Rol nuil uwea galvanizedhoʻohana nui ʻia i ka hana.He pōʻino nō hoʻi ka uea hao, maʻalahi ka pala a me ka ʻino.No laila, hiki ke hoʻohana maʻamau i ke ala galvanized e pale ai i ka corrosion o nā huahana.Ma waho aʻe o kēia ʻano hana, nā ʻano hana maʻamau i hoʻohana ʻia me ka hoʻomaʻamaʻa phosphating, oxidation lapaʻau, etc. Metal phosphating lapaʻau: hao a me ke kila huahana i ka aila, rust wehe, i loko o ka haku mele 'ana o ka waika solution immersion, hiki ke hana i ka papa o ka insoluble. kiʻiʻoniʻoni ma ka ʻili metala, ua kapa ʻia kēia kaʻina hana phosphating treatment.
ʻōwili nuiuwea galvanizedʻO ke kiʻiʻoniʻoni phosphating he ʻeleʻele hina a ʻeleʻele hina, ʻo ka mānoanoa he 5-20μm, i loko o ka lewa i maikaʻi corrosion kū'ē.He ʻano microporous ka membrane, e like me ka ikaika o ka mana adsorption pena, e like me ka hoʻohana ʻana e like me ka papa lalo o ka pena, hiki ke piʻi i mua ke kūpaʻa corrosion.Metal oxidation lapaʻau: hoʻohui ʻia nā huahana kila i ka hui ʻana o ka NaOH a me NaNO2 solution, ka mālama ʻana i ka wela, hiki i kona ʻili ke hana i kahi papa o ka mānoanoa o kahi 0.5-1.5.μm o ka blue oxide kiʻiʻoniʻoni, i mea e hiki ai i ke kumu o ka pale ʻana i ke kila, ua kapa ʻia kēia kaʻina hana ʻulaʻula, i kapa ʻia he uliuli.
ʻOi aku ka elasticity a me ka lubricity o kēia kiʻi oxide a ʻaʻole pili i ka pololei o nā ʻāpana.No laila, ʻo nā mea kani kikoʻī a me nā ʻāpana mea hana optical, ke kila puna, ka ʻili kila lahilahi, ka uwea kila lahilahi a me nā hana polū maʻamau.ʻO ka ʻōwili nui uea hoʻohana maʻamau i hoʻohana ʻia i ka lāʻau galvanized, ua like ia me ka hana ʻana i kahi papa pale ma ka ʻili o ka uea, hoʻohana mau ʻia.galvanizing wela, ka hoʻoulu ʻana i ka wela, ka hoʻoheheʻe ʻana a me nā ʻano hana ʻē aʻe, loaʻa nā ʻano like ʻole i nā ʻano like.
