Process for producing high-strength sintered hollow brick by utilizing tailings
The invention provides a process for producing a high-strength sintered hollow brick by utilizing tailings, and relates to the technical field of hollow bricks. The process comprises the following steps: (1) stirring and crushing river silt, adding water into the crushed river silt, tailing powder, mullite powder, illite powder, rice hull ash and Portland cement for stirring; performing stirring and kneading after aging; performing forming by a two-stage vacuum extruder; (2) naturally drying the hollow brick green body in a room-temperature windless environment, then, putting the hollow brickgreen body into a drying chamber for two-stage drying, and strictly controlling the temperature, the relative air humidity and the flow rate of air; (3) putting the hollow brick dry blank into a furnace for firing, and strictly controlling the heating speed; and (4) performing cooling to room temperature along with the furnace after firing. The tailing powder, the mullite powder, the illite powder, the rice hull ash, the Portland cement and the river mud are reasonably matched, and through an optimized production process, the prepared sintered hollow brick is high in strength, low in water absorption, low in heat conduction coefficient, attractive in appearance and good in sound insulation effect.
本发明提供了一种利用尾矿生产高强度烧结空心砖的工艺，涉及空心砖技术领域；该工艺包括以下步骤：(1)将河道淤泥、搅拌破碎后，与尾矿粉、莫来石粉、伊利石粉、稻壳灰、硅酸盐水泥一起加水搅拌；陈化后搅拌捏练；双级真空挤出机成型；(2)空心砖砖坯在室温无风的环境下自然干燥；再置于干燥室中进行两级干燥，严格控制温度、空气相对湿度、空气的流速；(3)将空心砖干坯入炉烧制，严格控制升温速度；(4)烧制后随炉冷却至室温。本发明中的尾矿粉、莫来石粉、伊利石粉、稻壳灰、硅酸盐水泥、河道淤泥配合合理，并通过优化的生产工艺，使制备得到的烧结空心砖强度高，吸水率低，热传导系数低，外表美观，隔音效果好。
