Title
(EN) VACUUM SYSTEMS FOR EPOXY MOUNTING OF MATERIAL SAMPLES
(FR) SYSTÈMES SOUS VIDE POUR LE MONTAGE ÉPOXY D'ÉCHANTILLONS DE MATÉRIAU
Abstract
(EN)
Vacuum systems for epoxy mounting of material samples are disclosed. In some examples, a vacuum system may be a castable and/or cold mounting vacuum system that facilitates mounting and/or encapsulation of material samples in epoxy resin under low, vacuum, and/or near vacuum pressure. In some examples, the vacuum system may comprise a flow control device configured to control epoxy flow through a dispensing tube that connects to a hollow vacuum chamber. In some examples, the vacuum chamber may have an opening encircled by a rim sandwiched between upper and lower portions of a sealing ring. A movable lid may be configured to press down on the upper portion of the sealing ring when in a closed position, so as to seal the opening.
(FR)
L'invention concerne des systèmes sous vide pour le montage d'échantillons de matériaux. Dans certains exemples, un système sous vide peut être un système sous vide à montage coulable et/ou à froid qui facilite le montage et/ou l'encapsulation d'échantillons de matériau dans une résine époxy dans des conditions de dépression, de vide et/ou de pression proche du vide. Dans certains exemples, le système sous vide peut comprendre un dispositif de commande d'écoulement configuré pour commander un écoulement d'époxy à travers un tube de distribution qui se raccorde à une chambre à vide creuse. Dans certains exemples, la chambre à vide peut avoir une ouverture encerclée par un rebord pris en sandwich entre des parties supérieure et inférieure d'un anneau d'étanchéité. Un couvercle mobile peut être configuré pour appuyer sur la partie supérieure de la bague d'étanchéité lorsqu'il est dans une position fermée, de façon à sceller l'ouverture.
