Chifukwa chiyani amadzipereka kwambiri pakuumitsa zitsulo zowuma? Kusinthaku akuyembekezeka kuchepetsa kugwiritsa ntchito kwawo madzi 93% ndipo ichepetsa kufunika kwa mayiwe oyipitsa. Kuchepetsa kufunika kwa magwero am'madzi atsopano kudzathandizira kusiya kukonza zitsulo mtengo wake ndipo utha kukhala wothandiza chilengedwe. Madamu owononga madzi amatha kulephera, kufalitsa zinthu zapoizoni m'dera lapafupi ndi matebulo amadzi, zomwe sizingowononga chilengedwe, zimayambitsa kulengeza pazoipa komanso zovuta.
Izi ndi mfundo zomwe ST Equipment & Tekinoloje yakhala ikulalikira kwa zaka zambiri. Wodzilekanitsa wathu wamagetsi amagwiritsa ntchito njira youma kuti akwaniritse zabwino zonse zomwe zanenedwa pamwambapa. Kuphatikiza apo, mchitidwewo umatha kusiyanitsa miyala yazitsulo mpaka m'miyeso yaying'ono 10 microns, kulola makasitomala athu kuti azitenga mafuta ochulukirapo kuchokera kumigodi yawoyi pomwe akuchepetsa mitsinje yonse.
