Use:
The zinc oxide for papermaking, it can be used in the zinc oxide printing plate, zinc oxide paper production.
Characteristic and function:
1. It is small granule, easy to disperse. It can make printing plate homogenized, fine and smooth
2. Zinc oxide is luster pure white and tinting strength. It can increase the paper white degree, also has advantageous for the colored paper coloration.
