The primary function of photocuring anti-corrosion steel pipeline is to act as a photocuring coating. Under ultraviolet light, the photosensitive substances in the coating undergo a photochemical reaction, generating active particles or radicals. This initiates cross-linking and polymerization of the active resin, forming a solid protective layer that isolates the pipe from corrosive media and provides corrosion protection. What are the components of the coating?
Resin matrix: Bisphenol A epoxy resin and methacrylate provide the coating with excellent mechanical properties and adhesion.
Diluents: Castor oil polyglycidyl ether and toluene glycidyl ether reduce the viscosity of the resin and increase its activity, making them suitable for spray application.
Photoinitiator: This absorbs ultraviolet energy to initiate the polymerization reaction of the resin, playing a crucial role in the entire UV-curing process.
Other additives: During use, photocuring anti-corrosion steel pipeline must possess curing properties, heat resistance, antioxidant properties, and corrosion resistance, so these additives must also perform these functions.
The service life of photocuring anti-corrosion steel pipeline depends on the coating technology, environmental conditions, and maintenance. If used in moderate environments, they typically last 30-50 years. If exposed to harsh conditions, such as high salinity and acidic environments, they can last 20-30 years. Key influencing factors include:
Coating technology: Self-healing coatings extend service life through self-repair.
Operation environment: Compared to controlled environments, marine or industrial environments containing chlorides or hydrogen sulfide can shorten service life by 10-15 years.
Maintenance and servicing: Maintenance and servicing of photocuring anti-corrosion steel pipeline can identify problems that may arise over time, such as defects or surface wear. Prompt repairs can extend service life.
Compared to traditional corrosion protection technologies, photocuring anti-corrosion steel pipeline offer significant advantages over traditional corrosion protection technologies in long-term use and exhibit strong resistance to failure. UV-curing coatings offer a high cross-link density and strong chemical stability, with an anti-corrosion lifespan typically reaching 15-20 years. During use, the coating maintains excellent adhesion, and the breakage-resistant corrosion inhibitor creates a "localized protection zone," significantly reducing the rate of corrosion and requiring minimal maintenance. The entire solvent-free, room-temperature curing process eliminates the risk of coating carbonization and contamination of the conveying medium, making it suitable for applications requiring stringent pipeline hygiene requirements.
When using pipelines, users are not only concerned about performance characteristics, but also about their environmental characteristics. The emission of pollutants will pollute the atmosphere, and each of us should strive to save energy and reduce emissions. From production to use and then to disposal, the entire process of photocuring anti-corrosion steel pipelines avoids the pollution problems of traditional processes. The solvent-free design and room temperature curing mechanism of light-curing anti-corrosion technology can control VOCs emissions below 5g/m2, which is much lower than traditional anti-corrosion processes. The light-curing coating converts all components into a solid film through a complete polymerization reaction, without the risk of solvent residue. When transporting drinking water and food, it truly prevents corrosion and pollution.
