以大掺量赤泥为原料经辊道窑烧成的防静电陶瓷及其制备方法
本专利技术涉及一种以大掺量赤泥为原料经辊道窑烧成的防静电陶瓷及其制备方法,属于陶瓷制备
技术介绍
赤泥作为氧化铝行业的副产物,其排放量非常大,我国每年产生的赤泥废弃物达1000万吨,废弃物随意堆放会对大气、水和土壤等环境产生严重影响,因此,发展赤泥的循环利用技术迫在眉睫。赤泥的含铁量高,也含有高温下能够分解的碳酸钙,在将其作为陶瓷原料使用时,赤泥中的铁组分在高温烧成时易形成低熔点的液相,而碳酸盐分解产生的气体会在陶瓷坯体中带来孔隙、在釉料层中带来针孔缺陷,近年来,多是发展利用添加赤泥的方法来生产发泡陶瓷,如ZL201510283089.1公开了一种添加瓷砖废料并经辊道窑烧成发泡赤泥瓷砖的方法,通过调控原料配方,利用高温烧成过程中气体释放行为的控制来生产得到发泡赤泥瓷砖。在不发泡陶瓷的生产过程中,赤泥的添加量一直较低,ZL201210295391.5公开了利用添加15%赤泥原料来生产得到仿古砖,这是因为赤泥含量高给坯体带来高温下降低粘度的熔剂组分就多,高温烧成时陶瓷易变形、过烧,高温下液相出现过早,气 ...
