Q:Can PET film be used as thin film of the case sealing tape?: It can not. PE tape is made from polyethylene and the film is soft and has low intensity, and it is commonly used in the field of protective film. PET tape, made from polyester and the film has high strength and good insulation performance, and it is commonly used in the insulation of electrical and electronic products.

Q:Construction technology of geomembrane:: Notes for geomembrane joints: (1) the joint treatment of the geomembrane is the key process of construction, which directly affects the service life of the project. Indicated by quality test, hot weiding is an ideal way. (special adhesive is also available). Heat welding method is heating the surface which is connected with the PE geomembrane, the surface melting, and then through the pressure to merge them into one, (2) Geomembrane shall be paved along a certain direction, on both sides of the geomembrane should be reserved for certain PE membrane and PET membrane bonding layer.While paving, we should adjust the tendency of geomembrane of each unit, in order to bring convenience to two units geomembrane welding. (3) Press geomembrane with sand bags to prevent wind after pavement, edge joints requires no dirt, moisture, dust, etc.. (4) before welding, adjust the joint at two sides of PE membrane, jointing them with broadband, and making them smooth, and no wrinkle. (5) When welding, it is better to have a technical personnel of certain experience, and use a special welding machine for welding. Adjust the temperature and speed, (can also use adhesive to bond). According to many years of practice, it is proved that the thickness of the geomembrane is not less than 0.25mm, because too thin is possible to produce porosity, and it is easy to be damaged in the construction to reduce the seepage control effect. During the construction of geomembrane, we should pay special attention that the pavement should not be too tight, shouldn't wrinkle, and the jointing should be firm. We should construct strictly according to the technical specifications, checking five quality clearance comprising preparation, paving, splicing joints, testing and backfill.

Q:How do geomembranes help in preventing groundwater pollution?: Geomembranes help in preventing groundwater pollution by acting as a barrier between potential contaminants and the underlying groundwater. These impermeable liners are designed to prevent the migration of pollutants, such as chemicals or waste, into the groundwater system. By effectively containing and isolating these substances, geomembranes play a crucial role in safeguarding the quality and integrity of groundwater resources, thereby preventing pollution and protecting the environment and human health.

Q:Is it useful to stick film for iPhone?: Sticking film is to protect the phone's touch screen. Any people who loves their phones will stick film. 1. High-definition film is thin, and the visual effect is good. However, it is easily scratched; 2. Frosted film is also thin, but its visual effect is not so good without fingerprint; 3. Tempered film is thinner, and its visual effect is good and resistant to scratch.

Q:Does the lower geotextile of composite geomembrane need seaming?: In general, it does not need to seam (extending and folding together is ok). You only need to weld the geomembrane and seam the upper geotextile with handheld sewing machine. Geotextile is used as a protective layer of geomembrane to protect the impervious layer from being damaged. In order to reduce the ultraviolet radiation and increase the anti aging performance, you'd better use buried laying method. During construction, first, level cardinal plane with small sand or clay, then pave. Do not stretch too tight when paving. Both ends buried in soil is corrugated. Finally, pave a transition layer of about 10cm with fine sand or clay on two cloths and one membrane and build scour prevention layer with 20-30cm stone (or precast concrete block). In construction, you'd better build the packaging layer while paving membrane edge to try to avoid the stones hit directly on it. The connection between two cloths and one membrane and surrounding structures should be anchored by expansion bolt and steel plate depression bar, painted with emulsified?asphalt (2mm thick) to stick and prevent leakage. Construction joint treatment is a key process, which directly affects the anti-seepage effect. General joint methods are: ① lap: lap width should be larger than 15cm; ② hot?welding: suitable for thicker geomembrane substrates, and lap width of weld should be not less than 5cm.

Q:Are geomembranes easy to maintain?: Yes, geomembranes are generally easy to maintain. They require regular inspection and cleaning, but their durable and flexible nature makes them relatively low maintenance. Additionally, any minor damages or leaks can be easily repaired using patching techniques.

Q:What are the quality control measures for geomembrane installations?: Some quality control measures for geomembrane installations include conducting thorough site inspections before installation, ensuring proper surface preparation and substrate conditions, conducting tests for geomembrane thickness and integrity, employing qualified and experienced installers, monitoring and documenting installation procedures, conducting seam testing and inspection, and performing post-installation inspections to ensure the geomembrane is properly installed and functioning as intended.

Q:How do geomembranes handle settlement?: Geomembranes are designed to handle settlement by being flexible and able to conform to the underlying surface. They can accommodate minor settlement without compromising their integrity, but for significant settlement, additional measures such as proper compaction and reinforcement may be needed to ensure their effectiveness.

Q:Can geomembranes be used in rainwater harvesting and storage systems?: Yes, geomembranes can be used in rainwater harvesting and storage systems. They are often used as liners in ponds, tanks, and reservoirs to prevent leakage and ensure the collected rainwater is properly stored. Geomembranes are impermeable and durable, making them an effective solution for rainwater storage applications.

Q:The difference between diamond films and diamond-like films where?: Diamond from ultraviolet to infrared spectrum has high optical transmittance, it is an excellent corrosion-resistant materials. two preparation of diamond films are thermal chemical vapor deposition (TCVD) and plasma chemical vapor deposition (PCVD). The study is to obtain diamond film as a wear-resistant coating, the acoustic diaphragm, optical window, integrated high thermal conductivity of the substrate. it Also studied epitaxial single-crystal diamond film on a silicon wafer to prepare a diamond devices. Diamond-like carbon (DLC) is an amorphous structure, mainly carbon atom sp3 and sp2 hybrid bond. Hydrogen-containing DLC ??is also called α-C: H, wherein a hydrogen content between 20% to 50%. Hydrogen-free DLC film includes hydrogen-free amorphous carbon (α-C) and tetrahedral amorphous carbon (ta-C) film. Α-C film contains some sp3 bonds; ta-C-based film mainly contains sp3 bonds (sp3 & gt; 70%).
