Foamat泡沫起升仪在聚氨酯硬泡催化剂测试中的应用

Application of Foamat Foam Rising Instrument in Catalyst Testing of Rigid Polyurethane Foam

通过Foamat泡沫起升仪研究了不同的发泡、凝胶和三聚催化剂对某相同基础配方聚氨酯硬泡反应参数影响。通过对Foamat泡沫起升仪测试的发泡速度曲线、高度变化曲线及相应数据的分析,表征相应催化剂的催化效果,从而完成对催化剂的测试与筛选工作。

The effects of different foaming,gelling and trimerization catalysts on the reaction parameters of a basic formula of rigid polyurethane foam were studied by the Foamat foam rising instrument.The catalytic effect of the catalysts was characterized by analyzing the foaming speed curves and height curves and relevant data.The testing and filtrating of the catalysts were achieved.
