Introduction Name:Sodium Nitrite CAS No: 7632-00-0 UN No: 1500 Formula: NaNO2 Assay:99% Application NaNO2 Sodium Nitrite reacts with oxygen, causing chemical changes on the metal surface and playing the role of passivation. It is often used in neutral corrosive medium, can effectively prevent or slow down the speed of metal corrosion. Used in electroplating industry as inorganic corrosion inhibitor. Sodium nitrite can be used for silk and flax bleaching, steel rust prevention, metal heat treatment and so on. It can also be used in the food industry as a preservative and colorant. Method NaNO2 Sodium Nitrite can be used in different kinds of metal coating post treatment. Metallic silver: in order to prevent the discoloration of silver coating, sodium nitrite and other corrosion inhibitors will be used in the process of treatment. Metal copper: copper plated metal is very common, in order to protect the copper plated metal, prevent copper oxidation discoloration, will be used containing sodium nitrite discoloration agent after the coating treatment to prevent discoloration. Storage NaNO2 Sodium Nitrite should be placed in low-temperature, dry and ventilated warehouse with tight doors and windows to prevent direct sunlight.It can be stored with other nitrates except ammonium nitrate in stock, but stored separately from organic and flammable reducing agents, and isolated from fire sources.
