Sponge brick produced from aluminum ash and preparation process thereof
The invention belongs to the technical field of building materials, and particularly relates to a sponge brick produced from aluminum ash and a preparation process of the sponge brick, and the sponge brick produced from the aluminum ash is prepared by taking the aluminum ash as a main raw material and adding a pore forming agent, a fluxing agent, a high-temperature binding agent and a forming binding agent as auxiliary materials. According to the invention, the aluminum ash in the electrolytic aluminum industry can be effectively consumed, on one hand, the problem of environment-friendly discharged waste disposal of electrolytic aluminum enterprises is solved, on the other hand, efficient utilization of resources is realized, on the other hand, sponge brick products with good market prospects are provided, and the economic benefit, the environment-friendly benefit and the social benefit are very remarkable; meanwhile, the problem of fluorine pollution of the aluminum ash can be well solved, fluorine and aluminum-silicon-calcium in the aluminum ash form fluorosilicate glass with stable chemical properties at high temperature, and fluorine is not dissolved out any more.
本发明属于建筑材料技术领域，具体涉及一种铝灰生产的海绵砖及其制备工艺，所述的铝灰生产的海绵砖，以铝灰为主要原料，添加造孔剂、助熔剂、高温结合剂和成型粘结剂为辅料制得。本发明可有效消耗掉电解铝行业的铝灰，一方面解决了电解铝企业环保排放废料处置的问题，一方面实现了资源的高效利用，再一方面提供了市场前景良好的海绵砖产品，经济效益、环保效益、社会效益十分显著；同时可以很好的解决铝灰的氟污染问题，高温下铝灰中的氟和铝硅钙形成化学性质稳定的氟硅酸盐玻璃，氟不再溶出。
