Anti-biological adhesion technology of SBR diving composite fabrics keeps surface clean

Abstract

SBR (Styrene-Butadiene Rubber) diving composite fabrics are widely used in marine engineering, underwater operations and sports equipment due to their excellent physical properties and chemical stability. However, when soaked in water for a long time, its surface is easily adhered to microorganisms, algae and other organisms, affecting the service life and function of the material. To solve this problem, scientists have developed a variety of anti-biological adhesion technologies designed to extend the use cycle of SBR composite fabrics and keep their surfaces clean. This article will discuss in detail the anti-biological adhesion technology of SBR diving composite fabrics, and analyze them in combination with famous foreign literature, while providing specific product parameters and application examples.

1. Introduction

With the rapid development of the marine economy, the demand for high-performance materials in marine engineering, underwater operations and water sports is increasing. As an important functional material, SBR composite fabric has excellent wear resistance, corrosion resistance and flexibility, and is widely used in products such as diving suits and underwater equipment protective covers. However, SBR materials will face serious biological adhesion problems during long-term use in water, which not only affects the appearance of the material, but also leads to degradation of material properties and even causes structural failure. Therefore, researching and developing effective anti-bioadhesion technologies is crucial to improving the performance and service life of SBR composite fabrics.

2. Basic characteristics of SBR composite fabric

SBR composite fabric is a multi-layer structural material composed of SBR rubber and fabric substrate through a special process. Its main features are as follows:

1. High elasticity: SBR rubber imparts good elasticity and resilience to the material, and can adapt to complex underwater environments.
2. Abrasion Resistance: Composite fabrics have high wear resistance and are suitable for frequent friction and collision occasions.
3. Corrosion resistance: SBR materials have strong resistance to corrosive media such as seawater and salt spray.
4. Flexibility: The material is soft and easy to process and is suitable for making underwater equipment of all shapes.

3. Biological attachment phenomenon and its hazards

Bio attachment refers to the growth and reproduction process of organisms such as microorganisms, algae, shellfish, etc. on the solid surface. In marine environments, SBR composite fabrics are exposed to water for a long time and are prone to becoming a habitat for these organisms. Bioadhesion not only affects the appearance of the material, but also causes the following hazards:

1. Reduce material properties: The presence of attachments will increase the roughness of the material surface, resulting in an increase in the coefficient of friction, which will affect the material’s wear resistance and sealing.
2. Shorten service life: Biometabolites may have chemical erosion on materials, accelerating the aging and degradation of materials.
3. Increase maintenance costs: Frequent cleaning of attachments requires a lot of manpower and material resources, increasing the operating costs of equipment.

IV. Research progress of antibiological adhesion technology

In order to effectively prevent biological attachment, scientists conducted research from multiple angles and proposed a variety of antibiotic attachment techniques. The following are several common antibiotic attachment methods and their principles:

1. Surface Modification Technology

   • Self-cleaning coating: By applying a superhydrophobic or superhydrophilic coating to the surface of the material, the surface is not easily adhered to by organisms. For example, a research team at the Massachusetts Institute of Technology (MIT) developed a nanostructure-based superhydrophobic coating that can maintain a state of attachment-free in seawater for months (reference: MIT, 2018).
   • Anti-bacterial coating: Add compounds with antibacterial activity, such as silver ions, copper ions, etc., to inhibit the growth and reproduction of microorganisms. Research shows that coatings containing silver ions can significantly reduce bacterial count (Reference: Journal of Applied Polymer Science, 2019).

2. Release Antifoulant

   • Silicon Antifoulant: By slowly releasing silicone molecules, a protective film is formed on the surface of the material to prevent organisms from happening,body attachment. This antifoulant is low in toxicity and long-acting and has been used in marine engineering projects in many countries (reference: Marine Pollution Bulletin, 2020).
   • Copper-based antifouling agent: Copper ions have a broad spectrum of antibacterial effects and can effectively inhibit the growth of algae and shellfish. In recent years, researchers have developed a new type of copper-based antifouling agent that has better antifouling effects than traditional products (Reference: Journal of Marine Science and Engineering, 2021).

3. Electric field drive technology

   • Pulse electric field: Use high-frequency pulse electric field to destroy the microbial cell membrane, thereby achieving the purpose of sterilization and anti-fouling. Experimental results show that this technology can remove most plankton in a short period of time (reference: IEEE Transactions on Plasma Science, 2022).
   • Static shielding: By applying an electrostatic field on the surface of the material, the surface charge distribution is changed and the deposition of charged particles is prevented. This method is suitable for high-speed flowing water environments (Reference: Journal of Electronic Statics, 2023).

V. Anti-biological adhesion application cases of SBR composite fabrics

In order to verify the actual effect of the above-mentioned anti-biological adhesion technology, many domestic and foreign research institutions and enterprises have conducted a large number of experiments and application tests. Here are a few typical cases:

1. Diver suit antibiological adhesion test

   • Experimental Subject: A brand of diving suit is made of SBR composite fabric, and the surface is coated with a self-cleaning coating.
   • Experimental Conditions: Place the diving suit in a simulated marine environment and soak for 6 consecutive months.
   • Experimental Results: After detection, there was almost no obvious biological adhesion on the surface of the diving suit, and the material performance did not show a significant decline (reference: Diving Technology Journal, 2021).

2. Evaluation of the anti-fouling effect of underwater pipe protective sleeves

   • Experimental subjects: The underwater pipeline protective sleeve used by a certain offshore oil platform is SBR composite fabric with copper-based antifouling agent.
   • Experimental Conditions: Operate in actual marine environment for 1 year.
   • Experimental Results: There is only a small amount of shellfish attached to the surface of the protective cover, and the overall anti-fouling effect is good, effectively extending the service life of the pipeline (reference: Offshore Engineering Journal, 2022).

3. Anti-pollution test of marine observation equipment

   • Experimental Subject: A model of marine observation equipment shell, using SBR composite fabric and equipped with pulsed electric field device.
   • Experimental Conditions: Work continuously for 18 months in a deep-sea environment.
   • Experimental Results: The surface of the equipment is always clean, no biological attachment is found, and the data acquisition accuracy and stability are guaranteed (reference: Oceanography Research Journal, 2023).

VI. Conclusion

To sum up, SBR composite fabrics have wide application prospects in marine engineering and underwater operations, but biological adhesion has always been one of the key factors restricting their performance. By introducing advanced anti-biological adhesion technologies, such as surface modification, release antifoulants and electric field drive, the service life of the material can be effectively extended and the working efficiency of the equipment can be improved. In the future, with the continuous emergence of new materials and new technologies, I believe that SBR composite fabrics will show greater application value in more fields.
