摘要:
硫酸钙晶须是一种正在被广泛应用的添加组分,发挥着日益突出的作用。干燥是制备硫酸钙晶须工艺中的重要步骤。为了探究微波干燥方式对硫酸钙晶须干燥的可行性,首先阐述了微波干燥原理,并且通过以二水硫酸钙晶须为原料的实验,获得在多种主要影响因素条件下半水硫酸钙晶须的实验结果。优化干燥的实验条件为:硫酸钙晶须100g、微波干燥时间25min、微波功率700W,此条件下硫酸钙晶须的相对脱水率达到97%;对样品进行XRD检测,其成分全部为半水硫酸钙晶须,与样品在120℃常规电加热干燥下所得样品成分相同,而微波干燥时间仅为其的加热干1/5。同时,通过材料性能测试实验,证明微波处理的硫酸钙晶须性能得到增强。
Abstract:
Calcium sulfate whisker is a widely used additive composition and it plays an increasingly prominent role.The drying of calcium sulfate whiskers is an important step in the preparation process.To explore the microwavedrying on the feasibility of drying calcium sulfate whisker,this paper firstlyexpounds the principles of microwave drying and through the experiment of CaSO4·2H2O as raw material and under the main factors in a variety of conditions,the experimental results of CaSO4·0.5H2O are obtained,and the optimum areobtained as follows:the weight of calcium sulfate whisker is 100 g,microwave drying time is 25 min,the microwave power is 700 W.Under this condition,the relative dehydration rate is 97%; all of the sample components are CaSO4·0.5H2O by XRD and has the same constitution with conventional electric heating at 120 ℃.Compared with the conventional electrical drying process,themicrowave drying time is only 1/5 of conventional electrical drying's.At the same time,the microwave treatment increased the properties of the calcium sulfate whisker by material performance test.
