How Is The Fire Resistance of Magnesium Oxide Board Ensured

The fire resistance of magnesium oxide board can be guaranteed mainly due to its material characteristics, production process, and strict quality control measures. The following is a detailed analysis of the fire resistance guarantee of magnesium oxide board:

1、 Material characteristics

Non combustible: Magnesium oxide board is a non combustible material, mainly composed of magnesium oxide, which is an inorganic mineral material with extremely high fire resistance. Even at high temperatures, magnesium oxide does not undergo combustion reactions, ensuring the fire resistance of the board.

High temperature resistance: The melting point of magnesium oxide is as high as 2800 ℃, which allows the magnesium oxide board to remain stable in high temperature environments and will not quickly fail due to temperature rise. In addition, magnesium oxide sheets can absorb a large amount of heat energy at high temperatures, thereby slowing down the spread of fire.

2、 Production process

Raw material selection: When producing magnesium oxide sheets, it is necessary to choose high-quality magnesium oxide and other additives as raw materials. These raw materials need to comply with national building materials industry standards to ensure the quality and performance of the board.

Forming and curing: After mixing, forming and other process steps, magnesium oxide sheets need to be cured under specific conditions. During the maintenance process, it is necessary to control parameters such as temperature and humidity to promote the internal chemical reactions of the board and enhance its fire resistance.

Surface treatment: In order to improve the fire resistance of magnesium oxide board, special treatments such as spraying fireproof coatings can also be applied to its surface. These measures can further enhance the fire resistance time and fire resistance limit of the board.

3、 Quality control measures

Strict inspection: During the production process, each process needs to be strictly inspected to ensure that the various performance indicators of the board meet the standard requirements. This includes multiple aspects such as fire resistance, compressive strength, and flexural strength.

Regular sampling inspection: In order to ensure stable and reliable product quality, it is also necessary to conduct regular sampling inspections on finished products. The sampling results will serve as an important basis for evaluating product quality and guiding adjustments and improvements in the production process.

4、 Advantages in practical applications

High fire rating: Due to its excellent fire resistance, magnesium oxide board can usually achieve a fire rating of A1 (the highest level), meeting the requirements of various building fire protection regulations.

Long service life: Magnesium oxide board not only has good fire resistance, but also has the advantages of strong durability and long service life. This makes it widely used in various building decoration and renovation projects.

In summary, the fire resistance of magnesium oxide board is ensured through its material characteristics, production process, and strict quality control measures. These measures work together to make magnesium oxide board a building decoration material with excellent fire resistance.
