Products Description
The quality standards of shipbuilding steel plates will change with the changes in the environmental protection requirements of ships, which are specifically reflected in the following aspects:
In terms of corrosion resistance performance
Driven by environmental protection regulations
Necessity of standard adjustment: With the increasingly strict environmental protection regulations on the emission limits of pollutants from ships, ships need to better prevent the loss of shipbuilding steel plates caused by seawater corrosion during the operation process. Because the corroded shipbuilding steel plates will not only shorten the service life of the ship, but also may increase the frequency of ship maintenance and component replacement due to structural damage, resulting in more waste and pollutant emissions.
Change of specific performance requirements: In order to meet the environmental protection requirements, the corrosion resistance performance standards of shipbuilding steel plates need to be improved. For example, for ships operating in some sea areas with higher environmental protection requirements, their shipbuilding steel plates may need to increase the corrosion resistance years from the original 10 - 15 years to 15 - 20 years. This prompts the shipbuilding steel plate quality standards to be adjusted in terms of corrosion resistance performance by increasing the content of corrosion - resistant alloy elements. For example, the content of chromium may be increased from the original 0.5% - 1.0% to 1.0% - 1.5% to enhance the corrosion resistance ability of the shipbuilding steel plates in the seawater environment.

In terms of coating environmental protection
Reduce the use of harmful substances
Demand for environmentally friendly coatings: Ships usually apply coatings on the surface of shipbuilding steel plates to prevent corrosion, and some traditional coatings may contain substances harmful to the environment, such as volatile organic compounds (VOCs). With the improvement of environmental protection requirements, more environmentally friendly coatings need to be used, which also indirectly affects the quality standards of shipbuilding steel plates.
Changes in requirements for shipbuilding steel plates: In order to adapt to the application of environmentally friendly coatings, the surface quality standards of shipbuilding steel plates need to be more strict. For example, it is required that the surface roughness of the shipbuilding steel plates is more uniform, and the fluctuation range of the roughness value is reduced from the original ±5μm to ±3μm, so that the environmentally friendly coating can better adhere to the surface of the shipbuilding steel plates and improve the protection effect of the coating. At the same time, the cleanliness of the surface of the shipbuilding steel plates also needs to be improved, and the allowable content of impurities such as oil and dust is reduced from the original not more than 100mg per square meter to not more than 50mg per square meter to ensure the bonding force between the environmentally friendly coating and the shipbuilding steel plates.
