8021-O I-Aluminium foil: Ukwenza iikhowudi kwiiMfihlo ezingemva koMmandla oPhezulu kunye noKuchasana nokuGqwesa okugqwesileyo
Kwimeko entsonkothileyo yeshishini langoku, enye imathiriyeli ibalasele ngolungelelwaniso lwalo olulodwa lweempawu-zombini zinzima kwaye zihlala ixesha elide ngokuchasene nokonakaliswa kwendalo; inokumelana ne-encapsulation efunwayo yoshishino ngelixa ikhusela izinto ezibuthathaka ze-elektroniki. Yi le 8021-O yefoyile ye-aluminium, ifoyile ethambileyo ethambileyo esulungekiswe ngeenkqubo ezichanekileyo ngaphakathi kusapho oluthile lwealloyi. Eli nqaku liza kunika uhlalutyo olunzulu lokubunjwa kweekhemikhali, microstructure, iipropati eziphambili, iinkqubo zemveliso, kunye nezicelo ezahlukeneyo ze 8021-O yefoyile ye-aluminium, phendula imibuzo eqhelekileyo, kwaye unikeze ukuqonda okubanzi malunga nokuba kutheni le nto ikumgangatho ophezulu ilukhetho olukhethwayo kwiinkalo ezininzi..
I. IMbonakalo yeNzululwazi yeZixhobo: Uhlalutyo lokuBunjwa kunye neMicrostructure
Iimpawu zemacroscopic zayo naziphi na izinto zimiliselwe kwihlabathi layo elincinci. Iimpawu ezikhethekileyo ze 8021-O yefoyile ye-aluminiumKufuneka kuqala iqondwe ngokwakhiwa kweekhemikhali kunye nesiphumo sesakhiwo se-metallographic.
1.1 Uyilo oluchanekileyo lweMichiza
Ukwakheka kweekhemikhali eziqhelekileyo ze 8021 ingxubevange aluminiyamilawulwa ngokungqongqo kolu luhlu lulandelayo (ipesenti yobunzima), kunye nefilosofi yoyilo olungundoqo lulungelelwano olufanelekileyo phakathi kwamandla kunye nokumelana nomhlwa.
Itafile 1: Ukuqulunqwa kwemichiza eqhelekileyo ye 8021 Ingxubevange yeAluminiyam (Ubunzima %)
| Isiqalelo | Uluhlu lomxholo | Indima ephambili kunye nempembelelo |
|---|---|---|
| Intsimbi (Fe) | 1.0 – 1.5 | Undoqo Wokomeleza Element. Iifom zasasazwa iikhompawundi ze-AlFeSi intermetallic, ukudala umphumo wokomeleza ukusasazeka, nto leyo engundoqo ekwandiseni amandla. |
| Isilicon (Kwaye) | 0.05 – 0.20 | Idibanisa nentsimbi ukwenza izigaba ezizinzileyo zemvula, ukwandisa isiphumo sokomeleza ngelixa uphepha iimpembelelo ezinokubakho ezingalunganga ekuxhathiseni umhlwa kwi-silicon yasimahla. |
| Ubhedu (Cu) | ≤ 0.05 | Isiqalelo esilawulwa ngokungqongqo. Igcinwe iphantsi kakhulu ukuphelisa umngcipheko wokonakala kwegalvanic, kubalulekile ukuqinisekisa Ukunganyangeki kwe-Porrosion. |
| IManganese (Mnu) | ≤ 0.05 | Isiqalelo esilawulwa ngokungqongqo. Ikhusela ukubunjwa kwezigaba ezinobungozi, ukuqinisekisa i-microstructural homogeneity kunye nokumelana nokubola. |

