摘　　要：通过改变浆料中无机电解质/阳离子聚酰胺-环氧氯丙烷树脂(PAE)的浓度,采用德国Mütek公司SZP-10型Zeta电位仪测量对比浆料Zeta电位及电导率的变化,研究无机电解质对含PAE浆料Zeta电位及电导率的影响。实验表明:随着Na+/Ca2+/Mg2+浓度的增加,浆料Zeta电位绝对值逐渐下降;随着导电离子浓度的增多,浆料电导率逐渐升高。随着PAE用量的增加,浆料的Zeta电位逐渐增加,当用量达到一定值后,Zeta电位的电性发生反转,由负变正,再继续增加PAE用量后,浆料Zeta电位继续升高。PAE用量固定在1%时,随着Na+/Ca2+/Mg2+浓度的增加,浆料的Zeta电位逐渐降低,电导率逐渐升高。Through measuring the change of pulp Zeta potential and conductivity by Germany Mütek SZP- 10,effect of inorganic electrolytes and PAE concentration on pulp Zeta potential and conductivity was studied. The result showed that the absolute value of pulp Zeta potential decreased gradually with Na＋/ Ca2 ＋/ Mg2 ＋concentration increased,as ion concentration increased while conductivity increased. With the increasing of PAE concentration pulp Zeta potential decreased gradually,when it reach a certain amount,Zeta potential electricity would change from negative to positive,and as the dosage of PAE continues increasing,the pulp Zeta potential would keep rising. When the amount of PAE was constant at 1%,pulp Zeta potential increased and conductivity decreased as Na＋/ Ca2 ＋/ Mg2 ＋concentration increased.
