Dual composite coated transmittance glass

Abstract

The invention discloses a dual composite coated transmittance glass comprising a silicon dioxide glass substrate and transmittance films arranged on the surface of the silicon dioxide substrate. The silicon dioxide glass substrate has a two-layer structure, and comprises an upper-layer silicon dioxide glass substrate on an upper layer and a second silicon dioxide glass substrate on a lower layer. The first and second silicon dioxide glass substrates both have a square structure. An infrared transmittance film is arranged on the upper surface of the first silicon dioxide glass substrate, and an ultraviolet transmittance film is arranged on the lower surface of the second silicon dioxide glass substrate. The glass has a simple structure. Through rotation adjustment, various different application effect can be obtained. The glass is convenient to use, and has a good application effect.

Description

technical field [0001] The invention relates to the field of functional glass, in particular to a double composite coated light-transmitting glass. Background technique [0002] Glass is an amorphous solid with a random structure. Its molecules do not have a long-range order in space like a crystal, but a short-range order similar to a liquid. Glass retains a specific shape like a solid and does not flow with gravity like a liquid. Glass is generally made of quartz sand, soda ash, feldspar and limestone, etc., after mixing, high-temperature melting, homogenization, processing and forming, and then annealing. Glass can be divided into embossed glass, forged glass, crystal glass, glazed glass, wired glass, polycrystalline glass, glass mosaic, tempered glass, laminated glass, insulating glass, dimming glass or luminous glass according to the process method. In construction, optics, daily use, medical treatment, chemistry, electronics, instrumentation, nuclear engineering and ...

Problems solved by technology

[0003] Most of the glass used in the prior art has a single function and can only pass through sunlight. For different light requirements, different coating materials need to be added, which is more troublesome to use
