ʻO Geomembrane kahi mea wai a me ka mea pale e pili ana i nā polymers kaumaha molekala kiʻekiʻe. Hoʻokaʻawale ʻia ia i nā geomembranes haʻahaʻa haʻahaʻa polyethylene (LDPE), nā geomembranes polyethylene kiʻekiʻe (HDPE), a me nā geomembranes EVA. He ʻokoʻa ka geomembrane hui pū ʻia me nā geomembrane maʻamau. ʻO kona hiʻohiʻona, ʻaʻole i ʻope ka hui ʻana o nā laina longitude a me ka latitu, a aia kēlā me kēia ma ke ʻano pololei. Me ka hoʻohana ʻana i ke kaula wili e hoʻopaʻa paʻa i nā mea ʻelua hiki ke hoʻokō i ka hoʻonohonoho like ʻana, kū i nā ikaika o waho, puʻunaue i ke koʻikoʻi, a i ka wā i hoʻohana ʻia ai ka ikaika o waho e haehae i ka mea, e hōʻuluʻulu ka yarn ma ka māwae mua, e hoʻonui ai i ka waimaka. I ka wā o ka hui hili ʻana, hoʻohele pinepine ʻia ke kaula wili ma waena o ka lau, weft, a me nā papa fiber o ka geomembrane e ulana i nā ʻekolu i hoʻokahi. No laila, ʻaʻole wale nā ​​hiʻohiʻona o ka ikaika tensile kiʻekiʻe a me ka elongation haʻahaʻa, akā loaʻa pū kekahi i ka hana wai o nā geomembranes. No laila, ʻo ka warp knitted composite geomembrane he mea anti-seepage i loaʻa nā hana o ka hoʻoikaika, kaʻawale, a me ka pale. He noi kiʻekiʻe loa ia o nā mea hoʻohui geosynthetic ma ka honua i kēia lā.

ʻO ka ikaika tensile kiʻekiʻe, ka elongation haʻahaʻa, ka lōʻihi o ka lōʻihi a me ka transverse deformation, ke kūpaʻa waimaka kiʻekiʻe, ke kūpaʻa maikaʻi loa, a me ke kūpaʻa wai ikaika. lole lole. ʻO kāna hana anti-seepage ma muli o ka hana anti-seepage o ke kiʻiʻoniʻoni plastik. ʻO nā kiʻiʻoniʻoni plastik i hoʻohana ʻia no nā noi anti-seepage ma ka home a me ka honua ka nui o (PVC) polyethylene (PE) a me ka ethylene/vinyl acetate copolymer (EVA). He ʻano ia o ka polymer chemical flexible material me kahi umekaumaha kikoʻī liʻiliʻi, hiki ke hoʻonui i ka ikaika, hiki ke hoʻololi kiʻekiʻe i ka deformation, kūpaʻa corrosion, kūpaʻa haʻahaʻa haʻahaʻa, a me ke kūpaʻa hau maikaʻi. Hoʻoholo nui ʻia ke ola lawelawe o nā geomembranes composite ma muli o ka nalowale ʻana o ke kiʻi ʻoniʻoni i kona mau waiwai anti-seepage a me ka wai. Wahi a nā kūlana aupuni Soviet, hiki i nā kiʻiʻoniʻoni polyethylene me ka mānoanoa o 0.2m a me nā stabilizer i hoʻohana ʻia i ka ʻenekinia wai hiki ke hana no 40-50 mau makahiki ma lalo o nā kūlana wai maʻemaʻe a me 30-40 mau makahiki ma lalo o nā kūlana wai. No laila, lawa ke ola lawelawe o ka geomembrane composite e hoʻokō i nā koi anti-seepage o ka dam.
