| 摘 要： | 选用Span80、Tween80为石蜡复配乳化剂,采用O-D乳化法与PIT法相结合研究了乳化剂HLB值、乳化剂用量、乳化水加入方式及用量、乳化时间、乳化温度、搅拌方式及搅拌速度对石蜡乳液制备的影响。结果表明,适宜的乳化工艺条件为:复合乳化剂的HLB为10.5,复合乳化剂的用量(M乳化剂/M石蜡)为30%,乳化水用量(M水/M石蜡)为2.5,乳化时间30 min,乳化温度75℃,搅拌速度1 000 r/min。在该条件下可制得具有良好稳定性和分散性的石蜡乳液,粒径单分散性也较好。 |

| Abstract: | Span80,Tween80 were used as emulsifier for wax complex.The influences of the HLB,emulsifier quantity,the dosage and way of adding emulsified water,emulsifying time and temperature,the processes and stirring speed on the preparation of paraffin emulsion were discussed by O-D emulsion process and PIT method.The optimum condition was that the wax emulsion with good stability,dispersibility and monodisperse particle size can be prepared when the HLB is 10.5,the quantity of compound emulsifier is 30%,emulsifying... |
