Unyaka we-1911 wawuyingqopha-mlando ebalulekile emlandweni wokupakishwa kokudla emhlabeni.Ngoba lo nyaka kwakuwunyaka wokuqala we-aluminium foil emkhakheni wokufakwa kokudla, futhi ngaleyo ndlela waqala uhambo lwayo olukhazimulayo emkhakheni wokupakisha ukudla.Njengephayona kuukufakwa kwe-aluminium foil, inkampani yaseSwiss chocolate ikhule ngaphezu kweminyaka eyi-100 futhi manje isibe uphawu oludumile (i-Toblerone).
I-aluminium foilngokuvamile ibhekisela ku-aluminium enobumsulwa obungaphezu kuka-99.5% kanye nogqinsi olungaphansi kwamamilimitha angu-0.2, kuyilapho i-aluminium foil esetshenziselwa izinto eziyinhlanganisela inogqinsi oluncane.Yiqiniso, amazwe ahlukene anezidingo ezihlukene zokuqina nokwakheka kwe-aluminium foil.Umbuzo uwukuthi, ingabe i-aluminium foil, ezacile njengamaphiko e-cicada, ingaba nekhono lomsebenzi obalulekile wokupakisha ukudla?Lokhu futhi kuqala ngomsebenzi wokupakisha ukudla kanye nezici ze-aluminium foil.Nakuba ukupakishwa kokudla ngokuvamile kungadleki, kuyingxenye ebalulekile yezimfanelo zemikhiqizo yokudla.Mayelana nomsebenzi wokupakisha ukudla, okuwumongo kakhulu umsebenzi wokuvikela ukudla.Ukudla kungena inqubo eyinkimbinkimbi kusukela ekukhiqizweni kuya ekusetshenzisweni, okungase kuthonywe izinto zangaphandle ezifana nebhayoloji, ikhemistri, kanye nefiziksi endaweni.Ukupakishwa kokudla kufanele kukwazi ukugcina ukuzinza kwekhwalithi yokudla nokumelana nemiphumela emibi ehlukahlukene endaweni ezungezile.Ngesikhathi esifanayo, ukupakishwa kokudla kufanele futhi kuhlangabezane nezidingo zobuhle, ukunethezeka, ukuvikelwa kwemvelo, kanye nokufinyeleleka.
Ake sibheke izici zei-aluminium foilfuthi.Okokuqala, ucwecwe lwe-aluminium lunamandla amakhulu emishini nomthelela othile kanye nokumelana nokubhoboza.Ngakho-ke, ngesikhathi sokugcina, ezokuthutha, nezinye izinqubo,aluminium foil ukudla okupakishweayilinyazwa kalula ngenxa yezinto ezinjengokuminyanisa, umthelela, ukudlidliza, umehluko wezinga lokushisa, njll. Okwesibili, ucwecwe lwe-aluminium lunomsebenzi ovimbelayo ophezulu, omelana kakhulu nokukhanya kwelanga, izinga lokushisa eliphezulu, umswakama, umoya-mpilo, ama-microorganisms, njll. Lezi zici ziyizi zonke izici ezikhuthaza ukonakala kokudla, futhi ukuvimba lezi zici kungandisa isikhathi seshelufu sokudla.Okwesithathu, i-aluminium foil kulula ukuyicubungula futhi inezindleko eziphansi, ezingahlangabezana nezidingo zokupakisha zokudla okuningi futhi inombala omhlophe oyisiliva omuhle kanye nokuthungwa okungaqondakali.Okwesine, i-aluminium yensimbi ngokwayo iyinsimbi engasindi, futhi ucwecwe lwe-aluminium oluncane kakhulu luhlangabezana nezidingo eziyisisekelo zokupakishwa okungasindi, okubaluleke kakhulu ekunciphiseni izindleko zokuhamba.Okwesihlanu, i-aluminium foil ayinabo ubuthi futhi ayinaphunga, kulula ukugaywa kabusha, futhi ihlangabezana nezidingo zokuvikelwa kwemvelo okuluhlaza kanye nentuthuko eqhubekayo.
Kodwa-ke, ekusebenzeni kokupakisha ukudla,i-aluminium foilngokuvamile ayivamisile ukusetshenziswa iyodwa, ngoba i-aluminium foil ngokwayo nayo inokushiyeka okuthile.Isibonelo, njengoba i-aluminium foil iqhubeka incipha, inani lama-pores lizokhula, okuzothinta ukusebenza kwesithiyo se-aluminium foil.Khonamanjalo, ucwecwe lwe-aluminium engasindi futhi oluthambile lunomkhawulo mayelana nokuqina nokuphikiswa kwe-shear, futhi ngokuvamile ayifanele ukupakishwa kwesakhiwo.Ngenhlanhla, i-aluminium foil inomsebenzi omuhle kakhulu wokucubungula wesibili.Imvamisa, izinto zokupakisha eziyinhlanganisela zingenziwa ngokuhlanganisa i-aluminium foil nezinye izinto zokupakisha ukuze kulungiswe ukushiyeka kwe-aluminium foil futhi kuthuthukiswe ukusebenza okuphelele kokupakisha kwezinto zokupakisha eziyinhlanganisela.
Ngokuvamile sibhekisela efilimini eyakhiwe ngezinto ezimbili noma ngaphezulu njengefilimu eyinhlanganisela, futhi isikhwama sokupakisha esenziwe ngefilimu eyinhlanganisela sibizwa ngokuthi isikhwama sefilimu esiyinhlanganisela.Ngokuvamile, ipulasitiki,i-aluminium foil, iphepha nezinye izinto zingenziwa zibe amafilimu ayinhlanganisela ngokusebenzisa isibopho noma ukuvala ukushisa ukuze kuhlangatshezwane nezidingo zokupakisha ezihlukahlukene zokudla okuhlukahlukene.Emaphaketheni esimanje, cishe zonke izinto ezihlanganisiwe ezidinga ukukhanya nokuvimbela okuphezulu zenziwei-aluminium foil njengesendlalelo sesithiyo, ngoba i-aluminium foil inesakhiwo sekristalu yensimbi eminyene kakhulu futhi inokusebenza okuhle kwesithiyo kunoma iyiphi igesi.
Emaphaketheni athambile okudla, kunento yokupakisha ebizwa ngokuthi “vacuum aluminized film”.Ingabe kuyafanai-aluminium foil eyinhlanganisela yezinto zokupakisha?Nakuba zombili ziqukethe ungqimba oluncane lwe-aluminium, aziyona into efanayo.Ifilimu ye-vacuum aluminium plating iyindlela yokuhwamuka nokufaka i-aluminium ehlanzekile kakhulu efilimini yepulasitiki endaweni yokungena, kuyilaphoi-aluminium foil eyinhlanganisela yezintoyakhiwe nge-aluminium foil nezinye izinto nge-bonding noma i-thermal bonding.
Ngokungafaniizinto ezihlanganisiwe ze-aluminium foil, ukumbozwa kwe-aluminium kufilimu egcwele i-aluminium ayinawo umthelela wokuvimbela we-aluminium foil, kodwa kunalokho ifilimu ye-substrate ngokwayo.Njengoba ungqimba lwe-aluminium luncane kakhulu kune-aluminium foil, izindleko zefilimu eyenziwe nge-aluminium ziphansi kunei-aluminium foil eyinhlanganisela yezinto, futhi imakethe yohlelo lokusebenza nayo ibanzi kakhulu, kodwa ngokuvamile ayisetshenziselwa ukupakisha i-Vacuum.
