Njengamanje, ukusetshenziswa okuyinhloko kwe-downstreami-polyethyleneezweni lami zihlanganisa ifilimu, ukubumba umjovo, ipayipi, okungenalutho, umdwebo wezintambo, ikhebula, i-metallocene, i-coating nezinye izinhlobo eziyinhloko.
Eyokuqala ethwele kanzima, ingxenye enkulu yokusetshenziswa komfula ifilimu.Embonini yomkhiqizo wamafilimu, okujwayelekile ifilimu yezolimo, ifilimu yezimboni kanye nefilimu yokupakisha yomkhiqizo.Kodwa-ke, eminyakeni yamuva nje, izici ezifana nemingcele ezikhwameni zepulasitiki kanye nokuncipha okuphindaphindiwe kwesidingo ngenxa yalolu bhubhane ziye zabakhathaza ngokuphindaphindiwe, futhi babhekene nesimo esinamahloni.Isidingo semikhiqizo yamafilimu epulasitiki alahlwayo kancane kancane sizothathelwa indawo ukuthandwa kwamapulasitiki awonakele.Abakhiqizi abaningi bamafilimu nabo babhekene nezindlela ezintsha zobuchwepheshe bezimboni, futhi kancane kancane bathuthukela kumafilimu ezimboni angasebenza kabusha anekhwalithi nokusebenza okuqinile.Kodwa-ke, ngenxa yokonakala kwamafilimu epulasitiki awonakaliswayo, kunezidingo eziqinile zokupakishwa kwangaphandle, noma isidingo samafilimu okupakisha angaphandle adinga ukugcinwa isikhathi eside esidlule isikhathi sokuwohloka, futhi amafilimu ezimboni kanye neminye imikhakha ayikashintsheki, ngakho imikhiqizo yefilimu isazosetshenziswa.Kuye kwaba khona njengomkhiqizo oyinhloko phansi komfula we-polyethylene isikhathi eside, kodwa kungase kube nokwehla kokukhula kokusetshenziswa kanye nokwehla kwesilinganiso.
Ngaphezu kwalokho, izimboni ezinjengokubumba umjovo, amapayipi, nemigodi ehlobene eduze nokukhiqizwa nokuphila zizohlala ziyimikhiqizo eyinhloko yabathengi ezansi nomfula we-polyethylene eminyakeni embalwa ezayo, futhi zisazobuswa ingqalasizinda, izidingo zansuku zonke, namathuluzi omphakathi. kanye nemishini.Impilo yabantu ixhumene nempahla ehlala isikhathi eside, futhi isidingo sokuwohloka kwemikhiqizo siyehla.Inkinga enkulu ezibhekene nalezi zimboni ezingenhla okwamanje ukuthi izinga lokukhula komkhakha wezokuthengiswa kwezindlu limile kule minyaka edlule.Ngenxa yezinto ezifana nempendulo engemihle mayelana nokusetshenziswa kwezakhamuzi okulethwa izifo eziwumshayabhuqe eziphindaphindayo, ukuthuthukiswa kwemboni yemikhiqizo kubhekene nokumelana nokukhula okuthile.Ngakho-ke, uguquko lwengxenye yesikhathi esifushane lulinganiselwe, lungathinteki kancane emikhiqizweni ewohlokayo, imboni yamapayipi ingase ithinteke kakhulu ngezinqubomgomo, kuyilapho ukubunjwa komjovo kanye nemikhiqizo engenalutho kuthinteka kakhulu imizwa yokusetshenziswa kwezakhamuzi, kanye nezinga lokukhula. izokwehlisa ijubane esikhathini esizayo okungenzeka.
Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, ukusungulwa komuntu ngamunye kanye nokwenza abantu kwemikhiqizo yepulasitiki, kanye nokuqanjwa kwekhwalithi yomkhiqizo kanye nezidingo zokukhiqiza ezenziwe ngezifiso nakho kuthuthuka njalo.Ngakho-ke, esikhathini esizayo, imboni yemikhiqizo yepulasitiki izokwandisa isidingo sezinto ezithile zokusetshenziswa ezithuthukisa ukusebenza kwemikhiqizo yepulasitiki, njenge-metallocenes, amapulasitiki aginqikayo, izinto zokumboza kanye neminye imikhiqizo enenani eliphakeme noma imikhiqizo enezidingo ezihlukile emikhakheni ekhethekile. .Ngaphezu kwalokho, ngenxa yokukhiqizwa okugxilile kwamabhizinisi okukhiqiza i-polyethylene enhla nomfula eminyakeni yamuva, okuholele ekuguquguqukeni okukhulu komkhiqizo, futhi ukungqubuzana phakathi kweRussia ne-Ukraine phakathi nonyaka kubangele amanani aphezulu kawoyela ukuthi anyuse inzuzo ye-ethylene, kanye nokwanda kwezindleko. futhi ukunikezwa kuholele ekufaniseni komkhiqizo okungathi sína.Ngaphansi kwesimo samanje, Abakhiqizi be-polyethylene basebenza kakhulu ekukhiqizeni imikhiqizo ephezulu ye-value-added efana ne-metallocenes, ukubunjwa okujikelezayo, kanye nama-coatings, ngokuhambisana nokuthuthukiswa kwezimboni ezingezansi.Ngakho-ke, izinga lokukhula kwemikhiqizo lingase lenyuke ngezinga elithile esikhathini esizayo.
Ngaphezu kwalokho, njengoba lolu bhubhane luqhubeka ngokuphindaphindiwe, kanye nokucwaninga nokuthuthukiswa kwemikhiqizo emisha ngabakhiqizi, imicu ye-polyethylene, izinto ezikhethekile zomkhiqizo wezokwelapha nezokuvikela nazo zilandelwa kancane kancane futhi zathuthukiswa, futhi isidingo sesikhathi esizayo sizokhula kancane kancane.
