Liaisons chimiquesIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : How do you make adhesives for electronics, vehicles, and construction tougher? By making them weaker. That’s the proposed solution from a Purdue University research team.
"We have been using inspiration from sea creatures to develop several new adhesives", said Jonathan Wilker, a Purdue professor of chemistry and materials engineering who helps lead the research team. "Recently we have been seeking strategies for making adhesives tougher. One way to get there can be viewed as making the materials tougher by, first, making them weaker".Note de contenu : - Creating sacrificial bonds

Température -- ContrôleIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Prior to the 1980s, it was common for cars to rust. The lower doors and rocker panels were usually the first to go, followed by the floor pans, wheel wells and bumpers. Even the hood, deck lid and the roof were not immune. Aftermarket companies sprang up to “undercoat” cars to prevent rust. Automakers followed suit and offered undercoating as an option as they sought a solution.
Next came modern sealer technologies, which offered the opportunity to prevent corrosion in the places where it was most prevalent. This was far better than aftermarket solutions, which involved drilling holes and installing plugs after spraying. Sealers were incorporated into both the design and the manufacturing process. First applied manually, the sealers were an improvement, but still were unreliable.
In the ’80s, robotics were just coming into their own, and they offered the opportunity to automate the repetitive, tedious, high-precision tasks of which humans quickly grow tired—including the application of sealer. But there was one major problem: hand-eye coordination. A human could watch the bead as it was being applied and change their speed, angle, distance to the part, etc., to create a good bead―something a robot wasn’t capable of doing. For a while, it seemed like robots weren’t cut out for this type of application. Then, in 1990, Saint Clair Systems (SCS) introduced new methods and devices for controlling the temperature of the sealer as it was dispensed, making the application viable. Today, robotically applied sealer is the norm throughout the industry, and virtually every successful system incorporates some form of temperature control to stabilize sealer viscosity.Note de contenu : - Fig. 1.

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 : Liquid gasketing sealants have beenused for many years in automotive engineering as an alternative to solid gaskets. For instance, gasketing products suitable for flange sealing applications are deployed in engine construction and in the drive train generally. In addition to anaerobic-curing acrylates for high-rigidity flanges, RTV silicones and - a new development - polyacrylates that likewise cure at room temperature for sealing flexible flange connections are available. Nowadays products have to satisfy both performance specifications and increasingly sustainability criteria as well. Note de contenu : - Sealing rigid flange connections
