Light burnt magnesia powder fireproof board is a new product of magnesite technology innovation in recent years. Light burnt magnesia powder fireproof board is applied in the whole country and even in the world. Manufacturers of light burnt magnesia powder fireproof board are all over the world. Light burnt magnesia powder fireproof board is light, fireproof, clean and easy to use. Magnesium oxide content is the key factor in the fireproof board made of light-burnt magnesia powder. Other small chemical indexes of light-burnt magnesia powder also determine the quality of fireproof board made of light-burnt magnesia powder. Selection of qualified and high-grade light-burnt magnesia powder is one of the first conditions for producing high-quality fire-proof panels. Magnesium oxide with high activity is an ideal choice for building fireproof panels.

Recent user surveys on fireproof panels show that in order to reduce production costs, many customers do not pay attention to the content of lightly burned magnesia powder and the activity of magnesia when making fireproof panels. They think that any content of magnesia can be used, especially in summer, without attention to the content of magnesia, which directly leads to the slow solidification of products and the lack of tension and toughness of products. It is hoped that the majority of fireproof board users will use high content and high activity of lightly burned magnesia powder in summer to remove the objective problems such as product hardness.

Magnesium oxide content for fireproof board is recommended: 80%, 85%. The content of ferric oxide should be controlled at a low level, because the fireproof board requires more white color.
