ʻO ka galvanizing wela, ka mea i ʻike ʻia ʻo ka hot-dip galvanizing a me ka hot-dip galvanizing, kahi ala kūpono o ka pale ʻana i ka corrosion metala, hoʻohana nui ʻia no nā hale metala a me nā mea hana i nā ʻoihana like ʻole.He ʻenehana kaʻina hana e loaʻa ai ka uhi ʻana ma ka hoʻokomo ʻana i ke kila, ke kila kila, ka hao a me nā metala ʻē aʻe i loko o ka metala wai hoʻoheheʻe ʻia a i ʻole ka hao.He ʻano hana lapaʻau i hoʻohana nui ʻia me ka hana maikaʻi a me ke kumukūʻai ma ka honua i kēia lā.ʻO nā huahana galvanized Hot-dip he hana inestimable a hiki ʻole ke hoʻololi ʻia i ka hōʻemi ʻana i ka corrosion a hoʻolōʻihi i ke ola, e mālama i ka ikehu a me nā mea kila.I ka manawa like, ʻo ke kila i uhi ʻia he huahana pōkole me ka waiwai hoʻohui kiʻekiʻe i kākoʻo ʻia a hoʻokumu ʻia e ka mokuʻāina.
Kaʻina hana hana
Hiki ke hoʻokaʻawale ʻia ka hana ʻana a me ka hana ʻana o ka wili kila galvanized i ʻekolu mau ʻanuʻu nui: ʻo ka mua, e ʻoki ʻia ka ʻōwili holoʻokoʻa o ke kila kila no ka wehe ʻana a me ka decontamination e hoʻomaʻemaʻe a maʻemaʻe ka ʻili o ke kila kila;Ma hope o ka pickling, e hoʻomaʻemaʻe ʻia i loko o ka ammonium chloride a i ʻole zinc chloride aqueous solution a i ʻole ammonium chloride a me ka zinc chloride i hui pū ʻia i ka wai wai, a laila hoʻouna ʻia i loko o ka ʻauʻau wela no ka hana galvanizing;Ma hope o ka pau ʻana o ke kaʻina hana galvanizing, hiki ke hoʻopaʻa ʻia a hoʻopaʻa ʻia.

Hoʻomohala mōʻaukala o ka wela galvanizing
Ua hana ʻia ka galvanizing wela i ka waena o ke kenekulia 18.Ua hoʻomohala ʻia mai ke kaʻina hoʻoheheʻe wela wela a ua komo i ke kenekulia ʻehā.A hiki i kēia manawa, ʻoi aku ka nui o ka hoʻohana ʻana i ka galvanizing wela a me ka maikaʻi i ka pale ʻana i ke kila.
I ka makahiki 1742, ua hoʻokō ʻo Kauka Marouin i kahi hoʻokolohua paionia no ka hoʻopaʻa ʻana i ke kila kila a heluhelu ʻia ma ke Kulanui Aliʻi o Farani.
I ka makahiki 1837, ua noi ʻo Sorier o Farani i palapala hōʻailona no ka galvanizing wela a hoʻopuka i ka manaʻo o ka hoʻohana ʻana i ke ala galvanic cell no ka pale ʻana i ke kila, ʻo ia hoʻi, ke kaʻina hana o ka galvanizing a me ka pale ʻana i ka lepo ma ka ili hao.I kēlā makahiki hoʻokahi, ua noi ʻo Crawford o United Kingdom i kahi patent no ka plating zinc me ka hoʻohana ʻana i ka ammonium chloride e like me ka solvent.Ua hahai ʻia kēia ʻano hana a hiki i kēia manawa ma hope o nā hoʻomaikaʻi he nui.
I ka makahiki 1931, ua kūkulu ʻo Sengimir, he ʻenekinia koʻikoʻi i ka ʻoihana metallurgical hou, i ka laina hana hoʻoheheʻe wela hoʻomau mua o ka honua no ka hao hao ma ke ʻano hoʻemi hydrogen ma Polani.Ua hoʻopaʻa ʻia ke ʻano hana ma ʻAmelika Hui Pū ʻIa a me ka laina hana galvanizing wela wela i kapa ʻia ma hope o Sengimir i kūkulu ʻia ma ʻAmelika Hui Pū ʻIa a me Maubuge Iron and Steel Plant ma Farani i 1936-1937, e hana ana i kahi au hou o ka hoʻomau, kiʻekiʻe- ka wikiwiki a me ke kiʻekiʻe kiʻekiʻe hot-dip galvanizing no ka hao hao.
I nā makahiki 1950 a me 1960, ʻo ʻAmelika Hui Pū ʻIa, Iapana, Beretania, Kelemānia, Palani, Kanada a me nā ʻāina ʻē aʻe i hana i nā papa kila aluminized.
I nā makahiki 1970 mua, ua hoʻokumu ʻo Betelehema Iron and Steel Company i ka Al-Zn-Si coating material me ka inoa kālepa Galvalume, nona ka pale corrosion o 2-6 mau manawa ma mua o ka uhi zinc maʻemaʻe.
I ka makahiki 1980, ua hoʻolaha koke ʻia ka huila zinc-nickel wela i ʻEulopa, ʻAmelika a me Australia, a ua kapa ʻia kāna kaʻina hana ʻo Technigalva I kēia manawa, ua hoʻomohala ʻia ʻo Zn-Ni-Si-Bi ma kēia kumu, hiki ke kāohi i ka hopena Sandelin. i ka wā e hoʻopaʻa ʻia ai ke kila silikoni.
I ka makahiki 1990, ua hoʻomohala ʻo Japan Nisin Steel Co., Ltd. i kahi zinc-aluminum-magnesium coating material me ka inoa kālepa o ZAM, nona ka pale ʻana i ka corrosion he 18 mau manawa ma mua o ka hoʻopili zinc maʻamau, i kapa ʻia ʻo ka hā o ka hanauna o ka corrosion kiʻekiʻe. mea pale pale.

Nā hiʻohiʻona huahana
· He ʻoi aku ka maikaʻi o ka corrosion a me ka lōʻihi o ka lawelawe ʻana ma mua o ka pepa anuanu maʻamau;
· Maikaʻi adhesion a weldability;
· Loaʻa nā ʻano ʻano like ʻole: flake nui, flake liʻiliʻi, ʻaʻohe flake;
· Hiki ke hoʻohana ʻia nā lāʻau lapaʻau like ʻole no ka passivation, ka ʻaila, ka hoʻopau ʻana, ka mālama ʻana i ke kaiapuni, etc.
Hoʻohana huahana
Hoʻohana nui ʻia nā huahana galvanized Hot dip ma nā kula he nui.ʻO kā lākou pōmaikaʻi he lōʻihi ko lākou ola anti-corrosion a hiki ke hoʻololi i kahi ākea ākea.He ʻano lapaʻau anti-corrosion kaulana lākou.Hoʻohana nui ʻia ia i ka hale kiaʻi mana, ka hale kiaʻi kamaʻilio, ke kaʻaahi, ka pale alanui, ka pou kukui alanui, nā ʻāpana moana, ke kūkulu ʻana i nā mea hana kila, nā mea kōkua substation, ʻoihana māmā, etc.
