Protective coating application of catalyst ZF-20 on wind turbine blades
Introduction
Wind power generation, as a clean and renewable energy form, has been widely used in recent years. As the core component of the wind turbine, the wind turbine blades directly affect the power generation efficiency and service life. However, the leaves are exposed to harsh natural environments for a long time and face many challenges such as wind and sand erosion, ultraviolet radiation, and rainwater erosion. Therefore, how to effectively protect the blades and extend their service life has become an urgent problem that the wind power industry needs to solve.
As a new type of protective coating material, the catalyst ZF-20 has gradually emerged in the field of wind turbine blade protection due to its excellent weather resistance, corrosion resistance and wear resistance. This article will introduce the product parameters, application advantages, construction technology and specific application cases of catalyst ZF-20 on wind turbine blades in detail, aiming to provide reference for relevant practitioners.

2. Application advantages of catalyst ZF-20
1. Excellent weather resistance
The catalyst ZF-20 has excellent weather resistance and can effectively resist the influence of harsh environments such as ultraviolet radiation, high temperatures, and low temperatures. After 2000 hours of QUV testing, there was no obvious change in the coating surface, ensuring that the blades can still maintain good appearance and performance during long-term use.
2. Excellent corrosion resistance
Wind generator blades are exposed to marine or industrial polluted environments for a long time and are susceptible to corrosion by corrosive substances such as salt spray and acid rain. The catalyst ZF-20 has excellent corrosion resistance. After 1000 hours of salt spray testing, the coating surface has no corrosion, which effectively extends the service life of the blade.
3. Good wear resistance
When the blades are run, they will be washed by wind, sand and rain, causing surface wear. The catalyst ZF-20 has excellent wear resistance. After 500 cycles of wear tests, there is no obvious wear on the coating surface, ensuring that the blades can still maintain a good surface state during long-term use.
4. Excellent adhesion
The adhesion of the catalyst ZF-20 to the blade substrate is excellent. After level 1 adhesion test, there is no peeling between the coating and the substrate, ensuring the long-term stability and reliability of the coating.
5. Wide applicability
Catalytic ZF-20 is suitable for a variety of substrates, including fiberglass, carbon fiber, aluminum alloy, etc., and can meet the protection needs of different types of wind turbine blades.
III. Construction technology of catalyst ZF-20
1. Surface treatment
Before coating the catalyst ZF-20, the blade surface needs to be thoroughly cleaned to remove impurities such as oil and dust. For old coatings, grinding is required to ensure that the surface is flat and without residue.
2. Primer coating
To improve the adhesion of the coating, it is recommended to apply a primer first. The choice of primer should be based on the type of blade substrate to ensure that the primer has good compatibility with the catalyst ZF-20.
3. Catalyst ZF-20 coating
Spray the catalyst ZF-20 evenly on the surface of the blade, and it is recommended to use spray or brush coating. The coating thickness should be adjusted according to actual needs. It is generally recommended to apply 2-3 layers, and the thickness of each layer should be controlled at 20-30 microns.
4. Drying and curing
After the coating is completed, place the blades in a well-ventilated environment for drying and curing. The drying time is adjusted according to the ambient temperature and humidity. The surface drying time is generally 30 minutes and the practical drying time is 24 hours.
5. Quality Inspection
After drying and curing, the coating is subjected to quality inspection.Including appearance inspection, adhesion testing, wear resistance testing, etc., to ensure that the coating quality meets the requirements.
IV. Specific application cases of catalyst ZF-20 on wind turbine blades
1. Case 1: An offshore wind farm
A certain offshore wind farm is located on the southeast coast of my country. The blades of wind turbines are exposed to high humidity and high salt spray for a long time, and face serious corrosion problems. After the protective coating was treated with catalyst ZF-20, a dense protective film was formed on the surface of the blade, which effectively resisted the erosion of salt spray and moisture. After one year of operation, there is no obvious corrosion on the surface of the blade, good coating adhesion, and stable blade performance.
2. Case 2: A certain inland wind farm
A certain inland wind farm is located in the northwest region of my country. The blades of wind turbines have been affected by wind and sand erosion and ultraviolet radiation for a long time, and the surface wears severely. After the protective coating is treated with catalyst ZF-20, a high-hard protective layer is formed on the surface of the blade, which effectively resists the erosion of wind and sand and ultraviolet radiation. After two years of operation, there was no obvious wear on the surface of the blade, the coating hardness was maintained, and the service life of the blade was significantly extended.
3. Case 3: A high-altitude wind farm
A high-altitude wind farm is located in the southwest of my country. The blades of wind turbines are in low temperature and high humidity for a long time and are facing the challenge of freeze-thaw cycles. After the protective coating was treated with catalyst ZF-20, a low-temperature-resistant protective film was formed on the surface of the blade, which effectively resisted the influence of freeze-thaw cycle. After three years of operation, there is no obvious freeze-thaw damage on the surface of the blade, good coating adhesion, and stable blade performance.
