| titleOfInvention | A kind of preparation method of nano flake calcium sulfate |
| abstract | The invention discloses a preparation method of nano-flaky calcium sulfate. The method comprises the following steps: taking glycerol and ethylene glycol and mixing them uniformly at 60-80°C, then adding a calcium ion complexing agent, and continuing to stir until The particles are dissolved, and calcium sulfate dihydrate sample is added for reaction. After the reaction, solid-liquid separation is carried out while hot, and the obtained solid is dried to obtain nano-flaky calcium sulfate. The present invention can use calcium sulfate dihydrate or phosphogypsum containing calcium sulfate dihydrate, and flue gas desulfurization gypsum to add calcium ion complexing agent to prepare nano-flaky calcium sulfate. The advantages of comprehensive utilization value; the nano-flaky calcium sulfate of the present invention has the characteristics that each dimension can reach the nanometer level, and it is of great significance to promote the high value-added resource utilization of phosphogypsum. |
