泡沫特性的研究

A STUDY ON FOAM PROPERTIES

本文对石油磺酸钠和十二烷基苯磺酸钠两种起泡剂的起泡性和泡沫半衰期作了研究。结果表明:随着起泡剂浓度的增加,起泡高度和泡沫半衰期也增大,当达到一最大值后,又随浓度的增加而降低;升高一定温度,起泡高度增大,泡沫半衰期减小。在泡沫配制液中加入固泡剂明胶和增粘剂 CMC 后,可使泡沫的稳定性显著提高。三相泡沫的稳定性远大于两相泡沫。

The foaming ability of petroleum sulfonates and dodecylbenzene sulfonate,determined as the height of foam formed,and foam stability,determined as its half-life time,are studied in this paper.Experiments show that these two charactoristics of foam go through a maximum as the concentration of foaming agents in aqueous foaming solution increases.Higher foam height and shorter foam half-life time are observed at higher temperature.The stability of foam is significantly improved when gelatine and CMC are added into the foaming solution, i.e.,triphase foam is more stable than biphase one.
