Description:
Generally speaking, chitin mainly refers to chitosan, which is also called chitin, deacetylated chitin, deacetylated chitin, soluble chitin and soluble chitin. Almost insoluble in water, but soluble in organic acids such as formic acid, acetic acid, benzoic acid and naphthenic acid and dilute inorganic acids. The industrial product is a white or off-white translucent flaky solid with a slight pearl luster. Odorless, non-toxic and easily degradable, it is a rare natural cationic polyelectrolyte.

Application Field:
1.Sewage treatment: Chitosan can treat suspended substances in sewage, adsorb certain heavy metal ions, etc., reduce BOD and COD of sewage, and chitosan can also be used in surface water treatment.
2.Petroleum Auxiliary: According to the characteristics of chitosan's macromolecule properties and amino positive charge, chitosan can also be used in the fields of petroleum exploitation and shale gas exploitation assistants.
3.Paper making: Special types of chitosan can be used as sizing agent, reinforcing agent, retention aid, etc. in paper making to increase paper strength and recover lost pulp.
4.Agriculture: Chitosan can be used in seed soaking, coating agent, foliar spray fertilizer, bacteriostatic agent, soil conditioner, feed additive, fruit and vegetable preservative, etc.
5.Chitosan is also widely used in other fields.
