Boiler deoxidizer is a chemical agent used in boiler water treatment to remove oxygen from water and prevent metal corrosion in boilers. The following are the possible chemical components of a common boiler deoxidizer:
Sulfite: Sulfate is a common boiler deoxidizer, such as sodium sulfite (Na2SO3) or sodium bisulfite (NaHSO3). They can react with oxygen dissolved in water to generate sulfur dioxide (SO2), thereby removing oxygen.
High molecular weight polymer: The deoxidizer may contain some high molecular weight polymers, such as polyacrylamide. These polymers can form a protective film in water, reducing the contact between oxygen and metals, and playing a role in alleviating corrosion.
Corrosion inhibitors: Boiler deoxidizers may also contain some corrosion inhibitors, such as organic amines or phosphates. These corrosion inhibitors can form a protective film on the metal surface, reducing the degree of metal corrosion.
PH regulator: In order to regulate the pH value of boiler water, deoxidizers may contain some pH regulators, such as alkaline substances (such as sodium hydroxide) or acidic substances (such as hydrochloric acid). A suitable pH value can help reduce metal corrosion.
It should be noted that different types of boiler deoxidizers may use different chemical compositions and formulas, and the specific composition may vary depending on the product manufacturer and application requirements. When using boiler deoxidizers, please follow the relevant instructions and safety operating procedures, and ensure that the correct dosage and method are used to ensure the normal operation and extended service life of the boiler.
