Frequently Asked Questions
Q
What is the main difference between HDPE and LDPE geomembranes?
HDPE provides higher tensile strength, chemical resistance, and thermal endurance, making it ideal for waste containment and demanding industrial liners. LDPE and LLDPE offer superior flexibility and elongation, making them better suited for uneven terrains and projects requiring high pliability.
Q
What are the primary applications of earthwork films?
These liners are widely applied in civil engineering, water conservancy, environmental protection, landfills, artificial lakes, mining heap leach pads, and containment reservoirs to prevent liquid migration and seepage.
Q
How is the durability and UV resistance of the geomembranes ensured?
High-quality virgin polyethylene resins are formulated with carbon black, antioxidants, and UV stabilizers during the extrusion process to provide long-term resistance against weathering and solar exposure.
Q
What is the advantage of using double-color geomembrane sheets?
Double-color geomembranes usually have a light-colored surface (such as white or green) that reflects sunlight to reduce surface temperatures, assist in leak and damage detection, and provide improved aesthetic integration into landscape environments.
Q
How are polyethylene earthwork liners connected during installation?
Liners are commonly welded using dual-track hot wedge welding equipment for long seams, while extrusion welding is utilized for detailing, patches, and pipe penetrations to ensure a secure and leak-proof seal.
