Kunezinhlobo eziningi zezikhwama zokupakisha ukudla ezisetshenziselwa ukupakisha ukudla, futhi zinokusebenza kwazo okuhlukile nezici.Namuhla sizoxoxa ngolwazi lwesikhwama sokupakisha ukudla esivame ukusetshenziswa ukuze uthole inkomba yakho.Ngakho siyini isikhwama sokupakisha ukudla?Izikhwama zokufaka ukudla ngokuvamile zibhekisela kumapulastiki eshidi anogqinsi olungaphansi kuka-0.25mm njengamafilimu, futhi ukupakishwa okuguquguqukayo okwenziwe ngamafilimu epulasitiki asetshenziswa kakhulu embonini yokudla.Kunezinhlobo ezahlukene zezikhwama zokupakisha ukudla.Ziyabonakala, ziguquguqukayo, zinokumelana okuhle kwamanzi, ukumelana nomswakama kanye nezindawo zokuvimbela igesi, amandla amahle omshini, izakhiwo zamakhemikhali ezinzile, ukumelana nowoyela, ukuphrinta kalula, futhi kungenziwa kuvalwa ukushisa ukuze kwenziwe izikhwama.Ngaphezu kwalokho, ukupakishwa okuguquguqukayo kokudla okuvame ukusetshenziswa ngokuvamile kuvame ukwakhiwa kwezingqimba ezimbili noma ngaphezulu zamafilimu ahlukene, okungahle kuhlukaniswe ungqimba olungaphandle, ungqimba oluphakathi nendawo kanye nolwendlalelo lwangaphakathi ngokwendawo.
Yiziphi izidingo zokusebenza kwesendlalelo ngasinye samafilimu okupakisha asebenziseka kalula okudla?Okokuqala nje, ifilimu yangaphandle ivamise ukuphrinta, imelana nokunwaya, futhi imelana nendawo.Izinto ezisetshenziswa kakhulu yi-OPA, i-PET, i-OPP, ifilimu eboshiwe, njll. Ifilimu yesendlalelo esimaphakathi ngokuvamile inemisebenzi efana nesithiyo, ukufiphaza, 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 yongqimba yangaphakathi, ngokuvamile enemisebenzi yokuvimbela, ukuvala, kanye ne-anti-media.Izinto ezisetshenziswa kakhulu yi-CPP, PE, njll. Ngaphezu kwalokho, ezinye izinto zinomsebenzi ohlangene wengqimba yangaphandle kanye nesendlalelo esiphakathi.Isibonelo, i-BOPA ingasetshenziswa njengesendlalelo sangaphandle kanye nesendlalelo sangaphakathi, futhi ingasetshenziswa njengesendlalelo esiphakathi ukuze idlale umgoqo othile nokuvikelwa ngokomzimba.
Izici zefilimu zokupakisha eziguquguqukayo ezivame ukusetshenziswa, ngokuvamile, izinto zangaphandle kufanele zibe nokumelana nokuklwebheka, ukumelana nokubhoboza, ukumelana ne-UV, ukumelana nokukhanya, ukumelana nowoyela, ukumelana ne-organic, ukumelana nokubanda, ukumelana nokucindezeleka kokuqhekeka, ukuphrinta, ukuzinza kokushisa, iphunga eliphansi, eliphansi. Uchungechunge lwezakhiwo ezifana nephunga, ukungabi nobuthi, ukucwebezela, ukucaca, ukuthungatha, njll.;ungqimba oluphakathi nendawo ngokuvamile lunokumelana nomthelela, ukumelana nokucindezela, ukumelana nokubhoboza, ukumelana nomswakama, ukumelana negesi, ukugcinwa kwephunga elimnandi, ukumelana nokukhanya, ukumelana nowoyela, ukumelana nemvelo, ukumelana nokushisa kanye nokumelana nokubanda., ukumelana nokuqhekeka kwengcindezi, amandla ahlanganisiwe anezinhlangothi ezimbili, iphunga eliphansi, iphunga eliphansi, elingenabuthi, elisobala, elingenakukhanya nezinye izakhiwo;ke ungqimba lwangaphakathi impahla, ngaphezu kwezinye izici ezivamile nge ungqimba lwangaphandle kanye ungqimba oluphakathi, futhi has izici zayo siqu esiyingqayizivele, kumele kube Ukugcinwa Iphunga, adsorption ongaphakeme futhi impermeability.Intuthuko yamanje yezikhwama zokupakisha ukudla imi kanje: 1. Izikhwama zokupakisha ukudla ezenziwe ngezinto ezivikela imvelo.2. Ukuze kwehliswe izindleko nokongiwa kwezinsiza, izikhwama zokupakisha ukudla zithuthukela ekuncipheni.3. Izikhwama zokupakisha ukudla zithuthukela ekusebenzeni okukhethekile.Izinto ezihlanganisiwe ezinezithiyo eziphezulu zizoqhubeka nokwandisa umthamo wemakethe.Amafilimu anesithiyo esiphezulu anezinzuzo zokucutshungulwa okulula, i-oxygen enamandla kanye nezakhiwo zokuvimbela umhwamuko wamanzi, nempilo yeshelufu ethuthukisiwe izoba yinsakavukela yokupakisha ukudla kwasesitolo esikhulu esikhathini esizayo.
