| Property | Details |
|---|---|
| Solubility | - Highly soluble in water (exothermic reaction); solubility increases with temperature and decreases with modulus- Insoluble in organic solvents (ethanol, acetone, benzene) |
| Thermal Stability | - Stable at room temperature; decomposes at >1000°C to form Na?SiO? and SiO?- Liquid form: Freezes at 0–10°C (additives can prevent freezing) |
| Chemical Reactivity | - Strong alkaline: Reacts with acids to form silica gel (SiO?·xH?O)- Reacts with metal salts (Ca²?, Mg²?) to form insoluble silicates- Forms stable complexes with surfactants and polymers- Non-flammable, non-explosive |
| Hygroscopicity | Solid form is hygroscopic; absorbs moisture from air to form viscous liquid |
| Corrosivity | Corrosive to aluminum, zinc, and other amphoteric metals; non-corrosive to stainless steel, glass, and plastic |
Sodium Silicate (Water Glass) is a versatile inorganic chemical with wide industrial applications:
| Item | Requirements |
|---|---|
| Packaging | - Liquid form: 200 kg HDPE plastic drums, 1000 kg IBC tanks, or bulk tankers- Solid form: 25 kg woven bags with inner plastic liners, 500 kg bulk bags |
| Storage Conditions | - Store in cool, dry, well-ventilated area; avoid direct sunlight and extreme temperatures (5–35°C for liquid, <40°C for solid).- Keep sealed to prevent moisture absorption (solid) or evaporation (liquid).- Avoid contact with acids, metals, and oxidizing agents. |
| Shelf Life | - Liquid form: 6 months from production date (when stored properly)- Solid form: 12 months from production date |
| Handling Notes | - Use forklift with drum clamp for liquid drums; avoid dropping or collision.- Wear protective gloves, goggles, and apron during handling (due to alkaline corrosivity). |
| Hazard Classification | Details |
|---|---|
| Physical Hazards | None (non-flammable, non-explosive) |
| Health Hazards | - Skin Irritation (Category 2): May cause redness, itching, and burns upon prolonged contact.- Eye Irritation (Category 1): Causes severe eye irritation; may damage corneal tissue. |
| Environmental Hazards | Low toxicity to aquatic organisms; avoid discharge into water bodies. |
