NaNO2 Sodium Nitrite Used As A Mordant In Fabric Dyeing 25 KG / BAG
Sodium nitrite is in the form of white to light yellow granules, rods or powder. It is hygroscopic.
Sodium nitrite is in the form of white to light yellow granules, rods or powder. It is hygroscopic.
Sodium nitrate is mainly used as a corrosion inhibitor and an inhibitor of metal embrittlement in boilers in the field of water treatment. When sodium nitrate is used as a metal embrittlement inhibitor, it needs to be compounded with sodium hydroxide and maintained in a certain proportion. Adding sodium nitrate to the low-pressure boiler system can prevent the embrittlement of metal materials. Besides, its applications in other fields are also very extensive.
Sodium nitrate can help prevent food spoilage and ensure safe consumption for humans. Large doses can be used in insecticides and rodenticides. In addition, sodium nitrate has many industrial applications, including in the fertilizer, photochemical and metal casting industries, etc.
Sodium nitrate is also a salt used in the production of fertilizers, explosives and rocket propellants. The uses of sodium nitrate also include being used as a preservative to preserve meat products.
