Hoʻolauna:
ʻO ka galvanizing wela, i ʻike ʻia ʻo galvanizing, kahi ala kūpono no ka pale ʻana i nā hale metala mai ka ʻino. Hoʻohana nui ʻia i nā ʻoihana like ʻole, pili kēia kaʻina hana i ka hoʻokomo ʻana i nā mea kila i hoʻohemo ʻia i ka lepo i loko o ka zinc hoʻoheheʻe ʻia i nā wela kiʻekiʻe, e hana ana i kahi papa zinc pale ma ka ʻili. Ma kēia moʻomanaʻo, e ʻimi mākou i ke kaʻina hana galvanizing hot-dip, hoʻomālamalama i kāna mau pono, a hāʻawi i nā ʻike i nā ʻano hana like ʻole i hoʻohana ʻia i ka ʻoihana.
ʻO ke Kaʻina Hana Hana Galvanizing Hot-Dip:
ʻO ke kaʻina hana o nā pepa galvanized wela wela ka nui o nā pae, me ka hoʻomākaukau ʻana i ka pā mua, ka hoʻomaʻamaʻa mua ʻana, ka hoʻopaʻa ʻana i ka wela, ka mālama ʻana ma hope o ka uhi ʻana, a me ka nānā ʻana i ka huahana. Ma muli o nā koi kikoʻī, hiki ke hoʻokaʻawale ʻia ke kaʻina hana galvanizing hot-dip i ʻelua mau ala: off-line annealing a me in-line annealing.
1. Hoʻopahemo laina:
Ma kēia ʻano hana, hoʻopaʻa ʻia nā papa kila i ka recrystallization a me ka annealing ma mua o ke komo ʻana i ka laina galvanizing wela. He mea nui e wehe i nā oxides a me ka lepo mai ka ʻili kila ma mua o ka galvanization. Loaʻa kēia ma ka pickling, a ma hope o ka hoʻohana ʻana i kahi zinc chloride a i ʻole ammonium chloride-zinc chloride solvent no ka pale. ʻO ka galvanizing wet-dip galvanizing, ke ʻano kila pepa, a me ka Wheeling hot-dip galvanizing kekahi mau laʻana e hāʻule ana ma lalo o kēia māhele.
2. Hoʻopili i loko o ka laina:
No ka annealing i loko o ka laina, hoʻohana pololei ʻia nā ʻōwili anu a i ʻole nā wili wela e like me ka pā kumu no ka galvanizing wela. Hana ʻia ka hoʻoheheʻe ʻana i ke kinoea i loko o ka laina galvanizing ponoʻī. ʻO ke ala Sendzimir, ke ʻano Sendzimir i hoʻololi ʻia, ke ʻano US Steel Union, ke ʻano Silas, a me ke ʻano Sharon nā ʻenehana kaulana i hoʻohana ʻia no ka annealing in-line.
Nā pōmaikaʻi o Hot-Dip Galvanizing:
1. Uku Uku Hana Haahaa:
Hāʻawi ke kaʻina hana galvanizing wela i nā pono kumukūʻai, ma muli o kona kūpono a me nā mana leo kiʻekiʻe. Me ka manawa pōkole o ka hoʻoponopono ʻana i hoʻohālikelike ʻia me nā ʻano hana pale corrosion ʻē aʻe, hōʻoia kēia kaʻina hana i ka huli wikiwiki a me ka mālama nui ʻana i ka hana a me nā kumu waiwai.
2. lōʻihiKa lōʻihi:
ʻO ka uhi zinc i hoʻokumu ʻia i ka wā o ke kaʻina galvanization e hāʻawi i ka lōʻihi kūʻokoʻa, e hoʻonui i ke ola o nā mea kila. Hāʻawi nā coils galvanized hot-dip i ke kūpaʻa maikaʻi i nā kūlana kaiapuni paʻakikī, me ka corrosion, abrasion, a me ka hopena.
3. Pono pono:
Hoʻohanohano ʻo Hot-dip galvanizing i ka hilinaʻi maikaʻi loa ma muli o ka hoʻohui like ʻana a me ka paʻa mau i hāʻawi ʻia. Mālama kēia ʻano like ʻole i kahi papa o ka zinc ma kēlā me kēia ʻili, ʻaʻohe wahi no nā wahi nāwaliwali hiki ke alakaʻi i ka pala.
4. Paʻa ikaika o ka uhi:
ʻO ka uhi i hana ʻia ma o ka hot-dip galvanizing e hōʻike i ka paʻakikī a me ka maʻalahi. Hoʻopaʻa paʻa ʻia ka papa zinc i ka ʻili kila, e kū pono ana i ka pōʻino mechanical i ka wā o ka lawe ʻana, hoʻokomo ʻana, a me ka lawelawe.
5. Palekana piha:
Hāʻawi ka Hot-dip galvanizing i ka palekana piha i nā mea kila. Hoʻohana ʻia ka zinc coating ma ke ʻano he pale kino e kūʻē i ka corrosion, e pale ana i ke kila o lalo mai ka ʻike ʻana i nā mea corrosive, e like me ka wai a me nā kemika.
6. Mālama manawa a me ka ho'oikaika 'ana:
Ma ka hāʻawi ʻana i ka pale corrosion lōʻihi, hoʻopau nā coils galvanized steel wela i ka pono no ka mālama pinepine ʻana a me ka hoʻoponopono ʻana. ʻO kēia ka unuhi ʻana i ka mālama manawa a me ka hoʻoikaika ʻana no nā ʻoihana e hilinaʻi ana i nā mea kila i uhi ʻia.
Ka hopena:
ʻO ka galvanizing hot-dip he mea nui o ka ʻoihana kila no hoʻokahi haneli. Me kona kumukūʻai-pono, ka lōʻihi, ka hilinaʻi, a me ka pale ākea, ua lilo ia i mea koho maikaʻi loa no ka pale ʻana i ka corrosion. Inā ma o ka annealing off-line a i ʻole in-line annealing, ʻo ke kaʻina hana galvanizing hot-dip e hōʻoia i nā ʻāpana kila e kūpaʻa mau i nā mea kūlohelohe, e hoʻolōʻihi i ko lākou ola a hoʻemi i nā kumukūʻai mālama. Ke hoʻomau nei ka ulu ʻana o nā ʻoihana, ʻo nā pōmaikaʻi o ka hot-dip galvanizing e lilo ia i ʻenehana koʻikoʻi no ka metala anti-corrosion.
