Waa maxay daaweynta dusha Black Oxide?
Black oxide, oo ah hab caadi ah oo lagu daweeyo dusha kiimikaad. Okssaydhka madow waa habka caadiga ah ee daaweynta dusha kiimikada. Mabda'a ayaa ah in la soo saaro filim oksaydh ah oo ku yaal dusha birta si loo go'doomiyo hawada loona gaaro ujeedada ka hortagga miridhku. Marka shuruudaha muuqaalka aan sare loo qaadin, madow ayaa la isticmaali karaa, dusha sare ee qaybaha birta waa madow, taas oo sidoo kale loo yaqaan buluug.
Hababka sida caadiga ah loo isticmaalo daawaynta oksaydhka madow waxa ka mid ah kulayl dhaqameedka alkaline oo madow iyo madoobaad heerkulka qolka kaas oo dhaca hadhow. Si kastaba ha ahaatee, habka madow ee heerkulka qolka maaha mid aad waxtar u leh birta kaarboonka ee hooseeya. Madoobaadinta alkaline waa la kala qaybsan yahay, waxaana jira farqi u dhexeeya mar madow iyo laba jeer oo madow. Qaybaha ugu muhiimsan ee dareeraha madow waa sodium hydroxide iyo sodium nitrite. Farqiga heerkulka looga baahan yahay madow ma ahan mid weyn, oogada wanaagsan waxaa laga heli karaa inta u dhaxaysa 135-155 °C, laakiin waqtiga loo baahan yahay waa wax yar dheer.
