The wind power coatings market has broad prospects

supplier Norwegian Jotun company not only brought paint applications in the field of oil and gas, to the surprise of reporters, they also brought a full range of product solutions in the field of wind power. Its product manager told this newspaper that Jotun has been actively involved in research and solve the problem of corrosion protection in the offshore wind industry, is committed to providing a full range of protection for offshore wind power projects, covering piles, towers, blades, cabins, substations and installation ships.
In this oil and petrochemical as the main character of the exhibition, in addition to Jotun, such as the Danish Haihong old man and other paint companies have also brought in the field of wind power application solutions, in the wind power market to warm up at the present time, upstream and downstream supporting the field of wind power attention can be seen.
in accordance with the "China Wind Power Development RoadMap 2050" target, by 2020, 2030 and 2050, China's installed wind power capacity will reach 200 million, 400 million and 1 billion kilowatts, respectively, by meeting 5%, 8%, 17% of the electricity demand. It is estimated that in the seven years from 2013 to 2020, China's wind power coating gap is 130,000 tons, which is about 7 billion U.S. dollars of market capacity.
wind power industry is developing rapidly in China, but as an important supporting industry, domestic wind power coatings start relatively late. Northwest Yongxin Group in recent years wind power coatings as one of the business development priorities, its party committee work director Wang Hongwu said that in 2006 China has become the world's largest producer of wind power equipment. However, domestic wind paint is basically monopolized by foreign products, tower coatings are monopolized by more than 80%, blade coatings are monopolized by more than 95%. Although domestic manufacturers to carry out domestic wind paint research and development and application, but resin and other major raw materials still need to rely on imports, the core technology localization rate is very low.
wind farms are mainly concentrated in the western desert area and the eastern offshore area. Desert areas wind and dust, wind turbine systems will encounter a variety of adverse environmental erosion, offshore areas have long been affected by water vapor, salt spray erosion and waves, prone to corrosion problems. This requires relying on
and anti-corrosion
to ensure the safe operation of the equipment and the continuation of life.
according to the China Coatings Industry Association related people, in the field of wind power products, the largest use of tower coatings, the most technical challenges are blade coatings. In addition to the two, including transformer coatings, rectifiers and cabin cover coatings, buried foundation rings and reinforced coatings, electrical cabinet coatings, generators and other in-cabin equipment coatings.
demand for wind blades in China will reach 50,000 in 2014-2020, according to the World Wind Energy Association.
Chinese technology wind blades Co. , Ltd. related people told reporters that how to minimize external erosion will be the key factor in determining the actual life of blades, and the use of the most direct and effective protection of blades of the paint has become the only choice. Global

that with the continuous expansion of the capacity of wind turbine units, the requirements for wind power coatings are also increasing. For example, fan blades have grown from small blades of about 20 meters in length to blades 70 meters or more today, and corresponding blade coatings must be developed accordingly.
from the National Chemical Industry Productivity Promotion Center learned that wind power equipment manufacturing industry as a new industry, in the early stage mainly rely on foreign technology. In the full set of introduction and its later digestion process, gradually formed a simple dependence on foreign supporting systems, including coatings. Therefore, it also caused wind power coatings long-term monopoly by foreign brands, direct import or local production of the status quo.
" in 2008 after the decline of the traditional coatings market, many enterprises are looking for new applications in the market, have focused on the development direction of the wind power coatings that were emerging in China at that time. The above-mentioned person of the China Coating Industry Association said.
, in the tower coating, Denmark Haihong old man, Norway Jotun, the Netherlands AkzoNobel, the United States PPG and other market share is higher. In terms of blade coatings, Germany's Meikevich, the United States PPG, Germany's BASF and other dominant positions.
in the industry, the advantages of foreign brands are technological innovation, quality control stability and decades of accumulated experience. However, a wind farm in the west of the relevant person in charge told reporters that the experience of foreign brands is more based on the european excellent climate in the operating performance of wind farms, and in the face of China's wind farms are mostly located in the wind and sand impact area of the status quo, but also need to solve the problem of how to adapt to the new environment.
how to better meet the special environmental requirements of China's wind farms, which may also be the domestic wind coatings industry to catch up with a breakthrough point.
Northwest Yongxin Group officials told reporters that from 2008 onwards, they jointly with universities, research institutes, for China's wind farm wind farm wind turbine coating wind-resistant sand, ultraviolet, anti-ice and other needs to carry out technical research, achieved a partial breakthrough, has now become a gold wind technology, Huatron wind power and other machine enterprises qualified suppliers.
domestic enterprises are also trying to achieve the application of new materials to foreign
brand
catch up. At the end of last year, Changzhou Sixth Element Technology Co., Ltd. and Jiangsu Haili Wind Power Equipment Technology Co., Ltd., Jiangsu Dawson New Materials Co., Ltd. signed the "Graphene anti-corrosion coating strategic cooperation framework agreement" to jointly develop graphene as the main body of zinc-type protective coatings for offshore wind power equipment. It is said that the anti-corrosion effect of this new coating is more than 4 times that of the traditional
heavy anti-corrosion coating
, and graphene coating can make the paint film thinner, increase the coating area, improve the use of paint.

the head of the wind paint industry to rise, must have the corresponding standards to support. We must improve and formulate wind power coating industry standards in line with the current situation of wind farms in China as soon as possible. It is understood that three years ago, Changzhou Coatings chemical research institute began to lead the development of wind power coatings national standard "wind farm paint protection and construction norms", but so far has not been introduced. "If it goes well, it could come in the second half of the year." The relevant person in charge of the hospital revealed.
" Because there is currently no wind blade coatings related industry standards, coating enterprises in the development of blade coatings lack a clear technical reference, usually rely on their own understanding and blade manufacturers put forward technical requirements to develop enterprise standards, which is not conducive to the overall development of China's wind coatings industry. "China Paint Industry Association related experts said. according to
, modern large-scale wind blades mainly originated in Europe near the Baltic Sea and the North Sea, where the North Atlantic warm currents, mainly warm and humid temperative oceanic monsoon climate, its wind source is characterized by high water content, sand content and dust content are very low. Therefore, the European leaf coating standards will be rain-resistant erosion as its main detection indicators. The main wind farm in our country is located in the desert area of wind and sand, drought and little rain, and the damage of the peripheral system of the wind turbine mainly comes from the erosion of wind and sand. Therefore, we can not copy the requirements of foreign indicators when setting standards for wind power coatings.
