(1)Chitsulo chosapanga dzimbiriKhalani ndi zovuta zochepa komanso zolimbitsa thupi zabwino, monga chitsulo chochepa cha kaboni ndi aluminiyamu. Ili ndi kuuma kotsika komanso kulimba mtima. Zimakhala zovuta kudula tchipisi komanso kosavuta kupanga tchipisi mukamadula, chomwe chimakhudza mtundu wa nkhope. Chifukwa chake, kukonza chitsulo chosaphika nthawi zambiri kumagwiritsa ntchito ngodya yayikulu, kudula kwakukulu kapena kupindika kwakukulu, kudula kochepa ndikudula madzi odula. Kanema wa Treaker ukhoza kukhala pansi pachidacho ndikupukuta kwamphesa ndikudula pamwamba kumatha kusintha. Kuphatikiza apo, miyala ya kaboni yotsika imayimitsidwa kuti ikhale yoyenga, ndipo ma alminiyam overlos amagwiritsidwa ntchito kuwonjezera kuuma kwazinthuzo ndikusintha makinawo mozizira.

Amakhala ndi mphamvu zambiri, kugwiritsa ntchito mphamvu kwambiri, komanso zida zodulira zimakonda kuvala. Chifukwa chake, mtundu wamtunduwu umakonzedwa pogwiritsa ntchito yg, yt ndi yw ma carbide ovala ndi kuvala kocheperako, kutsika kwakukulu ndi kusungunuka kwakukulu. Kuphatikiza apo, imvi imatayitsa chitsulo ndi "yoyera" imatha kusiya kuyamwa kwambiri. Kuyaka ndi chithandizo cha zovuta zolimba kumapangitsa chitsulo cholimba, kaboni kachitsulo ndi chitsulo cha kaboni ndi chitsulo cha kaboni ndi chitsimikiziro cha kaboni ndi chitsimikiziro cha kaboni
