What Makes Up Magnesium Oxide Board

Knowing what magnesium oxide board is made of helps you understand its special features. Each part has a role in making it strong, fireproof, and eco-friendly. Let’s look at the main ingredients that create this useful board.

Magnesium Oxide

Magnesium oxide is the main part of the board. This natural mineral comes from magnesite and is heated to change its form. It can handle high heat, making it great for building materials. Studies show heating magnesium oxide makes it stronger. At 250°C, it becomes tougher than Ordinary Portland Cement (OPC). This happens because new crystal structures form during heating, as seen in detailed studies.

Magnesium oxide also helps the board resist fire. It doesn’t burn even in very high heat, which makes it good for fireproofing. It also resists moisture, so it stays stable in wet places.

Bonding Agents (Magnesium Chloride or Magnesium Sulfate)

Bonding agents like magnesium chloride or magnesium sulfate hold the board together. They react with magnesium oxide to form a strong cement. This reaction creates a solid base that keeps all parts connected.

The bonding agent used depends on what the board needs. Magnesium chloride makes the board better at resisting water. Magnesium sulfate makes it last longer in areas with lots of chloride. Both options keep the board strong over time.

Reinforcing Fibers

Reinforcing fibers make the board stronger and more flexible. These fibers, like wood, fiberglass, or synthetic materials, spread stress evenly. This stops cracks and helps the board handle heavy weight.

Fibers also make the board resist damage from impacts and wear. Boards with fibers are strong, with levels between 10 and 16 MPa. This makes them good for busy places like offices or public buildings.

Fibers also keep the board light. Even though it’s strong, it’s easy to carry and install. Its density is usually between 1000 and 1100 kg/m³.

Fillers (Perlite, Vermiculite, Wood Fibers, Fiberglass Mesh)

Fillers are important parts of magnesium oxide board. They make the board better by improving insulation, lowering weight, and adding strength. Let’s look at the common fillers used in making mgo board.

  • Perlite: Perlite is a light volcanic glass that expands with heat. It creates tiny air spaces in the board, helping it keep heat out or in. This makes the board energy-saving and good for places needing temperature control. Perlite also makes the board lighter, so it’s easier to carry and install.

  • Vermiculite: Vermiculite is another natural mineral used as a filler. Like perlite, it expands when heated. This helps the board resist fire better. Vermiculite also reduces noise, making magnesium oxide board great for quiet spaces.

  • Wood Fibers: Wood fibers make the board flexible and strong. They spread stress evenly, stopping cracks and damage. These fibers are eco-friendly since they often come from recycled wood. If you want a green building material, this is a great feature.

  • Fiberglass Mesh: Fiberglass mesh strengthens the board and protects it from impacts. It holds all parts together, making the board tough for busy areas. Fiberglass mesh also keeps moisture out, so the board stays stable in wet places.

Each filler has a job, helping the board work well. Together, they make a material that is light, strong, and useful. This mix of fillers makes mgo board a smart pick for modern building projects.

Tip: Think about how fillers improve the board when choosing one. This helps you pick the best board for your needs.

Purpose of Materials in MgO Board

Role of Magnesium Oxide in Strength and Fire Resistance

Magnesium oxide is key to making the board strong and fireproof. When heated, it changes into a tough and solid material. It can handle high heat without breaking, making it perfect for fireproofing. Tests like ASTM E119 and NFPA 285 show it stays strong during fires. These tests also prove it stops fire from spreading on walls.

Magnesium oxide keeps the board strong even in tough conditions. Aging tests show it stays durable after years of use. Other tests show it works well in different environments. Its strength and fireproofing make it a safe and reliable building material.

Function of Bonding Agents in Binding Components

Bonding agents, like magnesium chloride or magnesium sulfate, hold the board together. They mix with magnesium oxide to create a strong bond. Tests show how these agents improve the board’s strength. For example, pure MOC adhesive has a shear strength of 2.62 MPa. Adding 0.5% SHP boosts this to 2.81 MPa, a 24.89% increase. Wet strength also improves by 109.78% with SHP.

Combining MOC with SHP and SP0.4% makes it even stronger. This mix reaches dry and wet strengths of 3.43 MPa and 2.28 MPa. These are 52.44% and 147.83% better than untreated adhesives. Bonding agents not only hold parts together but also make the board last longer and perform better.

Contribution of Reinforcing Fibers to Durability

Reinforcing fibers make magnesium oxide boards tougher and more durable. These fibers, like wood or fiberglass, spread stress evenly. This stops cracks and helps the board carry heavy loads. Boards with fibers are strong, with levels between 10 and 16 MPa. This makes them great for busy places like offices.

Fibers also protect the board from impacts and wear. They absorb shocks and reduce damage risks. Even with these benefits, the board stays light, weighing 1000 to 1100 kg/m³. This makes it easy to carry and install while staying strong for tough jobs.

Note: Reinforcing fibers are safe and non-toxic. This makes the board good for homes and businesses. It also meets the need for eco-friendly building materials.

How Fillers Help with Lightweight and Insulation

Fillers are key to making magnesium oxide board work better. They help with insulation, make the board lighter, and improve its overall use. Knowing how fillers work shows why they are important for building materials.

Making the Board Lighter

Fillers like perlite and vermiculite make the board weigh less. Perlite is a volcanic glass that grows bigger when heated. This creates tiny air spaces inside the board. These spaces lower the board’s weight but keep it strong. A lighter board is easier to carry and install, especially for big projects. It also puts less strain on buildings, which is helpful for tall structures.

Vermiculite works in a similar way. It expands when heated, adding size without adding weight. This keeps the board strong but easy to move and use. Whether you’re a builder or doing a DIY project, the lighter board makes your job simpler.

Better Insulation

Fillers also make the board better at keeping heat in or out. For example, MagPanel MgO boards have an R-value of 0.20 to 0.40 per inch. This is much better than cement boards, which have an R-value of 0.05 to 0.20 per inch. A higher R-value means the board insulates better, saving energy and keeping rooms comfortable.

Perlite and vermiculite trap air in their structures. Air doesn’t let heat pass through easily, so these fillers help keep heat inside during winter and outside during summer. This makes magnesium oxide board a smart choice for energy-saving buildings.

Reducing Noise

Fillers like vermiculite also help block sound. Vermiculite’s expanded structure absorbs sound waves, cutting down noise through walls and ceilings. If you want a quiet space, like a home office or studio, this feature is very useful.

Many Uses and Benefits

The mix of lightweight and insulation features makes MgO boards useful in many ways. You can use them for walls, ceilings, or floors, knowing they will work well. Fillers not only improve the board but also make it eco-friendly by using natural or recycled materials.

Tip: Check the fillers in an MgO board before buying. This helps you pick the right board for your needs.

Properties of MgO Board
