Fire-Resistant Properties of Magnesium Sulfate Boards
Material Composition and Characteristics
Magnesium sulfate boards are great for fire safety. They do not burn, making them very reliable. Boards like MagPanel are made with special materials. They use magnesium oxysulfate cement (MOSC), which forms crystals when mixed with water. These crystals make the boards strong and heat-resistant.
Key features of magnesium sulfate boards include:
They do not catch fire or spread flames.
Thicknesses from 2.5 to 10 inches, lasting over 3 hours in fire.
These qualities make them perfect for homes and buildings.
Mechanisms of Fire Resistance
Magnesium sulfate boards resist fire because of their chemical makeup. When exposed to fire, MOSC reacts with water. This reaction creates a new crystal phase called the 5·1·7 phase. This phase makes the boards stronger and better at handling heat.
Mechanism | Description |
|---|---|
Hydration Process | Water reaction forms crystals that improve fire resistance. |
Crystalline Phase | The 5·1·7 phase adds strength and water resistance for fire safety. |
Modifier Effects | Additives like PBTC and HPMA improve fire-resistant properties. |
These processes help the boards stay strong even in extreme heat. They perform better than many other materials.
