ATMP (amino trimethylene phosphonic acid) is a commonly used corrosion and scale inhibitor. As an additive, ATMP plays the following roles in water treatment and industrial production:
Corrosion inhibitor: ATMP can form a protective phosphate calcium oxide film covering the metal surface, preventing the reaction between the metal and dissolved oxygen, metal ions, etc. in water, and reducing the corrosion rate of the metal.
Scale inhibitor: ATMP can inhibit the scaling of hard water salts (such as calcium carbonate and barium carbonate) in water, and prevent them from depositing on pipelines, equipment surfaces, and heat exchangers by forming insoluble complexes or precipitates with the salts.
Chelating agent: ATMP has the ability to eliminate metal ions in water, mainly having strong chelating effects on divalent metal ions such as calcium and magnesium. By forming stable complexes with these metal ions, ATMP can effectively control the content of metal ions in water and reduce the adverse effects of metal ions on water quality and equipment.
Dispersant: ATMP can also serve as a dispersant to evenly disperse suspended particles in water and prevent particle deposition or aggregation.
In summary, ATMP plays an important role as an additive in water treatment and industrial production. It can inhibit metal corrosion, scale, chelate metal ions, and disperse particles, thereby protecting equipment, maintaining water quality stability, and extending the service life of the equipment.
