| 摘 要： | 提出了一个粉体表面表征的新参数及其测定方法.该参数在数值上等于粉体与水之间的粘附张力对粉体与甲苯之间粘附张力的比值,简称为ATRHL值,表示粉体表面亲水-亲油的程度.该参数用于判断粉体之间相容性,并为选择分散介质提供依据.

| Abstract: | A new parameter, ATRHL (adhesion tension ratio of hydrophilic liquid to lipophilic liquid in contact with powder) used for the characterization of powder surface has been put forward. The measurement of ATEHL for powder is based on the adhesion tension of distilled water and toluene in contact with powder. Thus ATKHL expresses the hydropilic-lipophilic degree of the powder surface. |
