HDPE Smooth Geomembrane The Durable and UV-Resistant Material for
Tailings Dam Seepage Prevention and Landfill
Product Introduction
Smooth geomembrane, also known as smooth geosynthetic membrane, is
a widely used waterproof and barrier type of geosynthetic material
made from high molecular polymer as the basic raw material. Here is
a detailed introduction to smooth geomembranes:
Material Composition and Properties
The smooth surface geomembrane uses high-quality original
high-density polyethylene (HDPE) as the impervious base material.
In the production process, a certain amount of carbon black,
antioxidants, anti-aging agents, ultraviolet absorbers and color
masterbatches are added using a special formula. It is then
mass-produced by a highly automated geomembrane equipment using a
three-layer co-extrusion blow molding technology.
Function and Application
Text: Smooth geomembrane has extremely low permeability, excellent
chemical resistance and UV resistance, and offers a high
cost-performance ratio, making it the preferred material for
impervious projects in civil engineering. It is widely used in
water conservancy, environmental protection, municipal engineering,
aquaculture, sewage treatment, tailings dam seepage prevention,
landfill, landscape gardening, and hydraulic engineering.
Environmental friendliness
High-quality native plastics and carbon black particles do not
contain any preservatives and do not pollute water and soil, so the
smooth geomembrane has good environmental protection.
To sum up, the smooth surface geomembrane plays an important role
in modern engineering construction due to its excellent waterproof
and seepage-proof performance and wide applicability.
