Nā hiʻohiʻona noi no Geomembranes

I loko o kahi au e kū nei nā papahana ʻoihana a me nā papahana palekana kaiapuni i nā koi koʻikoʻi no ka impermeability, lawelawe nā geomembranes ma ke ʻano he "mea nui no ka kaohi ʻana i ka seepage"; ʻo kā lākou hana a me ke kūpono e hoʻoholo pololei i ka palekana a me nā pono ecological o kahi papahana. Ma ka hoʻohana ʻana i nā makahiki o ka ʻike loea i hōʻiliʻili ʻia a me ka R&D kikoʻī, ua ʻike ʻo Shandong Hongyue Environmental Engineering Co., Ltd. i kāna mau huahana geomembrane i hoʻohana nui ʻia ma mua o ka ʻumikūmālua mau ʻāpana - me ka mālama wai, ka palekana kaiapuni, ka halihali, a me ka mahiʻai. ʻIke ʻia e ko lākou "impermeability kiʻekiʻe, ke kūpaʻa ikaika o ka wā, a me ka maʻalahi o ke kau ʻana," kūkulu maikaʻi kēia mau huahana i kahi "laina pale honua" paʻa no nā ʻano papahana ʻenekinia like ʻole.
ʻO ka laina huahana geomembrane a Shandong Hongyue Environmental e kālele ana ma luna o nā geomembranes HDPE (High-Density Polyethylene), e hoʻopuni ana i nā ʻano like ʻole e like me nā membrane laumania, textured, a me nā composite. Me ka laulā mānoanoa o 0.2 mm a 3.0 mm, ua kūlike kēia mau huahana me ke kūlana aupuni GB/T17643-2011. ʻO ko lākou coefficient impermeability hiki i ka 1 × 10⁻¹² cm/s—like me ka nui o ka seepage o 0.0001 milliliters wale nō o ka wai no kēlā me kēia kenimika kuea i kēlā me kēia makahiki—ʻoi aku ka nui ma mua o nā koi maʻamau o ka ʻoihana no ka kaohi seepage. Eia kekahi, ua hoʻokomo ʻia nā huahana me nā mea anti-aging a me nā mea hoʻohui UV-resistant, e hiki ai ke hana paʻa i nā wahi mai -70°C a 110°C. Hōʻike lākou i ke kūpaʻa ikaika i ka corrosion mai nā waikawa a me nā alkalis i hoʻopaʻa ʻia, loaʻa iā lākou ka ikaika tensile ma mua o 18 MPa, a hiki ke kū i nā ʻano geological paʻakikī a me nā kūlana aniau ʻino.
Ma ke kahua o ka ʻenekinia kaiapuni, lawelawe nā geomembranes ma ke ʻano he "pale koʻikoʻi no ka pale ʻana a me ka kaohi ʻana i ka haumia." Ua hoʻolaha pono ʻia nā geomembranes HDPE a Hongyue Environmental ma nā papahana landfill he nui—me ka Phase II o ke kikowaena mālama ʻōpala ʻo Chifeng Central Urban Area a me ka Yueyang Domestic Waste Incineration Power Generation Project. Ma o ka hoʻolālā "double-layer impermeable membrane me ka composite geomembrane", pale pono kēia mau ʻōnaehana i ka komo ʻana o ka leachate landfill, no laila e pale ana i ka haumia o ka lepo a me ka wai honua. Ma nā papahana hale hana mālama wai ʻino, hoʻohana ʻia kēia mau geomembranes i ke kūkulu ʻana i nā loko wai ʻole a me nā kīʻaha sedimentation; ua hōʻike ka nānā ʻana i mālama ʻia ma luna o kahi manawa ʻekolu makahiki i nā wahi leaka ʻole, no laila e pāʻani ana i kahi kuleana koʻikoʻi i ka hōʻoia ʻana e hoʻokō ka wai ʻino i mālama ʻia i nā kūlana hoʻokuʻu hoʻoponopono.
ʻO ka ʻenekinia mālama wai kekahi o nā hiʻohiʻona noi koʻikoʻi no nā geomembranes. Ma ka Yongtaichuan Irrigation Diversion and Storage Reservoir Project ma Jingtai County, Gansu Province, ua hoʻokani ka geomembrane HDPE textured 1.5mm-thick i hāʻawi ʻia e Hongyue Environmental Protection i kahi kuleana koʻikoʻi. Ma o kahi hoʻolālā e hoʻohana ana i ka "ʻano o ka ʻili e hoʻonui i ka friction," pale ka membrane i ka paheʻe ma nā pali waihona; i ka manawa like, ʻo kona ikaika tensile kiʻekiʻe e hiki ai iā ia ke hoʻokipa i ka hoʻonohonoho ʻana o ke kumu like ʻole, no laila e hōʻoiaʻiʻo ana i ka palekana a me ka pono o ka mālama wai o ka waihona. Eia kekahi, ua hoʻolaha pono ʻia kēia huahana ma nā papahana ʻē aʻe, me nā ʻāpana anti-seepage o ke Alanui Hikina o ka South-to-North Water Diversion Project a me nā ʻōnaehana anti-seepage subgrade no ke Alanui Kaʻaahi Kiʻekiʻe ʻo Beijing-Shanghai. I nā noi e pili ana i ka hoʻoponopono ʻana i ke kahawai muliwai a me ka hoʻoikaika ʻana i ka embankment, lawelawe ka geomembrane i kahi hana pālua - e hāʻawi ana i nā hiki anti-seepage a me ka kānana hoʻohuli - no laila e hōʻemi ana i ka ʻino o ka lepo a hoʻonui i ke kūpaʻa o ka papahana holoʻokoʻa.
