    Several types of composite geomembrane and construction techniques

    Composite geomembrane is a member of a large family of geosynthetic materials. It is widely used in highways, railways, water conservancy, large buildings, power plant ash dam construction, non-ferrous metal tailings treatment, environmental protection engineering, water and soil conservation, etc. The service life of the composite geomembrane is mainly determined by whether the plastic film loses its anti-seepage and water-blocking effect. According to the national standards, a 0.2cm thick polyethylene film with stabilizer for hydraulic engineering is used under clean water conditions. The working period can reach 40~50 years, and the working period under sewage conditions is 30~40 years. Therefore, the service life of composite geomembrane is enough to meet the service life of dam anti-seepage requirements.

    Uncover the anti-seepage secret of Vulcan Mountain Raytheon Mountain Hospital: "Two Geotextile and One Geomembrane" construction process, find out!

    Although the Vulcan and Raytheon hospitals were built as temporary hospitals to fight the epidemic, they are not “temporary” at all in wastewater treatment: fully enclosed operation, and pumped to the municipal pipe network after the third-level liquid chlorine disinfection; press under the entire base HDPE geomembrane is laid as standard in the landfill, as if wearing "protective clothing", the rainwater is collected and disinfected completely, and no drop of sewage is allowed to enter the ground!

    HDPE Geomembrane composite geotextile

    The composite geomembrane is heated by far-infrared heating on one or both sides of the film, and the geotextile and the geomembrane are pressed together by a guide roll to form a composite geomembrane. With the improvement of the production process, there is also a casting process for composite geomembrane. The form has a geotextile one geomembrane, two geotextiles one geomembrane, two geomembrane one geotextile and the like.

    The difference between needle punched geotextile and meltblown textile

    1. Needle-punched geotextiles, needle-punched geotextiles are divided into continuous filament needle punched geotextile and staple fiber needle-punched geotextiles. 2. Meltblown textile, melt-blown non-woven process uses high-speed hot air to draw a thin stream of polymer melt extruded from the spinneret of the die, thereby forming ultrafine fibers and condensing on the curtain net, Rely on self-adhesion to become a nonwoven.
