ʻO ka ʻokoʻa ma waena o ka electro-galvanizing a me ka hot-dip galvanizing

ʻO ka ʻili kila i loaʻa i kahi papa galvanized, hiki ke pale i ke kila mai ka ʻōpala i kekahi ʻano.Hoʻokumu ʻia ka papa galvanized o ke kila e ka hot-dip galvanizing a i ʻole electro-galvanizing.No laila he aha nā ʻokoʻa ma waenagalvanizing welaa me ka electro-galvanizing?

Kaʻina Electro Galvanizing

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.Hoʻopili ʻia nā ʻenehana hoʻopaʻa ʻana i ka pahu pahu (a i ʻole ka hoʻopaʻa ʻia ʻana o ka pahu), ka hoʻopaʻa ʻana i ka barela (no nā ʻāpana liʻiliʻi), ka uhi ʻana i ka polū, ka hoʻopaʻa ʻana a me ka hoʻopaʻa mau ʻana (no ka uea, striping).

Nā hiʻohiʻona o ka electro-galvanized

ʻO ke kumu o ka electrogalvanizing ka pale ʻana i nā mea kila mai ka ʻino ʻana, hoʻomaikaʻi i ka pale ʻana i ka corrosion a me ke ola lawelawe o ke kila, a ma ka manawa like e hoʻonui i ka hiʻohiʻona o ka huahana.E ʻino ʻia ke kila, ka wai a i ʻole ka lepo i ka wā.ʻO ke kila i ʻino ʻia i kēlā me kēia makahiki ma Kina, ʻaneʻane ka hapaʻumi o ka nui o ke kila.No laila, i mea e pale ai i ke ola lawelawe o ke kila a i ʻole kona mau ʻāpana, hoʻohana maʻamau ka electro-galvanizing e hana i ke kila.

No ka mea ʻaʻole maʻalahi ka zinc e hoʻololi i ka ea maloʻo, a hiki ke hana i kahi kiʻi ʻoniʻoni zinc carbonate kumu i loko o kahi ʻano haʻahaʻa, hiki i kēia kiʻiʻoniʻoni ke pale aku i nā ʻāpana o loko mai ka pōʻino ʻino, ʻoiai inā ua pōʻino ka papa zinc e kekahi kumu.I kekahi mau hihia, hui pū ka zinc a me ke kila i ka manawa e hana ai i microbattery, me ka pale kila ma ke ʻano he cathode.Hōʻuluʻulu manaʻo Electrogalvanizing i kēia mau hiʻohiʻona:

1. ʻAʻole maʻalahi ke komo ʻana e ke kinoea corrosive a i ʻole ka wai.

2. No ka mea, he maʻemaʻe ka papa zinc, ʻaʻole maʻalahi ke hoʻoheheʻe ʻia i loko o ka ʻakika a i ʻole ka alkali.Mālama pono i ke kino kila no ka manawa lōʻihi.

3. Ma hope o ka passivation e ka chromic acid, hiki ke hoʻohana ʻia i nā kala like ʻole, hiki ke koho ʻia e like me nā makemake o nā mea kūʻai aku.He nani a hoʻonani ka galvanizing.

4. He ductility maikaʻi ka hoʻopili zinc a ʻaʻole e hāʻule maʻalahi i ka wā o ke kulou ʻana, ka lawelawe ʻana a me ka hopena.

He aha ka ʻokoʻa ma waena o ka galvanizing hot-dip a me ka electro-galvanizing

ʻOkoʻa nā loina o nā mea ʻelua.ʻO ka Electrogalvanizing ka hoʻopili ʻana i kahi papa galvanized ma ka ʻili o ke kila ma ke ʻano electrochemical.ʻO ka galvanizing welaʻo ia ka hoʻokomo ʻana i ke kila i loko o kahi ʻano zinc e hana i ka ʻili o ke kila me kahi papa galvanized.

Aia nā ʻokoʻa ma waena o lāua.Inā electro-galvanized ke kila, ʻoi aku ka maʻalahi o kona ʻili.Inā he hao wela ke kila, he ʻeleʻele kona ʻili.ʻO ka nui o nā uhi uila electro-galvanized he 5 a 30μm, a he 30 a 60 ka nui o nā pale galvanized welaμm.

ʻOkoʻa ka laulā o ka noi, hoʻohana nui ʻia ka galvanizing wela i ke kila o waho e like me nā pā alanui, a hoʻohana nui ʻia ka electro-galvanizing i loko o ke kila o loko e like me nā panela.
