Title (EN) PROCESS TO MITIGATE UNWANTED FORMATION OF POPCORN POLYMERS USING ACOUSTIC EMISSION SIGNALS
(FR) PROCÉDÉ D’ATTÉNUATION DE LA FORMATION INDÉSIRABLE DE POLYMÈRES DE TYPE POPCORN AU MOYEN DE SIGNAUX D’ÉMISSION ACOUSTIQUES
Abstract:
(EN) Process to monitor unwanted formation of a polymer, having internal mechanical strain, wherein said formation of polymer generates acoustic emissions due to the sudden 5 break of the polymer, wherein the number of said acoustic emissions increases over time when there is formation of said unwanted polymer formation, wherein said acoustic emissions is detected by a resonant piezo electric transducer having a resonant frequency centred on the second harmonic of said acoustic emission.
(FR) La présente invention concerne un procédé de surveillance de la formation indésirable d’un polymère, présentant une contrainte mécanique interne, ladite formation de polymère générant des émissions acoustiques dues à la rupture soudaine du polymère, le nombres desdites émissions acoustiques augmentant au cours du temps lorsqu’il existe une formation de ladite formation de polymère indésirable, lesdites émissions acoustiques étant détectées par un transducteur piézoélectrique résonant ayant une fréquence résonante centrée sur la deuxième harmonique de ladite émission acoustique.
