Insimbi Ekupakishweni: Ifa Eliqinile

Kusukela ezinsukwini zokuqala zokulondoloza inyama yebutho likaNapoleon kuya ezitsheni eziyinkimbinkimbi, ezigaywa kabusha ezisetshenziswa namuhla, amathini ensimbi aye adlala indima ebalulekile ekulolongeni imboni yokudla yesimanje.

Ithini eliphansi lensimbi, eliwumgogodla wamaphethini ethu, linomlando ocebile owasukela eminyakeni engamakhulu amabili. Ekuqaleni kwethulwa ekuqaleni kwekhulu le-19, insimbi yakhethwa ukupakishwa ngenxa yamandla ayo nokuqina.

Lesi sinqumo siphawule ukusungulwa okusha okubalulekile ekugcineni ukudla, okwenza ukudla kugcinwe futhi kuthuthwe amabanga amade ngaphandle kokonakala.

Umsuka wensimbi emaphaketheni uhambisana nendaba kaNicolas Appert, umsunguli ongumFulentshi owathola ukuthi ukudla kwakungalondolozwa ngokukuvalela emabhodleleni futhi kufudumale—indlela yokuqala yokufaka amathini.

Naphezu kokusetshenziswa kokuqala kwengilazi, ukushintshela ensimbi kwakubalulekile. Ngo-1810, umthengisi oyiNgisi u-Peter Durand wagunyaza ukusetshenziswa kwezigqoko zensimbi ezinamekwe ngothayela, okwenza izinguquko embonini.

Lawa mathini akudala ayenziwe ngamashidi ensimbi acwiliswe othanini obuncibilikisiwe, avalwa ngokuthengiswa ngemva kokugcwaliswa. Le ndlela, nakuba idinga abasebenzi abaningi, yaba impumelelo ekulondolozweni kokudla, ibeka inkundla yezinhlelo zokusabalalisa ukudla emhlabeni wonke esithembele kuzo namuhla.

Ukufakwa kokudla: ukuqamba okusha okuhle

Umthelela womsebenzi ka-Nicolas Appert kanye nokuthuthukiswa okwalandela kwe-tin canister akunakugcizelelwa. Ukudla okusemathinini kwaqala njengesidingo sezempi kodwa ngokushesha kwaba ukudla okuyisisekelo kwabantu, okuvumela ukugcinwa okuphephile, isikhathi eside kokudla okuhlukahlukene kusukela enyameni nasemifino kuya ezithelweni nasebisini.

Inqubo yokufaka amathini yaqala eBrithani lapho uBryan Donkin noJohn Hall bethenga i-patent yokufaka futhi basungula imboni yokuqala ngo-1813.

Ukugunyazwa kobukhosi kweNkosi uGeorge III kwakhulisa ukuthandwa kokudla okusemathinini, futhi maphakathi nekhulu le-19, ukukheniwa kwase kusakazekele eMelika nangale kwayo.

Ubuchwepheshe be-Canning bavela ngokushesha; ngasekupheleni kwawo-1800, imishini yayikwazi ukukhiqiza izinkulungwane zamathini ngehora, intuthuko enkulu phezu kwezindlela ezenziwe ngesandla. Lesi sikalo somkhiqizo sashintsha imboni yokudla, senza ukudla okulondoloziwe kufinyeleleke futhi kufinyeleleke kubantu abaningi.

Iphinde yagqugquzela ukuqanjwa kabusha kwe-can design, okuhlanganisa ukwethulwa kwamathini aneziqephu ezimbili nantathu, okuthuthukise ukusebenza kahle nokuphepha kwamathini.

Izinhlelo zesimanje ze-can kanye nokusimama

Amathini ensimbi anamuhla ayisimangaliso sobunjiniyela, aklanyelwe ukuqina nokuqina. Ukwenza amathini esimanje kuhilela amasu ayinkimbinkimbi afana ne-electrochemical coating kanye ne-electric seam welding, eye yathuthukisa kakhulu ikhwalithi nokuphepha kwempahla ekheniwe.

Ukwengeza, amathini esimanje angase abe nama-lacquers noma ama-polymeric linings ukuvimbela ukugqwala nokuvikela ubuqotho bokuqukethwe kwawo.

Amathini ensimbi anikeza izinzuzo eziningana zemvelo. Ziyakwazi ukuphinda zisetshenziswe ngo-100%, futhi amazinga okugaywa kabusha e-Europe adlula ama-72%. Inqubo yokugaywa kabusha iyasebenza, igcina ikhwalithi yensimbi futhi inciphisa kakhulu indawo ezungezile ehlobene nokukhiqizwa kwekani.

Ngaphezu kwalokho, ukuvalwa kwe-hermetic kwamathini kuvikela ukudla ekukhanyeni, kumoya-mpilo, nasemswakameni, kunwebe isikhathi seshalofu ngaphandle kwesidingo sezinto ezilondolozayo futhi kunciphisa ukumosheka kokudla.

Ikusasa lensimbi yokupakisha

Naphezu kokuncintisana kwezinto ezintsha ezifana namapulasitiki ne-aluminium, insimbi isalokhu iyisisekelo semboni yokupakisha ngenxa yokuphinda isetshenziswe kanye nokuvikela okuqinile ekunikezayo.

Kodwa-ke, imboni kufanele iqhubeke nokusungula izinto ezintsha ukuze ihlangabezane nezidingo zabathengi ezishintshayo kanye namazinga emvelo. Ukwanda kokuthengwa kwezinto eziluhlaza kanye nokuphushela ezixazululweni ezisimeme zokupakisha kubangela izinselelo kodwa namathuba embonini yensimbi.

Njengoba sibheke esikhathini esizayo, ikhono lensimbi lokuzivumelanisa nezimo lizobaluleka. Ukuqamba okusha kungaklama okwehlisa ukusetshenziswa kwezinto ngenkathi kugcinwa ukusebenza, okufana neziphetho ezivuleka kalula kanye nokusetshenziswa kabusha okuthuthukisiwe, kuzosiza insimbi igcine ukuhambisana kwayo emakethe encintisanayo.

Ngaphezu kwalokho, ukuqonda nokusabela kokuncanyelwayo kwabathengi ngezinketho zokudla ezingacutshungulwa kancane nezintsha kuzobaluleka.

Amathini ensimbi abeyingxenye ebalulekile yochungechunge lwethu lokuhlinzekwa kokudla iminyaka engaphezu kwengu-200, ebonisa ukuqina okumangalisayo nokuzivumelanisa nezimo.

Njengoba imboni yokupakisha ithuthuka, ukuqina kanye nokusimama kwensimbi kuzoqhubeka nokuba amandla ayo amakhulu, kuqinisekiswe ukuthi ihlala iyingxenye ebalulekile yokuphila kwethu kwansuku zonke.
