Anti-clogging Drainage Mesh

Develop innovative products

Application pain points

1.Poor corrosion resistance

The conventional drainage network has poor resistance to acid and alkali, and is prone to hydrolysis. When used in the leachate drainage systems of tailings ponds, red mud storage areas, and hazardous waste landfill sites, it is susceptible to corrosion by acid and alkali and thus may fail.

2. The pore structure is prone to clogging.

The conventional drainage network is relatively loose and has a large tension difference. After landfilling, the fine powder particles of the landfill materials invade the pores and the core of the network, causing the drainage channels to become blocked.

3. The core of the network has poor pressure resistance.

The conventional drainage network has large mesh sizes, an unstable core structure, and poor compressive strength. After being subjected to the heavy pressure of the landfill materials, it is prone to deformation, resulting in the narrowing or closure of the drainage channels.

Core advantages of the product

1.Composite barrier and silt-blocking design

Gradient filtration mechanism:

The geotextile has high modulus, high tensile strength and anti-clogging properties. The surface pore size is ≤ 0.15 mm, which can intercept sediment

while maintaining a water permeability rate of ≥ 5.0×10-2 m2/s.

2. High-pressure resistant drainage core wire

Three-dimensional rib structure

Compressive strength ≥ 830 kPa (ASTM D6364), deformation rate < 10%.

Water permeability retention rate > 80% after 100 hours.

3. Complete chemical tolerance

After being soaked in 10% sulfuric acid/NaOH for 30 days, the retention rate of tensile strength is over 90% (according to ASTM D7238).

Applicable environment: pH 2 to 12.
