Kungakhathaliseki ukuthi upakisha ubhiya noma udlulela ngale kukabhiya kwezinye iziphuzo, kuyakhokhela ukucabangela ngokucophelela amandla amafomethi e-can ahlukahlukene futhi angase afaneleke kakhulu imikhiqizo yakho.

Ukushintsha Kwesidingo Ngamathini

Eminyakeni yamuva nje, amathini e-aluminium akhule ngokuthandwa. Okwake kwabhekwa njengomkhumbi oyinhloko wemikhiqizo eshibhile enkulu manje sekuyifomethi yokupakisha ekhethwayo yemikhiqizo yezandla zeprimiyamu cishe kuzo zonke izigaba zesiphuzo. Lokhu kubangelwa kakhulu izinzuzo ezinikezwa amathini: ikhwalithi ephezulu, izindleko eziphansi, ukuguquguquka kokusebenza, kanye nokuphinda kusetshenziswe okungapheli. Kuhlanganiswe nokushintsha kwesidingo sabathengi kanye nokwenyuka kwamaphakheji azohamba, akumangazi ukuthi ngaphezu kwezingxenye ezimbili kwezintathu zazo zonke iziphuzo ezintsha zipakishwe emathini e-aluminium.

Kodwa-ke, uma kuziwa ekuhloleni amathini ezinhlobo eziningi zeziphuzo, ingabe zonke izinto ziyalingana?

Okucatshangelwayo Okubalulekile ku-Can Packaging

Ngokusho kwe-Association for Packaging and Processing Technologies, amaphesenti angu-35 abathengi aphendukela eziphuzweni ukuze ahlanganise izithako ezisebenzayo ekudleni kwabo. Ngaphezu kwalokho, abathengi babeka inani elikhulayo kumafomethi alula afana namaphakheji alungele ukuphuzwa. Lokhu kuholele ekutheni abakhiqizi beziphuzo bandise iphothifoliyo yemikhiqizo yabo, bethule izitayela ezintsha nezithako eziningi kunangaphambili. Empeleni, izinketho zokupakisha nazo ziyathuthuka.

Uma ungena noma unweba ukupakishwa kwe-can, kubalulekile ukuhlola izici eziyisisekelo zomkhumbi ngokwawo ngokuhlobene nokuqukethwe kanye nezidingo zomkhiqizo zomkhiqizo ngamunye onikezwayo. Lokhu kuhlanganisa ukucatshangelwa ngokucophelela kokutholakala kwekani, isitayela sokuhlobisa, futhi—okubaluleke kakhulu—ukuhambisana komkhiqizo nephakheji.

Nakuba amathini amafomethi amancane kanye/noma amancane ehlinzeka ngokuhlukanisa emashalofini okuthengisa, kubalulekile ukuqaphela ukuthi ukukhiqizwa kwawo kuhlanganiswe futhi kulinganiselwe kakhulu uma kuqhathaniswa “nosayizi we-core can” atholakala kalula (12oz/355ml standard, 16oz/473ml standard, 12oz/355ml sleek kanye no-10.2oz/310ml okuchachambile). Ngokuhlanganyela, usayizi weqoqo kanye nemvamisa yokupakishwa kubalulekile ekubikezelweni njengoba kuhlobana ngokuqondile namavolumu ama-oda amancane kanye nokugeleza kwemali noma izidingo zokugcinwa, kanye nokufinyeleleka ezinkethweni ezihlukahlukene zokuhlobisa amathini.

Amathini e-aluminium angenalutho, aziwa nangokuthi amathini ama-brite, anikeza ukuguquguquka okukhulu kokukhiqiza. Uma kubhangqwe namalebula azwela ukucindezela , abakhiqizi bangaqondanisa ukukhiqiza namavolumu okuthengisa cishe nganoma yiliphi inani le-oda endaweni yenani eliphansi uma kuqhathaniswa.

Njengoba usayizi weqoqo kanye/noma izidingo zokuhlobisa zanda, amathini omkhono oshwabene aba inketho esebenzayo. Amanani e-oda ahlala ephansi—ngokuvamile ephalethi eliyisigamu—kodwa amandla okuhlobisa akhula ngamalebula angu-360-degree, anombala ogcwele ezinkethweni eziningi zokuvanisha.

