Kunezinhlobo eziningi zezikhwama zokupakisha ukudla ezisetshenziselwa ukupakisha ukudla, futhi zinokusebenza kwazo okuhlukile nezici.Namuhla sizoxoxa ngolwazi oluvame ukusetshenziswa lwezikhwama zokupakisha ukudla ukuze uthole inkomba yakho.Ngakho siyini isikhwama sokupakisha ukudla?Izikhwama zokufaka ukudla ngokuvamile zibhekisela kumapulasitiki afana neshidi anogqinsi olungaphansi kuka-0.25 mm njengamafilimu, futhi ukupakishwa okuguquguqukayo okwenziwe ngamafilimu epulasitiki asetshenziswa kakhulu embonini yokudla.Kunezinhlobo ezahlukene zezikhwama zokupakisha ukudla.Ziyabonakala, ziguquguquka, zikwazi ukumelana namanzi kahle, ukumelana nomswakama kanye nezindawo zokuvimbela igesi, amandla amahle emishini, izakhiwo zamakhemikhali ezinzile, ukumelana nowoyela, kulula ukuphrinta kahle, futhi zingavalwa ngokushisa ezikhwameni.Ngaphezu kwalokho, amaphakheji okudla asetshenziswayo avumelana nezimo ngokuvamile akhiwa izingqimba ezimbili noma ngaphezulu zamafilimu ahlukene, ngokuvamile angahlukaniswa abe ungqimba lwangaphandle, ungqimba oluphakathi nendawo kanye nongqimba lwangaphakathi ngokwezikhundla zabo.
Yiziphi izidingo zokusebenza kwesendlalelo ngasinye samafilimu okupakisha ukudla asebenziseka kalula?Okokuqala nje, ifilimu yangaphandle ivamise ukuphrinta, imelana nokunwaya, futhi imelana nemidiya.Izinto ezisetshenziswa kakhulu zifaka i-OPA, i-PET, i-OPP, namafilimu ahlanganisiwe.Ifilimu yesendlalelo esimaphakathi ngokuvamile inemisebenzi efana nesithiyo, ukufiphaza okukhanyayo, nokuvikela ngokomzimba.Izinto ezisetshenziswa kakhulu zifaka i-BOPA, i-PVDC, i-EVOH, i-PVA, i-PEN, i-MXD6, i-VMPT, i-AL, njll. Bese kuba nefilimu yangaphakathi, ngokuvamile enemisebenzi yokuvimbela, ukuvala, kanye ne-anti-media.Izinto ezisetshenziswa kakhulu yi-CPP, i-PE, njll. Ngaphezu kwalokho, ezinye izinto zinezingqimba zangaphandle kanye nesendlalelo esiphakathi.Isibonelo, i-BOPA ingasetshenziswa njengesendlalelo sangaphandle sokunyathelisa, futhi ingasetshenziswa njengesendlalelo esiphakathi ukuze idlale indima ethile yokuvimbela nokuvikela ngokomzimba.
Izici zefilimu zokupakisha eziguquguqukayo ezivame ukusetshenziswa, ngokuvamile, ungqimba lwangaphandle kufanele lube nokumelana nokuklwebheka, ukumelana nokubhoboza, ukuvikelwa kwe-UV, ukumelana nokukhanya, ukumelana nowoyela, ukumelana ne-organic matter, ukumelana nokushisa nokubanda, ukumelana nokuqhekeka kwengcindezi, ukuphrinta, ukushisa okuzinzile, iphunga eliphansi, eliphansi Elingenaphunga, elingenabuthi, elicwebezelayo, elisobala, eline-shading kanye nochungechunge lwezakhiwo;ungqimba oluphakathi nendawo ngokuvamile kufanele lube nokumelana nomthelela, ukumelana nokucindezela, ukumelana nokubhoboza, ukumelana nomswakama, ukumelana negesi, ukugcinwa kwephunga elimnandi, ukumelana nokukhanya, ukumelana nowoyela, ukumelana nezinto eziphilayo, ukumelana nokushisa nokubanda, ukumelana nokuqhekeka kwengcindezi, amandla ayinhlanganisela anezinhlangothi ezimbili, ukunambitheka okuphansi, iphunga eliphansi, elingenabuthi, elisobala, elingenakukhanya nezinye izakhiwo;khona-ke impahla yesendlalelo sangaphakathi, ngaphezu kwezinye izici ezivamile ezinongqimba lwangaphandle kanye nongqimba oluphakathi, nayo inezindawo zayo eziyingqayizivele, okufanele zibe nokugcinwa kwe-Fragrance, i-adsorption ephansi kanye nezakhiwo eziphikisana ne-seepage.Intuthuko yamanje yezikhwama zokupakisha ukudla imi kanje:
1. Izikhwama zokupakisha ukudla ezenziwe ngezinto ezivikela imvelo.
2. Ukuze kwehliswe izindleko futhi wonge izinsiza, izikhwama zokupakisha ukudla ziya ziba mncane.
3. Izikhwama zokupakisha zokudla ziyathuthuka ngendlela yemisebenzi ekhethekile.Izinto ezihlanganisiwe ezinezithiyo eziphezulu zizoqhubeka nokwandisa umthamo wemakethe.Ngokuzayo, amafilimu anezithiyo eziphezulu anezinzuzo zokucutshungulwa okulula, ukusebenza kwe-oksijini enamandla kanye nokusebenza komnqamulajuqu wamanzi, kanye nempilo yeshelufu ethuthukisiwe azoba inkomba yokupakishwa kokudla okuguquguqukayo ezitolo ezinkulu esikhathini esizayo.
