Chii chinonzi Black Oxide chepamusoro kurapwa?

Black oxide, nzira yakajairika yemakemikari pamusoro pekurapa.Black oxide inzira yakajairika yemakemikari pamusoro pekurapa.Nheyo yacho ndeyekugadzira firimu re oxide pane simbi pamusoro kuti iparadzanise mhepo uye kuzadzisa chinangwa chekudzivirira ngura.Kana izvo zvinodiwa zvekuonekwa zvisiri zvakakwirira, kusviba kunogona kushandiswa, uye pamusoro pezvikamu zvesimbi zvakasvibiswa, izvo zvinonziwo bhuruu.

Nzira dzinowanzo shandiswa dzeblack oxide kurapwa dzinosanganisira dzechinyakare alkaline kudziyisa kusviba uye kudzima tembiricha yemukamuri izvo zvinoitika gare gare.Nekudaro, iyo yekusviba maitiro pakudziya kwekamuri haina kunyatsoshanda kune yakaderera kabhoni simbi.Alkaline blackening yakakamurwa, uye pane musiyano pakati pekudzima kamwe uye kusviba kaviri.Zvikuru zvinoumba blackening liquid is sodium hydroxide uye sodium nitrite.Musiyano wetembiricha unodiwa pakusviba hausi wakakura, uye nzvimbo yakanaka inogona kuwanikwa pakati pe135-155 ° C, asi nguva inodiwa yakati rebei.
