1. Ukusebenza kanye nokusetshenziswa kwe-PVDC:
Imboni yepulasitiki yamazwe ngamazwe isetshenziselwa ukusebenzisa inani elibonakalayo lokungena ukuze kubonakale umehluko ekusebenzeni kanye nezinto ezikwazi ukungena komoyampilo ngaphansi kwe-10 zibizwa.high barrier materials.I-10 ~ 100 ibizwa ngokuthi i-medium barrier materials.Ngaphezu kwe-100 ibizwa ngokuthi i-barrier material evamile.Njengamanje, laba abathathu babonilehigh barrier materialsemhlabeni kukhona i-PVDC, i-EVOH ne-PAN.Izinto ezintathu zonke zingama-copolymer.Umgoqo we-oxygen we-EVOH ungcono kune-PVDC futhi owe-PVDC ungcono kune-PAN;Ngokuvimbela umhwamuko wamanzi, i-EVOH ingcono kune-PVDC, futhi i-PVDC ingcono kune-PAN.Kodwa-ke, ngaphansi kwezimo zomswakama ophezulu, isakhiwo se-molecular EVOH siqukethe - iqembu le-OH, elilula kakhulu ukumunca umswakama, futhi ukusebenza kwayo kwesithiyo kuzoncishiswa kakhulu.Ngasikhathi sinye, ukusebenza kwesithiyo se-PAN nakho kwehla kakhulu ngokwanda komswakamo wendawo.I-PVDC iyindlela engcono kakhulu yokuvimbela ukusebenza kweizinto zokupakisha zepulasitikiemhlabeni.
I-Polyvinylidene chloride resin (PVDC) iyi-copolymer ene-vinylidene chloride monomer njengengxenye eyinhloko.Kuyinto efanelekile yokupakisha enesithiyo esiphezulu, ukuqina okuqinile, ukuncipha okuhle kakhulu kokushisa kanye nokuzinza kwamakhemikhali kanye nezakhiwo ezinhle kakhulu zokuphrinta nezokuvala ukushisa.Isetshenziswa kabanzi ekudleni, kwezokwelapha, kwezempi nakweminye imikhakha.
Ukuthuthukisa imikhiqizo ye-PVDC egcwele ubuchwepheshe obuphezulu kubaluleke kakhulu ukulinganisa izinsiza ze-chlorine embonini ye-chlor-alkali futhi kuthuthukise kakhulu ukusebenza kahle kwebhizinisi nokuncintisana.I-PVDC inesakhiwo esihle kakhulu sokuvimbela njengempahla yokupakisha.Ukusebenzisa i-PVDC ukupakisha ukudla kungandisa kakhulu isikhathi seshelufu, futhi ngesikhathi esifanayo, kunomphumela omuhle kakhulu wokuvikela embala, iphunga kanye nokunambitheka kokudla.Ukufakwa kwenhlanganisela ye-PVDC kunokusetshenziswa kwensiza yeyunithi ephansi kunefilimu evamile ye-PE, iphepha, izinkuni,i-aluminium foilnezinye izinto zokupakisha.Umthamo wemfucuza yokupakishwa wehliswe kakhulu futhi izindleko seziphelele zehlisiwe, ukuze kufezwe inhloso yokunciphisa ukupakisha.
I-PVDC isetshenziswa kakhulu emazweni asentshonalanga, ehlanganisa ukudla, amakhemikhali, izimonyo, imithi, i-hardware kanye nemikhiqizo yemishini, futhi yaziwa ngokuthi izinto zokupakisha "eziluhlaza".Ukusetshenziswa kwe-PVDC kuhlobene nezinga lokuphila likazwelonke.Njengamanje, ukusetshenziswa konyaka kwe-PVDC kungamathani ayi-50000 emazweni aseMelika kanye namathani angama-45000 eYurophu, kanye nesamba esingamathani angama-40000 e-Asia nase-Australia.Izinga lokukhula elijwayelekile lonyaka lokusetshenziswa kwemakethe ye-PVDC eYurophu, eMelika naseJapan yi-10%.Emazweni aseMelika, amathani angaphezu kuka-15000 we-PVDC resin asetshenziselwaukufakwa kwe-vacuumyezingcezu ezinkulu zenyama entsha unyaka ngamunye, futhi ukusetshenziswa kwe-PVDC enamathela ephepheni kubala u-40% wesamba esisetshenziswa i-PVDC.E-Japan naseNingizimu Korea, inani elikhulu lezinto zokupakisha ze-PVDC zisetshenziswa ekudleni, emithini, emikhiqizweni yamakhemikhali nasezintweni zokupakisha zemikhiqizo ye-elekthronikhi.Ukusetshenziswa konyaka kwe-PVDC resin kungaphezu kwamathani ayi-10000 kuphela ngefilimu yepulasitiki.
