摘　　要：选用Box-Behnken法以进行抑尘剂配方的优化设计,主要以非离子型表面活性剂烷基多糖苷(APG-10)、阴离子型表面活性剂十二烷基苯磺酸钠(SDBS)和聚丙烯酰胺(APAM)作为响应变量,以沉降时间和透过率作为响应值,建立回归模型,得到表面活性剂和添加剂的优化配比,配制抑尘剂.结果表明:试剂与沉降时间的回归模型中相关系数R_(2)=0.9082,方程的F值为7.69,概率0.0068<0.01;试剂与透过率的回归模型中相关系数R_(2)=0.9190,方程的F值为8.83,概率0.0045<0.01.为此得出了进行煤尘润湿和团聚效果最优的试剂复配质量浓度为:0.17%APG-10、0.49%SDBS及0.05%APAM,沉降时间预测值为34.90 s,透过率预测值为93.73%,在此情况下,可以达到最佳的润湿和团聚效果.In this paper,an optimization design was carried out based on Box-Behnken method for the formula of dust restrain reagent.Picking APG-10,SDBS and APAM as response variables,taking sedimentation time and transmission rate as response values,a regression model was established to get an optimization compound proportion of surfactant and additive for dust restrain reagent modulation.Experiment results show that,when the correlation coefficient R_(2) is 0.9082 in the regression model of reagent and sedimentation time,the F value of the equation is 7.69 and the probability is 0.0068<0.01.And when the correlation coefficient R_(2) is 0.9190 in the regression model of reagent and transmission rate,the F value of the equation is 8.83 and the probability is 0.0045<0.01.The conclusion is that,the best compounding concentration is 0.17%APG-10,0.49%SDBS and 0.05%APAM,the predicted settlement time is 34.9025 s,and the predicted transmittance is 93.7259%,reaching the optimum state of wetting and agglomeration.
