Kutsekereza madzi ndi chinthu chofunikira kwambiri pazingwe zambiri, makamaka zomwe zimagwiritsidwa ntchito m'malo ovuta. Cholinga cha kutsekereza madzi ndikuletsa madzi kulowa mu chingwe ndikuwononga ma conductor amagetsi mkati. Imodzi mwa njira zothandiza kwambiri zopezera madzi kutsekereza ndi kugwiritsa ntchito madzi kutsekereza ulusi pomanga chingwe.
Ulusi wotsekereza madzi nthawi zambiri umapangidwa ndi zinthu za hydrophilic zomwe zimatupa zikakumana ndi madzi. Kutupa kumeneku kumapanga chotchinga chomwe chimalepheretsa madzi kulowa mu chingwe. Zomwe zimagwiritsidwa ntchito kwambiri ndi polyethylene (EPE), polypropylene (PP), ndi sodium polyacrylate (SPA).
EPE ndi polyethylene yotsika kwambiri, yolemera kwambiri ya molecular yomwe imakhala ndi madzi abwino kwambiri. Ulusi wa EPE ukakumana ndi madzi, umatenga madziwo ndikukula, ndikupanga chisindikizo chopanda madzi kuzungulira ma conductor. Izi zimapangitsa EPE kukhala chinthu chabwino kwambiri cha ulusi wotsekereza madzi, chifukwa imapereka chitetezo chokwanira kumadzi olowera.
PP ndi chinthu china chomwe chimagwiritsidwa ntchito nthawi zambiri. Ulusi wa PP ndi hydrophobic, zomwe zikutanthauza kuti amathamangitsa madzi. Akagwiritsidwa ntchito mu chingwe, ulusi wa PP umapanga chotchinga chomwe chimalepheretsa madzi kulowa mu chingwe. Ulusi wa PP nthawi zambiri umagwiritsidwa ntchito limodzi ndi ulusi wa EPE kuti upereke chitetezo chowonjezera pakulowa kwamadzi.
Sodium polyacrylate ndi polymer ya superabsorbent yomwe imagwiritsidwa ntchito nthawi zambiri. Ulusi wa sodium polyacrylate uli ndi mphamvu yayikulu yotengera madzi, zomwe zimawapangitsa kukhala chotchinga chothandiza polimbana ndi kulowa kwa madzi. Ulusiwu umatenga madzi ndikukulitsa, ndikupanga chisindikizo chopanda madzi kuzungulira ma conductor.
Ulusi wotsekereza madzi nthawi zambiri umaphatikizidwa mu chingwe panthawi yopanga. Amawonjezedwa ngati wosanjikiza mozungulira ma conductor amagetsi, pamodzi ndi zinthu zina monga kutsekereza ndi jekete. Zogulitsazo zimayikidwa m'malo oyenera mkati mwa chingwe, monga kumapeto kwa chingwe kapena m'madera omwe amatha kulowetsa madzi, kuti apereke chitetezo chokwanira ku kuwonongeka kwa madzi.
Pomaliza, ulusi wotsekereza madzi ndi gawo lofunikira pakumanga kwa chingwe pazogwiritsa ntchito zomwe zimafunikira chitetezo kuti madzi asalowe. Kugwiritsa ntchito ulusi wotchinga madzi, wopangidwa kuchokera ku zinthu monga EPE, PP, ndi sodium polyacrylate, angapereke chotchinga chogwira ntchito motsutsana ndi kuwonongeka kwa madzi, kuonetsetsa kudalirika ndi moyo wautali wa chingwe.
