Performance of geomembranes under different environmental conditions
The performance of geomembrane in different environmental conditions has certain adaptability and stability. We can summarize the following points:
1 High permeability coefficient and temperature resistance: the geomembrane has high permeability coefficient (110-17 cm/s), good heat resistance and cold resistance, and the working environment temperature can reach 110 C to-70 C.
2 chemical stability: the geomembrane has excellent chemical stability, and can resist the corrosion of strong acid, strong alkali, oil and tar and other chemical media.
3 Tensile strength and ductility: the geomembrane has high tensile strength and significant ductility, which enables it to withstand large tensile force and strain, and adapt to a variety of harsh geological and climatic conditions.
4 aging resistance and ultraviolet resistance: geomembrane has strong weather resistance and anti-aging performance, can be used for a long time to maintain the original performance, while having good aging resistance, anti-ultraviolet ability.
5 the influence of environmental factors: geomembrane exposed to outdoor environment, will be affected by ultraviolet light, temperature changes, chemical substances and other factors, these factors may accelerate the aging process of geomembrane, leading to deformation or performance decline.
6. Complexity of geological environment: In areas with complex geological structure, such as high mountains and mountains, the performance of geomembrane may be affected, because there are geological problems such as brittle rock and fault uplift in these areas.
7. Selection of engineering environmental conditions: according to the different engineering environment, such as soil quality, climate conditions, groundwater level, etc., it is necessary to choose different materials and specifications of HDPE geomembrane, to ensure that its performance meets the specific needs.
Homembrane shows good adaptability and stability under different environmental conditions, but its performance can also be influenced by environmental factors and geological conditions.
