Hongyue nonwoven composite geomembrane can be customized
Short Description:
Composite geomembrane (composite anti-seepage membrane) is divided into one cloth and one membrane and two cloth and one membrane, with a width of 4-6m, a weight of 200-1500g/square meter, and physical and mechanical performance indicators such as tensile strength, tear resistance, and bursting. High, the product has the characteristics of high strength, good elongation performance, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, and good impermeability. It can meet the needs of civil engineering projects such as water conservancy, municipal administration, construction, transportation, subways, tunnels, engineering construction, anti-seepage, isolation, reinforcement, and anti-crack reinforcement. It is often used for anti-seepage treatment of dams and drainage ditches, and anti-pollution treatment of garbage dumps.
Products Description
Composite geomembrane is an impervious material composed of geotextile and geomembrane, which is mainly used for impermeability. Composite geomembrane is divided into one cloth and one membrane and two cloth and one membrane, with a wide width of 4-6m, weight of 200-1500g/m2, high physical and mechanical performance indicators such as tensile, tear resistance and roof breaking. It can meet the needs of water conservancy, municipal, construction, transportation, subway, tunnel and other civil engineering. Due to the selection of polymer materials and the addition of anti-aging agents in the production process, it can be used in unconventional temperature environments.
Property
1. Waterproof and impermeable: composite geomembrane has high waterproof and impermeable performance, which can effectively prevent the penetration of groundwater and ground water;
2. High tensile strength: composite geomembrane has good tensile strength and can withstand external pressure well;
3. Aging resistance: composite geomembrane has excellent aging resistance and can maintain the strength and toughness of the material for a long time;
4. Chemical corrosion resistance: composite geomembrane has a high tolerance to chemical corrosion in the environment and is not easily affected by chemicals.
Application
1. Environmental protection: composite geomembrane can be used in environmental protection fields such as wastewater treatment, sewage treatment, landfill and hazardous waste landfill, playing a good anti-seepage effect.
2. Hydraulic engineering: composite geomembrane can be used in DAMS, reservoirs, tunnels, Bridges, seawalls and other hydraulic engineering, which can prevent leakage and pollution well.
3. Agricultural planting: composite geomembrane can be used for orchard drainage, channel cover, film cover, pond dam cover and other agricultural construction, with a good anti-seepage effect.
4. Road construction: composite geomembrane can be used in tunnel, roadbed, bridge, culvert and other road construction fields to provide a reliable solution for road waterproofing.
