Production method Of Paper Grade Indirect Zinc Oxide:
With the rapid development of industrial and agricultural economy, the demand for special paper has been diversified, and it has put forward higher requirements. Zinc oxide in the paper industry is mainly used in anti-water, anti-bacterial, anti-static, anti-aging and flavoring, fire-retardant, color paper and other functions of the development of nano-Zinc oxide gradually be applied as a paper additive.
Application Of Paper Grade Indirect Zinc Oxide:
The zinc oxide for papermaking, it can be used in the zinc oxide printing plate, zinc oxide paper production.
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
