Protective glass

Protective glass refers to the glass that can protect people from strong light, heat and radiation. There are many kinds of glass, mainly including: (1) The glass that absorbs ultraviolet and some visible light is generally gray, and dichromate and iron oxide are added to the powder during manufacturing; (2) The glass absorbing infrared ray and part of visible light is generally blue-green, and nickel oxide and ferrous oxide are added to the powder during manufacturing; (3) The glass that absorbs ultraviolet, infrared and most visible light is generally dark blue-green. Ferrous oxide, dichromate and nickel oxide are added to the powder during manufacturing; (4) Glass absorbing X-rays and 7-rays, containing a large amount of lead oxide; (5) The glass absorbing neutron current contains a certain amount of cadmium oxide and boron oxide. The protective glass is widely used in high-temperature operations such as electric welding and steel making, X-ray instruments and equipment, peaceful use of atomic energy and space flight.

The utility model comprises a glass substrate, which is characterized in that one side of the glass substrate is provided with an anti-reflective protective film, and the other side is provided with a conductive film. The utility model is simple in structure, practical and easy to popularize, and has a large market demand.
