Empilweni yethu yansuku zonke, izinkomishi zephepha seziyinto evamile. Kungakhathaliseki ukuthi kuyisitolo sekhofi, indlu yetiye noma umbuthano womndeni, sonke sisebenzisa izinkomishi zephepha. Kodwa-ke, wake wazibuza ukuthi kungani lezi zinkomishi zephepha ziqinisekisiwe ukuthi azivuzi? Konke lokhu kungenxa yenkomishi yephepha eyisihluthulelo yezinto zokusetshenziswa - iphepha elimbozwe nge-PE.
Umqulu wephepha ombozwe nge-PE iwumkhiqizo wephepha ocutshunguliwe ombozwe ungqimba lwefilimu ye-polyethylene ephepheni eliyisisekelo. Umsebenzi walolu ngqimba lwefilimu ukuthuthukisa ukusebenza okungangeni manzi kwendebe yephepha, kanye nokuthuthukisa ukumelana nokushisa kanye namandla endebe yephepha. Ngakho-ke, iphepha elimbozwe nge-PE liqinisekisa kanjani ukuthi indebe yephepha ayivuzi?
Okokuqala, ukukhethwa kwezinto ezisetshenziswa ephepheni elimbozwe yi-PE kubaluleke kakhulu ekusebenzeni kwalo okungangeni manzi. Ifilimu ye-polyethylene iyi-resin yokwenziwa enesisindo esikhulu sama-molecule, enekhono elihle kakhulu lokungangeni manzi futhi ingavimbela ngempumelelo umswakama ukuthi ungene ngaphakathi kwendebe yephepha. Ngesikhathi esifanayo, iphepha elimbozwe yi-PE nalo liphathwe ngokukhethekile ukuze kwenziwe inhlanganisela phakathi kwefilimu nephepha iqine kakhulu, ngaleyo ndlela kugwenywe ukungena kwamanzi.
Okwesibili, ubuchwepheshe bokucubungula iphepha elimbozwe nge-PE budlala indima ebalulekile ekusebenzeni kwalo okungangeni manzi. Ngesikhathi senqubo yokukhiqiza, umshini wokulamina ufafaza ngokulinganayo ifilimu ye-polyethylene encibilikisiwe ephepheni eliyisisekelo ngomoya ocindezelekile. Le ndlela yokucubungula yakha isibopho esiqinile phakathi kwefilimu nephepha, ngaleyo ndlela iqinisekisa ukusebenza okungangeni manzi kwendebe yephepha.
Okokugcina, ukuze kuqinisekiswe ukuthi izinkomishi zephepha azinamanzi, kudingeka ukuhlolwa okuqinile nokulawula ngesikhathi sokucubungula abalandeli bezinkomishi zephepha. Isibonelo, imiphetho yezinkomishi zephepha idinga ukunqunywa kahle futhi igaywe ukuqinisekisa ukuvalwa okuhle. Ngesikhathi esifanayo, ikhwalithi yezinkomishi zephepha idinga ukuhlolwa ngokungahleliwe ngesikhathi senqubo yokukhiqiza ukuqinisekisa ukuthi zihlangabezana nezindinganiso zekhwalithi njengokumelana namanzi, ukumelana nokushisa, kanye namandla.
Ngezici zayo ezihlukile zezinto ezibonakalayo kanye nenqubo yobuchwepheshe yokumboza, iphepha elimbozwe nge-PE liqinisekise ngempumelelo ukusebenza okungangeni manzi kwendebe yephepha. Ukusebenza kwalo okungangeni manzi, ukuqina, ukuphepha kanye nokuphindeka kabusha kwenza iphepha elimbozwe nge-PE libe yisinqumo esifanele sokusetshenziswa kabanzi ekukhiqizweni kwendebe yephepha.
