Isithintelo sokuSebenza kweFoyile yeAluminiyam eDityanisiweyo yoShishino kwiPakethe yoMthamo oSolid
Ukunyaniseka kokupakishwa kwedosi eqinileyo kuxhomekeke kakhulu ekusebenzeni kwe I-Aluminium Barer Fiel, esebenza njengeendlela eziphambili zokuzikhusela ngokuchasene nokupheliswa kwendalo ngenxa yezithako ezisebenzayo ezisebenzayo (I-apis). Olu hlalutyo lujongile iimfuno zolwakhiwo kwaye uqwalasele iipropathi ezingaphezulu zeAluminiyam foils ngokuchasene nesoyikiso esibalulekileyo sokufuma kunye neoksijini.
1. Indima ebalulekileyo yezixhobo zothintelo
Ukugcina ukuzinza kweekhemikhali kunye nokusebenza kakuhle kweefom ze-Omram ye-Ones eqinileyo ye-Dosamoge kwimveliso yamachiza.
I-APIS ihlala ichaphazeleka kwi-Degraphiays, kubandakanya i-hydrolysis (ukufuma - iqhutywa) kunye ne-oxidation (Ioksijini-iqhutywa).
Ezi zinto zinyanzeliswayo zinyanzelisa izinto zokupakisha ezibonelela ngokungafanelekanga-ngokupheleleyo, imfuneko yafunyanwa ngokukhethekileyo yimingxunya esekwe i-aluminium.
2. Uyilo lolwakhiwo lwezinto ezihlanganisiweyo
Imilambo yesiqhelo yamayeza ayimigca enamachiza ayiminye imigudu yokudibanisa umsebenzi wesithintelo wensimbi kunye nokutywina kwe-polymers ye-polymers..
2.1 Isiseko esingafanelekanga
Isiseko senxalenye ye-aluminium, Ngokwesiqhelo ukusukela 20 $\mu $ m to 50 $\mu $ m ubukhulu.
I-aluminium ka-Aluminium, I-biltic ye-tiquic latrice ibhloka ngokwasemzimbeni i-valing yegesi kunye neemolekyuli zamanzi.
Le meko ye-metric licandelo elisisiseko elinoxanduva lokuphakamaI-Aluminium Barer Fielukusebenza.
2.2 Imingxunya yokusebenza yePolymer
I-aluminium Core ifakwe phakathi kwezinto zePolymeric, nganye isebenza injongo ethile.
Umaleko wangaphandle (I-E.G., OPA okanye PET) Inika amandla oomatshini kunye nokuxhathisa i-abrasion ngexesha lokuphatha.
Umaleko wangaphakathi, Rhoqo itywina lobushushu i-lacquer (Hsl) okanye i-polymer njenge-pvc, iqinisekisa i-gooust, Itywina eliphantsi lobushushu kwi-blister seb yewebhu.
3. Umsebenzi we-OXYGENT (I-OVP)
Ukuthotywa kwe-oxidative kunokunciphisa ngokukhawuleza amandla e-API kwaye kuvelise iimveliso ezingafunekiyo.
Izinga loThutho lwe-Oxygen (I-otr), ilinganiswe nge $text{cc}/(\umbhalo{m}^2 cdot okubhaliweyo{usuku})$, yimetric esemgangathweni ye-OVP.
IpheleleI-Aluminium Barer Fielibonisa i-OTR eyi-zero, rhoqo ukuwa ngaphantsi kwemida yokubona yezixhobo zovavanyo olusemgangathweni (I-E.G., Izixhobo ze-MOCON).
Umngcipheko ophambili kwi-OVP kubukho bemibhobho okanye i-micro-cracks, enokuthi ingeniswe ngexesha lokuqengqeleka okanye iinkqubo zokuthambisa.
