ʻO ka pā kihi kila galvanized no nā nui maʻamau
GalvanizedʻO ka pā kila kihiUa māhele ʻia ke kila kihi galvanized wela-dip a me ke kila kihi galvanized anu-dip. Ua kapa ʻia hoʻi ke kila kihi galvanized wela-dip a i ʻole ke kila kihi galvanized wela-dip. ʻO ka uhi galvanized anu-dip e hōʻoiaʻiʻo nui i ka pilina piha ma waena o ka pauka zinc a me ke kila ma o ke kumu electrochemical, a hana i kahi ʻokoʻa hiki ke electrode no ka anti-corrosion.
ʻO ke kila kihi galvanized wela-dip ua kapa ʻia hoʻi he kila kihi galvanized wela-dip a i ʻole ke kila kihi galvanized wela-dip. ʻO ia ke hoʻokomo ʻana i ke kila kihi ma hope o ka wehe ʻana i ka popo i loko o ka zinc heheʻe ma kahi o 500 ℃, i hoʻopili ʻia ai ka ʻili o ke kila kihi me kahi papa zinc, i mea e hoʻokō ai i ke kumu o ka anticorrosion, a kūpono ia no nā ʻano ʻino like ʻole e like me ka waikawa ikaika a me ka noe alkali.
Kaʻina hana: kaʻina hana kila kihi galvanized wela-dip: pickling kila kihi → holoi wai → hoʻokomo ʻia i loko o ka plating solvent → hoʻomaloʻo a me ka hoʻomehana mua → rack plating → hoʻoluʻu → passivation → hoʻomaʻemaʻe → wili → hoʻopau ʻia ka galvanizing wela-dip.
Hoʻohana ʻia ke kaʻina hana galvanizing anu e pale i nā metala mai ka pala. No kēia kumu, hoʻohana ʻia kahi uhi o ka mea hoʻopihapiha zinc. Hoʻopili ʻia ia ma ka ʻili e pale ʻia e kekahi ʻano uhi. Ma hope o ka maloʻo ʻana, hana ʻia kahi uhi hoʻopihapiha zinc. I loko o ka uhi maloʻo Loaʻa ka nui o ka zinc (a hiki i ka 95%). Kūpono no ka hana hoʻoponopono (ʻo ia hoʻi i ka wā o ka hana hoʻoponopono, ma kahi wale nō i hōʻino ʻia ai ka ʻili kila i pale ʻia, hiki ke hoʻopili hou ʻia i ka wā e hoʻoponopono ʻia ai ka ʻili). Hoʻohana ʻia ke kaʻina hana galvanizing anu no ka anticorrosion o nā huahana kila a me nā hale like ʻole.
1. Ke kumukūʻai hana haʻahaʻa: ʻoi aku ka haʻahaʻa o ke kumukūʻai o ka galvanizing wela a me ka anti-rust ma mua o nā uhi pena ʻē aʻe;
2. Paʻa a paʻa: hot-dip cʻO ka pā kihi kila arbonLoaʻa iā ia nā ʻano o ka luster ʻili, ka papa zinc like, ʻaʻohe plating nalowale, ʻaʻohe kulu, hoʻopili ikaika a me ke kūpaʻa ikaika i ka corrosion. I ke kaiapuni suburban, hiki ke mālama ʻia ka mānoanoa anti-rust galvanized wela maʻamau ma mua o 50 mau makahiki me ka ʻole o ka hoʻoponopono ʻana; ma nā wahi kūlanakauhale a i ʻole nā wahi kai, hiki ke mālama ʻia ka papa anti-rust galvanized wela maʻamau no 20 mau makahiki me ka ʻole o ka hoʻoponopono ʻana;
3. Hilinaʻi maikaʻi: ʻo ka pilina metallurgical ma waena o ka papa galvanized a me ka mea kila e lilo i ʻāpana o ka ʻili kila, no laila ʻoi aku ka hilinaʻi o ka paʻa o ka uhi ʻana;
4. Ikaika ka paʻakikī o ka uhi ʻana: hana ka papa galvanized i kahi ʻano metallurgical kūikawā, hiki ke kū i ka pōʻino mechanical i ka wā o ka lawe ʻana a me ka hoʻohana ʻana;
5. Palekana piha: hiki ke uhi ʻia kēlā me kēia ʻāpana o nā ʻāpana i uhi ʻia me ka zinc, ʻoiai i loko o nā lua, hiki ke pale piha ʻia nā kihi ʻoi a me nā wahi huna;
6. E mālama i ka manawa a me ka hoʻoikaika: ʻoi aku ka wikiwiki o ke kaʻina hana galvanizing ma mua o nā ʻano hana uhi ʻē aʻe, a hiki ke pale i ka manawa e pono ai no ka pena ʻana ma ke kahua kūkulu ma hope o ke kau ʻana.
ka pā kihi kila galvanizedhoʻohana nui ʻia i nā hale kiaʻi mana, nā hale kiaʻi kamaʻilio, nā mea pā pale, ke kūkulu ʻana i nā papa, nā alahao, ka pale alanui, nā pou kukui alanui, nā ʻāpana moana, nā ʻāpana kūkulu kila, nā hale kōkua substation, ka ʻoihana kukui, a pēlā aku.

1. He aha kāu mau kumukūʻai?
Hiki ke loli kā mākou kumukūʻai ma muli o ka lako a me nā kumu mākeke ʻē aʻe. E hoʻouna aku mākou iā ʻoe i kahi papa inoa kumukūʻai hou ma hope o ka hoʻokaʻaʻike ʻana o kāu ʻoihana
iā mākou no ka ʻike hou aku.
2. Loaʻa iā ʻoe kahi nui kauoha liʻiliʻi loa?
ʻAe, koi mākou i nā kauoha honua āpau e loaʻa kahi nui o ke kauoha liʻiliʻi loa. Inā ʻoe e ʻimi nei e kūʻai hou aku akā ma nā nui liʻiliʻi loa, paipai mākou iā ʻoe e nānā i kā mākou pūnaewele.
3. Hiki iā ʻoe ke hoʻolako i nā palapala pili?
ʻAe, hiki iā mākou ke hāʻawi i ka hapa nui o nā palapala e pili ana i nā Palapala Hōʻoia / Kūlike; ʻInikua; Kumu, a me nā palapala hoʻokuʻu aku ʻē aʻe inā pono.
4. He aha ka awelika o ka manawa alakaʻi?
No nā laʻana, ʻo ka manawa alakaʻi ma kahi o 7 mau lā. No ka hana nui ʻana, ʻo ka manawa alakaʻi he 5-20 mau lā ma hope o ka loaʻa ʻana o ka uku waiho. E lilo nā manawa alakaʻi i mea kūpono i ka wā
(1) ua loaʻa iā mākou kāu waihona, a (2) ua loaʻa iā mākou kāu ʻae hope loa no kāu mau huahana. Inā ʻaʻole kūlike kā mākou mau manawa alakaʻi me kāu lā palena, e ʻoluʻolu e nānā i kāu mau koi me kāu kūʻai aku. I nā hihia āpau e hoʻāʻo mākou e hoʻokō i kāu mau pono. I ka hapa nui o nā hihia hiki iā mākou ke hana pēlā.
5. He aha nā ʻano uku āu e ʻae ai?
30% ma mua e T/T, 70% e uku mua ʻia ma mua o ka hoʻouna ʻana ma FOB; 30% ma mua e T/T, 70% e kūʻē i ke kope o BL kumu ma CIF.
