Ni irihe tandukaniro riri hagati yuburyo butatu, ibice bitanu, ibice birindwi na cyenda ya firime ya coextrusion

Ibikoresho byoroshye byo gupakira, akenshi ufite ibice bitatu, bitanu, birindwi, icyenda bya firime.Ni irihe tandukaniro riri hagati yuburyo butandukanye bwa firime?Uru rupapuro rwibanze ku isesengura, kugirango ubone ibisobanuro.

Inzitizimuburyo butanu bwububiko busanzwe buri murwego, ikabigumya mumazi yikirere.Kuberako bariyeri iri murwego rwibanze, ibindi bikoresho birashobora gukoreshwa mukuzamura cyane imikorere ya bariyeri.Nylon irashobora gukoreshwa murwego rwibanze, kugirango imiterere ya 5-layer hamwe na PE hejuru yubutaka irashobora guhangana nibikoresho byinshi bisa na firime ya PE no kunoza ubushobozi bwibikorwa.Byongeye kandi, utunganya ibintu ashobora gukoresha pigment murwego rwo hanze atagize ingaruka kumurongo uhuza cyangwa kuri bariyeri.

Filime eshatu zicyiciro, cyane cyane izikoresha nylon, zikunda kugorama kubera imiterere itandukanye yumubiri muburyo butemewe.Kuburyo bwa 5-layer, nibisanzwe gukoresha ibishushanyo cyangwa hafi yimiterere kugirango ugabanye kugabanuka.Crimp muburyo bwa 3-layer irashobora kugenzurwa gusa na nylon copolymer.Muburyo bwa 5-layer, gusa iyo processeur ishobora gukoresha nylon 6 birashoboka kubona nylon hafi kimwe cya kabiri cyubugari bwibice bitatu.Ibi bizigama ibiciro byibanze mugihe utanga inzitizi imwe kandi itunganijwe neza.

Kuri firime zo hejuru,EVOHni Byakoreshejwe Nka Inzitizi Kuri Gusimbuza Nylon.Nubwo EVOH ifite inzitizi nziza ya ogisijeni iyo yumye, izangirika vuba iyo itose.Kubwibyo, birasanzwe guhuza EVOH mubice bibiri bya PE muburyo bwa 5 kugirango wirinde ubushuhe.Mubice 7 bya EVOH, EVOH irashobora gukusanyirizwa mubice bibiri byegeranye bya PE, hanyuma bikarindwa ninyuma ya PE.Ibi bitezimbere cyane kurwanya ogisijeni muri rusange kandi bigatuma imiterere ya 7 igabanuka cyane.

Gucamo ibice cyangwa kurira nabyo birashobora kuba ikibazo kumiterere yinkuru eshanu.Iterambere ryimiterere-7 bizatuma inzitizi zikomeye zicamo ibice bibiri bisa muguhuza ibice bito.Ibi bikomeza imitungo ya barrière mugihe ituma pake irwanya kumeneka cyangwa kurira.Byongeye kandi, ibice 7 byubaka bifasha gutunganya gutanyagura igice cyo hanze kugirango ugabanye igiciro cyibikoresho fatizo.Polimeri zihenze zirashobora gukoreshwa nkibice byo hejuru, mugihe polymers ihendutse irashobora gusimbuza ibyinshi byabanjirije.

Mubisanzwe, bariyeri igice cya bariyeri ndende ifata ibice bitanu muburyo.Kubera iterambere muri polymer no gutunganya ikoranabuhanga, ijanisha ryubunini rusange bwiki gice muburyo bwose rihora rigabanuka, ariko imikorere ya barrière irakomeza.

Ariko, biracyakenewe kugumana ubunini bwa firime.Kuva kuri 7 kugeza kuri 9, abatunganya barashobora kubona imashini nziza, isura nigikorwa cyo gukora.Kuri firime ya bariyeri ndende, inyongera zinyuranye zitangwa na 7-layer cyangwa 9-umurongo wo gukuramo birashobora kuba byinshi.Igiciro cyiyongereye cyo kugura umurongo wa 7-cyangwa 9-umurongo wo gukuramo urashobora kugira igihe cyo kwishyura kitarenze umwaka ugereranije numurongo wibikorwa 5.
