Gypsum board about fire resistance knowledge

☆ Gypsum board why has good fire resistance performance?

Gypsum Board of the core material from the building gypsum hydration, so gypsum board gypsum is CaSO4 2H2O crystalline form exists. In the event of a fire, the gypsum board's gypsum will absorb heat for dehydration. When the crystalline water contained in the gypsum core material is not completely ejected and evaporated, the surface temperature of the gypsum board will not exceed 140 ℃, this good fire-proof characteristic can win the valuable time for the evacuation and prolong the fire time. Compared with other materials, gypsum board in the fire when the release of water and into water vapor, will not release harmful ingredients, and some other materials in case of fire, often dispersed to the human body harmful ingredients, such as poisonous smoke.


Gypsum board system is composed of gypsum board, light steel keel and various auxiliary materials. The type of gypsum board used,

Gypsum board Quality,

Gypsum board layer, keel quality and installation method, whether to fill the rock wool and rock wool bulk weight, joint treatment methods, some details of the node
