摘要
PU聚氨酯生产中重要物料聚酯多元醇,其羟值大小测定的准确性是确定浆料产品质量、生产工艺的前提条件,酰化法是传统的并适用于工业化生产检验羟值的化学分析法,体系中酰化试剂水份存在对聚酯羟值的大小有很大影响。酰化试剂中水份含量不大于0.30%为最佳有效的生产控制条件。
PU polyurethane production of important materials in the polyol, the hydroxyl value of the size of the accuracy of the determination is to determine the slurry product quality, a prerequisite for the production process, acylation method is applicable to traditional and industrial production of hydroxyl value of the chemical test analysis , acylation reagent water system, the existence of hydroxyl value of polyester have a great impact on the size. Acylation reagents in the moisture content of not more than 0.30 % for the best conditions for effective production control.
