Izinkomishi zephepha ziyizinto ezivame ukulahlwa empilweni yethu. Njengamanje, izinto zokusetshenziswa ezivamile zendebe yephepha zifaka iphepha elimbozwe nge-PE, iphepha elimbozwe nge-PLA kanye nephepha lendebe elingenapulasitiki. indebe yephepha izinto zokusetshenziswa zinezinzuzo nezinkinga zazo maqondana nokuvikelwa kwemvelo, ukuwohloka, kanye nezindleko zokukhiqiza.
1. Izinzuzo zephepha elimbozwe nge-PE
Iphepha elimbozwe nge-PE liyimpahla eluhlaza yezinkomishi zephepha ezimbozwe ngefilimu ye-polyethylene ebusweni bephepha. Inzuzo ukuthi linokumelana okuhle kwamanzi, okungavimbela ngempumelelo ukungena koketshezi, ukuze indebe yephepha ingabi lula ukuvuza ngezinga elithile.
Ngaphezu kwalokho, izindleko zokukhiqiza ze Umqulu wephepha ombozwe nge-PE iphansi kakhulu, futhi ubuchwepheshe bokucubungula bulula, okwenza kube okushibhile, okufanele ukukhiqizwa nokusetshenziswa ngezinga elikhulu.
Ukungalungi
Njengoba i-PE iyinto yepulasitiki, ukusetshenziswa kwezinkomishi zephepha ezimbozwe nge-PE kuzokwandisa ukukhiqizwa kwemfucuza yepulasitiki futhi kubangele umthwalo emvelweni.
Ngenxa yokuhlanganiswa kwefilimu nephepha le-PE, ukubuyiswa kanye nokusetshenziswa kabusha kwezinkomishi zephepha kuba nzima, futhi ukulahlwa okungafanele kungabangela ukungcola emvelweni.
2. Izinzuzo zephepha elimbozwe nge-PLA
Iphepha elimbozwe yi-PLA limbozwe ngefilimu ye-polylactic acid (PLA) ebusweni bephepha. I-PLA iyipulasitiki ebolayo eyenziwe ngezinto zokusetshenziswa zezitshalo, enobungani nemvelo kakhulu kunezinto zepulasitiki zendabuko. Ngemva kokuba izinkomishi zephepha zilahliwe, zingabola zibe izinto ezingenabo ubuthi futhi ezingenangozi ngemva kokwelashwa okufanele, okuyinto enobungani nemvelo.
I-PLA yenziwe ngezinsiza ezivuselelekayo njengesitashi sezitshalo futhi ayincikile kakhulu ezinsizeni ze-petrochemical, okusiza ukunciphisa isidingo sezinsiza ezingavuseleleki.
Ukungalungi
Ngenxa yokulinganiselwa kwenqubo yokukhiqiza kanye nezindleko zezinto zokusetshenziswa, iphepha elimbozwe nge-PLA libiza kakhulu futhi intengo yemakethe iphezulu, ngakho-ke alifaneleki ukukhiqizwa okukhulu nokungabizi kakhulu.
Ukubola kwe-PLA kudinga izimo ezithile zokushisa nomswakama. Uma imfucuza ingaphathwa ngaphansi kwezimo ezifanele, izinzuzo zayo zemvelo zizoba buthaka.
3. Izinzuzo zephepha elingenapulasitiki
Iphepha elingenapulasitiki libhekisela ezintweni zokusetshenziswa zezinkomishi zephepha ngaphandle kokwengeza noma yikuphi ukugqoka kwepulasitiki. Inzuzo ukuthi linobungani nemvelo ngokuphelele, lonakala ngokuphelele, futhi alinawo umthelela omubi emvelweni.
Ngesikhathi esifanayo, iphepha elingenapulasitiki lisebenzisa ubuchwepheshe obukhethekile bokungangenisi manzi ukuze lenze libe nokusebenza okuthile okungangenisi manzi, okungahlangabezana nezidingo zokusetshenziswa kwansuku zonke.
Ukungalungi
Uma kuqhathaniswa nephepha elimbozwe nge-PE kanye nephepha elimbozwe nge-PLA, iphepha elingenapulasitiki linokumelana okuncane kokungena kwamanzi, futhi izinkinga zokuvuza zingase zenzeke uma lisetshenziswa noma lishiywa isikhathi eside.
Njengamanje, ubuchwepheshe bokukhiqiza iphepha elimboziwe elingenapulasitiki busesesigabeni sokuthuthukiswa, inqubo yokukhiqiza iyinkimbinkimbi kakhulu, futhi izindleko zokukhiqiza ziphakeme kakhulu, okwenza intengo yalo ibe phezulu kakhulu, okungafanele ukukhuthazwa nokusetshenziswa ngezinga elikhulu.
Izinto zokusetshenziswa zendebe yephepha ezahlukene zinezinzuzo nezinkinga zazo. Lapho kukhethwa izinto zokusetshenziswa zendebe yephepha, izici zezinto zokusetshenziswa ezahlukene kanye nezidingo zokusetshenziswa kwangempela kufanele kucatshangelwe ngokuphelele, ukuze kulinganiswe ukuvikelwa kwemvelo kanye nezinzuzo zomnotho, futhi kulwelwe ukunciphisa umthelela emvelweni. Ngesikhathi esifanayo, intuthuko eqhubekayo kanye nokusungula izinto ezintsha kwesayensi nobuchwepheshe kuzoletha nezinto zokusetshenziswa zendebe yephepha ezingcono, okuhambisana kakhulu nomqondo wentuthuko esimeme.
