The effect of nonionic surfactants on the ultrasonic dispersing of phthalocyanine blue

摘要: The relations between the dispersibility and factors affecting stability of phthalocyanine blue suspensions in aqueous medium presence polyoxyethylene nonylphenol ethers were studied: Namely, 1% was irradiated by ultrasonic wave with addition varying ethylene oxide numbers, effects concentration surfactants, numbers (or HLB), zeta potential, heat wetting investigated. It shown that increase value potential does not necessarily improve pigment, but, above some 12 erg/cm2, amount is linearly related as a whole to except for C9E7.5, which shows an abnormal frequency distribution curve.
