Light-burned magnesium powder fireproof board is a new product of magnesite technology innovation in recent years. It is economical and practical. Light-burned magnesium powder fireproof board is used in the country and the world. There are many manufacturers producing light-burned magnesium powder. The fire board is lightweight, fireproof, neat and easy to use. The content of magnesium oxide is the key to the finished light-burned magnesium powder fire board, and other small chemical indicators of the light-burned magnesium powder also determine the quality of the light-burned magnesium powder fire board. Selecting qualified high-grade light-burned magnesium powder is one of the first conditions to create a high-quality fireproof board. Highly active magnesia is an ideal choice for making fire boards.

Recently, through user surveys on the production of fire board, many customers do not pay attention to the content of light-burned magnesium powder and the activity of magnesium oxide in order to reduce the production cost of fire board products, and think that any content of magnesium oxide can be used, especially in summer Failure to pay attention to the content of magnesium oxide directly leads to slow solidification of the product, and the manufactured product has no tension and no toughness. It is hoped that the majority of users of fire prevention boards will use high content and high activity of lightly burned magnesia powder in summer to remove objective problems such as lack of hardness of the product.


Recommended content of magnesium oxide for fire board: 80%, 85%. The content of ferric oxide should be controlled low, because the fireproof board requires more white color.
