Adhesives are a critical contributor to the structural load-bearing performance of the final wind blade assembly. They are therefore subject to long qualifications at blade manufacturers. The current turbine blade bonding technology may be completely reshaped by three opportunities : raw material availability, blade recyclability, and the evolution of blade designs.Note de contenu : - Evolving bonding technologies

SiliconesLes silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki).Index. décimale : 668.3 Adhésifs et produits semblables Résumé : If liquid-applied silicone shows bubbles after curing, it can potentially cause problems depending on the application. The right system technology eliminates air pockets and prevents processing issues. A modular system provides the flexibility to customize the material preparation and supply, based on the properties of the material to be processed. Note de contenu : - Preparation possibilities
