Ki tretman sifas oksid nwa a?
Ksid nwa, yon mwayen komen nan tretman sifas chimik. Ksid nwa se yon metòd komen nan tretman sifas chimik. Prensip la se pwodwi yon fim oksid sou sifas metal la pou izole lè a epi reyalize objektif prevansyon rouye. Lè kondisyon aparans yo pa wo, yo ka itilize nwasi, epi sifas pati asye yo nwasi, yo rele tou ble.
Metòd yo souvan itilize nan tretman oksid nwa gen ladan nwasi tradisyonèl alkalin chofaj ak nwasi tanperati chanm ki rive pita. Sepandan, pwosesis nwasi a nan tanperati chanm pa trè efikas pou asye kabòn ki ba. Se nwasi alkalin sibdivize, epi gen yon diferans ant yon fwa nwasi ak de fwa nwasi. Konpozan prensipal yo nan likid nwasi yo se idroksid sodyòm ak nitrite sodyòm. Diferans tanperati ki nesesè pou nwasi se pa gwo, epi yo ka jwenn yon bon sifas ant 135-155 °C, men tan ki nesesè yo se yon ti kras long.
