Kutsekereza madzi ndi chinthu chofunikira kwambiri pa ntchito zambiri za chingwe, makamaka zomwe zimagwiritsidwa ntchito m'malo ovuta. Cholinga cha kutsekereza madzi ndikuletsa madzi kulowa mu chingwe ndikuwononga ma conductor amagetsi omwe ali mkati. Njira imodzi yothandiza kwambiri yotsekereza madzi ndikugwiritsa ntchito ulusi wotsekereza madzi popanga chingwe.
Ulusi wotchinga madzi nthawi zambiri umapangidwa ndi chinthu chofewa chomwe chimatupa chikakhudzana ndi madzi. Kutupa kumeneku kumapangitsa kuti madzi asalowe mu chingwe. Zipangizo zomwe zimagwiritsidwa ntchito kwambiri ndi polyethylene yowonjezereka (EPE), polypropylene (PP), ndi sodium polyacrylate (SPA).
EPE ndi polyethylene yolemera mamolekyulu ambiri yomwe imayamwa madzi bwino kwambiri. Ulusi wa EPE ukakhudzana ndi madzi, umayamwa madziwo ndikukula, zomwe zimapangitsa kuti madzi asalowe mozungulira ma conductor. Izi zimapangitsa EPE kukhala chinthu chabwino kwambiri chogwiritsira ntchito ulusi wotseka madzi, chifukwa imapereka chitetezo chambiri ku kulowa kwa madzi.
PP ndi chinthu china chomwe chimagwiritsidwa ntchito nthawi zambiri. Ulusi wa PP ndi woopsa kwambiri pamadzi, zomwe zikutanthauza kuti umathamangitsa madzi. Ulusi wa PP ukagwiritsidwa ntchito mu chingwe, umapanga chotchinga chomwe chimaletsa madzi kulowa mu chingwe. Ulusi wa PP nthawi zambiri umagwiritsidwa ntchito limodzi ndi ulusi wa EPE kuti upereke chitetezo chowonjezera ku kulowa kwa madzi.
Sodium polyacrylate ndi polima wokhuthala kwambiri womwe nthawi zambiri umagwiritsidwa ntchito. Ulusi wa sodium polyacrylate uli ndi mphamvu zambiri zoyamwa madzi, zomwe zimapangitsa kuti zikhale chotchinga chothandiza kuti madzi asalowe. Ulusiwu umayamwa madzi ndikukula, zomwe zimapangitsa kuti madzi asalowe mozungulira ma conductor.
Ulusi wotchinga madzi nthawi zambiri umayikidwa mu chingwe panthawi yopanga. Nthawi zambiri umawonjezedwa ngati wosanjikiza wozungulira ma conductor amagetsi, pamodzi ndi zinthu zina monga kutchinjiriza ndi jekete. Zogulitsazo zimayikidwa m'malo oyenera mkati mwa chingwe, monga kumapeto kwa chingwe kapena m'malo omwe madzi amatha kulowa, kuti apereke chitetezo chokwanira ku kuwonongeka kwa madzi.
Pomaliza, ulusi wotchingira madzi ndi gawo lofunikira kwambiri popanga chingwe pa ntchito zomwe zimafuna chitetezo ku kulowa kwa madzi. Kugwiritsa ntchito ulusi wotchingira madzi, wopangidwa kuchokera ku zipangizo monga EPE, PP, ndi sodium polyacrylate, kungapereke chotchinga chothandiza ku kuwonongeka kwa madzi, ndikutsimikizira kudalirika ndi kukhalitsa kwa chingwecho.
