摘要
针对耐温耐盐两性表面活性剂的起泡性能和稳泡性能进行研究.通过起泡实验,筛选出了耐温耐盐的起泡剂(TTB、XXB、DSB)和稳泡剂(AEO);然后,对3种起泡剂和稳泡剂的复配体系进行研究,得到了起泡体积较大、稳定性较好的配方;最后,通过泡沫稳定性实验研究了温度以及NaCl、CaCl2在不同矿化度下对泡沫性能的影响.在各实验温度下(20℃、60℃、80℃、90℃),TTB、XXB与AEO系列非离子表面活性剂复配后,起泡体积均有一定程度的下降,随着EO系列表面活性剂浓度的增加,其泡沫稳定性则明显增加.此外,随着EO数的增加,其起泡体积增加,稳定性下降.随着温度的增加泡沫体积增加,稳定性逐渐降低.随Na+、Ca2+浓度的增大,泡沫体积逐渐减小,稳定性增加,但是Ca2+比Na+的效果更加明显.
Abstract
The foaming and foam stabilizing properties of temperature-and salt-resistant amphoteric surfactants were studied.Through the foaming experiment,the temperature and salt resistant foaming agent(TTB,XXB)and foam stabilizer(AEO)were selected,and then the compound system of the three foaming agents and foam stabilizer was studied,and the formula with large foaming volume and good stability was obtained.Finally,the effects of temperature,NaCl and CaC12 on foam properties were studied by foam stability experiments.At each experimental temperature(20℃,60℃,80℃,90℃),the foaming volume of TTB,XXB and AEO series non-ionic surfactants decreased to a certain extent,and the foam stability increased significantly with the increase of the concentration of EO(oxyethylene chain number)series surfactant.In addition,with the increase of EO(oxyethylene chain number),the foaming volume increases and the stability decreases.With the increase of temperature,the foam volume increases and the stability decreases gradually.With the increase of the concentration of Na+and Ca2+,the foam volume gradually decreased and the stability increased,but the effect of Ca2+was more obvious than that of Na+.
