1, safety: mainly refers to its fire resistance is good.

This is mainly because dihydrate gypsum (CaSO4 · 2 h2o) contains two crystallization water, accounts for about 21% of the total. These two water of crystallization in the existence of the stable gypsum at ordinary times, in high temperature, the water can quickly spread to the wall surface in the air, on the wall, form a layer of water film on the surface of materials. The water film can reduce the surface temperature of the wall materials, can have the effect of isolating oxygen again, in order to prevent and delay the further combustion of wall materials and structures, so the water of crystallization in Germany is called "extinguishing water". Gypsum block according to the 66 kg/m2, which contains about 13.86 kg of "fire water", fireproof limit of more than three hours.

2, comfortable: refers to the "respiratory function" and "warm

"Respiratory function" means of gypsum block Have the ability to adjust indoor air humidity. The microporous structure of the plaster is composed of acicular crystal cross dihydrate gypsum, therefore in the needle crystal structure there are a lot of free space, namely high void fraction. When the air

In high humidity, gypsum can absorb moisture in the air by capillary structure, water storage rate can reach 7 to 17 g/m 2, than cement mortar (water storage rate of 69 g/m 2) can store nearly doubled over the water. Because the coefficient of water vapor diffusion resistance of gypsum is lower than cement mortar, when the bottom of the humidity in the air, the water in the gypsum wool stoma structure is easy to evaporate into the air, to adjust indoor air humidity, make the person feel comfortable.
