Ng’anjo yamagetsi yopuma njerwa

Njerwa yotulutsa mpweya ya ng’anjo yamagetsi ndi mtundu wamtundu wachitsulo chubu ndi njerwa ya carbon magnesia. Mpweya wa mpweya ndi mapaipi azitsulo osatentha (φ3 × 1 kapena φ4 × 1), ndipo chiwerengero cha mapaipi achitsulo ndi pakati pa 10 ndi 100 malingana ndi kukula kwa njerwa. Matrix amapangidwa ndi njerwa zapamwamba za magnesia carbon, zomwe zimagwirizanitsidwa ndi moyo wa ng’anjo pansi. Chifukwa cha kuchuluka kwa mipope yachitsulo, imakhala ndi chiwombankhanga chachikulu komanso kukhazikika kwa mpweya wokhazikika pansi pa ntchito yoyenera, yomwe imatha kukwaniritsa zofunikira za ng’anjo yamagetsi pamwamba ndi pansi.
