The corrosion resistance of bis(3-diylpropyl)aminoisopropyl alcohol ZR-50 in ship construction

Introduction

As an important tool for marine transportation, ships have been in a harsh marine environment for a long time and are facing serious corrosion problems. Corrosion not only affects the appearance of the ship, but also reduces its structural strength, shortens its service life, and even causes safety accidents. Therefore, the development and application of efficient corrosion-resistant materials and technologies is crucial for ship construction. As a new corrosion-resistant agent, bis(3-diylpropyl)aminoisopropyl alcohol ZR-50 has been widely used in ship construction in recent years.

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.
