2. Anti-corrosion mechanism of bis(3-diylpropyl)aminoisopropyl alcohol ZR-50

2.1 Basic principles of corrosion

Ship mainly faces the following types of corrosion in marine environments:

Electrochemical corrosion: Since seawater is a good electrolyte, microcells will form on the metal surface, causing metal ions to dissolve.
Microbial Corrosion: Microorganisms in the ocean will form biofilms on the metal surface, accelerating the corrosion process.
Stress Corrosion: The ship is subjected to various stresses during its navigation, resulting in cracks on the metal surface and accelerated corrosion.

2.2 Corrosion resistance mechanism of ZR-50

ZR-50 plays a corrosion-resistant role through the following mechanisms:

Adhesion: The amine groups and hydroxy groups in ZR-50 molecules can be adsorbed on the metal surface, forming a protective film to prevent the corrosive medium from contacting the metal.
Corrosion Inhibitory: ZR-50 can form stable complexes with metal ions, reducing the dissolution rate of metals.
Inhibition of microbial growth: ZR-50 has certain antibacterial properties, can inhibit the growth of marine microorganisms on the metal surface and reduce microbial corrosion.
