The price of anti-corrosion coatings has risen significantly nowadays, which is related to marine coatings and marine development. The country has been increasing investment in seven-tenths of the earth's oceans, and anti-corrosion coatings are a prominent point in this area.
Since 2007, anti-corrosion coatings have played an increasingly important role in the construction of the national economy. The market for anti-corrosion coatings for articles and defenses has shown a gratifying situation, and its production scale hascontinued to expand.
As early as 2010, the application of anti-corrosion coatings in my country has exceeded 3 million tons, becoming the world's largest anti-corrosion coating production and use volume. From 2007 to 2011, the total output value of my country's anti-corrosion coating industry continued to rise. In 2011, the total output value of my country's anti-corrosion coating industry reached 65.917 billion yuan.
Increase investment in offshore oil. The offshore oil production platform is a large steel structure fixed and semi-fixed in the ocean, which has been severely corroded by the marine environment for a long time. As the platform is far away from the mainland and it is difficult to maintain, it is required that the anti-corrosion coating has a protection life of at least 15 years. Therefore, a heavy-duty anti-corrosion coating and a long-lasting anti-corrosion coating supporting system with high durability must be adopted. Usually, the part below the sea level of the platform is mainly protected by sacrificial anodes or impressed current electrochemical protection, and the rest are protected by high-performance anti-corrosion coatings.
The scientific research of anti-corrosion coatings started early. Human beings have been researching the ocean continuously, and the resources in the ocean and the exploration of the ocean are slowly advancing, and progress in the ocean is inseparablefrom surface coating. China still has a long way to go for anti-corrosion coatings.
