Industrial fields for sodium nitrite applications

Industrial fields for sodium nitrite applications

Industrial grade sodium nitrite has a wide range of applications in various fields, such as the construction industry, printing and dyeing industry, cleaning industry, etc. have the shadow of sodium nitrite. As an inorganic salt generated by nitrite ions and sodium ions, it belongs to oxidants It is also a reducing agent. In the rapid reaction, the importance of sodium nitrite is also reflected. Common applications are as follows:

1. Antifreeze: Chlorine-free antifreeze, with excellent antifreeze effect, mainly used for commercial concrete, can be adapted to the winter construction requirements of -5 ~ -20, can greatly reduce the alkali content, and can avoid concrete Reaction, so that the antifreeze itself does not precipitate or crystallize when stored at negative temperature.

2. Corrosion inhibitor: Adding in the production of steel can slow down the corrosion of steel, such as steel rust prevention and isolation and rust removal, and can also be used as a rust inhibitor for cutting oil, lubricating oil, antifreeze fluid and hydraulic system.

3. Heat treatment agent: Strengthen the adhesion between the metal surface and the coating to ensure that the electroplating effect of the metal parts meets the standards.

4. Bleaching agent: It can bleach silk, linen and other textiles. It has strong bleaching power, good sterilization and deodorization effect, and reduces dye pollution.

5. Preservatives: It is more commonly used as a preservative for water-soluble adhesives and adhesive emulsions. It can also be added to the prescribed food production to extend the shelf life of the food, but in view of the toxic use, there are order restrictions.

6. Antidote: It has a good detoxification effect on cyanide poisoning and plays an important role in the pharmaceutical industry.

7. Mordant: Mordant for fabric dyeing, which can effectively improve the printing and dyeing quality of textiles.

8. Terminator: It can be used as a terminator for the copolymerization of butadiene and styrene emulsion, used to make nitro compounds, caprolactam, p-aminophenol, vulcanization accelerator and other raw materials;

These are the common applications of sodium nitrite in the industrial field. We will not introduce other applications one by one. I hope that the above content will be helpful to you that you are understanding! A comprehensive understanding of sodium nitrite products can only be used Give full play.
