I roto i ngā kaupapa hangarau huna—pērā i ngā kauhanga, ngā ara raro whenua, me ngā ara ratonga o raro whenua—ehara i te mea he arai noa iho ngā kiriuhi ārai wai hei wehe i te wai, engari he "wāhanga ngāwari" hoki e whai wāhi kaha ana ki te whakahaere i te ahotea hanganga. Hei kaihanga motuhake i roto i te mara o te geosynthetics, kua whakamahia e Shandong Hongyue Environmental Engineering Co., Ltd. (e kiia nei i muri nei ko "Hongyue Environmental") tōna tohungatanga hangarau hohonu ki ngā kiriuhi ārai wai EVA (Ethylene-Vinyl Acetate Copolymer) hei hanga i tētahi pūnaha hanga pūtaiao, pakari, me te paerewa. Mā roto i ngā tikanga matua e toru—"te kōwhiringa rauemi tika, te whakarewatanga tino tika, me te whakapūmau paerewa"—ka whakamahia katoatia e te kamupene ngā āhuatanga tino pai o ngā kiriuhi EVA, tae atu ki te roa teitei, te ātete pāmahana iti, me te kaha haehae, ā, nā reira ka whakatūria he parenga ārai wai e kore e taea te wawahi mō te whānuitanga o ngā kaupapa hangarau.
Hipanga Tuatahi: Te Kōwhiringa Rauemi Tika me te Whakarite Papatūāpapa—Te Whakatakoto i tētahi Tūāpapa Tino Pai
Ka tīmata te kaupapa ārai wai kounga teitei me te whakahaere tika i ngā rauemi. Ka whakamahia e ngā kiriuhi ārai wai EVA a Hongyue Environmental te Ethylene-Vinyl Acetate Copolymer kounga teitei hei rauemi mata matua; he rite ki te rapa te ngāwari, he tino ngāwari ki te pāmahana iti (ka mau tonu te ngāwari ahakoa i roto i ngā āhuatanga makariri mai i te -30°C ki te -35°C), ā, he kaha te haehae. I mua i te hanganga, me tino whakarite te papa: me papatahi te mata o te turanga, me totoka, me te kore he hapa, he mea koi rānei, me te whakarite kia kore he wai e tū ana, he paru hinu, he puehu rānei. I runga i te rahi o te kaupapa me tōna taiao mahi motuhake, ka tukuna e Hongyue Environmental ngā kiriuhi ārai wai EVA kua whakaritea i roto i ngā matotoru rerekē—mai i te 0.5 mm ki te 2.5 mm—kia pai ai te taurite i waenga i te mahi rauemi me ngā whakaritenga hangarau.
Hipanga Tuarua: Ngā Tukanga Whakarewa Pūmau—Te Whakatau i te Roa o te Ora o te Pūnaha Ārai Wai
I te wā e hangaia ana i te papaanga, ko te pono o te kiriuhi ārai wai e whakawhirinaki ana ki te 90% o te kounga o te whakarewa hau wera. E whakanui ana te tīma hangarau o Hongyue Environmental me whakarērea te whakaaro hē o te whakamahi i te whakarewa hei "mahi hipoki" anake; engari, me matua whakarite hei tukanga matua, tino nui. Me whakahaere te hanganga ma te whakamahi i ngā mīhini whakarewa motuhake, i ngā pū whakarewa hau wera rānei, me te whakahaere tika i te pāmahana putanga hau i roto i te awhe o te 320°C ki te 380°C. I mua i te whakarewa, me whakahaere tika te whānui taupatupatu i waenga i ngā pepa kiriuhi tata i waenga i te 70 mm me te 100 mm, ā, me whakamahi he paraihe waea maitai hei tango pai i te puehu mata, i ngā paparanga waikura rānei mai i ngā wāhi taupatupatu. I te wā e hangaia ana te whakarewa, ka whakamahia he pāmahana teitei hei whakarewa i te mata o te rauemi EVA, ā, muri iho ka whakamahia he pēhanga hei whakakotahi i ngā paparanga ki roto i te wae kotahi, piri. Ko te manatoko i muri i te whakarewa he tukanga tirotiro tino pakari e toru nga taahiraa: Tuatahi, ka whakahaerehia he tirotiro tirohanga hei whakarite kia puta te hononga whakarewa hei whakaotinga ōrite, mārama, rite ki te karāhe, karekau he mirumiru, he kita rānei. Tuarua, ka whakahaerehia he whakamātautau kiri ā-mīhini; ina whakamahia te kaha kume poutū ki te hononga whakarewa, me noho tonu kia kore e pakaru. Tuatoru, ki te tika, ka whakahaerehia he whakamātautau pupuhi hei manatoko kei roto tonu te pirau pēhanga i ngā rohe paerewa kua whakaritea.
Hipanga 3: Te Whakapūmau me te Whakatakoto Pūtaiao—Te Whakakore i te Mōrearea o ngā "Whakapiri Hē"
I te wā e hangaia ana i ngā wāhi uaua—pērā i ngā karauna kauhanga—ka taea e te taumaha o te rauemi te whakaheke ngāwari, ka arahi ki ngā "whakapiri rūpahu" (ngā hononga kore oti, ngoikore rānei). E whakanui ana a Hongyue Environmental Protection i te hiranga o te whakamahi i tētahi tikanga "whakapiri rohe me te whakapiri wāhanga". Ko te tikanga tuatahi ko te whakau i te kiriuhi ārai wai ki te papa ma te whakamahi i ngā whitiki motuhake e wehea ana i te 300mm te tawhiti; kātahi ka tukuna te whakaheke wāhanga i ia wāhanga, me te whakapiri i te wā kotahi. Ka ārai pai tēnei tikanga i te putanga mai o ngā whakapiri rūpahu i puta mai i te whakahekenga o te rauemi i raro i tōna ake taumaha, kia mau ai he hononga piri, piripono i waenga i te kiriuhi ārai wai me te hanganga tautoko tuatahi. Hei tāpiri, he whānui te hototahitanga o ngā kiriuhi ārai wai EVA ki ngā momo piripiri; i te wā e rongoatia ana ngā kokonga, ngā urunga paipa, me ētahi atu wāhi uaua, ka taea te whakamahi i ngā piripiri motuhake hei whakatutuki i te hiri tere me te whai hua, kia pai ake ai te ātete whānui o te pūnaha ārai wai.
Mā te whakamahi i tēnei huinga tikanga hanga paerewa, ka taea e ngā kiriuhi ārai wai EVA a Shandong Hongyue Environmental Protection te whakaatu katoa i ō rātou painga matua—tae atu ki te ātete tino pai ki te waikura, te ātete ki te urunga o te pakiaka, me te roa o te ora mahi.
