Vacuum fire-resistant glass

Abstract

The invention discloses vacuum fire-resistant glass. A glass original film in the vacuum fire-resistant glass is one of high-boron plate glass, high-boron toughened glass, caesium potassium fire-resistant glass, twin polishing wired glass, sodium calcium plate glass, sodium calcium toughened glass, Low-E plate glass and Low-E toughened glass, the vacuum fire-resistant glass is formed by compounding two kinds of the glass original film, a vacuum layer is formed between two sheets of glass, supporting objects fixed on the glass original film are evenly distributed in the vacuum layer, the thickness of the vacuum layer is 0.15-0.3mm, a ring of melting sealing layer formed by melting low-melting-point lead glass at the high temperature is arranged between glass, an air exhausting hole is arranged on the melting sealing layer, getter is arranged in the vacuum layer, and the getter is placed in grooves or holes arranged on the glass original film. The vacuum fire-resistant glass has functions of fireproofing, heat insulation and energy saving.

Description

technical field [0001] The invention belongs to the technical field of glass products, and in particular relates to a vacuum fireproof glass. Background technique [0002] At present, the domestic fireproof glass adopts wired glass, cesium potassium fireproof glass, etc. to be bonded or poured into composite glass through 2 to 3 layers of glass, and its energy-saving effect and impact resistance are poor. Fire resistance and impact resistance are also not ideal. [0003] For the vacuum glass that can overcome the technical defects of fireproof glass and insulating glass, it has the advantages of high thermal resistance, anti-condensation and frosting performance, good sound insulation performance, high wind pressure resistance, and long service life, etc., and conforms to the country's vigorously advocated Energy-saving policy, so it is widely used. [0004] However, in the actual use of vacuum glass, due to the residual air in the sealing interlayer during processing and ...

AI Technical Summary

Problems solved by technology

[0004] However, in the actual use of vacuum glass, due to the residual air in the sealing interlayer during processing and the desorption of gas on the surface of the glass during the service life, the vacuum degree in the glass will gradually decrease, which will affect the actual use effect and life of the vacuum glass. The material of vacuum glass is still insufficient in terms of energy saving and heat insulation.
