Tetra Sodium Salt of Amino Trimethylene Phosphonic Acid (ATMP•Na4) is an organic phosphonate-based water treatment agent with excellent chelating, dispersing, scale inhibition, and corrosion inhibition properties. It has a wide range of applications, primarily in water treatment, industrial production, and specific fields, as detailed below: 1. Water treatment field This is the primary application area for ATMP·Na₄, leveraging its h3 chelating ability toward metal ions and scale inhibition/corrosion inhibition properties: Industrial circulating cooling water systems: It effectively chelates metal ions such as calcium, magnesium, iron, and zinc in water, preventing them from combining with carbonate and sulfate ions to form scale (e.g., calcium carbonate and calcium sulfate scale). It also forms a protective film on metal surfaces, slowing down corrosion of equipment (e.g., pipes and heat exchangers) and extending the system's service life. It is particularly suitable for water wit...
