What are the Applications of MASPOWER Geomembrane in Environmental Protection Engineering

The key role of MASPOWER geomembrane is to protect soils and underground water from pollution. High-density polyethylene geomembrane (HDPE geomembrane), with its outstanding performance and diverse applications, has become a vital tool for protecting the environment. HDPE geomembrane possesses many remarkable properties. Its extremely high impermeability coefficient acts as a solid barrier, effectively preventing water penetration. Its excellent chemical stability allows it to withstand corrosion from strong acids, alkali, and oils. It also exhibits excellent heat and cold resistance, operating stably in environments as high as 70°C and as low as -70°C. Its high tensile strength meets the demands of high-standard engineering projects. Its strong weather and aging resistance ensure long-term performance, providing reliable and long-lasting protection for environmental protection projects. High-density polyethylene geomembrane (HDPE geomembrane) has become a key material in environmental protection engineering due to its excellent impermeability, corrosion resistance, high strength, and environmentally friendly properties.

HDPE geomembrane, based on high-density polyethylene (HDPE), possesses the following key properties: 1. Ultra-low permeability: Permeability coefficient ≤ 10⁻¹² cm/s, effectively preventing liquid and gas penetration and preventing the spread of pollution. 2. Corrosion and chemical resistance: Resistant to acids, alkalis, salts, organic solvents, and microbial attack, suitable for use in extreme environments. 3. High strength and durability: With a tensile strength ≥ 25 MPa and excellent tear resistance, it offers a service life of over 50 years. 4. Construction flexibility: High flexibility allows it to adapt to complex terrains, and seamless connections are achieved through hot-melt welding, ensuring efficient construction. 5. Environmental and safety: Non-toxic and odorless, it complies with environmental standards, is recyclable, and does not pollute soil or groundwater. 6. Aging resistance: Contains UV and antioxidants, making it suitable for outdoor environments and providing long-term stable performance.

3.Tailings Pond/Industrial Slag Dump Seepage Control Applications: Applications for the base, slopes, and top of dumps. Product Combination: Core Material: HDPE Geomembrane (thickness ≥ 1.5mm); Supplementary Layers: Composite Drainage Net (for rapid drainage of accumulated water), GCL Waterproof Blanket, Geotextile, Vegetated Slope Protection Net (for preventing slope erosion), Monitoring Pipe (for monitoring seepage pressure); Supporting Systems: Tailings Dam Settlement Monitor, Online Heavy Metal Monitoring Equipment. Advantages: Effectively isolates heavy metals and acidic substances in tailings; High-pressure design withstands tailings accumulation loads (up to 200 kPa); Vegetated slope protection combines ecological restoration and protection. Tailings treatment and red mud dump anti-seepage projects also rely on HDPE geomembranes. Tailings and red mud contain numerous hazardous substances, and HDPE geomembranes can isolate them from the surrounding environment, preventing the spread of contamination. Combined with a professional drainage system, it can promptly drain rainwater and other materials, preventing damage to the anti-seepage layer caused by accumulated water. Its high strength and durability can withstand the pressure and erosion of tailings and red mud, ensuring long-term stability of the anti-seepage effect.
