背景技术Background technique
微晶材料，即为微晶玻璃又称微晶玉石或陶瓷玻璃。是综合玻璃，是一种外国刚刚开发的新型的建筑材料，它的学名叫做玻璃水晶。微晶玻璃和我们常见的玻璃看起来大不相同。它具有玻璃和陶瓷的双重特性，普通玻璃内部的原子排列是没有规则的，这也是玻璃易碎的原因之一。而微晶玻璃象陶瓷一样，由晶体组成，也就是说，它的原子排列是有规律的。所以，微晶玻璃比陶瓷的亮度高，比玻璃韧性强。The microcrystalline material, that is, the glass ceramic, is also called microcrystalline jade or ceramic glass. It is a comprehensive glass, a new type of building material that has just been developed in foreign countries. Its scientific name is glass crystal. Glass-ceramics and our common glass look very different. It has the dual characteristics of glass and ceramic. The atomic arrangement inside the ordinary glass is not regular, which is one of the reasons for the fragility of the glass. Microcrystalline glass, like ceramics, consists of crystals, that is, its atomic arrangement is regular. Therefore, glass-ceramics have higher brightness than ceramics and are stronger than glass.
在工业生产中,矿山开采要产生大量的尾矿,冶金工业及无机化工等行业在生产过程中会产生大量废渣,城市垃圾处理会产生大量固体废弃物,这些尾矿和废渣一般采用堆放的方式处理,不仅占用大量土地,还会因渗透而污染地下水资源。另一方面,废弃物主要成分一般以SiO2、Al2O3、CaO、MgO等氧化物形式存在,而这些氧化物也是生产微晶玻璃所需的重要原料。用尾矿和工业废渣生产微晶玻璃,其附加价值高,不仅可以节约资源,减少工业废弃物的排放,减轻环境压力,还可以变废为宝,带来巨大的经济和社会效益,是微晶玻璃研究和生产的一个主要发展方向。In industrial production, mining produces a large amount of tailings. Metallurgical industry and inorganic chemical industry will produce a large amount of waste in the production process. Urban waste disposal will produce a large amount of solid waste. These tailings and wastes are generally stacked. Treatment not only occupies a large amount of land, but also pollutes groundwater resources due to infiltration. On the other hand, the main components of waste generally exist in the form of oxides such as SiO2, Al2O3, CaO, MgO, etc., and these oxides are also important raw materials required for the production of glass ceramics. The use of tailings and industrial waste residue to produce glass-ceramics has high added value, which not only saves resources, reduces industrial waste emissions, reduces environmental pressure, but also turns waste into treasure, bringing huge economic and social benefits. A major development direction in the research and production of crystal glass.
现有的工业废渣生产微晶材料的方法中，对废渣的效率不高。In the existing method for producing microcrystalline materials from industrial waste, the efficiency of the waste residue is not high.
