The main components of scale inhibitors can vary according to different types and application fields. The following are some common components of scale inhibitors:
Phosphates: such as sodium phosphate (Na3PO4), sodium dihydrogen phosphate (NaH2PO4), etc. Phosphate substances are commonly used to prevent the deposition of inorganic salts such as limestone and calcium sulfate in water.
Corrosion inhibitors: Common corrosion inhibitors include organic phosphates (such as ATMP, HEDP), polycarboxylates (such as PCA), condensation acids, etc. These compounds can form complexes with metal ions, inhibit electrochemical reactions of metals, and thus prevent corrosion and deposition on metal surfaces.
Surfactants: such as sodium dodecylbenzene sulfonate (SDBS), sodium dodecyl sulfate (SDS), etc. Surfactants have the effect of reducing liquid surface tension and improving the wettability and permeability of cleaning agents.
Chelating agents: such as nitroso dicarboxylate (NTA), ethylenediaminetetraacetic acid (EDTA), etc. Chelating agents can form stable complexes with metal ions, inhibiting metal deposition and scaling.
Polymer: such as polyacrylamide (PAM), sodium polyacrylate (PAA), etc. Polymers can prevent particle deposition and scaling through adsorption and encapsulation.
These components may be combined and adjusted according to different usage purposes and application fields. When using scale inhibitors, appropriate products should be selected based on the actual situation and strictly follow the instructions and recommendations provided by the manufacturer for operation.
