Chii "s iyo dema oxide pamusoro pekurapwa?

Dema oxide, nzira yakajairika yemakemikari kurapwa. Dema oxide inzira yakajairika yemakemikari ekumusoro kurapwa. Iyo nheyo ndeyekuburitsa iyo yefirimu yehusiku pane iyo simbi pamusoro yekuparadzanisa mhepo uye kuzadzisa chinangwa chekudzivirira kwekudzivirira. Kana chitarisiko chinodiwa chisiri chakakwirira, kusviba kunogona kushandiswa, uye pamusoro pezvikamu zvesimbi zvakasviba, izvo zvinonzi zvakare bhuruu.

Nzira dzinowanzoshandiswa dzeBlack Oxide kurapwa kunosanganisira tsika yechinyakare yekudzora bloage uye tembiricha tembiricha inoitika gare gare. Nekudaro, maitiro ekutsvaira ari pamhepo tembiricha haishandiswe kwazvo kune yakaderera carbon simbi. Alkaline Blackening yakakundwa, uye pane musiyano pakati pekuti kana kaviri uye kaviri kutakura. Izvo zvinhu zvikuru zvemvura yekubheka ndeye sodium hydroxide uye sodium nitrite. Musiyano wekupisa unodikanwa kuti usvike hahuwiri, uye nzvimbo yakanaka inogona kuwanikwa pakati pegumi nematanhatu c, asi iyo nguva inodikanwa idiki.
