HDPE Liner for Shrimp Farming Pond Specification
Product Definition: HDPE Liner for Shrimp Farming Pond Specification
HDPE liner for shrimp farming pond specification refers to high-density polyethylene geomembrane systems engineered to provide impermeable, UV-resistant, and chemically stable lining solutions for intensive aquaculture pond construction.
Technical Parameters and Specifications
Selecting the correct HDPE liner for shrimp farming pond specification requires evaluation of thickness, tensile strength, puncture resistance, and long-term environmental durability. The following values are commonly adopted in commercial aquaculture projects.
| Parameter | Typical Value | Reference Standard |
|---|---|---|
| Thickness | 0.5 mm – 1.5 mm | ASTM D5199 |
| Density | ≥ 0.94 g/cm³ | ASTM D1505 |
| Tensile Strength (Yield) | ≥ 15 kN/m | ASTM D6693 |
| Elongation at Break | ≥ 700% | ASTM D6693 |
| Puncture Resistance | ≥ 400 N (1.0 mm) | ASTM D4833 |
| Carbon Black Content | 2.0 – 3.0% | ASTM D4218 |
| UV Resistance | ≥ 90% retained strength after exposure | ASTM D4355 |
For most intensive aquaculture systems, 0.75 mm to 1.0 mm HDPE liner for shrimp farming pond specification provides balanced cost and durability.
Structure and Material Composition
HDPE liner for shrimp farming pond specification typically consists of:
High-Density Polyethylene Resin: Primary impermeable matrix
Carbon Black Additive (2–3%): UV stabilization
Antioxidants: Thermal aging resistance
Processing Stabilizers: Long-term performance enhancement
Smooth surface liners are commonly used; textured surfaces may be specified for slope stability in large ponds.
Manufacturing Process
Raw Material Inspection: Virgin PE resin quality verification.
Batch Mixing: Controlled blending of resin and additives.
Flat Die Extrusion: Continuous sheet formation.
Calendering & Thickness Control: Precision gauge monitoring.
Surface Texturing (optional): Embossing rollers.
Cooling & Winding: Controlled tension rolling.
Quality Testing: Tensile, puncture, and density verification.
Strict thickness tolerance control (±5%) ensures compliance with HDPE liner for shrimp farming pond specification requirements.
Industry Comparison
| Liner Type | Durability | UV Resistance | Cost Level | Suitability for Shrimp Pond |
|---|---|---|---|---|
| HDPE | Excellent | High | Medium | Highly Recommended |
| LDPE | Moderate | Medium | Low | Limited |
| PVC | Good | Moderate | Medium | Conditional |
| Concrete Lining | High | High | High | Expensive |
HDPE liner for shrimp farming pond specification remains the most cost-efficient and durable solution for intensive aquaculture environments.

Core Pain Points and Solutions
1. Seepage Loss
Solution: Use ≥0.75 mm HDPE liner with proper seam welding.
2. UV Degradation
Solution: Ensure carbon black content 2–3% with certified UV testing.
3. Puncture from Subgrade Stones
Solution: Install nonwoven geotextile cushion layer (300–500 gsm).
4. Seam Leakage
Solution: Use double-track hot wedge welding and air channel testing.
Risk Warnings and Mitigation
Ensure subgrade is compacted and free of sharp objects.
Maintain minimum overlap of 100 mm for welding.
Avoid installation during heavy rain or strong wind.
Conduct vacuum or air pressure seam testing.
Provide anchor trench depth ≥500 mm.
Procurement and Selection Guide
Define pond depth and hydraulic load.
Assess soil condition and puncture risk.
Select thickness (0.5–1.5 mm) based on lifespan target.
Verify compliance with ASTM GRI-GM13 standards.
Request third-party laboratory reports.
Confirm roll width and transport logistics.
Evaluate welding equipment availability.
Calculate total area including slopes and anchor trenches.
Following these steps ensures compliance with HDPE liner for shrimp farming pond specification while minimizing operational risk.
Engineering Case Example
Project: 12-hectare coastal shrimp farming development Pond Size: 0.8–1.2 hectares per pond Water Depth: 1.5 meters Selected Material: 1.0 mm HDPE liner Cushion Layer: 400 gsm nonwoven geotextile Installation Method: Double-track wedge welding Result: Zero measurable seepage after 24 months; reduced water exchange by 30%, improving operational efficiency.
