4. Kusinthasintha kwamphamvu: kuponyedwa kwa mchenga ndikoyenera kuponyera zitsulo zosiyanasiyana ndi aloyi, kuphatikizapo chitsulo, chitsulo, aluminiyamu, mkuwa ndi zina zotero.Mitundu yosiyanasiyana ya mchenga imatha kusankhidwa malinga ndi zofunikira za kuponyera kuti mupeze zotsatira zabwino zoponyera.
Mfundo zotsatirazi ziyenera kudziwidwa poponya nkhungu mchenga:
1. Ubwino wa mchenga: mchenga uyenera kukhala ndi mphamvu inayake ndi kukana kutentha, ukhoza kupirira mphamvu ya zitsulo zamadzimadzi ndi kutentha.Pamwamba pa nkhungu yamchenga iyenera kukhala yosalala, yopanda ming'alu ndi zolakwika kuti zitsimikizire ubwino wa kuponyera.
2. Kuthira kutentha: Ndikofunikira kwambiri kuwongolera kutentha kwazitsulo zamadzimadzi.Kutentha kwambiri kumayambitsa kuwotcha mchenga, kupindika kapena kusweka;Kutentha kochepa kwambiri kungayambitse kudzaza kosakwanira ndi kuponya mavuto abwino.
3. Kuthamanga kwachangu kumatha: Liwiro lololera loponyera ndi mode lingalepheretse kuchitika kwa zolakwika monga pores ndi mabowo amchenga.Kuthamanga kopitilira muyeso kwakanthawi kochepa kuyenera kutsatiridwa kuti nkhungu yamchenga ipitirire popanda kuyambitsa mpweya.
