Filime ya coextrusion
Kubijyanye ninganda zimenyekanisha, amagambo yatanzwe, MOQs, gutanga, ingero zubusa, igishushanyo mbonera, uburyo bwo kwishyura, serivisi nyuma yo kugurisha nibindi. Nyamuneka kanda ibibazo kugirango ubone ibisubizo byose ukeneye kumenya.
Kanda ibibazoQingdao Advanmatch Gupakira ibintu byinshi-bifatanyijemo firime igizwe muri rusangeurwego shingiro, urwego rukora hamwe nurufatiro ukurikije imikorere ya buri cyiciro cya firime utitaye kumubare wabyo.
Urufatiro: Mubisanzwe, ibice byimbere ninyuma bya firime ikomatanya igomba kuba ifite imiterere myiza yumubiri nubukanishi, kubumba no gutunganya hamwe nubushuhe bwa termal.Ifite ubushyuhe bwiza bwo gufunga no gukora ubushyuhe bwo gusudira hamwe nigiciro gito ugereranije.Hagati aho, ifite kandi inkunga nziza yo kugumana no kugumana kurwego rwimikorere nigipimo kinini murwego rwo hejuru rugena ubukana muri rusange.Ibikoresho fatizo ni PE, PP, EVA, PET na PS.
Urwego rukora:Coextrusion ikora ya firime yo gupakira ahanini ni barrière, muri rusange ni hagati ya firime nyinshi.Ikoresha cyane cyane inzitizi nka EVOH, PVDC, PVA, PA, PET, nibindi. Muri byo, ibikoresho bikoreshwa cyane kuri bariyeri ni EVOH na PVDC, kandi PA na PET isanzwe ifite imiterere ya bariyeri, yibikoresho byo hagati .
EVOH
Ethylene-vinyl alcool copolymer nubwoko bwibikoresho bya polymer bihuza imikorere ya polymer etylene na bariyeri ya gaze ya polotike ya Ethylene.Irasobanutse cyane kandi ifite gloss nziza.EVOH ifite inzitizi nziza yo kurwanya gaze na peteroli.Imbaraga za mashini, guhindagurika, kwambara birwanya, kurwanya ubukonje nimbaraga zo hejuru nibyiza kandi bifite imikorere myiza yo gutunganya.Inzitizi ya barrière ya EVOH biterwa nibiri muri Ethylene.Ibicuruzwa byuzuye ibikoresho bya EVOH birimo ibintu byiza, ibikomoka ku mata, ibikomoka ku nyama, ibicuruzwa bya foromaje, nibindi.
PVDC
Polyvinylidene chloride ni polymer ya vinylidene chloride (1,1-dichloroethylene).Ubushyuhe bwangirika bwa homopolymer polyvinylidene chloride iri munsi y aho yashonga, kuburyo bigoye gushonga.Kubwibyo, PVDC nkibikoresho byo gupakira ni copolymer ya vinylidene chloride na vinyl chloride ifite gaze nziza ya gaze, irwanya ruswa, icapiro ryiza nibiranga ubushyuhe.Mu ntangiriro, yakoreshwaga cyane cyane mu gupakira ibikoresho bya gisirikare.Ariko yatangiye gukoreshwa nka firime yo kubungabunga ibiryo muri 1950.By'umwihariko gukonjesha vuba no kubika ibintu bishya byatejwe imbere ku bwinshi hamwe no kwihutisha ikoranabuhanga rigezweho no kwihuta mu mibereho y’abantu ba none, impinduramatwara y’abateka microwave no kwagura ubuzima bwibiryo bwibiryo nubuvuzi byatumye u Porogaramu ya PVDC ikunzwe cyane.PVDC irashobora gukorwa muri firime yoroheje cyane, bityo bikagabanya umubare wibikoresho fatizo nigiciro cyo gupakira, Biracyatsinze muri iki gihe.
Igice gifatika
Bitewe nubusembwa bubi bwibintu bimwe na bimwe byashingiweho, birakenewe ko dushyira ibice bimwe bifatanye hagati yibi byiciro byombi kugirango bikine uruhare rwa kole, kugirango dukore firime "ihuriweho".Igice gifatika gikoresha resinifike, gikunze gukoreshwa ni anhydride yumugabo yashizwemo polyolefin na Ethylene-vinyl acetate copolymer (EVA).
Ibice byinshi bifatanyijemo biranga firime:
1. Umutungo munini wa barrière: Gukoresha polymer nyinshi aho gukoresha polymerisation ya monolayeri birashobora guteza imbere cyane inzitizi ya firime kandi bikagera ku ngaruka zikomeye za ogisijeni, amazi, dioxyde de carbone, impumuro, nibindi cyane cyane iyo hatoranijwe EVOH na PVDC nkuko ibikoresho bya barrière, kwanduza umwuka wa ogisijeni no kohereza imyuka y'amazi biragaragara ko ari bike cyane.
2. Imikorere ikomeye: Bitewe no guhitamo kwinshi kwa firime nyinshi mugukoresha ibikoresho, resin zitandukanye zirashobora gutoranywa ukurikije ikoreshwa ryibikoresho byingirakamaro byerekana neza imikorere yinzego zitandukanye, kugirango uzamure imikorere ya co -imashusho ya firime, nko kurwanya amavuta, kurwanya ubushuhe, kurwanya ubushyuhe bwo guteka, ubushyuhe buke bwo gukonjesha.Irashobora gukoreshwa mugupakira vacuum, gupakira sterile no gupakira.
3. Igiciro gito: Ugereranije no gupakira ibirahuri, gupakira aluminiyumu nibindi bikoresho bya pulasitike birashobora kugera ku ngaruka zimwe.Mugihe kimwe, firime ifatanije ifite ibyiza byinshi mubiciro.Kurugero, kugirango tugere ku ngaruka imwe, inzitizi ndwi zifatanije-zirindwi zifite inyungu nyinshi mugiciro kuruta firime eshanu zifatanije.Bitewe no guhimba byoroshye, igiciro cyibicuruzwa bya firime byakozwe birashobora kugabanukaho 10-20% ugereranije nigiciro cya firime yumye hamwe nizindi firime.
4. Igishushanyo mbonera cyimiterere: kwemeza imiterere itandukanye kugirango wuzuze ibisabwa byubwiza bwibicuruzwa bitandukanye.
