Innovative materials through testing, indicates a lighter and more efficient fan blade era is coming
The world's leading supplier of high-performance polymer materials, Kesi Chuang announced, based on a new technology research and development of Polyurethane fan blades, successfully through the Beijing Hengwei Certification Center (CGC) static and fatigue testing (including the vibration and waving direction) At the 2017 Beijing International Wind Energy Conference and Exhibition, Kesi Chu announced the good news and presented the audience with its new polyurethane resin solution.
The tested wind turbine blades have a power of 2 megawatts and a length of 55.2 meters. The girders and webs are made of a new type of polyurethane perfumed resin from KSZ and TM + glass fiber from Chongqing International Composites Co., Ltd., the rest of the leaf Still used in the manufacture of epoxy resin.
In the design of the blade, manufacturing and testing and other aspects, Ke Si Chuang and the German blade design company WINDnovation, Luoyang Shuangrui Wind Power Blade Co., Ltd. and Beijing Jingheng Certification Center co-operation, for the success of the blade test has laid a solid foundation.
"The fan blade test is the key to proven long-term reliable operation of the blade," said Dr. Li Qian, Director of Asia Pacific R & D, Asia Pacific. The results show that polyurethane resins can meet stringent industry standards to meet the long-term use of leaves under harsh conditions This is another milestone in the DNV GL international certification, and this test also demonstrates that there is a strong interface between polyurethane and epoxy resin.
Use polyurethane to achieve lighter and stronger leaves
With a range of performance advantages, polyurethane makes it possible to make lighter and stronger blades, and lighter, more efficient blades can significantly reduce the need for wind turbine hub components and tower structures, thereby reducing overall fan investment And operating costs.
The interface between polyurethane and glass fiber is better than that of epoxy resin, and the material has better mechanical properties and excellent fatigue resistance. By optimizing the blade design, it has obvious advantages in lightweight blade design.
At the same time, polyurethane resin has a lower viscosity than the epoxy resin and better mobility, can save the perfusion time and improve the perfusion efficiency.Moreover, the polyurethane resin without post-curing, can greatly shorten the production time.In addition, the polyurethane resin Of the exothermic peak is also lower than the epoxy resin, which can reduce the heat of the resin on the impact of PVC foam core material.
Promote the wind revolution
As an innovative material, polyurethane resins help to build lighter and stronger fan blades to drive the development of the wind power industry, and in the future, China will build more wind power capacity in the low-speed eastern and central regions, which means higher And the longer blades to effectively capture the lower speed of wind, in order to improve power generation efficiency.In addition, offshore wind power is rapidly developing into an important trend in the development of wind power industry in large leaf applications, can better play Excellent performance of polyurethane resin.
Supporting Renewable Energy Power Generation is an important part of the philosophy of sustainable development, and for a long time, Kesi has always been committed to promoting the development of renewable energy for wind power, a pioneer in wind energy polyurethane applications. The two-component polyurethane heavy-duty material for wind turbine blades, polyurethane coatings for towers and blades, and polyurethane elastomers for blower submarine cables have been developed. The Polyurethane solution demonstrates the company's Wind power industry partners' long-term commitment to accelerate innovation and work together to promote the development of wind power industry.
