Ukuvimba amanzi kuyisici esibalulekile ekusetshenzisweni kwezintambo eziningi, ikakhulukazi lezo ezisetshenziswa ezindaweni ezinzima. Inhloso yokuvimba amanzi ukuvimbela amanzi ukuthi angangeni entamboni futhi abangele umonakalo kubaqhubi bakagesi abangaphakathi. Enye yezindlela eziphumelela kakhulu zokufeza ukuvimba kwamanzi ukusebenzisa izintambo zokuvimba amanzi ekwakhiweni kwezintambo.
Izindwangu zokuvimba amanzi ngokuvamile zenziwe ngezinto ezinamathela emanzini ezivuvukalayo uma zihlangana namanzi. Lokhu kuvuvukala kudala isithiyo esivimbela amanzi ukuthi angangeni ekhebulani. Izinto ezisetshenziswa kakhulu yi-polyethylene enwebekayo (EPE), i-polypropylene (PP), kanye ne-sodium polyacrylate (SPA).
I-EPE iyi-polyethylene enesisindo esincane, enesisindo sama-molecule amaningi enokumuncwa kwamanzi okuhle kakhulu. Lapho imicu ye-EPE ihlangana namanzi, imunca amanzi bese ikhula, idale uphawu olungangeni manzi oluzungeze ama-conductor. Lokhu kwenza i-EPE ibe yinto enhle kakhulu yezintambo ezivimba amanzi, njengoba inikeza izinga eliphezulu lokuvikela ekungeneni kwamanzi.
I-PP ingenye into evame ukusetshenziselwa yona. Imicu ye-PP ayithandi amanzi, okusho ukuthi iyawaxosha amanzi. Uma isetshenziswa kukhebula, imicu ye-PP idala isithiyo esivimbela amanzi ukuthi angene kukhebula. Imicu ye-PP ivame ukusetshenziswa ngokuhlanganiswa nemicu ye-EPE ukuze inikeze ungqimba olwengeziwe lokuvikela ekungeneni kwamanzi.
I-Sodium polyacrylate iyi-polymer emunca kakhulu evame ukusetshenziswa. Imicu ye-Sodium polyacrylate inamandla aphezulu okumunca amanzi, okwenza ibe yisithiyo esisebenzayo ekungeneni kwamanzi. Imicu imunca amanzi futhi ikhule, idale uphawu olungangeni manzi oluzungeze iziqhubi.
Izindwangu zokuvimba amanzi zivame ukufakwa kukhebula ngesikhathi senqubo yokukhiqiza. Ngokuvamile zengezwa njengengqimba ezungeze iziqhubi zikagesi, kanye nezinye izingxenye ezifana nokushisa nokufaka ijakhethi. Imikhiqizo ibekwa ezindaweni eziqondile ngaphakathi kwekhebula, njengasemaphethelweni ekhebula noma ezindaweni ezivame ukungena amanzi, ukuze kunikezwe izinga eliphezulu lokuvikelwa ekulimaleni kwamanzi.
Ekuphetheni, izindwangu zokuvimba amanzi ziyingxenye ebalulekile ekwakhiweni kwekhebula kwezicelo ezidinga ukuvikelwa ekungeneni kwamanzi. Ukusetshenziswa kwezindwangu zokuvimba amanzi, ezenziwe ngezinto ezifana ne-EPE, i-PP, kanye ne-sodium polyacrylate, kunganikeza isithiyo esisebenzayo ngokumelene nomonakalo wamanzi, okuqinisekisa ukuthembeka nokuqina kwekhebula.
