Products Description:

English name：Sodium metasilicate Pentahydrate
Formula：Na2SiO3·5H2O
Molecular weight：212.14
CASNO.：10213-79-3

Physicochemical characteristics：White particles; Relative density: 0.8-1.0; Melting point: 70-73℃; 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.

Product packing specification：Inner bag: PE plastic bag Outer bag: woven bag Net weight:25kg.

Storage and Delivery：Please store in a cool, dry and ventilated place. Keep products from being wet and avoid too much sun exposure during transportation. Temperature of products’ surroundings should be below 60℃.
