Development and Mechanism Study of Non-Phosphorus Scale and Corrosion Inhibitor to adding-acid Circulating Water Treatment Process
Non-phosphorus scale and corrosion inhibitor has been developed by compounding of HPMA、sulphonate polymer、BTA and zinc salt.Through analysis by SEM and model establishment,its mechanism of corrosion and scale inhibition had been studied.The results showed that a dense protective film was formed on the carbon steel surface,The law conformed to polynomials equation η=9×10-5c2+0.0039c+0.0237.The regular shape of calcium carbonate crystal and the integrity of crystal plane were destroyed.the lattice distortion caused scale inhibition.
