H.S. Code: 28151100

EC#215-185-5

Molecular Formula: NaOH

 

Characterisics:

White solid pearls or flakes with strong corrosiveness, easily soluble in water, presenting alkaline solution and heat liberation,presenting deliquescence when exposed to air.

 

Useage: 

Basic and important chemical feed, used as textiles industry,printing,detergent, paper-making, soap-making, metallurgy, glassenamel, medicament, oil-refining and making synthetic fiber, plastics, and many kinds of organic-mediacy, etc. 

 

Producing method:

Causssticizing Process

Natural soda is firstly dissolved into solution, then reacted with CaO. The slurry is filtrated in Plate-and-Frame Module and cleared. The clean solutioncanbe evaporation to get the finished product. 

 

Packing:

25kgs plastic woven bags lined with polythene bags,inside with plastic coating bags. 

caustic soda is mainly used as a raw material in the manufacturing of soaps, detergents, textiles and paper. Also, in water softening and treatment, drilling mud in oil field, refining petroleum products, in sanitation as hygiene products. In food and drug industry, it is used as acidity regulator, alkali and impregnants pigment
