摘要/Abstract

摘要： 多相泡沫体系由气液固三相组成，固体颗粒的加入改变了泡沫的形成机制，需要一种新的泡沫体系评价方法来分析固体颗粒对泡沫稳定性的影响。采用Ｗａｒｉｎｇ　Ｂｌｅｎｄｅｒ方法生成泡沫，泡沫体系中液体析出时间和析出体积倒数在双对数坐标系中存在线性关系，因此采用该直线斜率表征泡沫衰减速率。对３种不同起泡剂的泡沫衰减速率进行了研究。结果表明，常规泡沫体系中的泡沫衰减速率只与起泡剂浓度有关，而且起泡剂浓度不同泡沫衰减速率则不同。对固相颗粒类型、粒径、浓度对多相泡沫体系衰减速率的影响进行了研究。结果表明，预交联颗粒能与起泡剂溶液复配出发泡体积高、稳定性强的泡沫体系；固体颗粒粒径越小，多相泡沫体系越稳定；固相颗粒质量分数影响多相泡沫体系的起泡能力，存在最优的固相颗粒质量分数，使多相泡沫体系最稳定。

Abstract: Multi-phase foam system is composed of gas, liquid and solid. The method used to evaluate the effects of particles on foam stability was presented due to the foam formation process altered by particles. Research shows that foam liquid drainage volume was linear with respect to its drainage time in double logarithmic coordinate system, so the slope can be used to characterize foam decay rate. Experiments were conducted to investigate the foam decay rate of 3 foaming agents and the results show that foam decay rate is only related with foaming agent concentration in the general foam system, and it is unchangeable at constant mass fraction. Experiments of the effects of particle category, size and concentration on foam decay rate were also conducted, and the results present that preformed gel particle can be used to combine with foaming agents to form a good multi-phase foam system with high foam volume and half life period; the smaller the particle size the more stable multi-phase foam system, mass fraction of particle has an impact on foam ability, and there is an optimum value for the foam stability.
