Study on Char Layer Structure of Nano-Silicon Fire Gel in Fire

Next-Gen Fumed Silica （Nano Silica） for Fire-Resistant Glass – Outperform Traditional Water Glass Manufacturer: ANDEHU NEW MATERIALS (SHANDONG) CO., LTD 1. Product Overview Tired of efflorescence, whitening and low transmittance that plague traditional sodium silicate fire glass? Andehu Fumed Silica （Nano Silica） delivers a step-change upgrade: a high-purity nano-silica dispersion that produces crystal-clear, long-lasting Class A insulating fire glass without the aging defects of old-school water glass formulas. Built on cutting-edge nano-silica technology, our product serves as the core interlayer material for grouted and laminated fire glass, bringing optical quality, weather resistance and fire performance to a new level. It is the preferred choice for high-end commercial buildings, curtain walls and projects that demand both safety and aesthetics. 2. Clear Advantages Over Traditional Water Glass 表格 Performance Traditional Sodium Silicate Andehu Fumed Silica （Nano Silica） Optical Clarity Low, often hazy, easily whitens ≥88% transmittance, crystal clear, no haze Efflorescence High sodium content, severe whitening over time Low sodium (≤0.3%), anti-efflorescence formula Yellowing Resistance Prone to yellowing under UV UV-stable, curtain wall grade loses ≤2% transmittance after 1000h QUV Fire Insulation Moderate, inconsistent structure Dense 3D silica network, uniform and reliable insulation Curing Shrinkage High shrinkage, easy to crack ≤3% shrinkage, low internal stress Service Life 5–10 years indoor only 15+ years indoor, 25+ years for curtain wall grade 3. Standout Product Features ✅ Museum-Level Clarity: Refractive index matched to glass. Your fire glass will look like ordinary architectural glass – clear, colorless, no milky appearance. ✅ No More Unsightly Whitening: Low-sodium formula inhibits alkali migration and efflorescence, keeping edges and surfaces clean for years. ✅ Genuine Class A Fire Rating: Three-stage fire reaction delivers both integrity and insulation, passing standard fire tests with consistent back-face temperature control. ✅ Built to Last Outdoors: Curtain wall grade withstands UV, rain, thermal cycling and coastal salt spray, engineered for decades of exterior service. ✅ Drops Into Your Existing Line: Compatible with standard pouring and lamination equipment – no expensive machine upgrades required. 4. How It Works in a Fire When heat hits, our Fumed Silica （Nano Silica） fire layer responds in three powerful steps: 1.Cools by evaporation: Water content absorbs massive heat as it turns to steam 2.Builds a heat shield: Silica nanoparticles lock together into a dense, strong network 3.Turns into ceramic armor: Above 800℃ it sinters into a hard ceramic layer that stops heat and stops flames, while holding glass shards in place 5. Grade Selection Made Simple Economy grade (30–40%): For interior fire doors and windows, 0.5–1.0h rating, budget-friendly Standard grade (40–50%): For fire partitions and interior walls, 1.5–2.0h rating, balanced performance Premium grade (50–55%): For high-rise and curtain wall, 2.5–3.0h rating, maximum fire protection Curtain wall grade: For exterior facade systems, enhanced weathering and bond strength 6. Packaging & Service Packaged in 25kg, 200kg drums and 1000kg IBC totes. Free samples available for testing. Technical team supports formulation tuning and on-site trial.
