Ithini i-hydrogen yensimbi encibilikisiwe ngesithando somlilo esincibilikayo?

Ensimbini empunga, i-hydrogen iyisici esiyingozi, ukuncipha kokuqukethwe, kuba ngcono. Ngenxa yokuqukethwe okuphezulu kwekhabhoni ne-silicon ku-iron cast, ukuncibilika kwe-hydrogen kuzo kuphansi. Ensimbini encibilikisiwe ku-cupola, okuqukethwe kwe-hydrogen kuvamise ukuba ngu-0.0002~0.0004%. Ensimbi encibilikisiwe encibilikisiwe yisithando somlilo sokungeniswa, ngenxa yokuthi ukuxhumana phakathi kwensimbi negesi yesithando somlilo kuncane, okuqukethwe kwe-hydrogen ngokuvamile kuphansi, cishe ngo-0.0002%. I-hydrogen ekhiqizwa ukulingisa mancane amathuba okuthi ibangele ukubola kanye nezimbobo ekubunjweni.
