Geomembrane laumania
Wehewehe Pōkole:
ʻO ka geomembrane laumania ka mea maʻamau i hana ʻia me kahi mea polymer hoʻokahi, e like me ka polyethylene (PE), polyvinyl chloride (PVC), a me nā mea ʻē aʻe. He laumania a palahalaha kona ʻili, me ka ʻole o ke ʻano a i ʻole nā ʻāpana i ʻike ʻia.
ʻAno kumu
ʻO ka geomembrane laumania ka mea maʻamau i hana ʻia me kahi mea polymer hoʻokahi, e like me ka polyethylene (PE), polyvinyl chloride (PVC), a me nā mea ʻē aʻe. He laumania a palahalaha kona ʻili, me ka ʻole o ke ʻano a i ʻole nā ʻāpana i ʻike ʻia.
- Nā ʻano
- Hana maikaʻi anti-seepage: He haʻahaʻa loa kona permeability a hiki ke pale pono i ke komo ʻana o nā wai. Loaʻa iā ia kahi hopena pale maikaʻi e kūʻē i ka wai, ka ʻaila, nā hopena kemika, a me nā mea ʻē aʻe. Hiki i ke coefficient anti-seepage ke hiki i ka 1 × 10⁻¹²cm/s a i ka 1 × 10⁻¹⁷cm/s, hiki ke hoʻokō i nā koi anti-seepage o ka hapa nui o nā papahana.
- Paʻa ikaika kemika: Loaʻa iā ia ke kūpaʻa maikaʻi loa i ka waikawa a me ka alkali a me ke kūpaʻa i ka pala. Hiki iā ia ke noho paʻa i nā ʻano kemika like ʻole a ʻaʻole maʻalahi e palaho ʻia e nā kemika i loko o ka lepo. Hiki iā ia ke pale aku i ka pala o kekahi mau ʻano o ka waikawa, alkali, paʻakai a me nā hopena ʻē aʻe.
- Ke kūpaʻa haʻahaʻa maikaʻi: Hiki iā ia ke mālama i ka maʻalahi a me nā waiwai mechanical maikaʻi i kahi ʻano haʻahaʻa. No ka laʻana, ʻo kekahi mau geomembranes polyethylene laumania kiʻekiʻe e loaʻa mau ana kahi elasticity ma -60℃ a i -70℃ a ʻaʻole maʻalahi e haki.
- Kūkulu kūpono: He laumania ka ʻili a he liʻiliʻi ke koina friction, he kūpono ia no ke kau ʻana ma nā ʻano ʻāina like ʻole a me nā kumu. Hiki ke hoʻopili ʻia ma o ka wili ʻana, ka hoʻopaʻa ʻana a me nā ʻano hana ʻē aʻe. He wikiwiki ka wikiwiki o ke kūkulu ʻana a he maʻalahi ke kaohi i ka maikaʻi.
Kaʻina Hana
- ʻAno hana hoʻoheheʻe puhi extrusion: Hoʻomehana ʻia ka mea maka polymer i kahi mokuʻāina hoʻoheheʻe ʻia a hoʻopuka ʻia ma o kahi extruder e hana i kahi blank tubular. A laila, puhi ʻia ka ea i hoʻopaʻa ʻia i loko o ka blank tube e hoʻonui a hoʻopili i ka ʻōmole no ka hoʻomaʻalili a me ke ʻano. ʻO ka hope loa, loaʻa ka geomembrane laumania ma ka ʻoki ʻana. ʻO ka geomembrane i hana ʻia e kēia ʻano hana he mānoanoa like a me nā waiwai mechanical maikaʻi.
- ʻAno hana kalena: Hoʻomehana ʻia ka mea maka polymer a laila hoʻopuka ʻia a kīkoʻo ʻia e nā wili he nui o kahi kalena e hana i kahi kiʻiʻoniʻoni me kahi mānoanoa a me ka laulā. Ma hope o ka hoʻomaʻalili ʻana, loaʻa ka geomembrane laumania. Loaʻa i kēia kaʻina hana ka pono hana kiʻekiʻe a me ka laulā o ka huahana ākea, akā ʻaʻole like ka mānoanoa.
Nā Kahua Noi
- Papahana mālama wai: Hoʻohana ʻia no ka mālama ʻana i ke kahe ʻana o ka wai o nā hale mālama wai e like me nā waihona wai, nā pā wai, a me nā ʻauwai. Hiki iā ia ke pale pono i ka liki ʻana o ka wai, hoʻomaikaʻi i ka mālama wai a me ka pono o ka lawe ʻana i nā papahana mālama wai, a hoʻolōʻihi i ke ola lawelawe o ka papahana.
- ʻĀpana Hoʻolei ʻĀina: Ma ke ʻano he pale anti-seepage ma lalo a me ka ʻaoʻao o ka ʻāpana hoʻolei ʻāina, pale ia i ka leachate mai ka hoʻohaumia ʻana i ka lepo a me ka wai honua a pale i ke kaiapuni kaiaola a puni.
- Hale pale wai: Hoʻohana ʻia ia ma ke ʻano he papa pale wai ʻole ma ka hale, ka hale lua, ka lua ʻauʻau a me nā ʻāpana ʻē aʻe o ka hale e pale ai i ke komo ʻana o ka wai ua, ka wai honua a me nā makū ʻē aʻe i loko o ka hale a hoʻomaikaʻi i ka hana pale wai o ka hale.
- ʻĀina hana: Hoʻohana ʻia no ka pale ʻana i ka kahe ʻana o nā loko hana, nā loko ʻāina, nā ʻāina wai o ke kahua kolepa, a me nā mea ʻē aʻe, e mālama i ke kūpaʻa o ke kino wai, e hōʻemi i ka nalowale ʻana o ka wai, a hāʻawi i kahi kahua maikaʻi no ka hoʻokumu ʻana i ka ʻāina.
Nā Kikoʻī a me nā Hōʻailona ʻenehana
- Nā kikoʻī: ʻO ka mānoanoa o ka geomembrane laumania ma waena o 0.2mm a me 3.0mm, a ʻo ka laulā ma waena o 1m a me 8m, hiki ke hoʻopilikino ʻia e like me nā pono o nā papahana like ʻole.
- Nā ʻōkuhi loea: Me ka ikaika tensile, elongation i ka haki, ka ikaika haehae ʻākau-ʻākau, ke kūpaʻa hydrostatic pressure, a pēlā aku. ʻO ka ikaika tensile ma waena o 5MPa a me 30MPa, ʻo ka elongation i ka haki ma waena o 300% a me 1000%, ʻo ka ikaika haehae ʻākau-ʻākau ma waena o 50N/mm a me 300N/mm, a ʻo ke kūpaʻa hydrostatic pressure ma waena o 0.5MPa a me 3.0MPa.
