| 摘要 |
This invention provides a corrosion inhibitor for iron-based metals including a solution of a polysaccharide biopolymer, or a precursor or derivative thereof, in a solvent. The polysaccharide biopolymer is preferably chitosan, which is obtained from deacetylated chitin. This invention further provides a method of inhibiting corrosion of iron-based metals and a method of manufacturing a corrosion inhibitor including the steps of providing chitin; at least partially deacetylating the chitin to obtain chitosan; and dissolving the chitosan in a solvent. The corrosion inhibitor according to the invention provides a relatively cheap and environmentally friendly and non-toxic corrosion inhibitor suitable for protecting iron-based metals against corrosion damage by aqueous solutions, or to minimise such problems to an appreciable extent. |
