抄録

The effect of aluminum stearate (Al-St) on the dispersity of carbon black in benzene was studied. Channel black, furnace black and thermal black were used. Sedimentation velocity of carbon black was measured at various concentration of Al-St, and the apparent particle size was obtained according to the equation of Stokes. The concentration, required to disperse the carbon black, Cd, varied with St/Al ratio and the sort of carbon black. When St/Al ratio increased from 1 to 2, Cd decreased, but when St/Al ratio was greater than 2, it decreased for channel black, remained to be almost constant for thermal black and increased for furnace black. Flocculation of carbon black with Al-St was also observed. The concentration, Cf, at which the apparent particle size was maximum, were slightly lower than Cd. The effect of monosoap on the flocculation was greater than disoap for channel black and thermal black, but for furnace black, the particle size at Cf was about the same as that in pure benzene.
