Recently, many customers contacted us and asked us about the problems they encountered in the use of aluminum silicate ceramic fiberboard. I hope we can help. Today, Xiaobian will discuss with you about the knowledge of aluminum silicate ceramic fiberboard in these problems, hoping to bring inspiration and help to our customers and friends, Let us have a deep understanding of aluminum silicate ceramic fiberboard. In this way, we can know well when we use it in the future, take our time, and give full play to the greatest role of aluminum silicate ceramic fiberboard.
In the application of aluminum silicate ceramic fiberboard for many years, it is often found that the actual temperature does not exceed the service temperature range of the material, but the fiber material has serious shrinkage and pulverization. Through the inspection of chemical composition, Al2O3 meets the product requirements, while SiO2 is low, and the contents of Fe2O3, Cao, MgO, Na2O, K2O and other impurities seriously exceed the standard. 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 fiber material by nearly 100 ℃.
Therefore, when selecting aluminum silicate ceramic fiberboard, we should not only test the composition of Al2O3, but also strictly control the impurity content.
