ʻO nā pā ʻauamo hao hao he mea koʻikoʻi loa ia-e lawe ana i nā mea pili i nā laina hoʻouna ma luna o ke poʻo a me nā hale waihona. Lawe lākou i nā hana koʻikoʻi e like me ka hoʻoili ukana, ka hoʻokuʻu ʻana i ke kaula insulator, a me ka hoʻoponopono conductor. ʻO kā lākou mau waiwai mechanical, ka pololei o ka dimensional, ka pale ʻana i ka corrosion, a me ka paʻa o ka hoʻolālā e hoʻoholo pololei i ka palekana o ka hana laina. ʻAʻole hāʻawi wale ʻo Hot- galvanizing i ka mea hana me ka pale corrosion ʻelua -pale kino a me ka pale cathodic-akā, he hopena nui nō hoʻi i ka pā kila, ka pololei o ke ana, ke ʻano o ka ʻili, a me nā waiwai mechanical i ka wā -kiʻekiʻe ka hoʻoinu ʻana i ka wela, ka hopena kemika, a me nā kaʻina hoʻolili wikiwiki. Hoʻonui nui kēia mau hopena i nā hana maikaʻi o ka pā ʻauamo kila galvanized.
Ma ke ʻano he haʻawe-pono, ʻo nā ʻano mekini nui o nā pā ʻauamo hao hao, ʻo ia ka ikaika tensile, ka ikaika hāʻawi, ka elongation, ka paʻakikī o ka hopena, a me ka paʻakikī. Loaʻa nā mea maʻamau i ka Q235B, Q355B, ASTM A36, a me A572 Gr50, ʻo ia mau mea a pau he mau hao hao haʻahaʻa. He 440–460 degere ka wela -wea wela, ma lalo o ka mahana hana hoʻoponopono hou o ke kila, no laila ʻaʻole i emi nui ka ikaika o ke kumu. ʻO ka maʻamau ka hoʻololi ʻana o ka ikaika tensile<5%, generally maintaining factory-set levels. Yield strength fluctuates slightly but remains generally stable. Due to the high-temperature tempering effect, internal stress is slightly released, and plasticity is slightly improved. Short-term high-temperature holding causes a slight decrease in surface hardness, which does not affect the overall load-bearing capacity.
He kiʻekiʻe loa nā koi no ka anawaena puka, ka ʻokoʻa o ka lua, ka pālahalaha, ka perpendicularity, a me nā ana holoʻokoʻa. ʻO - galvanizing wela ke kaʻina hana nui e hoʻokaʻawale ai i ka nui, me nā mea e like me ka mānoanoa o ka papa zinc, ka hoʻololi ʻana i ke koʻikoʻi wela, a me ka emi ʻana o ka hoʻoilo. I ka wā o ka hana ʻana, ʻo kā mākou koi maʻamau no ka mānoanoa pā he awelika ka mānoanoa papa zinc o ʻoi aʻe a like paha me 86μm no nā papa ʻoi aku ka nui a i ʻole like me 6mm, me ka mānoanoa kūloko a hiki i 100–120μm. Ma kahi o 0.08–0.12mm ka nui o ka nui ma kēlā me kēia ʻaoʻao, me ka piʻi ʻana o ka nui ma lalo o 0.24mm a i ʻole like. I loko o nā ʻae ʻae ʻia, e emi ana ke anawaena puka ma ka 0.16–0.24mm, me ka liʻiliʻi o ka hopena i ka hui bolt maʻamau. Ma muli o ka hoʻopili ʻana o ka papa zinc like ʻole, ʻaʻole i hoʻololi maoli ʻia ke kūlana waena waena, me ka ʻokoʻa ʻaʻole i like a i ʻole 0.1mm.
Hoʻoholo pololei ʻo - galvanizing wela i ke kūlana ili o nā pā ʻauamo hao hao, e pili ana i ka helehelena, ka maʻalahi, nā nodule zinc, a me nā burr. Hoʻokumu ia i kahi ʻāpana zinc hinahinahina -hina, e hōʻemi ana i ka maikaʻi o ka nānā ʻana, e uhi ana i nā māka mīkini, nā ʻōpala liʻiliʻi, a me ka oxidation, e hoʻokō i nā kūlana hiʻohiʻona o nā huahana i waho, e hōʻemi ana i ka ʻōpala keʻokeʻo, a me ka hana ʻana i kahi ʻili maʻemaʻe.
Hoʻolālā maʻamau nā papa ʻauamo kila galvanized no ke ola o 20-30 mau makahiki. He hōʻailona kumu ke kūpale ʻino, a ʻo ka -dip galvanizing wela ke kaʻina hoʻoholo no ka hoʻomaikaʻi ʻana i ke kūpaʻa ʻino; ʻaʻohe mea ʻē aʻe. Hoʻokaʻawale ka mīkini pale corrosion ʻelua, me kahi papa zinc paʻa, hoʻokaʻawale i nā media corrosive e like me H₂O, O₂, Cl⁻, a me SO₂, me ka zinc makemake i ka corroding, e pale ana i ka substrate kila mai ka ʻōpala. Ma hope o ka -luu wela, hiki i ka pā ʻauamo ke kū i nā kaiapuni o ka lewa maʻamau, nā kaiapuni paʻakai kahakai, nā kaiaua wai ʻakika ʻoihana, a me ka haʻahaʻa kiʻekiʻe a me nā kaiapuni waho UV kiʻekiʻe.
Hoʻopili ʻia nā laina hoʻouna i ka haʻalulu makani, nā haʻalulu hau, ke koʻikoʻi o ka mahana, a me ka haʻalulu conductor i nā manawa lōʻihi. Pono ka pale ʻana i ka luhi maikaʻi loa i nā papa hoʻohui, a he hopena koʻikoʻi ka hoʻoheheʻe ʻana i ka wela -dip galvanizing i kēia. Wehe -wela weuweu e hoʻopau i ke koʻikoʻi o loko mai ka hana ʻana, hoʻemi i ka hiki ke hoʻomaka ʻia ka māwae luhi, keʻakeʻa i ka ʻino ʻana o ka lua o ka ʻili, pale i ka ʻūhā -ka māwae luhi, hoʻopaʻa i ka microstructure, a ʻaʻole hoʻololi i ka nui i ka wā lawelawe lōʻihi.
ʻAʻole hiki ke hoʻopilikia i ka haʻawe hana -hana o nā papa ʻauamo hao hao; ma ka mea ʻē aʻe, hoʻomaikaʻi nui ia i ka pale ʻana i ka corrosion a me ka hilinaʻi o ka hana, hana ia i mea koʻikoʻi no ka hōʻoia ʻana i ka waiwai o ka huahana.
