Introduction to the application fields and characteristics of geomembrane
The use of geomembrane:
1. Environmental protection and sanitation. It effectively solves the problem of urban solid waste pollution to the environment, and can avoid continuous pollution to the environment.
2. Water conservancy projects. It is used for dam foundation reinforcement, drainage plate for groundwater drainage, diversion and depressurization, etc.
3. Municipal construction projects. Various anti-seepage projects such as soft soil foundation reinforcement and drainage.
4. Petrochemical system, chemical sewage tank anti-seepage, oil refinery sewage tank anti-seepage, electroplating pickling tank anti-seepage and anti-corrosion, pipeline lining, etc.
5. Anti-seepage diversion reinforcement under road traffic facilities and ballasts, anti-seepage reinforcement of culverts and tunnels, groundwater diversion and moisture protection of circuits.
Features of geomembrane:
1. Good physical and mechanical properties
The working environment of composite geotextile is harsh, and in many cases it is soaked in water or spread in soil with high humidity, so it must have good hydrolysis resistance and wet mechanical properties.
2. Resistance to ultraviolet radiation, hydrolysis, high and low temperature
The composite geotextile must be exposed to sunlight, so it must have the corresponding UV resistance; the composite geotextile must adapt to the temperature when it comes into contact with asphalt and other materials, and requires a higher melting point.
3. Chemical resistance, corrosion resistance and mildew resistance
Some water and soil are alkaline, some are acidic, some are salty, and some contain various elements, so they must be chemically stable.
4. Good water permeability
Geomembrane filtration and drainage require water permeability, so it must have good water permeability.
