Deskripsi

I. Ikhtisar Produk

The high – strength textured HDPE geomembrane, also known as rough geomembrane, is a top – notch anti – seepage material. We manufacture it using high – quality virgin high – density polyethylene (HDPE) resin through an advanced co – extrusion blow – molding process.

This process, combined with a patented texturing technology, endows its surface with uniformly stable rough textures. While keeping the excellent anti – seepage performance typical of HDPE materials, it significantly enhances the interfacial friction coefficient. The friction angle ranges from 30° to 35°, making it especially suitable for steep – slope anti – seepage projects. Also, the carbon black content in the raw material lies between 2.0% and 3.0%, ensuring outstanding resistance to ultraviolet aging.

II. Key Advantages

Anti – Slip Performance: The special textured surface treatment of the textured HDPE geomembrane boosts the interfacial friction coefficient by over 50%. It effectively prevents the sliding of slope lining systems, ensuring stability and safety. For example, in landfill slope projects, this anti – slip feature is crucial for maintaining the integrity of the anti – seepage system.
Mechanical Strength: With a tensile yield strength of ≥22 N/mm and a tear resistance of ≥190 N, this rough geomembrane meets stringent engineering requirements. It can withstand heavy loads or external forces without damage, providing reliable protection.
Flexibility: The elongation at break of this geomembrane is ≥700%. This high flexibility allows it to adapt to foundation deformation without cracking. In areas where the ground may shift or settle, it can stretch and conform to the changes, maintaining its anti – seepage function.

IV. Typical Applications

Environmental Geotechnical Engineering: We widely use the textured HDPE geomembrane for anti – seepage in slopes and bases of landfills. It also serves as lining systems for hazardous waste disposal sites. Its excellent anti – seepage and anti – slip properties ensure the safe containment of waste materials, preventing environmental pollution.
Mining Engineering: In mining projects, we use this rough geomembrane as anti – seepage linings for tailings ponds, heap leaching pads, and solution ponds. It helps prevent the leakage of mining solutions and tailings, protecting the surrounding water sources and soil from contamination.
Water Conservancy Engineering: For water conservancy projects such as reservoirs, channels, and dams, the textured HDPE geomembrane provides reliable anti – seepage protection. It helps maintain the water storage capacity of these facilities and prevents water loss due to seepage.
