| 摘 要： | 对Ｐｌｕｒｏｎｉｃ、ＡＰ型、ＡＥ型３种聚氧乙烯－聚氧丙烯嵌段共聚物系列的泡沫稳定性及消泡性能进行了测定。结果表明，它们的泡沫稳定性都较差，但有较好的消泡作用。ＡＰ型是较好的消泡剂，ＡＥ型及Ｐｌｕｒｏｎｉｃ中聚氧丙烯含量较高的品种亦有很好的消泡能力。

| Abstract: | The foam stability and defoaming ability of three types of polyoxyethylene-polyoxypro-pylene block copolymers(Pluronic, AE type, AP type)were tested.Poor foam stability andgood defoaming ability were observed for all types of block copolymers.AP type is a betterdefoamer, while AE type and Pluronic species with higher PPO content are also effectivedefOamers. |
