I ka hana maoli ʻana a me ka hana ʻana o Yoke Plates, ʻaʻole no ka aesthetics wale nō ka mālama ʻana i ka ʻili, akā ʻoi aku ka mea nui, ʻo ia ka mea e: hoʻokaʻawale i ka media corrosive, hoʻomaikaʻi i ka ʻaʻahu a me ka pale ʻana i ka hopena, hoʻonui i ke ola o ka lawelawe, hoʻokō i nā koi o ka pale ʻana i ka moana, a hoʻokō i nā palapala hōʻoia maʻamau. Hoʻopili ʻia nā kaʻina hana lapaʻau ʻokoʻa i nā kaiapuni hoʻohana like ʻole, nā kumukūʻai kumukūʻai, a me nā kūlana papahana.
ʻO -hoʻohu wela ke kaʻina hana lapaʻau mua no nā papa ʻauamo. Ma hope o ka hemo ʻana o ka ʻōpala, ua hoʻokomo piha ʻia ka pā ʻauamo, i hana ʻia me ke kila kalapona a i ʻole ke kila -alloy haʻahaʻa, i loko o ka zinc hoʻoheheʻe ʻia i nā wela kiʻekiʻe. Hoʻokumu kēia i ka papa anti-corrosion i hui ʻia ma ka ʻili kila, i loko o kahi papa zinc maʻemaʻe a me kahi ʻāpana zinc-hao. ʻO ia ke ʻano hana lapaʻau i hoʻohana nui ʻia i kēia manawa, -pono, a kūpono hoʻi no ka hoʻohana ʻana i waho no ka wā lōʻihi i waho i nā lako mana a me nā mea hana kila. He 65μm~120μm ka mānoanoa o ka zinc, me ke kaumaha- anti-corrosion coatings a hiki i 150μm{15}} Ma lalo o nā kūlana ma'amau, hiki iā ia ke kū i nā hola 500~1000 o ka ho'ā'o 'ana i ka pa'akai, a ma nā kahakai, 300~500 hola. ʻO nā mea maikaʻi o ka hoʻoheheʻe ʻana i ka wela, ʻo ia hoʻi ka hana anti-corrosion ikaika loa, e hōʻoiaʻiʻo ana i ka hana ʻole o ka ʻōpala no 20~30 mau makahiki ma nā kaiapuni uka. Hāʻawi ʻo ia i ka hoʻopili zinc maikaʻi loa, ka pale ʻana i nā hopena, abrasion, a me ka makani a me ke one erosion, a me ka pale anode kaumaha. ʻOiai me nā ʻōpala kūloko, e pale mau ka zinc i ka substrate kila. He kūpono ia no ka lawe ʻana i ke kai, ʻaʻole i hoʻopilikia ʻia e ka condensation ipu a me nā wahi haʻahaʻa haʻahaʻa, a he ʻano ʻoni kala -hinahina, e kūlike me ke ʻano kuʻuna o nā mea pono mana. He kūpono ia no nā laina uila uila kiʻekiʻe a me ka -kiʻekiʻe kiʻekiʻe, nā ʻauamo hoʻohui makani ma kahakai a me waho, nā pale kiʻi paʻi kiʻi, ka hāpai ʻana a me ka huki ʻana i nā pā hoʻohui, a me ka -wā lōʻihi i waho, ka haʻahaʻa kiʻekiʻe, a me nā kaiapuni haʻahaʻa.
ʻO ka electroplating zinc kahi kaʻina hana e hoʻohana ai i ka electrolysis e waiho i kahi ʻāpana lahilahi o ka zinc ma luna o ka ʻili o ka pā ʻauamo, e hāʻawi ana i ka pale corrosion ʻelua ma o ka pale cathodic a me ka pale kino. ʻO ka mānoanoa o ka zinc layer mai 5μm a 15μm, a kū i nā hoʻokolohua paʻakai no 48 a 96 mau hola. He ʻano keʻokeʻo keʻokeʻo keʻokeʻo a me ke kālā-o ka huahana i ʻoluʻolu a maʻemaʻe. ʻO kona mau mea maikaʻi, ʻo ia ka hiʻohiʻona ʻālohilohi, ʻano like ʻole, nā mea hoʻonani maikaʻi, ka pololei o ka nui, ʻaʻohe deformation mea hana, ʻaʻohe pani o nā lua, ʻaʻohe pono no ka hoʻoponopono hope -a me ke kumu kūʻai haʻahaʻa, kūpono ia no nā huahana haʻahaʻa,-makahiki pōkole.
