摘要: 以中国石油抚顺石油一厂生产的58号全精炼蜡为主要原料,SP-60、TW-80等为乳化剂,采用剂在油中法制得了乳化蜡。首次采用浊度比法对乳化蜡稳定性进行分析,并将其结果与室温静置法相比较。结果表明,用浊度比法判定乳化蜡的稳定性简单快捷、准确性高,具有很高的实用价值。通过浊度比方法考察了乳化温度、乳化时间、HLB值和乳化水用量四种工艺条件对石蜡乳液制备的影响。实验结果表明,制备乳化蜡的优化配方及工艺条件为:乳化温度70 ℃,乳化时间为50 min,复配乳化剂的HLB值为10,乳化水用量为75%。

Abstract: Emulsifying wax samples were prepared by the method of emulsifier in oil using 58# full refining wax from the No.1 Refinery of CNPC Fushun Petrochemical Company as main raw material, TW-80 and SP-60 as complex emulsifier. Turbidity ratio measurements were introduced to study the stability of emulsifying wax samples firstly, and the test results were compared with the room temperature static method. Results showed that using turbidity ratio method to determine the stability of emulsifying wax is feasible, besides, it is simple, quick and with high accuracy. The effect of emulsifying temperature, emulsifying time, water amount and HLB value of emulsifier on the stability of prepared wax emulsion was studied and the optimum preparation conditions were obtained as follows: an emulsifying temperature of 70 ℃, an emulsifying time of 50 min, emulsifier HLB value of 10 and water amount of 75%.
