Geomembrane The geomembrane of the chemical impermeable pool has a good chemical stability function, can resist the corrosion of strong acids, alkalis and oils, and is good to add antioxidant and anti-corrosion molecules with excellent virgin polyethylene particles and carbon black particles. The main effect is to act as a barrier. When laying, the expansion and contraction deformation caused by temperature changes should be reserved according to the local temperature change amplitude and the performance requirements of HDPE geomembrane, and the expansion and contraction amount of geomembrane should be reserved according to the site topography and geomembrane laying to adapt to the uneven settlement of the foundation.
The use of HDPE impermeable geomembrane in animal husbandry farm engineering should ensure the safe operation of the building, the geomembrane can meet the requirements of low temperature resistance and anti-brittleness without disturbance, the impermeable membrane of the farm is made of one or several polymers plus carbon black, pigments and other additives made of impermeable materials, it is one of the three major materials used in the construction of landfills and artificial lakes in recent years (there are geonets and geotextiles), and its impermeability is the main index to measure whether the sanitary landfill meets the requirements.
Pig farm high-density poly (HDPE) geomembrane is a geomembrane applied in landfills, which is made of polymer poly through blow molding or flat extrusion, and the geomembrane is 2 mm thick geomembrane with fine technology and strong durability impermeable material.
Cattle farm geomembrane function use: landfill, sewage or waste residue treatment site seepage prevention. River embankments, lake dams, tailings dams, sewage dams and reservoir areas, channels, reservoirs (pits, mines), subways, basements, tunnels, tunnel seepage lining. In addition, when the water level in the reservoir drops sharply, the water level of the soil in the reservoir will also be reduced, which will cause excess void water pressure in the soil body, and may also cause the material to tear due to the unstable factors in the anti-seepage architecture. Marine and freshwater aquaculture farms. Highway, ** geomembrane 12 mm thick geomembrane fine process highway and railway foundation;Waterproofing layer of expansive soil and collapsible loess, impermeable roofing.
The impermeable membrane is used in industrial and mining enterprises sewage pool seepage, waste water pool seepage prevention, chemical reaction pool seepage prevention, acid and alkali tank seepage prevention, sludge tank seepage prevention, sedimentation tank seepage prevention, toxic liquid collection tank seepage prevention, power plant regulating pool waterproof, seepage prevention and anti-corrosion and other environmental protection projects.

HDPE impermeable membrane is widely used in municipal engineering, and also widely used in wastewater treatment engineering, the process is a waterproof two-layer structure, and its membrane is composed of HDPE membrane barrier strip, HDPE geotechnical waterproof membrane and geotextile.
