Foam stability is affected by several factors. Onefactor which is stable thin sandwich, sandwich the liquid inside can’t bedischarged or discharged slowly. Also electrostatic repulsion occupy themezzanine between ionic surfactants also prevents the bubble burst. Another factorprompting the foam stabilizer is Gibbs elasticity. By stretching a film havinga surface-active substance, such an elastic effect will be shown. In this case, thesurface of the double layer is expanded, resulting in local concentration ofthe surfactant reduces the surface tension rises. The film is stretchedlike an elastic layer of the skin, like poly interference, Shidao surfacetension as low as possible.
