What Type of MgO is Suitable for Making Mgo Board?

MgO Board is a nice fireproof material that is widely used in buildings, no matter for walls, sub floorings, etc. You could have more information from previous article: https://www.dhirubhai.net/pulse/what-magnesium-oxidemgo-board-jason-wang/

Many customers are seeking to set up a production line in their country, but don’t know about the raw materials. The main raw material is MgO, magnesium oxide, which is a type of mineral cement, and contains magnesium (which has the chemical symbol of Mg) and oxygen (the chemical symbol of O).

So, let’s get through about the MgO.

What is the MgO Powder?

Magnesium oxide powder (MGO powder) is a white powdered mineral that is a source of magnesium. It is also called Magnesia or MgO.

Magnesium oxide powder is obtained from the extraction of magnesium carbonate (MgCO3), sometimes referred to as magnesite. Magnesite is calcined at temperatures greater than 600 °C to produce magnesium oxide. The calcination temperature and duration has a significant influence on the crystal size, particle surface area and degree of reactivity of the resultant magnesium oxide

What it performs like in making the MgO Board.

The MgO performs like a cement material in making the MgO board. There are two different formulas for making the MgO board, one is chloride(MgCl2), another one is sulfate(MgSO4). No matter which one, the MGO will combine and become a cementitious material, as the core part of the MgO board.

Magnesium oxychloride cement has been around for many years having been first reported by French scientist Stanislas Sorel in 1866. So sometimes you also heard it is Sorel cement/magnesia cement.

There are two main hydrate phases (magnesium chloride hydroxide hydrates) responsible for the hardening and strength of magnesium oxychloride cement, these are 5 Mg(OH)2·MgCl2·8H2O (5-phase) and 3 Mg(OH)2·MgCl2·8H2O (3-phase). Other phases of magnesium chloride hydroxide hydrate known as 2-phase and 9-phase can also be formed during the reaction process, but are not stable at ambient temperature.

What is the right MgO powder?

In fact, except for the use of making MgO board, the MgO powder could be widely used in different areas, such as food, and medicine. The MgO has different purity and different specifications, for making the MgO board generally us industry-grade powder.

There are mainly three key factors, the content of MgO (%), activity, and other impurities content. Below is a typical MgO powder used in the ZHUCHEN MgO board factory. Every batch of the MgO powder will has such test report. ?

If you would like to know if your MgO powder is suitable or not, you could contact some MgO board manufacture or the MgO board manufacturer (like Yurui Machinery, www.yuruimachine.com) to ask for some comments.

Except for the China suppliers, other countries also have sources, like the Baymag from Canada, some factories in Turkey, Brazil etc.

How to Storage the MgO Powder?

In China, when we source the MgO powders (ZHUCHEN MgO Board) generally packaged in big packages (directly called Ton bags in China)?

For overseas markets, when delivering to customers, the most popular type is 50KG smaller bags, easier to handle and deliver.

So here we would like to share some tips of storage for your reference.

During the storage of MgO powder, need to avoid moisture, and water, if touched with water will be damaged. If stored improperly, its active content will be reduced, affecting production, so in storage, one must take some actions to protect it.

1. Covered with plastic film, plastic film on the ground, this method can be used to prevent moisture.
2. inverting bags for packing and sealing for preservation.
3. Place lime block among the packages to prevent moisture, which is another way to prevent magnesium oxide from absorbing moisture and prevent the reduction of activity.
4. as calcium oxide has higher moisture absorption, placed in the warehouse calcium oxide, used as a moisture-reducing agent, to reduce the humidity of the warehouse, very effective.
5. the longer magnesium oxide is stored, the greater the amount of conversion into Mg(OH)2, and the lower the activity. So magnesium oxide should not be stored for too long.

During the production MgO board, for the raw materials, maybe you still have questions or concerns about it.?
