Chemical Composition of Magnesium Sulfate Board 517 Phase
Key Parts of Magnesium Sulfate Board
Magnesium sulfate board is made from special materials. The main part is magnesium sulfate, which forms the base. It is mixed with the 517 phase, a crystal structure that makes it better. The 517 phase dissolves very little in water, only 0.034 grams per 100 grams. This is much less than other phases like 3·1·8 and 5·1·8 in magnesium oxychloride cement.
The formula used in these boards gives them strength and durability. It also makes them resist water and heat well. These features make magnesium sulfate boards useful for many things. They are used in construction for both structure and decoration. You can also find them in products like plastering spray mortar and waterproof mortar, showing how flexible they are.
How the 517 Phase Forms and Works
The 517 phase is very important for magnesium sulfate boards. It forms when magnesium sulfate reacts with water and other materials. Adding about 5% crystal seeds helps create the 517 phase. This phase gives the board its strength and long-lasting quality.
The 517 phase also helps the board resist water and mold. Its low solubility keeps the board strong even in wet places. This makes it great for insulation and fire protection. The whisker-like shape of the 517 phase also improves the board’s strength, making it perfect for modern buildings.
How Chemical Makeup Affects Strength
The chemical makeup of magnesium sulfate board affects how strong it is. The 517 phase makes the board very strong, with a compressive strength of 21.5 MPa after 12 hours. This means it can hold heavy loads and stay stable. Boards with more 517 phase are also better at bending, especially when reinforced with glass fibers.
The table below shows how the chemical makeup affects the board:
Feature | What Happens |
---|---|
Compressive Strength | The 5-1-7 phase makes MOS-CA much stronger than MOS-0. |
Flexural Strength | More phase 5 means better bending strength in glass fiber boards. |
Main Hydration Product | The whisker 5·1·7 phase combines the best of MOC and MOS cement. |
These qualities make bmsc 517 magnesium sulfate board a top choice for building. Its chemical makeup ensures it lasts long, even in tough conditions. Whether for structure or insulation, this board works great.
Key Properties of Magnesium Sulfate Board
Fire Resistance and Safety Features
Magnesium sulfate board is great for fire safety. Its enhanced fire resistance makes it perfect for noncombustible applications. The basic magnesium sulfate cementitious formula helps it not catch fire easily. This gives passive fire protection, which is important for modern building projects.
The fire rated structural board can handle high heat without breaking. This makes it useful in places like kitchens, factories, and public spaces. It also stops flames from spreading, helping with better insulation during fires.
Waterproofing and Moisture Resistance
Magnesium sulfate board is excellent at keeping water out. Its waterproofing and moisture protection make it great for wet areas. The basic magnesium sulfate cementitious formula stops water from soaking in. This keeps the board strong even in damp places.
Adding materials like rice husk ash (RHS) improves water resistance even more. This makes the board work well in bathrooms, basements, and outdoor spaces. Its moisture protection ensures it lasts a long time.
Durability and Longevity
Magnesium sulfate board is very strong and long-lasting. Its impact resistance performance helps it handle heavy use. The flexural strength, especially with glass fibers, stops it from cracking when bent.

Comparison with Other Materials

Magnesium Sulfate Board vs. Magnesium Oxide Board
Magnesium sulfate board and magnesium oxide board are different in many ways. Magnesium sulfate board uses magnesium sulfate to hold it together. Magnesium oxide board, however, uses magnesium chloride as its binder. This difference changes how they handle water and last over time. Magnesium sulfate board doesn’t soak up much water, so it works well in wet places. Magnesium oxide board absorbs more water, which can make it weaker after a while.
They also differ in fire resistance. Magnesium sulfate board can resist fire for 1 to 4 hours, depending on thickness. Magnesium oxide board has an A1 fire rating, meaning it won’t burn. Both are good for fire-safe buildings, but magnesium sulfate board is better for damp areas.
Feature | Magnesium Sulfate Board | Magnesium Oxide Board |
---|---|---|
Binding Agent | Magnesium sulfate | Magnesium chloride |
Fire Resistance | 1 to 4 hours (varies by thickness) | A1 fire rating (non-combustible) |
Water Resistance | Low absorption, suitable for damp areas | Higher absorption, can weaken over time |
Performance and Durability Differences
Magnesium sulfate board is stronger and lasts longer than magnesium oxide board. It doesn’t absorb much water, so it stays strong in wet places. The 517 phase in it makes it tough and stops it from bending or cracking. This makes it great for busy areas and big projects.
Magnesium oxide board is strong too, but it doesn’t do well in wet conditions. It works better in dry places but isn’t as flexible as magnesium sulfate board. If you need a material that’s strong, water-resistant, and fire-safe, magnesium sulfate board is the best pick.
Environmental Impact Comparison
Magnesium sulfate board is better for the environment than magnesium oxide board. It takes less energy to make, which lowers carbon emissions. Unlike magnesium oxide board, it doesn’t need high-heat kilns that use a lot of power. This makes magnesium sulfate board a greener choice for building.
Magnesium sulfate board also creates less waste when installed. Its exact size means fewer scraps, and it can be recycled easily. Magnesium oxide board can also be recycled but makes more waste because it absorbs more water and can get damaged. Choosing magnesium sulfate board helps the planet and supports eco-friendly building.
