Clay-free saw mud foamed ceramic and preparation method thereof
The invention provides a clay-free saw mud foamed ceramic which is characterized by comprising the following raw materials: granite saw mud and municipal sludge. The preparation method comprises the following steps: carrying out wet ball milling, carrying out homogenizing and aging, carrying out spray drying, loading dried and powdered raw materials into a sagger, carrying out high-temperature sintering molding on the sagger and the powder in the sagger, and the like. The method has the advantages that 1, the mixing amount is high, saw mud is utilized in multiple dimensions, solid waste is recycled, the method belongs to an environment-friendly production process, and the social benefit is remarkable; 2, municipal sludge is also a solid waste, so that waste is turned into wealth, and harmonious development of society is facilitated; 3, the recycling of the foamed ceramic leftover material belongs to the recycling of solid waste, the zero emission of the production solid waste is realized, and the large development of sustainable circular economy is fully embodied; 4, full solid waste resource utilization is realized, the technology is high, and the effect is obvious; and 5, all solid waste resources are utilized, the cost of the main raw materials is reduced to the minimum, the main raw materials have zero or even negative purchase expense, and the economic benefit is obvious.
本发明提供了一种无黏土锯泥发泡陶瓷，其特征在于，包括以下原料：花岗岩锯泥、市政污泥。通过湿法球磨、均化陈腐、喷雾干燥、将干燥成粉的原料装入匣钵及将匣钵及匣钵内粉料高温烧结成型等步骤制作。本发明的优点是：1、高掺量、多维度利用锯泥，固废资源化利用，属于环保型生产工艺，社会效益显著；2、市政污泥也是固废利用，变废为宝，有利于社会和谐发展；3、发泡陶瓷边角料回收利用属于固废循环利用，实现生产固废零排放，充分体现可持续循环经济大发展。4、全固废资源利用的发明，技术高超，效果明显。5、全固废资源利用的发明，主原材料成本降到最低，主原料材料零甚至负购买费用，经济效益明显。
