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

Bajo coeficiente de fricción (reduce el desgaste de la construcción);

Propiedades autolubricantes (prolongan la vida útil).

03. Chemical Barrier

Resisten la corrosión de la salmuera de alta concentración y garantizan cero fugas durante más de 20 años.

04. Physical Protection

Resistencia a la perforación del cristal resistente a la sal, resistencia al desgaste por viento y arena, adecuado para entornos extremos.

05. Stable and Durable

Amplia adaptabilidad al rango de temperaturas y envejecimiento anti-ultravioleta, cumpliendo los requisitos del ciclo de vida completo de los lagos salados.

06. Environmental Compliance

Cumplen los estrictos requisitos de las ‘Especificaciones de protección medioambiental para el desarrollo de minerales de salmuera de lago salado’ (GB/T 38582-2020).

07. Safety Reliability

Resistentes a la perforación, al desgarro y a la corrosión química, garantizan ‘cero fugas’ en entornos extremos.

08.Vida útil ultralarga

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

Resistente al asentamiento, la compactación mecánica y el estrés térmico, su estabilidad es muy superior a la de los materiales tradicionales.
