High Impermeability High Tensile Strength Geomembrane Resistant To
Corrosion Of Strong Acid And Alkali Oils
Product Introduction
The smooth surface geomembrane is made of high quality raw material
high density polyethylene (HDPE) as the impermeable substrate. In
the production process, a certain amount of carbon black,
antioxidant, anti-aging agent, ultraviolet absorber and color
masterbatch are added to the special formula, and the highly
automated geomembrane equipment is refined by three-layer
co-extrusion blow molding technology.
Product Properties
1. High impermeable coefficient.
2. High tensile strength.
3. High tear resistance.
4. Good flexibility, flexibility, elasticity, adapt to the
geological uneven settlement.
5. Strong acid, alkali, oil corrosion resistance, with excellent
chemical corrosion resistance.
6. Good heat resistance and cold resistance, its environmental
adaptation range can be as low as -70, as high as 110.
7. Resistant to ultraviolet radiation.
8. Good aging resistance.
9. Good weather resistance and wide applicability to climatic
conditions.
10. Good environmental protection, good primary plastic and carbon
black particles do not contain any preservatives, so smooth
geomembrane has no pollution to water quality and soil.
11. Easy to weld, convenient installation and construction.
12. High cost performance.
Product Application
1. Water conservancy project: river embankment, lake dam, tailings
dam, sewage dam and reservoir area, drainage channels, liquid
storage pool (pit, mine), vertical core wall, slope protection,
seepage prevention, plugging, reinforcement.
2. Waste solid liquid treatment: landfill, sewage treatment plant,
power plant regulation pool, industrial, hospital solid waste
sewage or waste residue treatment field seepage prevention.
3. Municipal engineering: subway, building underground engineering,
planting roof, roof garden, sewage pipe, tunnel, tunnel and other
anti-seepage lining.
4. Aquaculture: seawater, freshwater fish and shrimp farms, etc.
5. Landscape engineering: river, reservoir, artificial lake, golf
course pond bottom, slope protection, green lawn waterproof and
moisture-proof.
6. Salt industry: salt field crystallization pool, halogen pool
cover, salt film, salt pool plastic mat film.
7. Transportation infrastructure: the foundation of roads,
highways, railways; Waterproof layer of expansive soil and
collapsible loess.
8. Petrochemical industry: chemical plants, refineries, oil storage
tank impermeability, chemical reaction tank, sedimentation tank
lining, secondary lining, etc.
9. Mining engineering: The smooth geomembrae is also very good in
the anti-seepage effect of the bottom lining of the washing pool,
pile leaching pool, ash pile, dissolution pool, sedimentation pool,
storage yard, tailings, etc.
