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's the installation method of the soft film ceiling?: 1. First to go to the site to see if there is a condition of installing the keel: Look at the scene to make sure the wall is completed, and woodworking processing part is qualified, the area that need to be plastered should be completed first. First part plastering carpentry part we proposed must be in accordance with the requirements to do, to advance the processing of.2. entering the construction site conditions Licensor hole size lamp, air outlet, first part is fixed according to the design Aluminum Alloy keel keel carpentry requirements drawing well, attention must be right angle connecting to smooth, flat, dense.3. lamp holder, tuyere, light tube plate to and around the keel level, and firmly cannot swing can smooth.4. smoke, ceiling lamps, the first position to make a wooden frame, wooden frame the bottom surface should be polished, and pay attention to the level of height is too low, it is easy to show a trace of.5. before installing ceiling, carefully check the keel joints are solid and smooth, the spray head to stick on the white tape, an outlet should be well handled. When loading the smallpox to first from the middle to both sides of the fixed, while paying attention to size on both sides and pay attention to welding seam to the final straight angle position, pay attention to smooth. Around the well to the smallpox pruning removes. To perfect income effect on the edge. Turn on the light hole. To mark the position of the lamp hole , and carefully stick the PVC lamp ring carefully and accurately on the bottom of the soft film and then remove the excessive smallpox after it is firm. Find the position of the outlet and the light pipe handicap, just as the surroundings, to install the soft film to the aluminum alloy keel, pay attention to keep the angle be smooth.

Q: Are geomembranes resistant to oxidation?: Yes, geomembranes are generally resistant to oxidation due to their composition and material properties. They are designed to withstand exposure to oxidative substances and environmental conditions, making them a reliable choice for various applications that require protection against oxidation.

Q: Who knows the repair method of membrane switch?: It can only be tested with the help of schematic circuit of the membrane switch. It is usually the shift knob that goes wrong. If there is no schematic circuit, you can only find out the problem by yourself. Membrane switch is actually a trigger signal to the IC. It is mostly a line or an array. This problem is rather obvious and easy to find out, but generally when membrane switch goes wrong, there is no way to repair but switch to a new one.

Q: What are the advantages of using geomembranes in irrigation systems?: One of the advantages of using geomembranes in irrigation systems is their ability to prevent water leakage. Geomembranes act as a barrier, reducing the risk of water loss through seepage and evaporation. Additionally, they help to maintain proper soil moisture levels by preventing excess water from draining away. This can lead to more efficient water usage and improved crop yield. Geomembranes also provide a protective layer that prevents weed growth and soil erosion, further enhancing the overall effectiveness and sustainability of irrigation systems.

Q: Can geomembranes be used for waterproofing?: Yes, geomembranes can be used for waterproofing. They are thin, flexible sheets made from various materials such as synthetic polymers or rubber, and are designed to provide an impermeable barrier against water. Geomembranes are commonly used in construction projects, such as lining ponds, landfills, or tunnels, to prevent water leakage and protect the surrounding environment. They are also used for waterproofing structures like basements or roofs, ensuring that water does not penetrate through the building materials.

Q: Can geomembranes be used in underground construction?: Yes, geomembranes can be used in underground construction. They are often used as liners to prevent seepage or leakage of fluids in tunnels, underground storage tanks, and other underground structures. Geomembranes provide an impermeable barrier and help to maintain the integrity of the construction.

Q: How to separate the non woven fabric from the waterproof board?: Installation and construction of HDPE geomembrane shall be in accordance with the specific site condition and climatic conditions, properly pre-place 2%-5% extension volume; level surface mounting of base, remove the roots, stones and other sharp objects; trim round internal and external corners with its fillet radius equal to or more than 50cm; welding seam surface must be clean; welding seam should adopt displacement installation to avoid cross-wire welding, T-shape installation is available; using the side ditch anchoring landfill or bead seal installation; welding uses double track thermal melting, monorail hot melt, squeezing welding rod welding; seam take junction width is 10cm-15cm.

Q: Which one is better, oil heater or electrothermal?film?: Both oil heater and electrothermal?film are pure resistance circuit, using resistance to heat things, thus their efficiency is almost the same. Oil radiator is heated slowly and it will dissipate the heat slowly for a while after the electricity is cut off. The electrothermal?film is heated quickly and it gets clod as soon as the electricity is cut off. But the heat productivity is almost the same at the same power. Heating capacity and power consumption of the two products are the same. The electrothermal?film is smaller. The electrothermal film is recommended.

Q: What are the design considerations for geomembranes in containment systems?: Some of the key design considerations for geomembranes in containment systems include selecting the appropriate material thickness and type, considering the chemical compatibility with the contained substances, evaluating the durability and resistance to punctures and tears, ensuring proper installation techniques and quality control, accounting for site-specific conditions such as slope stability and seismic activity, and considering long-term performance and maintenance requirements. Additionally, factors like environmental regulations, cost-effectiveness, and sustainability may also influence the design choices for geomembranes in containment systems.

Q: Can geomembranes be used in reservoir liners?: Yes, geomembranes can be used in reservoir liners. They are commonly employed to provide impermeable barriers that prevent water seepage and ensure the integrity of reservoirs.
