<\/a><\/figure>\n\n\n\nQu'est-ce que la r\u00e9sistance \u00e0 l'hydrolyse ?<\/h2>\n\n\n\n
La r\u00e9sistance \u00e0 l'hydrolyse d\u00e9signe la capacit\u00e9 du verre \u00e0 r\u00e9sister aux agressions chimiques lorsqu'il est en contact avec l'eau, en particulier lorsqu'il est chauff\u00e9 \u00e0 certaines temp\u00e9ratures. Les r\u00e9cipients en verre utilis\u00e9s dans les secteurs m\u00e9dical ou alimentaire doivent passer des tests de r\u00e9sistance \u00e0 l'hydrolyse afin de v\u00e9rifier qu'ils ne lib\u00e8rent pas de substances nocives lorsqu'ils sont expos\u00e9s \u00e0 l'eau sur une longue p\u00e9riode.<\/p>\n\n\n\n
ISO 719 : R\u00e9sistance \u00e0 l'hydrolyse des grains de verre \u00e0 98 \u00b0C<\/h2>\n\n\n\n
La norme ISO 719 d\u00e9finit la m\u00e9thode d'essai de la r\u00e9sistance \u00e0 l'hydrolyse des grains de verre \u00e0 98 \u00b0C<\/strong>. Cette m\u00e9thode est id\u00e9ale pour tester les verres moins r\u00e9sistants, tels que le verre sodocalcique. L'essai consiste \u00e0 extraire des grains de verre (d'une taille sp\u00e9cifique) avec de l'eau distill\u00e9e \u00e0 98 \u00b0C pendant 60 minutes, puis \u00e0 analyser la lib\u00e9ration d'ions alcalins (principalement du sodium) par le verre.<\/p>\n\n\n\n Les r\u00e9sultats permettent de classer le verre en fonction de sa r\u00e9sistance \u00e0 l'hydrolyse. Les verres pr\u00e9sentant une r\u00e9sistance plus \u00e9lev\u00e9e, tels que le borosilicate, peuvent n\u00e9cessiter une m\u00e9thode d'essai diff\u00e9rente, comme le pr\u00e9cise la norme ISO 720.<\/p>\n\n\n\n La norme ISO 720 est une m\u00e9thode d'essai similaire, mais r\u00e9alis\u00e9e \u00e0 une temp\u00e9rature plus \u00e9lev\u00e9e de 121 \u00b0C<\/strong>. Ce test est plus adapt\u00e9 \u00e0 types de verre r\u00e9sistant<\/strong>, comme le verre borosilicat\u00e9, souvent utilis\u00e9 dans les emballages m\u00e9dicaux et pharmaceutiques en raison de sa r\u00e9sistance. La proc\u00e9dure suit un processus d'extraction similaire, mais elle diff\u00e8re par la temp\u00e9rature, la dur\u00e9e et le volume de verre test\u00e9.<\/p>\n\n\n\n Les essais de r\u00e9sistance \u00e0 l'hydrolyse sont importants car ils permettent aux fabricants et aux professionnels du contr\u00f4le qualit\u00e9 de s'assurer que le verre utilis\u00e9 dans les emballages n'interagit pas avec leur contenu. Toute d\u00e9gradation pourrait compromettre l'int\u00e9grit\u00e9 des produits pharmaceutiques ou alimentaires, ce qui soul\u00e8verait des probl\u00e8mes de s\u00e9curit\u00e9 et des questions d'ordre r\u00e9glementaire.<\/p>\n\n\n\n Le dispositif d'essai standard pour la r\u00e9sistance \u00e0 l'hydrolyse comprend des balances, des burettes, des pipettes et de la verrerie sp\u00e9cifique, notamment des autoclaves, afin de maintenir les conditions pr\u00e9cises requises pour obtenir des r\u00e9sultats fiables. Des instruments tels que \u00c9chantillonneur de grains en verre GHR-01A de Cell Instruments<\/strong> sont con\u00e7us pour r\u00e9pondre \u00e0 ces normes et garantir une manipulation ad\u00e9quate des \u00e9chantillons de verre pendant l'essai.<\/p>\n\n\n\n Le essai de r\u00e9sistance \u00e0 l'hydrolyse des r\u00e9cipients en verre<\/strong> Il s'agit d'une proc\u00e9dure essentielle pour d\u00e9terminer la r\u00e9sistance chimique du verre. La ma\u00eetrise des normes ISO 719 et ISO 720 permet aux fabricants de s'assurer que leurs produits sont s\u00fbrs et conformes aux r\u00e9glementations du secteur. En utilisant des \u00e9quipements d'essai fiables, tels que \u00c9chantillonneur de grains en verre GHR-01A de Cell Instruments<\/strong>, les entreprises peuvent pr\u00e9server la qualit\u00e9 et l'int\u00e9grit\u00e9 de leurs emballages en verre.<\/p>\n\n\n\n <\/p>","protected":false},"excerpt":{"rendered":" Introduction to Hydrolytic Resistance Testing for Glass Containers The hydrolytic resistance test for glass containers is a crucial evaluation used to determine the chemical durability of glass when exposed to water or aqueous solutions.
