ʻO nā wili kila i uhi ʻia i ke kala, i ʻike ʻia hoʻi he mau wili kila i uhi ʻia i ke kala, he kuleana koʻikoʻi ia i ka ʻoihana a me ke kūkulu ʻana o kēia wā. Hoʻohana lākou i nā pepa kila galvanized wela, nā pepa kila alumini-zinc wela, nā pepa kila electro-galvanized, a pēlā aku ma ke ʻano he substrates, e hana mua ʻia ana ka ʻili ma mua, me ka hoʻohemo ʻana i ka momona kemika a me ka mālama ʻana i ka hoʻololi kemika, a laila e hoʻopili i hoʻokahi a ʻoi aku paha papa o nā uhi organik ma luna o ka ʻili. ʻO ka hope loa, hoʻomoʻa ʻia a hoʻōla ʻia e hana. No ka mea ua uhi ʻia ka ʻili me nā uhi organik o nā kala like ʻole, ua kapa ʻia nā wili kila kala ma hope o lākou, a ua kapa ʻia ʻo ia he mau wili kila i uhi ʻia i ke kala.
Moʻolelo Hoʻomohala
Ua hoʻomaka ʻia nā pepa kila i uhi ʻia i ke kala ma ʻAmelika Hui Pū ʻIa i ka waena o nā makahiki 1930. I ka wā mua, he mau ʻāpana kila haiki i pena ʻia, i hoʻohana nui ʻia e hana i nā makapō. Me ka hoʻonui ʻia ʻana o ka laulā o ka noi, a me ka hoʻomohala ʻana o ka ʻoihana uhi, nā reagents kemika pretreatment a me ka ʻenehana automation ʻoihana, ua kūkulu ʻia ka ʻāpana uhi ākea mua ma ʻAmelika Hui Pū ʻIa i ka makahiki 1955, a ua hoʻomohala pū ʻia nā uhi mai ka pena resin alkyd mua i nā ʻano me ke kūpaʻa ikaika o ka wā a me nā pigments inorganic. Mai ka makahiki 1960, ua pālahalaha ka ʻenehana i ʻEulopa a me Iapana a ua ulu wikiwiki. ʻO ka mōʻaukala hoʻomohala o nā wili i uhi ʻia i ke kala ma Kina ma kahi o 20 mau makahiki. Ua hoʻolauna ʻia ka laina hana mua e Wuhan Iron and Steel Corporation mai David Company ma UK i Nowemapa 1987. Hoʻohana ia i ke kaʻina hana ʻelua-uhi a me ka ʻelua-baking a me ka ʻenehana pretreatment kemika uhi wili, me kahi hiki ke hana makahiki i hoʻolālā ʻia he 6.4 tons. A laila, ua hoʻokomo ʻia nā lako hana uhi kala o Baosteel i ka hana ʻana i ka makahiki 1988, i hoʻolauna ʻia mai Wean United ma ʻAmelika Hui Pū ʻIa, me ka wikiwiki o ke kaʻina hana he 146 mika i kēlā me kēia minuke a me ka hiki ke hana i kēlā me kēia makahiki he 22 tone. Mai ia manawa, ua hoʻolaʻa nā hale hana kila nui a me nā hale hana pilikino iā lākou iho i ke kūkulu ʻana i nā laina hana i uhi ʻia i ke kala. Ua ulu wikiwiki ka ʻoihana wili i uhi ʻia i ke kala a ua hoʻokumu i kahi kaulahao ʻoihana piha a piha.
Nā Hiʻohiʻona Huahana
1. Hoʻonaninani: He momona a ʻokoʻa nā kala o nā wili i uhi ʻia i ke kala, hiki ke hoʻokō i ka ʻimi ʻana i nā aesthetics i nā ʻoihana like ʻole. Inā he hou a nani a ʻālohilohi paha a hoʻohihi i ka maka, hiki ke hoʻokō maʻalahi ʻia, e hoʻohui ana i ka nani kū hoʻokahi i nā huahana a me nā hale.
