What are the advantages and disadvantages of gypsum block?

Gypsum block can be a very light and dense material type, and the raw material of this gypsum block also contains fiber reinforced materials. The functions of gypsum blocks manufactured in this way become very extensive. For example, the sound insulation effect is good. Not only that, it is also very convenient to use this gypsum block in construction. In terms of fire prevention, this gypsum block is very low-carbon and environmentally friendly. Even if there is a smell, there is no harm. Once became the new wall of modern society!

The final hydration product of gypsum block is calcium sulfate dihydrate. In case of fire, only after the two kinds of crystal water are completely decomposed, a large number of water vapor curtains produced in the process of decomposition still play a role in preventing the flame from spreading. Comfort refers to the function of keeping warm and breathing, and the thermal conductivity of gypsum block is 0.20-0.28? W/m.K is close to the average thermal conductivity of wood. When the thermal conductivity of a material is small, its heat transfer speed is slow, on the contrary, its heat transfer speed is fast. High thermal conductivity. Fast refers to the fast production speed and high construction efficiency of gypsum building materials. Generally, the initial and final setting time of building gypsum is 6-30 minutes, which is faster than that of cement products.

Use:

1. Gypsum blocks are mainly used for non-bearing walls of frame structures and other structural buildings, and are generally used as internal partitions. Gypsum block adopts proper fixing and supporting structure, and the wall can also bear large load. Moisture-proof blocks mixed with special additives can be used in bathrooms, toilets and other places with high air humidity.

2. It is energy-saving, material-saving, recyclable, sanitary and does not pollute the environment.

3. Because of the water vapor diffusion of gypsum? Resist? Coefficient is much lower than that of cement mortar. When the humidity in the air is low, the moisture in the gypsum capillary structure easily evaporates into the air to adjust the indoor air humidity. It makes people feel very comfortable.

4. The water vapor permeability of gypsum block and? The PH value is strikingly similar to the chemical and physical properties of human skin, and it is called "skin-friendly" building material. Gypsum is also a good cosmetic mask material.

5. In the Pharmacopoeia of Western Medicine, pure gypsum is used as the drug base. In Chinese medicine, it is a good medicine for clearing fire blindly. It is recorded in Shennong Materia Medica and Kaibao Materia Medica that gypsum is pungent, sweet and cold, belonging to lung and stomach meridians. It can nourish yin, clear away heat, quench thirst, promote fluid production, promote blood circulation, relieve pain, and promote granulation. Therefore, it will make people feel very comfortable in the building built of gypsum building materials.

We can find two structural features of gypsum block, one is hollow and the other is solid gypsum block. However, the sources of gypsum blocks can also be divided into two types, one is natural gypsum blocks, and the other is manufactured chemical blocks. Both ordinary gypsum blocks and moisture-proof gypsum blocks can be classified according to the manufacturing method of molding-the molding of manual blocks and machine-made manual blocks is different.
