摘　　要：采用气流法研究了十二烷基醇聚氧乙烯醚羧酸钠(C_(12)E_3C)水溶液的泡沫性能,并考察了不同添加剂(氯化钠、聚合物、脂肪醇、烷醇酰胺)对泡沫性能的影响。结果表明,电解质的加入显著降低了泡沫的稳定性,泡沫半衰期从85 min降低至45 min,而起泡能力随电解质浓度的增加先增强后减弱;聚合物的加入降低了起泡能力,但明显增加泡沫稳定性;短链醇的加入可以明显提高溶液的起泡能力及泡沫稳定性,泡沫体积从218 mL最高可增至240 mL,泡沫半衰期从85 min最高可增至108 min;而不同链长的长链醇对泡沫性能影响效果不同;烷醇酰胺的加入则可以增加泡沫稳定性,但对起泡能力影响不大。The foaming properties of sodium lauryl polyoxyethylene ether carboxylate （ C22 E3 C） in the aqueous solution were measured by air flowing method and the effect of different additives, such as sodium chloride, polymers ,fatty alcohols and alkyloamide were investigated. Results showed that the electrolyte deduces the foam stability remarkably. Foam haft - life decreases from 85 min to 45 rain, while the foaming power increases firstly with the increase of electrolyte concentration to a certain extent and then ,drops. The polymer can enhance foam stability while deduce foaming power. The foaming power and foam stability get better with the addition of short - chain fatty alcohols. Foaming power increases from 218 mL to a maximum value of 240 mL and foam half - life increases from 85 rain to a maximum value of 108 min;while the long - chain fatty alcohols show different effects on the foaming properties. The addition of alkyloamide improves the foam stability obviously and shows little effect on foaming power.
