and then completely coated with paraffin. Then, various patterns were engraved on the paraffin, and the glass surface was corroded with a 1:5 hydrofluoric acid solution. Finally, the hydrofluoric acid is removed and paraffin wax is removed, and the glass is […]

Glass Production Process

Production Process mainly include: 1 raw material processing. The crushed raw materials (quartz sand, soda ash, limestone, feldspar, etc.) are crushed, the wet raw materials are dried, and the iron-containing raw materials are iron-removed to ensure the quality of the glass. 2 batch material preparation. 3 melting. The glass batch material is heated at a […]

Automotive laminated glass

Laminated glass refers to the use of a transparent adhesive plastic film affixed between two or three layers of glass, combining the toughness of the plastic with the rigidity of the glass, increasing the resistance of the glass to crushing, still broken after Visibility can be maintained. Used for car windshields.

Silicate glass

Silicate glass refers to glass whose basic component is SiO2. It has many varieties and is widely used. According to different content of SiO2 and alkali metal and alkaline earth metal oxide in glass, it is divided into: 1.Quartz glass. SiO2 content is more than 99.5%, thermal expansion coefficient is low, high temperature resistance, good […]
