Fire-resistant gypsum board faced by pink protective paper .Using high-purity natural gypsum powder as main material, mixed with fire resistant materials and fire resistant fibers to make board core. It is made up of specially treated and crystal water gypsum material, which determines that at the beginning period when it meets fire, before the crystal water in the board core fully comes out, the temperature at the board surface cannot exceed 140C. This good fire resistant property can obtain valuable time for people to evacuate. Meanwhile prolong the fireproof time. The paper-faced gypsum board release vapor when it is heated, so that it avoids the dangers of people suffocation because of breathing in poisonous gas from fire. Fireproof gypsum board is a new product based on the basis of traditional plasterboard innovation and development. It is not only have the plasterboard advantages of light weight, stable, artistic, sound-proof, heat retaining, quake-proof, crashworthy, but also add some additives in board core, strengthen the board performance in fire in certain long time. These additives can help the plasterboard keep complete structure (in architectural structures), thus plays the role of blocking flame spread, to obtain valuable time for people to escape.

2Feature Besides having baier standard plasterboard performance outside, such as, light, stable ,artistic, sound-proof, moisture-resistant, crashworthy, insulated, still have higher fire-proof performance, and the fireproof time is more than 60 minutes.

3 Fire prevention principle Fire prevention board theory mainly lies in the board core. 1. On the one hand, crystal water is one of the important reasons for the fireproof board. When It meets fire, before the free water in the board core fully comes out and vapors up, it absorb a small amount of heat, reduce the temperature around the board. When the temperature continues to rise, crystal water decomposed into gypsum and moisture, This process requires absorb a lot of heat, In a relatively long time, it will avoid temperature rising too fast. 2.On the other hand, in order to improve the plasterboard fireproof performance, add some additives in board core. mixed with fire resistant materials and fire resistant fibers .
