Chemical Resistant HDPE Smooth Geomembrane Ideal for Complex Environments
Chemical Resistant HDPE Smooth Geomembrane Ideal for Complex Environments
Product Introduction
Smooth geomembrane, also known as smooth-surface geomembrane, is a widely used waterproof and barrier type of geosynthetic material. It is mainly made of high molecular polymer, usually using high-quality primary high-density polyethylene (HDPE) as the impervious base material. During the production process, a special formula is used to add carbon black, antioxidants, anti-aging agents, ultraviolet absorbers, and color concentrates as auxiliary materials, and it is precisely manufactured using highly automated equipment and a three-layer co-extrusion blow molding technology.
Physical characteristics
The smooth surface geomembrane has the following remarkable characteristics and advantages:
-
Extremely Low Permeability: Effectively prevents liquid penetration, suitable for occasions with high requirements for leak prevention.
-
Outstanding chemical resistance: Capable of resisting the erosion of various chemicals, suitable for a wide range of complex environments.
-
Ultraviolet Resistance: Excellent resistance to ultraviolet light, extending the service life.
-
High cost-effectiveness: Compared to other impervious materials, the smooth geomembrane has a high cost-effectiveness.
-
Wide Temperature Adaptability: Can be used under extreme temperature conditions, maintaining good performance from as low as -70°C to as high as 110°C.
-
Environmental Friendliness: Made with high-quality virgin plastic and carbon black particles, it contains no preservatives and does not pollute water or soil.
Product Application
Transparent geomembranes are widely used in various fields due to their excellent impermeability, including but not limited to:
-
Water Conservancy Projects: Such as reservoir seepage prevention and river channel management.
-
Environmental Engineering: Such as landfills, wastewater treatment, etc.
-
Municipal Engineering: Such as garden landscape construction, etc.
-
Aquaculture: such as fish pond and shrimp pond imperviousness.
-
Tailings Dam Seepage Prevention: Prevents harmful substances from seeping into groundwater sources.
-
Others: Sites requiring impervious treatment, such as chemical plants and liquid storage tanks.
