I mea e hāʻawi aku ai i ka ʻike kuhikuhi hou aku no nā mea hoʻohana e makemake ana e kau i kahi kauoha no nā paipu kila zinc alumini magnesium akā ʻaʻole i kau i kahi kauoha, ua hōʻuluʻulu ka mea hoʻoponopono i kēia ʻatikala me ka manaʻolana e hāʻawi i nā mea kūʻai aku i ka waiwai kuhikuhi hou aku.
ʻIkepili:
I nā makahiki i hala iho nei, ke hoʻonui nei ka nui o ka hana ʻana o ka uhi ʻana o ka home, me nā mea hana me ka hiki ke hana i nā coil wela e hoʻonui nui ana i kā lākou laina huahana i lalo. I loko o ke ʻano o ka hōʻemi ʻana o ke kalapona aupuni a me ka hoʻolaha ʻana i ka ikehu hou, ua lilo nā huahana alumini magnesium galvanized kiʻekiʻe i mea kaulana i nā ʻano like ʻole. I nā makahiki i hala iho nei, ua hui pū nā wili kila i ka hana ʻana o nā coil pepa magnesium zinc alumini, a ua lilo ka hoʻokūkū i mea ikaika loa. E nānā pōkole kēia ʻatikala i ke kūlana hoʻomohala o kēia manawa a me nā manaʻolana o nā coil pepa magnesium zinc alumini home e pili ana i ke kūlana mākeke o kēia manawa.
Hoʻolauna a me ka hoʻokaʻawale ʻana o nā huahana zinc alumini magnesium：
01. Hoʻolauna i nā huahana Zinc Aluminum Magnesium
ʻO ka papa kila alumini magnesium galvanized kahi ʻano hou o ka papa kila i uhi ʻia me ke kūpaʻa kiʻekiʻe i ka corrosion, i haku ʻia me ka zinc, 1.5% -11% alumini, 1.5% -3% magnesium, a me nā ʻāpana liʻiliʻi o ka silicon (me nā ʻokoʻa iki ma waena o nā mea hana like ʻole). Hoʻohana nui ʻia ia no ka mālama ʻana i ka ʻili o nā huahana kila a me ke kila, me nā ʻano uhi zinc moʻo like ʻole a me ka nui o nā ʻāpana kila holoʻokoʻa no ka pale ʻana i ka corrosion immersion. Me ka hoʻomohala mau ʻana o ka ʻenehana, hoʻohana nui ʻia nā papa kila i uhi ʻia me ka zinc alumini magnesium alloy i ka ʻoihana kūkulu ma muli o ko lākou kūpaʻa maikaʻi loa i ka corrosion, ka maikaʻi o ke ʻano, ka weldability, a me ke ʻano hoʻonaninani. Ke hoʻolaha mālie ʻia nei lākou a hoʻopili ʻia i nā ʻoihana e like me nā mīkini home a me ka hana kaʻa.
Ua hoʻomaka ʻo Nippon Steel, Nippon Steel, ThyssenKrupp a me nā ʻoihana kila kaulana ʻē aʻe o ka honua e aʻo i kēia papa kila i nā makahiki 1980, a ua ʻike i ka hana ʻoihana a me ka hoʻohana ʻana i ka hoʻomaka ʻana o ke kenekulia 21. ʻEhā mau makahiki i hala aku nei, ua lawe ʻia mai ka hapa nui o nā huahana zinc alumini magnesium i hoʻohana ʻia ma Kina mai nā ʻāina e like me Iapana a me Kōlea Hema. Me ka hoʻomau ʻana o ka fermentation o ka ʻoihana photovoltaic i nā makahiki i hala iho nei, me nā hale wili kila aupuni e like me Baosteel, Jiuquan Steel, Shougang, a me Tangshan Steel, ua komo pū kekahi nui o nā hale wili kila pilikino i ka ʻoihana, e like me Tianjin Xinyu lāua ʻo Hebei Zhaojian. Ua komo pū kekahi mau ʻoihana hana kila ʻāpana i ka ʻoihana. I kēia manawa, ʻo ka laulā mānoanoa e hiki ke hana ʻia ma Kina he 0.4mm-4.0mm, a ʻo ka laulā ākea e hiki ke hana ʻia he 580mm-2080mm. I kēia manawa, ʻo nā wili kila ma Kina e hana ana i nā ʻōwili pepa zinc alumini magnesium he haʻahaʻa alumini zinc alumini magnesium, a he kakaikahi wale nō nā ʻoihana e hiki ke hana i ka alumini zinc alumini magnesium waena (kiʻekiʻe). No ka laʻana, loaʻa iā Shougang kahi moʻo piha o ka zinc alumini magnesium, a ʻo ia wale nō ka laina hana ma ka ʻāina e hiki ke hāʻawi i nā papa kila i uhi ʻia me ka zinc alumini magnesium me ka mānoanoa o 3.0 mm a ʻoi aku paha no nā kumu kūkulu.
