Properties:
Melting point 1089℃, easily soluble in water and dilute lye, insoluble in alcohol and acid, the aqueous solution is alkaline.
Sodium Metasilicate is easy to absorb moisture and deliquescence when exposed to the air, and has the ability to descale, emulsify, disperse, wet, penetrate and buffer the pH value.
Application：
(1) Sodium Metasilicate Anhydrous/Pentahydrate is used for manufacturing detergent, fabric treatment agent and paper deinking agent, etc.
(2) Sodium Metasilicate Anhydrous/Pentahydrate also used for textile, electroplating, filler and catalyst, etc.
