Ultra-high barrière gahunda yo gushyira mubikorwa ibikoresho bisubirwamo

Ibikoresho byongera gukoreshwa byongeye gukoreshwa mumasoko yo gupakira imbere. Nyamara, porogaramu nyinshi ziracyibanda mubice bimwe na bito byo hagati. Nigute washyira mubikorwa ibikoresho bisubirwamo byongeye gukoreshwa murwego rwo hejuru rwa bariyeri cyangwa se umurima muremure wo guteka ubushyuhe bwinshi? Kugeza ubu, ibigo bimwe mubisanzwe bitanga ibikoresho bimwe, byaba byujuje ibisabwa kugirango bisubirwemo? Ubwa mbere, ni ubuhe buryo bushobora gukoreshwa muburyo bumwe? Nubwo ibikoresho bimwe bisubirwamo byongeye gukoreshwa byamamaye cyane ku isoko ryimbere mu gihugu, ariko ibigo bimwe na bimwe bitanga imiterere yibikoresho mu cyemezo gisubirwamo, ntibizagira ijanisha ryinshi ryikigereranyo. Igishushanyo cya 1 cyerekana amakuru yikizamini cyo kugarura igipimo cyo gupakira ibintu byatanzwe na “Institute Cyclos-HTP Institute of Germany”, ni isosiyete yigenga isuzuma kandi itanga impamyabumenyi. Kugeza ubu, yatanze ibihumbi icumi byicyemezo cyo gutunganya ibicuruzwa ku isi. Mu Bushinwa, ibigo byinshi nka Huizhou Baoba na Daoco nabyo byabonye ibyemezo byatanzwe n'iki kigo. Ibyo gukira ni ibisubizo byikizamini cyibicuruzwa bipfunyitse bifite imiterere rusange ihuye nuburyo bwibintu bimwe. Kuki hariho itandukaniro rinini?
Ukurikije umurongo ngenderwaho w’ibihugu by’i Burayi CEFLEX hamwe n’amakuru y’Ikigo Cyclos-HTP mu Budage, igipimo cyo kugarura ibikoresho by’isuku ryinshi ni ibi bikurikira: firime imwe ya polypropilene (PP), firime imwe ya polyethylene (PE) hamwe na firime imwe ya polyester (PET) ifite igipimo kinini cyo gukira: Ibikoresho byinshi byo kugarura ibintu bya polyolefin bitarimo ibikoresho bya aluminium, PVD, PVD; kole, isahani ya aluminium, EVOH, nibindi) byose ntibirenze 5%. Yemerewe kubamo ibiyigize, nibirimo byose, ntabwo bitandukanijwe nibirimo, aribintu byinshi byashushanyijeho imishinga yibicuruzwa bikunda kwibeshya, bikavamo igipimo gito cyo gukira mugihe cyemewe.
Imyuka ya Vacuum irashobora kunoza imikorere yinzitizi zibiri zamazi yo kurwanya amazi na ogisijeni, nuburyo bwo kunoza imikorere ya bariyeri ndende muri iki gihe, hamwe nuburyo bukoreshwa cyane nigikorwa cyo kurwanya amazi na ogisijeni. Imyuka ya Vacuum nimwe mubikorwa hamwe nigice gito cyibikoresho bitari ngombwa mubikorwa byose byo guterura inzitizi. Umubyimba wububiko bwa aluminiyumu ni 0.02 ~ 0.03u ​​gusa, ufite igipimo gito cyane kandi ntabwo bigira ingaruka kumahame yo gusubiramo no gukoreshwa. Hashingiwe ko ishobora gukoreshwa, uburyo bukoreshwa cyane ni uburyo bwa PVA, bushobora kunoza imikorere ya ogisijeni. Ubunini bwibikorwa byo gutwikira ni nka 1 ~ 3u, bingana umubare muto ugereranije. Kubijyanye n'imikorere yo kurwanya ogisijeni, ni inzira ihendutse, ihuza n'ihame ryo kongera gukoreshwa no gukoreshwa. Ariko PVA ifite intege nke ebyiri zigaragara: icya mbere, ntacyo ikora ngo ihagarike amazi; Icya kabiri, biroroshye gutakaza imikorere yo kurwanya ogisijeni nyuma yo gufata amazi. Hashingiwe ko ishobora gukoreshwa, inzira ikoreshwa cyane hamwe nogusohora ni EVOH gufatanya muri iki gihe, mugihe PA ikoreshwa cyane ntabwo ihuye nihame risubirwamo. Mu ihame risubirwamo, PA irabujijwe, kandi igipimo ntarengwa cya EVOH ntabwo kirenze 5%. Ubunini bwa EVOH gufatanya ni hafi 4 ~ 9u, ukurikije ubunini bwibikoresho byingenzi biratandukanye, gahunda yo gufatanya na EVOH iroroshye kurenga 5% yikigereranyo, cyane cyane mububyimbye rusange bwimiterere yoroheje, kandi inzitizi yayo nayo ifitanye isano itaziguye nubunini. Ihame ryo gusubiramo ibintu, EVOH igarukira ku kigereranyo cyiyongereye kandi ifite iterambere rito kuri bariyeri. Kimwe na PVA, EVOH itezimbere gusa okisijene kandi ntabwo ifasha kurwanya amazi. Ukurikije tekinoroji rusange ikuze muri iki gihe, firime ya BOPP na PET irashobora kugera ku kurwanya neza amazi na ogisijeni. Bolene firime inzitizi ndende ya BOPP ya aluminiyumu, inzitizi ebyiri munsi ya 0.1; Kugeza ubu, hari tekinoroji ikuze yo gukoresha inzira eshatu cyangwa ebyiri kuri bariyeri kuri firime yoroheje icyarimwe, hamwe ninyungu zuzuzanya, kugirango tugere ku mikorere myiza ya bariyeri. Ukurikije ikoranabuhanga rigezweho, imbonerahamwe ikurikira irerekana urutonde rwinzitizi ziranga ibintu nyamukuru byongera gukoreshwa, hamwe nigipimo gishoboka cyo gukira kwa buri nyubako hamwe nibisabwa hamwe nibyiza byinshi.
