Aerogel Coating for Coal Mines Underground Tunnel Lighting Project

Tunnel lighting is crucial for coal mine safety and quality standardization assessment. However, traditional materials used in client's mines caused messy tunnel appearance and inconsistent lighting effects. Our aerogel coating was applied for tunnel lighting upgrades. The standardized construction process includes: base cleaning → tunnel protection → primer application → first topcoat → second topcoat → maintenance. Our aerogel coating outperforms traditional ones in coal mine environments: 1) Anti-pollution: Hydrophobic components prevent coal dust accumulation, easy to clean with less secondary dust. 2) Scrub resistance: Over 2000 cycles, maintaining integrity for 3-5 years, saving time/labor. 3) High reflectivity: Brighter tunnels under unchanged lighting, reducing operational risks. 4) Acid-alkali resistance: Protects steel bars/bolts, avoiding safety hazards. We’ve completed 210,000㎡ projects verifying its reliability and winning user recognition.
