| Abstract:The aramid fiber and fabrid were rather easily flocculated in water medium, thus improving the dispersion of aramid fibers has become the major task. Polyethylene oxide has been widely used in the manufacture of synthetic fiber based paper as one kind of nonionic dispersant. In this paper MATLAB software was introduced to deal with the aramid fiber slurry system, then the gray histogram and mean-square deviation of distribution were obtained, the influences of polyethylene oxide on slurry system sedimentation performance and cationic demand were also studied. The results showed that when the dosage of polyethylene oxide was 0.5%, the dispersion and stability of the aramid fiber suspension was the best． |
