CMC for papermaking |
 |
1、Product characteristics
In paper making, CMC can be used as the retention aid in pulping process. It can also be applied to the surface sizing, to enhance the glue water’s stability, increase the agglutinability between paper and glue, strengthen paper‘s compactness and anti-ink permeability, so as to improve paper’s printing quality. Using in coating as the excipient of the pigment etc, it is advantageous to pigment's dispersion and fluidity, and can enhance the paper’s glossiness, smoothness, optical property and printing adaptability. |
