ʻO ke koho o ka mālamaʻana i ka mālamaʻana he pilikia ka maka o nā mea hoʻolālā. Nui nāʻano o ka mana o ka mālamaʻana o ka mālamaʻana, aʻaʻole pono nā mea hoʻokumu nui, e noʻonoʻo wale ka pono o kaʻaha kanaka a me nā koi o kaʻaha honua. Aia ma lalo kahi pōkole pōkole i kekahi mau mea hoʻohana maʻamau i hoʻohanaʻia no nā mea paʻa e pili ana i nā loina ma luna nei, no ka mea e pili ana i nā mea hoʻomaʻamaʻa paʻa.
1.
ʻO Zinc ka mea maʻamau maʻamau i hoʻohanaʻia no nā mea pāʻani kālepa. Hoʻopili hou ke kumu kūʻai,ʻaʻole maikaʻi ka helehelena. Nā kala maʻamau e hoʻopili ai i nāʻulaʻula a me nā pūʻali koa koa. Eia naʻe,ʻo kāna hana anti-corrosion anti-corrosion a me kāna hana anti-corrosion i ka haʻahaʻa ma waena o Zinc. ʻO ka maʻamau, ka hōʻikeʻo kalepaʻo keʻano kamela o Galvanied i loko o 72 mau makahiki, aʻo nāʻenehana kūikawā kūikawā e hoʻohanaʻia e hōʻoiaʻiʻo ai i nāʻoi aku ka nui o ka mea kūʻai. Eia nō naʻe, he kumukūʻai ke kumukūʻai,ʻo ia ka 5-8 mau manawa o ke kila galvalized maʻamau.
ʻO ke kaʻina o ka electrogalvalizing e pili ana i ka hydrogen embrittlement, no lailaʻaʻole i mālamaʻia nā bolts ma luna o ka papa 10.9 ʻOiai e hiki ke laweʻiaʻo Hydrogen i ka hoʻohanaʻana i kahi oven ma hope o ka paleʻana, e hoʻopauʻia ka kiʻi kiʻi ma ka mahana ma lalo o 60. He hana maikaʻiʻole kēia a me nā uku hana kiʻekiʻe. Ma kaʻoiaʻiʻo,ʻaʻole i hana ikaika nā mea kanu maʻamau i ka hydrogen iʻole e hoʻokaʻawaleʻia e nā mea kūʻai kiko'ī.
ʻO ka pono ma waena o ka torque a me ka nui o ka ikaika o nā mea pāʻani galvanized a heʻilihune aʻaʻole maʻamau no ka hoʻopiliʻana i nā'āpana koʻikoʻi. I mea e hoʻomaikaʻi ai i keʻano o ka coristency of torque preload, keʻano o ka coating libricating ma hope o ka hoʻomaikaʻiʻana i ka pale.
2, phoppation
ʻO kahi kumu kumu nui eʻoi aku ka maikaʻi o ka phopshatch ma mua o Galvanizing, akāʻoi aku ka maikaʻi o kona paleʻana ma mua o keʻano o Galvalion. Ma hope o ka phosphating, pono e hoʻopiliʻia ka aila, aʻo kona paleʻana o ke kū'ēʻana e pili pono ana i ka hana o ka aila i hoʻopiliʻia. ʻO ka laʻana, ma hope o ka phoppabing, e noi ana i kahi aila anti anti gust a me ka hanaʻana i kahi hōʻike spet scray spiray spiray no ka 10-20 mau hola wale nō. Ke noi nei i ka hoʻohanaʻana i ka hui anti rusta kiʻekiʻe e hiki ai i ka 72-96 mau hola. Akāʻo kāna kumukūʻai he 2-3 mau manawa o kaʻaila phosophating.
Aia heʻelua mauʻano maʻamau o ka phoppatoring no nā mea pāʻani, zinc e pili ana i ka phoppating a me ka manganene. ʻO Zinc e pili ana i ka photopsing postphating iʻoi aku ka maikaʻi o ka hana ma mua o ka manganese e pili ana i ka phoposing Hiki ke hoʻohanaʻia ma nā mahana mahana mai ka 225 a hiki i 400 degere Fahrenheit (107-204 ℃). Nui no ka pilina o kekahi mau mea nui. E like me ka hoʻopiliʻana i nā koʻokoʻo a me nā nunui o ka mīkini, ke poʻo o ka mīkini, nā bellal
Hoʻohana ka ikaika ikaika kiʻekiʻe i ka phosophating, hiki ke pale aku i nā pilikia hydrogen embrittlement. No laila, nā Bolts ma luna o ka papa 10.9 ma ka mahinaʻoihana maʻamau e hoʻohana maʻamau i ka mālamaʻana i ka hana phoppating.
