Hoʻolauna Huahana
ʻO ka PC-strand, galvanized-greased-PE-coated (i kapa ʻia ʻo Hot-dip galvanized unbonded steel strand) he mea hana koʻikoʻi a me ka ʻenekinia e hāʻawi ana i ka hana ikaika a paʻa no nā ʻano noi. ʻO ke kaʻina hana galvanizing wela e hoʻokomo i nā kaula kila i loko o ka zinc i hoʻoheheʻe ʻia e hāʻawi i kahi uhi pale, e hana ana i kahi uhi paʻa a me ka corrosion i loko a me ka ʻili o ke kaula pc.
ʻO kēia mau kaula he "hoʻopaʻa ʻole," ʻo ia hoʻi ʻaʻole lākou e hoʻopaʻa i ke kaʻa a puni, e ʻae ai i ka maʻalahi a me ka neʻe. Ma muli o kona ikaika tensile kiʻekiʻe a me ka pale ʻana i ka corrosion, hoʻohana mau ʻia kēia ʻano strand i nā hana kūkulu e like me ka post-tensioning a me ka prestressed concrete structures.
Nā hiʻohiʻona huahana
1) Ka hana a me nā noi ʻana i ka Corrosion Resistant:
Hāʻawi ka uhi galvanized hot-dip i ka pale maikaʻi loa i ka ʻino, e hana ana i nā kaula kila i kūpono no nā noi ma nā wahi paʻakikī e like me ke kūkulu ʻana i ke kai, nā alahaka a me nā hale kahakai.
2) Kiʻekiʻe tensile ikaika:
Loaʻa i kēia mau kaula kila ka ikaika tensile kiʻekiʻe, e hoʻolilo iā lākou i mea kūpono no nā hale paʻa paʻa mua a post-tensioned. Hāʻawi lākou i ke kūpaʻa a me ke kākoʻo no nā ʻano hana kūkulu.
3) Hiki ke maʻalahi:
ʻO nā kaula i hoʻopaʻa ʻole ʻia e hāʻawi i ka ʻoi aku ka maʻalahi a me ka neʻe ʻana i loko o nā hale paʻa, e kūpono ana ia no nā kaiapuni hoʻouka ikaika, nā wahi seismic a me nā noi kahi e pono ai ka neʻe a me ke kaumaha.
4) Loihi:
Hoʻonui ka galvanized coating i ke ola lawelawe o nā kaula kila, e kōkua ana i ka hoʻonui ʻana i ka paʻa a me ke kūpaʻa o nā hale me ka hoʻohana ʻana i nā kaula kila.
Nā noi huahana
Hoʻohana nui ʻia nā huahana hopena i ke kūkulu ʻana, ka ʻenekinia kīwila a me nā papahana ʻoihana ma muli o ko lākou pale ʻana i ka corrosion, ka ikaika tensile kiʻekiʻe a me ka maʻalahi.
Hoʻohana: Hoʻohana mau ʻia nā kaula hao wela wela i nā ʻano hana like ʻole e like me ke kūkulu ʻana i ke alahaka, nā hale kiʻekiʻe, nā pili kaʻaahi, nā mea kanu nuklea, a me nā hana ʻenekinia a me nā ʻoihana ʻē aʻe.
Nā Pono Huahana
1) Ka lōʻihi:
ʻO kahi pale galvanized coating e hoʻonui nui i ke ola o ke kaula, e hōʻemi ana i nā kumukūʻai mālama a hoʻomaikaʻi i ka hana lōʻihi.
2) Pale ʻino:
ʻO nā pale galvanized ka mea e pale ai, e pale ana i ke kila mai ka makū, nā kemika, a me nā mea kūlohelohe e hiki ai ke hōʻeha a me ka hōʻino.
3) Hoʻemi ʻia ka pilikia o ka haki ʻana:
ʻO ka ikaika tensile kiʻekiʻe o nā kaula kila, i hui pū ʻia me ka maʻalahi i hāʻawi ʻia e kahi hoʻolālā hoʻopaʻa ʻole, e hōʻemi i ka pilikia o ka haki ʻana a me ka hōʻoia ʻana i ka pono o ke kūkulu ʻana.
4) Hiki
ʻO ke kaula kila non-bonded Hot-dip galvanized non-bonded steel strand a hiki ke hoʻopilikino ʻia i nā koi o ka papahana kikoʻī a loaʻa i nā ʻano anawaena, nā ikaika tensile a me ka hoʻopau ʻana i ka ʻili.
I ka hopena, ʻo Hot-dip galvanized unbonded steel strand i mea koʻikoʻi i ke kūkulu ʻana a me nā ʻoihana ʻenekinia e hāʻawi ana i ka ikaika, ka lōʻihi a me ka pale ʻana i ka corrosion. ʻO kā lākou hoʻohana ʻana i nā hale paʻa prestressed a post-tensioned e kōkua i ka hoʻomaikaʻi ʻana i ka palekana, ka lōʻihi a me ka hana ʻana o nā ʻano hana ʻenehana. Me kā lākou versatility a me ka hoʻopau kiʻekiʻe kiʻekiʻe, ke hoʻomau nei kēia mau kaula i ka noi no ka nui o nā noi kūkulu.
