Description
Technical field
The present invention relates to a kind of New Building Materials and method thereof of utilizing industrial residue preparation, especially a kind of high reactivity micro mist of producing with waste sludge from paper mill or cement and preparation method thereof.
Technical background
China is pulping and paper-making big country, according to statistics in 2008, and annual 1000 ten thousand tons of the white claies that produce of national papermaking; These white claies have only few part to obtain utilizing at present, and major part all is outdoor stacking, not only takies not a large amount of soils; Contaminate environment consumes great amount of manpower and material resources, financial resources are managed, and wasted useful resources a large amount of in the white clay; If can rationally utilize this type white clay; Not only solve white clay outlet and problem of environmental pollution, and can reduce enterprise cost significantly, improved enterprise competitiveness.
Paper white sludge derives from the recovery stage between the alkali recovery vehicle; Black liquor of pulp making is through extracting evaporation concentration; Obtain melts in the alkali recovery furnace roasting, the water-soluble green liquor that is adds slaked lime then and carries out the white depositions that causticizing reaction obtains in the green liquor and be the causticization white clay.Causticization white clay staple is following:
| Composition | CaO | MgO | Fe 2O 3 | Al 2O 3 | SiO 2 | Acid non-soluble substance | Loss on ignition |
| Ratio | 44.2~52.1 | 0.56~1.81 | 0.15~4.2 | 0.44~1.4 | 3.4~16.8 | 5.7~8.4 | 31.49~44.62 |
The WWT waste residue that papermaking produces comprises: a large amount of throw outs when one-level is handled in the deposition pool, and its staple is white clay and macrofiber; The second-stage treatment waste residue that has added chemical reagent such as flocculation agent, Tai-Ace S 150, urea, tsp, its composition are complicated.
Flyash is the thin ash (generally being meant the thin ash that collect the coal-burning power plant from flue gas) in the flue gas that produces of coal combustion, and the chemical ingredients of general flyash mainly is: SiO
