Anti-erosion zirconium-containing andalusite brick and preparation method thereof
The invention discloses an anti-erosion zirconium-containing andalusite brick and a preparation method thereof. The anti-erosion zirconium-containing andalusite brick is mainly composed of the following raw materials: andalusite of 5-3mm, andalusite of 3-1mm, andalusite of 1-0mm, andalusite of 200 meshes, a zirconium source and clay. In addition, a binding agent is added. The method comprises the following steps: firstly, uniformly mixing the andalusite of 5-3mm, 3-1mm and 1-0mm, then adding the binding agent, and performing uniform mixing to obtain a mixed material A; uniformly mixing 200-mesh andalusite, the zirconium source and the clay to obtain a mixed material B; and adding the mixed material B into the mixed material A, uniformly mixing, carrying out compression molding on the obtained total mixed material, performing drying, and finally performing sintering and cooling to obtain the product. The product prepared by the method has excellent erosion resistance, permeation resistance and thermal shock resistance, is suitable for rotary kilns and oversize cement kilns for co-processing hazardous wastes, and has a service life of more than 15 months.
本发明公开了一种抗侵蚀含锆红柱石砖及其制备方法。所述抗侵蚀含锆红柱石砖主要由原料5～3mm的红柱石、3～1mm的红柱石、1～0mm的红柱石、200目的红柱石、锆源和粘土组成；另外加入结合剂。首先将5～3mm、3～1mm和1～0mm的红柱石混匀，然后加入结合剂混匀，得到混合物料A；将200目红柱石、锆源和粘土混匀，得到混合物料B；混合物料B加入混合物料A中混匀，所得总混合物料压制成型、干燥，最后烧成冷却，得到产品。利用本发明制备所得产品具有优良的抗侵蚀、抗渗透和抗热震性能，适用于协同处置危险废弃物回转窑以及特大型水泥窑，使用寿命达到15个月以上。
