Magnesium sulfate board is also known as MGSO4 board, sulfate mgo board or chloride free mgo board. It is a light weight and waterproof non-asbestos and non-flammable panel product which is widely used in construction, decoration and SIPs (Structural Insulated Panels).
1. Mild and non-corrosive to steel
It uses magnesium sulfate as a blending agent. Compared with magnesium oxychloride cement, it does not contain chloride ions and is non-corrosive to steel. Therefore, magnesium sulfate board has replaced magnesium oxychloride cement in the field of fireproof door core board and exterior wall insulation board. Reduce the risk of corrosion of steel due to chloride ions.
2. High strength
After scientific modification of magnesium sulfate plate, the compressive strength can reach 60MPa, and the flexural strength can reach 9MPa.
3. Air stability and weather resistance
The magnesium sulphate plate is a gas-hardening cementitious material that can only continue to solidify and harden in air, which gives it good air stability. The more dry the air in the environment after curing, the more stable it will be. Tests have shown that the pressure and resistance of magnesium sulfate plates in dry air increase with age, until the two ages are still growing, very stable.
