Recently, under the call of the Chinese government to promote energy conservation and emission reduction, the variety and function of coatings have also been continuously enriched and innovated. Whether each coating enterprise, raw material and equipment supplier has a high cost performance ratio and can "promote downstream product value-added" "overall solution" tailored to the actual product and engineering problems of downstream users will become an important reference for measuring the core competitiveness of enterprises.
The development of new energy sources in automobiles and the rise of new energy sources in the paint industry. Wind power generation is a rapidly developing new energy industry in recent years. Compared to thermal power, wind power does not consume carbon stone energy and does not emit carbon dioxide; Compared to nuclear power, the core technology of wind power is less difficult and there is no potential danger of nuclear leakage; Compared to hydropower and geothermal power generation, the initial construction investment is relatively small. The main parts of the wind power coating are the tower and blades, and the coatings used vary greatly due to different substrates. In recent years, China has invested tremendous efforts in wind power generation, and wind power equipment can be seen in many places along the northwest, northeast, and southeast coasts.
With the vigorous development of China's wind power industry and the complexity of the domestic wind farm environment, the improvement of anti-corrosion technology for wind power equipment has become an urgent task. Fluorocarbon coatings have enormous potential in the future wind power market. Introducing the wind power anti-corrosion market in the future can greatly improve the weather resistance, corrosion resistance and other performance of wind power equipment, extend the protection period of equipment, and reduce maintenance costs. In the future, wind power equipment in China will become a representative of new energy in China and even the world, a new pillar of global energy, and energy conservation and environmental protection will become synonymous with wind power energy.
The wind turbine system is subject to various harsh environmental erosion at any time, such as wind and sand, ultraviolet radiation, temperature difference, rain and snow, icing, etc. Especially for offshore wind power, it is subject to long-term erosion by water vapor, salt mist, and waves, resulting in corrosion problems. Therefore, to ensure the normal service life of wind power equipment for 20 years, relevant protective measures must be taken, and coating protection is an important part of it. Wind power protective coatings mainly include tower anti-corrosion coatings and blade protective coatings, while tower bases, wheel hubs, bearings, engine hood, fairing, and other electrical equipment also require coating protection.
After 2010, China will become the world's largest wind power market and wind energy equipment manufacturing center. China is at a great time to generate wind power. According to the 11th Five Year Plan, by 2010, China's installed wind power capacity will reach 5 million kilowatts, 10 million kilowatts in 2015, and 30 million kilowatts in 2020. Anti corrosion coatings will have greater development and application.
The concept of heavy-duty anti-corrosion coatings originated in Japan in the 1960s, referring to coatings that have a long service life and are applied in harsh corrosive environments. The so-called harsh corrosive environment refers to a highly corrosive environment. According to the definition of ISO 12944-2, it refers to a corrosive environment in which the atmospheric environment is C4 (high), C5-I (very high industrial), C5-M (very high marine), and Im2 is immersed in seawater or saline water. The so-called long-term service life has no exact definition, and it is generally believed to be greater than a service life of more than 5 years, which is the medium or high coating service life specified in ISO 12944-5.
The characteristics of heavy-duty anti-corrosion coatings
High thickness film, good surface treatment performance, and the application of new resins and fillers all determine the excellent performance of heavy-duty anti-corrosion coatings, which have made immortal contributions in the process of national construction.
The industrial revolution in various European countries in the mid-17th century ushered in a new era of paint development. On the one hand, the development of social productivity and the improvement of living standards constantly put forward new requirements for the variety and quality of coatings. On the other hand, the progress of science and technology, especially the development of organic chemistry, and the continuous emergence of new resins have provided possibilities for the large-scale production of coatings. However, overall, the anti-corrosion performance of these coatings is average, and the protection cycle of coatings is relatively short. It was not until 1967 that the emergence of thick film epoxy coatings gave rise to truly significant heavy-duty anti-corrosion coatings.
The widespread application of wind power equipment in China and the vigorous promotion in the international market, such as the introduction of wind power anti-corrosion market in the future, can greatly improve the weather resistance, corrosion resistance and other performance of wind power equipment, extend the protection period of equipment, and reduce maintenance costs. Wind power equipment will eventually win in the future energy war, and its environmental protection, energy-saving and other characteristics enable it to stand out among the crowd.
