Method for preparing baking-free brick from secondary aluminum ash
The invention discloses a method for preparing a baking-free brick from secondary aluminum ash, and relates to the technical field of harmless treatment of secondary aluminum ash hazardous waste, and the treatment method comprises the following steps: grinding secondary aluminum ash and apatite in a certain proportion through a ball mill; and mixing the ground mixture powder with tap water, an exciting agent, an early strength agent and a gelling agent in proportion for reaction, putting the obtained reactant into a mold for compaction, demolding and curing to finally obtain the baking-free brick. According to the treatment method disclosed by the invention, the harmful substance, namely the secondary aluminum ash, can be efficiently turned into wealth, the adverse effect on the environment is reduced, the utilization rate of resources is greatly improved, and harmless treatment is realized.
本申请公开一种二次铝灰渣制备成免烧砖的方法，涉及二次铝灰渣危废无害化处理技术领域，该处理方法如下：将二次铝灰渣与磷灰石成一定比例通过球磨机研磨。将研磨后的混合物粉末成比例的与自来水、激发剂、早强剂、凝胶剂共同混合反应，将得到的反应物放入模具中压实，脱模后进行养护，最终得到免烧砖。本发明的处理方法能够高效实现将二次铝灰渣这种有害物质变废为宝，减轻对环境的不良影响，极大程度上提高了资源的利用率，并实现无害化处理。
