摘要
从ｚｅｔａ电位的角度，探讨了分散染料在表面活性剂、电解质、酸碱等不同条件下的水溶液中，这些物质对其分散稳定性的影响。试验表明：带负电性较大的分散染料在一定浓度下加入阴离子表面活性剂或阴／非离子表面活性剂复配物后，该体系的稳定性较好。若在染料水溶液中有高价离子的电解质存在时，其稳定性会变差。
In the view of zeta potential, stability of disperse dyes in water solution including surfactants, electrolytes, acids or alkalis and so on is studied in this paper. It is evident from experiments that when an anionic surfactants or a complex of anionic and non ionic surfactants is added to a disperse dye containing larger electronegativity in some concentration, the system has better stability. If there has a electrolyte of high value ion in the water solution of a disperse dye, its stability becomes bad. In addition, pH value of its water solution also has affection on dispersion stability.