| Aluminiyam (Al) | Ibhalansi | I-matrix ecocekileyo ephezulu, Ukubonelela ngombane kunye ne-thermal conductivity efanelekileyo kunye neempawu ezisisiseko zokulwa nokubola. |
Olu qulunqo-”phezulu Fe, phantsi Si, ubumdaka obuphantsi kakhulu (Cu, Mnu, Mg)”-sisiphumo sobunjineli obuchanekileyo ukufezekisa ukulingana okuhle phakathi kwamandla, ukubumbeka, kunye nokumelana nomhlwa.
1.2 I-Microstructure Emva kokufakwa kwe-Anealing (O umsindo)
“O” imele ukuhluthwa ngokupheleleyo. Emva kokubanda-iqengqeleke ukuya ubukhulu ekujoliswe kuyo, 8021 ifoyile yealuminiyamifumana unyango lobushushu olulawulwa ngokuchanekileyo kwiziko lokutshisa. Le nkqubo:
- Iphelisa Ukuqina Kwemisebenzi:Uxinzelelo lwangaphakathi kunye nokugqwethwa kwe-lattice ukusuka ekuqengqelekeni okubandayo kuyafunyanwa, ukwenza imathiriyeli ithambe kakhulu kwaye inyuse kakhulu ubude bayo.
- Uzinzisa ukuMvula:Iikhompawundi ze-Intermetallic ezenziwe ngentsimbi (I-E.G., Al₃fe) zisasazwe ngokufanayo njengamasuntswana amahle ngaphakathi kwe-aluminiyam matrix. La masuntswana aqinileyo, efana namatye ekhonkrithi, ngokufanelekileyo ukuthintela intshukumo dislocation. Oku kuvumela imathiriyeli ukuba igcine amandla asisiseko aphezulu xa kuthelekiswa nefoyile yealuminiyam ecocekileyo, nokuba uthanjisiwe (ilungele ukwenza). Oku kuqiniswa kokusasazwa yindlela encinci ye-microscopic emva kwe amandla aphezuluenokwenzeka ye 8021-O yefoyile ye-aluminium.
- I-Homogenizes iSakhiwo:Iziphumo kwiyunifomu, i-equiaxed recrystallized grain structure, ekhokelela kwiipropati ezihambelanayo nezizinzileyo.
II. Uhlalutyo olunzulu lweePropati eziPhambili: Afikelelwa Njani Amandla aphezulu kunye noKunyangwa kokuMhlwa
Ukuqonda ukwakheka kwayo kwangaphakathi kuvumela ukutolika okucacileyo kweempawu ezimbini zeempawu ze 8021-O yefoyile ye-aluminium.
2.1 Amandla aphezulu (Xa kuthelekiswa neFoil yeAluminiyam enyulu)
Apha, “amandla aphezulu” yingcamango ehambelanayo. Kwi “O” Ubushushu be-aluminium foil, sifuna “amandla amandla” kwisiseko se-ductility egqwesileyo.
Itafile 2: Uthelekiso lwePropati yoomatshini ye-8021-O vs. Iifoyile zeAluminiyam eziqhelekileyo ze-O-Temper
| Isalathisi sePropati | 8021-O I-Aluminium foil | 1235-O Ifoyile yeAluminiyam ecocekileyo | 3003-O I-Aluminium foil | Amagqabantshintshi |

| Tensile strength (MPa) | 100 – 140 | 70 – 100 | 110 – 150 | 8021-OAmandla aphezulu kakhulu kunefoyile yealuminiyam ecocekileyo, ukusondela ukuba 3003-O. |
| Unikeze Amandla (MPa) | 40 – 80 | 20 – 50 | 40 – 80 | Inika amandla esivuno aphakathi, ukwenza kube lula ukwenza iinkqubo. |
| Elongation (%) | ≥ 15 | ≥ 20 | ≥ 15 | Igcina i-ductility elungileyo, ilungele umzobo onzulu kunye nokwakheka okuntsokothileyo. |
| Inkqubo yokuQinisa okuPhambili | Ukomelezwa kokusasazwa (Izigaba ze-AlFe) | Ukomelezwa kweSicombululo esibuthathaka | Ukuqiniswa kwesisombululo esiqinileyo (Mnu) | 8021-Oifezekisa ulungelelwaniso lwamandla kunye nokubumba ngokomeleza ukusasazeka. |
- Intsingiselo Eluncedo:La mandla athetha ukuba ngexesha lokuqhubekeka okulandelayo (njengokunyathela kwiicasing zebhetri ze-lithium-ion okanye amaqokobhe e-capacitor), imelana ngcono ne-deformation engalinganiyo kunye nemibimbi, ukuphucula ukwenza uzinzo. Xa isetyenziswe njengoluhlu lwesithintelo kwizinto ezidibeneyo, inokumelana ne-lamination enkulu kunye noxinzelelo lwenkqubo elandelayo, ukunciphisa umngcipheko weepinki okanye ukuphuka ngenxa yokungonelanga kwamandla ngexesha lokuvelisa kunye nokusetyenziswa.
2.2 Ukuchasa okugqwesileyo kokuCorrosion

- Ucoceko lweMichiza:Ulawulo olungqongqo lwezinto ezifana nobhedu kunye ne-magnesium, ezithambekele ekubangeleni i-galvanic corrosion, inciphisa ngamandla amandla okuqhuba ukwenza iiseli ezincinci ezizonakalisayo.
- IziGaba zaseSekondari ezizinzileyo:Iikhompawundi ze-intermetallic ezenziwe ngentsimbi zi-inert ngokwekhemikhali kwaye azithandeki ukuba zibe ziindawo zokuqalisa ukubola okukhethekileyo kwiindawo ezininzi..
- Ifilimu exineneyo yeOxide:I-aluminiyam ngokwendalo yenza inxinana, i-alumina edlulayo (Al₂o₃) ifilimu. I-matrix ecocekileyo kunye nesakhiwo esifanayo 8021-O yefoyile ye-aluminiumqinisekisa ukuqhubeka kunye nokuxinana kwale filimu yeoxide, ukuthintela ngokufanelekileyo ukungena komswakama, ioksijini, kunye ne-electrolytes.
- Umboniso wokuSebenza:Kwiimvavanyo zokonakala kwesitshizi setyuwa, umhlwa ubushushu obumanzi, kunye nokuvezwa kwimithombo ye-asidi/alkali, 8021-O yefoyile ye-aluminiumisebenza ngcono kakhulu kunezinye iifoyile ezininzi zealluminiyam. Umzekelo, kwindawo yebhetri ye-lithium-ion ye-electrolyte (equlethe i-LiPF₆ kwii-esters eziphilayo), ukuxhathisa kwayo okugqwesileyo ku-corrosion kubalulekile ekuqinisekiseni ubomi bomjikelo wexesha elide kunye nokhuseleko lwebhetri.
