he classification of anti-corrosive.corrosion inhibitor according to chemical component
It can be divided into inorganic inhibitor, organic inhibitor and polymer inhibitor
①inorganic (corrosion) inhibitor
Inorganic corrosion inhibitors mainly include chromate, nitrite, silicate, molybdate, tungstate, polyphosphate, zinc salt and so on.
②organic corrosion inhibitor
Organic corrosion inhibitors mainly include some heterocyclic compounds including phosphonic acid (salt), phosphonic acid (carboxylic acid), ionic benzothiazole, benzotriazole and lignin sulfonate.
③Polymer corrosion inhibitors
Polymer corrosion inhibitors mainly include polyethylene, POCA, polyaspartic acid and some of the low polymer polymer chemistry.
