Low-density calcium silicate board prepared from ardealite solid waste and preparation method of low-density calcium silicate board
The invention discloses a low-density calcium silicate board prepared from ardealite solid waste and a preparation method of the low-density calcium silicate board. The preparation method comprises the following steps: (1) preparing the following raw materials in parts by weight: 60-70% of phosphogypsum, 10-20% of cement, 5-20% of blast furnace slag, 5-10% of quartz powder and 5-10% of reinforced fibers; adding water into the raw materials, stirring to prepare mixed blank forming slurry, and controlling the total calcium-silicon molar ratio of the raw materials to be 0.6-0.9 and the pH value of the system to be 9-10; and (2) filtering water on the mixed blank forming slurry through a headbox to prepare a thin wet material layer, rewinding the thin wet material layer through a forming cylinder to form a wet plate blank, then carrying out plate compaction treatment on the wet plate blank, and carrying out pre-curing and autoclaved curing to obtain the low-density calcium silicate plate. The calcium silicate board prepared by taking the acidic solid waste ardealite as the main raw material has the characteristics of low density and high strength, and is good in product performance and low in production cost.
本发明公开了一种利用磷石膏固体废弃物制备的低密度硅酸钙板及其制备方法。该制备方法包括如下步骤：(1)按重量份数计，准备原料：磷石膏60～70％，水泥10～20％，高炉矿渣5～20％，石英粉5～10％，增强纤维5～10％；然后将原料加水搅拌制成混合成坯浆料，并控制原料总钙硅摩尔比为0.6～0.9，体系pH为9～10；(2)将混合成坯浆料经流浆箱上网滤水制备成薄湿料层，经成型筒复卷形成湿板坯，然后将湿板坯进行板材压实处理，再经预养和蒸压养护，得到低密度硅酸钙板。本发明中以酸性固体废弃物磷石膏作为主要原料，制备的硅酸钙板具有低密度、高强度的特点，产品性能好，生产成本低。
