Geotextiles, by definition, are made of non-woven fabrics. Mainly used to reinforce the foundation. Geomembrane is made of high-density polyethylene and is mainly used for seepage prevention. Geotextiles are divided into woven geotextiles and non-woven geotextiles. Geotextile has excellent filtration, drainage, isolation, reinforcement, impervious, protective effect, with light weight, high tensile strength, good permeability, high temperature resistance, antifreeze, anti-aging, corrosion resistance. Geomembrane, geomembrane at construction site uses plastic film as impermeable substrate, geomembrane is a kind of polymer chemically flexible material, small specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance, frost resistance it is good.
Geomembrane is mainly used in engineering construction fields such as anti-seepage, isolation, reinforcement, crack prevention, reinforcement, horizontal drainage and other anti-seepage projects. The two can work alone, or they can be combined into one to play their respective strengths.
Geomembrane performance characteristics are as follows:
1. Geomembrane is a kind of flexible waterproof material with high anti-seepage coefficient (1?10-17 cm/s);
2, geomembrane has good heat resistance and cold resistance, the use of ambient temperature is high temperature 110 °C, low temperature -70 °C;
3, geomembrane has a good chemical stability, resistance to strong acid, alkali, oil corrosion is a good anti-corrosion material;
4, Geomembrane has a high tensile strength, so that it has a high tensile strength to meet the needs of high-standard projects;
5, geomembrane has a strong weather resistance, there is a strong anti-aging properties, can be exposed for a long time while maintaining the original performance;
6, the overall performance of geomembrane, geomembrane has a strong tensile strength and elongation at break, so that the geomembrane can be used in a variety of different geological and climatic conditions. Adapt to uneven sedimentation in geological conditions;
7, the geomembrane using high-quality raw plastic and carbon black particles does not contain any preservatives, has been used to replace pvc as a food packaging bag and plastic wrap material.