3.
ʻO Blackening + kaʻailaʻana i ka uhiʻana i nā mea hanaʻoihana no ka meaʻoi aku ka maʻalahi a me nā mea maʻalahi ma mua o kaʻaiʻana. Ma muli o kona blackening,ʻaʻole kokoke ia i ka hikiʻoleʻana i ka pauʻana, no laila, e wikiwiki koke ia me ka aila. ʻOiai i ke alo o ka aila, hiki i ka papa paʻakai paʻakai ke hiki wale i nā hola 3-5.
4.
He kapu maikaʻi nuiʻo Cadmium ʻO ka papaʻainaʻainaʻainaʻaina wai i ke kaʻina o ka uilaʻana i ka cadmium e kiʻekiʻe, aʻo kona kumukūʻai e pili ana i ka 15-20 manawa e hoʻohana ana i ka zinc. No lailaʻaʻole ia i hoʻohanaʻia ma nāʻoihana General, no nā wahi kiko'ī. Hoʻohanaʻia nā mea hana no nā papa hana o ka aila a me nā mokuleleʻo HNA.
5. Chromium i kau
ʻO ka lole chromium ke kūpaʻa loa i ka lewa,ʻaʻole maʻalahi e hoʻololi i ke kala a nalowale i ka luster, a loaʻa i ke kū'ē maikaʻi a me ke kū'ē maikaʻi. ʻO ka hoʻohanaʻana o ka chromium e hoʻolālā ana i nā mea paʻa i hoʻohana pinepineʻia no nā kumu hoʻonaninani. He mea pinepineʻole ia i hoʻohanaʻia ma nā kahuaʻoihana me nā koina o ka corrosioni kiʻekiʻe ʻO ka wā wale nō i lawaʻole ka ikaika o ke kila kila,ʻaʻole i hoʻohanaʻia nā mea paʻa chrome
I mea e pale ai i ka corrosion, pono ke kumukūʻai a me Nickel a ma mua o ka hoʻopiʻiʻana ma mua o ka chrome. Hiki i ka chromium chromium ke hiki i nā kiʻekiʻe kiʻekiʻe o nā mahana kiʻekiʻe o 1200 degere Fahrenheit (650 ℃). Akā aia kekahi pilikia o ka hydrogen embrittlement, like me ka electrogalvalizing.
6. Nickel
Hoʻohana nuiʻia ma nā wahi e koi ai i nā anti-corrosio a me keʻano maikaʻi. No ka laula, ke puka ana o waho o nā pahu kaʻa.

ʻO ka DIP DIP GAP GAPANIZIZIZIZIZing he mea hoʻowalewaleʻo ka mea e hoʻomoʻa i ka zinc i hāpai i kahi wai. ʻO ka mānoanoa o ka lole ma waena o 15 a 100 μ m. Aʻaʻole maʻalahi ia e kāohi, akā, he mau pale kū'ē maikaʻi a hoʻohana pinepineʻia ma kaʻenehana. I ka wā o ka wela welaʻo Pihi Pōpiopio, ua nui ka momona momona, me Zinc maʻamau a me ZINC VAPOR.
Ma muli o ka uhiʻana o ka'ōpala, ua loaʻa iā ia nā pilikia ma ke kaʻeʻana i loko o waho a me waho i nā mea paʻa. Ma muli o keʻano o ka mahana o ke kaʻina hana wela,ʻaʻole hiki ke hoʻohanaʻia no nā mea paʻa ma luna o ka papa 10.9 (340 ~ 500 ℃).
8. Zinc inciltration
ʻO Zinc Intetration kahi mea paʻa paʻa i keʻano o keʻano o keʻano o ka lau o zinc. Maikaʻi konaʻano, a hiki i kahi'āpana lole ke loaʻa i nā kaulaʻelua a me nā lua makapō. ʻO ka mānoanoa e kau ana he 10-110 μ m. A hiki ke hoʻopauʻia ka hala ma 10%. ʻO kāna ikaika a me ka ikaika anti-corrosione hana me ka substrate ka mea maikaʻi loa ma nā kapa komo zinc ʻO ke kaʻina hana hoʻoiliʻana he haumiaʻole a me kaʻoluʻolu a me keʻano o ke kaiāulu.
9. Secromet
ʻAʻohe mea i loaʻa i ka pilikia hydrogen e hoʻopuka nei, aʻo ka hana corque preload consistenty maikaʻi loa. Me kaʻole o ka noʻonoʻoʻana i nā pilikia o ka chromium a me nā kumu kūlohelohe,ʻo Dacrromet ka mea kūpono loa no nā mea kiʻekiʻe kiʻekiʻe me nā koi kiʻekiʻe anti-corrosiod.
