中州铝厂烧结法赤泥“霜”物质研究

The Study on Floating Hoarfrost in Sintered Red Mud of Zhongzhou Aluminum Plant

为了分析赤泥"泛霜"现象的成因,采用X-衍射、扫描电子显微镜、原子吸收等方法研究了中州铝厂各时期烧结法赤泥"霜"物质的化学组成、矿物组成、微观形态等,结果表明,可按溶解性将白色"泛霜"物质分为可溶钠钾盐类与不可溶钙镁盐类,为解决赤泥建材产品"泛霜"问题奠定了理论基础。

In order to analyse the reason of tloating hoarfrost, many experiments were made to research micro-morphology, chemical and mineral composition of the hoarfrost of different periods sintered red mud of Zhongzhou Aluminum Plant by X-diffraction, scanning; electron microscopy, atomic absorption and other methods. The result was that the hoarfrost can be divided into soluble material and insoluble material according to the solubility. It was the theory, to solve the problem about floating hoarfrost of red mud.
