ʻO kahi HDPE geomembrane maʻemaʻe he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa synthetic membrane liner a i ʻole pale me ka ʻili maʻemaʻe. Hiki ke hoʻohana wale ʻia a i ʻole me kekahi mea pili i ka ʻenekinia geotechnical i mea e hoʻomalu ai i ka neʻe ʻana o ka wai (a i ʻole ke kinoea) i loko o kahi papahana i hana ʻia e ke kanaka, hale, a ʻōnaehana paha. Hoʻomaka ka hana ʻana o ka HDPE geomembrane maʻemaʻe me ka hana ʻana i nā mea maka, ʻo ia ka nui o ka HDPE polymer resin, a me nā mea hoʻohui like ʻole e like me ka carbon black, antioxidants, anti-aging agent, UV absorber, a me nā mea kōkua ʻē aʻe. ʻO ka lākiō HDPE resin a me nā mea hoʻohui he 97.5: 2.5.
