Overview This comparison outlines the technical performance differences between colloidal silica (nano-silica system) and traditional sodium silicate (water glass) as core materials for grouted fire glass, to support material selection decisions. 2. Core Technical Parameter Comparison 表格 Technical Indicator Colloidal Silica (Nano-Silica System) Traditional Sodium Silicate (Water Glass) Core Composition Amorphous nano-SiO₂ Sodium silicate (Na₂O·nSiO₂) SiO₂ Purity ≥99.8% ~70~75% (high sodium content) Na₂O Content ≤0.2% ~10~15% Appearance Colorless transparent liquid Light blue or colorless, easy to yellow Cured Layer Transmittance ≥88% 70~80%, easy to whiten Alkali Efflorescence Risk Extremely low (<1% defect rate) High (8~15% defect rate) Weather Resistance Excellent (20~25 year service life) Poor (3~5 year service life) Maximum Fire Rating 3.0h Class A insulation Usually ≤1.5h, unstable High-Temperature Fumes None, non-toxic Releases alkaline fumes 3. Performance Difference Analysis Optical Performance: Colloidal silica has refractive index close to glass substrate, with high transparency and no hazing. Sodium silicate easily causes surface whitening and reduced light transmittance due to sodium ion migration. Durability: Colloidal silica forms a dense three-dimensional silica network after curing, with good UV resistance and aging resistance. Sodium silicate system is prone to yellowing, cracking and peeling under long-term outdoor environment. Fire Resistance: Colloidal silica forms a stable ceramic layer at high temperature with reliable insulation performance. Sodium silicate has low softening point and poor high-temperature structural stability, making it difficult to achieve high fire resistance ratings stably. Environmental Safety: Colloidal silica is all-inorganic and non-toxic. Sodium silicate releases alkaline irritant fumes at high temperature, which is harmful to evacuation safety. 4. Comprehensive Cost Comparison Raw Material Cost: Sodium silicate has lower unit price, but colloidal silica has lower comprehensive cost due to much lower rework rate and longer service life Production Cost: Colloidal silica reduces rework, cleaning and maintenance processes, improving overall production efficiency by over 10% Life Cycle Cost: 5-year total cost of colloidal silica system is 10%~20% lower than water glass system; 10-year cost advantage is more significant 5. Application Recommendations For low-end temporary buildings with short service life: Sodium silicate can be considered for cost sensitivity For commercial buildings, public buildings and exterior curtain walls: Colloidal silica is recommended for reliable performance, low after-sales risk and product grade improvement For projects pursuing green building certification and high fire safety: Colloidal silica is the preferred technical solution Address: Huaiyin District, Jinan City, Shandong Province, China
