Light burned magnesia powder is a kind of raw material with medium alkalinity and chemical activity. It is also used in other industrial fields besides being used as refractories and cementitious materials. In addition, the development of converter slag splashing protection technology has further expanded the application scope of light burned magnesia powder. At present, the slag splashing furnace protection technology is mainly used after the light-burned magnesia powder is balled, including light-burned magnesia powder ball, carbon-bearing light-burned magnesia sub-ball and carbon-bearing calcium-containing light-burned magnesia powder ball. Selection of calcination method and control of light calcination temperature are important means to obtain good activity. With the increase of calcination temperature, the specific surface area of MgO decreased significantly.
When the temperature is greater than 1000 ℃, the recrystallization rate of MgO accelerates, the dispersity decreases sharply, and the activity of light calcined magnesia powder is mainly divided into three categories: first, thermoplastic light calcined magnesia powder. Now, the application of Z is mostly EPS thin plastered external wall thermal insulation system, followed by XPS thin plastered external wall thermal insulation system, and then there is a mesh cast-in-place system without mesh, and composite insulation board system; 2、 Thermosetting calcined magnesium powder, polyurethane on-site foaming system, phenolic board; 3、 Inorganic light burned magnesium powder: thermal insulation cotton, rock wool, external wall thermal insulation material, etc. These fire protection properties are different.
