Product Description
HDPE Smooth Surface Geomembrane
Product Introduction：
HDPE smooth geomembrane is produced by 95% of the original resin heating stabilizer and antioxidantthrough blow molding process or calendering process, which has the effect of impermeability and isolation.
Function And Use：
Environmental protection projects: landfills, sewage treatment plants, chemical wastewater tanks, power plant regulating tanks, industrial and medical waste landfills, ash and slag sites, and evaporation pond anti-seepage.Petrochemical: oil storage tanks in petrochemical refineries, oil well sludge tanks, chemical reaction tanks, sedimentation tanks, tailings dam bottom linings, and secondary lining anti-seepage.Chemical mining: ash and slag sites, red mud piles, heap leaching ponds, dissolution ponds, sedimentation tanks, and tailings dam bottom lining anti-seepage.Aquaculture: lining of aquaculture ponds, fish ponds, shrimp ponds, sea cucumber ponds, slope protection, and other anti-seepage works.Construction projects: subways, underground garages, roof gardens, sewage pipelines, drainage water tanks, and culvert anti-seepage.Agriculture, forestry and animal husbandry: anti-seepage of reservoirs, cisterns, drinking water tanks and irrigation systems.Salt chemical industry: salt plant crystallization tanks, bittern brine tanks, salt films, and other anti-seepage works.
