E mōhiotia whānuitia ana te kounga ongā ngongo tapawhā me ngā ngongo tapawhā kua whakakanapahiaā, ka pā tika te tikanga tāutanga ki te pumau o ngā hanganga maitai.
I tēnei wā, ko ngā rauemi tautoko kei te mākete ko te nuinga o te maitai waro. Ko ngā rauemi mata o te maitai waro ko te Q235 me te Q345, ā, ka tukatukahia mā te whakawera wera. Ko te tautoko he mea hanga ki te koiri maitai rīpene mā te piko makariri, te whakarewa, te whakawera wera me ētahi atu tukanga. Ko te tikanga, me nui ake te matotoru i te 2mm, ā, mō ētahi wāhi takutai moana, whare teitei me ētahi atu wāhi hau nui, e taunakihia ana kia kaua e iti iho i te 2.5mm te matotoru, ki te kore ka pakaru te pūwāhi hononga maitai.
I roto i ngā hanganga whare nui, mōpaipa tapawhā me te tapawhā whakapūmau maitai waro, kia pēhea te matotoru o te paninga konutea me tutuki kia tutuki ai ngā whakaritenga o te roanga mahi waikura taiao?
E mōhio ana tātou katoa, ko te matotoru o te whakarewa wera he tohu kounga me te hangarau nui opaipa tapawhā piauau, e pā ana ki te haumaru me te pakari o te hanganga. Ahakoa he paerewa ā-motu me ngā paerewa ngaio, ko te matotoru o te paninga konutea o te tautoko he raruraru hangarau whānui tonu o te tautoko.
Ko te tukanga whakapūmau wera he mahere maimoatanga mata maitai pumau, pono hoki hei ārai i te waikura taiao. He maha ngā āhuatanga e pā ana ki te whakapūmau wera, pērā i te hanganga o te papa maitai, te āhua o waho (pērā i te taratara), te ahotea o roto o te papa, me ētahi rahi. I roto i tēnei tukanga, he nui ake te pānga o te matotoru o te papa ki te matotoru o te whakapūmau wera. I te nuinga o te wā, ko te matotoru o te pereti, ko te nui ake o te matotoru o te whakapūmau wera. Ko te tautoko me te matotoru o te 2.0mm ka tangohia hei tauira hei whakaatu i te matotoru o te paninga konutea e hiahiatia ana hei whakatutuki i ngā whakaritenga roa o te waikura taiao.
Me kī ko te matotoru o te rauemi turanga tautoko he 2mm, e ai ki te paerewa whakawai wera GBT13192-2002.
He aha te matotoru o te paparanga piauau o te paipa tapawhā piauau e hiahiatia ana hei whakatutuki i ngā whakaritenga roa o te ora?
Paipa tapawhā piauau
E ai ki ngā whakaritenga o te paerewa ā-motu, kaua te matotoru o te rauemi turanga 2mm e iti iho i te 45 μm. Kaua hoki te matotoru ōrite e iti iho i te 55 μm. E ai ki ngā hua o te whakamātautau pānga hau i whakahaerehia e te Japanese Hot Dip Galvanizing Association mai i te tau 1964 ki te 1974. He aha te matotoru o te paparanga piauau o te paipa tapawhā piauau e hiahiatia ana hei whakatutuki i ngā whakaritenga roa o te mahi?
Ki te tatauhia kia rite ki te paerewa ā-motu, ko te nui o te konutea he 55x7.2=396g/m2,
Ko te roa o te ora e wātea ana i roto i ngā taiao rerekē e whā e pā ana ki:
Rohe ahumahi taumaha: 8.91 tau, me te nekehanga waikura ā-tau o te 40.1;
Rohe takutai: 32.67 tau, me te nekehanga waikura ā-tau o te 10.8;
Ngā taha o waho: 66.33 tau, me te nekehanga waikura ā-tau o te 5.4;
Rohe tāone: 20.79 tau, me te nekehanga waikura ā-tau o te 17.5
Ki te tatauhia i runga i te roanga o te ratonga photovoltaic o te 25 tau
Kātahi ka pēnei te raupapa o ngā rohe e whā:
1002.5270135437.5, arā 139 μm, 37.5 μm, 18.75 μm, 60.76 μm.
Nō reira, mō te tohatoha o ngā tāone nui, me 65 μM te matotoru o te paninga konutea, he mea tika, he mea tika hoki, engari mō ngā wāhi ahumahi taumaha, inā koa ko ērā he waikura waikawa me te kawakore, e taunakihia ana kia tāpirihia te matotoru o te paipa tapawhā piauau me te paninga konutea.
