Hdpe Geomemebrane Liner

I. Composition of Hdpe Geomemebrane Liner

    Hdpe Geomemebrane Liner is mainly composed of 97.4% high-quality virgin high-density polyethylene (HDPE) resin, which serves as the core component to ensure its basic performance. It is supplemented with 2-3% carbon black to enhance UV resistance and aging resistance, preventing performance degradation under long-term outdoor exposure. In addition, trace amounts of antioxidants and heat stabilizers are added to improve its oxidation resistance and thermal stability during production and use, without any other additives or fillers, ensuring its purity and reliability for various engineering applications. The components are uniformly mixed and processed through advanced co-extrusion or blow-film technology to form a dense impermeable membrane.

III. Application Advantages of Hdpe Geomemebrane Liner

1. Ultra-low hydraulic permeability, with a permeability coefficient far below the standard, effectively blocking the leakage of liquids and pollutants, and ensuring reliable anti-seepage effect for long-term use. 

2. Excellent chemical resistance, capable of withstanding corrosion from acids, alkalis, salts, oils and various industrial harmful substances, suitable for complex harsh environments. 

3. High mechanical strength, including tensile, tear and puncture resistance, which can withstand foundation settlement and external load impact during construction and use. 

4. Strong UV and weather resistance, with carbon black and stabilizers to prevent aging, adapting to a wide temperature range and having a long service life of decades. 

5. Easy construction, which can be firmly connected by thermal welding, with high welding strength, simple operation and high construction efficiency. 

6. Cost-effective, lightweight, eco-friendly, non-toxic and pollution-free, reducing construction and maintenance costs while meeting environmental protection requirements.

IV. Application Scenarios of Hdpe Geomemebrane Liner

1. Municipal and industrial landfills, used for bottom and slope anti-seepage, isolating leachate to prevent soil and groundwater pollution, which is an essential material for environmental protection projects. 

2. Water conservancy projects, including reservoirs, canals, dikes and artificial lakes, used for anti-seepage and reinforcement, reducing water loss and improving project stability. 

3. Mining projects, applied to tailings dams and heap leach pads for anti-seepage, preventing heavy metal pollution from leaking into the surrounding environment. 

4. Aquaculture and agricultural fields, used for fish ponds, shrimp ponds and greenhouse soil moisture retention, preventing water and fertilizer leakage and improving breeding and planting benefits. 

5. Chemical and petrochemical industries, used for anti-seepage of chemical storage tanks and waste liquid pools, isolating harmful substances and avoiding environmental pollution.

VI. How to Cooperate with Geotextile in Application

Step 1: Clean and level the construction base, remove sharp objects such as stones and tree roots, and compact it to meet the flatness and compactness requirements to avoid damaging the materials. 

Step 2: Lay the geotextile first, spread it flat without wrinkles, and overlap the adjacent geotextile by 15-20cm, sew it firmly to form a protective layer. 

Step 3: Lay the Hdpe Geomemebrane Liner on the geotextile, keep it naturally loose, and overlap the edges by 10-15cm for subsequent welding. 

Step 4: Weld the overlapping parts of the liner with a hot wedge welding machine, and conduct air pressure testing to ensure no leakage; at the same time, avoid damaging the underlying geotextile during welding. 

Step 5: After the liner passes the inspection, lay another layer of geotextile on it as a protective layer, then backfill with soil or gravel to complete the overall construction.
