| Abstract: | Using the activating efficiency as main test method, the surface modification of nanometer CaCO3 by fatty acid salt is studied. The results show that fatty acid sodium can gain a higher efficiency instead of the traditional modifying agent fatty acid. TEM and FTIR are also employed to characterize the surface of the CaCO3 particles. A finer process condition is obtained (modifying agent dosage 3%～4%、temperature 95～100 ℃and reacting time about 30 minutes.) |
