Ukuvalelwa kwamanzi luphawu olubalulekileyo kwiinkqubo ezininzi zekhebula, ngakumbi ezo zisetyenziswa kwiindawo ezinzima. Injongo yokuvalwa kwamanzi kukuthintela ukungena kwamanzi kwikhebula kwaye kubangele umonakalo kwii-conductor zombane ngaphakathi. Enye yezona ndlela zisebenzayo zokufezekisa ukuvinjelwa kwamanzi kukusebenzisa iintambo zokuthintela amanzi kulwakhiwo lwekhebula.
Imisonto yokuvalela amanzi iqhele ukwenziwa ngesixhobo se-hydrophilic esidumba xa sidibana namanzi. Oku kudumba kudala umqobo othintela amanzi ukuba angangeni kwintambo. Izinto ezisetyenziswa ngokuqhelekileyo ziyi-polyethylene (EPE), i-polypropylene (PP), kunye ne-sodium polyacrylate (SPA).
I-EPE yi-low density, high-molecular-weight- polyethylene ene-absorbency egqwesileyo yamanzi. Xa iintsinga ze-EPE zidibana namanzi, zifunxa amanzi kwaye zandise, zenze itywina elingangeni manzi elijikeleze abaqhubi. Oku kwenza i-EPE ibe yimpahla egqwesileyo yokuthintela imisonto yamanzi, njengoko ibonelela ngezinga eliphezulu lokukhusela ekungeneni kwamanzi.
I-PP yenye into esetyenziswa rhoqo. Iifiber zePP ziyi-hydrophobic, oku kuthetha ukuba zigxotha amanzi. Xa isetyenziswe kwintambo, iifayili zePP zenza umqobo othintela amanzi ukuba angangeni kwikhebula. Iintsinga zePP ziqhele ukusetyenziswa ngokudityaniswa neentsinga ze-EPE ukunika umaleko owongezelelweyo wokhuselo ekungeneni kwamanzi.
I-polyacrylate ye-sodium yi-polymer ephezulu kakhulu esetyenziswa rhoqo. Iifiber ze-sodium polyacrylate zinomthamo ophezulu wokufunxa amanzi, okwenza kube ngumqobo osebenzayo ngokuchasene nokungena kwamanzi. Iintsinga zifunxa amanzi kwaye zandise, zenze isitywina esingenamanzi esijikeleze abaqhubi.
Imisonto yokuthintela amanzi ngokuqhelekileyo ifakwe kwikhebula ngexesha lenkqubo yokuvelisa. Ngokuqhelekileyo zongezwa njengomaleko ojikeleze ii-conductor zombane, kunye nezinye izinto ezifana nokugquma kunye nejacketing. Iimveliso zibekwe kwiindawo ezicwangcisiweyo ngaphakathi kwentambo, njengasekupheleni kwentambo okanye kwiindawo ezithintekayo ekungeneni kwamanzi, ukubonelela ngomgangatho ophezulu wokukhusela emonakalweni wamanzi.
Ukuqukumbela, iintambo zokuvala amanzi ziyinxalenye ebalulekileyo ekwakhiweni kwekhebula kwizicelo ezifuna ukukhuselwa ekungeneni kwamanzi. Ukusetyenziswa kweentambo zokuthintela amanzi, ezenziwe kwizinto ezifana ne-EPE, i-PP, kunye ne-polyacrylate ye-sodium, inokubonelela ngomqobo osebenzayo ngokuchasene nomonakalo wamanzi, ukuqinisekisa ukuthembeka kunye nobude bekhebula.
