U.S. General Motors Designates Special Blade Anticorrosion Coatings

Wind turbine blades are one of the core components of wind turbines. Epoxy glass-fiber reinforced composites are mainly used. They require a service life of up to 20 years and need to be protected by key coatings. The effective protection depends on the design of the protective coating, the surface treatment, the coating process, the quality of the coating and the control of the coating quality. The wind turbine requires a service life of more than 20 years. The blades of the existing MW wind turbine units are glass fiber reinforced epoxy composite materials. The epoxy resin has excellent adhesive properties, and the impact toughness can reach 255 KJ/m2. The corrosion resistance is excellent. And so on, but at present, the coating products selected for domestic use are thin in coating, low in adhesion, and poor in weatherability, and cannot meet the requirements for corrosion protection. In order to fully guarantee the service life of the wind turbine, the protection of the blade is particularly important.

The high-quality protective effect depends on many factors such as the design of the protective coating, the surface treatment of the FRP substrate, the reasonable coating process, the quality of the coating, and the effective coating quality control. The original American Xuanwei wind power equipment special paint supporting system can fully meet and exceed the technical indicators and requirements of various aspects. It is the world's designated special paint and supplier for GE (general-purpose company's aircraft blades) and German Siemens wind power equipment. US Xuanwei wind power blade coating assembly program, set 140 years of coating scientific research results, to provide customers with up to 20 to longer anti-corrosion package program to ensure value for money.
