摘要;以碳酸锰为微波吸收材料,考察了微波输出功率、微波辐射时间、样品堆积厚度和样品质量等因
素对微波吸收率的影响。基于单因素条件影响试验结果,采用响应面法进行试验设计、方差分析、曲面
分析及模型优化。结果表明,各因素影响显著程度为:微波功率>样品堆积厚度>样品质量>辐射时
间,且交互影响不显著。当微波功率为675W、作用时间为131.5s、样品堆积厚度为15.4mm、样品质
量为153.6g时,碳酸锰的微波吸收率模拟值最优为6.28%,与实际试验结果(5.89%)能较好吻合,误
差约为6.6%。响应面分析法对矿物微波处理过程的因素影响程度有较好的预测性。

Abstract: Manganese carbonate was used as microwave absorbing materials. The effects of microwave
power, treating time, thickness, and mass of samples on microwave energy absorption rate were investiga
ted. Based on the single factor experimental results, response surface methodology(RSM) was adopted to
design the optimized experiments, analyze the variance and curved surfaces, and to optimize the parameters
of fitted mathematical model. The simulated results indicated that the factors sequenced according to the
significant level were microwave power, thickness, mass of samples and treating time, respectively. The
interaction between the two of these factors was not significant. The optimized conditions were that micro
wave power was 675 W, time was 131.5 s, thickness was 15.4 mm, and mass of samples was 153.6 g
Under these conditions, the predicted absorption rate reached 6.28% by the fitted model, while the actual
experimental value was about 5.89% with a small relative error to the former. Therefore, it showed that
response surface design and its analysis had a good predicted performance in microwave treatment process
of minerais
