The importance of delayed amine hard bubble catalysts to corrosion protection in ship construction: durable protection in marine environments

Introduction

As the main tool for marine transportation, ships have been exposed to harsh marine environments for a long time and face serious corrosion problems. Corrosion not only affects the appearance of the ship, but also weakens its structural strength, shortens its service life, and even causes safety accidents. Therefore, corrosion protection technology in ship construction is crucial. As an efficient anti-corrosion material, the delayed amine hard bubble catalyst plays an important role in ship construction. This article will discuss in detail the importance of delayed amine hard bubble catalysts to corrosion protection in ship construction, especially the durable protection in marine environments.

1. The impact of marine environment on ship corrosion

1.1 Corrosion factors of marine environment

The corrosion of marine environment on ships mainly comes from the following aspects:

Salt spray: Salt in seawater forms a salt spray in the air, attaching to the surface of the ship, accelerating the corrosion of metal.
Humidity: The marine environment is high in humidity, and water films are easily formed on the metal surface, which promotes electrochemical corrosion.
Temperature: The temperature of the ocean ambient changes greatly, high temperature accelerates corrosion reaction, and low temperatures may lead to metal embrittlement.
Microorganisms: Microorganisms in the ocean, such as sulfate reducing bacteria, will accelerate the corrosion of metals.

1.2 Effects of corrosion on ships

The impact of corrosion on ships is mainly reflected in the following aspects:

Decreased structural strength: Corrosion will weaken the structural materials of the ship and reduce its load-bearing capacity.
Damaged appearance: Corrosion will cause rust spots, peeling and other phenomena on the surface of the ship, affecting the beauty.
Increased maintenance costs: Corrosion requires regular maintenance and repair, increasing the operating costs of the ship.
Safety Hazards: Severe corrosion may cause the ship’s structure to fail and cause safety accidents.