2. Ke kūpaʻa ʻana i ka pala: ʻO ka substrate i mālama kūikawā ʻia, me ka pale ʻana o nā uhi organik, he kūpaʻa maikaʻi i ka pala, hiki ke pale aku i ka ʻino ʻana o nā ʻano ʻino, hoʻolōʻihi pono i ke ola lawelawe, a hōʻemi i nā kumukūʻai mālama.
3. Nā waiwai hoʻonohonoho mechanical: Ke hoʻoili nei i ka ikaika mechanical a me nā waiwai maʻalahi e hana i nā papa kila, maʻalahi ke hana a hoʻokomo, hiki ke hoʻololi i nā koi hoʻolālā paʻakikī like ʻole, a he kūpono hoʻi e hana i nā huahana o nā ʻano like ʻole a me nā kikoʻī.
4. Pale ahi: Loaʻa i ka uhi organik ma luna o ka ʻili kekahi pale ahi. Inā he ahi, hiki iā ia ke pale i ka laha ʻana o ke ahi i kekahi ʻano, a laila e hoʻomaikaʻi ai i ka palekana o ka hoʻohana.
ʻAno uhi
1. ʻAno 2/1: Uhi ʻia ka ʻili o luna i ʻelua manawa, uhi ʻia ka ʻili o lalo i hoʻokahi manawa, a hoʻomoʻa ʻia i ʻelua manawa. ʻO ka pena hope hoʻokahi papa o kēia hale he kūpaʻa haʻahaʻa i ka pala a me ke kūʻē ʻana i ke kahakaha, akā maikaʻi ka hoʻopili ʻana, a hoʻohana nui ʻia i nā panela sandwich.
2. ʻAno 2/1M: Uhi ʻia nā ʻili o luna a me lalo i ʻelua manawa a hoʻomoʻa ʻia i hoʻokahi manawa. Loaʻa i ka pena hope ke kūpaʻa maikaʻi i ka pala, ke kūpaʻa i ke kahakaha, nā waiwai hana a me ke kūkulu ʻana, a me ka hoʻopili maikaʻi, a kūpono no nā panela profiled papa hoʻokahi a me nā panela sandwich.
3. ʻAno 2/2: Uhi ʻia nā ʻili o luna a me lalo i ʻelua manawa a hoʻomoʻa ʻia i ʻelua manawa. Loaʻa i ka pena hope pālua ka pale maikaʻi i ka pala, ke kūʻē i ka ʻōpala a me ke ʻano hana. Hoʻohana ʻia ka hapa nui o lākou no nā panela profiled papa hoʻokahi. Eia naʻe, ʻaʻole maikaʻi kona hoʻopili ʻana a ʻaʻole kūpono no nā panela sandwich.
Ka hoʻokaʻawale ʻana a me ka noi ʻana o ka substrate
1. ʻO ka substrate galvanized wela-ʻūlū: loaʻa ka pepa i uhi ʻia i ke kala galvanized wela-ʻūlū ma ka uhi ʻana i ka uhi organik ma luna o ka pepa kila galvanized wela-ʻūlū. Ma waho aʻe o ka hopena pale o ka zinc, ʻo ka uhi organik ma luna o ka ʻili e pāʻani pū kekahi i ka pale ʻana i ka hoʻokaʻawale a me ka pale ʻana i ka popo, a ʻoi aku ka lōʻihi o kona ola lawelawe ma mua o ka pepa galvanized wela-ʻūlū. ʻO ka nui o ka zinc o ka substrate galvanized wela-ʻūlū he 180g/m² (ʻaoʻao pālua), a ʻo ka nui o ka galvanizing o ka substrate galvanized wela-ʻūlū no waho o ka hale he 275g/m². Hoʻohana nui ʻia ia i ke kūkulu ʻana, nā mīkini home, electromechanical, ka halihali a me nā ʻoihana ʻē aʻe.
