Dosage Determination of Aluminate Coupling Agent Modifying Nano-Calcium Carbonate
After the surface of nano-CaCO3 was modified with aluminate coupling agent by wet-modification, aluminate coupling agent dosage of 2.5% is the best through activation grade and oil-absorbed value. Then the modifier amount can be regarded as the best dosage that is confirmed by settlement volume in liquid paraffin and the modified mechanism is given in the end of the paper.
