The microporous structure of the gypsum is formed by crossing dihydrate gypsum needle crystals, so a large amount of free space exists in the needle crystal structure, namely the porosity is high; by "warm" is meant that the gypsum block has a large water-paste ratio, and a large amount of free water is evaporated after hydration hardening, leaving a large number of voids in the product. According to the difference of the volume density, the heat conductivity coefficient is 0.2-0.28W/m.K, which is similar to the average heat conductivity coefficient of wood; when the wall is used as a wall, the hand feeling is warm, and the wall is called as a warm material compared with building materials such as reinforced concrete and the like; the method is an important reason for selecting gypsum building materials indoors in many countries;
3) And (3) fast: the gypsum block has high construction speed and high efficiency;
4) and (3) environmental protection: the gypsum block has no environmental pollution in raw material, production, construction, use and waste recovery.
The above is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
