About SODIUM METASILICATE PENTAHYDRATE

Physicochemical characteristics: White particles; Relative density: 0.8-1.0; Melting point: 70-73C; soluble in water or in thin alkali, insoluble in alcohol or in acid. The solution is alkaline, which presents detergency, emulsibility, dispersity, wettability, permeability and the buffer ability to the PH value, very hygroscopic and deliquescet when exposed to the air. Strong solution has a corroding effect on textile and skin.

Main usage: Detergent auxiliary, Metal surface treatment chemicals, grinding aids for ceramic, Raw material for fire-proof auxiliary, plastic maintenance agent, degreasing and textile printing and dyeing functional auxiliaries, water retention auxiliary, deinking auxiliary, peroxidase bleach stabilizer.
