表面活性剂 在干洗溶剂中的水分散力

[中文适用范围]： 由含有不同量的水和相对恒定量的洗涤剂和溶剂的预混物制备具有所需洗涤剂最终浓度的干洗溶液。 洗涤剂的水溶解能力通过溶液的光密度的视觉评估来确定，并且在向仍然澄清的那些溶液中添加水之后，测定给定浓度的洗涤剂的溶解水含量。 洗涤剂的水乳化能力是通过观察溶液中的相分离来确定的，并且在将水添加到被认为其中相未分离的那些溶液中之后，测定给定浓度的洗涤剂的乳化水含量。 [外文原描述]： From premixes containing different amounts of water and relatively constant amounts of the detergent and solvent dry cleaning solutions with the desired final concentration of detergent are prepared. The water solubilizing power of the detergent is determined by visula assesment of the optical density of the solutions, and, after adding water to those solutions that are still clear, the solubilized water content for a given concentration of detergent is determined. The water emulsifying power of the detergent is determined by observation of phase separation in the solutions, and, after adding water to those solutions in which the phases are considered not to have separated, the emulsified water content for a given concentration of the detergent is determined.
