| titleOfInvention | Method for preparing industrial ultra-fine activated calcium carbonate from carbide slag |
| abstract | The invention discloses a method for preparing industrial ultra-fine activated calcium carbonate from a carbide slag, and particularly relates to preparation of employing O/W-type microemulsion. The technology disclosed by the invention comprises the steps of extracting calcium in the carbide slag by saturated ammonium chloride solution, and separating undissolved impurities to filter and obtain calcium chloride solution; reacting fatty acid and alkyl alcohol with sodium hydroxide solution, and adding petroleum ether to form microemulsion; fining microemulsion particles by ultrasound, slowly dripping the obtained calcium chloride solution under an agitation condition, dripping carbonate or bicarbonate solution after dripping, thereby respectively obtaining an upper layer of oil phase, a middle layer of opaque oil phase containing calcium carbonate sediment, and a lower layer of water phase after reaction and delivery are finished; and centrifugally separating, washing and drying the middle layer to obtain industrial ultra-fine activated calcium carbonate, wherein the oil phase and the water phase can be recovered to apply mechanically. By adopting the method, the processing problem of the carbide slag can be well solved; the obtained oil phase and water phase can be recycled; the cost is saved; the prepared light calcium carbonate surface is coated with a layer of fatty acid; the dispersibility is good; the problem that the product is easily gathered is solved; and the method has economical, social and environment-friendly concepts. |
