Imishini yokufaka itiye emakethe ingasetshenziswa ekupakisheni itiye ngokuzenzakalelayo, imikhiqizo yezempilo, ukudla nezinye izinto. Uma kuqhathaniswa nokupakishwa okwenziwe ngesandla kwangaphambilini, lokhu kupakisha okwenziwe ngomshini kunemisebenzi yokumelana nomswakama, ukumelana nephunga kanye nokugcina okusha. Thatha itiye elifakwe emasakeni njengesibonelo.

Sebenzisa umshini wokupakisha itiye ukuze upakishe. Okokuqala, izinto zingafakwa esikhwameni sangaphakathi, bese isikhwama sangaphakathi singafakwa esikhwameni sangaphandle ukuze kufezwe izinga eliphezulu lokuzenzakalela kwesikhwama sangaphakathi nesikhwama sangaphandle.

Uma usebenzisa umshini wokupakisha itiye, izinqubo zokwenza izikhwama, ukulinganisa, ukugcwalisa, ukuvala, ukusika nokubala zingaqedwa ngokuzenzakalelayo. Ngaphezu kwalokho, umshini wethu wokupakisha itiye ungashintsha ngokushesha imininingwane yezikhwama zokupakisha ngokwezidingo zenqubo yokupakisha. Ububanzi bungalungiswa kalula nangokushesha ngokulungisa isibambo, okungeke nje kuphela kuthuthukise ukusebenza kahle kokupakisha, kodwa futhi kuqinisekise umphumela wokupakisha wamaqabunga etiye.

1. Imelana nomswakama: Umswakama osetiyeni uyindlela yokushintsha kwamakhemikhali etiyeni, futhi okuqukethwe komswakama okuphansi kusiza ekulondolozweni kwekhwalithi yetiye. Umswakama osetiyeni akufanele udlule u-5%, futhi kungcono ukugcina u-3% isikhathi eside. Ngaphandle kwalokho, i-ascorbic acid esemaqabunga etiyeni ibola kalula, futhi umbala, iphunga kanye nokunambitheka kwamaqabunga etiye kuzoshintsha, ikakhulukazi lapho izinga lokushisa liphezulu, isivinini sokuwohloka sizosheshiswa.

Ngakho-ke, enkambisweni yokupakisha, ifilimu ehlanganisiwe enokusebenza okuhle okumelana nomswakama, njenge-aluminium foil noma i-aluminium foil vapor coating, ingakhethwa njengento eyisisekelo yokupakisha okumelana nomswakama. 2. Ukulwa nokugcwala: Okuqukethwe kwe-oxygen eningi ephaketheni kungaholela ekugcwaleni nasekuwohlokeni kwezinye izingxenye etiyeni. Isibonelo, i-ascorbic acid igcwala kalula ibe yi-deoxy kanye ne-ascorbic acid, futhi ihlanganiswe nama-amino acid ukukhiqiza ukusabela kombala okwenza kube kubi kakhulu ukunambitheka kwamaqabunga etiye.

Ngakho-ke, okuqukethwe komoya-mpilo ekupakisheni kwetiye kumele kulawulwe ngempumelelo ngaphansi kuka-1%. Ngokuphathelene nobuchwepheshe bokupakisha, ukupakisha okufuthwayo noma ukupakisha okufuthwayo kungasetshenziswa ukunciphisa ukuba khona komoya-mpilo. Ubuchwepheshe bokupakisha okufuthwayo (umshini wokupakisha oyimpuphu) ukufaka itiye esikhwameni sokupakisha sefilimu ethambile esinomoya oqinile, ukususa umoya esikhwameni ngesikhathi sokupakisha, ukukhiqiza izinga elithile le-vacuum, bese uvala indlela yokupakisha; ubuchwepheshe bokupakisha okufuthwayo buwukukhipha umoya Ngesikhathi esifanayo, kugcwele amagesi angasebenzi njenge-nitrogen ukuvikela umbala, iphunga kanye nokunambitheka kwamaqabunga etiye nokugcina ikhwalithi yokuqala yamaqabunga etiye.

3. Ukushisa okulwa nokushisa okuphezulu: izinga lokushisa liyisici esibalulekile esithinta ushintsho lwekhwalithi yetiye. Umehluko wokushisa ungu-10℃, futhi isivinini sokuphendula kwamakhemikhali siphindwe ka-3 ~ 5. Amaqabunga etiye azokhulisa ukubola kwezinto ezishisayo ekushiseni okuphezulu, okuholela ekunciphiseni okusheshayo kwezinto ezisebenzayo njenge-polyphenols, kanye noshintsho olusheshayo ekwehlukeni kwekhwalithi.

Ngokusho kokuqaliswa, izinga lokushisa lokugcina amaqabunga etiye liphansi kuno-5°C, futhi umphumela ungcono. Ku-10~15℃, umbala wamaqabunga etiye uyancipha kancane, futhi umphumela wombala ungagcinwa kahle. Uma izinga lokushisa lidlula u-25℃, umbala wamaqabunga etiye uzoshintsha ngokushesha.

Ngakho-ke, itiye lifanele ukugcinwa ekushiseni okuphansi. 4. Umthunzi: Ukukhanya kungakhuthaza ukushiswa kwe-chlorophyll, ama-lipid nezinye izinto emaqabungeni etiye, (umshini wokupakisha uketshezi) kungandisa izinto ezinuka njenge-valeraldehyde kanye ne-propionaldehyde emaqabungeni etiye, futhi kusheshise ukuguga kwamaqabungeni etiye. Ngakho-ke, lapho kufakwa amaqabungeni etiye, ukukhanya kumele kuvikelwe ukuze kuvinjelwe ukusabela kwe-photocatalytic kwezingxenye ezifana ne-chlorophyll kanye nama-lipid.

Ngaphezu kwalokho, imisebe ye-ultraviolet nayo iyisici esibalulekile esiholela ekuwohlokeni kwamaqabunga etiye. Amasu okupakisha angasetshenziswa ukubhekana nalezi zinkinga. 5. Ukumelana: Iphunga letiye lilahleka kalula, futhi lithinteka kalula yiphunga langaphandle, ikakhulukazi i-solvent esele yefilimu ehlanganisiwe kanye nokwelashwa ngogesi koku-ayina, kanye nephunga elibolile lokwelashwa kokuvala ukushisa lizothinta ukunambitheka kwetiye futhi lithinte ukunambitheka kwetiye.

Ngakho-ke, lapho upakisha amaqabunga etiye, kubalulekile ukugwema ukukhipha iphunga elivela ephaketheni bese umunca iphunga elivela ngaphandle. Izinto zokupakisha zetiye kumele zibe nezimpawu ezithile zokunciphisa igesi.
