FAQ

What is the difference between nonwovens and geomembranes in hydraulic engineering?

Non-woven and geomembrane, geosynthetics are two kinds of materials. From the appearance of: non-woven is a porous material permeable material. Geomembrane is generally dense and dense material. From their function to distinguish: non-woven mainly used to filter, isolation, high strength can also be used to strengthen, but with less, because the economy is irrational. Geomembrane, impermeable waterproof is its main function.

Yes, geomembranes can be used in irrigation reservoirs. These synthetic liners are commonly used to prevent seepage and leakage in water containment systems, including irrigation reservoirs. They provide an effective barrier to retain water and prevent it from infiltrating into the surrounding soil. Additionally, geomembranes also help in reducing water loss through evaporation, which can be beneficial in water-scarce regions.

The purpose of a geomembrane liner is to provide a barrier and containment system for various applications such as preventing the leakage or seepage of liquids, gases, or contaminants in structures like landfills, ponds, reservoirs, and mining sites. It acts as a protective layer, ensuring environmental and public safety by preventing pollution, preserving water quality, and minimizing the risk of leaks or damages.

base film is an alternative to a new generation of products, before the wallpaper brush again played a major role in the base film is to protect your walls to prevent water, basic substances within the walls of extravasation, but also more effectively wallpaper adhere to the wall, in the future when more simple and convenient replacement of wallpaper, which is a water-based environmentally friendly materials, tasteless, non-toxic, no side effects on the human body, and now the wallpaper has to be brushed before pasting.

Uv matt lamination gloss oil, a synthetic resin, usually refers to the varnish with transparent surface. It is made of binder and additives without any pigment, and it glisten after filming. It is also known as matt lamination varnish. Function 1. Transparent protective lacquer whose hardness and wear-resistant properties are better than colored paint, which can play a protective role. 2, Hand feeling paint has good luminosity and brightness, and it feels good.

detect all the welding lines with aerate methods, wrinkles or not, cracks, deterioration or degradation of other materials .5min, construction quality inspection mainly depends on sampling .20MPa.05MPa ~ 0, under construction, we should choose a test?specimen out of every 1000m2, the focus of geomembrane construction quality control include the quality control of importing raw materials, holes, qualified welding line and gas needle. 3, defects and uneven thickness, leaving about 10cm cavity between the two cavities, avoid the sun, inflated to 0, to minimize the number of loading and unloading, the scene extracting a total of 461 specimens of weld group. 1. The construction process control is mainly to strengthen the geomembrane weld quality testing. 2. (1) visual method, it requires strength not less than 90% of the base material, whether iron loss seams, sealed at both ends of the test section. The whole project uses a total of geomembrane approximately 461100m2. (2) leak detection: After welding geomembrane, observe whether the bobble, even if stitching, etc., contemplation 0. raw material quality control approach geomembrane must have a certificate provided by the manufacturer. Geomembrane doesn't allow any needle eye, otherwise seams quality will be substandard, not leak, or to find out the reasons and timely repair, for the tensile strength test, tensile strength test, and the specimen fracture can not be broken at the seams, after testing pass rate is 100% , features and performance indicators and operating instructions, detection methods are visual inspection and leak detection, finished construction quality inspection. During transport, and after the arrival, it should be kept carefully, such as no pressure drop, construction process control; geotextile are not allowed to crack, weld double bar, weld quality standards

Geomembranes are used as a barrier to prevent soil erosion by providing a durable and impermeable layer. They are designed to withstand the erosive forces of water, wind, and other environmental factors, thereby protecting the soil beneath from being washed away or displaced. Additionally, geomembranes can be anchored or secured in place to further enhance their effectiveness in preventing soil erosion.
