起泡剂通过防止气泡合并来抑制气泡长大，从而产生稳定的泡沫。气泡和粒子的碰撞概率随着气泡的减少而显著增大。在相同体积系统中，大气泡分布产生的气泡较少，小气泡分布产生的气泡较多。本研究旨在将两相体系的泡沫表征参数与三相体... 详细信息

起泡剂通过防止气泡合并来抑制气泡长大，从而产生稳定的泡沫。气泡和粒子的碰撞概率随着气泡的减少而显著增大。在相同体积系统中，大气泡分布产生的气泡较少，小气泡分布产生的气泡较多。本研究旨在将两相体系的泡沫表征参数与三相体系的煤和滑石粉浮选行为相关联。为此，用甲基异丁基碳醇（MIBC）、异辛醇（2乙基己醇）、松油、Dowfroth 250泡沫剂研究单起泡剂体系和双起泡剂体系对气泡聚集的抑制作用。根据单起泡剂的结果，在最低临界聚集浓度为6×10-6时，异辛醇的气泡最小，Sauter平均直径为0.80 mm。通过混合起泡剂Dowfroth 250和松油，气泡尺寸显著减小到0.45 mm。在煤浮选中，单起泡剂和多起泡剂共混物的回收率最高，在两相体系中气泡尺寸最小，但在滑石浮选中没有发现这种关系。
