CRITICAL WARNINGS
1. Particle Size Selection: Select the appropriate particle size based on application. Coarse powder (30-50 μm) for concrete, fine powder (1-10 μm) for epoxy and paints.
2. Silicosis Risk: Prolonged dust exposure (especially with crystalline silica-containing glass powders) may cause silicosis. Use respiratory protection in dust-generating operations.
3. Water Contact: Insoluble in water but may react in alkaline environments.
4. Hydrofluoric Acid: Glass powder dissolves in hydrofluoric acid. Special precautions required when working with this acid.
5. Storage: Store in a dry environment. Moisture may affect product flowability and performance.
6. Mixing: Adequate mixing time is required to ensure homogeneous distribution of powder.
7. Recycling: Produced from recycled waste glass, environmentally friendly material.
8. Versatile Application: Wide range of applications from concrete to plastics, epoxy to ceramics, insulation to abrasives.
9. Cost Effective: More economical than natural filler materials.
10. Certification: Certification may be required for food, pharmaceutical, or specialty applications.
