Product Description
The acidizing corrosion inhibitors produced by our company are formulated from a blend of aldehyde-ketone amine condensates, pyridinium quaternary ammonium salts, and other synergists. These inhibitors firmly adsorb onto metal surfaces, forming a dense, multi-layered, mesh-like protective film that blocks contact between the acid solution and the metal surface, thereby slowing down metal corrosion. Depending on the application temperature, the product is available in three models: 90°C, 120°C, and 140°C. Customers can select the appropriate acidizing corrosion inhibitor model based on their operational requirements.
Product Features
1. It adheres firmly to metal surfaces, forming a dense, multi-layered, mesh-like protective film.
2. It offers strong corrosion inhibition and effectively suppresses acid corrosion.
3. Customers can select the appropriate acid corrosion inhibitor model based on their application requirements.
4. It is available in three models—90°C, 120°C, and 140°C—depending on the application temperature.
Application
Used for acidification and to prevent acid corrosion.
