Liyini Iqhubu Emaphethelweni Omlomo We-Easy Open Aluminium Can?

I-Aluminium can iyisitsha sokupakisha esivame kakhulu empilweni yethu yansuku zonke,

esetshenziswa kabanzi ekufakweni kweziphuzo kanye nokudla okuhlukahlukene. Abantu abaningi bangabona iqhubu elibonakalayo emaphethelweni omlomo wekani lapho kusetshenziswa ithini le-aluminium , kodwa bambalwa abazi isayensi ngemuva kanye nendima yalo mklamo. Ukubuza ukuthi yini engaphakathi kwalowo mbuthano ogobile ozungeze unqenqema lwekani le-aluminium, futhi uzovele uvele uthi, 'Ngiqinisekile ukuthi ayinalutho.' Kodwa akunjalo!

Ngo-1810, ukuze athuthukise ukulondolozwa kokudla, uPeter Durand waseNgilandi wasungula ithini lensimbi lokuqala emhlabeni. Nokho, kwaze kwaba ngemva kweminyaka engaphezu kwekhulu lapho kulula ukuvula i-aluminium can kwasungulwa khona ngempela. Ngo-1959, abantu baseMelika ngokusebenzisa emisha, ukusetshenziswa kungaba ukumboza izinto ezenziwe rippers, bese usetha ukudonsa indandatho kanye riveting, ngamagoli olunembile, ekhiqizwa ngempumelelo ephelele metal aluminium kalula evulekile can lid . Lokhu okusha kukhuthaze kakhulu ukuthuthuka kobuchwepheshe beziqukathi zensimbi. Ngawo-1970 kanye nawo-1980, ukukhiqizwa kwamathini e-aluminium kancane kancane kwasakazeka eJapane, eNingizimu Korea nakwezinye izifunda.

e-China, ekuqaleni kwawo-1980, i-Qingdao Brewery yethula amathini e-aluminium angu-2 anyatheliswe kahle avela eJapane okokuqala ngqa ukuze avumelane nezidingo zokupakishwa kokuthunyelwa kwemikhiqizo kwamanye amazwe, okwaphawula ukuqala kokusetshenziswa okubanzi kwamathini e-China. Amathini angahlukaniswa abe izigaba ezimbili eziyinhloko ngokuya ngezinto ezingavuthiwe: eyodwa yenziwe nge-tinplate, njenge-Lulu Almond Renlu kanye ne-JDB yokupakisha; Enye yenziwe nge-aluminium, njenge-Coca Cola ekheniwe nobhiya, iziphuzo ezine-carbonated nokunye.

Isakhiwo samathini ensimbi singaphinde sihlukaniswe sibe amathini aneziqephu ezimbili namathini aneziqephu ezintathu . Ithini elineziqephu ezintathu lakhiwe izingxenye ezintathu: umzimba wethini, ithini elingezansi kanye nekhava lekani. Umzimba wekani unamajoyinti, kanti umzimba wethini uxhunywe nekhava yekani bese kuthi ithini libe phansi ngonqenqema olugoqekayo. Amathini amabili akhiwe izingxenye ezimbili: i-can cover kanye ne-stampless seamless can body nephansi. Umzimba wethini kanye nesembozo sethini kwakheka kube yinto eyodwa ngokugingqika.

Ngamafuphi, uma i-aluminium isetshenziswa njengento esetshenziswayo, ngokuvamile yenziwa ithini elinezicucu ezimbili ; Uma kusetshenziswa i-tinplate, ikakhulukazi isesimweni samathini aneziqephu ezintathu . Umehluko omkhulu phakathi kwalokhu okubili inqubo yokukhiqiza yomzimba we-tank: amathini amabili awanawo ama-welds futhi enza i-jointless whole, esiza ukuvimbela ukuvuza.

Eqinisweni, umzimba we- i-aluminium can kwakhiwa ngokugxiviza amashidi e-aluminium. Ugqinsi lwaleli shidi le-aluminium lingaba ngamamilimitha angu-0.3. Phakathi nenqubo yokugxiviza, ishidi le-aluminium lifakwa ethuluzini elibizwa ngokuthi i-stretch die. I-cylindrical punch bese icindezela phansi eshidini ukusuka phezulu, iliguqule libe isilinda esifushane esimise okwe-ashtray. Le nqubo ibizwa ngokuthi ukugxiviza.

