Precautions for fireproof glass door

1. Monolithic fireproof glass is a kind of fireproof glass with single-layer glass structure. Within a certain period of time, it maintains the integrity of fire resistance and blocks the open fire and toxic and harmful gases on the fire facing surface, but it does not have the effect of temperature insulation. When a fire occurs, a large temperature difference will be formed between the fire facing surface and the fire back surface of ordinary glass. Under the action of such temperature difference, a strong uneven thermal stress will be generated in 1 or 2 minutes, resulting in glass breakage. Even the glass after physical tempering will be completely broken in 3 or 5 minutes.

2. Monolithic fireproof glass has the characteristics of low thermal expansion rate after more than 20 hours of high-temperature ion exchange chemical treatment. The glass softens without breaking at high temperature, which can maintain the integrity, thus forming a safety barrier to prevent the diffusion and spread of flame and toxic and harmful gases.

3. Composite heat insulation fireproof glass is composed of multilayer glass original sheet and water-soluble inorganic fireproof glue interlayer, which meets the requirements of fire resistance integrity and fire resistance and heat insulation.
