Nā Pōmaikaʻi o Geomembranes

I ka piʻi ʻana o nā koi maikaʻi no ka kaohi ʻana i ke kahe ʻana o ka wai i ka mālama ʻana i ka wai, ka palekana o ke kaiapuni, a me nā papahana ʻenekinia kūlanakauhale, ua lilo nā geomembranes hana kiʻekiʻe i mea koʻikoʻi i ke kūkulu ʻana i nā ʻenekinia hou. Ma ke ʻano he ʻoihana hoʻohālikelike e piʻi nei ma ka ʻāpana geosynthetics o Kina, ʻo Shandong Hongyue Environmental Engineering Co., Ltd.—ma o kona kūpaʻa hohonu i ka R&D a me ka kaohi maikaʻi koʻikoʻi—e hana i kahi moʻo o nā huahana geomembrane (me HDPE) e haʻaheo ana i ʻeono mau pono koʻikoʻi: kaohi ʻana i ke kahe ʻana o ka wai, ke kūpaʻa ʻana i ka palaho, ka lōʻihi o ka lōʻihi, ka pono kūkulu kiʻekiʻe, ka launa ʻana i ke kaiapuni, a me ka pono o ke kumukūʻai. Hoʻohana nui ʻia kēia mau huahana ma nā kahua e like me ke kūkulu ʻana i nā ʻōpala, ka pale ʻana i ke kahe ʻana o ka wai, ka mahiʻai wai, a me ka ʻenekinia kūlanakauhale. Ua palekana pono ʻo Hongyue i nā papahana koʻikoʻi he nui—me ka muliwai ʻo Hutuo, ka ʻōnaehana wai ʻo Baoding City Ring, a me ka Jinan Landfill—no laila e hoʻokumu ana i kahi hoʻohālikelike hou no ka maikaʻi i loko o ka ʻoihana.
I. Ka Mana Hoʻokahe Loa: ʻAʻohe Holo Hoʻokahi o ka Holo ʻana
Hana ʻia nā geomembranes kaiapuni ʻo Hongyue me ka hoʻohana ʻana i ka resin puʻupaʻa High-Density Polyethylene (HDPE) kiʻekiʻe a me kahi kaʻina hana co-extrusion ʻekolu papa holomua. Loaʻa i nā huahana kahi coefficient permeability haʻahaʻa e like me 1 × 10⁻¹⁷ cm/s—ʻoi aku ka maikaʻi ma mua o ke kūlana aupuni (GB/T 17643-2011)—no laila e hoʻokō ai i kahi hopena kaohi seepage e hoʻokokoke aku ana i ka "zero leakage." Inā paha e hana ana me ka leachate landfill, ka wai hoʻoneoneo, a i ʻole nā ​​​​kino wai maʻamau, pale pono nā geomembranes i ka infiltration, e hoʻopau ana i nā pilikia leakage ma ke kumu a kūkulu i kahi "pale pale wai" hiki ʻole ke komo no ka papahana ʻenekinia.
II. Ke Kū'ē Kūikawā i ka ʻAi ʻAna: wiwo ʻole i ka ʻAi ʻAna
Hōʻike nā huahana i ke kūpaʻa kemika koʻikoʻi, hiki ke kū i ka hoʻopili lōʻihi ʻana i nā ʻano mea ʻino like ʻole—me nā waikawa ikaika, nā kumu ikaika, nā paʻakai, a me nā aila—i loko o ka pae pH o 2 a 13. ʻOiai ma nā wahi ʻino loa—e like me nā ʻōpala lepo, nā loko wai hoʻoheheʻe kemika, a me nā loko wai hoʻoheheʻe ʻeli—mālama nā geomembranes i ko lākou kūpaʻa kūkulu a me ka hana paʻa; ʻaʻole lākou e pala, lilo i mea palupalu, a hāʻule paha, no laila e hōʻoiaʻiʻo ana i ka hana palekana lōʻihi o nā papahana ʻenekinia ma lalo o nā kūlana hana paʻakikī.
III. Ka Paʻa o ka Mahana Laulā: Ola Hana Lōʻihi
Ma ka hoʻohui ʻana i nā mea hoʻohui kūikawā—e like me ke kalapona ʻeleʻele kiʻekiʻe, nā antioxidants, a me nā mea hoʻomoʻa UV—ua hāʻawi ʻia nā huahana i ke kūpaʻa ʻana i ka wā a me nā hiki ke kūʻē i ka ʻelemakule. He ākea ka laulā o ka mahana e pili ana mai -70°C a i 110°C, e hiki ai iā ia ke kū i nā kūlana kūlohelohe ʻino e like me ke anu nui, ka wela wela, ka ʻike UV nui, a me ka ua nui. Inā paha i hōʻike ʻia i nā mea ma waho a i kanu ʻia paha i lalo o ka honua, hāʻawi ka mea i kahi ola lawelawe o 30 a 50 mau makahiki—ʻoi aku ka maikaʻi ma mua o nā mea anti-seepage kuʻuna—no laila e hōʻemi nui ana i nā kumukūʻai mālama lōʻihi no nā papahana ʻenekinia.
IV. Aloha i ke kaiapuni, palekana, a ʻaʻohe mea ʻawahia
ʻAʻohe mea hoʻohui ʻawahia a me nā metala kaumaha i loko o ka huahana; ua loaʻa iā ia ka palapala hōʻoia ma ke ʻano he "Mea Hana Hale ʻŌmaʻomaʻo a me ke Aloha ʻĀina" a ua kūlike piha me nā kūlana palekana kaiapuni aupuni. He palekana ia no ka hoʻopili pololei ʻana me ka wai inu a me nā wahi mahiʻai wai, ʻaʻohe ʻawahia, ʻaʻohe ʻala, a ʻaʻohe haumia. ʻAʻole wale ia e pale pono i ka laha ʻana o nā mea haumia—a pēlā e pale ai i nā ʻōnaehana lepo a me ka wai honua—akā hiki ke hana hou ʻia ka mea ponoʻī, e hoʻokō maoli ana i kahi kaulike kūlike a pōmaikaʻi hoʻi ma waena o ke kūkulu ʻenekinia a me ka mālama ʻana i ke kaiapuni.
"Hoʻomaka ka maikaʻi o ka ʻenekinia me nā mea i hoʻohana ʻia. Ke kūpaʻa nei mākou i kā mākou kūpaʻa e hoʻokele i nā hoʻonui huahana ma o ka hana hou ʻenehana, e hāʻawi ana i kā mākou mea kūʻai aku me nā hopena anti-seepage hilinaʻi loa," wahi a kekahi ʻelele mai Shandong Hongyue Environmental Protection. "E hoʻomau ka hui i ka mālama ʻana i ka ʻuhane o ka hana lima, e hoʻohana ana i kā mākou huahana papa honua a me nā lawelawe piha e kōkua i ka hoʻoikaika ʻana i nā kumu anti-seepage o nā papahana ma ka ʻāina holoʻokoʻa, no laila e hāʻawi nui ana i ka mālama ʻana i ke kaiapuni a me ka hoʻomohala ʻana i nā ʻoihana."
