Ibhegi yokupheka ephezulu yobushushu yinto emangalisayo.Sisenokungayiqapheli le phakheji xa sidla ngokutya.Enyanisweni, i-high-temperature bag yokupheka ayiyona isikhwama esiqhelekileyo sokupakisha.Iqulethe isisombululo sokufudumala kwaye luhlobo oludibeneyo.Isikhwama sokupakisha iimpawu, kunokuthiwa ukuba isikhwama sokushisa esiphezulu sidibanisa iimpawu zesitya kunye nesikhwama sokupheka.Ukutya kunokugcinwa kwisikhwama, emva kokutshatyalaliswa kunye nokufudumeza kwiqondo lokushisa eliphezulu (ngokuqhelekileyo i-120 ~ 135 ℃), inokutyiwa emva kokuyisusa.Emva kweminyaka engaphezu kweshumi yokusetyenziswa, kuye kwangqinwa ukuba yeyona nto ilungileyo yokupakisha isikhongozeli.Ilungele ukupakishwa kwenyama kunye neemveliso zesoya, ezilungeleyo, ezicocekileyo nezisebenzayo, kwaye zinokugcina incasa yokuqala yokutya, ethandwa ngabathengi.
Kuyaqondwa ukuba upakisho lwakuqala olunokugcina ukutya kwenyama kwiqondo lobushushu begumbi kukutya okunkonkxiweyo, okuyintsimbi eyenziwe nge-tinplate, kwaye kamva isebenzisa iibhotile zeglasi njengepakethe yangaphandle.Zomibini iibhotile ze-tinplate kunye neglasi zinokumelana nokushisa okuphezulu kokupheka kunye neempawu eziphezulu zokuthintela, ngoko ke ubomi beshelufu yokutya okusemathinini bunokufikelela ngaphezu kweminyaka emi-2.Nangona kunjalo, ngenxa yokuba iitoti ze-tinplate kunye neebhotile zeglasi zizikhongozeli zokupakisha eziqinileyo ezinomthamo omkhulu kunye nobunzima obunzima, i-tinplate inokumelana nekhemikhali engalunganga, ngakumbi xa ilayishwe kukutya okuneasidi, iiyoni zetsimbi ziyagaleka ngokulula, ezichaphazela incasa yokutya.Ngeminyaka yee-1960, iUnited States yavelisa ifilimu ehlanganisiweyo ye-aluminiyam-yeplastiki ukuze isombulule ukupakishwa kokutya kwe-aerospace.Isetyenziselwa ukupakisha ukutya kwenyama, kwaye inokugcinwa kwindawo yokushisa ngokushisa okuphezulu kunye noxinzelelo oluphezulu lokuvala inzala, kunye neshelufu yobomi obungaphezu konyaka omnye.Indima yefilimu edibeneyo ye-aluminium-iplastiki ifana ne-can, ethambileyo kwaye ilula, ngoko ibizwa ngokuba "i-soft can".
Ngokumalunga nokupakishwa kokutya, iibhegi zokubuyisela ubushushu obuphezulu zinezinto ezininzi ezizodwaiingeneloxa kuthelekiswa nezikhongozeli zentsimbi kunye neengxowa zokupakisha ezikhenkcezisiweyo:
①Gcina umbala,ivumba, incasa kunye nokumila kokutya.Ingxowa yokubuyisela iyancipha, kwaye inokuhlangabezana neemfuno zokuvala inzala ngexesha elifutshane, kwaye igcine umbala wokuqala, ivumba, incasa kunye nokumila kokutya kangangoko kunokwenzeka.
kulula ukuyisebenzisa.Ingxowa ye-retort inokuvulwa ngokulula nangokukhuselekileyo.Xa usitya, beka ukutya kunye nengxowa emanzini abilayo kwaye ushushuze imizuzu emi-5 ukuze uvule kwaye utye, ngaphandle kokufudumeza.
