Izinkomishi zamanzi epulasitiki ziyizinto ezivamile ezisetshenziswa ekuphileni kwethu kwansuku zonke. Kubaluleke kakhulu ukukhetha izinto eziphephile. Okulandelayo isihloko mayelana nezinto zokuphepha zezinkomishi zamanzi epulasitiki.
Njengoba abantu benaka kakhulu impilo kanye nokuvikelwa kwemvelo, abathengi abaningi ngokwengeziwe banaka ukukhethwa kwezinto ezibonakalayo zezinkomishi zamanzi epulasitiki. Ukuphepha kungenye yezinto ezicatshangelwayo ezibaluleke kakhulu lapho ukhetha ibhodlela lamanzi epulasitiki. Lesi sihloko sizokwethula izinto ezimbalwa ezivamile zenkomishi yamanzi epulasitiki futhi sigxile ezindabeni zokuphepha.
Okokuqala, i-polyethylene (PE) iyinto evamile yenkomishi yamanzi epulasitiki. Inokuqina okuhle kokushisa okuphansi nokuphezulu futhi ayikhiphi izinto eziyingozi. Amabhodlela amanzi e-polyethylene angasetshenziselwa ukubamba iziphuzo ezishisayo noma ezibandayo futhi aphephe kakhulu futhi anokwethenjelwa. Ngaphezu kwalokho, i-polyethylene iyipulasitiki esetshenziswa kabusha futhi ihambisana nemvelo.
Okwesibili, i-polypropylene (PP) nayo iyinto evamile yenkomishi yamanzi epulasitiki. Ngokufanayo ne-polyethylene, i-polypropylene inokuqina okuphezulu kokushisa nokumelana namakhemikhali. Ngakho-ke, amabhodlela amanzi e-polypropylene nawo ayisinqumo esiphephile. Ngokunjalo, i-polypropylene nayo iyipulasitiki egaywa kabusha futhi ihambisana nemvelo.
Kodwa-ke, ezinye izinto zepulasitiki zingase zingafaneleki njengezinto zenkomishi yamanzi. Isibonelo, i-polyvinyl chloride (PVC) iyipulasitiki evamile, kodwa ingakhipha izinto eziyingozi njengama-plasticizers. Lawa makhemikhali angase abe yingozi empilweni yomuntu. Ngakho-ke, lapho ukhetha amabhodlela amanzi epulasitiki, zama ukugwema ukusebenzisa izinto ze-polyvinyl chloride.
Ngaphezu kwalokho, i-polystyrene (PS) iphinde ibe yinto evamile yepulasitiki, kodwa iyazwela ekushintsheni kwezinga lokushisa. I-Polystyrene ingase ikhiphe izinto eziyingozi emazingeni okushisa aphezulu, iyenze ingafaneleki iziphuzo ezishisayo. Nakuba amabhodlela amanzi e-polystyrene eshibhile ngokwenani, ngokombono wokuphepha, sincoma ukukhetha ezinye izinto.
Ngaphezu kwalokho, kunepulasitiki ebolayo ebizwa ngokuthi i-melamine (PLA), nayo esetshenziswe kabanzi ekwenzeni izinkomishi zamanzi zepulasitiki eminyakeni yamuva. I-PLA ikhiqizwa ngezinsiza ezivuselelekayo ezifana nesitashi sombila futhi iphephile futhi ayinangozi kubantu. Ngesikhathi sokusetshenziswa, izinkomishi zamanzi ze-PLA ngeke zikhiqize izinto eziyingozi noma zibangele ukungcoliswa kwemvelo. Ngakho-ke, amabhodlela amanzi e-PLA ayisinqumo esiphephe kakhulu futhi esivumelana nemvelo.
Okokugcina, akunandaba ukuthi ukhetha yiphi inkomishi yamanzi yepulasitiki, sincoma ukuthi ulandele izimiso zokusebenzisa nokunakekela ezilandelayo:
1. Ungavezi amabhodlela amanzi epulasitiki ezindaweni ezishisa kakhulu ukuze ugweme ukubola nokuqedwa kwezinto zepulasitiki.
2. Hlanza amabhodlela amanzi epulasitiki njalo ukuze ugweme ukungcola okuyinsalela nokukhula kwamagciwane.
3. Gwema ukusebenzisa okokuhlanza okuqinile ukuze ugweme ukuthikameza ukuphepha kwezinto zepulasitiki.
4. Uma inkomishi yamanzi ilimele noma isikhulile, kufanele ishintshwe ngesikhathi ukuze ugweme ukusebenzisa izinkomishi eziyingozi empilweni.
Ukufingqa, i-polyethylene ne-polypropylene yizinto ezivamile zamabhodlela epulasitiki aphephile, kuyilapho i-polyvinyl chloride ne-polystyrene kufanele kugwenywe ngangokunokwenzeka. Ngaphezu kwalokho, i-PLA ye-biodegradable yepulasitiki nayo iyisinqumo esiphephile nesihambisana nemvelo. Lapho ukhetha inkomishi yamanzi yepulasitiki, sicela unake ukuphepha kwezinto ezibonakalayo futhi ulandele imigomo efanele yokusetshenziswa nokugcinwa kwayo. Ngale ndlela, ungakhetha ibhodlela lamanzi lepulasitiki eliphephile nelithembekile futhi ujabulele impilo enempilo.
