Applications of Tannic acid
1. For feed additives and agricultural sterilizers. As an important trace element, copper can promote growth and increase feed utilization. Alkaline chloride bronze is more advantageous than copper sulfate in feed:
2. Insoluble in water, no moisture absorption, reduce the destruction of feed nutrients, and improve the quality of feed;
3. Use as a pharmaceutical intermediate.
4. Make the basic raw materials for other copper -salt products.
5. Reduce the copper content and soluble copper content in the feces, which is conducive to protecting the environment.
6, used as an absorbent of carbon dioxide in the air.
7, improve the feed conversion rate, good antibacterial effect, effectively improve animal anti -disease;
