When selecting aluminum silicate fiberboard, we should not only check the composition of Al2O3, but also strictly control the content of other impurities. Such impurities are low melting point oxides. Excessive low melting point oxides will reduce the co melting point of aluminum silicate fiber materials. If the content of impurities other than Al2O3 and SiO2 reaches more than 3.5%, the ratio is controlled within 1%, which will reduce the actual service temperature of aluminum silicate fiberboard by nearly 100 ℃.
