0.75mm Aquaculture Pond Liner
1. The thickness is highly adaptable, balancing toughness and ease of construction, enabling it to easily cover the complex terrain of the pond.
2. The waterproofing effect is excellent, effectively locking in the water body and reducing leakage losses.
3. Weather-resistant and corrosion-resistant, it can withstand the high temperatures in Africa, ultraviolet rays, and the acid and alkali erosion of the water body.
4. The smooth surface is not prone to the growth of algae and silt, making cleaning and maintenance convenient.
1. Composition of Geomembrane
0.75mm aquaculture pond geomembrane mainly uses high-density polyethylene (HDPE) as raw material, adding anti-aging, anti-ultraviolet and other additives. It is made by extrusion molding, with uniform thickness, compact structure, and strong waterproof and anti-seepage performance, suitable for aquaculture scenarios.
2. Physical Properties of Geomembrane
The 0.75mm geomembrane has excellent physical properties. It has appropriate tensile strength and elongation at break, good puncture resistance, and can adapt to the slight deformation of the pond base. Its density is stable, and the unit area quality meets the engineering requirements, ensuring long-term use in aquaculture.
Physical Property Specification Unit Thickness 0.75 ± 0.05 mm Tensile Strength (MD/TD) ≥ 18/16 MPa Elongation at Break (MD/TD) ≥ 400/350 % Puncture Resistance ≥ 300 N Density 0.94 - 0.96 g/cm³
The 0.75mm geomembrane has good chemical stability. It is resistant to corrosion by weak acids, weak bases, and common salts in aquaculture water, and does not react with water quality components. It can resist the erosion of microorganisms in water and is not easy to decompose, ensuring no pollution to aquaculture organisms.
| Chemical Property | Performance | Test Condition |
| Resistance to Weak Acid (5% HCl) | No obvious change | 25℃, 72h |
| Resistance to Weak Alkali (5% NaOH) | No swelling, no cracking | 25℃, 72h |
| Resistance to Salt Solution (3% NaCl) | Stable performance | 25℃, 72h |
| Resistance to Microorganisms | No biodegradation | Aquaculture water environment |
| Chemical Inertness | No reaction with water components | Normal aquaculture temperature |
4. Application Fields

5. Installation Steps of Geomembrane
Base Treatment: Clean the pond base, remove stones, roots and other sharp objects, level the ground, and compact it to prevent the geomembrane from being punctured.
Geomembrane Unfolding: Unfold the geomembrane in the direction of the pond, keep it flat, and avoid folding and wrinkling.
Lap Joint Treatment: Lap adjacent geomembranes by 10 - 15cm, and clean the lap surface to ensure no dust and water.
Welding Operation: Use a hot wedge welding machine to weld the lap joints, control the welding temperature and speed, and ensure the weld is firm and leak - proof.
Quality Inspection: Check the welds by air pressure test. If there is air leakage, repair it in time, and then conduct an overall inspection to confirm the installation quality.

6. Global Application Cases
Brazil: In Amazon aquaculture areas, 0.75mm geomembranes are used to build tilapia ponds, reducing water seepage by 80% and increasing output by 30%.
India: In coastal shrimp farms, it resists seawater erosion, maintains stable water quality, and reduces the incidence of shrimp diseases by 25%.
Kenya: In freshwater fish ponds in arid areas, it saves water resources, ensures continuous aquaculture, and improves farmers' income.
Australia: In saltwater crab breeding ponds, it isolates the seabed soil, prevents crab holes from causing water leakage, and ensures the breeding environment is stable.
7. Advantages of Haoyang Environment in Geomembrane Production
High - quality Raw Materials: Adopt imported HDPE raw materials to ensure the basic performance of geomembranes is stable.
