ʻO ka Linear Low Density Polyethylene (LLDPE) Geomembrane
Wehewehe Pōkole:
ʻO ka geomembrane linear low-density polyethylene (LLDPE) kahi mea polymer anti-seepage i hana ʻia me ka resin linear low-density polyethylene (LLDPE) ma ke ʻano he mea maka nui ma o ka hoʻoheheʻe ʻana i ka puhi ʻana, ka ʻili hoʻolei a me nā kaʻina hana ʻē aʻe. Hoʻohui ia i kekahi o nā ʻano o ka polyethylene kiʻekiʻe-density (HDPE) a me ka polyethylene haʻahaʻa-density (LDPE), a he mau pono kūikawā i ka maʻalahi, ke kū'ē ʻana i ka puncture a me ka hiki ke hoʻololi i ke kūkulu ʻana.

Nā ʻano hana
Ke kūpaʻa maikaʻi loa i ka seepage
Me kahi ʻano molekala paʻa a me ka coefficient permeability haʻahaʻa, hiki i ka geomembrane LLDPE ke pale pono i ka liki ʻana o ka wai. ʻO kona hopena seepage-proof ua like ia me ko ka geomembrane HDPE, e hoʻohana nui ʻia i nā papahana e pono ai ka kaohi seepage.
Ka Maʻalahi Maikaʻi
Hōʻike ia i ka maʻalahi o ka loli a ʻaʻole maʻalahi ka palupalu i nā mahana haʻahaʻa, me kahi pae kūpaʻa mahana ma kahi o - 70°C a 80°C. ʻAe kēia iā ia e hoʻololi i nā ʻāina ʻokoʻa a i ʻole nā wahi me ke kaumaha ikaika, e like me nā papahana mālama wai ma nā wahi mauna me nā ʻāina paʻakikī.
Ke kū'ē ikaika i ka puncture
He paʻa loa ka membrane, a ʻoi aku ka maikaʻi o kona kūpaʻa i ka haehae a me ka hopena ma mua o nā membrane laumania HDPE. I ka wā o ke kūkulu ʻana, hiki iā ia ke pale aku i nā puka mai nā pōhaku a i ʻole nā mea ʻoi, e hōʻemi ana i ka pōʻino ulia pōpilikia a hoʻomaikaʻi i ka hilinaʻi o ka papahana.
Ka Hoʻololi Kūpono i ke Kūkulu ʻana
Hiki ke hoʻopili ʻia ma o ka wili wela-hoʻoheheʻe ʻia, a kiʻekiʻe ka ikaika o ke hui ʻana, e hōʻoiaʻiʻo ana i ka pono o ka pale ʻana i ke kahe ʻana. I ka manawa like, ʻo kona ductility maikaʻi e maʻalahi ai ke kūlou a me ke kīkoʻo i ka wā o ke kūkulu ʻana, a hiki iā ia ke kūpono i nā kumu paʻakikī e like me nā kino lepo ʻaʻole like a me nā pali lua kumu, e hōʻemi ana i ka paʻakikī o ke kūkulu ʻana.
Kū'ē maikaʻi i ka palaho kemika
Loaʻa iā ia kahi hiki ke pale aku i ka pala o nā hopena waikawa, alkali, a me ka paʻakai, a kūpono ia no ka hapa nui o nā hiʻohiʻona pale wai maʻamau. Hiki iā ia ke kū i ka pala ʻana o nā mea kemika like ʻole i kekahi ʻano a hoʻolōʻihi i ke ola lawelawe.
Nā Kahua Noi
Nā Papahana Mālama Wai
He kūpono ia no nā papahana pale wai o nā waihona wai liʻiliʻi a me waena, nā kahawai, a me nā pahu mālama, ʻoi aku hoʻi ma nā wahi me nā ʻāina paʻakikī a i ʻole ka noho ʻana like ʻole, e like me ke kūkulu ʻana i nā pā wai ma ka Loess Plateau, kahi e hiki ai ke hoʻohana ʻia kona maʻalahi a me ka hana pale wai. No nā papahana mālama wai no ka manawa pōkole a i ʻole ke kau, e like me nā pahu mālama wai pilikia maloʻo, ʻo kona mau pono o ke kūkulu maʻalahi a me ke kumukūʻai haʻahaʻa e lilo ia i koho kūpono.
Nā Papahana Hoʻomalu Kaiapuni
Hiki ke hoʻohana ʻia ma ke ʻano he papa pale wai no ka manawa pōkole no nā ʻōpala liʻiliʻi, pale wai no ka hoʻoponopono ʻana i nā loko wai, a me nā uhi no nā loko wai ʻino ʻoihana (i nā kūlana ʻaʻole ikaika ka ʻino), e kōkua ana i ka pale ʻana i ka liki ʻana o nā mea haumia a pale i ke kaiapuni a puni.
ʻO ka mahiʻai a me ka mahiʻai wai
Hoʻohana nui ʻia ia i ka pale ʻana i ke kahe ʻana o ka wai i loko o nā loko iʻa a me nā loko ʻōpae, hiki ke pale pono i ka liki ʻana o ka wai a hoʻomaikaʻi i ka hoʻohana pono ʻana i nā kumuwaiwai wai. Hiki nō hoʻi ke hoʻohana ʻia no ka pale ʻana i ke kahe ʻana o ka wai i loko o nā pahu mālama wai mahiʻai, nā mea hoʻoheheʻe biogas, a me ka hoʻokaʻawale ʻana i ka makū a me ke aʻa ma lalo o nā hale ʻōmaʻomaʻo, a hiki ke hoʻololi i ka deformation iki o ka lepo ma muli o kona palupalu.
ʻEnekinia Halihali a me ke Kaona
Hiki ke hoʻohana ʻia ma ke ʻano he papa pale wai no nā alanui, e pani ana i nā papa ʻiliʻili kuʻuna a e hōʻemi ana i nā kumukūʻai papahana. Hiki nō hoʻi ke hoʻohana ʻia no ka hoʻokaʻawale ʻana i nā ʻauwaha paipu ma lalo o ka honua a me nā tunnels uwea e pale ai i nā hale ma lalo o ka honua mai ka ʻino ʻana o ka wai.
