标准范围

从含有不同量的水和相对恒定量的洗涤剂和溶剂的预混料中制备具有所需最终浓度的洗涤剂的干洗溶液。通过visula评估溶液的光密度来确定洗涤剂的溶水能力，并在向仍然澄清的溶液中加水后，确定给定浓度洗涤剂的溶解水含量。通过观察溶液中的相分离来确定洗涤剂的水乳化能力，并且在向认为未分离相的溶液中加水后，确定给定浓度洗涤剂的乳化水含量。

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.
