Composite Geomembrane Anti-Aging And Corrosion Resistant For
Various Environments
Product Introduction
Geosynthetic membranes are impermeable materials made by combining
plastic films as the base material for impermeability with
non-woven fabrics. Their impermeability mainly depends on the
impermeability of the plastic film. Polyethylene (PE) is a high
molecular weight chemical flexible material with low density,
strong extensibility, high adaptability to deformation, corrosion
resistance, low temperature resistance, and good frost resistance.
Due to its excellent properties, composite geosynthetic membranes
are widely used in various water conservancy projects for
impermeability, such as river channel seepage control projects,
river management projects, artificial lake seepage control
projects, landscape lake seepage control projects, dam seepage
control projects, canal seepage control projects, etc.
Product Properties
* Good anti-seepage and waterproof performance
* Good elasticity and the ability to adapt to the deformation
* Good ageing resistance, corrosion resistance ability
* Under high temperature use and long service life
Product Application
1. High puncture resistance and large coefficient of friction
2. Excellent resistance to aging, wide range of ambient temperature
adaptability
3. Excellent drainage resistance
Construction
* For laying geomembrane, edge welding bead lap width 80mm-100mm,
juncture place cannot have dirt, moisture, dust, etc
* Adjust two sides of geomembrane before welding seams ,keep a
certain wedling width, and smooth without creasing.
* More details refer geomembrane construction scheme
