ʻO ka geomembrane ʻaʻahu
Wehewehe Pōkole:
Hana ʻia ka geomembrane ʻino i ka polyethylene kiʻekiʻe (HDPE) a i ʻole polypropylene ma ke ʻano he mea maka, a hoʻomaʻemaʻe ʻia e nā lako hana ʻoihana a me nā kaʻina hana kūikawā, me kahi ʻano ʻino a i ʻole nā puʻupuʻu ma ka ʻili.
Hana ʻia ka geomembrane ʻino i ka polyethylene kiʻekiʻe (HDPE) a i ʻole polypropylene ma ke ʻano he mea maka, a hoʻomaʻemaʻe ʻia e nā lako hana ʻoihana a me nā kaʻina hana kūikawā, me kahi ʻano ʻino a i ʻole nā puʻupuʻu ma ka ʻili.
Nā ʻano
ʻO ka geomembrane hoʻokahi-ʻano:He ʻoʻoleʻa ma kekahi ʻaoʻao a he laumania ma kekahi ʻaoʻao. I ke kūkulu ʻana i ka papahana pale i ka kahe ʻana o ka wai, ʻo ka ʻaoʻao ʻoʻoleʻa e kū pono ana i luna e hoʻopili aku me ka geotextile e hoʻokō ai i ka hopena pale i ka paheʻe.
Geomembrane pālua-ʻāwili:He ʻoʻoleʻa nā ʻaoʻao ʻelua. Ke hoʻohana ʻia, hiki i nā ʻaoʻao o luna a me lalo ke hoʻopili me ka geotextile no ka hana pale paheʻe, a hoʻohana nui ʻia.
Geomembrane kiko:Aia nā puʻupuʻu like ma kekahi a i ʻole nā ʻaoʻao ʻelua. Ua hoʻolaha like ʻia nā puʻupuʻu a nani ke nānā aku. Hiki ke hoʻopili ʻia i nā papahana anti-seepage pali e pāʻani i nā kuleana o ka anti-seepage, anti-slip a me ka anti-contamination.
Nā ʻano hana
Ka helu kuʻi kiʻekiʻe:Hiki i ke ʻano ʻinoʻino a i ʻole nā puʻupuʻu ma ka ʻili ke hoʻonui nui i ka friction me nā mea ʻē aʻe (e like me nā geotextiles, lepo, a pēlā aku), pale pono i ka geomembrane mai ka paheʻe ʻana ma nā pali kiʻekiʻe a i ʻole nā ʻili kū pololei, a hoʻomaikaʻi i ke kūpaʻa o ka papahana. He kūpono ia no nā papahana anti-seepage ma nā pali kiʻekiʻe e like me nā landfills a me nā pali dam.
Hana maikaʻi Anti-seepage:E like me nā geomembranes laumania, he haʻahaʻa loa kona coefficient permeability a hiki ke ālai pono i ke komo ʻana o ka wai, e pale ana i ka nalowale o ka wai a i ʻole ka hoʻolaha ʻana o ka haumia. Hiki ke hoʻohana ʻia i ka mālama wai, ka palekana o ke kaiapuni a me nā papahana ʻē aʻe me nā koi anti-seepage kiʻekiʻe.
Paʻa Kemika:He kūpaʻa kemika maikaʻi loa kona a hiki ke pale aku i ka pala o nā ʻano kemika waikawa ikaika a me ka alkali he 80 a ʻoi e like me nā waikawa, alkalis a me nā paʻakai. Hiki iā ia ke mālama i ka hana paʻa i nā papahana ʻenekinia me nā ʻano kemika like ʻole, e like me ka mālama ʻana i ka wai ʻino a me nā pahu hana kemika.
Hana Anti-kahiko:Loaʻa iā ia nā hiki ke kū'ē i ka ʻelemakule, kū'ē i ka ultraviolet a me ka decomposition maikaʻi loa a hiki ke hoʻohana ʻia me ka ʻike ʻole ʻia. Hiki i ke ola lawelawe o ka mea ke hiki i 50 - 70 mau makahiki, hiki ke hāʻawi i kahi hōʻoia hilinaʻi no nā papahana kū'ē i ka seepage lōʻihi.
Ikaika Mechanical Kiʻekiʻe:Loaʻa iā ia ka ikaika tensile kiʻekiʻe, ke kū'ē i ka haehae a me ke kū'ē i ka puncture, a me ka elasticity maikaʻi loa a me ka hiki ke hoʻololi. Hiki iā ia ke hoʻololi i ka hoʻonui ʻana a i ʻole ka emi ʻana o nā ʻili kumu a lanakila maikaʻi i ka noho ʻole ʻana o ka ʻili kumu.
Nā hiʻohiʻona noi
Nā Papahana Hoʻomalu Kaiapuni:I loko o nā ʻōpala hoʻolei ʻōpala, hoʻohana ʻia ia no ka pale ʻana i ke kahe ʻana o nā pali a puni a me ka lalo e pale aku i ka leaka ʻana o ka ʻōpala hoʻolei ʻōpala a me ka haumia ʻana i ka lepo a me ka wai honua. Hiki nō hoʻi ke hoʻohana ʻia no ka pale ʻana i ke kahe ʻana o nā loko hoʻolei puʻu a me nā uhi ʻōpala i ka ʻoihana mining e pale aku i ke kahe ʻana o nā mea ʻino.
Nā Papahana Mālama Wai:Hoʻohana ʻia ia no ka pali e pale aku ai i ka kahe ʻana o ka wai o nā waihona wai, nā pā wai, nā kahawai, a me nā mea ʻē aʻe, hiki ke pale i ka liki ʻana o ka wai. I kēia manawa, ma nā kūlana pali kiʻekiʻe, hiki i kāna hana anti-slip ke hōʻoia i ke kūpaʻa o ka geomembrane.
Nā Papahana Halihali:Hiki ke hoʻohana ʻia no ka pale ʻana i ke kahe ʻana o nā tunnels ma nā alaloa a me nā alahao, a no ka pale ʻana i nā pali subgrade me nā koi kūikawā anti-slip a me anti-seepage.
Nā Papahana Mahiʻai:Hoʻohana ʻia ia i loko o ka anti-seepage o nā pali a me nā lalo o nā loko aquaculture, hiki ke mālama i ka pae wai, pale i ka liki wai a me ka haumia lepo, a he kūpono hoʻi no ke kūkulu ʻana a me ka mālama ʻana i nā hale aquaculture.
