| description | The invention evaluates the hydrophobicity of the powder. In the present invention, a powder is introduced into a mixed solvent comprising a lipophilic solvent and a hydrophilic solvent, the lipophilic solvent is added to the mixed solvent into which the powder is introduced, the voltage rates R of the mixed solvent are measured at predetermined time intervals, and a parameter x related to the concentration of the powder is defined for any voltage rate R. A continuous function HP (x) for the lipophilic solvent ratio corresponding to x is defined. Furthermore, HP (x) for the used x is used as a representative value of the ratio distribution of the lipophilic solvent, and is used as a hydrophobic index.
本发明评价粉体的疏水性。本发明中，将粉体投入由亲油性溶剂和亲水性溶剂组成的混合溶剂中，在投入了粉体的混合溶剂中添加亲油性溶剂，同时每隔规定时间间隔就测定混合溶剂的电压率R，对于任意的电压率R定义与粉体浓度相关的参数x，定义对于与该x对应的亲油性溶剂比率的连续函数HP(x)。而且，将对于所用的x的HP(x)作为亲油性溶剂比率分布的代表值，设为疏水性的指标。 |
