Wind power green coating link water-induced into a development trend

At present, the situation of air pollution prevention and control is serious, and speeding up the reduction of volatile organic compounds (VOCs) in industrial enterprises is of great significance for promoting the green development of industry and improving the quality of the atmospheric environment.
At a recent seminar on environmental protection coatings for industrial water-based lacquered wind towers co-sponsored by the Wind Energy Professional Committee of the China Renewable Energy Association, the Wind Energy Equipment Branch of the China Agricultural Machinery Industry Association and wind energy magazine in Beijing, the Secretary-General of the Wind Energy Equipment Branch of the Agricultural Machinery Industry Association, Yu Hesheng, said Recently, the Ministry of Industry and Information Technology and the Ministry of Finance issued a special letter on the serious situation of air pollution in China to speed up the reduction of organic compounds in industrial enterprises, including the promotion of the use of low or non-volatile organic compounds paint products, promote industrial green development, promote the improvement of the quality of the atmospheric environment, to protect human health. As a clean energy wind power generation, it is the responsibility to achieve green manufacturing, control VOCs emissions, and actively fulfill environmental responsibilities.Wind power calls for green coating
said at the conference, on the one hand, the trend of green, low carbon has been irreversible, which is the consensus of all countries in the world, on the other hand, in view of the current serious situation of air pollution prevention and control, accelerate the reduction of VOCs industrial enterprises, to promote industrial green development, promote the improvement of atmospheric environmental quality, to protect human health is of great significance.
background, the reporter learned that recently by the Ministry of Industry and Information Technology, the Ministry of Finance jointly issued the "key industries volatile organic matter reduction action plan" (hereinafter referred to as the "Plan").
the Plan clearly states that industry is the focus area for VOCs emissions, which account for more than 50 per cent of total emissions. By 2018, VOCs emissions from the industrial sector will be reduced by more than 3.3 million tons compared to 2015, reducing the use of solvents such as benzene, toluene, methamphetamine (DMF) by more than 20%, and the proportion of green pesticide preparations, coatings, inks, adhesives and tire products in low (none) VOCs will reach 70%, 60%, 70%, 85% and 40%, respectively.
noteworthy, the Plan also makes it clear that the future will focus on the promotion of water-based coatings, powder coatings, high solids, solvent-free coatings, radiation curing coatings (UV coatings) and other green paint products.
, Director of the Environmental Protection Department of the Department of Energy Conservation and Integrated Utilization of the Ministry of Industry and Information Technology, believes that without green development, it is impossible for a strong country to achieve green development before a strong country. Wind energy is a green energy, with the supporting equipment and technology must also require that it must be green, water-based industrial paint can effectively promote wind power equipment green environmental protection.
this view is in line with Qin Haiyan, secretary-general of the Wind Energy Professional Committee of the China Renewable Energy Association. Qin Haiyan said that although wind power is clean energy, there are still some pollution problems in the equipment production process. The promotion of water-like paint is to hope that the entire industry from equipment production, application to end products are practiced clean green concept.wind power calls for green coating
by the impact of good policies continue to increase the code, China's wind power industry continued last year's surge. The State Energy Administration recently released the "first half of 2016 wind power grid operation" shows that in the first half of this year, China's wind power added grid capacity of 7.74 million kilowatts, by the end of June, the cumulative grid capacity reached 137 million kilowatts, the cumulative grid capacity increased by 30% year-on-year, the growth rate is quite obvious.
development of wind power industry has also brought new opportunities to the development of related industries, paint is one of them.
, chief engineer of Hua leopard (Tianjin) Paint Co., Ltd., believes that, on the one hand, wind power coatings are supporting industries, but the impact on the wind power industry can not be underestimated. According to the preliminary plan, the future installed capacity of wind power is expected to reach 200 million to 250 million kilowatts, wind power equipment market will be as high as 140 billion to 210 billion yuan, the development prospects are good;
a participant told reporters that the current corrosion of materials, structural parts and equipment will indeed bring greater economic losses. Specifically, wind turbine systems can be eroded by a variety of harsh environments due to the fact that wind power plants are mostly built in uninhabited areas such as deserts and are large in wind and dust. At the same time, offshore wind power has long been affected by water vapor, salt spray erosion and waves, prone to corrosion problems, so we must rely on anti-corrosion coatings to ensure the safe operation of equipment and the continuation of life.
Wu Zhanhai, Minister of Jinfeng Science and Technology, believes that because corrosion is a slow process, the long-lasting anti-corrosion performance of the coating must be guaranteed, which requires that the laboratory stage data and the evaluation of the later effects must be well-founded, especially the in-depth research and development of water-based paint can not be interrupted."oil" to "water" is an unchangeable trend
relevant data show that more than 90% of the global wind power industry is currently using solvent-based coatings as anti-corrosion coatings. Although the technology has been very mature, but the pollution of the environment, human health hazards and in the process of production and transportation, the existence of safety hazards is also an unavoidable fact.
, industry experts at the meeting said that water-based environmental protection coating water as a dispersion medium and thinner, the raw materials used in the coating are non-toxic and harmless, so the coating is also non-toxic and non-polluting. The biggest difference between this coating and solvent-based coating is the use of water as a solvent, which greatly reduces the emission of volatile gases from organic solvents. As one of the most common resources, freshwater resources greatly simplify the process of coating dilution. At the same time, the new functional materials are very easy to transport and store, these characteristics are incomparable organic solvent coatings.
Wang Aimin, the footprint of water-colored paint can be traced back to the 1980s. After more than 30 years of continuous development, the performance of water-like paint is also constantly improving, has reached the requirements. The paint industry's plan for the next five years clearly sets out the policy of "innovation and development, coordinated development, advantageous development and green development", and by 2020, cost-effective and environmentally friendly coatings will account for 57% of the total. All the above indications show that the hydration of the coating process is an unchangeable trend.
, some eastern provinces have gradually introduced their own rules, which include sewage charges or VOCs emissions tax rates. As we can see, Beijing launched on October 1, 2015, a punitive rate of up to 40 yuan per kg of VOCs emissions, including the city's final rate of 20 yuan per kg on January 1, 2017. "Hansen Chemical Enterprise Management (Shanghai) Co., Ltd. paint civil engineering account manager Zhang Ran also said that from various signs of analysis, the final cost of the use of solvent-based coatings is likely to increase significantly, and even in this regard, the levy may exceed the value of the coating itself. Therefore, measures in this regard, for the development of water-based coatings may be an opportunity.
However, although the development prospects of water-like paint is good, but for the current water-like paint in the wind power industry promotion encountered specific problems, the certification center wind energy division parts minister Li Haoran also pointed out that, although in the fan tower and other equipment has been the use of water-like paint cases, but a large number of water-specific paint products in the wind power industry in the specific applications also need to be further verified and standardized by technical means.
