ಸಿಲಿಕಾ ಸೋಲ್ (ಕೊಲೊಯ್ಡಲ್ ಸಿಲಿಕಾ) ಮತ್ತು ಸಿಲಿಕಾ ಸ್ಲರಿ (ಸಿಲಿಕಾ ಜಲೀಯ ಪ್ರಸರಣ) ಎರಡೂ ಸಿಲಿಕಾ ಪುಡಿಯಿಂದ ತಯಾರಿಸಿದ ಉತ್ಪನ್ನಗಳಾಗಿವೆ. ಆದಾಗ್ಯೂ, ಅವುಗಳ ಸಂಸ್ಕರಣಾ ತಂತ್ರಜ್ಞಾನ ಮತ್ತು ಅಪ್ಲಿಕೇಶನ್ ಉದ್ದೇಶಗಳ ಕಾರಣದಿಂದಾಗಿ ಅವು ಭಿನ್ನವಾಗಿರುತ್ತವೆ. ಕೆಳಗೆ ನಾವು ವಿಭಿನ್ನ ಆಯಾಮಗಳಿಂದ ಎರಡರ ನಡುವಿನ ವ್ಯತ್ಯಾಸವನ್ನು ವಿಶ್ಲೇಷಿಸುತ್ತೇವೆ.
1. Definition Differences
| ಕಲೆ | Silica Sol (ಕೊಲಾಯ್ಡಲ್ ಸಿಲಿಕಾ) | Silica Slurry (ಸಿಲಿಕಾ ಜಲೀಯ ಪ್ರಸರಣ) |
|---|---|---|
| Core Definition | A stable dispersion system of nano-sized silica particles uniformly distributed in water, usually with electrostatic stabilization. | Suspension of fine silica powder dispersed in water, forming a slurry. |
| ಕಣದ ಗಾತ್ರ | 5–100 nm (commonly 10–30 nm) | 0.5–5 μm (typically D90 ≈ 3 μm) |
| ಗೋಚರತೆ | Transparent or slightly opalescent liquid, stable dispersion. | Milky white suspension, easily stratified, requires uniform stirring. |
| Stabilization Method | Electrostatic repulsion via OH⁻ ions or steric hindrance (physical stabilization). | Mechanical agitation + dispersant/stabilizer to prevent sedimentation and agglomeration. |
| Typical Solid Content | 20–50% | 30–50% |
| Quick Memory Tip | Silica Sol → Nano particles + Transparent aqueous solution | Silica Slurry → Micro particles + Milky white suspension |
2. Application Differences
| ಕೈಗಾರಿಕೆ | Silica Sol Applications | Silica Slurry Applications |
|---|---|---|
| Textiles | Anti-shrinkage finishing, flame-retardant finishing, water-repellent finishing | Fabric coating, surface finishing, enhancing firmness, wear resistance, anti-slip |
| Catalysts | As a binder for catalyst carriers (main use) | None |
| ಲೇಪನಗಳು | Acid-resistant coatings, corrosion-resistant coatings | Functional filler, thickening agent |
| Casting | Precision casting binder, coating binder | Investment casting slurry, functional filler |
| Electronics | CMP polishing slurry | Rarely used |
| Others | Catalysts, heat-resistant materials | Building materials, rubber composites, textile auxiliaries |
3. ಗೋಚರತೆ & Transportation Differences
| Feature | Silica Sol | Silica Slurry |
|---|---|---|
| ಗೋಚರತೆ | Colorless transparent liquid (like pure water) | Milky white suspension or slurry |
| Transportation Stability | Highly stable, long-term non-stratification | Easily stratified, requires stirring before use |
| Sensitivity to External Environment | Sensitive to pH changes, requires stability control | Sensitive to temperature, vibration, and prone to settling |
