High Borosilicate fireproof Resistant Glass

High borosilicate fireproof glass now has widely been used in public buildings, industrial and residential buildings, commercial buildings, and other areas that require high fireproof performance.

There’re several kinds of single-piece fireproof glass, including cesium potassium fireproof glass, high compression stress glass, and high borosilicate fireproof glass.

According to the fire resistance time:

The fire resistance time limit is 0.5h, it is recommended to use cesium potassium fireproof glass and high-stress fireproof glass.

The fire resistance time limit is 1.0h, it is recommended to use high-stress fireproof glass.

The fire resistance time limit is 1.0h and more than 2.0h, and the size is larger than 3 meters. It is recommended to use high borosilicate fireproof glass.

Single piece cesium potassium fireproof glass

Factories will spray the fireproof liquids on the glass surface and through the physical tempering process, the cesium potassium fireproof glass performance can reach 30-60mins.

But as the factories’ processing capability and technology are different, most cesium potassium fireproof glass cannot perform its fireproof performance.

High compression stress fireproof glass
It’s the same as normal tempered glass but during the tempering process, factories will adjust the tempering parameter and make the glass with high compression stress.

The disadvantage of this kind of glass is glass cannot be made very big, and it’s not stable.

High borosilicate fireproof glass
It is the newest and most stable fireproof glass, it’s decided by the borosilicate glass characters.

High borosilicate fire-resistant glass contains high borosilicate, boron accounts for 12.5-13.5%, and silicon content is 78-80%.

This results in high borosilicate fire-resistant glass with superacid and alkali resistance and can adapt to a temperature difference of 520℃.

It can be kept at 750℃ for a long time without any change, and the softening point can reach above 850℃.

The advantage of high borosilicate fire-resistant glass are:

1. Excellent fire resistance
The ultra-high softening point provides a fundamental guarantee for the fire performance stably, and the fire resistance time exceeds 120 minutes.

With ultra-high transparency, while maintaining the transparency and beauty of the building,

It can still insure people’s vision in the event of a fire to facilitate escape and rescue.

2. High-strength and ultra-light performance

The weight is more than 8% lighter than ordinary glass, and at the same time, it has ultra-high mechanical strength.

The extremely strong and light characteristics significantly reduce the weight of the building.

3. Excellent optical performance

Low iron, environmentally friendly formula, high light transmittance, the visible light transmittance of 92%, excellent optical quality provides distortion-free visual effects.

4. Super high chemical stability

Acid resistance, alkali resistance, UV resistance, and good fire resistance.

5. No risk of self-destruction
Self-explosion is currently a major hidden danger that is extremely difficult to overcome for building safety glass.

Because the raw materials and systems of high borosilicate fire-resistant glass do not contain nickel.

There is no nickel sulfide crystal in all glass products, which eliminates the hidden danger of self-explosion.

6. Processability

It can perform a series of operations such as cutting, edging grinding, drilling holes, ceramic printing, coating, tempering, laminating, and insulating glass process.

High borosilicate glass can be combined with other glass to be made into a building energy-saving fire-proof material with better comprehensive performance through the processes of laminating, hollowing, and vacuum.

7. Double security
Fully toughened monolithic high borosilicate fireproof glass, meeting the requirements of fireproof and safety performance.
