| titleOfInvention | A kind of preparation method of cubic nanometer calcium carbonate |
| abstract | The present invention relates to a kind of preparation method of cubic nanometer calcium carbonate, the method comprises the following steps: (1) the lime milk suspension is sieved to remove impurities, and the refined calcium hydroxide suspension is prepared; (2) the refined calcium hydroxide is The suspension is added to the stirring reaction kettle, stirring is started, and then the mixed gas containing carbon dioxide is introduced to carry out the carbonization reaction; (3) 3-10 minutes after the carbonization reaction starts, the cage-like crystal form control agent is added; (4) Use a pH meter to monitor the carbonization reaction process , when the pH value of the suspension is 6.5~7, the carbonization reaction ends, and a reaction solution is obtained; the reaction solution is aged, centrifuged, washed and dried to obtain a nano-calcium carbonate product. The invention can improve the nucleation and growth rate of calcium carbonate, and realize the ultrafineness and cube formation of calcium carbonate. |
