UV Resistant HDPE Smooth Geomembrane For Environmental Protection
Projects
Product Introduction
Smooth geomembrane, also known as smooth geomembrane, is a widely
used waterproof barrier geosynthetic material. The material is
based on high polymer, adding carbon black, antioxidant, anti-aging
agent, ultraviolet absorber and color masterbatch through special
formula, and using three layer co-extrusion blow molding
technology. Smooth geomemofilm has very low permeability, excellent
chemical resistance and UV resistance characteristics, and has a
very high cost performance, is the first choice of civil
engineering project seepage prevention materials, widely used in
water conservancy, environmental protection, municipal engineering,
aquaculture, sewage treatment, tailings seepage prevention,
landfill, landscape and water conservancy engineering and other
fields.
Product Properties
Excellent water resistance and aging resistance.
Product Application
Smooth surface geomembrane can be used for seepage prevention,
drainage and protection in water conservancy projects to improve
the waterproof performance and stability of the project. In
environmental protection projects, it can be used for seepage
prevention and protection of landfill sites, sewage treatment
plants and other places to reduce pollution to the environment. In
the field of construction, it can be used for waterproof and
protection of roofs, basements, swimming pools and other places to
improve the service life and safety of buildings.
