The factors that influence the stability of three-phase foam, are the particle size of solid, solid concentration, hydrophobicity of particle and viscosity.
研究表明，影响三相泡沫稳定性的因素主要有颗粒大小、固体浓度和颗粒的疏水性。

The higher density of the foam is the better. Check the foamparticle frequently, if its size is not uniform, maybe some problems happened, e. g., jam in the pipe, leakage or mechanical trouble.