02. Ka Hoʻokaʻawale ʻana a me nā ʻAno Huahana o nā Huahana Zinc Aluminum Magnesium
I kēia manawa, e like me ka loiloi a China Baowu o nā papa kila i uhi ʻia i ka magnesium kalepa, ʻo ka hapa nui o nā uhi i loaʻa ka magnesium a me ka magnesium ≤ 3%. Ma muli o ka ʻokoʻa o ka ʻike alumini i loko o nā uhi, ua māhele ʻia nā uhi zinc alumini magnesium i:
Uhi alumini zinc alumini magnesium haʻahaʻa: ʻO ka nui o ka alumini: 1% -3.5%. Hoʻokumu ʻia kēia uhi ma ka hoʻohui ʻana i kahi nui o ka alumini magnesium a me nā mea ʻē aʻe ma ke kumu o ka galvanizing wela-dip. ʻO kēia uhi he mana hou aʻe ia o ke kūpaʻa ʻana i ka corrosion o ka uhi zinc maʻemaʻe wela-dip.
ʻO ka uhi alumini zinc alumini magnesium waena: ka nui o ka alumini: 5% -11%.
Uhi alumini zinc alumini magnesium kiʻekiʻe: ʻO ka nui o ka alumini: 55%. Hoʻokumu ʻia kēia uhi ma ka hoʻohui ʻana i kahi nui o ka magnesium a me nā mea ʻē aʻe ma ke kumu o ka uhi alumini zinc wela. ʻO kēia uhi he mana hou aʻe ia o ke kūpaʻa ʻana i ka palaho o ka uhi alumini zinc wela.
I kēia manawa, ʻo ka hana nui ma Kina ka magnesium alumini zinc haʻahaʻa, a hiki i kekahi mau ʻoihana e like me Shougang lāua ʻo Baosteel ke hana i ka magnesium alumini zinc kiʻekiʻe. ʻAʻole hiki ke hana pololei ʻia ka magnesium alumini zinc, akā lawelawe pū kekahi ma ke ʻano he substrate no nā ʻōwili pepa i uhi ʻia i ke kala. I ka hoʻomaka ʻana o 2022, ua hoʻokuʻu kūhelu ʻia ka ʻōwili mua o ka uhi kala o Baosteel Zhanjiang Steel a ua hoʻomaka ka hana nui ʻana i ka hopena o Pepeluali. Hiki i ka uhi kala o Baosteel Zhanjiang Steel ke hoʻohana i kahi laulā piha o ka magnesium alumini zinc ma ke ʻano he substrate, e lilo ia i kumu hana honua wale nō no kahi laulā piha o nā uhi kala magnesium alumini zinc.
Ua lilo ke ʻano o nā huahana zinc aluminum magnesium i kumuhana wela i kēia manawa, pili loa i ko lākou ʻano huahana maikaʻi. ʻO ka pōmaikaʻi nui o ka maikaʻi o nā huahana uhi zinc aluminum magnesium e hōʻike ʻia ana i ke kūpaʻa kiʻekiʻe o ka corrosion, a ukali ʻia e ka hana hana.
