直流电弧等离子体熔化玻璃配合料

摘要

为了探究等离子体在玻璃熔制中的应用,我们采用直流电弧等离子体对玻璃配合料进行熔化,研究了不同功率下配合料的熔化情况.利用X射线衍射(XRD)、扫描电镜(SEM)、热质联用(TG-MS)、X射线荧光光谱(XRF)等手段对样品的结构、断面形貌、质量变化、成分进行表征.结果表明:随着等离子体功率的增加,样品的玻璃化程度提高,质量损失增大,熔化后样品的成分变化较小.等离子体的使用可显著提高玻璃熔化过程中的热交换效率,实现了配合料的快速熔化.%In order to study the application of plasma in glass melting,we employed DC arc plasma to melt a glass batch,and investigated the melting behavior of the batch atdifferent power.The structure,fracture morphology,mass loss,chemical composition of the samples were characterized by X-ray diffractometry (XRD),scanning electron microscope (SEM),thermogravimetric mass spectroscopy (TG-MS)and X-ray Fluorescence (XRF).The results show that the vitrification degree and the mass loss all increase with the increasing power,and the chemical composition of the samples varies only in a very narrow range.It is concluded that the plasma application can improve heat exchange efficiency remarkably,and can help realize the fast melting of the glass batch.
