Key technology points of composite heat insulation fireproof glass

2020-02-27 1076

Composite heat insulation 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 thermal insulation fireproof glass is that in case of fire, the transparent chemical substances in the middle of thermal insulation composite fireproof glass absorb a large amount of heat in the flame and expand, and turn into opaque white together to hinder the heat generated by incineration

Conduct from the fire facing surface to the back fire surface, and together block the heat radiation of the glass fire facing surface flame from transmitting to the back fire surface. In this process, the glass is intact as a whole, forming a useful barrier that can block the dispersion and spread of high-temperature toxic gas caused by flame, smoke and incineration.

The function of heat insulation and heat radiation prevention of composite fire-proof glass can prevent the escape or rescue personnel in the area behind the fire surface of the glass from being damaged by high-temperature heat and burned by 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.

Composite heat insulation fireproof glass has a strict definition. It requires that the uniform heating temperature of the back fire surface shall not be higher than 140 ℃ within the required fire prevention time, and the heating temperature at any point shall not be higher than 180 ℃.
