【摘要】 定量研究了聚醚、F₁₁用量、水分、催化剂、匀泡剂对泡沫流动性的影响。实验结果表明:聚醚、催化剂、匀泡剂对泡沫流动性的影响是显著的,水分对泡沫流动性影响十分敏感,F₁₁用量对泡沫流动性影响有一个转折点,催化剂用量和匀泡剂用量对泡沫流动性影响不大。更多还原

【Abstract】 The effects of poly ether, F₁₁,water,catalyst and surfactant on the mobility of polyurethane rigid foam were studied quantitatively. The experiments show that polyether, catalyst and surfactant have obvious influence on the mobility, water has tremendous effect on it,the amount of catalyst or surfactant has little influence, and there is a turning point on the curve of the amount of F₁₁ with the mobility.更多还原
