What Is the MgO Board Made Of?

10 Jul What Is the MgO Board Made Of?

MgO boards are made of Magnesium oxide and Magnesium chloride or magnesium sulfate(MgSO4) along with Perlite and additives. These substituents give MgO boards strength, durability, and make them a top building material.

This blog will delve into the composition and manufacturing process of MgO boards. So, let’s get into the topic.

MgO Boards- In a Nutshell 

MgO boards, the name we hear more often, are sleek and durable building materials. They are fiberglass, which is becoming a popular substitute for Portland cement. 

Both interior and exterior building construction use sheathing boards, such as MgO boards.

Unlike traditional gypsum boards, MgO boards are impervious to moisture damage. This makes them ideal for areas with high relative humidity or wetness. They are also environmentally friendly and support sustainable building methods.

MgO boards are renowned for their outstanding mold and fire resistance ability. 

Composition of MgO boards

MgO boards are made of diverse materials, which sets them apart from other boards. 

Here is the composition of MgO boards: 

1. Magnesium Oxide(MgO) 

Magnesium oxide is the most important thing when it comes to MgO boards. This core component is then combined with other materials to enhance functionality. This core material is derived from magnesite. It’s a naturally occurring mineral found in oceans. Magnesium oxide gives the board fundamental properties like fire resistance and strength. 

2. Magnesium Chloride 

As a strong binder, magnesium chloride helps bond the various ingredients together. This forms a solid, durable bond. It is usually mixed with magnesium oxide. 

3. Fibers and Fillers 

These usually include wood, glass, and synthetic fibers. These fillers and fibers enhance the board’s structural integrity, flexibility, and strength. 

4. Perlite, Vermiculite, and Other Aggregates 

These aggregates help to increase the insulation power of MgO boards. Besides this, they provide strength and stability. 

5. Water and Additives 

Water is essential for chemical reactions during manufacturing processes. It helps form solid and durable end products. Depending on the desired properties, additives can enhance these characteristics.

That’s all for the composition of MgO boards. Let’s head towards the manufacturing process. 

Manufacturing Process

The manufacturing process of MgO boards is more complex than it seems. It usually involves several steps to ensure high-quality products. Here are the steps that are followed during its manufacturing procedure: 

1. Mixing 

First thing first, mix all the raw materials and additives. Add water to form a homogenous mixture or slurry.  

2. Molding 

The slurry is then poured into molds of desired shape and thickness. The molds are designed to ensure uniformity and consistency across all the boards. This molding process is very complex as it involves handling intricate materials. 

3. Pressing 

After molding, the materials in the molds are pressed to remove any water. Pressing compacts the mixture, and it is crucial for various reasons; 

• To achieve the desired strength and density
• Make the boards more robust and durable. 

4. Curing 

After that, the pressed boards are left to cure. Depending on the manufacturing method, curing might happen in a controlled environment. However, curing can also be done at natural temperature. Allowing the chemical reactions to finish will produce a long-lasting board.

5. Finishing

The last step is very crucial. Once cured, the boards are sanded and trimmed to create smooth edges and surfaces. They then undergo a quality inspection before being packaged and sent. This process is critical to giving the boards a definite shape. It also helps give a refined edge and strengthen them. 

Fundamental Properties of MgO Boards

MgO boards offer a range of fundamental properties and benefits in construction. Here are some of them:

1. Fire Resistance 

Construction always starts with MgO boards because of their exceptional fire resistance. Suitable for fire-rated assemblies, these boards can tolerate high temperatures without catching fire.

2. Moisture and Mold Resistance 

Due to their moisture resistance, mold, and mildew cannot develop on MgO boards. As such, they are suitable for use in damp or humid areas. For example, outside sheathing, basements, and bathrooms.

3. Durability and Strength 

These boards withstand a great deal of physical wear and tear. Due to their excellent impact strength, you can apply heavy loads. And to our surprise, these boards won’t break or deform. 

4. Thermal and Sound Insulation 

The effective thermal insulation that MgO boards offer enhances energy efficiency. These boards won’t allow heat to pass quickly. This helps in maintaining constant interior temperatures. However, MgO boards are also helpful in sound insulation. These boards lessen sound transmission between rooms.  

5. Eco Friendly 

Because MgO boards have a cleaner life cycle. The manufacturing process does not release emissions. And the process is energy-efficient, too. Besides this, the material is recyclable making it an eco-friendly choice. 

Applications of MgO Boards

Due to their versatility, MgO boards can be used on a large scale.  Here are a few of them: 

1. Residential Construction

MgO boards can be used in residential buildings. They are widely used in toilets, bathrooms, rooms, and other corners of houses. 

2. Commercial and Industry Buildings

MgO boards are used for outside facades in commercial buildings. Business offices can also use them for ceiling tiles and office partitions. This will make a perfect soundproof meeting room. Their resilience to fire and longevity are especially useful in heavy-traffic areas. Besides this, buildings with strict fire safety regulations opt for them.

3. For Renovation

The easy installation makes them a quick pick for renovation. They can be applied on existing surfaces for: 

• Fire safety
• Moisture resistance
• Mould resistance 
• Insulation

Specialized Applications

Lastly, MgO boards are also used in specialized use cases such as:

• Fireproofing panels
• Hurricane sheathings
• Soundproofing barriers

After reading about all these properties, we can say it is a universal building material. MgO boards are perfect for use in public buildings.
