Waterproof Geomembrane/Liner/ Sheet with China Top Quality

Q: What are the common applications for geomembranes?: Geomembranes are commonly used in a wide range of applications such as waste containment, mining, agriculture, water management, and civil engineering projects. These synthetic liners provide an impermeable barrier, effectively preventing the leakage of liquids or gases, and are particularly useful in protecting the environment and ensuring the integrity of various structures.

Q: Are HDPE waterproof roll, HDPE anti-seepage film and HDPE geomembrane the same?: HDPE anti-seepage film uses resin of polyethylene. The high density polyethylene is about 2.5%. Carbon black, inhibitor, antioxygen, ultraviolet light absorber, stabilizer and other auxiliary materials are made through three-layer co-extrusion technology. HDPE geomembrane is made from 97.5% high-quality polyethylene, 2.5% carbon black, microscale antioxygen and heat stabilizer through special co-extrusion technology.

Q: Need we stick membrane on SLR camera?: There is no need to stick membrane on the lens of the camera. The surface of lens itself has coating which can be corroded by the membrane stuck by ourselves. To protect the lens from scratching and touching, it's recommended to buy an ultraviolet filter with multilayer coating which can resist ultraviolet light and prevent the amount of light from dropping at the same time.

Q: What is the sunshade screen protector: It is composed of surface protective layer, plastic film substrate, holographic etching layer, metal deposition layer, pressure sensitive adhesive layer and anti adhesion layer. Therefore, the sun shading film has a basic function, such as excellent visible light and ultraviolet ray shielding rate, at the same time, it also has the function of preventing fog and the fine appearance based on holographic effect.

Q: Can geomembranes be used in fish hatcheries?: Yes, geomembranes can be used in fish hatcheries. Geomembranes are impermeable liners that can effectively contain water, making them suitable for creating fish ponds, tanks, or raceways in fish hatcheries. They help to prevent water leakage, maintain water quality, and provide a controlled environment for fish rearing and breeding.

Q: Can geomembranes be used in geotechnical applications?: Yes, geomembranes can be used in geotechnical applications. Geomembranes are impermeable sheets made of synthetic materials that can be used to control seepage, contain liquids or gases, and provide stability in various geotechnical projects such as landfills, dams, tunnels, and soil stabilization. They are highly effective in preventing groundwater contamination and ensuring the structural integrity of these geotechnical structures.

Q: What are the properties of decorative film?: The film can insulate heat and ultraviolet ray and is anti-explosion, anti-theft, bullet-proof. When the glass is crushed by external shocks, the flying pieces are extremely easy to harm people.

Q: How do geomembranes contribute to erosion control in bridge and culvert construction?: Geomembranes contribute to erosion control in bridge and culvert construction by providing a protective barrier that prevents water from infiltrating the soil and causing erosion. They act as a waterproof lining, effectively reducing the flow of water and preventing it from eroding the surrounding soil. This helps to maintain the structural integrity of bridges and culverts, ensuring their long-term stability and reducing the need for costly repairs or replacements.

Q: Can geomembranes be used in decorative applications?: Yes, geomembranes can be used in decorative applications. They can be customized in various colors and patterns to enhance the aesthetic appeal of spaces such as gardens, ponds, and even rooftops. Additionally, geomembranes provide durability and weather resistance, making them a practical choice for decorative purposes.
