Description
Silicates, by their special function and producing negative charged colloid particles that easily attach to the metal surface, protect the surfaces against corrosion. They provide corrosion protection for various types of metal and are particularly useful in “zinc loss”. A mixture of silicates and polyphosphates is intended to improve the corrosion control performance. This special mixture with its specific function prevents the formation of scale layers in addition to corrosion control in the system. Proper polyphosphate compounds work better to deactivate calcium and magnesium carbonates and sulfates, and prevent the deposition of these compounds by creating stable complexes.
Calibration of Using Mitreh 951 Solution:
In order to prevent the formation scale and corrosion in closed circuit cooling tower systems, the amount of solution consumption varies depending on hardness of the inlet water.
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
