Ka hoʻomaopopo ʻana i nā ʻano a me nā mea waiwai

ʻOkoʻa nā ʻano alapiʻi kelepona maʻamau e pili ana i nā mea a me nā ʻano, e mālama ana kēlā me kēia i nā kūlana hana. ʻO ka mea maʻamau i hoʻohana ʻia ʻo ia ka carbon structural steel Q235B, i ʻike ʻia no kona hiki ke loaʻa, affordability, stable mechanical properties, a me ka mālama ʻana i ka ʻili. Eia naʻe, hiki i nā kūlana hana kūikawā ke koi i nā mea ʻē aʻe.

ʻO ka palena o ka mea Q235B he 235MPA, i hōʻike ʻia e ka haʻahaʻa carbon content a me ka paʻakikī maikaʻi loa, e kūpono ana ia no ka hoʻomaʻamaʻa anu, kulou, a me ka wili. No nā alapiʻi uwea, hoʻopiʻi pinepine ʻia nā alahao ʻaoʻao a me nā crossbars e hoʻomaikaʻi i ka paʻakikī, me ka nui o nā pilina e welded ʻia, e hōʻoia ana i ke kūpono no nā kūlana hana like ʻole.

I ka wā e pili ana i ka pale ʻana i ka corrosion, ʻo ka hapa nui o nā alapiʻi uwea waho i hana ʻia me ke kila māmā a hoʻomaʻamaʻa ʻia i ka wela wela. ʻO kēia kaʻina hana i ka mānoanoa o ka zinc layer o 50 a i 80 μm, e hāʻawi ana i ka pale ʻana i ka ʻōpala no nā makahiki he 10 ma nā wahi maʻamau o waho. No nā noi i loko, ʻoi aku ka maikaʻi o nā alapiʻi kaula alumini ma muli o ko lākou pale ʻana i ka corrosion. Hoʻopili pinepine ʻia nā huahana alumini i ka mālama ʻana i ka oxidation o ka ʻili no ka hoʻonui ʻana i ka lōʻihi.

ʻO nā alapiʻi kaula kila kila, e like me SS304 a i ʻole SS316, ʻoi aku ke kumu kūʻai akā pono no nā kaiapuni kūikawā e like me nā moku, nā halemai, nā mokulele, a me nā mea kanu kemika. ʻO SS316, nickel-plated ma hope o ka hana ʻana, hāʻawi i ke kūpaʻa ʻoi aku ka maikaʻi no nā kūlana koʻikoʻi e like me ka ʻike ʻana i ke kai. Hoʻohui ʻia, hoʻohana ʻia nā mea ʻē aʻe e like me ke aniani fiber reinforced plastic no nā papahana kikoʻī e like me nā ʻōnaehana pale ahi huna, kēlā me kēia koho waiwai e pili ana i nā koi o ka papahana.

ka hoomaopopo ananūhou pāʻoihanaʻO ka ʻike ʻana i ka hopena o nā koho waiwai i ka hana ʻana a me ke koʻikoʻi o ka mālama ʻana i ka ʻili i ka hōʻoia ʻana i ka lōʻihi o ka huahana a me ka hana. Ke ulu nei nā ʻoihana, ʻo ka noi no nā alapiʻi kelepona i hoʻolālā ʻia no nā kūlana like ʻole e hoʻomau i ka neʻe ʻana i ka hana hou a me ka holomua ʻenehana i ka mākeke. ʻO ka nānā ʻana i nā koi kūikawā o nā kaiapuni like ʻole hiki ke alakaʻi i nā ʻoihana i ke koho ʻana i nā mea kūpono loa no kā lākou mau papahana alapiʻi kaula, e hoʻonui ai i ka pono o ka hana a me ka lōʻihi.
