Paints and varnishes — Wettability — Part 4: Determination of the polar and dispersive fractions of the surface tension of liquids from an interfacial tension 油漆和清漆 - 润湿性 - 第4部分:界面张力液体表面张力的极性和分散级分的测定
发布日期: 2024-10-18
本文件规定了一种用光学方法从界面张力测定液体表面张力的极性和色散分数的测试方法。该方法可用于液体涂层材料的表征,特别是如果在替代测量期间发生干燥效应。如果应用于具有非牛顿流动行为的液体(参见ISO 3219-1:20 21,3.22),则可能适用限制。

This document specifies a test method to determine the polar and dispersive fractions of the surface tension of liquids from an interfacial tension with optical methods. The method can be applied for the characterization of liquid coating materials, especially if drying effects occur during alternative measurement. If applied to liquids with non-Newtonian flow behaviour (see ISO 3219-1:2021, 3.22), restrictions can apply.
