| titleOfInvention | A kind of preparation method of particle size controllable cubic precipitated calcium carbonate |
| abstract | The invention discloses a preparation method of cubic precipitated calcium carbonate with controllable particle size. Add soluble alkali to the sodium solution, stir evenly, and prepare a sodium carbonate mixed solution; at room temperature, add the sodium carbonate mixed solution dropwise to the calcium chloride solution at a speed of 50-200 ml/min, and at a rate of 500-900 r/min The stirring speed is stirred evenly to obtain a reactant; and then the reactant is filtered, washed, separated and dried to obtain a cubic precipitated calcium carbonate. The method of the invention uses sodium carbonate and calcium chloride as the initial raw materials for the reaction, uses the alkyl phosphate as the surfactant, and realizes the control of the particle size of the calcium carbonate by controlling the pH of the system in the reaction process. The invention has simple operation, mild reaction conditions and low price of experimental raw materials, and provides a direction for particle size control of industrially produced precipitated calcium carbonate. |
