Salt Lake Geomembrane Liner for Brine & Mineral Protection

Qinghai Salt Lake faces severe anti-seepage challenges. Highly corrosive brine, a 70°C temperature swing between day and night, and high-intensity ultraviolet radiation cause traditional anti-seepage materials to rapidly age and fail, resulting in the loss of tens of thousands of tons of salt resources annually and increasingly severe salinization of the surrounding soil.

HDPE geomembrane: Customizable, superior quality

Core material selection:

Key Technical Guarantees:

Weather-Resistant Formula: UV absorbers extend oxidation induction time >100 minutes, resisting UV aging.

Precision Welding: TH-50L welder achieves weld strength >90% of base material, ensuring layer integrity.

All-Terrain Adaptability: Steep slope anchoring tech handles slopes <45°, maintaining stability.

Strict Quality Control:

Comprehensive testing from raw materials (intrinsic viscosity) to finished products (permeability) and post-construction (100% weld tightness) guarantees a leak-proof system.

Qinghai Salt Lake Anti-Seepage Project Highlights:

Scope: 320,000 m² in Qaidam Basin.

Solution: Double-welded 2.0mm HDPE membrane + 4000g/m² bentonite blanket.

Outcome: Passed 72-hour water pressure test initially, operates stably for 3 years, achieving permeability <1×10⁻¹¹m/s, effectively protecting resources and ecology.

Significant Achievements:

• Resource Protection: Prevents saltwater seepage, improves salt resource recovery, and reduces production costs.
• Ecological Protection: Prevents soil salinization and groundwater contamination, safeguarding the stability of the surrounding ecosystem.
• Economic Benefits: Reduces maintenance costs, extends the life of the salt lake, and enhances the company’s economic returns.
