Preferably, in a preferred technical solution of the present embodiment, wherein the block body 1 is made of gypsum. Specifically, the gypsum block is a light building gypsum product prepared by taking gypsum as a main raw material and adding water, stirring, casting, molding and drying. The gypsum product has the following characteristics:
1) safety: mainly means that it is fire resistant. This is mainly due to dihydrate gypsum (CaSO)4·2H2O) contains two crystal waters, about 21% by weight. The two crystal levels are stable in the gypsum at ordinary times, and when the gypsum is subjected to high temperature, the water can be rapidly diffused into the air on the surface of the wall body, so that a water-air film is formed on the surface of the wall body material. The water-gas film can reduce the surface temperature of wall material and reduce the temperature of wall materialThe crystal water plays a role of isolating oxygen so as to prevent and delay further burning of wall materials and buildings, so the crystal water is called 'fire extinguishing water' in Germany. 66kg/m of gypsum block2About 13.86kg of fire extinguishing water is contained, and the fire resistance limit reaches more than 3 hours;
2) comfort: refers to its "respiratory function" and "warmth". The breathing function means that the gypsum block has the function of adjusting the indoor air humidity. The microporous structure of gypsum consists of intersecting dihydrate gypsum needle crystals, so that a large amount of free space exists in the needle crystal structure, i.e. the porosity is high. When the humidity in the air is high, the gypsum can absorb the moisture in the air through the capillary structure, and the water storage rate can reach 7-17g/m2Cement mortar (water storage rate 6-9 g/m)2) Can store more than one time of water. Because the water vapor diffusion resistance coefficient of the gypsum is much lower than that of cement mortar, when the humidity in the air is low, water in the capillary pore structure of the gypsum is easy to evaporate into the air, so that the effect of adjusting the indoor air humidity is achieved, and people feel comfortable. 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 description is only for the 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 should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
