Ubufakazi bokuqhuma kwe-Shenhai
Uthuli lwe-aluminium, ekwazi ukuqhuma, ihlukaniswa njengezinto ezivuthayo zeClass II. Ihlangana namanzi ukukhiqiza igesi ye-hydrogen nokushisa.
Uma kwenzeka kuqhuma uthuli lwe-aluminium, ukusebenzisa amanzi ukucima akukhuthazwa. Izicisha-mlilo ezinegwebu ziyinketho enconyiwe (ikakhulukazi ekucubunguleni iphrofayili ye-aluminium) njengoba igwebu lihlukanisa amalangabi emoyeni. Lokhu kungenxa yokusabela kwamakhemikhali e-aluminium ngamanzi, elikhiqizayo i-hydrogen igesi, ukwenza amanzi angasebenzi ukucisha umlilo. Kube nesigameko lapho ukuqhuma okudalwe khona ukuzama ukucisha uthuli oluvuthayo lwe-aluminium ngamanzi..
