Customizable HDPE Textured Geomembrane for Industrial and Mining
Applications
Product Introduction
Column point geomembrane is a type of impermeable material made
from high molecular polymer as the basic raw material. It not only
prevents liquid seepage but also prevents gas volatilization. This
material has a wide range of applications in construction
engineering, highway tunnels, subways, railway tunnels, industrial
and mining, and municipal underground engineering projects.
Product Properties
The characteristics of the pillar point geomembrane lie in its
surface pillar point structure, which is formed by a special mold
pressing roller, evenly distributed, both beautiful and capable of
increasing the friction coefficient. The front and back sides of
the membrane can be hot-fused into one with different materials and
colors, allowing the product's front and back sides to be set
according to geological conditions and engineering requirements in
engineering applications. This production process not only retains
the mechanical properties of the material itself, as well as good
elongation and chemical property stability, but also enhances the
product's tensile, wear resistance, and puncture resistance through
the addition of a certain proportion of functional additives. In
addition, the pillar point geomembrane has a high resistance to
acid and alkali, microbial, and chemical erosion.
Product Application
The column point geomembrane not only has the function of
imperviousness and pollution prevention in engineering laying, but
also has the function of anti-skid, which is especially suitable
for the application of engineering slope surface, and is convenient
for strengthening the adhesion degree in the secondary laying of
geotechnical fabric, with the advantage of convenient construction.
It is an ideal material for landfill site imperviousness and
pollution prevention projects. In addition, the column point
geomembrane is also widely used in the seepage prevention of the
reservoir basin and the seepage plugging and leakage prevention of
the dike, canal seepage prevention, water diversion tunnel seepage
prevention, slope protection and other fields.
In summary, column point geomembrane is a versatile impermeable
material. Its unique design and superior performance make it play
an important role in various engineering fields.
