<\/a><\/figure>\n\n\n\nVad \u00e4r hydrolytisk best\u00e4ndighet?<\/h2>\n\n\n\n
Med hydrolytisk best\u00e4ndighet avses glasets f\u00f6rm\u00e5ga att motst\u00e5 kemisk nedbrytning vid kontakt med vatten, s\u00e4rskilt n\u00e4r det upphettas till vissa temperaturer. Glasbeh\u00e5llare som anv\u00e4nds inom l\u00e4kemedels- eller livsmedelsindustrin m\u00e5ste klara tester av hydrolytisk best\u00e4ndighet f\u00f6r att bekr\u00e4fta att de inte avger skadliga \u00e4mnen n\u00e4r de uts\u00e4tts f\u00f6r vatten under en l\u00e4ngre tid.<\/p>\n\n\n\n
ISO 719: Hydrolytisk best\u00e4ndighet hos glaskorn vid 98 \u00b0C<\/h2>\n\n\n\n
ISO 719 \u00e4r den standard som fastst\u00e4ller metoden f\u00f6r provning av glaskornens hydrolytiska best\u00e4ndighet vid 98 \u00b0C<\/strong>. Denna metod \u00e4r idealisk f\u00f6r att testa glas med l\u00e4gre best\u00e4ndighet, s\u00e5som natriumkalciumglas. Testet g\u00e5r ut p\u00e5 att extrahera glaskorn (av en viss storlek) med destillerat vatten vid 98 \u00b0C under 60 minuter, varefter utsl\u00e4ppet av alkaliska joner (fr\u00e4mst natrium) fr\u00e5n glaset analyseras.<\/p>\n\n\n\n Resultaten anv\u00e4nds f\u00f6r att klassificera glaset utifr\u00e5n dess hydrolytiska best\u00e4ndighet. Glas med h\u00f6gre best\u00e4ndighet, s\u00e5som borosilikatglas, kan kr\u00e4va en annan provningsmetod, enligt vad som anges i ISO 720.<\/p>\n\n\n\n ISO 720 \u00e4r en liknande provningsmetod, men den utf\u00f6rs vid en h\u00f6gre temperatur p\u00e5 121 \u00b0C<\/strong>. Detta test \u00e4r b\u00e4ttre l\u00e4mpat f\u00f6r slitstarka glastyper<\/strong>, till exempel borosilikatglas, som ofta anv\u00e4nds i medicinska och farmaceutiska f\u00f6rpackningar tack vare sin h\u00e5llbarhet. F\u00f6rfarandet inneb\u00e4r en liknande extraktionsprocess, men skiljer sig \u00e5t vad g\u00e4ller temperatur, varaktighet och volymen p\u00e5 det glas som testas.<\/p>\n\n\n\n Testning av hydrolytisk best\u00e4ndighet \u00e4r viktig eftersom den hj\u00e4lper tillverkare och kvalitetsansvariga att s\u00e4kerst\u00e4lla att det glas som anv\u00e4nds i f\u00f6rpackningarna inte reagerar med inneh\u00e5llet. Eventuell nedbrytning kan potentiellt \u00e4ventyra l\u00e4kemedels eller livsmedels integritet, vilket kan leda till s\u00e4kerhetsrisker och problem med myndighetskrav.<\/p>\n\n\n\n Standardutrustningen f\u00f6r provning av hydrolytisk best\u00e4ndighet omfattar v\u00e5gar, byretter, pipetter och s\u00e4rskilda glasredskap, d\u00e4ribland autoklaver, f\u00f6r att uppr\u00e4tth\u00e5lla de exakta f\u00f6rh\u00e5llanden som kr\u00e4vs f\u00f6r korrekta resultat. Instrument som Cell Instruments glasbaserade kornprovtagare GHR-01A<\/strong> \u00e4r utformade f\u00f6r att uppfylla dessa standarder och s\u00e4kerst\u00e4lla korrekt hantering av glasproverna under provningen.<\/p>\n\n\n\n Den test av hydrolytisk best\u00e4ndighet f\u00f6r glasbeh\u00e5llare<\/strong> \u00e4r en viktig metod f\u00f6r att fastst\u00e4lla glasets kemiska best\u00e4ndighet. Genom att s\u00e4tta sig in i standarderna ISO 719 och ISO 720 kan tillverkarna s\u00e4kerst\u00e4lla att deras produkter \u00e4r s\u00e4kra och uppfyller branschens f\u00f6reskrifter. Genom att anv\u00e4nda tillf\u00f6rlitlig testutrustning, s\u00e5som Cell Instruments glasbaserade kornprovtagare GHR-01A<\/strong>, kan f\u00f6retagen uppr\u00e4tth\u00e5lla kvaliteten och integriteten hos sina glasf\u00f6rpackningsmaterial.<\/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.
