Ingxowa yokupheka enobushushu obuphezulu yinto entle kakhulu. Sisenokungayiboni le phakheji xa sidla ngokutya. Enyanisweni, ingxowa yokupheka enobushushu obuphezulu ayisiyongxowa yokupakisha eqhelekileyo. Iqulethe isisombululo sokufudumeza kwaye luhlobo oludibeneyo. Ingxowa yokupakisha ephawulekayo, kunokuthiwa ingxowa yokupheka enobushushu obuphezulu idibanisa iimpawu zesixhobo kunye nengxowa yokupheka. Ukutya kunokuhlala kuhleli ebhegini, emva kokuba kucocwe kwaye kufudunyezwe kubushushu obuphezulu (ngesiqhelo i-120 ~ 135℃), kunokutyiwa emva kokuyisusa. Emva kweminyaka engaphezu kweshumi yokusetyenziswa, kuye kwabonakala ukuba sisikhongozeli sokupakisha esifanelekileyo sokuthengisa. Ifanelekile ekupakisheni inyama kunye neemveliso zesoya, elula, ecocekileyo nesebenzayo, kwaye inokugcina incasa yokuqala yokutya, ethandwa ngabathengi.
Kuyaqondakala ukuba ukupakisha kokuqala okunokugcina ukutya kwenyama kubushushu begumbi kukutya okusemathinini, okuyitini yentsimbi eyenziwe ngetini, kwaye kamva kusebenzisa iibhotile zeglasi njengepakethe yangaphandle. Zombini iibhotile zetini kunye neglasi zinokumelana nokupheka okushushu kakhulu kunye neempawu zokuthintela okuphezulu, ngoko ke ubomi beshelufu bokutya okusemathinini bunokufikelela kwiminyaka engaphezu kwemi-2. Nangona kunjalo, ngenxa yokuba iitini zetini kunye neebhotile zeglasi zizikhongozeli zokupakisha eziqinileyo ezinomthamo omkhulu kunye nobunzima obunzima, itini ayinakho ukumelana nokugqwala kweekhemikhali, ingakumbi xa igcwele ukutya okune-asidi, ii-ion zesinyithi ziyakhawuleza ukugaleleka, nto leyo echaphazela incasa yokutya. Ngeminyaka yoo-1960, i-United States yasungula ifilimu ye-aluminium-plastic composite ukuze isombulule ukupakisha kokutya kweenqwelo-moya. Isetyenziselwa ukupakisha ukutya kwenyama, kwaye ingagcinwa kubushushu begumbi ngobushushu obuphezulu kunye nokucoca uxinzelelo oluphezulu, kunye nobomi beshelufu obungaphezu konyaka omnye. Indima yefilimu ye-aluminium-plastic composite ifana neyetini, ethambileyo kwaye ilula, ngoko ke ibizwa ngokuba yi-"tin ethambileyo".
Ngokuphathelele ukupakisha ukutya, iingxowa zokuziphendulela ezinobushushu obuphezulu zinezinto ezininzi ezikhethekileyoiingeneloxa kuthelekiswa nezikhongozeli zesinyithi zokugalela ukutya kunye neengxowa zokupakisha ukutya ezikhenkcezisiweyo:
①Gcina umbala,ivumba, incasa kunye nesimo sokutya.Ingxowa yokuziphendulela incinci, kwaye ingahlangabezana neemfuno zokubulala iintsholongwane ngexesha elifutshane, kwaye igcine umbala wokuqala, ivumba, incasa kunye nesimo sokutya kangangoko kunokwenzeka.
kulula ukuyisebenzisa.Isikhwama sokuphendula singavulwa ngokulula nangokukhuselekileyo. Xa usitya, faka ukutya kunye nebhegi emanzini abilayo uze ukufudumeze imizuzu emi-5 ukuze kuvulwe kwaye kutyiwe, nokuba akufudunyezwanga.
②Indawo yokugcina izinto kunye nokuthuthwa kwazo kulula.Ingxowa yokupheka ilula ngobunzima, ingafakwa ize igcinwe, kwaye ithatha indawo encinci. Emva kokupakisha ukutya, indawo esetyenziswayo incinci kuneyengqayi yesinyithi, enokusebenzisa ngokupheleleyo indawo yokugcina nokuthutha kwaye yonge iindleko zokugcina nokuthutha.
gcina amandla.Ngenxa yobuncinci bebhegi yokupheka, ibhegi inokufikelela kubushushu obubulalayo beebhaktheriya ngokukhawuleza xa ishushu, kwaye ukusetyenziswa kwamandla kungaphantsi ngama-30-40% kunokwengqayi yesinyithi.
Kulula ukuyithengisa.Iingxowa zokuzilungisa zingapakishwa okanye zidityaniswe nokutya okwahlukileyo ngokweemfuno zemarike, kwaye abathengi banokukhetha ngokuthanda kwabo. Ukongeza, ngenxa yembonakalo entle, umthamo wentengiso nawo unyuswe kakhulu.
④ixesha elide lokugcina.Ukutya okupakishwe kwiingxowa ezingafuni friji okanye ukukhenkcezwa, okuhlala ixesha elide xa kuthelekiswa neetini zesinyithi, kulula ukuthengisa, kwaye kulula ukukusebenzisa ekhaya.
⑤ixabiso eliphantsi lokuvelisa.Ixabiso lefilimu edityanisiweyo yokwenza ingxowa yokujika liphantsi kunelepleyiti yesinyithi, kwaye inkqubo yokuvelisa kunye nezixhobo ezifunekayo zilula kakhulu, ngoko ke ixabiso lengxowa yokujika liphantsi.
Ulwakhiwo lwemveliso yeengxowa zokupheka ezishushu kakhulu
Ngokubanzi yahlulwe yangamacandelo amathathu: ifilimu enamaleko amabini, ifilimu enamaleko amathathu kunye nesakhiwo sefilimu enamaleko amane.
Ifilimu enamaleko amabini ngokubanzi yiBOPA/CPP, PET/CPP；
Ulwakhiwo lwefilimu oluneeleya ezintathu yiPET/AL/CPP、BOPA/AL/CPP；
Ulwakhiwo lwefilimu oluneeleya ezine yiPET/BOPA/AL/CPP，PET/AL/BOPA/CPP。
Ukuhlolwa kokumelana nokupheka kubushushu obuphezulu
Emva kokuba ibhegi yenziwe, faka umthamo ofanayo womxholo ebhegini uze uyivale kakuhle (Qaphela: umxholo ufana nomxholo ochazwe ngumthengi, kwaye uzame ukukhupha umoya ebhegini xa uyivala, ukuze ungachaphazeli isiphumo sovavanyo ngenxa yokwanda komoya ngexesha lokupheka). Yifake kwimbiza yokupheka enobushushu obuphezulu be-ts-25c, kwaye ubeke iimeko ezifunekayo kumthengi (ubushushu bokupheka, ixesha, uxinzelelo) ukuvavanya ukumelana nokupheka kobushushu obuphezulu; inkqubo yokuvelisa ibhegi yokupheka enobushushu obuphezulu okwangoku yeyona bhegi yokupheka ilungileyo ehlabathini. Uninzi lwazo lwenziwa ngendlela yokudibanisa eyomileyo, kwaye ezimbalwa zinokwenziwa ngendlela yokudibanisa engenasombululo okanye indlela yokudibanisa edibeneyo.
Ukuhlolwa kwenkangeleko emva kokupheka: umphezulu wengxowa uthe tyaba, awunamibimbi, unamadyungudyungu, uqhekeke, kwaye akukho kwahlukana okanye ukuvuza.
