Waterproof And Anti-Seepage HDPE Smooth Geomembrane For Civil Engineering Projects
Product Introduction
Smooth geomembrane, also known as smooth geomembrane, is a widely used waterproof barrier geosynthetic material. The material is based on high molecular polymer, adding carbon black, antioxidant, anti-aging agent, ultraviolet absorber and color masterbatch and other auxiliary materials through special formula.
Product Properties
1. Low permeability: Smooth geomembrane has extremely low permeability, which can effectively prevent the passage of water and pollutants.
2. Chemical and ultraviolet resistance: Excellent chemical and ultraviolet resistance make the material resistant to various chemical substances and prolonged exposure to sunlight.
3. High cost performance: Compared with other similar products, smooth geomemofilm has a higher cost performance, is the first choice for civil engineering seepage prevention materials.
4. Strong adaptability: wide temperature adaptability, can be used in extreme weather conditions.
Product Application
1. Water conservancy and environmental protection: applied to the anti-seepage reinforcement of river dikes, lake DAMS, tailings DAMS, etc.
2. Municipal engineering: such as subway, building underground engineering, planting roof anti-seepage lining.
3. Aquaculture: Suitable for seawater, freshwater fish and shrimp farms.
4. Garden engineering: It can be used for waterproofing and moisture-proof of river, reservoir, artificial lake, etc.
5. Salt industry: salt field crystallization tank, halogen tank cover and other occasions.
6. Transportation infrastructure: waterproof layer of highway, railway foundation, etc.
7. Petrochemical industry: chemical plants, refineries, oil storage tank anti-seepage lining, etc.
8. Mining engineering: the bottom lining of washing pool, pile leaching pool, etc.
