Glass magnesium board has good fire performance, is non-combustible board. Flame burning time is zero, no combustion at 800℃, no flame at 1200℃. When reaching the highest fire non-combustible grade A1, the partition system is made with high quality keel. When the fire resistance limit reaches more than 3 hours, in the process of fire combustion can absorb a lot of heat energy, delay the rise of ambient temperature.Properties
In dry, cold and wet weather, glass magnesium board performance is consistent. It is not affected by condensation water and humid air, even if it is soaked in water for several days and then dried naturally, it will not become deformed and soft. It can be used normally, there will never be moisture absorption halogen phenomenon. After testing, the board body has no water permeability.
The apparent density of glass magnesium plate is 0.8-1.2g/cm3, which reduces the building load. The weight of the interior wall of the building was reduced by more than 60% while the usable area was increased by 5-8%. Light weight is conducive to seismic resistance of the structure, effectively reducing the cost of foundation and structure.
Magnesite special 5.1.8 phase dense glass fiber cloth and good tenacity of plant fiber. Is glass magnesium board weight is light, but the structure is close, good stability, no deformation, with wood-like toughness. It has excellent performance in impact resistance, compression resistance, tensile resistance and fracture resistance. The bending strength reaches 322kGF /cm2 (vertical) and 216kGF /cm2 (horizontal), and the impact strength can reach 25MPa.
Glass magnesium plate does not contain asbestos, formaldehyde, benzene and harmful radioactive elements, smokeless, non-toxic, no smell. The production materials are natural mineral powder and plant fiber, and the production process is natural conservation. Less energy consumption, no sewage, energy saving and environmental protection, the use of the board does not contain powder. Its unique natural pore structure can adjust the indoor temperature, making the living room and office more comfortable.
Glass magnesium plate has the characteristics of uniform fine pores, dense and inorganic materials, and the thermal conductivity is 0.216 W /cm• K. It is more insulated than the 1.1W /cm•k of gray sand masonry. Can also save energy consumption, so that the room to maintain a comfortable environment, fresh air.
