Kunezinhlobo eziningi zezikhwama zokupakisha zokudla ezisetshenziselwa ukupakishwa kokudla, futhi zinokusebenza kwazo okuhlukile nezimpawu. Namuhla sizoxoxa ngolwazi oluthile lokupakisha lokudla okuvame ukusetshenziswa kwesethenjwa sakho. Ngakho-ke siyini isikhwama sokupakisha ukudla? Izikhwama zokupakisha zokudla zivame ukubhekisela ku-plastics yeshidi ngobukhulu obungaphansi kuka-0.25mm njengamafilimu, futhi ukufakwa okuguqukayo okwenziwe ngamafilimu epulasitiki asetshenziswa kabanzi embonini yokudla. Kunezinhlobo ezahlukahlukene zezikhwama zokupakisha zokudla. Zisobala, zivumelana nezimo, zinokumelana namanzi amahle, ukumelana komswakama kanye nezindawo ezinhle zomshini wegesi, amandla amahle emishini, ukumelana namakhemikhali, okulula ukuphrinta kahle, futhi kungabekwa uphawu oluncane ukwenza izikhwama. Ngaphezu kwalokho, ukufakwa okuvame ukusetshenziswa kokudla okuguquguqukayo kuvame ukwakhiwa izingqimba ezimbili noma ngaphezulu zamafilimu ahlukene, ahlukaniswe ngokuvamile ahlukaniswe ngongqimba olungaphandle, ungqimba oluphakathi kanye nongqimba lwangaphakathi ngokwesikhundla.
Yiziphi izidingo zokusebenza kwesendlalelo ngasinye samafilimu ajwayelekile asetshenziswa ngokudla okuguqukayo? Okokuqala, ifilimu yangaphandle ivame ukuphrinta, ilwa phansi, imelana ne-medium. Izinto ezisetshenziswayo ezivame ukusetshenziswa yi-OPA, isilwane, i-OPP, ifilimu elihlanganisiwe, njll. Ifilimu eliphakathi nendawo linemisebenzi enjengesithiyo, isithunzi, nokuvikelwa ngokomzimba. Izinto ezisetshenziswayo ezisetshenziswayo zifaka i-bopa, i-PVDC, e-Evoh, i-PVA, ipeni, i-MXD6, i-vmpet, i-AL, i-Interner film, ngokuvamile inemisebenzi yesithiyo, ukubekwa uphawu, kanye nama-anti-media. Izinto ezisetshenziswa kakhulu yi-CPP, PE, njll. Ngaphezu kwalokho, ezinye izinto zokwenziwa zinomsebenzi ohlanganyelwe wesendlalelo sangaphandle kanye nongqimba oluphakathi. Isibonelo, i-BOPA ingasetshenziswa njengesendlalelo sangaphandle nesendlalelo sangaphakathi, futhi nayo ingasetshenziswa njengesendlalelo esiphakathi sokudlala isithiyo esithile nokuvikelwa ngokomzimba.
Izici zefilimu ezijwayelekile ezisetshenziswayo zokupakisha, ngokuvamile zikhuluma, izinto zangaphandle kufanele zihlukaniswe ukumelana, ukumelana, ukumelana, ukumelana, ukumelana, ukumelana, ukumelana, ukuvezwa, ukubonwa, ukucaca, ukucaca, ukuvela komoya Into ephakathi nendawo ephakathi inomthelela wokumelana, ukumelana nokucindezela, ukumelana nokubhoboza, ukumelana komswakama, ukumelana nokukhanya, ukumelana kwamafutha, ukumelana nokushisa, ukumelana nokushisa. , ukumelana nokuqhekeka kwengcindezi, amandla ahlanganisiwe ahlangene, iphunga eliphansi, iphunga eliphansi, elingelona elinobufakazi, obucacile, nobufakazi obukhanyayo kanye nezinye izakhiwo; Ngemuva kwalokho impahla yangaphakathi, ngaphezu kwezinye izakhiwo ezivamile ezinongqimba lwangaphandle kanye nesendlalelo esiphakathi, futhi inezakhiwo zayo ezihlukile, kufanele ibe nokugcinwa kwamakha, ama-adsorption aphansi kanye nokungaphelele. Ukuthuthukiswa kwamanje kwezikhwama zokupakisha zokudla kungokulandelayo: 1. Izikhwama zokupakisha zokudla ezenziwe ngezinto zokwakha imvelo. 2. Ukuze unciphise izindleko bese ugcine izinsiza, izikhwama zokupakisha zokudla zithuthuka ngokuncipha. I-3. Izikhwama zokupakisha zokudla zithuthuka ekusebenzeni okukhethekile. Izinto ezi-composite eziphakeme eziphakeme zizoqhubeka ukukhulisa umthamo wemakethe. Amafilimu anezithiyo eziphakeme nezinzuzo zokucubungula ezilula, umoya-mpilo onamandla we-oksijini kanye ne-water vapor barrier Properties, kanye nempilo ethuthukisiwe yeshelushe izoba yindawo esetshenziswayo yokudla okuguquguqukayo ngokuzayo.
