HDPE Geomembrane Production Line

HDPE Geomembrane Production Line

I. Overview of Haoyang HDPE Geomembrane Production Line

1.1 Enterprise Strength & Line Layout

Haoyang Environmental, founded in 2008 in Dezhou, Shandong, is a national high-tech enterprise specializing in geosynthetic materials. It operates 20+ modern production lines, including the first domestic 10m-width blown film HDPE geomembrane line, with an annual capacity of 73,500 tons.

1.2 Core Position & Certification

As the first Shandong enterprise with special anti-seepage qualification and a CNAS-accredited laboratory, it leads in R&D and quality control.

1.3 Application & Global ReachProducts serve key projects (e.g., South-to-North Water Diversion) and are exported to 70+ countries, making Haoyang a core Chinese exporter. 

II. Core Raw Material System of Haoyang Production Line     

2.1 Virgin HDPE Resin Selection

Haoyang exclusively uses 100% virgin HDPE resin (97.5%+ high-density polyethylene) with stable molecular structure, ensuring excellent corrosion resistance and no pinhole defects.

2.2 Functional Additive Formulation

Anti-UV agents, antioxidants, and carbon black are proportioned via automatic batching to enhance aging resistance and low-temperature toughness.

2.3 Raw Material Preprocessing

Raw materials undergo strict drying, impurity removal, and quality inspection before feeding, matching Haoyang’s five-layer co-extrusion process requirements. 

III. Key Equipment Configuration of Haoyang Production Line

3.1 Intelligent Feeding & Mixing Unit

Composed of storage silos, PLC-controlled automatic proportioning machines, and high-speed mixers, it ensures precise metering and uniform mixing, eliminating manual errors.

3.2 Core Extrusion & Molding Equipment

The 10m-width five-layer co-extrusion die (global 首创) enables integrated molding, enhancing tensile strength and impermeability.

3.3 Cooling & Finishing System

Equipped with real-time online thickness detectors and circulating cooling calibrators, thickness error is controlled within ±0.01mm.

IV. Haoyang’s Unique Manufacturing Technologies

4.1 10m-Width Five-Layer Co-Extrusion Blown Film Technology

Molten HDPE is extruded through an annular die, inflated, and cooled to form five-layer composite geomembranes with core reinforcement and functional surfaces.

4.2 Online Double-Sided Spray Roughening Technology

A global original 10m-width online double-sided spray roughening process (2020 R&D) boosts friction coefficient, improving slope stability for mining and landfill projects.

4.3 Digital Intelligent Control Technology

The MES system + digital twin platform connects all equipment, enabling real-time data monitoring and parameter adjustment, increasing efficiency by 20%. 

V. Standard Production Workflow of Haoyang Line

5.1 Pre-Production Preparation & Debugging

Operators inspect raw materials, set temperature, traction speed, and target thickness via the PLC system, and conduct trial runs to minimize defects.

5.2 Automatic Production Process

The line runs fully automatically: feeding & mixing → high-temperature melting → five-layer co-extrusion → cooling → thickness calibration → edge trimming → winding.

5.3 Post-Production Quality Inspection

Finished products undergo strict tests (tensile strength, anti-seepage, anti-aging) in the CNAS-accredited laboratory to meet international standards. 

VI. Premium Performance Parameters of Haoyang Products

6.1 Dimensional Specification Range

Width: 2m–10m (10m as flagship); Thickness: 0.2mm–2.5mm, covering smooth and textured geomembranes.

6.2 Mechanical & Anti-Seepage Properties

Tensile strength ≥28MPa; anti-puncture strength 30% higher than national standards; excellent chemical resistance for harsh environments.

6.3 Durability & Environmental Adaptability

With anti-UV and antioxidant additives, products have a 30+ year service life underground and 10+ years outdoors.

VII. Intelligent Operation & Maintenance of Haoyang Line

7.1 Daily Intelligent Maintenance

The MES system monitors equipment status in real time, reminding maintenance for die head cleaning, bearing lubrication, and circuit inspection.

7.2 Common Fault Diagnosis & Solutions

Uneven thickness, bubbles, or edge warping are resolved by adjusting temperature, cleaning the die head, or calibrating detectors, ensuring stable production.

7.3 Professional Technical Support

Haoyang provides 24/7 online support, on-site installation, and operator training by a 30+ R&D team, ensuring long-term stable operation.
