Mesure optique par laser<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">D\u00e8s leur sortie du four de recuit, les bouteilles passent par des postes d'inspection optique \u00e0 grande vitesse. Des lasers mesurent le diam\u00e8tre ext\u00e9rieur du filetage, le diam\u00e8tre int\u00e9rieur du col, la hauteur totale et la verticalit\u00e9 du r\u00e9cipient. Tout r\u00e9cipient pr\u00e9sentant un \u00e9cart sup\u00e9rieur \u00e0 \u00b10,2 mm par rapport au plan technique est automatiquement rejet\u00e9 par des jets d'air.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Essai de d\u00e9compression \u00e0 haute pression<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Les \u00e9chantillons sont soumis \u00e0 des essais de pression interne pouvant atteindre 0,6 MPa. Cet essai permet de v\u00e9rifier que la matrice en verre ne contient aucune bulle d'air cach\u00e9e, aucun corps \u00e9tranger ni aucune microfissure susceptible de provoquer une d\u00e9faillance structurelle catastrophique lorsque le m\u00e9canisme de la pompe est comprim\u00e9 ou bouch\u00e9.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Essais de r\u00e9gularit\u00e9 de l'\u00e9vacuation et d'endurance de l'actionnement<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Des pompes s\u00e9lectionn\u00e9es au hasard sont mont\u00e9es sur des r\u00e9cipients remplis et plac\u00e9es dans des bancs d'essai \u00e0 actionnement m\u00e9canis\u00e9. Ces machines actionnent m\u00e9caniquement les actionneurs jusqu'\u00e0 5 000 cycles \u00e0 une fr\u00e9quence contr\u00f4l\u00e9e. Le jet est enregistr\u00e9 \u00e0 l'aide de cam\u00e9ras haute vitesse afin de v\u00e9rifier que l'angle d'atomisation et le volume de dosage (par exemple, 0,07 ml par course) restent parfaitement constants tout au long de la dur\u00e9e de vie du r\u00e9cipient.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Foire aux questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Pourquoi la pompe de mon parfum crachote-t-elle ou cesse-t-elle de vaporiser alors que le flacon est encore \u00e0 moiti\u00e9 plein ?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Un ph\u00e9nom\u00e8ne de \u00ab sputtering \u00bb ou une d\u00e9faillance pr\u00e9matur\u00e9e de l'\u00e9vacuation se produit lorsque de l'air p\u00e9n\u00e8tre dans la chambre de la pompe par un raccord mal serr\u00e9 ou lorsque le tube plongeur se d\u00e9place de sa position initiale. Si le tube plongeur est trop rigide ou coup\u00e9 \u00e0 un angle inappropri\u00e9, il peut s'enrouler vers le haut et aspirer depuis la poche d'air situ\u00e9e au-dessus du niveau du liquide plut\u00f4t que depuis le fond du r\u00e9cipient. Ce probl\u00e8me peut \u00eatre r\u00e9solu en utilisant des tubes plongeurs d\u00e9coup\u00e9s avec pr\u00e9cision et dont la m\u00e9moire du mat\u00e9riau a \u00e9t\u00e9 calibr\u00e9e avec exactitude, afin de garantir qu'ils atteignent syst\u00e9matiquement le point le plus bas du r\u00e9cipient.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Pourquoi un flacon de parfum fuit-il au niveau de la base du col pendant le transport ?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Les fuites \u00e0 la base du col sont g\u00e9n\u00e9ralement dues \u00e0 un d\u00e9calage entre les tol\u00e9rances de finition du col de la bouteille en verre et celles du joint d'\u00e9tanch\u00e9it\u00e9 de la pompe. Lors des variations de temp\u00e9rature, la pression interne pousse le produit \u00e0 passer au-del\u00e0 du joint mal ajust\u00e9. L'utilisation de verre moul\u00e9 de qualit\u00e9 sup\u00e9rieure avec des surfaces sup\u00e9rieures planes, associ\u00e9 \u00e0 des joints en PTFE haute densit\u00e9 ou en Viton, garantit une \u00e9tanch\u00e9it\u00e9 continue et r\u00e9sistante \u00e0 la vapeur qui r\u00e9siste \u00e0 la d\u00e9formation sous pression.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Est-ce que tous les flacons de parfum en verre peuvent \u00eatre rechargeables ?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Tous les r\u00e9cipients en verre ne se pr\u00eatent pas au remplissage. Les mod\u00e8les traditionnels sont \u00e9quip\u00e9s d'un bouchon \u00e0 sertir qui n\u00e9cessite une d\u00e9formation m\u00e9canique permanente d'une virole en aluminium, laquelle ne peut \u00eatre retir\u00e9e sans endommager l'ensemble de la pompe. Pour cr\u00e9er un \u00e9cosyst\u00e8me de recharge efficace, la bouteille doit \u00eatre con\u00e7ue avec un filetage de haute pr\u00e9cision (tel que les finitions FEA 15 ou GPI) qui conserve son int\u00e9grit\u00e9 structurelle et sa capacit\u00e9 d'\u00e9tanch\u00e9it\u00e9 au fil de multiples cycles d'ouverture et de fermeture.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">En quoi la qualit\u00e9 du verre influe-t-elle sur la stabilit\u00e9 et la dur\u00e9e de conservation d'un parfum ?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Un verre de qualit\u00e9 inf\u00e9rieure \u00e0 forte teneur en alcalins peut se d\u00e9laminer lorsqu'il est expos\u00e9 \u00e0 la forte concentration d'alcool et d'\u00e9l\u00e9ments acides pr\u00e9sents dans les parfums, ce qui provoque la formation de particules microscopiques qui se d\u00e9tachent dans le liquide. Ces particules obstruent rapidement les composants internes d\u00e9licats du diffuseur \u00e0 brume fine. L'utilisation d'un verre de haute puret\u00e9, dont la teneur en dioxyde de silicium a \u00e9t\u00e9 optimis\u00e9e, garantit un int\u00e9rieur chimiquement inerte qui pr\u00e9serve le profil olfactif d'origine et prot\u00e8ge la pompe m\u00e9canique contre le colmatage.<\/p>","protected":false},"excerpt":{"rendered":"<p>Selecting the right container for a premium fragrance goes far beyond aesthetic appeal.
