Podjetje Cell Instruments, inovator na podro\u010dju re\u0161itev za presku\u0161anje materialov, s sprejetjem standardov ASTM F1921 ponosno sporo\u010da svojo zavezanost k odli\u010dnosti pri presku\u0161anju vro\u010de lepljivosti. To pomeni pomemben korak pri zagotavljanju zanesljivosti in celovitosti embala\u017ee, zlasti v hitro delujo\u010dih proizvodnih linijah.<\/p>\n\n\n\n
Standard ASTM F1921 se osredoto\u010da na ocenjevanje trdnosti toplotnih pe\u010datov, ki se oblikujejo med termoplasti\u010dnimi povr\u0161inami na pro\u017enih trakovih. To vrednotenje poteka takoj po oblikovanju tesnila, pri \u010demer je poudarjen njegov pomen, preden se ohladi na sobno temperaturo.<\/p>\n\n\n\n
Pomen v embala\u017ei VFFS (Vertical Form-Fill-Seal):<\/strong><\/h2>\n\n\n\n<\/figure>\n\n\n\n
Lastnost vro\u010de lepljivosti je pomembna pri postopkih pakiranja z navpi\u010dnim zapiranjem (VFFS), pri katerih je na voljo minimalen \u010das hlajenja. Pri pakiranju VFFS se izdelki hitro nalo\u017eijo v vre\u010dko takoj, ko se odprejo zapiralne palice. Sposobnost vro\u010dega tesnjenja, da prenese velike obremenitve, postane klju\u010dnega pomena, saj zagotavlja njegovo trdnost in varnost. To je nujno za prepre\u010devanje morebitnega razlitja izdelka ali okvare embala\u017ee. Zato je ocenjevanje in optimizacija lastnosti vro\u010dega pe\u010data klju\u010dni korak pri ohranjanju zanesljivosti in celovitosti embala\u017ee v hitrih proizvodnih linijah.<\/p>\n\n\n\n
Postopek preskusa vro\u010dega oprijema po standardu ASTM F1921:<\/strong><\/h2>\n\n\n\n<\/figure>\n\n\n\n
Pe\u010datenje vzorca:<\/strong><\/h2>\n\n\n\n
Trak z vzorcem se zapre s pritiskom z dvema plo\u0161\u010datima segrevanima \u010deljustema, pri \u010demer se upo\u0161tevajo posebni pogoji glede temperature, \u010dasa stika in pritiska.<\/p>\n\n\n\n
Odvzem vzorca:<\/strong><\/h2>\n\n\n\n
Ko se \u010deljusti enote za zapiranje odprejo, se zape\u010dateni trak samodejno umakne iz \u010deljusti, pri \u010demer se umakne po izteku dolo\u010denega \u010dasa zakasnitve, ki ga je mogo\u010de prilagoditi in celo nastaviti na ni\u010d. Umik se dose\u017ee z umikom prijemal.<\/p>\n\n\n\n<\/figure>\n\n\n\n
Merjenje sile:<\/strong><\/h2>\n\n\n\n
Ko se prijemala premikajo narazen z vnaprej dolo\u010deno hitrostjo, se zape\u010dateni vzorec razteza, dokler na koncu ne odpove. Med postopkom raztezanja tester za vro\u010de lepljenje meri silo, ki je potrebna, da se pe\u010dat ohrani, dokler ne dose\u017ee to\u010dke pretrganja.<\/p>\n\n\n\n