Nokho, ngemva kokunyathela okukodwa kuphela, isilinda esakhiwe ishidi le-aluminium sisabanzi futhi siwugqinsi, esingakafinyeleli ekumiseni kwekani lokugcina le-aluminium, ngakho-ke kudingeka ukugxivizwa okuningi. Ukugxiviza ngakunye kwenza ishidi le-aluminium libe lincane futhi libe lincane ngobubanzi, kuyilapho likhula ngobude. Ngemva kokunyathelisa okunjalo okuningana, ishidi lokuqala eliyindilinga eliyi-aluminium kancane kancane lakha uhlaka lwethini le-aluminium.

Kuleli qophelo, kunezinyathelo ezimbili kuphela ezisele zokwenza i-aluminium ingakwazi : enye iwukwenza ukucindezeleka phansi kwe-aluminium can, kanti enye iwukuba uyivale. Ukwakha ukudangala okuphansi kudinga kuphela ukusetshenziswa kwethuluzi elimise okwedome, elifana nenqubo yokugxiviza lapho ikani le-aluminium icindezelwa khona phezulu kwengxenye yesiyingi ukuze kwakheke umumo wokucindezeleka. Lo mklamo ohlehlisiwe ufana nebhuloho le-arch futhi uyakwazi ukumelana nokucindezeleka okukhulu. Zonke lezi zinqubo zihlangene zithatha ingxenye yesikhombisa kuphela yomzuzwana.

Ngemva kokusikwa okuphezulu kwethini le-aluminium, iphakheji yangaphandle ingafuthwa. Ngesikhathi esifanayo, ingaphakathi le-aluminium lingadinga futhi ukumbozwa ukuze kuvinjelwe iziphuzo ezine-asidi ukuthi zingasabelani ne-aluminium futhi zigweme ukudla ngokweqile kwe-aluminium okuthinta impilo yesimiso sezinzwa. Okulandelayo, intamo yekani idinga ukudonswa izacile ukuze kuvinjelwe imibimbi ethini le-aluminium elinezindonga ezincane. Okokugcina, isinyathelo esibucayi kakhulu ukuvala ithini le-aluminium, yingakho kuneqhubu elizungeze unqenqema lwe-aluminium can mouth.

Liyini iqhubu emaphethelweni ethini le-aluminium?

Ukuze i-soda ingavuzi, sivala phezulu kwethini le-aluminium. Kuleli qophelo, sekuyithuba lomlingiswa wethu namuhla - indandatho yesigubhu ukudlala indima. Le nqubo yokuvala amathini e-aluminium ibizwa nangokuthi ukubekwa uphawu kabili, ngakho-ke kuyini ukubekwa uphawu kabili?

Njengoba kuboniswe esithombeni esingezansi, okubomvu kumelele ishidi le-aluminium elisesivaloni sethini le-aluminium, kanti okuluhlaza okwesibhakabhaka kumelele ishidi le-aluminium emzimbeni wethini le-aluminium. Isivalo sethangi kanye nomugqa wethangi kuzofakwa ngokuqinile ngaphansi kwesenzo sokucindezela kwemishini, futhi le nqubo izokwakha ungqimba lokuqala lwerimu. Khona-ke, ngokufaka ukucindezela futhi, kwakheka ungqimba lwesibili lwamakhoyili, olutholakala ngaphakathi koqweqwe lokuqala lwezintambo. Ngale ndlela, kwakheka izingqimba ezimbili zezimpawu phakathi kwesivalo kanye nomzimba wethangi, okubukeka njengemiqulu yasentwasahlobo.

Kodwa-ke, ukubekwa uphawu okukabili ngokwako akukwazi ukuhlukanisa ngokuphelele ingaphakathi nangaphandle kwekani, kulolu ungqimba lokuvala kabili ngaphakathi kwegebe eligcwele i-liquid sealant. Isebenza njengeglue ekhethekile ebamba amashidi amabili e-aluminium ndawonye ngokuqinile futhi ivimbele isoda ukuthi ingavuzi. Ngaphezu kwalokho, ivimbela ukungcola ukuthi kungangeni ngaphakathi kwekani le-aluminium. Ukwakheka kwe-sealant ngokuvamile kuyingxube ye-latex, irabha noma inhlaka, futhi incibilike ku-solvent enamafutha. Ubani-ke owayengacabanga ukuthi uketshezi olunamafutha lungasongwa unqenqema lwethini le-aluminium?
