1. After dissolving in water, magnesium sulfate, a building material, can react with lightly burned powder to form magnesium oxysulfide cement. Magnesium oxysulfide cement has good fire resistance, thermal insulation, durability and environmental protection. It is used in many fields, such as fire door core board, external wall insulation Cup, silicon modified insulation board, fire board and so on
