Hōʻikeʻike ʻia ʻo Galvanized Square Steel Pipe
Hot dip galvanized square tube mea he kila paipu huahana i undergone kūikawā hana. ʻO kāna kaʻina hana e hoʻokomo i ka paipu square i loko o ka wai zinc molten, e hoʻoulu ai i ka hopena kemika ma waena o ka zinc a me ka ʻili kila, a laila e hana ai i kahi papa paʻa o ka zinc ma ka ʻili o ka paipu kila. ʻO kēia ka ʻike kikoʻī o nā paipu hoʻopaʻa haʻahaʻa hoʻoheheʻe wela wela:
Ma mua o ka mālama ʻana: Pono e ʻohi mua ʻia nā paipu kila no ka wehe ʻana i ka hao oxide a me nā mea haumia ʻē aʻe. A laila, hoʻomaʻemaʻe hou aʻe ma ka hui ʻana i ka ammonium chloride a me ka zinc chloride aqueous solution e hōʻoia i ka maʻemaʻe o ka ʻili o ka paipu kila a ʻaʻohe lepo.
Hoʻohu wela: Hoʻouna ʻia ka paipu kila i hana mua ʻia i loko o kahi pahu hoʻoheheʻe wela, aia ka wai hoʻoheheʻe zinc. E hoʻomoʻa i ka paipu kila i loko o ka hopena zinc no kekahi manawa e hiki ai i ka zinc ke hoʻopili piha me ka ʻili o ke kila, e hana ana i kahi ʻāpana hao zinc.
Hoʻomaʻalili a ma hope o ka mālama ʻana: Lawe ʻia ka paipu kila galvanized mai ka solution zinc a hoʻomaha ʻia. Hiki ke hana ʻia nā hana ʻē aʻe e like me ka hoʻomaʻemaʻe, passivation, a me nā mea ʻē aʻe e hoʻomaikaʻi ai i ka pale ʻana i ka corrosion a me ka maikaʻi o ka ʻili o ka paipu kila.

ʻO Youfa Galvanized Square Steel Pipe Pōmaikaʻi a me nā hoʻohana
Ke kū'ē i ka corrosion ikaika:Hiki i ka papa zinc ma luna o ka ʻili o ka puʻu galvanized square heat-dip ke pale pono i ka corrosion o ke kila e ka oxygen, acidic a me ka wai alkaline, ka paʻakai paʻakai a me nā wahi ʻē aʻe, a laila e hoʻolōʻihi i ke ola lawelawe o ka huahana.
Ka uhi like ʻole:Ma o ke kaʻina hana uhi wela, hiki ke hana ʻia kahi ʻāpana zinc like ʻole ma luna o ka ʻili o ka paipu huinahā e hōʻoia i ka pale ʻana i ka corrosion o ka paipu kila holoʻokoʻa.
Pili ikaika:Hoʻokumu ka papa zinc i kahi paʻa paʻa me ka ʻili kila ma o nā hopena kemika, me ka hoʻopili ikaika a me ke kū'ē ʻana i ka peeling.
ʻO ka hana hana maikaʻi:Hot dip galvanized square tube loaʻa nā waiwai mechanical a me ka hoʻoponopono ʻana, a hiki ke hana ʻia i loko o nā ʻano like ʻole e like me ke kuʻi anu, ka ʻōwili ʻana, ke kaha kiʻi, ke kulou ʻana, a pēlā aku me ka ʻole o ka hōʻino ʻana i ka uhi.
