Applications
Environmental Engineering
Landfill Liners and Caps: 1.5mm HDPE geomembrane serves as primary and secondary liners in municipal solid waste landfills, hazardous waste containment facilities, and industrial waste disposal sites. Its superior impermeability prevents leachate migration, protecting groundwater from contamination. The material's chemical resistance ensures long-term performance even when exposed to aggressive landfill leachates.
Wastewater Treatment: Used in sewage treatment plants, regulating tanks, and industrial wastewater containment ponds. The geomembrane prevents seepage of untreated wastewater into soil and groundwater, meeting environmental protection regulations.
Water Conservancy Projects
Reservoirs and Dams: Applied as anti-seepage lining materials in reservoirs, dams, and canals to minimize water loss through seepage. The 1.5mm thickness provides sufficient strength to withstand water pressure and mechanical stresses.
Irrigation Systems: Used in irrigation canals, water storage tanks, and agricultural reservoirs to improve water efficiency and prevent water loss through seepage.
Mining Industry
Tailings Ponds and Heap Leach Pads: Serves as containment liners for mining tailings ponds, heap leach pads, and processing facilities. The geomembrane prevents the migration of toxic chemicals and heavy metals into the environment, protecting soil and groundwater quality.
Agriculture and Aquaculture
Fish Ponds and Aquaculture Farms: Used as pond liners in fish farming, shrimp ponds, and other aquaculture applications. The geomembrane prevents water loss through seepage and maintains water quality by preventing soil contamination.
Agricultural Reservoirs: Applied in agricultural water storage systems to ensure efficient water management and reduce water wastage.
Industrial Applications
Chemical Plants and Oil Refineries: Used as secondary containment liners for chemical storage tanks, reaction vessels, and process areas to prevent chemical spills from contaminating soil and groundwater.
Power Plants: Applied in ash ponds, fly ash containment facilities, and other industrial waste containment systems.
Price Analysis
Market Price Range
The price of 1.5mm HDPE geomembrane varies based on several factors, including raw material quality, manufacturing standards, and order quantity. Current market prices range from:
•
Small Batch Orders (50-999 m²): $0.50-1.50 per square meter
•
Medium Batch Orders (1,000-9,999 m²): $1.50-2.50 per square meter
•
Large Batch Orders (10,000+ m²): $2.00-3.00 per square meter
•
Wholesale Price (Project Scale): $2.50-3.50 per square meter
Factors Influencing Price
Raw Material Quality: Virgin HDPE resin costs 8.07−10.76/m2,whilerecycledresincosts5.38-8.07/m². Virgin resin offers 50-100 year lifespans with lower failure risks compared to recycled materials.
Thickness: The 1.5mm thickness represents the standard for landfill liners and mining applications, offering optimal balance between cost and performance. Thicker liners (2.0mm, 2.5mm) cost 20-30% more but provide enhanced puncture resistance.
Manufacturing Standards: Products meeting GRI-GM13 and ASTM standards typically command premium prices due to guaranteed quality and performance specifications.
Order Quantity: Bulk orders benefit from volume discounts, with prices decreasing by 15-30% for large-scale projects.
Geographic Location: Transportation costs and import duties can add $0.10-0.30/m² to the final price, depending on project location.
Manufacturing Process
Raw Material Preparation
The production process begins with high-density polyethylene particles that undergo strict quality control to ensure purity and consistency. The raw materials must have excellent thermal stability, aging resistance, and puncture resistance properties.
Melt Extrusion
HDPE particles are heated and melted through melt extruders, which can be single screw, twin screw, or conical screw extruders. During this process, temperature, pressure, and screw speed are strictly controlled to ensure optimal melting quality
