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.

The unique application of polyurethane sponge aldehyde removal agent in the preservation of art works: the combination of cultural heritage protection and modern technology

The unique application of polyurethane sponge aldehyde removal agent in the preservation of art works: the combination of cultural heritage protection and modern technology

Introduction

Cultural heritage is a witness to human history and civilization, carrying the wisdom and emotions of countless generations. However, over time, these precious art and cultural relics face threats from various natural and man-made factors, especially harmful gases in the environment, such as formaldehyde and benzene, which are not only harmful to human health, but also cause irreversible damage to the materials of the artwork. How to effectively protect these cultural heritages has become an important topic in the field of modern cultural relics protection.

In recent years, polyurethane sponge aldehyde removal agent, as a new environmentally friendly material, has gradually emerged in the field of cultural heritage protection. Its unique physicochemical properties make it an ideal choice for removing harmful gases and purifying the environment. This article will deeply explore the unique application of polyurethane sponge aldehyde removal agent in the preservation of art works, analyze its technical principles, product parameters and practical application cases, and show the perfect combination of cultural heritage protection and modern technology.

Chapter 1: Challenges and Needs for Cultural Heritage Protection

1.1 The fragility of cultural heritage

Cultural heritage, especially organic artworks such as paper, wood, textiles, etc., are highly susceptible to the erosion of harmful gases in the environment. VOCs such as formaldehyde will not only accelerate the aging of materials, but also cause pigment fading, paper brittleness, and wood cracking. In addition, these harmful gases may also cause the growth of microorganisms, further aggravate the damage to cultural relics.

1.2 Limitations of traditional protection methods

Traditional methods of cultural relics protection mainly include physical isolation, chemical treatment and temperature and humidity control. However, these methods often have certain limitations. For example, physical isolation cannot completely isolate harmful gases in the air; chemical treatment may cause secondary damage to the cultural relics themselves; although temperature and humidity control is effective, it is expensive and difficult to cover all the time.

1.3 Intervention of modern technology

With the advancement of science and technology, new materials and technologies have gradually been introduced into the field of cultural heritage protection. As a highly efficient and environmentally friendly aldehyde removal material, polyurethane sponge aldehyde removal agent has become a new favorite in the field of cultural relics protection with its excellent adsorption performance and stability.

Chapter 2: Technical principles of polyurethane sponge aldehyde removal agent

2.1 Structural characteristics of polyurethane sponge

Polyurethane sponge is a porous material with rich three-dimensional mesh structure inside, large surface area and high porosity. This structure enables it to effectively adsorb harmful gases in the air, especially VOCs such as formaldehyde.

2.2 Aldehyde removal mechanism

Polyurethane sponge aldehyde removal agent removes harmful gases through physical adsorption and chemical adsorption:

Physical Adsorption: Relying on the pore structure on the surface of the material, gas molecules are captured and fixed in the pores.

Chemical adsorption: The active ingredient supported on the surface of the material (such as amino compounds) undergoes chemical reaction with formaldehyde and converts it into harmless substances.

2.3 Technical Advantages

Compared with traditional aldehyde removal materials, polyurethane sponge aldehyde removal agent has the following advantages:

High efficiency: Fast adsorption speed and high aldehyde removal efficiency.

Environmentality: The materials are non-toxic and harmless, and will not cause secondary pollution to cultural relics and the environment.

Stability: Stable performance under normal temperature and pressure, with a long service life.
