High-silicon system ceramsite and preparation method thereof
The invention relates to the technical field of ceramsite, and particularly discloses high-silicon system ceramsite and a preparation method thereof. The preparation method comprises the following steps: adopting potassium hydroxide as a first exciting agent, firstly activating fly ash, then adding coal gangue, tungsten tailings, urban sludge and a second exciting agent prepared from quick lime, ammonium chloride and gypsum according to a specific proportion, adding the exciting agents in two times, controlling the reaction rate, and preparing the high-silicon system ceramsite. According to the method, the high-silicon ceramsite can be effectively controlled, harmful pores can be effectively reduced, meanwhile, a bacillus pasteurii bacterial solution is used for replacing deionized water for spraying, formed ceramsite is prepared, the strength of the high-silicon ceramsite is improved through bacillus pasteurii, and the high-silicon ceramsite is obtained through room temperature-steam curing. Effective utilization of solid waste is achieved, and energy consumption in the preparation process is low. The high-silicon ceramsite prepared by the invention has the advantages of high cylinder compressive strength, large bulk density, low water absorption and high softening coefficient.
本申请涉及陶粒技术领域，具体公开了一种高硅体系陶粒及其制备方法。一种高硅体系陶粒及其制备方法，采用氢氧化钾为第一激发剂，先活化粉煤灰，再通过加入煤矸石、钨尾矿、城市淤泥和由生石灰、氯化铵和石膏按特定比例组成的第二激发剂，通过分两次加入激发剂，控制反应速率，可有效控制高硅系陶粒的孔隙，减少有害孔，同时以巴氏芽孢杆菌菌液代替去离子水进行喷雾，制备出成型陶粒，利用巴氏芽孢杆菌提高高硅体系陶粒的强度，通过室温‑蒸汽养护，获得高硅系陶粒。实现了固体废弃物的有效利用，且制备过程中能耗较低。本申请制得的高硅系陶粒具有筒压强度高，堆积密度大，吸水率低，软化系数高的优点。
