标准范围

本国际标准规定了一种测量水中微量基本物质的方法用于生产聚氨酯的聚醚多元醇。了解溶液中微量碱度是很重要的防止聚氨酯预聚物生产过程中反应物凝胶化的多元醇。它也很有用控制用于聚氨酯生产的多元醇的碱度，以确保反应的一致性和可重复性行为该方法适用于质量控制、规范测试和研究。适用范围为0 _g/g至50 _g/g，以KOH表示。该方法不适用于胺基多元醇。这些值可以报告为CPR（可控聚合速率）单位。

This International Standard specifies a method for the measurement of trace amounts of basic materials present inpolyether polyols used in the production of polyurethanes. It is important to know the trace amount of basicity in apolyol to prevent gelation of the reaction mass during the production of polyurethane prepolymers. It is also usefulto control the basicity in polyols used for polyurethane production to assure consistent and reproducible reactionbehaviour. This method is suitable for quality control, as a specification test and for research.The applicable range is 0 _g to 50 _g/g, expressed as KOH. The method is not applicable to amine-based polyols.The values may be reported as CPR (controlled polymerization rate) units.
