OverviewTechnical Data Inquiry


【Performance and Application】
Caustic soda is Colorless, transparent crystals, melting point:318.4℃, boiling point:1390℃, crispy. Pure solid caustic soda appear white, block, flake, bead, easily soluble in water, can release lots of heat. In water appear alkaline, feeling creamy, soluble in ethanol and glycerol, not soluble in acetone, ether. Strong corrosive, corrupt fiber, skin, glass, ceramic, etc.

It is used for making chemicals, the paper, soap and detergent, artificial silk and cellophane, make and oxidize aluminium, use for the silky luster of mercerized cotton fabrics of the fabrics and deal with bauxite of processing.

Can replace some soda ash and make glass. Process regenerated glue, acid waste water treatment and overcast ion exchange resin regeneration, etc.
