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:How do geomembranes contribute to the prevention of soil erosion in agriculture?: Geomembranes contribute to the prevention of soil erosion in agriculture by providing a protective barrier between the soil and external factors such as water, wind, and chemicals. The impermeable nature of geomembranes prevents water from infiltrating the soil, reducing the risk of erosion caused by heavy rainfall or irrigation. They also prevent wind from carrying away loose soil particles, maintaining the integrity of the agricultural land. Additionally, geomembranes act as a barrier against chemicals, preventing their seepage into the soil and reducing the potential for soil degradation. Overall, geomembranes help to preserve the soil structure and fertility, mitigating the risks of erosion and promoting sustainable agriculture practices.

Q:Are geomembranes suitable for use in oil refinery containment areas?: Yes, geomembranes are suitable for use in oil refinery containment areas. Geomembranes are impermeable liners that can effectively prevent the leakage of hazardous chemicals and fluids, making them an ideal choice for containing oil and other contaminants in refinery facilities. They offer excellent chemical resistance, durability, and can withstand harsh environmental conditions, ensuring the safety and integrity of containment areas in oil refineries.

Q:How do geomembranes contribute to water storage reservoirs?: Geomembranes contribute to water storage reservoirs by providing a reliable and efficient barrier to prevent seepage and leakage of water. They act as impermeable liners, ensuring that the stored water is contained within the reservoir, minimizing the risk of water loss due to infiltration. This helps in maintaining the desired water levels and preventing water scarcity. Additionally, geomembranes also protect against contamination, preserving the quality of the stored water.

Q:Geomembrane is used for anti-seepage system which layer structure? What are the materials for the anti-seepage system?: Cement concrete above, but impervious material on the 30 cm or so to protect the layer, so as to ensure that the geomembrane waterproof seepage better!

Q:What kind of membrane switch material is good?: It is a kind of normally open switch and its up and down contacts are in a off state under normal circumstances. When the membrane switch is pressed, the upper circuit contact deforms downward, and realize the contact with the lower circuit plate and breakover. When you release your finger, the upper circuit contact will bounce back, the circuit is off, and the loop will trigger a signal. Membrane switch is rigorous in structure with nice appearance and good seal.

Q:slope geomembrane sliding treatment program: Using rough exasperate geomembrane, national standard have technical requirements for the exasperate geomembrane of side slope: CJ / T 234-2006 refuse landfill can use the high density polyethylene geomembrane

Q:Which is better between electric?hot?plate and electrothermal?film?: It depends on actual situation, which can not be directly determined which one is good. The electrothermal?film is a kind of exothermic material made of special conductive macromolecule material matched with metal current-carrying strip, hot melted between the insulating film bodies, which will produce heat after being electrified Mainly used for heating element. The electric hot plate is equippment taking electric heating alloy wire as heating material, and mica soft board as insulating material, and wrapping thin metal plate (aluminum plate, stainless steel plate, etc) in the surface for heating. Typical applications like electric hot water bottles. Casting metal tubular electric heating element in aluminum plate/aluminum plate or welding or inlaying on the aluminum plate/aluminum plate to form electrical heating plate of all shapes. Typical application like electric cookers, electric irons, electric coffee makers, etc.. ! ~

Q:How do geomembranes help in groundwater recharge projects?: Geomembranes help in groundwater recharge projects by acting as a barrier to prevent water from seeping through the ground too quickly. By lining the recharge ponds or basins with geomembranes, the water can be retained for a longer period, allowing it to percolate into the ground and recharge the groundwater aquifers. This helps increase the water storage capacity of the aquifers and ensures a sustainable supply of groundwater for various uses, such as drinking water or irrigation.

Q:How do geomembranes prevent water leakage?: Geomembranes prevent water leakage by acting as a barrier between the soil or substrate and the surrounding environment. These synthetic membranes are impermeable to water and provide a reliable solution for containing liquids or preventing water seepage in various applications.
