Pepa: Ke Hoʻololi Hou ʻana i ka Benchmark no ka ʻenekinia lalo o ka honua e pale ana i ka wai me kahi "ʻano maʻalahi"
I loko o nā ʻōnaehana pale wai o nā papahana ʻōnaehana huna—e like me nā tunnels, nā subway, a me nā alaloa pono honua i hoʻohui ʻia—ʻo ke koho ʻana o nā mea e hoʻoholo pololei i ke ola palekana o kahi papahana a me nā pono kaiapuni. Ma ke ʻano he paionia hoʻolaʻa ma ke kahua o nā mea geosynthetic, ʻo Shandong Hongyue Environmental Protection Engineering Co., Ltd. (i kapa ʻia ma hope aku ʻo "Hongyue Environmental") ke puka mālie nei ma ke ʻano he "flexible" (mainstay flexible) i ka pale wai o nā wahi honua hou a me nā hale tunnel. Ma ka hoʻohana ʻana i kāna huahana koʻikoʻi—ʻo ka pepa pale wai EVA (Ethylene-Vinyl Acetate Copolymer)—ua hoʻokaʻawale ka hui iā ia iho ma o nā pono koʻikoʻi e like me ka "flexibility kūikawā, eco-friendliness, a me ka paʻa paʻa."
Ka Maʻalahi Kūikawā a me ka Hana Haʻahaʻa Haʻahaʻa: Ka Hoʻopau ʻana i ke Koʻikoʻi Kūkulu
ʻO ka mea koʻikoʻi o ka pepa pale wai EVA a Hongyue Environmental aia i kona ʻano "ʻano palupalu", e like me nā mea o ka rubber. ʻO ka hoʻokomo ʻana o nā monomers vinyl acetate i loko o kona ʻano molekala e hōʻemi nui ana i kona crystallinity, e hāʻawi ana i ka mea me kahi helu elongation kiʻekiʻe loa (≥650%). I nā noi ʻenekinia ma lalo o ka honua, hoʻopili pono ia i nā koʻikoʻi shear i hoʻokumu ʻia e ka micro-settlement o nā ʻāpana tunnel a i ʻole ke ʻano hoʻololi kumu. Ma ke ʻano he "ʻāpana hoʻonohonoho palupalu," pale ia i ka haki ʻana e hoʻopilikia pinepine i nā mea pale wai paʻa kuʻuna i ka wā e hoʻopilikia ʻia ai ke ʻano hoʻololi. Eia kekahi, ʻo kāna hana haʻahaʻa haʻahaʻa kiʻekiʻe e hōʻoiaʻiʻo ana e mālama ia i ka paʻa maikaʻi loa - me ka ʻole o ka lilo ʻana i mea palupalu a maʻalahi paha i ka haki - ʻoiai i nā wahi koʻikoʻi mai -30°C a i -35°C. ʻO kēia ka mea e kūpono loa ai no nā koi kūkulu hale ma nā wahi ʻākau anuanu a ma lalo o nā ʻano like ʻole o nā kūlana geological paʻakikī.
ʻOluʻolu i ke Kaiaola a Paʻa i nā Kemika: Mālama i ka Ecological Foundation
I kēia au o ka hoʻomohala ʻana i nā ʻōnaehana ʻōmaʻomaʻo, ua mahalo nui ʻia nā ʻano aloha kaiapuni o ka pepa pale wai EVA a Hongyue Environmental. ʻAʻohe mea ʻawahia a ʻino ʻole ka huahana ponoʻī; ʻaʻole ia e hoʻopuka i ka haumia i ka wā o ka hana ʻana a i ʻole ka hoʻohana ʻana, hana i ka ʻōpala liʻiliʻi, a kūlike piha me nā kūlana hale ʻōmaʻomaʻo. I ka manawa like, hōʻike ka mea EVA i ke kūpaʻa kemika koʻikoʻi, e pale pono ana i ka palaho mai nā waikawa, alkalis, a me nā mea kemika ʻē aʻe, me ka hōʻike pū ʻana i ke kūpaʻa maikaʻi loa i ka hydrolysis. Inā paha i hoʻohana ʻia ma nā ʻōpala kūlanakauhale e pale aku i ka haumia o ka leachate o ka lepo, a i hoʻohana ʻia paha i nā wahi palaho paʻakikī e like me nā hale hana kemika a me nā hana mining, hoʻokumu ia i kahi pale impermeable palekana a hilinaʻi hoʻi—ʻaʻohe hopena maikaʻi ʻole i nā kumu wai ma lalo o ka honua a i ʻole ke kaiapuni a puni.
