Study on White Mud Calcium Carbonate’s Crystallization Character in Causticization Process of Straw Pulping

Abstract:

Through improving the traditional causticization process, such as needle-like White Mud and rice-like White Mud are obtained by adding auxiliary agent and controlling the causticizing reaction conditions. Results show that the uniform needle-like White Mud and rice-like White Mud can be better applied to paper filling, especially the needle-like White Mud, which demonstrates higher opacity and higher whiteness than commercial PCC, while has the same influence on strength and other properties with commercial PCC.
