Abstract

Le but du présent travail était la qualification du collage, en remplacement du brasage, des billes de centrage de force sur les poutres MilliNewton, ce qui a le potentiel d'en simplifier et fiabiliser la production. Les billes ont été collées (même sérigraphie que la brasure) avec une colle époxy, Epoxy Technology EP 354, avec des ajouts de flexibilisateur R&G, ≈10% et 20% de la résine de base. Les collages ont ensuite été testés en cisaillement, après durcissement de la colle, 150°C 10 min, et après durcissement et passage à 260°C 30 s, pour simuler l'étape de brasage. Les valeurs de résistance mécanique obtenues sont acceptables, validant le principe.

Electronic waste

Electronic waste or e-waste describes discarded electrical or electronic devices. It is also commonly known as waste electrical and electronic equipment (WEEE) or end-of-life (EOL) electronics. Used electronics which are destined for refurbishment, reuse, resale, salvage recycling through material recovery, or disposal are also considered e-waste. Informal processing of e-waste in developing countries can lead to adverse human health effects and environmental pollution.

Activated carbon

Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed (activated) to have small, low-volume pores that increase the surface area available for adsorption (which is not the same as absorption) or chemical reactions. Activation is analogous to making popcorn from dried corn kernels: popcorn is light, fluffy, and its kernels have a high surface-area-to-volume ratio. Activated is sometimes replaced by active.

Nitrous oxide

Nitrous oxide (dinitrogen oxide or dinitrogen monoxide), commonly known as laughing gas, nitrous, nitro, or nos, is a chemical compound, an oxide of nitrogen with the formula N2O. At room temperature, it is a colourless non-flammable gas, and has a slightly sweet scent and taste. At elevated temperatures, nitrous oxide is a powerful oxidiser similar to molecular oxygen. Nitrous oxide has significant medical uses, especially in surgery and dentistry, for its anaesthetic and pain-reducing effects.