ʻO ka uhi pauda e pili ana i ka hoʻopili electrostatic o ka pauda plastik ma luna o ka ʻili o ka pā Yoke, a ukali ʻia e -hoʻomaʻamaʻa wela kiʻekiʻe e hana i kahi uhi paʻa. ʻO ka mānoanoa o ka uhi ʻana he 60-120μm, e loaʻa ana i kahi hiʻohiʻona paheʻe me nā mea hoʻonani maikaʻi loa. Hāʻawi ia i kahi hoʻopau ʻaʻahu a nani hoʻi, kūpono no nā pahu mana kūlanakauhale a me nā papahana hoʻolālā ʻāina. He kūpaʻa ia i ka corrosion kemika a me nā ʻakika/alkalis, loaʻa nā waiwai insulation maikaʻi, a hiki ke hoʻohana ʻia no nā ʻāpana hana uila. Loaʻa nā kala like ʻole no ka ʻike maʻalahi. He kūpono ia no nā papahana hoʻolālā ʻāina, nā hale hoʻolāʻau, nā lako o loko, nā pale kiʻi kiʻi kiʻi kiʻi, a me nā ʻāpana koʻikoʻi hiki ʻole i ka lawe ʻana i ke kala.
Hoʻopili ʻia ka wai epoxy, alkyd, a i ʻole ka ʻōpala -pena pale e hana i kahi kiʻiʻoniʻoni pale organik. Hāʻawi ia i ke kūʻokoʻa o ke koho kala, noi maʻalahi, a me ke kumu kūʻai haʻahaʻa. He kūpono no nā ʻāpana pōkole a me ka hoʻohana pōkole -makahiki, kūpono no nā huahana i loko o ka hale me ka pale ʻole i ka ʻino.
No nā papa ʻauamo kila 304/316, ʻo ka pickling a me ka passivation e wehe i ka hao manuahi, e hana ana i kahi kiʻiʻoniʻoni pale chromium oxide -kahi hana i kapa ʻia ʻo passivation. Hoʻomaikaʻi nui kēia i ke kūpaʻa ʻana o ke kila kila i ka paʻakai paʻakai a me ka ʻinoʻino, e loaʻa ana i kahi maʻemaʻe a mālamalama me ka hoʻololi ʻole ʻana i ka pololei o ke ana. ʻO ia ka koho i makemake ʻia no nā kaiapuni kai a me kahakai, kūpono no ka mana makani o waho, nā paepae o waho, nā awa, a me nā wahi ʻoihana kemika.
Hāʻawi nā kaʻina hana lapaʻau ʻili i nā pae like ʻole o ka pale ʻana i ka corrosion. ʻO ka mea maʻamau, ʻo -wela hoʻoheheʻe wela > ka hoʻoheheʻe ʻia ʻana o ke kila kila > ka uhi pauda > electro-galvanizing, a ʻokoʻa hoʻi ko lākou ola lawelawe. No ke kōkua ʻana i nā mea hoʻohana e koho, eia kekahi mau laʻana: No nā kaiapuni waho maʻamau, ʻo ka hot-dip galvanizing ka mea i makemake ʻia ma muli o kona kumu kūʻai kiʻekiʻe-pono, hoʻohana honua, ola lōʻihi, a haʻahaʻa nā kumukūʻai mālama. No ka mana makani o waho, ka mana o ke kai, a me nā kaiapuni paʻakai, ʻo ka passivation ka koho maikaʻi loa, e hāʻawi ana i ka pale ʻana i ka corrosion ikaika loa, ʻaʻole pono e mālama, a me ka hoʻololi ʻana i nā kaiapuni kai loa.
ʻAʻole ʻo ka mālama ʻana i nā papa ʻauamo he "kaʻina pale pale," akā he ʻano ʻenehana koʻikoʻi e hoʻoholo ai i ke ola o ka huahana, ka hoʻololi ʻana i ke kaiapuni, ka palekana o ka papahana, a me ka inoa honua. Kūlike nā kaʻina hana like ʻole i nā hiʻohiʻona hoʻohana like ʻole, nā kumukūʻai kumukūʻai, a me nā kūlana honua. ʻAʻole hiki i ke koho ʻana i ka lāʻau lapaʻau kūpono ke hoʻokō i nā koi pale corrosion akā mālama pū kekahi i nā kumukūʻai, pale i ka ʻōpala i ka wā o ka halihali moana, a hoʻomaikaʻi i ka ʻoluʻolu o nā mea kūʻai aku ma waho.