Amathini aphrintelwe ngedijithali ayinketho yesithathu yokuhlobisa, enikeza amandla okuphrinta okukhava okugcwele ngamanani aphansi aphansi, kodwa anephuzu lentengo eliphezulu kunamakani emikhono emikhono. Emavolumu ama-oda amakhulu, iloli elilodwa noma ngaphezulu, amathini aphrintiwe e-offset ayinketho yokugcina futhi eyonga kakhulu ye-can ehlotshisiwe.

Ukuqonda Ukuhambisana Komkhiqizo Nephakheji
Nakuba ukufinyeleleka nobuhle kubalulekile ekuthuthukisweni komkhiqizo, ukucatshangelwa okubaluleke kakhulu nokuvame ukunganakwa ukuhambisana komkhiqizo nephakheji. Lokhu kunqunywa izibalo zekhemistri kanye nemingcele ehlanganisa ukwakhiwa kweresiphi yesiphuzo ngokuhambisana nezicaciso zokukhiqiza zekani, ikakhulukazi i-liner yangaphakathi.

Ngenxa yokuthi izindonga zekani zincane kakhulu, ukuthintana phakathi kwayo nezinto ezingavuthiwe ze-aluminium kuzoholela ekugqwaleni kwensimbi namakani avuzayo. Ukuze uvimbele ukuthintana okuqondile futhi ugweme lokhu konakala, amathini esiphuzo ngokwesiko afafazwa ngesimbozo sangaphakathi ngesikhathi sokukhiqiza ngesivinini esingafika kumakani angu-400 ngomzuzu.

Emikhiqizweni eminingi yesiphuzo, ukuhambisana komkhiqizo nephakheji akunandaba kusetshenziswa le nqubo yohlelo. Kodwa-ke, ikhemistri ehambisanayo akufanele ishaywe indiva njengoba ukwakhiwa kolayini, ukuvumelana kohlelo nokujiya kungahluka ngomkhiqizi kanye/noma uhlobo lwesiphuzo. Isibonelo, kunqunyelwe ukupakishwa kwe-can ukuthi uma i-pH iphezulu futhi ukugxila kwe-Cl kuphansi, ukugqwala mancane amathuba okuthi kwenzeke. Ngokuphambene, iziphuzo ezinokuqukethwe okuphezulu kwama-asidi e-organic (i-acetic acid, i-lactic acid, njll) noma usawoti omningi ungase uthande ukugqwala ngokushesha.

Emikhiqizweni kabhiya, ukugqwala mancane amathuba okuthi kwenzeke ngenxa yokuthi i-oxygen encibilikisiwe idliwa ngokushesha, nokho, kwezinye izinhlobo zesiphuzo ezifana newayini, ukugqwala kungenzeka kalula uma i-pH iphansi futhi ukugxila kwe-SO2 yamahhala kuphezulu.

Ukwehluleka ukuhlola kahle ukuhambisana komkhiqizo nephakheji nomkhiqizo ngamunye kungase kubangele ukukhathazeka kwekhwalithi okulimazayo okubangelwa ukugqwala okudla ithini kanye nolayini kusuka ngaphakathi nangaphandle. Lokhu kukhathazeka kuhlanganisa kuphela isitoreji njengoba umkhiqizo ovuzayo uconsa phansi ukuze uthinte izindonga ezingavikelekile, zangaphandle zamathini e-aluminium ngezansi okuholela ekuwohlokeni kokugqwala kanye nokwanda kokuhluleka kwe-can-body.

Ngakho-ke, umkhiqizi wesiphuzo unwebeka kanjani ekukhiqizeni utshwala “ngale kobhiya” futhi aphishekele ngempumelelo ukupakishwa kwazo zonke izinhlobo zesiphuzo—okuhlanganisa ama-seltzers, ama-RTD cocktail, iwayini, nokunye? Ngenhlanhla, izinsiza zasekhaya ziyahlukahluka ukuze zikwazi ukuthwala kangcono uhlu olubanzi lomkhiqizo opakishiwe.
