3D Geonet Production Line

A three-dimensional drainage network (also known as a three-dimensional geotextile drainage board, tunnel drainage water board, or drainage water board) is composed of a three-dimensional plastic mesh with one side bonded with a filter geotextile and the other side bonded with an anti-seepage geomembrane. It can replace traditional sand and gravel layers and is mainly used for drainage in landfills, roadbeds, and tunnel walls.

Characteristics of 3D Geonet Production Line

1.When the load is 720kPa and the gradient is 2%, the permeability is 2500m/d and the flow rate is 13pm/m.

2. After withstanding a load of 1200kPa for 10000 hours, the creep test retained over 60% of its thickness.

3. The carbon black content of the three rib drainage network core is not less than 2%, the density is 0.94g/cm3, the tensile strength is not less than 36.5kN/m, the melt index is 1.0 g/10min, and the thickness is 7.6mm.

4. The non-woven geotextile has an apparent pore size of 0.18mm, a permeability of 0.26 Sec-1, a permeability of 0.2cm/sec, a puncture strength of 580N, a trapezoidal tear strength of 356 N, a grip tensile strength of 900 N, a grip tensile strength of 50%, and a burst strength of 2750kPa.
