1. Zavedenie\u00a0Tester Gelbo Flex<\/a><\/h2>\n

Tester Gelbo Flex<\/strong>\u00a0je trojstani\u010dn\u00fd\u00a0Tester odolnosti Flex<\/a>, ktor\u00fd sa pou\u017e\u00edva na hodnotenie odolnosti pru\u017en\u00fdch bari\u00e9rov\u00fdch materi\u00e1lov proti ohybu. Je to cenn\u00fd postup pri ur\u010dovan\u00ed odolnosti flexibiln\u00fdch obalov\u00fdch materi\u00e1lov vo\u010di ohybov\u00fdm dieram.<\/p>\n

Jednou z k\u013e\u00fa\u010dov\u00fdch vlastnost\u00ed pru\u017en\u00e9ho bari\u00e9rov\u00e9ho materi\u00e1lu je odolnos\u0165 vo\u010di opakovan\u00e9mu nam\u00e1haniu, ktor\u00e1 sa naz\u00fdva odolnos\u0165 vo\u010di ohybu alebo Gelboflex. Spolo\u010dnos\u0165 Intertek prev\u00e1dzkuje \u0161pecializovan\u00e9 zariadenie Gelboflex na stanovenie odolnosti proti ohybu, naz\u00fdvan\u00e9 aj tester ohybu.<\/p>\n

Gelbo Flex Tester ur\u010den\u00fd na meranie ohybnosti pru\u017en\u00fdch bari\u00e9rov\u00fdch materi\u00e1lov na\u00a0ASTM F392<\/strong>.

Testovanie Gelbo Flex<\/strong>\u00a0je ur\u010den\u00fd na vystavenie cie\u013eov\u00e9ho materi\u00e1lu \u00fanave z opakovan\u00fdch kr\u00fatiacich, kr\u010diacich a oh\u00fdbac\u00edch pohybov v kontrolovan\u00fdch podmienkach. Materi\u00e1l sa potom m\u00f4\u017ee sk\u00fama\u0165 na pr\u00edtomnos\u0165 ak\u00fdchko\u013evek ohybov\u00fdch trhl\u00edn alebo dier. Pri Gelbo teste sa obalov\u00fd materi\u00e1l opakovane kr\u00fati a drv\u00ed a potom sa vyhodnocuje, \u010di nedo\u0161lo k poru\u0161eniu ohybu. Ohybov\u00e9 p\u00f4sobenie vykon\u00e1van\u00e9 po\u010das testu pozost\u00e1va z kr\u00fatenia kombinovan\u00e9ho s horizont\u00e1lnym tlakov\u00fdm pohybom, ktor\u00fd poskytuje opakovan\u00fa z\u00e1\u0165a\u017e na testovanie odolnosti ohybu pru\u017en\u00e9ho bari\u00e9rov\u00e9ho materi\u00e1lu po\u010das cel\u00e9ho testu. Zlyhanie pri oh\u00fdban\u00ed sa zvy\u010dajne ur\u010duje na z\u00e1klade v\u00fdskytu dier alebo por\u00fach celistvosti v jednej alebo viacer\u00fdch vrstv\u00e1ch viacvrstvovej \u0161trukt\u00fary alebo na z\u00e1klade poru\u0161enia vlastnost\u00ed bari\u00e9ry. Be\u017ene pou\u017e\u00edvanou normou na testovanie ohybu Gelbo je norma ASTM F392, hoci sa m\u00f4\u017ee l\u00ed\u0161i\u0165.<\/p>\n
