Fireproof glass, the role of fire prevention is mainly to control the spread of fire or smoke, is a measure of fireproof material, its fire effect to fire performance evaluation. It is a special glass that has been processed and treated by special technology and can maintain its integrity and heat insulation in the specified fire resistance test. Fireproof glass can be divided into composite fireproof glass (perfusion type and composite type, grouting fireproof glass has good heat insulation performance, composite fireproof glass has good fire performance) and single piece of fireproof glass.
Composite fireproof glass is composed of two or more layers of glass with one layer or more layers of water-soluble inorganic fireproof glue interlayer.
Monolithic fireproof glass is a kind of fireproof glass with single-layer glass structure. Maintain fire integrity, open fire and toxic and harmful gases on the positive side of the fire for a certain period of time, but it does not have the effect of temperature insulation.
Borosilicate glass is a building fire glass upstart, invented by the German SCHOTT company in 1893, and widely used in many industries.
Borosilicate glass | ||
The expansion coefficient is halved, the temperature rise expansion is small, and the thermal stress is halved | Small change | Excellent fire resistance |
The strength is several times larger, supporting the thermal shock, carrying the greater thermal stress | Strong essence | |
High softening temperature, large viscosity, more stable at high temperature, long fire time | Good toughness |
Borosilicate 4.0 Excellent performance:
?×10-6 (20-300 ° C) thermal expansion coefficient, 2-3 times lower than ordinary glass (silicate glass), creating more than 3 hours of fire time
?851 ° C ultra high softening point for fire stability
? no NiS crystallization to eliminate self-explosion hazards
? fully toughened monolithic fireproof glass for double safety requirements
? 90% Very high light transmittance, low iron formula for true color rendering
? Excellent borosilicate optical quality for distortion-free visual effects
?2.28g/cm3(25°C) density, low weight to maintain a small figure
?'s super-high mechanical strength makes it lightweight and contains unlimited power
? Good corrosion resistance, stable and not afraid of UV light
