Steel Structure Ice Armor - Gluing the Great Wall - Juhuan Fireproof Foam Adhesive Safeguards the Antarctic Research Station

Deadly Challenges of Polar Survival

The Antarctic research station is exposed to extreme cold of -60℃, strong winds of up to 17 levels (65m/s), and year-round snow loads. Traditional sealing materials tend to become brittle and crack. The Chinese Qinnling Station has adopted Juhuan B1-rated flame-retardant foam adhesive system, which has passed three polar-specific certifications:

•Ultra-low temperature activity: Curing time≤45 minutes at -55℃, maintaining a bonding strength of≥3.2MPa

•Wind and snow load buffering: Closed-cell rate > 95%, providing a flexible seismic layer for steel structures and reducing wind noise transmission by 62%

•Dual-mode flame retardancy: Certified to GB8624-2025 B1 standard, upon exposure to open flame:

▶Forms a 0.8mm carbonized layer on the surface, with an oxygen index≥32%

▶Releases nitrogen to block the combustion chain reaction, self-extinguishing within 1 second after flame removal

Project milestones

This technology has been applied to the modular cabin renovation of Kunlun Station, achieving:

•Joint air tightness of 0.02m³/(h·m²), surpassing the German DIN standard

•Combined with aerogel insulation system, overall energy consumption reduced by 55%

•Awarded the "Polar Green Building Materials" certification by the Antarctic Treaty Organization

"This is not an ordinary caulking adhesive; it's like putting on a 'breathable fireproof armor' for the steel Great Wall," emphasized the project's chief engineer during the acceptance inspection.
