ʻO ka ʻokoʻa ma waena o ka galvanizing electro a me ka galvanizing wela

1. Nā manaʻo like ʻole

ʻO ka galvanizing Hot-dip, ka mea i ʻike ʻia he hot-dip galvanizing a me ka hot-dip galvanizing, kahi ala kūpono o ka metala anti-corrosion, i hoʻohana nui ʻia i nā hale hana metala i nā ʻoihana like ʻole. ʻO ia ka hoʻoheheʻe ʻana i nā ʻāpana kila i hoʻohemo ʻia i loko o kahi hopena zinc hoʻoheheʻe ʻia ma kahi o 500 ° C, i pili ka ʻili o nā ʻāpana kila i ka papa zinc, i mea e hoʻokō ai i ke kumu o ka anti-corrosion.

ʻO Electrogalvanizing, ʻike ʻia hoʻi he galvanizing anuanu ma ka ʻoihana, ʻo ia ke kaʻina hana o ka hoʻohana ʻana i ka electrolysis e hana i kahi ʻano like ʻole, paʻa a paʻa maikaʻi a i ʻole nā ​​​​mea hoʻoheheʻe alloy ma ka ʻili o ka mea hana. Hoʻohālikelike ʻia me nā metala ʻē aʻe, ʻo ka zinc he mea maʻalahi a maʻalahi hoʻi i hoʻopaʻa ʻia. He haʻahaʻa haʻahaʻa haʻahaʻa anti-corrosion coating a hoʻohana nui ʻia e pale i nā ʻāpana kila, ʻoi aku hoʻi i ka corrosion o ka lewa, a no ka hoʻonaninani.

2. He okoa ka hana  

Ke kahe kaʻina hana o ka galvanizing hot-dip: pickling o nā huahana i hoʻopau ʻia - holoi - hoʻohui i ka plating solution - hoʻomaloʻo - rack plating - cooling - lāʻau kemika - hoʻomaʻemaʻe - wili - hoʻopau ʻia ka galvanizing wela.

Electrogalvanizing kaʻina kahe: kemika degreasing - wela ka wai holoi - holoi - electrolytic degreasing - wela ka wai holoi - holoi - ikaika corrosion - holoi - electrogalvanized hao hao - holoi - holoi - malamalama - passivation - holoi - maloʻo.

3. ʻO nā hana hana like ʻole

Nui nā ʻano hana hana no ka galvanizing wela. Ma hope o ka degreasing o ka mea hana, pickling, luʻu, maloʻo, etc., hiki ke hoʻoheheʻe ʻia i loko o ka ʻauʻau zinc hehee. E like me ka hana ʻia ʻana o nā paipu wela wela ma kēia ʻano.

Hoʻopili ʻia ka galvanizing electrolytic e nā mea hana electrolytic. Ma hope o ka degreasing, pickling a me nā kaʻina hana ʻē aʻe, ua hoʻokomo ʻia i loko o kahi hopena i loaʻa ka paʻakai zinc, a hoʻopili ʻia nā mea electrolytic. I ka wā o ka neʻe ʻana o nā au kūpono a maikaʻi ʻole, waiho ʻia kahi papa zinc ma luna o ka mea hana. .

4. Nā hiʻohiʻona likeʻole

ʻOi aku ka ʻinoʻino o ka hiʻohiʻona holoʻokoʻa o ka galvanizing wela, kahi e hoʻopuka ai i nā laina wai kaʻina hana, nā ʻōpū kulu, a me nā mea ʻē aʻe, ʻoi aku ka nui ma kekahi ʻaoʻao o ka mea hana, he keʻokeʻo keʻokeʻo holoʻokoʻa. ʻO ka papa ili o ka electro-galvanizing ka mea maʻalahi, ka nui melemele-'ōmaʻomaʻo, ʻoiaʻiʻo, aia nō hoʻi nā waihoʻoluʻu, uliuli-keʻokeʻo, keʻokeʻo me ke kukui ʻōmaʻomaʻo, a me nā mea ʻē aʻe.
