Electrogalvanizing VS. Hoʻopaʻa wela wela

Wahi a nā helu helu, maʻalahi ke kila i ka ea, ka wai a i ʻole ka lepo, a ʻo ka poho makahiki i hoʻokumu ʻia e ka corrosion e pili ana i ka 1/10 o ka nui o ka hana kila. I mea e hana ai i ka ʻili o nā mea hoʻopaʻa i kekahi mau hana kūikawā a hāʻawi iā lākou i kahi hiʻohiʻona nani, mālama ʻia lākou e ka electrogalvanizing.

Electrogalvanizing

ʻO ka Electrogalvanizing kahi hana e hoʻopili ai i kahi uhi zinc i ke kila a i ʻole ka hao ma o ka hoʻohana ʻana i kahi au uila. ʻO ke kumumanaʻo ka hoʻokomo ʻana i ka ʻāpana e uhi ʻia i loko o kahi hopena i loaʻa nā ion zinc. Ke hoʻoili ʻia kahi au uila ma ka electrolyte, hoʻemi ʻia nā ion zinc ma ka ʻili o ka cathode, e waiho ana i kahi ʻāpana lahilahi o ka zinc maʻemaʻe. Hiki ke hoʻomalu pono ʻia ka mānoanoa a me ka like ʻole o ka uhi ʻana ma o ka hoʻoponopono ʻana i ka lōʻihi o ke kaʻina hana, ka nui o kēia manawa, a me ke ʻano o ka electrolyte. Hāʻawi kēia ʻano hana i kahi hoʻopau ʻālohilohi, ʻoluʻolu, a me ka nani, me nā uhi maʻamau mai 5 a 30 micrometers.

ʻO nā hiʻohiʻona hana o nā uhi electrogalvanized e pili ana i ka hoʻopili maikaʻi ʻana i ka metala kumu, e hāʻawi ana i ke kūpaʻa corrosion maikaʻi, ʻoi aku ka maikaʻi ma nā wahi ʻino. ʻO ka mānoanoa a me ka mānoanoa i hoʻopaʻa ʻia e hōʻoia i kahi hiʻohiʻona kūlike, i mea kūpono no nā ʻāpana kahi e pono ai ka hoʻopau kiʻekiʻe. Eia nō naʻe, ʻo ka uhi ʻili lahilahi ʻo ia hoʻi, ʻaʻole hiki i ka electrogalvanizing ke hāʻawi i ka pae like o ka pale mechanical e like me ka hot-dip galvanizing, a ʻoi aku ka maʻalahi o ka pōʻino mai ka abrasion a me ka hopena. ʻOiai naʻe, ʻike ʻia ke kaʻina hana no kona hiki ke hana i ka maikaʻi, ʻoiai ka uhi ʻana e hoʻonui ai i ka nānā ʻana o ka huahana i hoʻopau ʻia.

ʻO nā māla e pili ana i ka electrogalvanizing e lilo ana i mea ākea. Ua hoʻolaha ʻia ka noi ʻana o nā huahana fastener i ka hana ʻana i nā mīkini, nā mea uila, nā mea hana pololei, nā kemika, ka lawe ʻana, aerospace, etc.

ʻO ka galvanizing wela

ʻO ka galvanizing Hot-dip kahi kaʻina hana pale corrosion kahi i hoʻomaʻemaʻe ʻia a hoʻomākaukau ʻia nā mea kila a hao paha i loko o ka ʻauʻau o ka zinc hehee ma kahi o 450°C (842°F). Hoʻopili ka zinc me ka hao, e hana ana i nā ʻāpana zinc-iron alloy ma ka ʻili o ka metala, a ukali ʻia e kahi papa o ka zinc maʻemaʻe. Hoʻokumu kēia paʻa metallurgical i ka uhi paʻa paʻa. ʻO ka mānoanoa o ka zinc coating ka mea hoʻoponopono ponoʻī a maʻamau mai 45 a 275 micrometers, ma muli o ka mānoanoa o ka mea kumu. Hiki ke hoʻololi i ka ʻano a me ke ʻano o ka uhi hope ʻana i ka manawa hoʻoluʻu ma hope o ka wehe ʻana mai ka ʻauʻau, e hopena pinepine i kahi ʻano spangled a i ʻole crystalline.

ʻO nā hiʻohiʻona hana o nā uhi galvanized wela ka lōʻihi a me ka pale ʻana i ka corrosion no ka manawa lōʻihi, hiki ke hoʻomau no nā makahiki he ʻumi a me nā wahi paʻakikī. Hāʻawi ka papa zinc mānoanoa i ka pale ikaika i ka pōʻino mechanical, e like me nā ʻōpala a me nā abrasions, a hana ma ke ʻano he anode mōhai, ʻoi aku ka maikaʻi o ka corroding e pale i ke kila lalo. He maikaʻi nō hoʻi ka pale ʻana i ka wela, ʻoiai hiki ke hoʻopili ʻia e nā wela kiʻekiʻe loa. ʻO ka hiʻohiʻona ʻālohilohi, metala hina hina o ka uhi ʻana i ka manawa i kahi patina hina hina, ʻaʻole ia e hoʻololi i kāna mau mea pale. Eia hou, he kumu kūʻai ke kaʻina hana no nā mea nui a kaumaha, no ka mea, hāʻawi ia i kahi hopena lōʻihi e pono ai ka mālama liʻiliʻi.

Hoʻohana nui ʻia ka hot-dip galvanizing i nā noi like ʻole, ʻoi aku ka nui o nā mea e pili ana i nā hale a me nā ʻōnaehana waho, kahi mea nui e ʻike ai i nā mea. Hoʻohana maʻamau ia i ke kila kila, nā alahaka, nā kiaʻi alanui, nā pou pono, a me nā mea hana ʻē aʻe. Ua kaulana nō hoʻi ke ʻano i ka hana ʻana i nā mea mahiʻai, nā mīkini ʻenehana, a me nā ʻōnaehana kaʻa, me nā ala kaʻaahi a me nā pahu lawe. Ma muli o kona hiki ke hāʻawi i kahi hoʻopau ikaika, lōʻihi, a me ka nani, ʻo ka hot-dip galvanizing kahi koho i makemake ʻia no kēlā me kēia noi e koi ana i ka palekana hilinaʻi a lōʻihi mai ka corrosion.

Mahalo iā ʻoe no ka heluhelu ʻana, inā makemake ʻoe e ʻike hou aku i nā mea a mākou e hāʻawi ai hiki iā ʻoe ke hahai i nā loulou ma lalo nei!

E ʻike i nā memo moʻomanaʻo hou mai iā mākou!

E ʻoluʻolu e leka uila iā mākou!
