- Q: Can geomembranes be used in gas barrier applications?
- Yes, geomembranes can be used in gas barrier applications. Geomembranes are impermeable liners made of synthetic materials that are designed to prevent the migration of fluids, including gases. They can effectively contain and control the movement of gases, making them suitable for applications such as landfill gas containment, biogas storage, and gas tank lining.
- Q: Are geomembranes suitable for use in reservoirs?
- Yes, geomembranes are suitable for use in reservoirs. They are often used as liners or covers in reservoirs to prevent seepage and contamination, ensuring the integrity and durability of the reservoir structure. Geomembranes offer excellent impermeability, chemical resistance, and long-term performance, making them an effective solution for maintaining water quality and minimizing water loss in reservoirs.
- Q: Why composite geo-membrane can not be used in underground garage?
- Composite geo-membrane was invented in China, applied in the The South-to-north Water Diversion Project with good anti-seepage effect. While there are no composite geo-membrane in foreign countries. It has also been widely used in subway?tunnel and other underground constructions. Of course, it can be used in underground garage , but you must choose the appropriate specifications. It is recommended to use 300g/1.0mm/300g composite geo-membrane. The following are the details. Composite geo membrane is geotechnical impermeable material made of plastic film as anti-seepage material and non-woven fabrics. Its waterproof performance mainly depends on the performance of plastic film. Impermeable plastic film at home and abroad are mainly polyvinyl chloride (PVC) and polyethylene (PE), which are Polymer chemistry flexible material with smaller proportion, good extensibility and high?adaptability?to the?deformation. Corrosion resistance, low temperature resistance, good anti-frost?property. The main mechanism is to block earth dam leakage passage by imperviousness of plastic film and bear hydraulic?pressure and adapt to deformation of dam with greater tensile strength and elongation. Non-woven geotextile is also a kind of macromolecule staple fibre chemical material shaped through acupuncturing or hot sticking, having high tensile strength and extensibility. Combined with plastic film, it can not only increases the tensile strength and anti-puncture ability of plastic film, but also increase the friction coefficient of contact surface and make the composite geo-membrane and packaging layer stable as the non-woven fabrics surface becomes rough. At the same time, they have good corrosion resistance to bacteria and chemical action, not afraid of acid, alkali, salt erosion, high seepage coefficient.
- Q: What materials are commonly used to make geomembranes?
- Some common materials used to make geomembranes include high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyvinyl chloride (PVC), and ethylene propylene diene monomer (EPDM).
- Q: What is the role of geomembranes in waste management?
- Geomembranes play a crucial role in waste management by acting as a barrier to prevent the leakage and migration of contaminants from waste storage sites. They are used to line landfills, hazardous waste containment areas, and wastewater treatment ponds, effectively sealing off the waste from the surrounding environment. This helps to protect soil, groundwater, and nearby ecosystems by containing and controlling the spread of pollutants. Additionally, geomembranes also aid in the collection and management of leachate, the liquid that is generated when water percolates through the waste, further enhancing the overall effectiveness of waste management systems.
- Q: Can the electrothermal?film be used in bathroom?
- Some of them can be used in bathrooms, but most of them can not. 1. the breakdown voltage of electrothermal?film is above 1200V, so there is no risk of breakdown in the voltage of 220V. 2. neutral line leakage current of electrothermal?film is less than 0.126mA; and that of phase line is less than 0.136mA. 3. the electrothermal?film is flame retardant which will not lead to the autoignition of electrothermal?film. 4. electrothermal film heating system belongs to low temperature radiation heating system, the surface temperature of it during operation is only 40 to 50 degrees. 5. the electrothermal film heating system has a temperature control device, the temperature controller will automatically control the entire system, when the indoor temperature meet users' requirements, the electrothermal film heating system will stop running, when the indoor temperature is lower than users' requirements, the electrothermal?film system will automatically start running.
- Q: how to use wallpaper basilemma
- it is better to use wallpaper treasure, the base of basilemma is too soft, a cut can make the wallpaper broken.
- Q: How to stick digital plate film ?
- As long as the activity area of patch, somewhere else stick not so-called, in fact not the film board with no matter, I use the cth-670 should be no film (buy back what is what, in fact there are scratches) no matter ah, anyway is not display, and not to look. Flower flower.