Papa 1: Hoʻohālikelike ma waena o nā huahana Zinc Aluminum Magnesium a me nā huahana Zinc Maʻemaʻe
| Helu | Nā ʻano huahana | Hoʻohālikelike ma waena o Zinc Aluminum Magnesium a me Pure Zinc |
| 1 | Ke kūpaʻa ʻana i ka palaho pālahalaha | Hoʻāʻo pīpī paʻakai kūlike ʻole: ʻOi aku ka kiʻekiʻe o ka uhi zinc alumini magnesium ma mua o ka uhi zinc maʻemaʻe kuʻuna. ʻO ka pala lōʻihi o ka lewa: Hiki i ka uhi zinc alumini magnesium ke piʻi aʻe ma mua o 2 mau manawa ma mua o ka uhi zinc maʻemaʻe. |

| 3 | Ka helu haʻalulu haʻahaʻa | ʻO ke koina friction o ka uhi zinc alumini magnesium he 15% haʻahaʻa ma mua o ka uhi zinc maʻemaʻe |
| 4 | ke kūpaʻa ʻana i ke komo ʻana | ʻO ka paʻakikī o ka uhi zinc alumini magnesium ma kahi o ʻekolu manawa o ka uhi zinc maʻemaʻe |
Ka ʻikepili hoʻomohala holoʻokoʻa o nā huahana zinc alumini magnesium kūloko
01. Hoʻomohala ʻokoʻa iki o ka hiki ke hana i ka uhi ʻana
E like me ka mea i ʻōlelo ʻia ma ka hoʻomaka ʻana o ka ʻatikala ma luna, ma mua o 2016, ua hakahaka nā huahana magnesium alumini galvanized kūloko. Me kekahi mau ʻoihana kikowaena, nā ʻoihana aupuni, a me nā ʻoihana uhi pilikino nui e komo mālie ana i ka mākeke kūloko, ke ulu mālie nei ka hiki ke hana o ka zinc alumini magnesium. Wahi a nā helu helu piha ʻole, manaʻo ʻia ka hiki ke hana o ka zinc alumini magnesium ma kahi o 7 miliona tons i kēlā me kēia makahiki, a aia ka huahana o kēia manawa i kahi pae o ka ulu wikiwiki. Eia nō naʻe, i loko o ke ʻano o ka hana kila nui a China Steel a me ka hiki ke uhi ʻia ma mua o 160 miliona tons, ua liʻiliʻi ka hapa holoʻokoʻa o ka uhi zinc alumini magnesium.
ʻO ka hoʻomohala mālie ʻana o nā huahana hou e hōʻike ana i ka nui o ka hiki ke hana o ka ʻoihana uhi holoʻokoʻa: ʻoiai he nui ka hiki ke hana uhi o Kina, ʻo ka nui o ka hoʻohana ʻana o ka hiki ke hana maoli ma lalo o 60%, a ʻaʻole lawa nā ʻoihana pilikino ma ke ʻano o ke kūkulu ʻana a me ka hoʻohana maoli. He kiʻekiʻe nā pilikia loea a me nā koi hana o nā huahana alumini magnesium galvanized, a me ka waiwai mākeke maikaʻi a me nā manaʻolana, a ua lilo i kuhikuhi wela no ka noiʻi a me ka hana ʻana ma ka ʻoihana like ma ka home a ma waho.
