Wind power blade coating with the crosslinking agent,Wind power blade coating with the crosslinking agent, wind energy is a kind of renewable nature has a great potential clean energy. Maintain rapid growth in recent years, the global wind power market. In 2015, the global wind power reached 63.69 GW of new power capacity, to an all-time high. Wind power is the key part of wind turbine blades, ensure the good operation, not only can improve the efficiency of power generation, and can reduce maintenance costs.
Affected by the natural environment, long running wind-power blades under strong light. Large temperature difference. The sand. Rain erosion. Snow and ice and water damage, so far the most simple and effective method is to use protective coating.
Suitable for wind power blade coating matrix resin, polyurethane resin currently include. Acrylic resin. Fluorine resin. Organic silicone resin and epoxy resin, etc..
In recent years, all kinds of the overuse of fossil fuels has led to a worldwide increasingly severe climate change and energy crisis, governments pay more and more attention to the development of new renewable energy. Wind energy is a clean. The sustainable utilization of new energy, and its rich resources. Widely distributed. Huge potential for development. The global wind power industry rapid development in recent years to get.
The world wind energy association statistics show that in 2015, the global new installed capacity reached a record 63.69 GW, more than 25% higher than that of 2104.
Wind generating set at run time by the temperature difference big. Ultraviolet light is strong. The wind sand impact wear. The corrosion of acid rain. Ice and snow hit. Moisture and salt fog corrosion and other severe weather conditions.
Wind-power blades at high speed, the speed of the blade tip tend to more than 100 m/s, it is also the thin parts, so are most vulnerable to wind sand abrasion and rain erosion damage. If does not carry on wind-power blades surface protection, the bad natural environment will lead to their wear. Aging and pulverization phenomenon, until the break, the serious influence power generation efficiency, shorten the service life of blade.
In addition, due to the large wind power blade lifting time-consuming and expensive, generally need to be in the running for more than 10 a maintenance.
Therefore, must carry on the coating to protect the wind vane, to improve its ability to resist erosion environment. Ensure the 20 a design service life.
The structure and properties of fluorine resin coating characteristics. Small fluorine atom radius (1.35 A). Electronegativity is great (4.0), F - C key in the key length (0.1317 nm). Key to high 486 kj/mol, 2 sum of van der Waals radius of fluorine atoms is 0.27 nm, basically can be C - C key completely surrounded, fluorine and carbon carbon atoms form helical structure, shielding the positive effect between the C - C key.

Due to the above characteristics, the fluorine atoms can well protect the C - C key, from ultraviolet radiation and chemical erosion, thus has excellent weather resistance. Chemical stability and corrosion resistance performance.
In addition, fluoropolymer low surface energy, has hydrophobic. Thin ice. Hydrophobic oil. The fouling resistance. As well as excellent self-lubrication and low friction performance.
The fluorine resin coating in the process of crosslinking, migration and enrichment of fluorine atoms happen to the coating surface, make the surface of the coating has excellent performance. Fluorine resin coating in weather. Corrosion resistance. Acid-proof alkaline. Resistance to chloride ion permeability. The fouling resistance. Hydrophobic and freeze resistance is better than the commonly used polyurethane coating in wind-power blades.
Therefore, the fluorine resin coating and its coating with other resin compound with applications in wind-power blades to cause the attention of everyone, and gradually become a future research direction.
In general, wind power blade coating should have some excellent performance and characteristics as follows:
(1) the weather (e.g., resistance to ultraviolet light); (2) high and low tender toughness; (3) the rain erosion resistance; (4) acid and alkali corrosion resistance; (5) wear resistance (sand impact wear); (6) good adhesion between substrate material (especially the primer coating and blade). (7), salt fog resistance and resistance to hot and humid; (8) the freeze resistance; (9) good construction performance; (10) low environmental pollution, etc
