Magnesium Oxide Board: A High-performance Building Material

Magnesium oxide board, also known as lightweight partition board, fireproof board, moisture-proof board, is a new type of building material made mainly from magnesium oxide. It is widely used in the field of architecture due to its outstanding performance.

Magnesium oxide board has a density only half that of ordinary concrete, is lightweight, and easy to transport and install. At the same time, it has high compressive and flexural strength, and after special processing, the main component magnesium oxide endows it with the characteristic of not easily deforming. It is also an excellent fire-resistant material, which does not ignite when exposed to fire and automatically expands to form a protective film when exposed to high temperatures, effectively preventing the spread of fire. Its fire rating can reach Class A. In terms of moisture resistance, magnesium oxide board also performs outstandingly, even in humid environments, it can maintain dryness and prevent problems such as wall mold and peeling. Its excellent sound insulation performance can effectively reduce noise transmission and create a quiet and comfortable indoor environment. The insulation performance is also worth mentioning, which can reduce heat loss and increase indoor temperature. Moreover, the production process does not produce harmful substances, meets environmental protection requirements, and is harmless to human health.

The application scenarios of magnesium oxide board are rich and diverse. In indoor wall decoration, it is suitable for spaces such as kitchens, bathrooms, bedrooms, etc. Its lightweight, fire-resistant, and moisture-proof characteristics make it an ideal choice. Magnesium oxide board is used for ceiling decoration, which is beautiful and practical. It can also be used for surface treatment such as spraying and veneering to enhance the decorative effect. As a flooring material, it has good sound insulation and thermal insulation properties, a smooth surface, and is easy to clean and maintain. In the field of furniture manufacturing, such as wardrobes, bookcases, etc., due to their lightweight and high strength, furniture has a good service life and stability.

However, magnesium oxide board also has some minor drawbacks. If the free chloride ions are not properly controlled, the water resistance may be poor and warping deformation may occur. When using reinforced concrete structures, if the content of magnesite cement exceeds 0.06%, it will have a certain degree of corrosiveness to the steel. But overall, magnesium oxide board has significant advantages and is a building material worth paying attention to and using.
