Corrosion inhibitor pbtc is a chemical substance used to prevent metal corrosion, which can be divided into the following main categories:
Adsorption type corrosion inhibitor: This type of corrosion inhibitor forms an adsorption film on the metal surface, preventing oxygen, water, and other corrosive media from coming into contact with the metal surface. Common adsorption type corrosion inhibitors include organic amines, ketone acids, esters, etc.
Corrosion inhibitor complex: This type of corrosion inhibitor inhibits the participation of metal ions in corrosion reactions by forming a complex with metal ions. Common corrosion inhibitor complexes include organic acids, organic amines, acetals, etc.
Scale and corrosion inhibitors: These types of corrosion inhibitors prevent contact with scale, size changes, and corrosive media by forming a covering film on the metal surface. Common scale and corrosion inhibitors include phosphates, polymers, inorganic salts, etc.
Oxidation corrosion inhibitor: This type of corrosion inhibitor forms a layer of oxide film on the metal surface, reducing the contact between the metal and the corrosive medium. Common oxidation corrosion inhibitors include iron oxide, alumina, chromium oxide, etc.
Passivation agent: This type of corrosion inhibitor forms a dense passivation film on the metal surface to prevent further corrosion reactions. Common passivating agents include chromates, nitrates, borates, etc.
It is necessary to select suitable corrosion inhibitors based on the actual situation and use them correctly according to the operating guidelines. In addition, it is very important to understand the properties of chemical substances and the prescribed safety operations, ensuring that relevant safety measures and environmental regulations are followed when using corrosion inhibitors.