02. Ma lalo o ka hoʻokūkū ikaika, aia nō kekahi hiki ke loaʻa kālā no nā huahana hou
Kiʻi 1: Ke ʻano o ke kumukūʻai a me ka ʻokoʻa o ke kumukūʻai ma waena o ka zinc, alumini, magnesium, a me ka zinc plating ma Shanghai (ʻāpana: yuan/ton)
Ma ka lā 7 o Dekemaba, ʻo ke kumukūʻai o ka Mysteel's mainstream specification 2.0mm Ansteel zinc aluminum magnesium sheet coil ma ka mākeke Shanghai he 5500 yuan/ton, ʻoiai ʻo ke kumukūʻai o ka huahana galvanized mainstream 1.0mm Ansteel galvanized sheet coil he 4700 yuan/ton, a ʻo ka ʻokoʻa kumukūʻai ma waena o ka zinc aluminum magnesium sheet coil a me ka galvanized sheet coil he 800 yuan/ton. Wahi a ka helu ʻana o ka papa zinc a me ka markup kikoʻī ma ka hale hana kila, ʻo ka zinc aluminum magnesium plate coil he 275g zinc layer, a ʻo ka markup no ka papa zinc ma ka hale hana kila ma kahi o 300 yuan/ton. Ma muli o kēia helu ʻana, ʻoiai no nā huahana me ka mānoanoa o ka papa zinc like, ʻoi aku ke kiʻekiʻe o ke kumukūʻai o ka zinc aluminum magnesium ma mua o nā galvanized sheet coils, kahi e hōʻike pololei ʻole ai aia nō kahi hiki ke loaʻa kālā no nā huahana zinc aluminum magnesium, inā paha mai ka manaʻo o nā mea kālepa a i ʻole nā hale wili kila. ʻOiaʻiʻo, he mea kūpono ke hoʻomaopopo ʻana i Iulai, ua piʻi ka ʻokoʻa o ke kumukūʻai ma waena o ka zinc aluminum magnesium a me ka galvanized sheet coil i 1350 yuan/ton, a laila noho mau i loko o 1000 yuan/ton, e hōʻike ana aia kekahi hoʻokūkū ma ka mākeke zinc aluminum magnesium o kēia manawa. ʻO ka ʻokoʻa o ke kumukūʻai ma waena o Tianjin zinc aluminum magnesium a me ka galvanized sheet he laʻana maikaʻi ia, e like me ka mea i hōʻike ʻia ma ke Kiʻi 2.
Ma ka mākeke mea kūʻai aku photovoltaic, ma waho aʻe o ka mākeke Hikina Kina, aia kekahi mākeke i hoʻopaʻa ʻia, ʻo Tianjin, i hoʻopaʻa nui ʻia ma Daqiuzhuang. Ua lilo kēia wahi hana i hoʻopaʻa ʻia o nā brackets photovoltaic i pahuhopu koʻikoʻi no nā hale wili kila he nui. I kēia manawa, ma ka mākeke Tianjin, ʻo nā kumuwaiwai wili kila nui e kaʻapuni ana e komo pū ana me nā hale wili kila aupuni ʻo Shougang, Ansteel, Tangshan Steel, a me Handan Steel; ʻO nā hale wili kila pilikino e like me Hebei Zhaojian, Tianjin Xinyu, Shandong Huafeng, a pēlā aku. Mai ka manaʻo o ka hoʻohālikelike ʻokoʻa kumukūʻai, ʻoi aku ka haʻahaʻa o ka ʻokoʻa kumukūʻai ma waena o Tianjin zinc aluminum magnesium a me ka zinc plating ma mua o ka mākeke Shanghai. I mea e hopu ai i ka māhele mākeke, ua hoʻoponopono pū nā hale wili kila i kā lākou mau kulekele.
03 Ka wikiwiki o ka hoʻomohala ʻana o ka ʻoihana photovoltaic ma ke ʻano o ka ikehu hou a me ke kaiapuni hōʻemi kalapona
Ke hōʻike nei ka ʻoihana ma lalo o ka ʻoihana uhi kūloko i kahi ʻano ʻokoʻa, a ua hala ke kahua ulu wela o ka hoʻohana ʻana i nā kaʻa a me nā lako hale, akā ke ulu wikiwiki nei ka ikehu hou. Ma Nowemapa 21, ua hoʻokuʻu ka National Passenger Car Information Joint Conference i kahi hōʻike e pili ana i ke ʻano o ka mākeke kaʻa ikehu hou o Kina: ʻo ka hana ʻana o nā kaʻa ikehu hou o Kina mai Ianuali a ʻOkakopa he 5.59 miliona mau ʻāpana, he piʻi makahiki-ma-makahiki o 108.4%, me ka helu komo hōʻuluʻulu o 24.7% a me ka helu hāʻawi ma luna o 80% i ka ulu ʻana o ka mākeke kaʻa. Pēlā nō, ma ke ʻano o ka ʻāina e hoʻolaha ikaika nei i nā ʻōnaehana hou a me ka hoʻohana ʻana i ka ikehu hou, ʻo ke koi hoʻohana o ka ʻoihana zinc alumini magnesium he wahi ulu a me ka ikaika pahū.
