Ukuvinjwa kwamanzi kuyisici esibalulekile sezinhlelo eziningi zekhebula, ikakhulukazi lezo ezisetshenziswa ezindaweni ezinokhahlo. Inhloso yokuvinjwa kwamanzi ukuvimbela amanzi ukuthi angangeni kukhebula futhi abangele umonakalo kumakhondatha kagesi ngaphakathi. Enye yezindlela eziphumelela kakhulu zokufeza ukuvinjelwa kwamanzi ngokusebenzisa izintambo zokuvimbela amanzi ekwakhiweni kwekhebula.
Izintambo ezivimba amanzi ngokuvamile zenziwe nge-hydrophilic material ekhukhumala lapho ihlangana namanzi. Lokhu kuvuvukala kudala umgoqo ovimbela amanzi ukuthi angangeni kukhebula. Izinto ezisetshenziswa kakhulu yi-polyethylene (EPE), i-polypropylene (PP), ne-sodium polyacrylate (SPA).
I-EPE iyi-polyethylene enesisindo esiphansi, enesisindo esikhulu samangqamuzana ene-absorbency enhle kakhulu yamanzi. Lapho imicu ye-EPE ihlangana namanzi, imunca amanzi futhi ande, yenze uphawu olungangeni manzi eduze kwamakhondakta. Lokhu kwenza i-EPE ibe yinto enhle kakhulu yezintambo zokuvimba amanzi, njengoba inikeza izinga eliphezulu lokuvikela ekungeneni kwamanzi.
I-PP ingenye impahla evame ukusetshenziselwa. Izintambo ze-PP ziyi-hydrophobic, okusho ukuthi zixosha amanzi. Uma isetshenziswa kukhebula, imicu ye-PP yenza umgoqo ovimbela amanzi ukuthi angangeni kukhebula. Imicu ye-PP ivamise ukusetshenziswa ekuhlanganisweni nemicu ye-EPE ukuze inikeze isendlalelo esengeziwe sokuvikela ekungeneni kwamanzi.
I-polyacrylate ye-sodium iyi-polymer e-superabsorbent evame ukusetshenziswa. Imicu ye-polyacrylate ye-sodium inamandla amakhulu okumunca amanzi, okuwenza abe umgoqo ophumelelayo wokulwa nokungena kwamanzi. Imicu imunca amanzi futhi yande, idale uphawu olungangeni manzi ezizungeze amakhondakta.
Izintambo zokuvimba amanzi zivame ukufakwa kukhebula phakathi nenqubo yokukhiqiza. Ngokuvamile zengezwa njengesendlalelo ezizungeze amakhondatha kagesi, kanye nezinye izinto ezifana nokufaka amajakhethi kanye nokufaka amajakhethi. Imikhiqizo ibekwe ezindaweni eziqondile ngaphakathi kwekhebula, njengasemikhawulweni yekhebula noma ezindaweni ezijwayele ukungena emanzini, ukuze kuhlinzekwe izinga eliphezulu lokuvikela emonakalweni wamanzi.
Sengiphetha, izintambo zokuvimba amanzi ziyingxenye ebalulekile ekwakhiweni kwekhebula lezinhlelo zokusebenza ezidinga ukuvikelwa ekungeneni kwamanzi. Ukusetshenziswa kwezintambo zokuvimbela amanzi, ezenziwe ngezinto ezifana ne-EPE, PP, ne-sodium polyacrylate, zinganikeza umgoqo ophumelelayo ngokumelene nokulimala kwamanzi, ukuqinisekisa ukuthembeka nokuphila isikhathi eside kwekhebula.
