The most widely used among landfill impermeable?materials is HDPE geomembrane, more than 90% of the world's landfills are using high-density polyethylene geomembrane as impermeable materials. Among HDPE geomembranes, the imported products are superior, because geomembrane :1 good chemical stability, landfill leachate will not pose a threat to them; 2 low permeability, underground?water and rainwater dialysate will not permeate through the liner, and methane gas will not come out; 3 carbon black in HDPE enhanced UV resistance, which is plasticizer-free, solving decomposition exposed to ultraviolet light. So HDPE geomembrane landfill is the preferred choice of impermeable materials, and is also the most commonly used.
Good physical?and?mechanical?properties, high tear strength, strong deformation adaptability, puncture-resistance, anti-aging, UV resistance, oil, salt, acid-base, and corrosion resistance, high and low temperature resistance, non-toxic, as well as long service life. Water proof, good performance in drainage, seepage-proof, and moisture-proof, complete specifications in width, and thickness , low cost, simple construction. You can search Texas Rui geotextile in Materials Engineering Co., Ltd. on Baidu, their geomembrane is good, and the price is very cheap.
It is durable and the key is that it needs a short construction period and it is inexpensive.
Properties of HDPE geomembrane: ① excellent chemical resistance (corrosion resistance); ② outstanding ability of stress cracking resistance(ESCR); ③ low permeability; ④ excellent UV resistance; ⑤ stable low temperature vertical performance; The above is taken from Baidu Encyclopedia, there is another reason, the price is relatively more economical.