Ua hōʻea ka ʻoihana photovoltaic o Kina i nā pae alakaʻi honua ma nā ʻano like ʻole, ʻoi aku hoʻi mai ka makahiki 2022, ma lalo o ke kaomi o nā maʻi ahulau pinepine o COVID-19 a me ka emi ʻana o ka hoʻokele waiwai, ua paʻa ka ikaika o ka hoʻomohala holoʻokoʻa o ka ʻoihana photovoltaic. I nā hapaha ʻekolu mua o 2022, ua holomua nui ka hana ʻana o Kina i ka silicon polycrystalline, nā wafers silicon, nā pila, a me nā ʻāpana, a ua hōʻea ka hana ʻana o nā loulou like ʻole i loko o ke kaulahao ʻoihana i kahi kiʻekiʻe mōʻaukala. Ke hoʻomau nei ka ʻenehana ʻoihana i ka hana hou a me ka holomua, a ua hoʻonohonoho ka pono hoʻololi o nā cell solar silicon heterojunction i kahi moʻolelo honua hou o 26.81%. Ua hana ʻia nā holomua hou i ka noiʻi a me ka hoʻomohala ʻana a me ka hoʻāʻo hoʻāʻo o nā cell perovskite stacked, a ke hoʻonui mau nei ke kumu hoʻohālike "photovoltaic+". I nā hapaha ʻekolu mua, ua hōʻea ka mana hou i hoʻokomo ʻia o nā photovoltaics kūloko i 52.6GW. Mai Ianuali a ʻOkakopa, ua ʻoi aku ka nui o ka waiwai hoʻokuʻu aku o nā photovoltaics ma Kina ma mua o 44 biliona kālā US, e kākoʻo ikaika ana i ka ulu ʻana o ke koi o nā mākeke photovoltaics kūloko a me nā haole.
Ka Nānā ʻana i nā Manaʻolana Hoʻomohala o ka Zinc Aluminum Magnesium Sheet and Roll
01 Ke hoʻomaikaʻi mau nei i nā kūlana huahana ma nā kahua noi ʻoihana
I ke kua o ka ulu wikiwiki ʻana o ka hiki ke hana i nā uhi uhi holoʻokoʻa, aia nō ke kūlana o ka hiki ke hana i nā uhi uhi kiʻekiʻe me ka helu hoʻohana haʻahaʻa. E hoʻomau nā ʻoihana i ka hoʻonui ʻana i nā kahawai kūʻai aku mākeke a hoʻonui i ka māhele mākeke. No ka hoʻonui mau ʻana o nā laminates i uhi ʻia iā lākou iho, hiki ke hoʻomaopopo ʻia, akā i ka hoʻokūkū mau o ka ʻoihana, aia kekahi ʻano o ka pani ʻana ma waena o ka laulā o nā laminates i uhi ʻia a me nā ʻōwili.
Ma ke kahua o ka ʻoihana huahana alumini magnesium galvanized, i ka nele o nā kūlana huahana i kēia manawa, he mea nui ia no nā ʻoihana nui o ka mokuʻāina ma Kina e alakaʻi i ka hoʻokumu ʻana i nā kūlana pili. I mea e hoʻohālikelike ai i ka hoʻomohala ʻana a me ka hana ʻana o ka zinc aluminum magnesium, kahi huahana hou, ma ke ala olakino, ua hoʻonohonoho ka loea kaulana ʻo Polofesa Xu Xiufei mai China Metallurgical Corporation (MCC), me ke kākoʻo a me ke kōkua o ke Komite Kūlana Kila Lahui, i nā ʻoihana uhi maikaʻi loa ma ka ʻāina e hoʻoponopono hou i ke kūlana ʻoihana o "Continuous Hot Dip Coated Steel Plate and Strip for Construction". No ka manawa mua ma ka honua, ua hoʻokomo ʻia nā ʻāpana uhi āpau, me ʻekolu mau māhele nui o ka zinc aluminum magnesium, i loko o ke kūlana like, ʻaʻole wale ia he mea maʻalahi no nā mea kūʻai e hoʻohālikelike a hoʻohana, hiki iā ia ke hoʻolaha i ke koho kūpono o nā mea a me nā huahana plating kiʻekiʻe a me ke kumukūʻai kūpono.
