kaulahao hao hao maikai no kau papahana
ʻO ke kaula hao galvanized ka hopena o ka metala i hoʻoheheʻe ʻia a me ka matrix hao e hana ai i kahi ʻāpana alloy, i hui ʻia ka matrix a me ka uhi.ʻO ke kaulahao hao galvanized ke kaulahao mua no ka pickling, i mea e wehe ai i ka hao oxide ma ka ʻili o ke kaulahao, ma hope o ka pickling, ma o ka ammonium chloride a i ʻole ka zinc chloride aqueous solution a i ʻole ammonium chloride a me ka zinc chloride i hui pū ʻia ka pahu wai wai no ka hoʻomaʻemaʻe, a laila i loko o ka pahu wela wela.Loaʻa i ke kaula hao Galvanized nā mea maikaʻi o ka uhi ʻana i ka lole, ka hoʻopili ikaika a me ke ola lawelawe lōʻihi.
ʻO ke kaula hao galvanized he wela wela i hoʻopaʻa ʻia ma ke kumu o ke kaulahao hao welded (ʻo ia hoʻi, ua hoʻoheheʻe ʻia ka zinc i loko o ka ipu hao, a laila hoʻokomo ʻia ke kaulahao i ka zinc wai no kekahi manawa e lawe i waho, a laila hoʻomaloʻo a maloʻo. ).
ʻO nā paia o loko a me waho o ke kaulahao he papa zinc i hoʻopili ʻia i ka manawa like.Hoʻohana mau ʻia nā kaulahao hao hao no ka lawe ʻana i nā wai kaomi haʻahaʻa (ʻo ia hoʻi ka wai, ke kinoea wai).
ʻO nā ʻano kino o nā kaulahao maʻamau a me nā kaulahao galvanized ua like ia, akā no ka mea ʻokoʻa ka uhi ʻana o ka ʻili, ʻaʻole like like ko lākou pale ʻana.
Hoʻokahi, kaulahao maʻamau: ʻo ka chromium he metala kala kala, paʻa loa ia i ka lewa, ʻoiai ma ka alkali, nitric acid, sulfide, carbonate solution hiki ke mālama i kahi kūlana paʻa.He ʻano paʻakikī ko Chrome, kūpaʻa i ka ʻaʻahu, a hiki ke mālama i kona luster no ka manawa lōʻihi.ʻO ka pōʻino o ka chromium plating ʻaʻole ia e pale i ka metala kumu mai ka pala.No laila, ma mua o ka uhi ʻia ʻana o ke keleawe a i ʻole ke keleawe keleawe e hoʻopaʻa maikaʻi ʻia i ka metala kumu.Ma keʻano laulā, loaʻa i nā kaulahao chrome-plated nā hiʻohiʻona o ke kumukūʻai kiʻekiʻe iki, nā kaʻa kiʻekiʻe kiʻekiʻe o ka home, nā kaʻa lawe lima me ia, ʻaʻole i ʻōlelo ʻia e hoʻohana.
ʻElua, kaulahao galvanized: hiʻohiʻona kaulahao galvanized no ke kala ʻōmaʻomaʻo.ʻO ia ka hopena o ka passivation o ka uhi zinc ma hope o ka bleaching.Hoʻololi liʻiliʻi ka uhi zinc i ka ea maloʻo.I loko o ka ea maʻemaʻe, i loko o ka wai i loaʻa ka carbon dioxide a me ka oxygen, hana kona ʻili i kahi kiʻi ʻoniʻoni o ka zinc carbonate kumu nui.Loaʻa i kēia kiʻiʻoniʻoni ka hopena o ka corrosion inhibition.Hiki ke pale i ka ʻino hou aʻe o ka metala.ʻIke mākou ua loli koke kekahi mau kaulahao galvanized mai ke keʻokeʻo a i ʻulaʻula ma hope o ka hoʻohana ʻana, akā ʻaʻohe loli nui ma hope o kēia, ʻo ia ke kumu.
Hoʻohālikelike ʻia me nā kaulahao maʻamau, nā kaulahao galvanized i ka hana ʻana a me ka hana ʻana ma hope o ka hoʻomaʻamaʻa galvanized kūikawā, i ka hoʻohana ʻana i nā hiʻohiʻona ʻoi aku ka maikaʻi, no laila inā mai ke ola o ka huahana a i ʻole ka hoʻohana maoli ʻana i nā pae o ka hoʻomaikaʻi ʻana.He mea maʻalahi ke kaʻina hana Galvanized, haʻahaʻa ke kumukūʻai, no laila ke ʻano maʻamau, hoʻohana ʻia ke kaʻa paʻa kaumaha me ia.
