Pakugwiritsa ntchito kubalalitsidwa kwa mpweya, pali zida ziwiri zofananira, zitsulo ndi nsalu, zida zachikhalidwe zazitsulo zimatulutsa mpweya kudzera m'magawo opaka zitsulo.Mpweya umalunjikitsidwa kumadera enaake zomwe zimapangitsa kusakanizika bwino kwa mpweya pamalo omwe anthu amakhalamo ndipo nthawi zambiri kumayambitsa kujambula ndi malo otentha kapena ozizira;pamene kuwala kwa nsalu kumakhala ndi mabowo yunifolomu pamodzi ndi dongosolo lonse lobalalitsidwa lautali, kupereka kufalikira kwa mpweya wofanana ndi yunifolomu m'malo omwe anthu akukhalamo, Kubalalika kwa mpweya wofanana kumatanthauza kusakaniza kwa mpweya wabwino komwe kumabweretsa ntchito yabwino kumadera omwe amafunika mpweya wabwino.
Zansalu zopangira mpweya wabwino
Kulemera kwapang'onopang'ono, kuyamwa kwaphokoso, zinthu zaukhondo, zosavuta kuzisamalira, zonsezi zathandizira kukwezeleza kachitidwe kakufalikira kwa mpweya m'zaka khumi zapitazi.Chotsatira chake, kufunikira kwa kuwala kwa mpweya wa nsalu kwawonjezeka, zomwe zinatsutsa kupanga bwino kwa fakitale yobalalitsa mpweya.Zolondola komanso zapamwamba kwambiri za kudula kwa laser kumatha kufewetsa njira zopangira nsalu.
Chifukwa Laser?
Nsalu yobalalitsira mpweya ndiyo njira yabwinoko yolowera mpweya wabwino pamene kuli kovuta kupanga mabowo osalekeza m'mbali mwa mayadi 30 autali kapenanso nsalu zotalikirapo ndipo muyenera kudula zidutswazo kupatula kupanga mabowowo.Ndi laser yokha yomwe ingazindikire izi.
Dongosolo la laser la CO2 likukhazikitsa miyezo yatsopano makamaka pomwe kudula kwenikweni komanso kutulutsa mwachangu kwa nsalu zaukadaulozi kumakhudzidwa.
