Product Description:
Geomembranes are generally considered to be made from continuous, highly impermeable, extruded flexible sheets of either HDPE (High Density Polyethylene) or LDPE (Low Density Polyethylene). However, it is also possible to tightly weave small tape fibres of these polymers so as to achieve (either directly or by subsequent treatment) an impermeable membrane. Predominantly, the continuous extruded sheets are used for water containment or waste disposal linings. These inevitably involve the lining of soil slopes and, in order to increase the frictional characteristics of the membranes, so as to resist sliding, one or both sides of geomembranes can be provided with roughened or raised profile surfaces.
Applications:
Geomembranes have a very low coefficient of permeability - much lower than most clays and natural soils. HDPE, in particular, is highly resistant to any form of chemical or biological attack. It is also very resistant to U.V. degradation. Many geomembranes are so inert that they cannot be glued together - the chemical reactions of adhesives do not work on them - they have to be welded together by heat. Their inert nature and long life characteristics make HDPE geomembranes ideal to act as liners for liquid chemical reservoirs, fresh-water reservoirs, animal waste containers, basal linings and top capping layers for waste disposal sites. During installation, HDPE geomembrane edges are sealed to one another with a double heat welded joint. The gap between the two welds is checked for leakage using an air pressure test. Many users consider that HDPE is the ideal material for the purpose of lining water and waste disposal sites because of its proven long term stability and resistance to chemical attack, but in addition to HDPE, there is LDPE, for less demanding applications such as fresh water retention and a membrane reinforced with a polyester reinforcing fabric for use where higher in-plane stresses have to be absorbed.

- Q:What are the advantages of using geomembranes in mining operations?
- There are several advantages of using geomembranes in mining operations. Firstly, geomembranes act as a barrier to prevent the leakage of potentially harmful chemicals or pollutants into the surrounding environment, protecting both the ecosystem and human health. Secondly, these membranes provide stability to the mining site by preventing soil erosion and maintaining slope integrity. Additionally, geomembranes can be used to separate different layers of materials, facilitating efficient waste management and improving overall operational efficiency. Lastly, geomembranes are highly durable and resistant to corrosion, ensuring long-term effectiveness and cost-effectiveness in mining operations.
- Q:What is the role of geomembranes in erosion control?
- Geomembranes play a crucial role in erosion control by providing a barrier that prevents soil erosion caused by water or wind. They act as a protective layer, preventing the loss of topsoil and ensuring the stability of slopes and embankments. Additionally, geomembranes can also serve as liners for ponds, landfills, and other containment structures, preventing the migration of pollutants and protecting the environment.
- Q:What's the technology of membrane switch?
- Generally there is an insulating film between the thin white steel sheet with good elasticity and the lower plate (circuit board copper foil or other metal sheets). When the membrane switch is pressed, the white steel sheet deforms downward, and contacts with the underlying conductive plate. When it is released, the white steel sheet bounces back, and the circuit is disconnected.
- Q:What is the texture wall film
- Texture wall film is a good sense of three-dimensional, it is the liquid wallpaper with relatively strong texture
- Q:What is the difference between the matte stick membrane and HD stick membrane?
- The difference is as follows: HD stick membrane transmittance is high, after pasting it will not affect the screen display, but most are not anti fingerprint, matte film is anti fingerprint, but, after posting up, poeple will have a vague feeling when looking at the screen, now the HD anti fingerprint membrane and matte HD matte membrane is anti fingerprint and high definition.
- Q:Can geomembranes be used in decorative waterfalls and cascades?
- Yes, geomembranes can be used in decorative waterfalls and cascades. They are commonly employed as liners to prevent water leakage, provide structural support, and create a smooth surface for the cascading water. Additionally, geomembranes come in various colors and textures, allowing designers to customize the appearance of the waterfall or cascade to enhance its decorative value.
- Q:what is the uses of diamond film ?
- What is the uses of diamond film ? Diamond in the solid material is the hardest, reaching HV100GPa, with a thermal conductivity of 20W · cm-l · K-1, to 5 times that of copper, the band gap of 5.47eV, resistivity at room temperature up to 1016Ω · cm,The semiconductor material may be formed. Diamond from ultraviolet to infrared spectrum has high optical transmittance, it is an excellent corrosion-resistant materials.
- Q:Are geomembranes permeable to water?
- No, geomembranes are not permeable to water.
- Q:Characteristics of geomembrane
- Therefore, the service life period of composite geomembrane is sufficient to meet the service life period of the dam seepage-proof requirement., Ethylene / vinyl acetate copolymer (EVA), mainly including polyvinyl chloride (PVC) .hiphotos.2m added stabilizer polyethylene film, whose years of working is 30 to 40 years under sewage conditions, with small proportion, low temperature resistance, corrosion resistance, good extensibility. Composite geomembrane is a kind of soil engineering impermeable material taking plastic film as a substrate, and combined with non-woven fabrics. The service life period of geomembrane, good anti-frost?property.