Itafile 1: Amazinga okuThutha kweOxygen (I-otr) yeZizinto zokuPakisha
| Uhlobo lwezinto eziphathekayo | Ukutyeba ($\um$m) | Iimeko zovavanyo | I-otr ($\umbhalo{cc}/(\umbhalo{m}^2 cdot okubhaliweyo{usuku})$) | Ukuhlelwa Kwezithintelo |
| I-PVC eqhelekileyo | 250 | $23^isangqaumbhalo{C}$, 0% Rh | 10 - 15 | Iphantsi |
| PVDC Coated PVC | 250 | $23^isangqaumbhalo{C}$, 0% Rh | 0.1 - 1.0 | Phakathi-Phezulu |
| Ifoyile yeAluminiyam ehlanganisiweyo | 25 (Al layer) | $23^isangqaumbhalo{C}$, 0% Rh | $< 0.005$ | Egqwesileyo |
| IFoil yeFomu ebandayo (Alu-Alu) | 45 (Al layer) | $23^isangqaumbhalo{C}$, 0% Rh | $< 0.001$ | Iphezulu |
4. UkuSebenza komqobo wokufuma (MVP)
Iqondo lokusasazeka kwe-vapor vapor (Wvtr), ilinganiswe nge $text{g}/(\umbhalo{m}^2 cdot okubhaliweyo{usuku})$, ihlala iyeyona parameter ibaluleke kakhulu kuzinzo lwechiza.
Umaleko we-aluminiyam uqinisekisa amaxabiso e-WVTR aphantsi kakhulu, ukwenzaI-Aluminium Barer Fieliyimfuneko kwi-hygroscopic APIs.
4.1 Inkqubo ye-Alu-Alu
Amachiza ajongana nokufuma kakhulu (I-E.G., Class I APIs), inkqubo ye-blister ye-Alu-Alu ibonelela ngokhuseleko oluphezulu.
Le nkqubo isebenzisa i-Aluminium ye-Aluminium foil ye-conding kunye neWebhu esisiseko (IFoil yeFomu ebandayo, Cff).
Inkqubo ye-CFF ifuna ulawulo oluchanekileyo ukuthintela uxinzelelo-lwe-micro-quatures kwi-muntickI-Aluminium Barer FielNgexesha lokuqulunqwa kwe-cavity.
Itafile 2: Ukusebenza kwe-WVTR kunye nokufaneleka kweefom zedosi eziqinileyo
| Iklasi ye-API | Ifuneka i-wvtr ($\umbhalo{g}/(\umbhalo{m}^2 cdot okubhaliweyo{usuku})$) | Isisombululo esiqhelekileyo sokupakisha | Isitshixo seSithintelo |
| Iklasi i (Inovelwano kakhulu) | $< 0.05$ | IFoil yeFomu ebandayo (Alu-Alu) | I-zero i-zero ye-al |
| Iklasi II (Ubuthathaka obuthathaka) | $0.05 - 0.5$ | I-PVDC / i-pvc blist ene-alupirum | I-PVDC COATHER kunye neTywina leAluminium |
| Iklasi i-III (Ubuncinci buthathaka) | $> 0.5$ | I-PVC eqhelekileyo / i-Aluminiyam Blister | Isitywina seAluminiyam yesiLiding |
5. UQinisekiso loMgangatho kunye noVavanyo lweMfezeko
Ukuqinisekisa ukusebenza ngokuzinzileyo kwemiqobo, ulawulo olungqongqo lwekhwalithi lunyanzelekile kuyo yonke inkqubo yokupakisha.
Uvavanyo lwePermeation (I-OTR kunye ne-WVTR) iqinisekisa iipropathi zangaphakathi zeflethiI-Aluminium Barer FielIzixhobo.
Emva kokupakishwa uvavanyo lubalulekile ukuqinisekisa ukuthembeka kwetywina lokugqibela le-hermetic, eyona ngongoma ixhaphakileyo yokusilela.
Iindlela ezifana nokungena kwedayi, ukubola kwevacuum, kunye nokufumanisa ukuvuza kombane ophezulu (HVLD) zisetyenziselwa ukuqinisekisa ingqibelelo yetywina.
Uhlalutyo lweMicroscopic kunye ne-electrochemical zisetyenziselwa ukukhangela kunye nokulinganisa imingxunya, ezibeka esichengeni kakhulu umsebenzi umqobo weI-Aluminium Barer Fiel.
Ukuqukumbela
Iifoyile ze-aluminiyam ezihlanganisiweyo zibonisa umgangatho wegolide wokufezekisa ukhuseleko lomqobo oluphezulu kwipakethe yamayeza. Uyilo lwabo lolwakhiwo luqinisekisa ukufikeleleka kwe-zero kuzo zombini ioksijini kunye nokufuma, ukukhusela uzinzo lwee-APIs ezinovakalelo. Intsebenzo iyonke iyonke ixhomekeke kumgangatho weI-Aluminium Barer Fiel Izixhobo kwaye ukuchaneka kwenkqubo yokugqibela yokutywina, inyanzelisa ukubambelela ngendlela eqhubekayo kwimigangatho yobuqhetseba.
