High-quality sodium nitrite brings stronger guards to the industrial field

Speaking of "sodium nitrite"

I believe everyone has heard of it for a long time

As a kind of industrial salt

Its appearance is similar to table salt

With good rust prevention effect on ferrous metals

Deeply rooted in the field of metal working fluids

It is favored by many people

 

Today, let's get to know sodium nitrite in depth.

 

Sodium nitrite is an inorganic salt produced by the combination of nitrite ions and sodium ions. Sodium nitrite is easily deliquescent, 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 flavor and is sometimes used to make fake table salt. Sodium nitrite reacts with oxygen to form sodium nitrate when exposed to air.

 

Sodium nitrite has many interesting properties and uses and is widely used in industry!

 

Important oxidizing agent

 

Industrial Na nitrite is an important oxidizing agent that reacts with many substances to induce the transfer of oxygen, e.g. in the preparation of dyes and pigments, and in the synthesis of certain organic compounds.

 

Metal surface treatment

 

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

 

In the treatment of metal surface, it is worth mentioning that the blackening treatment of metal, which is a kind of surface anticorrosive treatment, also called bluing treatment, in which the commonly used strong oxidizing agent needs to use sodium nitrite; in addition, in the production of alkaline degreasing agent, sodium nitrite will be added to the alkaline degreasing agent has two functions: to reduce alkalinity, and to have rust prevention effect on the iron and steel parts.

 

Water treatment

 

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

 

Construction field

 

In addition, Sodium Nitrite is often used as a concrete admixture in the construction industry to promote concrete solidification, improve its strength, and prevent concrete from freezing during construction at low temperatures in winter.

 

Others

 

In addition, it can also be used as bleaching agent for silk and linen, heat treatment agent for metal, corrosion inhibitor for steel, antidote for cyanide poisoning, laboratory analytical reagent, and has applications in bleaching, electroplating and metal treatment.

 

Industrial sodium nitrite plays an important role in the industrial field, its own characteristics make it suitable for a number of industrial processes, from dye preparation to metal protection, quietly contributing to all walks of life, let's cherish the value of these chemicals and ensure that the use of safety and environmental protection principles.
