Gypsum board in the performance characteristics

Oct 17, 2017

Gypsum board is a natural gypsum and face paper as the main raw material, mixed with appropriate amount of fiber, starch, coagulant, foaming agent and water made of lightweight construction sheet. In performance there are the following characteristics:
Low energy efficient
Production of the same unit of paper gypsum board energy consumption than cement savings of 78%. And the investment less production capacity, simple process, easy to large-scale production.
Lightweight
With gypsum board for the wall, the weight is only the same thickness of the brick wall 1/15, block wall of the 1/10, is conducive to structural seismic, and can effectively reduce the basic and structural cost.
Thermal insulation
Gypsum board board core is about 60% of the tiny pores, because the air thermal conductivity is very small, so has a good light insulation performance.
Fire performance
As the gypsum core itself is not combustible, and the case of fire in the release of water during the process will absorb a lot of heat, delay the ambient temperature rise, so the paper gypsum board has a good fire and flame retardant properties. Inspection by the National Fire Detection Center, paper gypsum board partition fire resistance up to 4 hours.
Sound insulation performance
The use of a single lightweight material, such as aerated concrete, expanded perlite plate and other components of the single-wall thickness of its large to meet the requirements of sound insulation, and paper gypsum board partition has a unique cavity structure, Good sound insulation performance.
Decorative function
Gypsum board surface is flat, between the board and the board through the joint treatment to form a seamless surface, the surface can be directly decorated.
