Njerwa yamatayala okwera kwambiri yopangira mbaula yotentha

Njerwa yokhayokha ya aluminiyumu yopangira mbaula yotentha ndi mtundu wa thupi losungira kutentha lomwe lili ndi mawonekedwe abwino kwambiri otentha monga mphamvu yosinthira kutentha, malo osungira kutentha, mpweya wabwino, komanso kukana pang’ono, komwe kumadziwika kwambiri ndikuvomerezeka ndi makampani opanga chitsulo. Njerwa za tcheki ndi mtundu wa sing’anga wosinthira kutentha, womwe umagwiritsidwa ntchito kumtunda chapamwamba komanso kumtunda kwa chosinthira chophikira chotentha kuti usunge kutentha. Pakutenthetsa mpweya wozizira mumlengalenga, umagwira ntchito yofunikira kwambiri.

Njerwa zapamwamba za alumina zama mbaula otentha zimapangidwa ndi aluminiyamu yayikulu yolumikizira ndi dongo. Pakati pawo, malinga ndi magawo osiyanasiyana ogwiritsira ntchito, njerwa zingapo zamitundu yosiyanasiyana zomwe zili ndi Al2O3 zopitilira 48% zimaperekedwa kuti zizigwiritsa ntchito bwino ntchito yomanga chitofu, komanso kukhazikika ndi moyo wautali wokonzanso pambuyo pake gwiritsani.

Zinthu zitatu zomwe zimaimira njerwa zapamwamba za masitovu otentha

Njerwa zodziwika bwino za njerwa za mbaula yotentha: zidagawika m’makalasi atatu: RL-65, RL-55, RI-48;

Njerwa zotsika kwambiri za masitovu otentha: ogawika m’magulu asanu ndi awiri: DRL-155, DRL-150, DRL-145, DRL-140, DR-1 35, DRL-130, ndi DRL-127.

Njerwa zotsekemera zopangira ma aluminiyumu obwezeretsanso masitovu otentha: Malinga ndi zotayidwa, imagawidwa m’magulu atatu: RL-65, RL-55, ndi RI-48; itha kusinthidwa kuti ipange mabowo 7, dzenje 19, mabowo 37 ndi mitundu ina ya njerwa.
