Understanding Magnesium Oxide Boards

What Are Magnesium Oxide Boards?

Magnesium oxide boards are strong and useful building materials. They are made from magnesium oxide, a mineral found in nature. Manufacturers mix this mineral with other materials and add fibers for strength. The result is a lightweight and tough board. These boards work well in many building projects.

Here’s a simple look at their main features:

These features make them a smart choice for today’s buildings.

What Makes Magnesium Oxide Boards Special?

You might wonder why these boards are better than others. Their special qualities come from how they are made. Unlike plywood, which bends or swells when wet, these boards stay strong and keep their shape. They also handle fire better than gypsum boards, lasting up to three hours in flames.

Another great thing is they are eco-friendly. They are made from safe, natural materials and don’t harm the environment. They also stop termites, mold, and bacteria, which is helpful in damp or bug-prone areas. Plus, they block noise, making homes quieter and more peaceful.

Choosing magnesium oxide boards means picking a material that is strong, safe, and good for the planet. They meet global standards and perform better than many other materials, making them a big deal in construction today.

Scientific Composition of Magnesium Oxide Boards

Main Materials: Magnesium Oxide and Other Additives

Magnesium oxide boards, also called MgO boards, are made from special materials. The main ingredient is magnesium oxide (MgO), a natural mineral. This mineral is turned into a fine powder to form the board’s base. To make it better, manufacturers add materials like magnesium chloride, perlite, and fiberglass mesh.

Each added material has a job to do. Magnesium chloride helps hold the board together under pressure. Perlite, a light volcanic glass, makes the board weigh less and keeps heat out. Fiberglass mesh strengthens the board, stopping cracks and bends. These materials work together to make the board strong, long-lasting, and useful.

Why does this mix work so well? The answer is in the way magnesium oxide reacts with the additives. Together, they create a solid structure that resists water, fire, and pests. This makes sure MgO boards stay strong and useful, even in tough conditions.

Chemical Properties and Reactions

The chemical makeup of MgO boards makes them different from other materials. During production, magnesium oxide reacts with water to form magnesium hydroxide (Mg(OH)₂). This process, called hydration, makes the board strong and durable. Later, magnesium hydroxide reacts with carbon dioxide in the air to form magnesium carbonate (MgCO₃). This step, called carbonation, makes the board even more stable and tough.

Scientists have studied these reactions to understand MgO boards better. They used tools like X-ray diffraction (XRD) and thermo-gravimetric analysis (TGA). These studies showed that after 30 minutes of hydration, over 60% of the material turned into magnesium hydroxide. After 20 hours, this increased to over 70%. These results prove how quickly and effectively MgO boards change during production.

These reactions also help MgO boards resist fire. When heated, magnesium hydroxide releases water vapor. This cools the surface and slows down flames. This makes MgO boards great for fireproof buildings.

MgO boards also resist water damage. Unlike other materials, they don’t swell or break when wet. Their chemical makeup stops water from soaking in, keeping them strong in damp places. These chemical features show why MgO boards are a smart and modern choice for building projects.

Performance Characteristics of Magnesium Oxide Boards

Fire Resistance and Safety

Magnesium oxide boards are great at resisting fire. They can handle very high heat, making them safe for fireproof buildings. Tests show they resist fire for 2-3 hours at 800ºC. Some boards, like Magpanel, stay strong even after 30 minutes at over 750°C (1,382°F). They don’t even change color during this time.

These boards also have a 0/0 rating on the ASTM E84 / UL 723 test. This means they don’t spread flames or make harmful smoke. This makes them perfect for places like schools, hospitals, and homes where fire safety matters most.

Tip: Adding magnesium oxide boards to your building can improve fire safety. They help meet strict building rules and keep people safe.

Water Resistance and Durability

Magnesium oxide boards are strong against water and last a long time. Unlike other materials, they don’t swell, bend, or crack when wet. Studies show they stay solid even after being in water for a long time. This makes them great for bathrooms, kitchens, and basements.

These boards also stay durable over time. While their surface may age a little, their core stays strong. They work well in all kinds of weather, from hot to cold. They resist humidity and temperature changes, making them useful in many climates.

• Magnesium oxide panels survive harsh weather without damage.

• They don’t crack, bend, or swell, staying reliable for years.

• Their water resistance makes them perfect for damp areas.

Choosing magnesium oxide boards means your buildings will last longer, even in tough conditions.

Thermal Insulation and Energy Efficiency

Magnesium oxide boards help keep buildings warm in winter and cool in summer. They have high R-values, which measure how well they block heat. This reduces the need for heating and cooling systems, saving energy and money.

MgO structural insulated panels (SIPs) are especially good at stopping heat transfer. They make buildings more energy-efficient and eco-friendly. Using these boards can lower your carbon footprint and help the planet.

Note: Using magnesium oxide boards can save energy and cut utility costs over time.

Acoustic Performance and Soundproofing

Magnesium oxide boards (MgO boards) are tough and block noise well. They help make spaces quieter and more peaceful. Their special design stops sound from traveling through walls, floors, or ceilings. This makes them useful for homes and workplaces.

How Do MgO Boards Improve Acoustic Performance?

The boards are dense and solid, which reduces noise. They are made from magnesium oxide, minerals, bonders, and fiber mesh. These materials create a heavy board that absorbs sound waves. When sound hits the board, it stops vibrations and blocks noise.

For example, pairing a 13mm MgO board with 3mm mass-loaded vinyl improves soundproofing. This setup works well in places like offices, apartments, and studios where quiet is important.

Key Features Supporting Soundproofing

Here’s why MgO boards are great for blocking noise:

Thicker boards or adding sound-dampening layers, like vinyl, improve soundproofing. This makes MgO boards a smart choice for quiet spaces.

Why Choose MgO Boards for Soundproofing?

MgO boards work better than drywall or plywood for blocking sound. They are lightweight but still strong. They don’t have harmful chemicals, so they’re safe indoors. Plus, they resist fire, making them safer for buildings needing both soundproofing and fire protection.

Tip: Use MgO boards for home theaters, offices, or apartments. They block noise and meet safety rules, creating a better living or working space.

Choosing magnesium oxide boards gives you quieter rooms and safer buildings. They also help keep the environment healthy.
