Thickness: The thickness of HDPE geomembrane is usually measured in millimeters (mm). Common thicknesses are 0.5mm, 0.75mm, 1.0mm, etc.
Width: The width of HDPE geomembrane is usually measured in meters (m). Common widths are 2m, 4m, 6m, etc.
Length: The length of HDPE geomembrane is usually measured in meters (m) and can be customized according to project needs. Common lengths are 50m, 100m, 200m, etc.
2. Technical indicators
The technical indicators of HDPE geomembrane mainly include the following aspects:
Tensile Strength: The tensile strength of HDPE geomembrane refers to the maximum tensile force it can withstand during the stretching process, usually expressed in megapascals (MPa).
Elongation at Break: The elongation at break of HDPE geomembrane refers to the elongation in the length direction when tensile failure occurs, usually expressed as a percentage (%).
Tear Resistance: The tear strength of HDPE geomembrane refers to its resistance when subjected to tearing force, usually expressed in Newton (N).
Puncture Resistance: The puncture resistance of HDPE geomembrane refers to its ability to resist puncture by external sharp objects, usually expressed in Newton (N).
3. Application scope
The specifications of HDPE geomembrane are suitable for various engineering application scenarios:
Water conservancy projects: Used as anti-seepage layers in water conservancy projects such as reservoirs, canals, and rivers.
Environmental Engineering: Used as anti-penetration layer in environmental projects such as landfills and sewage treatment plants.
Traffic Engineering: Used as waterproof and anti-penetration layer in traffic projects such as highways and railways to protect the basic soil.
4. Advantages and Development Trends
HDPE geomembrane has the advantages of good anti-penetration performance, strong durability, and convenient construction, and has gradually become one of the mainstream products among geosynthetic materials. In the future, with the continuous advancement of technology and the increase in market demand, the specifications of ordinary HDPE geomembranes will become more and more diversified, and their application scope will be further expanded to provide more reliable anti-penetration protection for various projects.
Conclusion
The above is a detailed introduction to the specifications of HDPE geomembrane. I hope it can provide you with some reference and help. As a high-quality geosynthetic material, HDPE geomembrane has broad application prospects and important social significance, and will play an important role in various projects.
