ACTION OF CH-2, CH-3 INHIBITORS

Anodic passivation, or the formation of a protective layer:
A corrosion inhibitor acts through a mechanism called anodic passivation. As a result of the electrochemical process, the inhibitors in the protective fluid water are directed to the anode and cathode and are chemically absorbed on the surface. The resulting layer forms a barrier that effectively isolates the anode from the circulating water and from contact with the cathode. This slows down the corrosion rate to a small level, usually 100 or 1000 times less compared to corrosion in water without protective fluid.
The passive layer is subject to continuous disruption and reconstruction and its presence depends on the continuous presence of an inhibitor in the water to repair the passive layer. If the inhibitor is missing, the corrosion protection is also interrupted, and in a very short time. Usually, the most anodic part of the component is attacked, for example a stressed weld in a radiator or a crack. The corrosion rate across the surface may be very low, but can be very high at a particular point, causing perforation of the metal at that point.
Adjusting the pH level to inhibit corrosion of iron and steel.
The acidic or basic reaction (pH) of the plumbing water plays a significant role in the corrosion of metals. For example, iron and steel corrode quickly in an acidic environment, but slowly in a basic environment. The rate of corrosion is influenced by the type of corrosion product formed under different pH conditions. In an alkaline environment, iron and steel, corrode to form magnetite Fe304, which forms a selective layer on the metal surface that slows the corrosion rate. Steel is the main material to be protected. The inhibitor is designed to change (buffer) the pH to neutral or slightly alkaline, which promotes slowing of the corrosion rate. Buffering ensures that both acidic and basic additives can be tolerated without changing the pH.
Adjusting pH levels to inhibit corrosion of aluminium.
Aluminium is an active metal that can be used for technical products such as condensing boilers, aluminium radiators, due to the completely insoluble oxide film that forms immediately on the metal surface on contact with air or in a neutral aqueous environment. In contrast, extreme conditions of acidity or alkalinity dissolve the protective oxide film and cause rapid corrosion. An inhibitor supplements the natural corrosion protection produced by oxide coatings by incorporating the oxides into the inhibitory coating and by adjusting the pH. The action of the inhibitor effectively prevents the phenomenon of overgrowing of copper pipes in central heating installations, thus the installation is maintained in high efficiency for many years.
Effectiveness of anti-sedimentation action
The formula of the inhibitor ensures high effectiveness in preventing boiler scale and deposits. This eliminates many negative processes occurring in unprotected central heating installations. The action of the preparations is specifically targeted at boilers and exchangers, where the greatest amount of scale is generated. Scale deposits in boilers may lead to their noisy operation, low efficiency or even breakdown, such as exchanger cracking.
Prevention of biological contamination.
Bacterial, yeast or algae infections can be caused by organisms that enter the system with the water, remain on the residuals after commissioning or enter from the atmosphere, e.g. in open expansion vessels. Such infections can cause the formation of methane gas in radiators (explodes with a blue flame), not to be confused with the release of hydrogen gas, which is the result of corrosion. Hydrogen sulphide (smell of rotten egg) can also happen, its presence is related to the presence of sulphate reducing bacteria that cause corrosion.

Additional information.
The product can be injected via a collection vessel, poured directly into the system at any point, or injected using an injector (as used in gardening) or see description of other ways of injecting. The preparation should be protected from freezing temperatures. It should not be mixed with other preparations (except anti-freeze preparations). The product is not toxic, but as with other preparations, it should be used with caution. In household and industrial installations it is recommended to check periodically the inhibitor concentration in the installation using the "Tester of inhibitor concentration" ATTENTION - AIR CONDENSED HEATERS (air, oxygen, hydrogen, methane, etc.). This is most often a sign of corrosive processes in the central heating system. Only inhibitors prevent this phenomenon. HEATER DEFILING does not eliminate the causes but only the effects. An inhibitor is a water conditioner for central heating systems.
