コロイド懸濁液の一方向乾燥過程における体積分率変化に及ぼす界面活性剤の影響

抄録

When a surfactant is added to a colloidal suspension, the shape of the particle precipitate after drying changes depending on the type of surfactant. In this study, a one-way drying model that simplifies the drying phenomenon was introduced for suspensions with CTAB. the volume fraction measurement method using the Lambert-Bael rule was applied to colloidal suspensions with CTAB to evaluate the transition of the solid-liquid layer boundary due to one-way drying. In unidirectional drying, CTAB did not affect the rate of transition of the solid-liquid layer.
