Frameless fireproof glass is composed of multi-layer glass original sheet and water-soluble inorganic fireproof glue interlayer, with fire resistance and heat insulation.

The fire prevention principle of the heat insulating frameless fireproof glass is that when a fire breaks out, the special transparent chemicals in the center of the heat insulating composite frameless fireproof glass absorb a large amount of heat in the flame and foam and swell, and become opaque white together, which can effectively prevent the heat of combustion from being transmitted from the fire facing to the fire facing back, It also suppresses the heat radiation of the flame on the fire facing surface of the glass from transmitting to the fire back surface. In this process, the glass is intact as a whole, forming a useful barrier that can block the laxity and extension of high-temperature toxic gas of flame, smoke and combustion.

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

In Europe, there is a strict definition of heat-insulating frameless fire-proof glass. It requires that the uniform heating temperature of the back fire surface shall not be higher than 140 ℃ within the requested fire-proof time, and the heating temperature at any point shall not be higher than 180 ℃.

In Europe, it is necessary for frameless fire-proof glass to systematically end fire prevention together with fire-proof structure, rather than just considering frameless fire-proof glass. At present, when talking about frameless fire-proof glass in China, the importance of structure is ignored. Assuming that the structure is not a fire-proof structure, when there is a fire, the structure has softened and deformed, no matter how good frameless fire-proof glass is. The structure must be closely connected with the glass, and the corresponding structural equipment accessories are also very important.
