Yang Ning, Yun Bai, Xue-Fan Gu, Gang Chen, Jie Zhang, Zhi-Fang Zhang


In this work, foaming ability of two foaming agents, the stabilizing mechanism of foam stabilizing agent and foam microstructure were studied. The result shows that after joining foam stabilizing agent, foam are still spherical in a long time, difficult to dehydrate, and its half-life is greatly increased. Condensate and Ca2+ have anti-foaming effect all, but its mechanisms are different, condensate oil mainly reducing the half-life, Ca2+ reducing the foam height.1
