Mention "sodium nitrite"

I'm sure you've all heard of him

As an industrial salt

Its appearance is similar to table salt

With good rust protection against ferrous metals

Deeply rooted in the field of metal working fluids

Get a lot of people's favor

Today, let's take a deeper look at sodium nitrite

Sodium nitrite is an inorganic salt produced by the combination of nitrite ion and sodium ion. Sodium nitrite is easily deliquescent, easily soluble in water and liquid ammonia, its aqueous solution is alkaline, slightly soluble in ethanol, methanol, ether and other organic solvents. Sodium nitrite has a salty taste and is sometimes used to make fake salt. Sodium nitrite reacts with oxygen to form sodium nitrate when exposed to air.

Sodium nitrite has many interesting properties and uses,

Widely used in industry!

Important oxidant

Industrial sodium nitrite is an important oxidizing agent that can react with many substances to promote the transfer of oxygen, for example: in the preparation of dyes and pigments, and the synthesis of certain organic compounds.

Metal surface treatment

Widely used in metal surface treatment and protection; It can be used as one of the components of metal corrosion inhibitors, forming a protective oxide film to prevent the metal from further oxidation and damage, making the metal more durable and extending its service life.

■ In the treatment of the metal surface, it is worth mentioning that the blackening of the metal, which is a surface anti-corrosion treatment, also known as blue treatment, which commonly used strong oxidants need to use sodium nitrite; In addition, in the production of alkaline degreasing agent, adding sodium nitrite to alkaline degreasing agent has two functions: reducing alkalinity and having anti-rust effect on steel parts.

Water treatment

It is understood that in the water treatment process, industrial sodium nitrite can also react with chloride to reduce or remove the residual chlorine in the water, thereby improving the water quality to better protect the water environment.

Architectural field

In addition, sodium nitrite is often used as a concrete admixture in the construction industry to promote the solidification of concrete, improve its strength, and prevent the freezing of concrete during low-temperature construction in winter.

other

Industrial sodium nitrite plays an important role in the industrial sector, its own characteristics make it suitable for multiple industrial processes, from dye preparation to metal protection, silently contributing to a wide range of industries, let us cherish the value of these chemicals, and ensure that the principles of safety and environmental protection are followed when using.