Ma ke kahua o ka ʻenekinia halihali, lawelawe maikaʻi nā geomembranes ma ke ʻano he "pale pale" no nā subgrades alanui. I ka wā o ke kūkulu ʻana i nā alaloa wikiwiki a me nā alahao, hoʻohana ʻia nā geomembranes a ka Hongyue Environmental Protection ma ke ʻano he mau papa anti-seepage subgrade e pale aku i ka hau i hoʻokumu ʻia e ka piʻi ʻana o ka wai honua, a i ka manawa like e pale aku ai i ka palupalu o ka subgrade ma muli o ke komo ʻana o ka wai ua. Ma ka papahana hoʻolālā ʻāina no ke Alanui Huanglong, ua hoʻohana ʻia nā geomembranes me nā geotextiles; ʻaʻole wale kēia noi hui i hōʻoia i ke kūpaʻa o ka ʻōnaehana o ka subgrade akā ua kōkua pū i ka hoʻokahe ʻana no ka papa kanu ma luna, no laila e hoʻokō ai i nā pahuhopu pālua o ka "palekana ʻenekinia a me nā aesthetics ecological."
Ma nā ʻāpana o ka mahiʻai a me ka mahiʻai wai, ua kū mai nā geomembranes ma ke ʻano he "mea hana ikaika no ka hōʻemi ʻana i nā kumukūʻai a me ka hoʻonui ʻana i ka pono." I ke kūkulu ʻana i kahi hale hoʻoulu 10,500-sow ma Tangyin, Henan Province, ua hoʻohana ʻia ka geomembrane HDPE ʻeleʻele 0.5mm-mānoanoa o Hongyue Environmental Protection no ka uhi anti-seepage o nā digesters biogas. Me ka hoʻohana ʻana i kona hiki ke hoʻopili maikaʻi loa a me ke kūpaʻa ʻana i ka palaho, hōʻoia ka membrane i ka hōʻiliʻili pono ʻana o ka biogas me ka pale ʻana i ka leakage o nā ʻōpala holoholona a me ka haumia o ka lepo ma hope. I nā hana mahiʻai iʻa, hoʻohana ʻia nā geomembranes no ka pale ʻana i ka pali a me ka uhi ʻana i lalo o ka loko; hiki i kēia noi ke hōʻemi i ka nalowale o ka wai ma mua o 30%, kōkua i ka pale ʻana i ka laha ʻana o nā maʻi iʻa, a ma ka hopena kōkua i nā mahiʻai aquaculture i ka hoʻonui ʻana i kā lākou loaʻa kālā.
Ma waho aʻe o nā hiʻohiʻona i ʻōlelo ʻia ma luna, ua hoʻohana nui ʻia nā geomembranes a Hongyue Environmental Protection ma nā ʻano kūikawā like ʻole, me nā ʻōnaehana anti-seepage no nā loko wai o ka mine, nā uhi no nā tunnels subway, a me nā hoʻonā pale wai no nā māla ma luna o ka hale. Hāʻawi ka hui i nā lawelawe ʻokiʻoki i hana kūikawā ʻia no nā koi papahana kikoʻī a mālama i kahi hui loea ʻoihana e hāʻawi i ke alakaʻi kūkulu ma ka pūnaewele. Ma ka hāʻawi ʻana i kahi lawelawe piha, hoʻopau a hiki i ka hopena - e uhi ana i nā mea āpau mai ka "lako mea" a i ke "kākoʻo loea" - hōʻoia ʻo Hongyue Environmental Protection i ka hana anti-seepage maikaʻi loa o kēlā me kēia papahana ʻenekinia e kākoʻo nei. Ma ka hoʻohana ʻana i kā lākou kūlana mau a me nā hoʻonā kikoʻī no ke kūlana, ua hōʻea nā huahana geomembrane a Shandong Hongyue Environmental Protection ma mua o 40 mau kūlanakauhale nui a me ka waena ma Kina, me nā mea hoʻokuʻu aku e hoʻonui ana i nā wahi e like me ʻEulopa, ʻAmelika, a me Australia. I ka neʻe ʻana i mua, i ka holomua ʻana o nā papahana palekana kaiapuni a me nā ʻoihana, e hoʻomau ka Hongyue Environmental Protection i ka hoʻomaikaʻi ʻana i nā ʻenehana anti-seepage - e hoʻoikaika ana i nā "laina pale honua" no ka nui o nā papahana - no laila e hoʻomaʻamaʻa ana i ka hoʻomohala synergistic o nā ʻoihana ʻōmaʻomaʻo a me ka mālama ʻana i ke kaiapuni.
