Black fish pond protection 1.2/1.5mm ASTM standard geomembrane

Product Introduction

Black Fish Pond Protection 1.2/1.5MM ASTM standard geomembrane is a high-strength geosynthetic material specially used for water protection, such as fish ponds, artificial lakes and other water conservancy facilities. It uses high-density polyethylene with excellent anti-seepage and UV resistance, which can effectively prevent water leakage and prevent external pollutants from entering the water.

Fishpond geomembrane Features:

High-strength tensile performance: It has high tensile strength and elongation at break, and can withstand the mechanical pressure in the fish pond environment.
Corrosion resistance: Geomembrane has strong resistance to most chemicals, acids, alkalis and oils, so it is particularly suitable for environments immersed in water for a long time.
Anti-ultraviolet: Anti-UV agent is added to the surface of black geomembrane, which enhances its weather resistance in the sun and can effectively resist the erosion of ultraviolet rays.
Anti-seepage: The high-density structure of the geomembrane can effectively prevent water leakage, keep the water clean and the water level stable.
Low temperature resistance: It is suitable for low temperature environments and is not easy to become brittle or crack.

FAQ:

Q: How to choose the right geomembrane liner?

A: Consider impermeability: HDPE has the strongest impermeability and is suitable for highly polluted environments.

Consider flexibility: LLDPE and PVC are more suitable for complex terrains.

Chemical resistance: HDPE is acid and alkali resistant and suitable for the chemical industry.

UV resistance: Black HDPE has the best UV resistance.

Q: What is the construction process of geomembrane liner?

A: Foundation treatment: Clean the site to ensure that it is flat and free of sharp objects.

Laying the liner: Unfold according to design requirements to avoid wrinkles.

Welding/bonding: Use hot melt welding (HDPE/LLDPE) or adhesive bonding (PVC/EPDM).

Quality inspection: Conduct spark detection or air pressure testing to ensure no leakage.

Protective layer coverage: Lay geotextile or sand and gravel protective layer to prevent mechanical damage.

Q: How to detect the anti-seepage effect of geomembrane liner?

A: Visual inspection: Observe whether there are damage, holes or welding defects.

Spark detection (applicable to conductive geomembranes): detect tiny leaks.

Vacuum box detection: negative pressure test on welds.

Hydraulic pressure test (applicable to pools): inject water to observe leakage.

Q: How long is the service life of geomembrane liner?

A: HDPE liner: more than 50 years (under buried conditions).

Q: How to repair damaged geomembrane liner?

A: Small holes: use special patches + hot air welding or adhesives.

Large-scale damage: re-weld new membrane after cutting.

Weld crack: clean and re-weld.
