近期通過對生產防火板的用戶調查，很多客戶在做防火板產品時，為了降低生產成本，不注意輕燒鎂粉的含量和氧化鎂的活性,以為哪個含量的氧化鎂都可以，尤其在夏季不注意氧化鎂含量，直接導致產品凝固慢，制造出的產品沒拉力沒韌性 。希望廣大防火板用戶在夏季用高含量 高活性的輕燒氧化鎂粉，以去除產品沒硬度等客觀性問題。
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.
