The importance of polyurethane sponge deodorant to corrosion protection in ship construction: durable protection in marine environments

The importance of polyurethane sponge deodorant to corrosion protection in ship construction: durable protection in marine environment

Introduction

As an important tool for marine transportation and operations, ships have been exposed to harsh marine environments for a long time and face severe corrosion challenges. Factors such as high salinity, high humidity, strong ultraviolet radiation and microbial erosion in the marine environment will accelerate the corrosion process of ship materials. Therefore, how to effectively prevent ship corrosion and extend its service life has become a key issue in ship construction and maintenance. As a new anti-corrosion material, polyurethane sponge deodorant plays an increasingly important role in ship construction with its unique performance and advantages. This article will discuss in detail the importance of polyurethane sponge deodorant to corrosion in ship construction, especially the lasting protection effect of marine environments.

1. The impact of marine environment on ship corrosion

1.1 High salinity environment

The salt content in the marine environment is extremely high, especially the chloride ions in seawater are very corrosive. Chloride ions can penetrate the oxide film on the metal surface and react directly with the metal, resulting in rapid corrosion of the metal. When a ship is immersed in seawater for a long time, its metal structure will inevitably be eroded by chloride ions, thereby accelerating the corrosion process.

1.2 High humidity environment

The humidity in the marine environment is extremely high, especially in tropical and subtropical waters, where the humidity remains above 80% year-on-year. The high humidity environment provides sufficient moisture for metal corrosion, making it easy for the metal surface to form an electrolyte film, accelerating the occurrence of electrochemical corrosion. In addition, high humidity environments can easily lead to condensation on the metal surface, further aggravating corrosion.

1.3 Strong UV radiation

The intensity of ultraviolet radiation in the marine environment is much higher than that in the land environment, especially in the waters near the equator. Ultraviolet radiation can destroy the molecular structure of organic materials, causing the material to age and embrittle, thereby reducing its corrosion resistance. The coatings and sealing materials on the surface of the ship are prone to aging under strong ultraviolet radiation, losing their protective effect, and thus accelerating metal corrosion.

1.4 Microbial erosion

There are a large number of microorganisms in the marine environment, such as bacteria, fungi and algae. These microorganisms are able to form biofilms on the surface of ships, secrete acidic substances, and corrode metal surfaces. In addition, microorganisms can also decompose organic materials, destroy the anti-corrosion coating of ships, and further aggravate corrosion.
