Ekuphileni kwethu kwansuku zonke, izinkomishi zephepha ziye zaba yinto evamile.Noma ngabe isitolo sekhofi, indlu yetiye noma umbuthano womndeni, sonke sisebenzisa izinkomishi zephepha.Kodwa-ke, ingabe wake wazibuza ukuthi kungani lezi zinkomishi zephepha ziqinisekisiwe ukuthi ngeke zivuze?Konke lokhu kungenxa yento eluhlaza yenkomishi yephepha - iphepha eliboshwe nge-PE.
I-PE camera roll rolliwumkhiqizo wephepha ocutshungulwayo ombozwe ungqimba lwefilimu ye-polyethylene ephepheni lesisekelo.Umsebenzi walolu ngqimba lwefilimu ukuthuthukisa ukusebenza okungangeni kwamanzi kwendebe yephepha, futhi uthuthukise ukumelana nokushisa namandla enkomishi yephepha.Ngakho-ke, iphepha eliboshwe nge-PE liqinisekisa kanjani ukuthi inkomishi yephepha ayivuzi?
Okokuqala, ukukhethwa kwezinto ezibonakalayo zephepha elihlanganisiwe le-PE kubaluleke kakhulu ekusebenzeni kwalo okungangeni manzi.Ifilimu ye-polyethylene iyi-resin yokwenziwa enesisindo esikhulu samangqamuzana, esebenza kahle kakhulu ekungangeni kwamanzi futhi ingavimbela ngokuphumelelayo umswakama ukuthi ungangeni ngaphakathi kwendebe yephepha.Ngesikhathi esifanayo, iphepha elihlanganisiwe le-PE liye laphathwa ngokukhethekile ukwenza inhlanganisela phakathi kwefilimu nephepha ngokuqinile, ngaleyo ndlela igweme ukungena kwamanzi.
Okwesibili, ubuchwepheshe bokucubungula iphepha elihlanganisiwe le-PE nalo lidlala indima ebalulekile ekusebenzeni kwalo okungangeni manzi.Phakathi nenqubo yokukhiqiza, umshini wokukhipha i-laminating ngokulinganayo ufafaza ifilimu ye-polyethylene encibilikisiwe ephepheni lesisekelo ngokusebenzisa umoya ophezulu wengcindezi.Le ndlela yokucubungula yakha isibopho esiqinile phakathi kwefilimu nephepha, ngaleyo ndlela iqinisekisa ukusebenza okungangeni kwamanzi kwenkomishi yephepha.
Okokugcina, ukuze kuqhutshekwe nokuqinisekisa ukuthi izinkomishi zephepha azinawo amanzi, ukuhlolwa okuqinile nokulawula kuyadingeka ngesikhathi sokucutshungulwa kwabalandeli benkomishi yephepha.Isibonelo, imiphetho yezinkomishi zephepha idinga ukusikwa kahle futhi igaywe ukuze kuqinisekiswe uphawu oluhle.Ngesikhathi esifanayo, ikhwalithi yezinkomishi zephepha idinga ukuhlolwa ngokungahleliwe phakathi nenqubo yokukhiqiza ukuze kuqinisekiswe ukuthi zihlangabezana nezindinganiso zekhwalithi ezifana nokumelana kwamanzi, ukumelana nokushisa, namandla.
Ngezici zayo zezinto ezibonakalayo eziyingqayizivele kanye nenqubo yokumboza yobungcweti, iphepha elihlanganisiwe le-PE liqinisekise ngempumelelo umsebenzi ongangenisi amanzi wenkomishi yephepha.Ukusebenza kwayo okungangeni manzi, ukuqina, ukuphepha kanye nokusetshenziswa kabusha kwenza iphepha eliboshwe nge-PE libe yisinqumo esifanelekile sokusetshenziswa kabanzi ekwenzeni inkomishi yephepha.
