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

The fire prevention principle of heat insulation fireproof glass is that when a fire breaks out, the particularly transparent chemical substances in the middle of the heat insulation composite fireproof glass absorb a large amount of heat in the flame and foam and expand, and become opaque white together, which effectively prevents the heat generated by combustion from being transmitted from the fire facing surface to the back fire surface, and prevents the heat radiation of the flame on the fire facing surface of the glass from being transmitted to the back fire surface. In this process, the glass remains intact as a whole, forming an effective barrier that can block the diffusion and spread of high-temperature toxic gas generated by flame, smoke and combustion.

The heat insulation and heat radiation protection functions of composite fire-proof glass can protect the escape or rescue personnel in the area behind the fire surface of the glass from the invasion of high-temperature heat and the burn of heat radiation, and prevent the combustible materials and articles in the area, such as wood products and carpets, from being ignited by high-temperature and heat radiation within a certain period of time.

There is a strict definition of composite heat insulation fireproof glass, which requires that the average temperature rise of the back fire surface shall not be higher than 140 ℃ within the required fire prevention time, and the temperature rise at any point shall not be higher than 180 ℃.

In, it is necessary for fire-proof glass to complete fire prevention systematically with fire-proof frame, rather than just considering fire-proof glass. At present, when talking about fire-proof glass in China, the importance of frame is basically ignored. If the frame is not a fire-proof frame, when a fire breaks out, the frame has softened and deformed, no matter how good fire-proof glass is. It is necessary for the frame to be closely connected with the glass, and the corresponding frame installation accessories are also very important
