Virgin Resin HDPE Black Anti UV Anti Seepage 1mm 40Mil Salt HDPE Geomembrane Liner Saltwater Pool Cover

Key Advantages of Yixing Shenzhou HDPE Geomembrane Liners in Salt Works:

1.Prevents Seepage and Maximizes Yield:

Benefit: This is the primary reason for its use. By preventing concentrated brine from seeping into the ground,

the liner ensures that virtually all dissolved salt is recovered as a product. This dramatically increases

the yield from the same area of land.

2.Produces High-Purity Salt:

Benefit: The HDPE liner creates a clean, inert barrier between the brine and the underlying soil.

This prevents contamination from dirt, clay, heavy metals, or other impurities. The result is salt of

a much higher chemical and visual purity (often brilliant white).

3.Improves Operational Efficiency and Reduces Costs:

Benefit: Lined ponds reach saturation much faster than earthen ponds because energy from the sun

goes directly into evaporation, not into heating the ground or being lost to seepage.

Cleaning: After harvest, the smooth surface allows for easy and complete removal of the salt layer.

The pond can be quickly rinsed and refilled, ready for the next production cycle.

4.Durability in a Harsh Environment:

Benefit: The salt production environment is extremely aggressive, featuring:

High Salinity: HDPE is completely resistant to salt (NaCl).

UV Exposure: Ponds are in open, sunny areas. The carbon black in HDPE provides

excellent UV resistance, preventing degradation.

Temperature Fluctuations: HDPE remains flexible across a wide temperature range.

Physical Stresses: High puncture resistance withstands foot traffic and harvesting equipment.

5.Protects Groundwater:

Benefit: The liner prevents the hyper-saline brine from contaminating freshwater aquifers,

which is a critical environmental protection measure.

Key Points for Salt HDPE Geomembrane Liner Works:

Liner Color - Black is Standard:

Why? The black color, achieved with carbon black, is crucial.

It absorbs solar radiation, heating the brine and significantly accelerating the evaporation rate.

This is a major operational advantage.

Material Quality:
It is essential to use a high-quality, virgin resin HDPE with a high carbon black content (typically 2-3%)

for optimal UV resistance. The material must also have excellent Stress Crack Resistance (specify a grade like PE4710).

Thickness and Strength:
Given the large area and potential for physical stress during harvesting,

a robust thickness is used, typically in the range of 1.0 mm to 2.0 mm (40 to 80 mil).

Installation is Key:
Subgrade: Must be smooth, compacted, and free of sharp objects.

A geotextile underlay is highly recommended for added protection.

Seaming: All field seams must be thermally fused by certified welders and tested

to ensure a completely watertight system. A single leak can cause significant salt loss and groundwater contamination.

Anchoring: Proper anchorage in perimeter trenches is vital to hold the liner in place against wind and water pressure.

Salt HDPE Geomembrane Liner  Installation and Maintenance :

Subgrade Preparation: The earth must be properly compacted, smooth, and free of all sharp

objects (roots, rocks). This is the most critical step for a successful installation.

Expert Seaming:

All field seams must be made by certified welders using thermal fusion (wedge or extrusion) and tested rigorously

(e.g., air pressure, vacuum box) to ensure a watertight seal.

Anchoring:

The liner must be securely anchored in a perimeter trench ("anchor trench") to hold it in place when the pond is filled.

Cleaning and Disinfection:

Between cycles, the liner can be pressure-washed and disinfected with approved chemicals

(e.g., chlorine, potassium permanganate) that are compatible with HDPE.
