The research was conducted on the acid-resistance,alkali-resistance and thermal stability of fibers produced by blast furnace slag through the centrifugal method. The mass retention rate was calculated by measuring the mass of the fiber samples before and after the acid-base corrosion. At the same time,the morphology and properties of the fiber were studied by scanning electron microscopy( SEM) and the corrosion mechanism was discussed. The structure and properties of mineral wool fibers were characterized ...
