Morphologies and characteristic of glass fiber suspensions basing on various beating speeds

Abstract

Glass fibers commonly flocculate in suspensions and slurries, which can be largely prevented by a beating process. In this paper, morphologies and characteristics of glass fiber suspensions resulting from various beating speeds are explored. By increasing the speed (ranging from 1500 revolutions to 12000 revolutions), glass fibers can be translated, rotated, bended and broken, which leads the drainage resistances of glass fiber suspensions increase dramatically from 19.5 °SR to 23.5 °SR, then fluctuate and settle close to 22.5 °SR. Decreasing the fiber length leads to reduction in fiber–fiber contact and improves the uniformity of fiber suspensions. The separation and random distribution of glass fibers decreases in the viscosity of the fiber suspension.
