Effect Mechanism of Scale and Corrosion Inhibitor

Organic phosphonate scale inhibition mechanism: CaCO3 grain adsorption of organic phosphonate molecules, the disruption of the order of the lattice, not easy to form CaCO3 large particles of crystallization. As a result of the surface phenomenon, small grains CaCO3 solubility is large, and thus played a scale effect. At the same time, CaCO3 adsorbed organic phosphonates, CaCO3 lattice internal large internal stress generated by the distortion, resulting in some of the larger non-crystalline particles, these non-crystalline particles are not easy to scale, easy to form water residue and water Scattered or washed away.

     Polycarboxylic acid dissolved in water after ionization, resulting in negatively charged molecular chains such as:

     -COOH = -COO - + H +

     These negatively charged molecular chains form a water-soluble complex with Ca2 + to stabilize the calcium ions, thereby increasing the solubility of the fouling compound and acting as a scale inhibitor.
