How is ETFE inflatableMebrane fireproof? Membrane structures not only have characteristics such as self-cleaning, anti-corrosion, and large span, but also have strong fire resistance characteristics. This article will introduce the principle of membrane structure fire prevention for everyone, so that you can have an understanding of it. Let’s follow the editor of Yixing Membrane Structure Company to take a look together.

Expandable fireproof coatings can only produce an expansion layer under high temperature flames under the action of foaming agents. The foaming agent decomposes upon fire and releases non combustible gases such as ammonia, water, carbon dioxide, and hydrogen halide, causing the coating to foam and expand upon reaching the softening point, forming a sponge like structure. After a fire occurs, the ETFE inflatable film will self melt and create voids, which are conducive to the discharge of smoke and heat, ensuring safety.

A catalyst is a substance that can decompose into phosphoric acid under certain conditions. The decomposed acid dehydrates polyols, forming a non flammable three-dimensional carbonization layer. Usually, the water solubility of melamine phosphate is smaller than that of polyphosphate amine, and it has both catalytic and foaming effects. Currently, melamine phosphate is mainly used as the catalyst.
