Henkel innovation breakthrough Polyurethane adhesives have been awarded for the first time by German Lloyd's Classification Society for blade bonding technology
In wind turbines, the blade tip rotates at speeds of up to 300 km/h and resists the huge pressure load. The quality of the moving blades undoubtedly depends on the quality of the adhesive. A few days ago, German Lloyd's Register issued the first polyurethane adhesive certification in the field of wind energy. The honor is awarded by MacroGold UK 8340 developed by Corporation adheres to its consistent strategy and develops sustainable adhesive solutions to add value in the areas of ecology, quality and economy.
Wind turbines must operate stably for 20 years without major overhaul. The design of rotor blades in large turbines must also meet stringent fatigue strength standards. Conventionally, blade bonding is usually carried out using a German Lloyd's Register (GL) certified epoxy adhesive. Since the was developed, became the first company to use GL-certified polyurethane adhesives in the production of moving blades. This new technology brings many benefits to wind turbine manufacturers, helping them to optimize production processes, increase productivity, and reduce costs. At the same time, developed this product with excellent sustainability.
In the field of wind energy applications, has developed a range of products, such as UV-resistant and weatherproof sealants, anaerobic threadlockers, various types of adhesives for bonding components, and for GRP removal. Mold water-based release agent. The emergence of the two-component polyurethane adhesive reinforces leading position in adhesive and sealant technology. Compared with epoxy adhesives, polyurethane adhesives for blade attachment are extremely innovative and greatly increase the freedom in the production process of moving blades.
can quickly condense. Polyurethane adhesives react faster than traditional epoxy resins, accelerating the production process and greatly increasing productivity. "The heat release during the curing of two-component polyurethane adhesives shortens the tempering time and lowers the temperature at this stage," said Hartmut Pilz, Wind's marketing manager. For moving blade manufacturers, this product can greatly save energy and has a positive ecological impact on comprehensive assessment. At the same time, the adhesive reduces the risk of cracking due to pressure due to use in low temperature environments.read purglue
Another feature of polyurethane adhesives is their good wetting properties, which can greatly reduce the time-consuming and costly initial work of sandpaper sanding and plastic sealing. Compared with traditional adhesive technology, has increased the possibility of optimizing the production process of moving blades and opened up a vast new space for it. innovative polyurethane technology has increased the efficiency of the entire production process and set new standards for its sustainability.
