Method for obtaining precipitated calcium carbonate particles of nanometric scale structure

本发明涉及通过石灰乳的碳酸饱和制备纳米级构造的沉淀碳酸钙颗粒的方法，碳酸饱和在结晶调节剂的存在下进行，其中该结晶调节剂选自：聚天冬氨酸、二辛基磺基琥珀酸钠、分子量为500-15,000的聚丙烯酸和柠檬酸。当结晶调节剂是柠檬酸时，其在石灰乳中的浓度为5-15％。 Process for the production of precipitated calcium carbonate particles, structured at the nanoscale, by carbonation of milk of lime in the presence of a crystallization...

Zusammenfassung:	本发明涉及通过石灰乳的碳酸饱和制备纳米级构造的沉淀碳酸钙颗粒的方法，碳酸饱和在结晶调节剂的存在下进行，其中该结晶调节剂选自：聚天冬氨酸、二辛基磺基琥珀酸钠、分子量为500-15,000的聚丙烯酸和柠檬酸。当结晶调节剂是柠檬酸时，其在石灰乳中的浓度为5-15％。 Process for the production of precipitated calcium carbonate particles, structured at the nanoscale, by carbonation of milk of lime in the presence of a crystallization controller selected from the following list: polyaspartic acid, dioctyl sodium sulphosuccinate, polyacrylic acid, the molecular weight of which is between 500 and 15 000, and citric acid. When the crystallization controller is citric acid, its concentration in the milk of lime is between 5 and 15%.