Me ka hoʻomaikaʻi ʻana o ka hoʻokūkū o nā huahana zinc alumini magnesium o nā ʻoihana kūloko, ua hoʻohuli ʻia ke ʻano o ka lawe ʻana mai i nā huahana zinc alumini magnesium mai nā ʻāina ʻē, a ua hoʻokuʻu ʻia aku ka nui o nā huahana kiʻekiʻe i nā ʻāina holomua e like me ʻEulopa a me ʻAmelika. Ma muli o ka nele o nā kūlana honua, ʻaʻole ia i keakea wale i ke kālepa lawe mai a me ka hoʻokuʻu aku i nā huahana kila zinc alumini magnesium, akā ua hoʻopilikia pū i nā pale loea o ka ʻoihana. No laila, ʻo ka hoʻoikaika ʻana no ke kūkākūkā honua a me ka hoʻokumu ʻana i nā kūlana honua ua lilo i ana nui no nā huahana Kina e hele i ka honua. Hiki ke manaʻo ʻia e wehe ka hoʻolaha ʻana o ka papahana kūlana honua no nā pepa zinc alumini magnesium i kahi kūlana hou no nā ʻoihana pepa i uhi ʻia Kina e hoʻokūkū ma ke kahua honua.
02 He mea kūpono ke kakali i ka hoʻomohala ʻana o ka huahana i ka wā e hiki mai ana
ʻAʻole hiki ke hoʻonui ʻia ke kaomi e kū nei i ka ʻoihana pepa i uhi ʻia a me ka ʻōwili. He koʻikoʻi nō ka nui o ka hiki ke hana, a he lohi nō hoʻi ke kikowaena kumukūʻai. E hoʻomau ka lohi o ka ulu ʻana o ka hana ʻoihana kūloko e like me nā mīkini home a me nā kaʻa, e paʻakikī ai ka hoʻonui ʻana i ke koi. Eia kekahi, ke hoʻomau nei ka emi ʻana o ka loaʻa kālā o ka ʻoihana pepa metala, me nā huahana i uhi ʻia, a e hoʻomau ka hoʻoponopono ʻana i ke kūkulu kūloko e hoʻonui i ka hoʻololi hou ʻana o ka ʻoihana.
Eia nō naʻe, he mau hana huahana kūikawā a me nā ʻano noi nā huahana alumini magnesium galvanized e pili ana i nā huahana uhi, a kiʻekiʻe mau ka paepae loea ma ka home a me nā ʻāina ʻē. I ka manawa like, ke ulu nei kona hoʻohana ʻana i nā papahana koʻikoʻi a me nā ʻoihana mea kūʻai aku ma lalo o ke kahua kiʻekiʻe, a ke hoʻonui mau nei kona mau wahi hoʻohana. He mea kūpono ke nānā aku i nā manaʻolana hoʻomohala e hiki mai ana. Inā hiki i kekahi ke komo i ka papa inoa keʻokeʻo o nā ʻoihana kūʻai, e loaʻa iā lākou kahi pono kūikawā i kēia hoʻokūkū.
Ua hoʻoikaika mālie ʻia ka hoʻokūkū mākeke o kēia manawa no ka alumini zinc alumini magnesium haʻahaʻa, a ke komo nei nā ʻoihana hou aʻe i ka hana ʻana a me ke kūʻai aku ʻana i nā huahana zinc alumini magnesium i mea e kaʻana like ai i ka mahele huahana. Ma muli o nā ʻano o ka mea kūʻai aku a me nā ʻano hoʻomohala ʻoihana, ua ʻōlelo ʻia e hoʻonohonoho i ke kūlana o nā huahana alumini magnesium galvanized ma ke ala (waena) alumini zinc alumini magnesium kiʻekiʻe. ʻO ka mākeke mālamalama a me ka palena waiwai nui o ka ʻoihana ka mea a nā mea a pau e kakali nei.
