Chemical Formula: |
Na2O·nSiO2 |
Uses: |
widely used as the adhesive for paper industry, casting, building materials, welding rods, as the adjuvant for soap-making and synthesizing cleaning agents, as the quick drying agent and water-proof agent in building trades. Besides, it is the basic raw material for making molecular sieve, silica gel, white carbon black, sodium metasilicate, etc. |
Specification: |
neutral (M: 3.1-3.4), alkali (M: 2.2-2.5), special (M: 2.6-2.8), there are liquid, solid, powdery *. It can also be made according to user's requirements. |
Packing: |
generally we do not provide packing for liquid product, or provide iron drum (55 gallon) or plastic drum.
Woven bag for solid product, 50kg. |
