Because of wind energy resources all over the world, wind power generation technology continues to develop, wind energy has become one of the most promising renewable energy. The global installed wind power capacity, which is growing at a double-digit rate, also confirms this point. However, in order to achieve further expansion and compete with traditional energy sources, the need for cost-effective wind turbine equipment production processes is more urgent than ever.

Previously, Covestro announced that it has successfully developed the world's first 64.2 meter long, all-polyurethane resin fan blade with Chinese wind turbine manufacturer Goldwind Technology, achieving a major breakthrough in the application of this material in the field of large-scale fan blades. In this project, a Boray ® specially developed by Covestro's elastomer department; A polyurethane resin injection device was instrumental.

Philippe Jeantin, Global Equipment Director of Elastomers at Covestro, said: "This Boray ® The in-line vacuum filling device was developed by Covestro Elastomers specifically for the in-line filling of fan blades to solve various production challenges, such as the efficient and rapid filling of large fan blades under vacuum. The equipment has high measurement accuracy, intelligent flow adjustment according to the pressure in the mold, and real-time data management function, thus ensuring the quality of the direct perfusion process during the production of large fan blades."

New online vacuum perfusion equipment, help the whole polyurethane resin blade processing

"Today, with the rapid development of the wind energy market, we are facing the challenge of efficient production of large fan blades." "Therefore, we have been looking for a reliable partner who can provide us with perfusion equipment to meet the needs of large-scale polyurethane fan blade production," said Liu Baofeng, director of fan blade materials and professor level senior engineer of Goldwind Technology. The online perfusion equipment provided by Covestro fully meets the production needs of 64.2 meters of large polyurethane blades of our company, and will certainly promote the entire industry towards the direction of large blades. In the future, the two parties will strengthen cooperation on materials and related equipment, in order to more effectively promote the continuous innovation and upgrading of the whole fan blade materials."

"The successful launch of the world's first all-polyurethane fan blade is proof that Boray ® The capability of the equipment in the field of polyurethane on-line vacuum perfusion. Our local equipment team will fully support our wind power industry partners in achieving high growth and technology upgrading goals." Chen Min, Regional director of Covestro Ballistic Devices Asia Pacific.

With the rapid development of the wind power industry, large-scale fan blades have become a trend. Covestro has always been committed to providing innovative products and cost-competitive total solutions for the wind power industry to meet market demand and support the development of renewable energy. By working with industry partners such as Goldwind, Covestro will continue to contribute to the high efficiency development of the wind power industry.
