ʻO nā mea maikaʻi a me nā pōʻino o ka alumini-zinc plated steel plate

Hoʻohana nui ʻia ke kila kila wela wela i ke kūkulu ʻana, nā mea hana hale a me nā ʻoihana nui ʻē aʻe mai kona ʻike ʻana.Ma muli o ka hoʻonui mau ʻana o ka laulā o ka hoʻohana ʻana, hoʻomaikaʻi mau ʻia ka formability a me nā ʻano ʻano like ʻole o nā huahana i ka pā kila, a ʻoi aku ka maikaʻi o ka alumini-zinc plated plated steel ma mua o ka wela wela i kekahi mau waiwai.ʻO ka pā kila aluminika-zinc
Loaʻa ka Al-Zn composite aluminum-zinc plated steel plate e ka wela-dip plating me ke anuanu-rolled paʻa kila paʻa o nā ʻano ikaika like ʻole a me nā kikoʻī mānoanoa e like me ke kumu kumu.ʻO ka uhi ʻana he 55% aluminika, 43.5% zinc, 1.5% silicon a me nā mea ʻē aʻe.
I ka hana ʻana a me ke kaʻina hana, ʻoi aku ka maikaʻi o ka hana o ka alumini-zinc plating ma mua o ka galvanizing hot-dip, ʻoi aku ka nui ma nā ʻano aʻe.
Hana hana
ʻO ka hana hana o ka alumini-zinc plated steel plate e like me ka hot-dip galvanizing, hiki ke hoʻokō piha i nā koi o ka ʻōwili, stamping, bending a me nā ʻano ʻē aʻe.
ʻO ke kūpaʻa ʻino
Hana ʻia ka hoʻāʻo ʻana ma lalo o ke kumu o ka pale kila wela a me ka pale kila aluminika-zinc me ka mānoanoa like, ka uhi ʻana a me ka mālama ʻana i ka ʻili.ʻO ka alumini-zinc plating he kūpaʻa maikaʻi loa i ka corrosion ma mua o ka wela-dip galvanizing, a ʻo kona ola lawelawe he 2-6 mau manawa ma mua o ka pā kila galvanized maʻamau.
ʻO ka hana hoʻohālike māmā
ʻO ka hiki o ka zinc aluminized e hoʻomālamalama i ka wela a me ka māmā he pālua ia o ka pā kila galvanized, a ʻoi aku ka nui o ka reflectivity ma mua o 0.70, ʻoi aku ka maikaʻi ma mua o 0.65 i kuhikuhi ʻia e EPA Enerav Star.
Kūleʻa wela
Hoʻohana pinepine ʻia nā huahana galvanized wela wela ma kahi mahana ʻaʻole i ʻoi aku ma mua o 230 ℃, a e hoʻololi i ka waihoʻoluʻu ma 250 ℃, ʻoiai hiki ke hoʻohana ʻia ka pā alumini-zinc no ka manawa lōʻihi ma 315 ℃ me ka ʻole o ka hoʻololi ʻana i ke kala.Ma hope o 120 mau hola ma 300 ℃, ʻoi aku ka haʻahaʻa o ka hoʻololi kala o ka pā kila aluminika-zinc i mālama ʻia e ka passivation pale wela ma Baosteel ma mua o ka pā alumini a me ka pā alumini-plated.
waiwai mīkini
Hōʻike nui ʻia nā waiwai mechanical o ka alumini-zinc plated steel plate i ka hoʻoulu ʻana i ka ikaika, ka ikaika tensile a me ka elongation.ʻO ka DC51D galvanized steel plate o 150g / m2 he ikaika hua o 140-300mpa, kahi ikaika tensile o 200-330 a me kahi elongation o 13-25.ʻO ka helu brand DC51D+AZ
ʻO ka ikaika hua o ka aluminized zinc plated steel sheet me 150g / m2 aluminized zinc ma waena o 230-400mpa, ka ikaika tensile ma waena o 230-550, a ʻo ka elongation rail ma waena o 15-45.
No ka mea, he kila kila kiʻekiʻe ka alumini-zinc coating, he nui kona mau pono a me kekahi mau hemahema.
1. Hana wiliwili
Ma muli o ka hoʻonui ʻana o nā waiwai mechanical, maikaʻi ke ʻano o ka uhi ʻana o ka ʻili o ka substrate i loko, a ʻoi aku ka kiʻekiʻe o ka manganese, no laila ʻaʻole hiki ke hoʻopili ʻia ka zinc aluminized ma lalo o nā kūlana welding maʻamau, a hiki ke hoʻopili ʻia e nā rivets a me nā mea ʻē aʻe.Ma keʻano o ka hoʻopiliʻana, hana maikaʻi ka pā kila wela wela, aʻaʻohe pilikia wili.
2. Ke kūpono o ke kaʻa wela pulu
ʻO ka hoʻohui ʻana o ka alumini-zinc coating i loko o ka alumini, kahi mea maʻalahi i ka hopena kemika i ka hoʻopili pololei ʻana me ka ʻakika wai wai.No laila, ʻaʻole kūpono loa ka hana ʻana i nā papa papahele.
