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.

Sodium nitrite is a chemical compound with various industrial and culinary applications. In the food industry, it is commonly used as a preservative and color fixative, particularly in processed meats like bacon, hot dogs, and ham, to inhibit bacterial growth and maintain product color. Beyond its role in food preservation, sodium nitrite is utilized in chemical processes, such as the production of dyes and pharmaceuticals, as well as in some cooling and heating systems to prevent corrosion. However, its use in food has raised concerns due to potential health risks associated with the formation of nitrosamines, which are known carcinogens, when exposed to certain conditions. Consequently, regulatory limits and guidelines exist to ensure its safe use in food products.

Introduction Name:Sodium Nitrite Formula:NaNO2 CAS No:7632-00-0 UN No.:1500 Apperance:Crystal Assay:99% Application Industrial Grade NaNO2 Nitrite Salt is an oxidant corrosion inhibitor,suitable for low hardness or ultra-low hardness water treatment.This product is toxic, so it is mainly used in closed circulating cooling water system, is a dangerous corrosion inhibitor, when the use concentration is insufficient, not only no corrosion inhibition, but accelerate corrosion, the use concentration is usually 300 500mg/L. The optimal pH range of water quality is 8 10, so it is often used together with 300 600mg/L Na2CO3. Water quality pH< At 6, decomposition, no inhibition effect. Often mixed with sodium molybdate, on the one hand synergistic effect, on the other hand to reduce the dosage of both. Black gold only.It is antirust, ineffective to copper and other non-ferrous metals, and even corrosive.

Sodium nitrite serves a vital public health function: it blocks the growth of botulism-causing bacteria and prevents spoilage. Sodium nitrite also gives cured meats their characteristic color and flavor. 99% Cure Salt Crystal Sodium Nitrite NaNO2 is allowed to be used in our country hair color agent. regulations can be used for brittle livestock, canned poultry meat and meat products, the maximum use of 015g/kg. The residual amount in meat products shall not exceed 0.03g/kg (nitrite sodium meter), and the residual amount in salted ham is 0.07g/kg. Because it can form a strong carcinogen nitroso, the dosage should be strictly controlled.