Paʻa a me ke Kū'ē i ka Puncture: Ke Hōʻoiaʻiʻo nei i ka Hana o ka Papahana Wā Lōʻihi
Ma waho aʻe o kona ʻano maʻalahi, hoʻohana ʻo Hongyue Environmental i kahi kaʻina hana extrusion flat-die kiʻekiʻe i ka hana ʻana i kāna mau membrane pale wai EVA. Eia kekahi, ma muli o nā koi papahana kikoʻī, hiki ke hoʻopili ʻia nā membrane me nā geotextiles a mālama ʻia paha me kahi kaʻina hana hoʻopili one-coating, e hāʻawi ana iā lākou me ka ikaika tensile kūikawā, ke kū'ē i ka haehae, a me ke kū'ē i ka puncture. ʻAʻole wale kēia ʻano hana hui e hoʻonui i ka pono holoʻokoʻa o ka membrane akā pale maikaʻi hoʻi i ka hōʻino mechanical i ka wā o ke kūkulu ʻana a me ka hōʻino komo ʻana i hoʻokumu ʻia e nā ʻōnaehana aʻa mea kanu. Mahalo i kona kūpaʻa maikaʻi loa i ka wā a me ke kūpaʻa UV, ua haʻaheo ka mea i kahi ola lawelawe e pili ana i kekahi mau makahiki he ʻumi—inā paha i hōʻike ʻia i nā mea a i kanu ʻia paha i lalo o ka honua—no laila e hōʻemi nui ana i nā kumukūʻai mālama a me nā hoʻololi no ka papahana i ka wā e hiki mai ana.
Ka Hoʻouka Kūpono a me ka Hoʻololi Maʻalahi: Hoʻonui i ka Pono o ka Papahana
Hōʻike nā membrane pale wai EVA o Hongyue Environmental i ka hiki ke hoʻololi maikaʻi loa i ka wā o ke kau ʻana. ʻO kā lākou mau waiwai sila wela maikaʻi loa e hoʻolilo i ka wili ʻana ma kahi i mea maʻalahi loa, e hopena ana i nā humuhumu wili i paʻa loa a sila ʻia hoʻi. Eia kekahi, loaʻa ka huahana i nā ʻano mānoanoa like ʻole (e laʻa, 0.8 mm a 2.0 mm) a me nā laulā (maʻamau 3 mika a 4 mika), e ʻae ana i ka hoʻololi maʻalahi i nā hiʻohiʻona ʻenekinia like ʻole—me nā tunnels pololei, nā ʻāpana piʻo, a me nā alaloa pono haiki. Hoʻemi nui ka hoʻolālā ākea i ka helu o nā humuhumu ma kahi; i ka wā e hui pū ʻia me kahi ʻano hoʻonohonoho "zoned tensioning" i hoʻomaikaʻi ʻia e ka ʻepekema, hoʻonui nui kēia ʻano hana i ka pono o ke kūkulu ʻana a hoʻopōkole i nā manawa papahana.
Ma ka hoʻohana ʻana i kēia mau pono kūikawā, ua hoʻohana nui ʻia nā membrane pale wai EVA a Shandong Hongyue Environmental ma nā ʻāpana he nui, me nā tunnels halihali, nā papahana mālama wai a me ka kaohi kahe ʻana, nā ʻōpala hoʻoneʻe kaiapuni, a me nā ʻoihana honua ma lalo o ke kūlanakauhale. Ke kākoʻo nei i ke akeakamai o "Technological Innovation, Quality First," hāʻawi ʻo Hongyue Environmental i ka hōʻoia palekana paʻa loa a mau loa no nā laina pale huna o nā ʻoihana hou—e hāʻawi ana i nā membrane pale wai EVA hana kiʻekiʻe i hana ʻia e "kūʻē i ka deformation" a "kū i ka corrosion."
