由于起泡剂研究工作的进展,起泡剂作用的新概念打破了传统的看法。过去对起泡剂作用的传统概念是:把两相接触推广到三相接触,并认为起泡剂是表面活性物质,形成气泡的原因是由于液-气界面表面张力的降低,同时能产生大量泡沫并有利于浮选的就是好起泡剂。但是,三相接触研究证明,有些药剂如双丙酮醇,在液-气界面并无活性,单独使用也不起泡,而与捕收剂
Due to the progress of research on frothers, the new concept of frothers has broken the traditional view. In the past, the traditional concept of the action of a foaming agent was to generalize the two-phase contact to three-phase contact and to regard the foaming agent as a surface-active substance. The reason for the formation of bubbles is due to the reduction of the surface tension of the liquid-air interface, Foam and flotation is good foaming agent. However, three-phase contact studies have shown that some agents, such as diacetone alcohol, have no activity at the liquid-air interface and do not blister when used alone,