2. ʻOi aku ke kumukūʻai o ka substrate i uhi ʻia me ka alumina: ʻoi aku ke kumukūʻai ma mua o ka pepa galvanized, me ke kūpaʻa maikaʻi ʻana i ka pala a me ke kūpaʻa wela kiʻekiʻe, hiki iā ia ke pale pono i ka popo ʻoiai i nā wahi ʻino, a ʻo kona ola lawelawe he 2-6 mau manawa o ka pepa galvanized. He kūpono loa ia no ka hoʻohana ʻana i nā wahi waikawa a hoʻohana pinepine ʻia i nā hale a i ʻole nā wahi ʻoihana kūikawā me nā koi lōʻihi kiʻekiʻe.
3. ʻO ka substrate i ʻōwili anu ʻia: like me kahi pā ʻōlohelohe, me ka ʻole o kahi papa pale, me nā koi kiʻekiʻe no ka uhi ʻana, ke kumukūʻai haʻahaʻa loa, ke kaumaha kaumaha loa, kūpono no nā kahua hana mīkini home me nā koi kiʻekiʻe o ka ʻili a me nā wahi pala haʻahaʻa.
4. ʻOi aku ke kumukūʻai o ka substrate Aluminum-magnesium-manganese ma mua o nā mea ma mua, me nā ʻano o ke kaumaha māmā, nani, ʻaʻole maʻalahi ke oxidize, kūpaʻa i ka corrosion, a pēlā aku, kūpono no nā wahi kahakai a i ʻole nā hale ʻoihana me nā koi lōʻihi kiʻekiʻe.
5. ʻO ke kila kila kila: ke kumukūʻai kiʻekiʻe loa, kaumaha kaumaha, ikaika kiʻekiʻe, kūpaʻa wela kiʻekiʻe, kūpaʻa i ka pala, kūpono no ke kaiapuni maʻemaʻe kiʻekiʻe, e like me ke kemika, ka hana ʻana i ka meaʻai a me nā ʻoihana kūikawā ʻē aʻe.
Nā hoʻohana nui
1. ʻOihana kūkulu hale: hoʻohana pinepine ʻia i nā hale kaupaku, nā paia a me nā puka o nā hale ʻoihana a me nā hale kalepa e like me nā hale hana kila, nā kahua mokulele, nā hale kūʻai, nā pahu hau, a me nā mea ʻē aʻe, ʻaʻole hiki ke hāʻawi wale i kahi hiʻohiʻona nani, akā e pale aku hoʻi i ka makani a me ka ua a hoʻolōʻihi i ke ola lawelawe o ka hale. No ka laʻana, hiki i nā hale kaupaku a me nā paia o nā hale kūʻai logistics nui ke hōʻemi i nā kumukūʻai mālama a hoʻonui i ke kiʻi holoʻokoʻa o ka hale me ka hōʻoia ʻana i ka ikaika o ke kūkulu ʻana.
2. ʻOihana lako hale: Hoʻohana nui ʻia ia i ka hana ʻana i nā pahu hau, nā pahu hau, nā mīkini berena, nā lako hale a me nā lako hale ʻē aʻe. ʻO kona mau kala momona a me ke kūpaʻa maikaʻi loa i ka palaho e hoʻohui i ke ʻano a me ka papa i nā lako hale, e hoʻokō ana i nā pono pālua o nā mea kūʻai aku no ka nani a me ka pono.
3. ʻOihana hoʻolaha: Hiki ke hoʻohana ʻia e hana i nā papa hoʻolaha like ʻole, nā keʻena hōʻikeʻike, a me nā mea ʻē aʻe. Me kona mau ʻano nani a paʻa hoʻi, hiki nō iā ia ke mālama i kahi hopena hōʻike maikaʻi i nā wahi waho paʻakikī a huki i ka manaʻo o ka poʻe.
4. ʻOihana halihali: I ka hana ʻana a me ka mālama ʻana i nā kaʻa e like me nā kaʻa, nā kaʻaahi, a me nā moku, hoʻohana ʻia no ka hoʻonaninani a me ka pale ʻana i nā kino kaʻa, nā kaʻa a me nā ʻāpana ʻē aʻe, ʻaʻole wale ia e hoʻomaikaʻi i ke ʻano o nā kaʻa, akā e hoʻoikaika pū i ko lākou kūpaʻa i ka pala.
