|Corrosion inhibitor||Chemical which protects metals by: (a) passivating the metal by the promotion of a thin metal oxide film (anodic inhibitors); or (b) physically forming a thin barrier film by controlled deposition (cathodic inhibitors).|
Chemicals used to control scale. They function by holding up the precipitation process and/or distorting the crystal shape, thus preventing the build-up of a hard adherent scale.
Bio-dispersants are used to loose microbial deposits, which can then be killed by biocides or flushed away easily. They also expose new layers of microbial slime or algae to the attack of biocides. Used as an effective preventive measure, Bio-dispersants prevent micro-organisms from attaching to equipment and / or pipework surfaces to form deposits. Bio-dispersants can greatly enhance performance of biocide.
|Rust Remover||Rust Remover can detach rust materials from the system and disperse them in cooling water which can be disposed. It increases the effectiveness of both corrosion inhibitor and biocide can protect the clean/exposed metal surface from corrosion.|
Passivation is a treatment process that forms a thin protective layer. This layer reduces chemical activity with air, water or other material contacting the surface. The passivation process varies depending on the type of material to be protected and the substances with which it contacts.
