| titleOfInvention | A kind of preparation method of nano combined superfine heavy calcium carbonate |
| abstract | The present invention is a kind of preparation method of nano combined superfine heavy calcium carbonate, solves nanometer calcium carbonate applied to other field oil absorption height, water imbibition height, the problems such as flowing and squeeze out difference.Present invention process, using series connection supergravity reactor advantage, prepares nano combined ultrafine heavy calcium using ultra-fine wet lapping coarse whiting as base core, while using supercritical CO 2 Fluid low temperature drying guarantees that the nanoparticle of superfine heavy calcium carbonate adsorption is not reunited coalescence.Nano combined ultrafine heavy calcium partial size made from the method for the present invention is small, BET is big, viscosity and thixotroping are good, reunites less, even particle size distribution, easily dispersion, and hydrophilic oil absorption is small in, flowing and extrudability good. |
