Preparation method and application of acid-resistant brick material
The invention discloses a preparation method and application of an acid-resistant brick material. The preparation method comprises the following steps: with fly ash as a raw material, adding acid, conducting a sufficient reaction, and carrying out solid-liquid separation to obtain a solid phase which is white mud; and drying the white mud, mixing the dried white mud with Al2O3, CaCO3, K2O, Na2O and MgO according to a certain ratio, and carrying out ball milling, molding and roasting successively to obtain an acid-resistant brick. The acid-resistant brick material disclosed by the invention notonly has good mechanical properties and excellent acid corrosion resistance, and can be used as a lining material of a dissolution kettle.
本发明公开了一种耐酸砖材料的制备方法及其应用，本发明以粉煤灰为原料，加入酸充分反应并固液分离，固相为白泥；烘干白泥，将其与Al2O3、CaCO3、K2O、Na2O、MgO按一定配比混合，经球磨、成型、焙烧，制得耐酸砖。本发明的耐酸砖材料不仅具有良好的力学性能，尤其具有优异的耐酸腐蚀性，可以作为溶出釜的内衬材料。
