1. Filime imwe
Irasabwa kuba mucyo, idafite uburozi, idashobora kwinjizwa, hamwe no gukora imifuka myiza ifunga ubushyuhe, ubushyuhe nubukonje, imbaraga za mashini, kurwanya amavuta, kurwanya imiti, no kurwanya.
2. Umufuka wa aluminium
99.5% ya aluminiyumu yuzuye ya electrolytike irashonga hanyuma igashyirwa muri fayili na kalendari, bikaba byiza nka substrate yo gupakira ibintu byoroshye.
3. Vacuum evaporation firime ya aluminium
Munsi ya vacuum, ibyuma bitetse cyane, nka aluminium, bishonga kandi bigahinduka umwuka hanyuma bigashyirwa kuri firime ya plastike ku ngoma ikonje kugirango ikore firime ya aluminiyumu ifite urumuri rwiza.
4. Ipitingi ya Silicon
Ibikoresho byo gupakira mu mucyo bifite inzitizi ndende cyane byakozwe mu myaka ya za 1980, bizwi kandi ko ari ceramic coating.
5. Fata (yumye / itose) firime ikomatanya
Filime ya Monolayer ifite ibyiza bimwe nibibi byihariye.Uburyo bwa firime butose: substrate imwe yashizwemo kole hanyuma igashyirwa hamwe nindi firime ya substrate, hanyuma ikuma igakira.Niba ari ibintu bidafite isuku, gukama kole birashobora kuba bibi kandi ubwiza bwibibumbano bikagabanuka.Uburyo bwumye bwo kumisha: Kwambika ibifatika kuri substrate, reka ibanze byumye mbere, hanyuma ukande hanyuma ube laminate kugirango uhuze firime za substrate zitandukanye.
6. Gukuramo ibishishwa bya firime
Kuri extruder, thermoplastique iterwa muri T-gupfa ku mpapuro, file, substrate ya plastike kugirango itwikwe, cyangwa ibisigazwa bisohoka bikoreshwa nkumuhuza hagati, naho ubundi filime ya firime irashyushye.Ibikoresho bikanda hamwe kugirango bikore firime "sandwich".
7. Coextrusion igizwe na firime
Ukoresheje extruders ebyiri cyangwa eshatu, gusangira ibice bipfa, bihinduranya hagati ya thermoplastique ihuza byinshi kugirango ikore firime nyinshi cyangwa impapuro.
8. Filime ndende
Yerekeza ku bikoresho bifite uburebure bwa 25.4 mm mu bihe bya 23 ° C na RH65%, umuvuduko wa ogisijeni uri munsi ya 5ml / m2· D, kandi igipimo cyo kohereza amazi kiri munsi ya 2g / m2· D.
9. Kubika neza no gufata firime
Imyuka ya Ethylene adsorption membrane, wongeyeho zeolite, cristobalite, silika nibindi bintu muri membrane birashobora gukuramo gaze ya Ethylene ihumeka n'imbuto n'imboga kandi bikabuza kwera vuba.
Kurwanya anti-condensation na fogge, hejuru yimbere ya firime ipakira imbuto zicyatsi zifite kondegene nyinshi hamwe nigihu, byoroshye gutera uburibwe kubiryo.
Filime ya Antibacterial, wongeyeho zeolite ya syntetique (SiO2+ Al2O3) hamwe nibikorwa byo guhana ion mubikoresho bya pulasitiki, hanyuma ukongeramo inorganic yuzuza irimo ifeza ion, ifeza ya sodium ya sodium ihinduka feza zeolite, kandi ubuso bwayo bufite antibacterial.
Filime-ya-infrarafarike yo kubika neza ivanze na ceramic yuzuza muri firime ya plastike, kuburyo firime ifite umurimo wo kubyara imirasire ya-infragre-kure, idashobora guhagarika gusa, ahubwo ikora na selile ziri mu mbuto rwatsi, bityo ifite umurimo wo kubungabunga agashya.
10. Firime yo gupakira
Ahanini ikoreshwa mugukora ibicuruzwa bya aseptic byibiryo nubuvuzi, birasabwa kugira: kurwanya sterisizione;inzitizi ndende n'imbaraga;ubushyuhe bwiza no kurwanya ubukonje (-20 ℃ ntibigabanuka);Kurwanya inshinge no kurwanya kunama neza;Igishushanyo cyacapwe ntikizangirika mubushyuhe bwo hejuru cyangwa ubundi buryo bwo kuboneza urubyaro.
11. Isakoshi yo guteka irwanya ubushyuhe bwinshi
Mu myaka ya za 1960, Ikigo cy’ubushakashatsi bw’amato muri Amerika cyabanje guteza imbere no kugikoresha mu biribwa byo mu kirere.Nyuma yibyo, Ubuyapani bwahise butera imbere kandi butera imbere kandi bushyira mu bikorwa ubwoko bushya bwibiryo byoroshye.Imifuka yo guteka yubushyuhe bwo hejuru irashobora kugabanwa muburyo buboneye (hamwe nubuzima bwigihe kirenze umwaka umwe) nubwoko butagaragara (hamwe nubuzima bwimyaka irenga ibiri), ubwoko bwa bariyeri nyinshi nubwoko busanzwe.Ukurikije ubushyuhe bwa sterilisation, igabanijwemo igikapu cyo guteka ubushyuhe buke (100 ℃, 30min), igikapu cyo guteka cyo hagati (121 ℃, 30min), igikapu cyo guteka ubushyuhe bwinshi (135 ℃, 30min).Ibikoresho by'imbere by'isakoshi ya retort bikozwe muri firime zitandukanye kandi zuzuye PE (LDPE, HDPE, MPE), firime irwanya ubushyuhe bwinshi CPP cyangwa IPP yuzuye, nibindi.
Ibyiza byingenzi byubushyuhe bwo guteka:
Guteka ubushyuhe bukabije birashobora kwica bagiteri zose, 121 ℃ / 30min irashobora kwica bagiteri zose za botuline;
TBishobora kubikwa ku bushyuhe bwicyumba igihe kirekire nta firigo, kandi birashobora kuribwa imbeho cyangwa ubushyuhe;
Ibikoresho byo gupakira bifite inzitizi nziza, ntibiri munsi y'ibiryo byafunzwe;
Kureka gucapa, gucapa neza no gushushanya;
Imyanda iroroshye gutwikwa.
12. Firime yo gupakira ubushyuhe bwinshi
Ingingo yo gushonga yibikoresho iri hejuru ya 200 ° C, ikwiranye nimbaraga nyinshi zikomeye / ibikoresho byoroshye.
13. Firime yangiritse
Ibicuruzwa bya pulasitiki byangirika birashobora kugabanywa mu gufotora, kubora ibinyabuzima, gufotora no kubinyabuzima ukurikije uburyo bwo kubora.
14. Shyushya firime
Ibikoresho ni PP, CV uburyo bwo kurambura-gupfa, cyangwa uburyo bwa calendering, cyangwa solvent Uburyo bwo gukina bukora kurambura icyerekezo, kandi molekile irambuye ikonjeshwa munsi yikirahure cyikirahure igafunga.
