What is Caustic Soda?

Caustic soda – or sodium hydroxide – is natural co-product of chlorine production. In addition, indeed  laws of chemistry define that for every tonne of chlorine you produce, about 1100 kg of caustic soda is also produced, together with 28 kg of hydrogen.
In addition, it`s basic reactant in making wide range of organic chemicals. 32 % of caustic production uses in this way.

Caustic Soda
Paper, pulp and cellulose industries also are major users of caustic soda. Inorganic chemicals like paints, glass, ceramics uses in fuel cell production. Furthermore, cosmetics are also very important.

NaOh also uses on: food industry, water treatment (flocculation of heavy metals and acidity control), soaps and detergents sectors, textile sector (bleaching agent), mineral oils (preparation of greases and fuel additives). Furthermore, it uses as synthesis of synthetic fiber rayon. 4% of caustic soda also used in refining aluminium from its ore bauxite.

Furthermore, it has miscellaneous applications, like the synthesis of pharmaceutical compounds, rubber recycling and the neutralization of acids.

Description:

Caustic soda has many uses at industrial level. It used in cleaning agents manufacturers such as soaps and toilet cleaners.
Sodium Hydroxide also uses in paint stripping. When there is a need to remove paint on any surface including wood, metal, or any furniture caustic soda can come in handy when removing the old paint. When applied to the surface, it causes the paint on the surface to detach itself. This process is known as paint stripping. Caustic soda clears the surfaces of any paint.
At home, it is used to unblock all drainage. A little quantity of caustic soda poured into blocked drainage pipes can clear the pipes of any blockages.

Most people use caustic soda on door stripping. When they wish to change the paint on doors, they use caustic soda to remove the old paint from the doors. Caustic soda easily strips off paint from doors. However, handling NaOH requires high levels of caution as it is a very corrosive chemical compound that is very hazardous to humans.
