Ngā Painga o ngā Geomembranes

I te mea kei te piki haere tonu ngā whakaritenga kounga mō te whakahaere i te turuturu i roto i te tiaki wai, te tiaki taiao, me ngā kaupapa hangarau ā-tāone, kua noho ngā geomembranes mahi-teitei hei rauemi matua e kore e taea te wareware i roto i te hanganga hangarau hou. Hei umanga tohu e tipu haere ana i roto i te rāngai geosynthetics o Haina, ko Shandong Hongyue Environmental Engineering Co., Ltd.—mā roto i tana whakapau kaha ki te R&D me te whakahaere kounga pakari—e whakaputa ana i tētahi raupapa hua geomembrane (tae atu ki te HDPE) e whakamanamana ana i ngā painga matua e ono: te whakahaere i te turuturu pai, te ātete ki te waikura tino pai, te roa o te wā, te pai o te hanga, te hoahoa taiao, me te whai hua o te utu. He whānuitia te whakamahinga o ēnei hua i roto i ngā mara pēnei i te hanganga whenua ururua, te aukati i te turuturu tiaki wai, te ahuwhenua ika, me te hangarau ā-tāone. Kua angitu a Hongyue ki te tiaki i ngā kaupapa matua maha—tae atu ki te Awa o Hutuo, te Pūnaha Wai Mowhiti o te Tāone o Baoding, me te Whenua ururua o Jinan—nā reira i whakatū ai i tētahi paearu hou mō te kounga i roto i te umanga.
I. Te Mana Whakamutunga Tino Pai: Kāore he maturuturunga kotahi e mawhiti
Ka hangaia ngā geomembranes taiao o Hongyue mā te whakamahi i te kapia wahine kounga teitei o te Polyethylene Matotoru Teitei (HDPE) me te tukanga whakaputa-tahi paparanga-toru matatau. Ko te tauwehenga uruhanga o ngā hua he iti iho i te 1×10⁻¹⁷ cm/s—he nui ake i te paerewa ā-motu (GB/T 17643-2011)—nā reira ka tutuki he pānga whakahaere-mimi e tata ana ki te "kore turuturu." Ahakoa e mahi ana ki te wai para whenua, ki te wai para, ki ngā wai noa rānei, ka ārai pai ngā geomembranes i te urunga mai, ka whakakore i ngā tūponotanga turuturu i te pūtake me te hanga i tētahi "ārai wai" kore e taea te uru mō te kaupapa hangarau.
II. Ātete Tino Pai ki te Waikura: Kore e mataku ki te Waikura
He tino pakari ngā matū o ngā hua, ā, ka taea te tu atu i te pānga roa ki ngā momo waikura—tae atu ki ngā waikawa kaha, ngā turanga kaha, ngā tote, me ngā hinu—i roto i te awhe pH mai i te 2 ki te 13. Ahakoa i roto i ngā taiao tino waikura—pērā i ngā whenua ururua, ngā puna waipara matū, me ngā puna keri para—ka mau tonu te hanganga me te mahi pumau o ngā geomembranes; kāore e pirau, e pakarukaru, e rahua rānei, ā, mā reira ka whakarite kia roa te haumaru o ngā kaupapa hangarau i raro i ngā āhuatanga mahi uaua.
III. Te Pakari i te Pāmahana Whānui: Te Ora Ratonga Roa
Mā te whakauru i ngā tāpiri motuhake—pērā i te pango waro kounga teitei, ngā ārai mate, me ngā ārai UV—he ātete tino pai ki te huarere me ngā āheinga ārai-pakeke o ngā hua. He whānui te awhe pāmahana e whakamahia ana mai i te -70°C ki te 110°C, e āhei ai te tu atu i ngā āhuatanga taiao kino pērā i te makariri rawa, te wera nui, te pānga UV nui, me te ua nui. Ahakoa kei waho, kei raro rānei i te whenua, ka roa te ora o te rauemi mō te 30 ki te 50 tau—he nui ake i ngā rauemi ārai-mimi tuku iho—ā, ka whakaitihia ngā utu tiaki mō te wā roa mō ngā kaupapa hangarau.
IV. He pai mō te taiao, he haumaru, ā, kāore he paitini
Kāore he tāpiringa paitini, he konganuku taumaha rānei i roto i te hua; kua whiwhi tiwhikete hei "Rauemi Hanga Kakariki me te Hoa-Taiao" ā, e tutuki katoa ana i ngā paerewa haumaru taiao ā-motu. He haumaru mō te whakapā tika ki te wai inu me ngā taiao ahuwhenua ika, kāore he paitini, kāore he kakara, ā, kāore hoki e poke. Ehara i te mea ka ārai pai i te horapa o ngā poke - mā reira ka tiakina te oneone me ngā pūnaha wai whenua - engari ka taea hoki te hangarua i te rauemi tonu, ka tino tutuki ai he taurite pai me te whai hua i waenga i te hanganga hangarau me te tiaki taiao.
"Ka tīmata te kounga hangarau i ngā rauemi e whakamahia ana. Kei te mau tonu tā mātou whakapau kaha ki te whakatairanga i ngā whakapainga hua mā te auahatanga hangarau, me te whakarato i ngā otinga tino pono mō te ārai i te wai e whakamahia ana ki ō mātou kiritaki," te kī a tētahi māngai mō te Tiaki Taiao o Shandong Hongyue. "Ka mau tonu te wairua o te mahi toi a te kamupene, me te whakamahi i ā mātou hua o te ao me ngā ratonga whānui hei āwhina i te whakapakari i ngā turanga ārai i te wai o ngā kaupapa puta noa i te motu, kia whai wāhi nui ai ki te tiaki taiao me te whakawhanaketanga hanganga."
