Geomembrane maʻemaʻe
ʻO ka wehewehe pōkole:
Hana ʻia ka geomembrane maʻemaʻe me kahi mea polymer hoʻokahi, e like me ka polyethylene (PE), polyvinyl chloride (PVC), a me nā mea ʻē aʻe.

Hana ʻia ka geomembrane maʻemaʻe me kahi mea polymer hoʻokahi, e like me ka polyethylene (PE), polyvinyl chloride (PVC), a me nā mea ʻē aʻe.

- ʻO ka hana anti-seepage maikaʻi: He haʻahaʻa loa ka permeability a hiki ke pale pono i ke komo ʻana o nā wai. Loaʻa iā ia ka hopena pale maikaʻi i ka wai, ka aila, nā hopena kemika, a me nā mea ʻē aʻe. Hiki i ka coefficient anti-seepage ke piʻi i 1 × 10⁻¹²cm/s i 1 × 10⁻¹⁷cm/s, hiki ke hoʻokō i nā koi anti-seepage o ka hapa nui o nā papahana. .
- Paʻa kemika ikaika: Loaʻa iā ia ka maikaʻi o ka waikawa a me ke kūpaʻa alkali a me ke kūpaʻa corrosion. Hiki iā ia ke kūpaʻa ma nā ʻano kemika like ʻole a ʻaʻole hiki ke hoʻopau ʻia e nā kemika o ka lepo. Hiki iā ia ke pale aku i ka ʻino o kekahi mau ʻano o ka waikawa, ka alkali, ka paʻakai a me nā hopena ʻē aʻe.
- ʻO ke kūpaʻa haʻahaʻa haʻahaʻa maikaʻi: Hiki iā ia ke mālama i ka loli maikaʻi a me nā waiwai mechanical i kahi haʻahaʻa haʻahaʻa. No ka laʻana, loaʻa i kekahi polyethylene smooth geomembranes kiʻekiʻe ka elasticity ma -60 ℃ a -70 ℃ a ʻaʻole maʻalahi i ka haki ʻana.
- Hana maʻalahi: He maʻalahi ka ʻili a he liʻiliʻi ka friction coefficient, kahi kūpono no ka waiho ʻana ma nā ʻāina like ʻole a me nā kumu. Hiki ke hoʻohui ʻia e ka welding, ka hoʻopaʻa ʻana a me nā ʻano hana ʻē aʻe. He wikiwiki ka wikiwiki o ke kūkulu ʻana a maʻalahi ka maikaʻi e hoʻokele.

- ʻO ke ʻano o ka hoʻoheheʻe ʻana i ka puhi ʻana: Hoʻomaʻamaʻa ʻia ka polimer maka i kahi kūlana hoʻoheheʻe ʻia a hoʻokuʻu ʻia ma o kahi extruder e hana i kahi tubular blank. A laila, puhi ʻia ka ea i hoʻopaʻa ʻia i loko o ka pahu blank no ka hoʻonui ʻana a hoʻopili i ka ʻeleʻele no ka hoʻoluʻu ʻana a me ke ʻano. ʻO ka hope, loaʻa ka geomembrane maʻemaʻe ma ka ʻoki ʻana. ʻO ka geomembrane i hana ʻia e kēia ʻano he ʻano mānoanoa like ʻole a me nā waiwai mechanical maikaʻi.
- Kaʻina Kalendering: Hoʻomaʻamaʻa ʻia ka polimer maka a laila hoʻokuʻu ʻia a hoʻohola ʻia e nā huila lehulehu o kahi kalena e hana i kahi kiʻiʻoniʻoni me kahi mānoanoa a me ka laulā. Ma hope o ka hoʻoluʻu, loaʻa ka geomembrane maʻemaʻe. Loaʻa i kēia kaʻina hana kiʻekiʻe a me ka laulā huahana ākea, akā ʻoi aku ka maikaʻi o ka mānoanoa like ʻole.
Nā kahua noi
- Papahana mālama wai: Hoʻohana ʻia ia no ka mālama anti-seepage o nā hale mālama wai e like me nā waihona, nā dams, a me nā canal. Hiki iā ia ke pale pono i ka leaka wai, hoʻomaikaʻi i ka mālama ʻana i ka wai a me ka maikaʻi o ka lawe ʻana i nā papahana mālama wai, a hoʻonui i ke ola lawelawe o ka papahana.
- ʻĀina: Ma ke ʻano he liner anti-seepage ma lalo a me ka ʻaoʻao o ka pae ʻāina, pale ia i ka leachate mai ka hoʻohaumia ʻana i ka lepo a me ka wai lepo a pale i ke kaiaola a puni.
- ʻO ke kūkulu ʻana i ka wai: Hoʻohana ʻia ia e like me ka papa wai i loko o ka hale, ka basement, ka hale ʻauʻau a me nā ʻāpana ʻē aʻe o ka hale e pale ai i ke komo ʻana o ka wai ua, ka wai lepo a me nā wai ʻē aʻe i loko o ka hale a hoʻomaikaʻi i ka hana wai ʻole o ka hale.
- ʻĀina hana: Hoʻohana ʻia ia no ka anti-seepage o nā loko kūlohelohe, nā loko ʻāina, nā papa wai kolepa, a me nā mea ʻē aʻe, e mālama i ke kūpaʻa o ke kino wai, e hōʻemi i ka nalowale o ka wai, a hāʻawi i kahi kumu maikaʻi no ka hoʻokumu ʻana i ka ʻāina.
Nā kikoʻī a me nā hōʻailona ʻenehana
- Nā kikoʻī: ʻO ka mānoanoa o ka geomembrane maʻemaʻe ma waena o 0.2mm a me 3.0mm, a ʻo ka laulā ma waena o 1m a me 8m, hiki ke hoʻopili ʻia e like me nā pono o nā papahana like ʻole.
- Nā hōʻailona ʻenehana: E komo pū me ka ikaika tensile, elongation ma ka haʻihaʻi, ka ikaika o ka haʻihaʻi ʻākau, ke kūpaʻa hydrostatic pressure, a me nā mea ʻē aʻe. ʻO ka ikaika ma waena o 50N / mm a me 300N / mm, a ʻo ke kūpaʻa hydrostatic ma waena o 0.5MPa a 3.0MPa.
