Waterproof Geomembrane/Liner/ Sheet with China Top Quality

Q: Does anyone know the mechanism of ion exchange membrane: Ion exchange resins are high molecular material with an ion exchange function. in the solution, the ion of itself will have an exchange with the ion which has the same symbol in the solution. According to the nature of different exchange groups, the ion exchange resins can be classified into two categories cation exchange resin and anion exchange resin, most of the cation exchange resin have a sulfonic acid group (-SO3H), carboxyl (-COOH) or phenol (-C6H4OH), etc. and other acidic group, wherein the hydrogen ions can have a exchange with a metal ion in solution or other cation ion, anion exchange resin containing quaternary amine [-N (CH3) 3OH], amino (-NH2 ) or imino (-NH2 ) and other alkali basic group. They can generate OH- ions in water, which can have the exchange interaction with various anions, and the ion exchange resin is in very widely use, it is mainly used for the isolation and purification.

Q: What is the HS mode of HDPE geomembrane?: 1 3920109010 agricultural non-foamed polyethylene thin film, 2 3920109090 other non-foamed ethylene polymer plates, sheets, film, foil and flat strip(non-agricultural).

Q: Can geomembrane HDPE replace waterproof roll modified asphalt sbs to be used in architecture?: Does not meet the SBS construction conditions SBS can not conduct construction on the waste plant, because the base under the waste plant is soil layer; flat

Q: What are the considerations for geomembrane installations in high-wind areas?: When installing geomembranes in high-wind areas, several considerations need to be taken into account. Firstly, the selection of a suitable geomembrane material with a high tensile strength and resistance to tearing is crucial. The installation techniques should also be tailored to withstand strong winds, which may involve using additional anchoring methods, such as ballasting or mechanical fastening, to ensure the geomembrane remains securely in place. Furthermore, the design of the geomembrane system should consider wind load calculations, taking into consideration factors such as wind direction, duration, and gustiness. Regular inspections and maintenance should be conducted to identify and address any potential wind-related damage or stress on the geomembrane. Overall, a comprehensive understanding of the site-specific wind conditions and the appropriate design and installation measures are essential for a successful geomembrane installation in high-wind areas.

Q: How do geomembranes improve water efficiency in golf course irrigation?: Geomembranes improve water efficiency in golf course irrigation by acting as a barrier that prevents water from seeping into the ground and instead directs it towards the desired areas. This helps to minimize water loss through evaporation and deep percolation, ensuring that the water is effectively utilized for irrigation purposes. Additionally, geomembranes can also help in managing water runoff and preventing soil erosion, further enhancing water efficiency on golf courses.

Q: What are the main usages and applications of high density polyethylene film (HDPE) in refuse landfill?: At the same time it can be used for the middle cover, fly eradication and deodorization. HDPE geomembrane is the core of urban household refuse landfill anti-seepage materials.

Q: What are the advantages of using geomembranes in aquaculture facilities?: There are several advantages of using geomembranes in aquaculture facilities. First, geomembranes provide an impermeable barrier that helps to prevent water leakage, ensuring efficient water management and reducing the risk of contamination. Additionally, geomembranes help to maintain optimal water quality by preventing the intrusion of unwanted substances such as pollutants or parasites. Moreover, these membranes help in reducing maintenance costs by preventing the growth of algae or other organisms on the facility's surfaces. Lastly, geomembranes improve the overall durability and longevity of aquaculture facilities, ensuring a sustainable and reliable environment for fish and other aquatic organisms.

Q: Does geomembrane has the color of grey?: The color of the geomembrane is mostly black, and also green, white, gray, black green and other colors. The main material of geomembrane is high density polyethylene, auxiliary materials are antioxidants, anti UV agent, carbon black, masterbatch and so on, color of the geomembrane depending on the colour of added masterbatch. There is also geomembrane without auxiliary material, and it is transparent.

Q: How to tear down polarizing film from display?: The steps of polarizer replacement: 1. Tear down the old polarizer. Problems: It requires specialized equipment, because it needs large and even force, and it can not be completed by hands. 2. adhesive?residue cleaning of glass surface. Problems: It needs professional cleanser, and the adhesive residue must be clean up. 3. Stick the new polarizing plate.

Q: How are geomembranes used in geotechnical engineering?: Geomembranes are used in geotechnical engineering as a lining or barrier system to control the flow of liquids, gases, or contaminants in various construction projects such as landfills, ponds, reservoirs, and tunnels. They provide an impermeable barrier that prevents seepage and leakage, ensuring environmental protection and structural stability.
