Machubu apakati ndi amakona anayi opangidwa kuchokera ku chitsulo chofewa Q235 amagwiritsidwa ntchito nthawi zambiri pomanga, zomangira zothandizira, ndi zomangamanga. Machubuwa amadziwika ndi kukhazikika kwawo, kuphweka kwawo kupanga, komanso kuyenererana ndi njira zosiyanasiyana zowotcherera ndi kupanga. Matchulidwe a Q235 akuwonetsa kuti chitsulocho chimapangidwa ndi chitsulo chochepa cha carbon.
