Version 10: Technical Comparative Edition | Fumed SIlica / Nano SIlica vs. Sodium Silicate for Fire Glass
Manufacturer: ANDEHU NEW MATERIALS (SHANDONG) CO., LTD
1. Overview
This comparison outlines the technical performance differences between Fumed SIlica / Nano 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 Fumed SIlica / Nano 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: Fumed SIlica / Nano 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: Fumed SIlica / Nano 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: Fumed SIlica / Nano 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: Fumed SIlica / Nano 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 Fumed SIlica / Nano SIlica has lower comprehensive cost due to much lower rework rate and longer service life
Production Cost: Fumed SIlica / Nano SIlica reduces rework, cleaning and maintenance processes, improving overall production efficiency by over 10%
Life Cycle Cost: 5-year total cost of Fumed SIlica / Nano 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: Fumed SIlica / Nano SIlica is recommended for reliable performance, low after-sales risk and product grade improvement
For projects pursuing green building certification and high fire safety: Fumed SIlica / Nano SIlica is the preferred technical solution
