SMA
Sodium Metasilicate Anhydrous
6834-92-0
122.1
Na2SiO3
229-912-9
2839110000
Appearance: white granular powder
Properties and functions:
SMA is strongly alkaline, having strong capacity of cleaning, buffering and softening, counteracting acidic contamination, emulsifying fat and oil, deflocculating to inorganic.
It can replace STPP to be used for the manufacture of effective detergents and rust remover for metal, reducing environmental pollution, preventing corrosion for metal (zinc, aluminum, etc.).
Main indexes:
| Index | Standard |
| Sodium oxide (Na2O) by wt % | 49.5~51.5 |
| SiO2 by wt % | 45.0~47.0 |
| Water insoluble % | 0.05 max |
| Fe by ppm | 100 max |
| Whiteness % | 90 min |
| Bulk Density by g/L | 980~1350 |
| Particle Size % (16-80mesh) | 93 min |
SMA is widely used for:
Detergents
Rust remover for metal
Grinding aids for ceramics
Deinking agent for paper
Dyeing and printing auxiliary for removing oil in textile industry
Raw material for flameproofing agent
Plastic maintenance agent
Water retention agent
Water reducing agents
There are 3 types of sodium metasilicate: Sodium Metasilicate Anhydrous/ Pentahydrate/ Nonahydrate Rawchem is running anhydrous and pentahydrate, not nonahydrate
We normally list 24 months as the shelf life in our COA, the real shelf life can be slightly longer than 24 months if it's stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials), but it's still suggested to avoid long time storage
