Marine engineering is a challenging area, especially in the selection and development of materials. High salinity, high humidity and strong corrosiveness in the marine environment puts extremely high requirements on the durability of the material. To address these challenges, scientists continue to explore new materials and technologies. This article will introduce in detail the development process of a new catalyst ZF-20 in marine engineering, including its product parameters, application scenarios, advantages and future development directions.
Catalytic ZF-20 is a new nanoscale catalyst designed specifically to improve the corrosion resistance of materials. It significantly enhances the durability of the material in harsh environments by changing the surface structure and chemical properties of the material.
Catalytic ZF-20 is mainly composed of the following components:
| Ingredients | Proportion (%) | Function Description |
|---|---|---|
| Nanozinc oxide | 45 | Providing high corrosion resistance and stability |
| Silica | 30 | Mechanical strength and wear resistance of reinforced materials |
| Rare Earth Elements | 15 | Improving catalytic activity and corrosion resistance |
| Other additives | 10 | Modify the physical and chemical properties of catalysts |
Catalytic ZF-20 improves the corrosion resistance of materials through the following mechanisms:
Ocean platforms are important facilities in marine engineering. They are exposed to harsh marine environments for a long time and are extremely susceptible to corrosion. Materials treated with catalyst ZF-20 can significantly extend the service life of the marine platform.
On the steel structure of a certain offshore oil platform, steel treated with catalyst ZF-20 did not show obvious corrosion within five years, while untreated steel showed serious corrosion within two years.
Subsea pipelines are important channels for transporting oil and natural gas, and corrosion problems will seriously affect their safety and reliability. The catalyst ZF-20 can be used for the inner and outer coating of the pipe to effectively prevent corrosion.
In a submarine natural gas pipeline project, the pipeline treated with catalyst ZF-20 did not have any corrosion leakage accidents within ten years, while the untreated pipeline showed multiple corrosion points within five years.
Ships sail in the ocean for a long time, and their hulls and equipment are extremely susceptible to corrosion. The catalyst ZF-20 can be used for hull coating and equipment surface treatment to improve the durability of the ship.
In the hull coating of a large cargo ship, the coating treated with the catalyst ZF-20 showed no signs of corrosion within three years, while the untreated coating showed multiple corrosion points within one year.
