Sulfur oxygen adding calcium sulphate magnesium fire prevention board is in magnesium chloride solution or a mixture of calcium sulfate and calcium phosphate. Widely used in magnesium fire door core board, exterior wall insulation board, siliceous modification board, fire prevention board, and many other fields.
Sulfur oxide magnesium fire board performance characteristics:
1, gas hard
Sulfur oxide magnesium board is different from ordinary Portland cement condensation curing mechanism, it is a rigid gelled material gas, no hardening in the water.
2, multicomponent
Sulfur oxide magnesium board is a multi-component, one component of the light burning powder and water little strength after hardening. It is the main component light burning powder and magnesium sulfate, other components, including water, modifier and filler, etc.
3, no corrosion of mild steel
Sulfur oxide magnesium plate with magnesium sulfate as a harmonic agent, compared with magnesium oxychloride is fire prevention board do not contain chlorine ion, on steel corrosion, so the sulfur oxide magnesium board can take the place of magnesium oxychloride cement used in fire door core board and external wall insulation board area, reduce the risk caused by chloride ion erosion of steel.
4, high strength
Sulfur oxide magnesium board add modification can reach 60 mpa compressive strength, flexural strength can be up to 9 mpa.
5, air stability and resistance to weathering
Sulfur is rigid gelled material gas, oxygen magnesium board only hardened to continue condensation in the air, which makes it has a good stability of the air. Sulfur oxide magnesium board after curing, the environment in the air is dry, it becomes more stable. Test shows that sulfur oxide magnesium fire board products in dry air, the compressive and bending degree increase with age, until the two ages is growing, is very stable.
