- Q: Is the notebook protective film good?
- It is best to prepare an adhesive tape and fold it in the shape as the figure below (used for sticking to dust). Before pasting, first shut down the power. You'd better post some soft cushion in the bottom of the screen, because the screen of most computers may not be able to fold to 180 degrees. It is best to fix the screen well. First clean the screen, and it must be cleaned thoroughly, otherwise there is dust left and small bubbles will appear. First take out the screen film to make sure that its size is the same with that of the screen. And after confirmation, you will see there are stickers marked 1 and 2 on the protective film. First fold the sticker marked 2 as the figure below. Then turn over the screen film. The side marked 1 should be adhered to the screen and it is ok to first uncover it a little bit.
- Q: What are the considerations for geomembrane selection in fish farming ponds?
- When selecting a geomembrane for fish farming ponds, several considerations need to be taken into account. Firstly, the geomembrane should be made from a material that is resistant to punctures and tears, as fish can potentially damage the liner. Secondly, the geomembrane must be able to withstand exposure to various chemicals and water treatments used in fish farming, without deteriorating or releasing harmful substances into the pond. Thirdly, UV resistance is crucial to prevent degradation from prolonged exposure to sunlight. Additionally, the geomembrane should have low permeability to prevent water seepage and maintain proper water levels. Lastly, the cost and ease of installation should also be considered to ensure the selection of a geomembrane that meets both technical requirements and budget constraints.
- Q: What is the electrical heating?film?
- The heating principle of the electrothermal?film The so-called?film heating material is a layer of conductive film formed on the surface of insulation material after being processed on the surface of the insulation material. The conductive particles form mesh-shaped lattice structure on the surface of the insulating layer, and the various additives added in the film can adjust the power of the electrothermal?film. After being electrified, this layer of film can achieve conversion, so people also call it electrothermal?film.
- Q: What functions does moistureproof membranes have?
- It prevents moisture and bug bites.
- 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 long does the film curing.
- Tack just one night, if you want to do quickly, spray a little thin.
- Q: How do geomembranes contribute to the preservation of archaeological sites?
- Geomembranes contribute to the preservation of archaeological sites by acting as a protective barrier against moisture, contaminants, and erosion. They are used to cover and line excavation areas, preventing the infiltration of water that can damage artifacts and structures. Geomembranes also help to stabilize the soil and prevent erosion, ensuring the structural integrity of the site. Additionally, they can be used to create controlled environments for the storage and preservation of delicate artifacts, allowing for long-term conservation.
- Q: What are the differences of geotextiles and geogrids?
- Geotextiles can be divided into two categories, namely the impervious geotextile and permeable geotextile. Geomembranes and impervious geotextiles can be used to prevent emission of ground water caused by capillarity. Geotextiles are porous to liquid but soil can't go through them. For example, they can be used on the surface of supporting sewers of high slopes.
- Q: How do geomembranes withstand UV exposure?
- Geomembranes are able to withstand UV exposure due to the addition of UV stabilizers during their manufacturing process. These stabilizers help to protect the geomembrane from the harmful effects of ultraviolet radiation, such as degradation and deterioration. This allows the geomembrane to maintain its structural integrity and performance over an extended period of time, even when exposed to sunlight.
- Q: What are the considerations for geomembrane installations in areas with high groundwater levels?
- When installing geomembranes in areas with high groundwater levels, several considerations need to be taken into account. Firstly, it is crucial to choose a geomembrane material that is impermeable to prevent the groundwater from seeping through. Additionally, proper site preparation is necessary, including leveling the ground, removing any sharp objects or debris that could puncture the geomembrane, and ensuring a stable foundation. Adequate drainage systems should be installed to prevent water buildup between the geomembrane and the subgrade. The installation process should also involve careful welding or seaming of the geomembrane to ensure its integrity and prevent leaks. Regular inspections and maintenance are essential to identify and address any potential issues promptly. Overall, thorough planning, material selection, and proper installation techniques are vital when dealing with high groundwater levels in geomembrane installations.
