Gypsum board face paper Physical index 100

After entering the 21st century, gypsum board began to enter the Chinese market rapidly, and because of its light material, fireproof, convenient construction and other characteristics, it is widely used in home decoration ceilings and partition walls. According to the analysis of Chen Shijie, a technical expert on gypsum board, the reason why gypsum board can be rapidly promoted and applied, and it has not been eliminated in the process of more than 100 years, is inseparable from its superior performance. The production of gypsum board has low energy consumption and high production efficiency

The energy consumption of producing the same unit of paper gypsum board is 78 % less than that of cement. Moreover.

With less investment, large production capacity, convenient for large-scale production, there are production lines with an annual production capacity of more than 40 million square meters abroad. In addition, it is lightweight, with paper gypsum board as a partition wall, the weight is only 1 15 of the same thickness of the brick wall, 1 10 of the block wall, which is conducive to the seismic resistance of the structure, and can effectively reduce the cost of the foundation and the main body of the structure.

In addition, gypsum board also has good thermal and sound insulation properties. Due to the porous structure of gypsum board, its thermal conductivity is 0 16w (m k), which has significant advantages over the thermal insulation performance of sand-lime brick blocks (1 1w (m k)), while its unique cavity structure greatly improves the sound insulation performance of the system. And, because the gypsum core itself is not combustible, and in the process of releasing the combined water when it encounters fire, it will absorb a lot of heat, delaying the rise of the surrounding environmental temperature, therefore, the gypsum board has good fire retardant performance, and the fire resistance limit of the gypsum board partition wall can reach 4 hours after being tested by the National Fire Prevention Testing Center.

The vast majority of calcium silicate boards and cement fiber boards are made of asbestos as the reinforcing material of the board, which has the characteristics of environmental protection, and because the gypsum board has a unique "breathing" performance, it can adjust the indoor humidity within a certain range to make the living comfortable.

Due to the relatively high quality of gypsum board, it is mainly used in hotels, restaurants, office buildings, public buildings, apartments and villas and other high-end buildings in large and medium-sized cities across the country. It is reported that the ordinary type of gypsum board per square meter is 50-60 yuan, and waterproof, fireproof and other special gypsum board per square meter is 100-200 yuan.

Manufacturers cut corners and affect the healthy development of the industry.

<> characteristics of gypsum board are mainly divided into seven parts: High production efficiency and low energy consumption: the energy consumption of gypsum board in the production of the same unit is 78% less than that of cement.

Lightweight: The user's paper-faced gypsum board is used as a partition wall, and the weight is only 1 15 of the same thickness of a brick wall. Thermal insulation:

About 60% of the gypsum board core is tiny pores, because the thermal conductivity of air is very small, so it has good light thermal insulation performance. Fire prevention: Because the gypsum core itself does not burn, and in the process of releasing chemical water when encountering fire, it will absorb a large amount of heat and delay the rise of the surrounding ambient temperature.

Sound insulation: The gypsum board partition wall has a unique cavity structure, which greatly improves the sound insulation performance of the system. Good decoration function:

The surface of the plaster bar is flat, and the seamless surface is formed by seam treatment between the boards, and the surface can be directly decorated. Convenient and good constructability: gypsum board has the properties of nailing, sawing, planing and sticking, and can be used for interior decoration to achieve ideal results.

In the production of the same unit of gypsum board, the energy consumption is 78% less than that of cement. And less production capacity, simple process, suitable for large-scale production.

The weight of the user's paper-faced gypsum board partition wall is only 1 15 of the same thickness of the brick wall and 1 10 of the block brick wallIt is conducive to the seismic resistance of the structure and can effectively reduce the main cost of the basic structure.

About 60% of the gypsum board core is tiny pores, because the thermal conductivity of air is very small, so it has good light thermal insulation performance.

Because the gypsum core itself will not burn, and in the process of releasing the combined water when encountering fire, it will absorb a large amount of heat and delay the rise of the surrounding ambient temperature, so the gypsum board has a good fireproof and flame retardant shape. In the results of the fire test, the limit of fire resistance of the gypsum board partition wall can be up to four hours.

The single-layer wall composed of a single lightweight material, such as aerated concrete, expanded perlite slab, etc., can only meet the sound insulation needs when its thickness is very large, and the gypsum board partition wall has a unique cavity structure, which greatly improves the sound insulation performance of the system.

The surface of the plaster bar is flat, and the seamless surface is formed by seam treatment between the boards, and the surface can be directly decorated.
