The above data are based on standard working conditions. Actual results vary depending on device conditions. It is recommended to apply for sample evaluation.
Imidazoline compounds are adsorbed on the metal surface through polar head groups, forming a hydrophobic protective film to block direct contact between corrosive media (HCl, H₂S, CO₂) and carbon steel.
The nitrogen-containing heterocycle in the molecule forms a coordination bond with iron atoms through lone pairs of electrons, and is firmly adsorbed on the metal surface. The thickness of the single layer is about 2–5 nm.
The hydrophobic alkyl chains are arranged outward, effectively blocking water molecules, Cl⁻, H⁺ and other corrosive ions, and reducing the rate of anode dissolution and cathode reduction reactions.
It not only inhibits the dissolution of anode iron, but also inhibits the precipitation of hydrogen gas at the cathode. It is a mixed corrosion inhibitor and can achieve high corrosion inhibition efficiency at a low dosage.
Continuous or intermittent injection through metering pumps maintains the integrity of the metal surface film and copes with film loss caused by flow rate changes and medium erosion.
Selection tips:How to select imidazoline Mainly depends on the phase state and temperature of the medium, judge first The difference between oil soluble and water soluble (The water phase is injected with washing water at the top of the tower, and the oil phase is injected with circulating oil). In addition, imidazoline and its Imidazoline derivatives also extends to Machining corrosion inhibitor, metal cutting fluid and other metal processing scenes.
