Product characteristicsFireproof gypsum board is based on the traditional paper gypsum board on the basis of innovation and development of a new product, not only has the paper gypsum board of sound insulation, heat insulation, heat preservation, light weight, high strength, small shrinkage and other characteristics

The fire prevention principle of gypsum board lies in the core of gypsum board

One: CaSO4.2H2O, do not underestimate the two crystal water oh, gypsum board crystal water is an important reason for its fire protection。When the gypsum board is subjected to fire, the free water in the core of the board first evaporates out, absorbing a small amount of heat and reducing the temperature around the board。When the temperature continues to rise, the crystal water of the dihydrate gypsum begins to detach and decompose into gypsum and water, which requires the absorption of a lot of heat and can affect the temperature rise around the board for a relatively long time。

Second: the main reason for the fire failure of gypsum board is that the dihydrate gypsum shrinks and loses its integrity after removing the crystal water. In order to improve the fire resistance of gypsum board, some additives must be added to the gypsum board core。In addition to the fire expansion of refractory materials and a large number of refractory glass fibers, so that the overall volume can be ensured while the gypsum shrinkage, and the gypsum core material is pulled together without losing integrity。
