Gypsum is a fireproof building material recommended by the state. It has superior fireproof performance and is a non-combustible A1 inorganic material.
Gypsum has a large amount of crystal water (about 21% by weight) after it is condensed. The crystal water can be released first under heated conditions. The formed water vapor can effectively prevent the flame from spreading. The dehydration process can absorb a lot of heat. Delay the time for the wall to heat up and control the degree of damage to the building from the fire.
