For example, when the temperature drops suddenly or is suddenly cooled by rain after exposure, the plate tightening becomes poor and the beam is poorly lagging, so that the plate is cracked due to the limited tensile stress of the beam when the plate is tightened. The poorer the plate length, the easier it is to dequeue Penetrating flaws perpendicular to the long side of the board. The raw materials used for 3D geonet for sale should not only consider the physical and chemical properties required in the environment of use, but also pay attention to product costs. In terms of performance, the following aspects are mainly considered:

UV radiation resistance, hydrolysis resistance, high and low temperature resistance: Geotextiles must be exposed to sunlight, so they must have corresponding UV resistance; geotextiles must adapt to the temperature when contacting with asphalt and other materials, and require a higher melting point.

Chemical resistance, corrosion resistance, mildew resistance: water and soil quality are very different, some are alkaline, some are acidic, some are salty, and some contain various elements, so the plastic geonet manufacturers must be chemically stable Sex.

Good water permeability: Both geotextile filtration and drainage need water permeability, so it must have good water permeability.

Good physical and mechanical properties: the working environment of the HDPE geonet manufacturers is bad, in many cases it is soaked in water or spread in soil with high humidity, so it must have good resistance to hydrolysis and wet mechanical properties.

Geotextile uses plastic film as the impermeable base material and non-woven fabric composite impermeable material. Its impermeable function mainly depends on the impervious function of the plastic film. The primary mechanism of high quality HDPE geonet is therefore the impermeability of the plastic film to isolate the leakage path of the earth dam, with its poor tensile strength and extension rate, it is subjected to water pressure and conforms to the deformation of the dam body; Welding, base debris, etc. are being carefully checked, and all construction employees should implement this occupation in the overall construction process.
