Ukuvalwa kwamanzi luphawu olubalulekileyo kwiindlela ezininzi zokusetyenziswa kweentambo, ingakumbi ezo zisetyenziswa kwiindawo ezinzima. Injongo yokuvalwa kwamanzi kukuthintela amanzi ukuba angangeni kwintambo aze abangele umonakalo kwiikhontraktha zombane ezingaphakathi. Enye yezona ndlela zisebenzayo zokufezekisa ukuvalwa kwamanzi kukusebenzisa imisonto yokuvala amanzi ekwakheni iintambo.
Iintambo zokuvala amanzi zihlala zenziwe ngezinto ezihlala emanzini ezidumba xa zidibana namanzi. Oku kudumba kudala umqobo othintela amanzi ukuba angangeni kwintambo. Izinto ezisetyenziswa kakhulu yi-expandable polyethylene (EPE), i-polypropylene (PP), kunye ne-sodium polyacrylate (SPA).
I-EPE yi-polyethylene enobunzima obuphantsi, enobunzima beemolekyuli ezininzi enokufunxa amanzi kakuhle. Xa iifayibha ze-EPE zidibana namanzi, ziyafunxa amanzi kwaye zande, zenze isitywino esingangeni manzi esijikeleze ii-conductors. Oku kwenza i-EPE ibe yinto efanelekileyo kakhulu kwiintambo ezithintela amanzi, njengoko ibonelela ngokhuseleko oluphezulu ekungeneni kwamanzi.
I-PP yenye into esetyenziswa rhoqo. Iifayibha ze-PP azinamanzi, oko kuthetha ukuba ziyawagxotha amanzi. Xa zisetyenziswa kwintambo, iifayibha ze-PP zenza umqobo othintela amanzi ukuba angangeni kwintambo. Iifayibha ze-PP zihlala zisetyenziswa kunye neefayibha ze-EPE ukubonelela ngomaleko owongezelelweyo wokukhusela ekungeneni kwamanzi.
I-sodium polyacrylate yi-polymer efunxa kakhulu esetyenziswa rhoqo. Iifayibha ze-sodium polyacrylate zinamandla aphezulu okufunxa amanzi, nto leyo eyenza ukuba zibe ngumqobo osebenzayo ekungeneni kwamanzi. Iifayibha zifunxa amanzi kwaye zande, zenze isivalo esingangeni manzi sijikeleze ii-conductors.
Iintambo zokuthintela amanzi zihlala zifakwa kwintambo ngexesha lenkqubo yokwenziwa. Zihlala zongezwa njengomaleko ojikeleze ii-conductors zombane, kunye nezinye izinto ezifana nokuthintela ubushushu kunye nejakethi. Iimveliso zibekwa kwiindawo ezibalulekileyo ngaphakathi kwentambo, njengakwiziphelo zentambo okanye kwiindawo ezinokuthi zingene emanzini, ukuze zibonelele ngokhuseleko oluphezulu ekonakaleni kwamanzi.
Ukuqukumbela, imisonto yokuvimba amanzi iyinxalenye ebalulekileyo ekwakhiweni kweentambo kwiisicelo ezifuna ukukhuselwa ekungeneni kwamanzi. Ukusetyenziswa kwemisonto yokuvimba amanzi, eyenziwe ngezinto ezifana ne-EPE, i-PP, kunye ne-sodium polyacrylate, kunokubonelela ngomqobo osebenzayo ekuthinteleni umonakalo wamanzi, ukuqinisekisa ukuthembeka kunye nobude bexesha lentambo.
