Method for preparing fiber cement slab from industrial tailing slag
The invention discloses a method for preparing a fiber cement slab from industrial tailing slag. The preparation method comprises the following steps of putting 5-10 parts by weight of wood pulp fibers, 15-50 parts by weight of cement, 20-55 parts by weight of lithium slag, 10-30 parts by weight of graphite tailings and 3-5 parts by weight of an additive into a crusher and crushing the raw materials into a powdery mixed raw material. According to the method for preparing a fiber cement slab from industrial tailing slag, an intermediate chelating agent is adopted, the chelating effect of heavymetal is utilized, a capillary energy conveying channel is blocked, the activated state of the intermediate chelating agent is converted into a stable state, and then the long-term stability of a stabilized product is improved; and after the solid waste is modified, the kinetic energy of chemical reaction is reduced, the reaction activity of the material is reduced, the weather resistance of the solid waste (graphite tailings, lithium slag and the like) material is improved, and different types of green building construction new materials can be formed according to requirements by using a multistage super-strong consolidation material and a graded reinforced solid waste sealing technology.
本发明公开了一种工业尾矿渣制备纤维水泥平板的制备方法，包括将5‑10重量份数的木浆纤维、15‑50重量份数的水泥、20‑55重量份数的锂渣、10‑30重量份数的石墨尾渣以及3‑5重量分数的添加剂，放入粉碎机中粉碎成粉末状的混合原料，该种工业尾矿渣制备纤维水泥平板的制备方法，采用了中间体螯合剂，利用重金属的螯合作用和堵塞毛细能量输送通道，使其由活化态转变成稳定态，进而提高稳定化产物的长期稳定性；固体废弃物经改性处理后，降低了化学反应动能，降低材料反应活性，提高了固体废弃物（石墨尾渣、锂渣等）材料的耐候性能，多级超强固结材料，分级强化封固固废技术也可根据需求形成不同种类的绿色建筑施工新材料。
