1. \u012evadas\u00a0\"Gelbo Flex\" testeris<\/a><\/h2>\n

\"Gelbo Flex\" testeris<\/strong>\u00a0yra trij\u0173 sto\u010di\u0173\u00a0Lankstus patvarumo testeris<\/a>, kuris naudojamas lanks\u010di\u0173 barjerini\u0173 med\u017eiag\u0173 atsparumo lenkimui savyb\u0117ms \u012fvertinti. Tai vertinga proced\u016bra nustatant lanks\u010di\u0173 pakavimo med\u017eiag\u0173 atsparum\u0105 lenkimui suformuotoms skyl\u0117ms.<\/p>\n

Viena i\u0161 pagrindini\u0173 lanks\u010dios barjerin\u0117s med\u017eiagos savybi\u0173 yra atsparumas pasikartojan\u010diai apkrovai, kuri vadinama atsparumu lankstumui arba \"Gelboflex\". \"Intertek\" eksploatuoja specializuot\u0105 \"Gelboflex\" atsparumui lankstumui nustatyti skirt\u0105 \u012frang\u0105, dar vadinam\u0105 lankstumo testeriu.<\/p>\n

\"Gelbo Flex\" testeris, skirtas lanks\u010dioms barjerin\u0117ms med\u017eiagoms matuoti, siekiant nustatyti j\u0173 atsparum\u0105 lenkimui.\u00a0ASTM F392<\/strong>. .\u00a0\u00a0\"Gelbo Flex\" testeris\u00a0<\/strong>tai mikroprocesoriumi valdoma sistema, kurioje u\u017eprogramuotas naudotojo valdomas i\u0161 anksto nustatytas metodas, skirtas\u00a0ASTM F392<\/strong>.<\/p>\n

\"Gelbo Flex\" bandymai<\/strong>\u00a0skirtas nuvarginti tikslin\u0119 med\u017eiag\u0105 d\u0117l pasikartojan\u010di\u0173 sukimo, gniu\u017edymo ir lankstymo judesi\u0173 kontroliuojamomis s\u0105lygomis. Tuomet med\u017eiag\u0105 galima patikrinti, ar joje n\u0117ra lenkimo \u012ftr\u016bkim\u0173 ar skylu\u010di\u0173. Atliekant Gelbo bandym\u0105, pakuot\u0117s med\u017eiaga pakartotinai sukama ir gniu\u017edoma, o paskui \u012fvertinama, ar n\u0117ra lenkimo pa\u017eeidim\u0173. Atliekant bandym\u0105 atliekamas lenkimo veiksmas, kur\u012f sudaro sukimo judesys kartu su horizontaliu gniu\u017edymo judesiu, kai per vis\u0105 bandymo laik\u0105 kartojama \u012ftampa, kad b\u016bt\u0173 patikrintas lanks\u010dios barjerin\u0117s med\u017eiagos atsparumas lenkimui. Lankstumo pa\u017eeidimas paprastai nustatomas pagal tai, ar vienoje ar daugiau daugiasluoksn\u0117s strukt\u016bros sluoksni\u0173 atsiranda skyli\u0173, ar pa\u017eeid\u017eiamas vientisumas, ar sutrinka barjero savyb\u0117s. Paprastai Gelbo lankstumo bandymams naudojamas ASTM F392 standartas, nors jis gali skirtis.<\/p>\n

Svetain\u0117\u00a0\"Gelbo Flex\" testeris<\/strong>\u00a0yra labai svarbi pakavimo med\u017eiag\u0173, ypa\u010d lanks\u010di\u0173 pl\u0117veli\u0173 ir mai\u0161eli\u0173, bandymo \u012franga. Jis atlieka\u00a0\"Gelbo Flex\" testas<\/strong>, kuri imituoja \u012ftempius ir deformacijas, kurias pakuot\u0117 gali patirti j\u0105 tvarkant, transportuojant ir sand\u0117liuojant. \u0160is bandymas padeda gamintojams \u012fvertinti med\u017eiag\u0173 ilgaam\u017ei\u0161kum\u0105 ir atsparum\u0105 lenkimui ir lankstymui, taip u\u017etikrinant, kad pakuot\u0117 gal\u0117t\u0173 veiksmingai apsaugoti turin\u012f vis\u0105 jos gyvavimo cikl\u0105. Naudojant\u00a0\"Gelbo Flex\" testeris<\/strong>, \u012fmon\u0117s gali nustatyti galimus pakuo\u010di\u0173 dizaino tr\u016bkumus ir atlikti reikiamus patobulinimus, kad padidint\u0173 produkt\u0173 saug\u0105 ir vartotoj\u0173 pasitenkinim\u0105.<\/p>\n

3. \"Gelbo Flex\" testerio bandymo principas<\/h2>\n

\"Gelbo Flex\" testeris<\/strong>\u00a0sudaro trys poros 90 mm skersmens vir\u0161utini\u0173 ir apatini\u0173 dantra\u010di\u0173. Jie i\u0161d\u0117styti 180 mm atstumu vienas nuo kito pradin\u0117je eigos pad\u0117tyje (t. y. did\u017eiausiu atstumu).<\/p>\n

Krumpliuose yra apvalios ventiliacin\u0117s angos, kad bandiniai neb\u016bt\u0173 susl\u0117gti. Bandini\u0173 atramos ant \u012ftvar\u0173 yra 13 mm plo\u010dio.<\/p>\n

Kai eiga pilna arba maksimali (A~D s\u0105lyga), apatiniai dantra\u010diai per pirmuosius 90 mm [3,5 col.] vir\u0161utini\u0173 dantra\u010di\u0173 eigos sukasi 440\u00b0 kampu. Tada vir\u0161utiniai \u012ftvarai atlieka ties\u0173 horizontal\u0173 65 mm [2,5 col.] judes\u012f, kad u\u017edarytoje pad\u0117tyje \u012ftvarai b\u016bt\u0173 25 mm atstumu vienas nuo kito. Smaigali\u0173 judesys yra abipusis, vis\u0105 cikl\u0105 sudaro judesiai \u017eemyn ir atgal.<\/p>\n

D\u0117l\u00a0dalinis lankstumas<\/strong>, pagal E s\u0105lyg\u0105 vir\u0161utiniai dantra\u010diai i\u0161 180 mm atstumo nuva\u017eiuoja tik 80 mm [3,25 col.]. I\u0161naudojama tik apie 90 % vir\u0161utini\u0173 dantra\u010di\u0173 sukimosi eigos, tod\u0117l sukimosi judesys yra 400\u00b0.<\/p>\n

Visas ciklas vyksta 45 cikl\u0173 per minut\u0119 grei\u010diu.<\/p>\n

\u012evairius lanks\u010diojo kondicionavimo lygius galima pasirinkti tiesiai i\u0161 ekrano.<\/p>\n

S\u0105lyga A - visi\u0161kas lankstymas 1 val. (t. y. 2700 cikl\u0173).<\/p>\n

S\u0105lyga B - pilnas lankstymas 20 min (t. y. 900 cikl\u0173).<\/p>\n

S\u0105lyga C - pilnas lankstymas 6 min (t. y. 270 cikl\u0173).<\/p>\n

S\u0105lyga D - visi\u0161kas lankstumas 20 cikl\u0173.<\/p>\n

S\u0105lyga E - dalinis lankstumas 20 cikl\u0173.<\/p>\n
