Product application:

1. in the field of papermaking, cationic chitosan is widely used in various papermaking auxiliaries with the following excellent characteristics :

(1) linear water-soluble polymer with large relative molecular weight, strong film-forming ability and sufficient adhesion strength to the fiber ;

(2) good compatibility with cellulose without destroying the hydrogen bond between cellulose molecules ;

(3) functional groups can fully contact the paper fiber and can firmly bind it through ionic bonds or hydrogen bonds; and

(4) nontoxic, biodegradable natural products.

2. in the field of tobacco, chitosan is a good performance of tobacco thin film glue, and has the characteristics of improving taste, burning non-toxic and no odour.

3. in the field of environmental protection: for sewage treatment, protein recovery, water purification and so on.
