Yiziphi izizathu zenhliziyo emnyama ye izitini ezikhanyisayo?

Inhliziyo emnyama yinto eyenzeka kalula ekukhiqizeni izitini eziphikisayo. Izici zalolu hlobo lwesitini yilezi: umbala ongaphezulu wesitini uyashintsha kancane kancane, usuka ophuzi-oluhlaza phezulu uye ompunga-omnyama ngaphakathi. Uma lolu hlobo lwesitini esiwumgogodla omnyama lubalwa kabusha endaweni ene-oxidizing, ingxenye ewumgogodla omnyama ingashiswa kabusha ibe mhlophe.

Ama-oxide ayinhloko wokungcola ezitini i-iron oxide ne-titanium oxide. Kungacatshangwa ukuthi isitini esimnyama siba mhlophe ngemva kokudubula kabusha endaweni ene-oxidizing, kungase kuthiwe umoya wokudubula kanye nama-oxide angcolile ensimbi ne-titanium yizimo zokukhiqizwa kwama-black cores. Kodwa-ke, lapho i-iron ne-titanium oxides kuhlangana noma ekhona ewodwa, anemiphumela ehlukile ekubaleni imibala kwezitini eziphikisayo. Uma i-titanium ion ikhona iyodwa, umbala awubalulekile, futhi umzimba wezitini uba luhlaza okwesibhakabhaka kancane, kanti uma i-iyoni yensimbi ikhona iyodwa, umzimba wezitini unombala osawolintshi.

Okungenhla kuyisizathu sokuthi izitini eziphikisayo zikhiqiza ama-black cores. Ngaphezu kwalokho, ngisho nasendaweni ene-oxidizing, umbala kanye nokucwiliswa kwe-alumina nakho kungandisa ama-cores amnyama. Ngesikhathi sokukhiqiza, kuyadingeka ukulawula ukulungiswa kwezinto zokusetshenziswa, ukulawula ukushisa nokushisa, ukunciphisa amathuba okuba nezinkinga zenhliziyo emnyama.
