摘要： 为研究高速剪切法制备干水灭火剂的物料配比、搅拌转速、搅拌时间3个关键工艺参数对制备过程及产品性质的影响，根据响应面实验分析方法，设计了17组对比实验，分别测量了不同参数条件下制备所得的干水产品的松密度、流动性、含水率以及保水性等性能参数。实验结果表明：物料配比、搅拌转速、搅拌时间这3个因素对于产品粉体的松密度、流动性、含水率以及保水性等物理性质影响显著，且具有较强的交互作用。将实验数据进行回归拟合，建立了各性能参数与工艺参数之间的函数模型，并得出了最优制备参数是物料配比为6∶100 ， 搅拌转速为6 000 r/min，搅拌时间为2 min。

Abstract: In order to study the influence of 3 process parameters including material ratio, mixing speed and mixing time on the preparation process and product properties of dry water fire extinguishing agent prepared by high-speed shear method, 17 groups of comparative experiments were designed according to the response surface analysis method, and the performance parameters such as bulk density, fluidity, moisture content, and water retention of the dry water products prepared under different preparation parameters were measured.The experimental results showed that the of material ratio, the stirring rate, and the stirring time have significant effects on the bulk density, fluidity, moisture content, and water retention of the product powder, and have strong interactions. By regression fitting the experimental data, the function model between the performance parameters and process parameters was established, and the optimal preparation parameters are obtained as follows: the material ratio is 6:100, the stirring speed is 6 000 r/min, and the stirring time is 2 min.
