摘　　要：为研究利用搅拌磨湿法研磨微米粒级熔融石英制备微纳米粒级石英产品的可行性,通过正交实验,分析珠子直径、转速、流量及珠子填充率对研磨效果的影响,结果显示:对研磨石英中位径(d50)的影响显著性顺序为珠子直径>转速>流量>珠子填充率;湿法研磨制备微纳米熔融石英的优化工艺参数组合为珠子直径Φ0.3~Φ0.4 mm、转速1300 r/min(线速度11.56 m/s)、料浆的流量9.5~10.5 L/min、研磨介质填充率72 vol.%,另外,料浆的固含量为50 wt.%。Several parameters(diameter of microsphere,rolling speed,flow rate and filling rate)used in Wet Grinding Method of preparing Nano-Fused Silica were tested by a series of orthogonal experiments.The results show that the influence of the different parameters to the quartz median diameter(d50)should be:diameter of microsphere>rolling speed>flow rate>filling rate.Meanwhile,the optimal parameters of wet grinding method of preparing Nano-Fused Silica were shown atΦ0.3~0.4 mm to microsphere diameter,1300 r/min to rolling speed(linear speed is 11.56 m/s),9.5~10.5 L/Min to flow rate,and 72 vol.%to the grinding medium filling rate.Moreover,the solid content of the slurry is 50 wt.%.
