Water Proof Membrane Extrusion Line

A geomembrane sheet machine is specialized equipment used to manufacture geomembranes, which are impermeable membranes widely used in environmental, geotechnical, and civil engineering applications. These membranes are typically made from materials like HDPE (High-Density Polyethylene), LLDPE (Linear Low-Density Polyethylene), PVC (Polyvinyl Chloride), TPO

Suitable width range: 1-8mm 

thickness range: 0.5-4mm 

The geomembrane sheet machine produces large, flat sheets of geomembrane material, which are then used for applications such as landfill liners, pond liners, water containment, mining operations, and soil stabilization.

Key Components of a Geomembrane Sheet Machine

1. Extruder:

• The extruder is the core component that melts and processes the raw polymer material (e.g., HDPE, LLDPE).

• It consists of a screw and barrel that heat and mix the material to a molten state.

2. Die Head:

• The molten polymer is pushed through a flat die head to form a continuous sheet of geomembrane.

• The die head determines the width and thickness of the geomembrane.

3. Cooling System:

• After extrusion, the hot geomembrane sheet passes through a cooling system, typically using water or air, to solidify the material.

4. Calendering Rollers:

• These rolls ensure the geomembrane sheet has a uniform thickness and smooth surface.

5. Thickness Gauge:

• A thickness gauge monitors and controls the thickness of the geomembrane sheet during production.

6. Tension Control System:

• This system ensures the sheet is pulled evenly through the machine to avoid wrinkles or stretching.

7. Wind-Up Unit:

• The finished geomembrane sheet is wound into rolls for storage, transport, and later use.

1. Raw Material Feeding:

• Polymer resin and additives (e.g., UV stabilizers, antioxidants) are fed into the extruder.

2. Extrusion:

• The material is melted and homogenized in the extruder, then pushed through the die head to form a flat sheet.

3. Cooling:

• The sheet is cooled to solidify it and maintain its shape.

4. Surface Treatment:

• Some geomembranes undergo surface texturing (e.g., for improved friction properties) using embossing rollers.

5. Cutting and Winding:

• The sheet is cut to the desired length and wound into rolls.

• High Production Efficiency: Capable of producing large volumes of geomembrane sheets.

• Customization: Can produce sheets of varying thicknesses, widths, and materials.

• Consistency: Ensures uniform quality and performance of the geomembrane.

• Automation: Modern machines are highly automated, reducing labor costs and human error.

Applications of Geomembrane extrusion line

• Environmental Protection: Landfill liners, wastewater treatment ponds.

• Water Management: Reservoirs, canals, and irrigation systems.

• Mining: Heap leach pads, tailings ponds.

• Agriculture: Pond liners, silage covers.

• Civil Engineering: Tunnel linings, road construction.
