Technological method for preparing autoclaved bricks from sludge
The invention discloses a process method for preparing autoclaved bricks from sludge, and solves the problems that the sludge cannot be reasonably used and autoclaved building materials do not have environment-friendly adsorption performance at present. The method comprises the following steps: step 1, adjusting and modifying concentrated sludge, adjusting the attribute of the sludge, and adjusting the pH value; step 2, sludge carbonization: carrying out carbonization treatment on the sludge; 3, material mixing and blank making, wherein the materials are mixed and then pressed into a blank; and step 4, performing autoclaved activation, namely performing autoclaved on the blank to prepare the autoclaved brick.
一种利用污泥制备蒸压砖的工艺方法，解决了现在污泥不能合理使用，蒸压建材没有环保吸附性能的问题。其包括如下步骤：步骤一，浓缩污泥调整改性，调整污泥的属性，调节酸碱度；步骤二，污泥炭化，将污泥进行炭化处理；步骤三：物料混合和制坯，将物料进行混合然后压制成坯；步骤四，蒸压激活，将坯进行蒸压，从而制成蒸压砖。