②Ugcino olufanelekileyo kunye nokuthutha.Ingxowa yokupheka ilula ngobunzima, inokupakishwa kwaye igcinwe, kwaye ithatha indawo encinci.Emva kokupakisha ukutya, indawo ehlala kuyo incinci kuneyentsimbi, enokuthi isebenzise ngokupheleleyo indawo yokugcina kunye nokuthutha kunye nokugcina iindleko zokugcina kunye nokuthutha.
gcina amandla.Ngenxa yokunciphisa isikhwama sokupheka, isikhwama sinokufikelela kwiqondo lokushisa elibulalayo lebhaktheriya ngokukhawuleza xa lishushu, kwaye ukusetyenziswa kwamandla ngama-30-40% ngaphantsi kwe-iron can.
③lula ukuthengisa.Iingxowa ze-retort zinokupakishwa okanye zidibaniswe nokutya okuhlukeneyo ngokweemfuno zemarike, kwaye abathengi banokukhetha ngokuthanda.Ukongeza, ngenxa yembonakalo entle, umthamo wokuthengisa nawo unyuswe kakhulu.
④ixesha elide lokugcina.Ukutya okupakishwe kwiingxowa zokubuyisela okungadingi kukhenkciswa okanye ukukhenkceza, kubomi beshelufu obuzinzileyo obunokuthelekiswa neetoti zentsimbi, kulula ukuthengisa, kwaye kulula ukuzisebenzisa ekhaya.
⑤indleko ephantsi yokwenziwa.Iindleko zefilimu edibeneyo yokwenza isikhwama se-retort singaphantsi kuneso sicwecwe sesinyithi, kwaye inkqubo yokuvelisa kunye nezixhobo ezifunekayo zilula kakhulu, ngoko ke ixabiso lesikhwama sokubuyisela liphantsi.
Isakhiwo semveliso yeengxowa zokupheka eziphezulu
Ngokuqhelekileyo yahlulahlulwe yaba ngamacandelo amathathu: ifilimu enemigangatho emibini, ifilimu enemigangatho emithathu kunye nesakhiwo sefilimu enemigangatho emine.
Ifilimu enemigangatho emibini ngokubanzi yiBOPA/CPP,PET/CPP;
Ulwakhiwo lwefilimu enemigangatho emithathu yiPET/AL/CPP,BOPA/AL/CPP;
Isakhiwo sefilimu enemigangatho emine yi-PET / BOPA / AL / CPP, PET / AL / BOPA / CPP.
Ukuhlolwa kokumelana nokushisa okuphezulu
Emva kokuba isikhwama senziwe, faka umthamo ofanayo womxholo kwisikhwama kwaye utywine kakuhle (Qaphela: umxholo ufana nomxholo ochazwe ngumthengi, kwaye uzame ukukhupha umoya engxoweni xa utywinwa, ukuze ungabikho. ichaphazela isiphumo sovavanyo ngenxa yokwanda komoya ngexesha lokupheka), Yibeke kwi-ts-25c yoxinzelelo lwangasemva embizeni yokupheka ubushushu obuphezulu, kwaye usete iimeko ezifunwa ngumthengi (ubushushu bokupheka, ixesha, uxinzelelo) ukuvavanya ukumelana nobushushu obuphezulu;inkqubo yokwenziwa kwengxowa yokupheka yobushushu obuphezulu okwangoku yeyona bhegi yokupheka ibalaseleyo emhlabeni.Uninzi lwazo lwenziwa ngendlela eyomileyo yokudibanisa, kwaye ezimbalwa zisenokwenziwa ngendlela yokudibanisa i-solvent-free okanye indlela yokudibanisa i-co-extrusion.
Ukuhlolwa kokubonakala emva kokupheka: isikhwama sesikhwama sithe tyaba, singenamibimbi, i-blistering, i-deformation, kwaye akukho kuhlukana okanye ukuvuza.
