摘要： 利用Ross-Miles泡沫仪对脂肪醇聚氧乙烯醚羧酸钠(C12~14E9C)与异构脂肪醇聚氧乙烯醚(IC10EO8)复配体系的泡沫性能进行了研究。结果表明,复配体系具有良好的发泡力,当C12~14E9C与IC10EO8的质量比为6∶4,复配体系质量浓度为2 g/L时,体系的能量最低,发泡力最强,且随质量浓度继续增加,泡沫稳定性明显变差;复配体系具有强的抗硬水能力,在水硬度为400 mg/kg以下时,体系的发泡力和泡沫稳定性不随水硬度变化;盐的加入对体系的发泡力基本没有影响,但氯化钠和柠檬酸三钠的加入质量分数为0.5%时就会大大降低体系的泡沫稳定性;温度升高,体系的发泡力增加,泡沫稳定性降低;pH增大,体系的发泡力呈增加趋势,pH＞5时发泡力基本保持不变,pH=3~9时体系的泡沫稳定性变化不大。

Abstract: Foaming performance of the blend system of sodium fatty alcohol ether carboxylate (C12~14E9C) and iso-fatty alcohol-polyoxyethylene ether (IC10EO8) were measured by Ross-Miles method.The results showed that the blend system exhibits high foaming power,and the surface energy of the system is the lowest when the mass ratio of C12~14E9C to IC10EO8 is 6∶4 and the mass concentration is 2 g/L.As the mass concentration is further increasing,the foam stability of the blend system becomes declining obviously.The blend system exhibits strong resistance to hard water.Its foaming power and foam stability do not change when the water hardness is less than 400 mg/kg.Addition of salt shows no impact on the foaming power of the blend system,but 0.5% sodium chloride and trisodium citrate can reduce its foam stability.Foaming power of the blend system increases with the temperature increasing,while the foam stability declines.Foaming power of the blend system increases with pH increasing.When pH of the system is higher than 5,its foaming power remains basically unchanged;and when pH is within 3-9,no significant change exhibits on its foam stability.

Key words: sodium fatty alcohol ether carboxylate, iso-fatty alcohol-polyoxyethylene ether, blend system, foaming power, foam stability
