Boiler oxygen is a chemical additive used to prevent oxygen corrosion in the boiler system. Its main ingredients usually include the following:
Sulfate: Common sulfate includes sodium sulfate (NA2SO3), sodium sulfate (NaHSO3), etc. Sulfate can react with the oxygen dissolved in the water to generate sulfate, thereby playing the role of oxygen dehuminating.
Chelators: Chelators can form complexes with metal ions in boiler water, reducing the catalytic effect of metal ions on oxygen, and reducing the risk of oxygen corrosion. Common chelated agents include EDTA (ethyleine tetharium) and cypressic acid.
Alkaline substances: alkaline substances such as sodium bicarbonate (NAHCO3) or sodium hydroxide (NAOH) can adjust the pH value of boiler water to keep it within a high alkaline range, thereby reducing the possibility of oxygen corrosion.
Correspondent: The corrosion agent is a chemical that can form a protective film that can cover the metal surface and reduce the direct contact of the metal by oxygen. The corrosion can be an organic compound, such as organic phosphorus compounds and organic amine compounds.
It should be noted that different types and brands of boilers may have different formulas and ingredients. Before using a boiler oxygen, please read the product description and operation guide carefully, and use it correctly according to relevant suggestions. At the same time, follow the safety operation regulations, ensure appropriate proportion and use methods, and suggestions from consulting professionals.
