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.

FAQ

How about the delivery time?Lead time since receipt of 30% T/T deposit payment: 3 weeks.(Samples will be prepared within 3 days.)

2.What's are the MOQ?Generally speaking, the MOQ is one container, but we can provide you samples for quality inspection.

3. Do you charge for the samples?Accordeing to our company policy, the samples are free, we only charge the freight fee. And we will return the freight fee during the next order.

4. Can you produce according to customers' design?Sure, we are professional manufacturer, OEM and ODM are both welcome.

Q:European electrothermal?film is good: European electrothermal?film is radiant electric heating, it is ok if the room is small, but, I suggest you choose the type of entrance natural convection. .

Q:What materials does geomembrane belong to?: Foam material

Q:What are some common geomembrane installation techniques?: Some common geomembrane installation techniques include anchor trenching, which involves digging a trench around the perimeter of the area where the geomembrane will be installed and securing it with an anchor trench; floating cover installation, where the geomembrane is laid out on the surface of a pond or lagoon and anchored in place; and wedge welding, which utilizes a hot wedge tool to fuse the geomembrane panels together.

Q:Painting film thickness standard: there is no specific criteria. no matter what kind of painting you are sparying, you can not brush until the treament of coating surface, otherwise there is no way to guarantee quality. brushing by hand for 2 - 3 times. Simple brushing needs at least two sides, if advanced brush need to be able to see the film thickness, it would need the N side. brushing until you are satisfied, pay attention to the quality of spraying, and pay attention to environmental protection

Q:Is electrothermal?film useful?: It has a good performance, but it is not as good as electric mattress. As for the power consumption, a point of view should be determined: Energy is conserved, without the input of energy, it is impossible to produce heat.

Q:How do geomembranes contribute to the preservation of endangered species?: Geomembranes are synthetic membranes that are impermeable to liquids and gases, making them a useful tool in the preservation of endangered species. These membranes can be used to construct artificial habitats, such as ponds or enclosures, that mimic the natural habitats of these species. By providing a controlled environment, geomembranes help protect endangered species from predators, invasive species, and human disturbances. Additionally, geomembranes can be used to create barriers that prevent the contamination of water bodies, thus safeguarding the delicate ecosystems on which these endangered species rely. Overall, geomembranes play a crucial role in preserving the habitats and ensuring the survival of endangered species.

Q:What is the film sticking process for computer screen?: First step of film sticking: aim the film marked ① at the screen and pull the ① layer of release liner label, slowly tear a part of this layer, pay attention not to touch the adsorbed layer (middle layer) of the protective?film with fingers. Second step of film sticking: aim the adsorbed layer at the screen corner, make sure that the position is aligned, smooth the film carefully while tearing off the backing layer ① release liner. Because present protective film has electrostatic automatic adsorption function, generally it does not need be ironed too much. The action should be slow when sticking the film, and it is recommended to start sticking along the long side of the screen, from point to line, from line to surface successively

Q:Can geomembranes be used in floating covers for liquid containment?: Yes, geomembranes can be used in floating covers for liquid containment. Geomembranes are impermeable materials that are commonly used in various applications, including floating covers for liquid containment. These covers help prevent the liquid from being exposed to the atmosphere, thus reducing evaporation and contamination risks.

Q:What is the role of geomembranes in waste management?: The role of geomembranes in waste management is to act as a barrier to prevent the migration of potentially harmful substances from waste disposal sites into the surrounding environment. They are used as liners or covers for landfills, hazardous waste containment areas, and other waste management facilities. By providing a waterproof and impermeable layer, geomembranes help to protect soil and groundwater from contamination, ensuring the safe disposal of waste materials.

Q:can geomembrane reach A-class seepage-proof?: the seepage-proof effect of project composite geo-membrane is mainly depends on the interlayer, the norms of seepage-proof geomembrane is 100-1500g/square meter, in order to guarantee the good seepage-proof effect, the thickness of geomembrane should be less than 500g/ square meter, outer geotextile should be less than 300g, too thin geotextile will reduce the sand stone resisting effect, increasing geomembrane's thickness and prevent sand stone corrosion will influence the seepage-proof effect of geomembrane, composite geo-membrane's norms is less than 800g/square meter, which can reach the seepage-proof standard.
