摘　　要：研究了影响KC-15发泡剂泡沫稳定性的几种因素。结果表明:KC-15发泡剂的最佳浓度为1.5%,此时泡沫粒径分布合理,泡沫骨架稳定;p H值的提高会极大加快泡沫的初始排液速度,生成的泡沫中大泡与小泡数量增加,粒径分布趋于分散;黏度增大会提高泡沫的初期稳定性,但后期稳定性降低,黏度越大,泡沫的平均粒径越小。Studied several factors which influence the stability of KC-15 foaming agent.The results show that：the optimal dosage of KC-15 foaming agent is 1.5％.The bubble size distribution is reasonable and the foam skeleton is stable.The increase of pH value can greatly improve the bubble initial drainage rate and increase the number of large and small bubble.Particle size distribution tends to be scattered.The increase of viscosity will increase the initial stability of the foam,but will reduce the late stability.The greater of the viscosity,the smaller of the average particle size of the bubble.
