Geomembrane for Salt Lake Mine | ISO9001

Pain Points of Conventional Geomembrane Applications

High salt content corrosion:High concentrations of sulfates, chlorides, and other substances in salt lake brines accelerate the aging of HDPE geomembrane. Long-term immersion can cause local swelling or a decrease in chemical stability.

Erosion in acidic/alkaline media:

Acidic mine wastewater (pH < 3) or alkaline salt lake environments cause micro-pores in permeable membrane materials and the precipitation of additives, reducing their flexibility and impermeability.

Insufficient puncture resistance.

The salt crystals at the bottom of the salt lake are sharp, and the mine waste rocks have many sharp edges. HDPE geomembranes (especially those with a thickness <1.5mm) are prone to puncture and thus require reliance on composite geotextiles or additional protective layers.

Features of Special Geomembranes for Salt Lake Mine

01. Comparison with traditional geomembranes

Geomembrane Tensile performance is improved by 20%, impact resistance by 60%, puncture resistance by 50%, and wear volume is reduced by 3 times.

02. Additional Advantages

Koefisien gesekan yang rendah (mengurangi keausan konstruksi);

sifat melumasi sendiri (memperpanjang masa pakai).

03. Chemical Barrier

Menahan korosi dari air garam konsentrasi tinggi dan memastikan tidak ada kebocoran selama lebih dari 20 tahun.

04. Physical Protection

Tahan tusukan kristal tahan garam, tahan terhadap angin dan pasir, cocok untuk lingkungan yang ekstrem.

05. Stable and Durable

Kemampuan beradaptasi dengan rentang suhu yang luas ditambah penuaan anti ultraviolet, memenuhi persyaratan siklus hidup penuh danau garam.

06. Environmental Compliance

Memenuhi persyaratan ketat dari ‘Spesifikasi Perlindungan Lingkungan untuk Pengembangan Mineral Air Asin Salt Lake’ (GB/T 38582-2020).

07. Safety Reliability

Tahan tusukan, tahan sobek, dan tahan korosi kimiawi, memastikan ‘tidak ada kebocoran’ di lingkungan yang ekstrem.

08. Umur Sangat Panjang

It has excellent wear resistance and anti-aging properties, which are synchronized with the mine operation cycle, thus avoiding mid-term replacement.

09. Adapt to Complex Loads

Tahan terhadap penurunan, pemadatan mekanis, dan tekanan suhu, stabilitasnya jauh lebih unggul daripada material tradisional.
