The combination of phosphates and specific polymeric phosphates at different pH ranges effectively prevents the formation of different scales on the surfaces. Polymers with organic matter in this compound, are able to prevent the formation of precipitates by the formation of complexes, and can also protect the metals against corrosion by forming protective layers.
Combining polymeric compounds with phosphates significantly inhibits the formation of calcium and magnesium carbonates and sulfates, resulting in efficient heat transfer on the surfaces and no sub-scale corrosion problems.
Another advantages of Mitreh 1138 solution is its 98% anti-corrosion performance. The rapid formation of resistant film over a wide range of temperatures and pH (due to the presence of active ions and special anti-corrosion compounds) is another important cause of the high anti-corrosion performance of this solution.
Calibration of Using Mitreh 1138 Solution:
In order to prevent the scale formation and corrosion in exchangers the dosage is different, depending on the hardness of the feed water and the type of boiler alloy.
The appropriate dosage shall be informed by the relevant technical experts and facility engineers, and if there is any uncertainty or need for advice, get advice from the expert of technical office of Abrizan Company.
To calculate more accurately, consider the following:
- Sample analysis of system feed water
- Ensuring that the system is clean (in terms of scale and other contaminants)
- The amount of water circulating and the volume of water consumed (make-up)
- Complete system monitoring and field inspection of various parts of the circuit in terms of corrosion
