Pan, Huaqiang published the artcileInfluencing factors and evaluation of CaCO3 modified with three coupling agents, Recommanded Product: Triphenyl(pyridin-1-ium-1-yl)borate, the publication is Wuhan Keji Daxue Xuebao (2013), 36(1), 64-68, database is CAplus.
KH101, KH151 and KH570 were used to modify the surface of CaCO3, resp., to improve the surface properties, and the optimum modification conditions were determined by analyzing the factors that influenced the activation grade of modified CaCO3. The modification effects of three coupling agents were compared by means of SEM anal. and settling volume test. The results show that, the optimum conditions for KH101 modification of CaCO3 are the reaction temperature at 80°C, the reaction time at 70 min, the coupling agent content at 3%, and the amount of cyclohexanone five times that of CaCO3, and the optimum conditions for KH570 and KH151 modification of CaCO3 are the reaction temperature at 70°C, the reaction time at 70 min, the coupling agent content at 3%, and the amount of cyclohexanone five times that of CaCO3. It is also found that modification with KH151 and KH570 is characterized by severe reunion phenomenon, while modification with KH101 can remarkably ameliorate the reunion phenomenon of CaCO3.
