Product Introduction:
HDPE Pond Liner 1mm is a flexible waterproof barrier material made from high molecular weight polymers such as high-density polyethylene (HDPE), polyvinyl chloride (PVC), EVA, etc., through high-temperature melting, extrusion, or blow molding processes. Its core functions are anti-seepage, waterproofing, isolation, and reinforcement, widely used in civil engineering, water conservancy engineering, environmental engineering, and other fields, equivalent to covering engineering structures with a layer of "waterproof raincoat".
1. Excellent anti-seepage performance
Ultra low permeability coefficient
The anti-seepage coefficient can reach 1 × 10 ⁻¹⁷ cm/s (HDPE material), which is much lower than traditional materials (such as 1 × 10 ⁻⁷ cm/s of clay). It can effectively block the infiltration of liquids and gases, ensuring the long-term anti-seepage effect of the project.
Anti puncture and tear resistance
Smooth surface, low friction coefficient, reducing the risk of sharp object piercing; Simultaneously possessing high tensile strength (such as HDPE film tensile strength ≥ 17MPa), it can withstand external forces such as soil pressure and water flow impact.
2. Weather resistance and durability
Wide temperature range adaptability
Wide temperature range: -70 ℃ to 110 ℃, able to maintain stable physical properties even in extremely cold or high temperature environments.
UV resistance and anti-aging
Adding anti UV agents (such as carbon black) can result in a performance degradation of only 5% -10% after 20 years of exposure to sunlight, and a lifespan of up to 20-50 years.
3. Chemical stability
Anti acid and alkali corrosion
It has excellent tolerance to strong acids (pH=1), strong bases (pH=14), and salt solutions, and is suitable for lining chemical storage tanks and reaction tanks.
Anti oil stains and organic solvents
The non-polar molecular structure makes it insoluble in oil and can be exposed to diesel, gasoline, etc. for a long time without swelling or deformation.
4. High strength and flexibility
Tensile strength and elongation
The elongation at break is ≥ 450%, which can withstand deformation caused by foundation settlement or temperature changes without rupture.
Lightweight and flexible
Lightweight (about 0.9kg/㎡), bendable and foldable, easy to transport and lay; Can fit irregular base surfaces (such as slopes, curved surfaces).
5. Construction convenience
Quick laying and welding
By using hot melt welding or adhesive technology, the welding strength can reach over 90% of the base material, forming a continuous anti-seepage layer.
Adapt to complex working conditions
Construction can be carried out in humid and low-temperature environments (≥ -10 ℃) without the need for dry substrates or special equipment.
6. Environmental Protection and Safety
Non toxic and harmless materials
Compliant with environmental standards, it can be used in scenarios such as drinking water tanks and aquaculture.
Recyclable and Reusable
Waste geomembranes can be recycled and processed into plastic pellets, reducing environmental pollution and conforming to the concept of circular economy.
