Aerated concrete foaming agent
The invention relates to the technical field of aerated concrete foaming agents, and discloses an aerated concrete foaming agent, which comprises the following composition materials: waste silicon powder; a porous silicon structure treatment liquid; the porous silicon structure treating fluid comprises the following materials: 0.01 mol/L of Cu (NO3) 2; the concentration of HF is 0.5 mol/L; the concentration of H2O2 is 0.1 mol/L; and the concentration of CH3COOH is 0.5 mol/L. Compared with the conventional foaming agent aluminum powder, the waste silicon powder foaming agent adopted by the aerated concrete foaming agent disclosed by the invention is lower in cost and higher in gas generation amount, and resource utilization of the waste silicon powder can be realized; compared with untreated silicon powder foaming, the porous-structure waste silicon powder foaming agent has the advantages that the agglomeration degree is reduced, the specific surface area is large, the reaction activity is improved, the foaming rate of the foaming agent is increased, the surface of the silicon powder is of a porous structure, the specific surface area is increased, and therefore the purpose of improving the chemical activity of the waste silicon powder is achieved; the high-activity waste silicon powder is beneficial for improving the foaming efficiency of the novel aerated concrete foaming agent.
本发明涉及加气混凝土发气剂技术领域，且公开了一种加气混凝土发气剂，所述加气混凝土发气剂包括以下组成物料：废硅粉；多孔硅结构处理液；所述多孔硅结构处理液包括以下组分的物料：Cu(NO3)20.01mol/L；HF0.5mol/L；H2O20.1mol/L；CH3COOH 0.5mol/L。该加气混凝土发气剂，与常规发泡剂铝粉比较，本发明采用的废硅粉发泡剂成本更低、发气量更高，且能实现废硅粉资源化利用；与未处理硅粉发泡比较，本发明的多孔结构废硅粉发气剂的团聚度降低，比表面积大，反应活性提高，有利于提高发泡剂的发泡速率，通过使硅粉表面呈多孔结构，增加其比表面积，从而达到提高废硅粉的化学活性的目的，高活性的废硅粉有利于提高该新型加气混凝土发气剂的发气效率。
