HDPE=Polyethylene kiʻekiʻe kiʻekiʻe, a i ʻole polyethylene kaomi haʻahaʻa.Aia ka nui ma luna o 0.940.
ʻO LDPE = polyethylene haʻahaʻa haʻahaʻa, a i ʻole polyethylene puʻe kiʻekiʻe, he polyethylene polymerized ma lalo o ke kaomi kiʻekiʻe, me ka mānoanoa ma lalo o 0.922.
ʻO ka geomembrane ʻeleʻele ka nui o HDPE (high density polyethylene) geomembrane, aʻo ka geomembrane keʻokeʻo ka nui o LDPE (low density polyethylene) geomembrane.ʻO ka ʻokoʻa ma waena o nā mea ʻelua ka nui o ka density a me ka hana.ʻOi aku ka nui o ka mānoanoa o ka mua, a ʻoi aku ka liʻiliʻi o ka puʻupuʻu o ka hope.Hoʻohana nui ʻia ka mea mua ma ke ʻano he geotechnical mea, aʻo ka mea hope e hoʻohana ʻia ma ke ʻano he kiʻiʻoniʻoni.
ʻO ke kumu i ʻeleʻele ai ka geomembrane ʻeleʻele i hana ʻia ka geomembrane me ka masterbatch ʻeleʻele, i hoʻohui ʻia i loko o ke kaʻina hana o ka geomembrane i ka like.ʻO ka mea maʻamau, hiki i kahi liʻiliʻi o ka masterbatch ke hana i ka nui o nā geomembranes, a ua maʻalahi nā ʻāpana masterbatch geomembrane i ka hana, ʻaʻole ia e pili i ka maikaʻi o ka geomembrane.
ʻO ka geomembrane keʻokeʻo no ka mea ua hoʻohui ʻia nā ʻāpana masterbatch keʻokeʻo i ka geomembrane, a ʻaʻole e hoʻopilikia nā ʻāpana masterbatch keʻokeʻo i ka maikaʻi o ka geomembrane.ʻOi aku ka kiʻekiʻe a me ka hana o ka geomembrane ʻeleʻele ma mua o ka geomembrane LDPE keʻokeʻo no ka mea ʻo ka hapa nui o lākou he HDPE geomembrane.Hoʻohana nui ʻia ka geomembrane LDPE keʻokeʻo e like me nā huahana plastic film, a hoʻohana nui ʻia.
No ka mea ʻoi aku ka nui o ka HDPE ʻeleʻele geomembrane ma mua o ka LDPE keʻokeʻo geomembrane, ʻokoʻa nā mea ʻelua.Pono e hoʻohālikelike ʻia ka maikaʻi holoʻokoʻa ma luna o ka hoʻohana ʻana o nā mea ʻelua i ke ʻano hana like.ʻAʻole pono ka hoʻohālikelike ʻana i ko lākou ikaika (incomparability).E hoʻohana ʻokoʻa nā mea ʻelua i ka hana ʻokoʻa, a i kekahi manawa e lilo lākou i pani no kekahi i kekahi.
ʻOi aku ka maikaʻi o ka geomembrane LDPE keʻokeʻo ma mua o ka geomembrane HDPE ʻeleʻele, a ʻoi aku ka ikaika o kona maʻalahi ma mua o ka geomembrane HDPE ʻeleʻele.ʻO ka geomembrane LDPE keʻokeʻo e kū ana i nā kikoʻī o ka hana ʻana he hanauna hou ia o nā mea geoimpermeable, a ʻoi aku ka ikaika o kona adaptability ma mua o ka HDPE geomembrane ʻeleʻele i ka papahana like.I kēia manawa, hiki i nā papahana he nui ke ʻike i ke aka o ka huahana.
Hiki ke ʻike ʻia ma luna aʻe nei he mau noi like ʻole ka HDPE geomembrane ʻeleʻele a me ka geomembrane LDPE keʻokeʻo i nā papahana like ʻole, ʻaʻole hiki ke hoʻonui ʻia.Loaʻa i nā ʻano huahana ʻelua ko lākou mau ikaika a me nā nāwaliwali.Pono e noʻonoʻo ʻia ka maikaʻi o kēia mau ʻano huahana ma muli o nā kūlana like ʻole.
