| titleOfInvention | Fe in iron and steel pickling solution2+And a method of using the same |
| abstract | The invention relates to Fe in a pickling solution 2+ Precipitating agent andthe application method belongs to the field of metal surface pretreatment. Powder, water and additives are used as main raw materials. The powder is from apatite, diatomite, montmorillonite, magnesite, metallurgical tailings and industrial phosphate. The additive is mainly one or a combination of more of polyacrylamide, cellulose derivative, polyamide and polystyrene. Ball-milling the powder to below 300 meshes for later use, mixing the additive with water according to a proportion for later use, adding the powder into a mixed solution containing the additive, and then stirring and preserving heat for 2 hours at 70-90 ℃ to prepare the precipitator. Fe 2+ The precipitator is added into the pickling solution according to the mass fraction of 5-10 wt%, and stands for 10-30 minutes, so that the Fe content of the pickling solution can be remarkably reduced 2+ The purpose of concentration; the method has obvious application value for prolonging the service cycle of the pickling solution and reducing the discharge of waste liquid. |
