Introduction of high borosilicate fireproof glass
The BTG borosilicate monolithic fireproof glass is formed by tempering an original piece of glass produced by a high borosilicate floatation process. Its fire resistance is derived from its very low coefficient of thermal expansion - only 4 x 10 -6 (20-300 ° C), which is 2 to 3 times lower than ordinary glass (silicate glass). In addition, BTG borosilicate monolithic fire-resistant glass also has a high softening point, excellent thermal shock resistance and viscosity. Therefore, when a fire occurs, the BTG borosilicate monolithic fireproof glass is not easily expanded and broken, and is a high stability single piece fireproof glass with a fire resistance time of up to 3 hours.
Thickness | Common size | Weight | Fireproof time | Transmittance | Soundproof |
6mm | 2440*1830、2000*1830 | 13.7 kg/㎡ | C30-C180 | 90% | 30dB |
8mm | 2000*1830 | 18.2 kg/㎡ | C30-C180 | 90% | 30dB |
Advantages of high borosilicate fireproof glass
1. 4×10 -6 (20-300°C) thermal expansion coefficient, 2-3 times lower than ordinary glass (silicate glass), creating over 3 hours of fire prevention time
2. 851 ° C ultra-high softening point, escort for fire stability
3. No Nis crystallization, sweeping away the danger of self-explosion
4. Fully tempered single piece fire resistant glass for double safety requirements
5. 90% high light transmittance, low iron formula to meet the true color rendering
6. Superior borosilicate optical quality for undistorted visuals
7. 2.28g/cm3 (25°C) density, low self-weight to keep small body
9. Ultra-high mechanical strength makes it light and contains unlimited power
10. Good corrosion resistance, stable and not afraid of UV
Application of high borosilicate fireproof glass
1. Fire resistant window
2. Fireproof partition
3. Fireproof curtain wall
4. Smoke blocking wall
5. Skylight, fireproof floor
