NaNO2 Sodium Nitrite Used as Metal Heat Treatment Agent 25 KG / BAG
Sodium nitrite is an industrial salt that is not edible, although similar to the table salt, sodium chloride. Sodium nitrite is widely used in cured meat, and if methemoglobin cyanosis occurs, methemoglobin can be reduced by methylene blue. Sodium nitrite has a salty taste and is used to make fake salt. Sodium nitrite reacts with oxygen to form sodium nitrate when exposed to air. If heated above 320 ° C, it decomposes to produce oxygen, nitrogen oxide and sodium oxide. Contact with organic matter is easy to burn and can explode.

1. In metal surface treatment, sodium nitrite is used as a high-temperature oxidizer for metal surface treatment, passivation technology, rust prevention and metal surface treatment technology.
2. In the printing and dyeing industry, sodium nitrite is used as a diazo dye to bleach fabrics, and sodium nitrite is also used as a preservative in food and medicine. Sodium nitrite is used in the bleaching process of fabrics to print a clearer pattern on the fabric, making the fabric more durable and whiter.
3. NaNO2 is used to preserve food. When used properly, sodium nitrite is considered a food safety chemical. The recommended dose of NaNO2 as an additive and preservative for meat and fish is strictly controlled under 0.6%, as higher concentrations can cause poisoning in humans.
4. In rubber production and processing, sodium nitrite increases the dimness of rubber raw materials during processing and removes impurities in the latex. Used in the production of plastics, ink, film and so on.
5. Recently, sodium nitrite is an effective way to increase blood flow by dilating blood vessels, acting as a vasodilator. A mixed intravenous drip containing sodium nitrite solution for emergency cyanide poisoning.
6. In the water treatment industry, sodium nitrite provides nitrates for aerobic microorganisms to help speed up wastewater treatment.
