Some aromatic azoles compounds are chemically adsorbed on the metal surface and thus prevent corrosion on the surfaces. It means a metal ion is replaced by an ion in the azole and forms a joint bond. Then the coordination joint bonding creates between the metal and the pair electrons of azole compound atoms. The complex insoluble mixture form a thin film that reinforces ordinary metal oxide films. The film was formed protects metal against oxidizing agents and as a result the metal is protected against corrosion.
Calibration of Using Mitreh 753 Solution:
The amount of solution consumption is different in order to prevent of corrosion in open circuit cooling tower systems, actually the dosage consumed varies depending on the water conditions and some characteristics of the water consumed. Consult your company’s technical experts for accurate dose calculation.
In the first few weeks of use, this inhibitor should be used at a rate of two to three times the normal level to produce the best film on the entire metal surface (primary improvement).
