He aha nā mea maikaʻi o nā huahana zinc-aluminum-magnesium?

1. Kū'ē i ka'ōpala o ka uhi
ʻO ka ʻinoʻino o ka ʻili o nā lau i uhi pinepine ʻia i nā ʻōpala. ʻAʻole hiki ke pale ʻia nā ʻōpala, ʻoi aku ka maikaʻi i ka wā e hana ai. Inā loaʻa i ka pepa i uhi ʻia nā waiwai kūʻokoʻa ikaika, hiki iā ia ke hōʻemi nui i ka pōʻino, a laila e hoʻolōʻihi i kona ola. Hōʻike nā hoʻokolohuaNā pepa ZAMʻoi aku ka maikaʻi ma mua o nā mea ʻē aʻe; Hōʻike lākou i ka pale ʻana ma lalo o nā ukana ʻoi aku ma mua o 1.5 mau manawa o ka alumini galvanized-5% a ʻoi aku i ʻekolu mau manawa o nā pepa galvanized a me ka zinc-aluminum. ʻO kēia kūlana kiʻekiʻe mai ka paʻakikī kiʻekiʻe o kā lākou uhi.

2. Weldability
Ke hoʻohālikelike ʻia me nā ʻili wela a me nā ʻili anu,ZAMHōʻike nā papa i ka haʻahaʻa haʻahaʻa o ka weldability. Eia nō naʻe, me nā ʻenehana kūpono, hiki ke hoʻopaʻa ʻia me ka maikaʻi, mālama i ka ikaika a me ka hana. No nā wahi wili, hoʻoponopono me nā ʻano ʻano Zn-Al hiki ke loaʻa nā hopena e like me ka uhi mua.

3. Hiki ke pena
Ua like ka pena pena o ZAM me ka galvanized-5% alumini a me ka zinc-aluminum-silicon coatings. Hiki iā ia ke hana i ka pena kiʻi, hoʻonui hou i ka helehelena a me ka lōʻihi.

4. Hoʻololi ʻole
Aia nā hiʻohiʻona kikoʻī kahi hiki ʻole ke hoʻololi ʻia ka zinc-aluminum-magnesium e nā huahana ʻē aʻe:
(1) Ma nā noi waho e koi ana i nā kikoʻī mānoanoa a me nā uhi ʻili ikaika, e like me nā pale alaloa, i hilinaʻi mua ʻia i ka galvanization nui. Me ka hiki ʻana mai o ka zinc-aluminum-magnesium, ua hiki ke hoʻomau i ka galvanization hot-dip. Loaʻa nā huahana e like me ke kākoʻo o ka lā a me nā ʻāpana alahaka mai kēia holomua.
(2) Ma nā wahi e like me ʻEulopa, kahi e laha ʻia ai ka paʻakai alanui, me ka hoʻohana ʻana i nā pale ʻē aʻe no nā kino o lalo o ke kaʻa e alakaʻi i ka ʻino wikiwiki. Pono nā pā Zinc-aluminum-magnesium, ʻoi aku ka nui no nā villa kahakai a me nā hale like.
(3) Ma nā wahi kūikawā e koi ana i ka pale ʻana i ka waikawa, e like me nā hale moa mahiʻai a me nā pā hānai, pono e hoʻohana ʻia nā pā zinc-aluminum-magnesium ma muli o ke ʻano corrosive o ka ʻōpala moa.
