Ke kumu o ke anu galvanizing a me ka wela galvanizing okia kukui lāka pale ʻana i ka corrosion a hoʻolōʻihi i ke ola lawelawe o nā kukui alanui lā, no laila he aha ka ʻokoʻa ma waena o nā mea ʻelua?
1. Ka helehelena
ʻO ka hiʻohiʻona o ka galvanizing anuanu he maʻalahi a mālamalama. ʻO ka papa electroplating me ke kaʻina passivation kala he melemele a me ka ʻōmaʻomaʻo, me nā kala ʻehiku. ʻO ka papa electroplating me ke kaʻina passivation keʻokeʻo he keʻokeʻo keʻokeʻo, a he ʻoniʻoni iki i kekahi kihi o ka lā. He mea maʻalahi ka hana ʻana i ka "wela uila" ma nā kihi a me nā ʻaoʻao o ke koʻokoʻo paʻakikī, kahi e ʻoi aku ka mānoanoa o ka papa zinc ma kēia ʻāpana. He mea maʻalahi ke hana i kēia manawa ma ke kihi o loko a hoʻopuka i kahi ʻāpana hina o lalo o kēia manawa, kahi e hoʻoheheʻe ai ka papa zinc ma kēia wahi. ʻAʻole ʻae ʻia ke koʻokoʻo i ka puʻupuʻu zinc a me ka agglomeration.
ʻOi aku ke ʻano o ka galvanizing wela ma mua o ka galvanizing anuanu, a he keʻokeʻo kālā. He mea maʻalahi ka hiʻohiʻona e hana i nā kaha wai kaʻina hana a me nā kulu liʻiliʻi, ʻoi aku hoʻi ma kekahi ʻaoʻao o ke koʻokoʻo.
ʻO ka papa zinc o ka galvanizing wela iki he mau kakini o ka mānoanoa ma mua o ke galvanizing anu, a ʻo kona kūpaʻa corrosion he mau kakini nō hoʻi o ka galvanizing uila, a ʻoi aku ka kiʻekiʻe o kona kumukūʻai ma mua o ke galvanizing anu. Eia nō naʻe, i ka wā lōʻihi, ʻoi aku ka kaulana o ka galvanizing wela me ka pale ʻana i ka ʻōpala ma mua o 10 mau makahiki ma mua o ka galvanizing anuanu me ka pale ʻana i ka ʻōpala no 1-2 mau makahiki wale nō.
2. Kaʻina hana
Cold galvanizing, ʻike ʻia hoʻi he galvanization, ʻo ia ka hoʻohana ʻana i nā mea electrolytic e hoʻokomo i ke koʻokoʻo i loko o ka hopena i loaʻa ka paʻakai zinc ma hope o ka degreasing a me ka pickling, a hoʻohui i ka pole maikaʻi ʻole o nā lako electrolytic. E kau i ka pā zinc ma ka ʻaoʻao ʻē aʻe o ke koʻokoʻo e hoʻopili ai i ka pou maikaʻi o nā mea hana electrolytic, e hoʻopili i ka lako mana, a e hoʻohana i ka neʻe ʻana o ke au mai ka pole maikaʻi a i ka pole maikaʻi ʻole e waiho i kahi papa zinc. ma ka mea hana; ʻO ka galvanizing wela ka wehe ʻana i ka ʻaila, ka holoi waika, ka lāʻau lapaʻau a hoʻomaloʻo i ka mea hana, a laila hoʻoinu iā ia i loko o ka wai hoʻoheheʻe zinc no kekahi manawa, a laila unuhi.
3. Ka hoʻopili ʻana i ka hale
Aia kahi papa o ka brittle compound ma waena o ka uhi a me ka substrate o ka wela galvanizing, akā, ʻaʻohe hopena nui o kēia i kona kūpaʻa corrosion, no ka mea, ʻo kona uhi ʻana he ʻano zinc maʻemaʻe, a ua ʻano like ka uhi ʻana, me ka ʻole o nā pores, ʻaʻole ia. maʻalahi e ʻino; Eia nō naʻe, ʻo ka uhi ʻana o ke galvanizing anu i haku ʻia i kekahi mau zinc atoms, nona ka pili kino. Nui nā pores ma ka ʻili, a ua maʻalahi ke hoʻopili ʻia e ke kaiapuni a me ka corroded.
4. ʻokoʻa ma waena o nā mea ʻelua
Mai nā inoa o nā mea ʻelua, pono mākou e ʻike i ka ʻokoʻa. Loaʻa ka Zinc i loko o nā paipu kila galvanized ma ka lumi wela, aʻo ka zinc i ka galvanizing wela loaʻa ma 450 ℃ ~ 480 ℃.
5. Ka mānoanoa o ka uhi
ʻO ka mānoanoa o ke anu galvanizing coating he 3-5 μm wale nō. ʻOi aku ka maʻalahi o ka hana ʻana, akā ʻaʻole maikaʻi loa kona kūpaʻa corrosion; He 10 μ ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion o ka mānoanoa o ka m a ma luna aʻe, ʻoi aku ka maikaʻi o ka nui o nā manawa o ka pou kukui anu-galvanized.
6. ʻOkoʻa kumu kūʻai
ʻOi aku ka pilikia a me ka koi ʻana o ka galvanizing wela i ka hana ʻana, no laila ke hoʻohana nei kekahi mau ʻoihana me nā lako kahiko a me nā ʻāpana liʻiliʻi i ke ʻano galvanizing anuanu i ka hana ʻana, ʻoi aku ka haʻahaʻa o ke kumukūʻai a me ke kumukūʻai; Eia naʻe,nā mea hana galvanizing hot-dipʻoi aku ka maʻamau a me ke ʻano nui. Loaʻa iā lākou ka mana maikaʻi ma luna o ka maikaʻi a me ke kumukūʻai kiʻekiʻe.
ʻO nā ʻokoʻa ma luna ma waena o ka galvanizing wela a me ka galvanizing anu o nā pou kukui alanui lā e kaʻana like ʻia ma aneʻi. Inā hoʻohana ʻia nā pou kukui alanui o ka lā ma nā wahi kahakai, pono lākou e noʻonoʻo i ke kū ʻana o ka makani a me ke kū ʻana i ka corrosion, ʻaʻole hoʻi e hana i kahi papahana ʻōpala ma muli o ka manaʻo ʻole.
