ʻO ka hoʻohana ʻana i ka coil Galvalume a me nā pono

ʻO Galvalume coil /Aluzinc coil / Zincalum coil ʻo Zn-Al alloy i uhi ʻia, a ʻo ka hoʻohui ʻana he 55% Al, 43.3% Zn, a me 1.6% Si.Bseides ka waihoʻoluʻu kumu, he uliuli, ʻōmaʻomaʻo, gula a me ka ʻulaʻula ka aluzinc coil.No kona pale ʻana i ka corrosion maikaʻi loa, ke hoʻololi mālie nei kēia ʻano kila i ke kila galvanized a hoʻohana nui ʻia a puni ka honua.

He laumania ka ʻili a he maikaʻi ke kūʻē i ka corrosion o ka lewa.He 2-6 mau manawa ke kiʻekiʻe o kona pale ʻana i ka lewa ma mua o ka pepa galvanized wela me ka mānoanoa o ka uhi like.I ka manawa like, loaʻa iā ia ke kūpaʻa corrosion kiʻekiʻe e like me ka pepa alumini wela wela, alumini-zinc alloy coated steel sheet Hiki ke hoʻohana ʻia no ka manawa lōʻihi ma kahi kiʻekiʻe e like me 315 ℃, a me ka lōʻihi. - hoʻohana manawa ma kahi mahana o 500 ℃ ~ 600 ℃;ʻoi aku ka maikaʻi o ka pale ʻana i ka wai a me ka pale ʻana i ka lepo, a ʻoi aku ka maikaʻi o kona kūpaʻa ʻana i ka wai ma mua o ka pepa galvanized wela a me ka pepa alumini wela.ʻOi aku ka maikaʻi o ka ʻino ʻana o ka lepo ma mua o ka pepa galvanized wela;ʻOi aku ka maikaʻi o ka pena a me ka hana hoʻoponopono maikaʻi, a ʻo kona processability a me ka weldability e like me ka wela-dip galvanized sheet, hiki ke hana ʻia e ke kuʻi anu, stamping, etc., a he helehelena maikaʻi.
Aluminum-zinc alloy coated steel sheets loaʻa nā hiʻohiʻona ʻelua o ka pale kila wela wela a me ka pepa kila alumini wela.No laila, ma kahi e hoʻohana ʻia ai ka peʻa kila wela, hiki ke hoʻohana ʻia ka pale kila alumini-zinc alloy, a hiki ke hoʻololi ʻia i kahi ʻāpana alumini kila.Loaʻa iā ia ka laulā o nā noi, e like me nā panela o ka hale, nā pā pā, nā kilika kila māmā, nā radiators hoʻomehana, nā kino kaʻa, nā pahu wahie, nā kaula hao i hoʻopaʻa ʻia i ke kila, nā hale ʻōmaʻomaʻo plastik, nā hale ʻai, nā ipu hoʻouna, nā mea pono hale a me nā mea hana, nā umu, pahū. -ʻo nā kāʻei kila, nā uhi waho o ka ea a me nā ʻōnaehana ea, nā mea hoʻomehana wai o ka lā, nā pahu pahu no nā huahana kemika, a me nā substrates pā kala, nā paipu welded, nā puka aniani, nā mea kila i hana ʻia i ke anuanu i ka ʻoihana metallurgical, etc. ākea loa ka manaʻolana noi.
ʻOi aku ka kiʻekiʻe o ke kumu kūʻai o ka alumini-zinc alloy coated steel sheet ma mua o ke kila wela wela, akā no ka mea ʻoi aku ka liʻiliʻi o ka umekaumaha o ka alumini ma mua o ka zinc, ʻo ka gravity kikoʻī o ka alumini-zinc alloy coating he 3.75kg/dm3 wale nō. , oiai ka umekaumaha kikoo o ka zinc he 7.1kg/dm3, no laila ke kaumaha o ka uhi ana ʻO ka mānoanoa o ka alumini-zinc alloy coating o 150g/m2 (ʻaoʻao ʻelua) ua like ia me ka pā kila wela me ka. ʻO ke kaumaha o ka uhi ʻana he 275g/m2 (ʻaoʻao ʻelua), ka mea e hoʻopakele nui ai i ka metala uhi ʻoi aku ka pipiʻi.

ʻO ke kūpaʻa ʻino nui: ʻo ke kūpaʻa corrosion o ka huahana he 6-8 mau manawa ma mua o ka pepa galvanized maʻamau, a ʻaʻole ia e pala no 20 mau makahiki i nā ʻano like ʻole;
ʻO ke kūpaʻa ʻana o ka wela wela: ʻo ka hoʻohana mau ʻana a i ʻole ka hoʻohana ʻana i kahi kaiapuni kiʻekiʻe o 315 degere Celsius ʻaʻole ia e hoʻoneʻe i ka ʻili a i ʻole deformation;ʻO ka hoʻohana mau ʻana a i ʻole ka hoʻohana ʻana i kahi kaiapuni kiʻekiʻe o 490 degere Celsius ʻaʻole ia e hoʻoheheʻe nui ʻia a hana ʻole i ka unahi hao hao;
Hōʻikeʻike wela kiʻekiʻe: ʻOi aku ka kiʻekiʻe o ka wela o ka huahana ma mua o 75%, ʻo ia ka pālua o ka pepa galvanized;
ʻO ka hana maʻalahi: hiki iā ia ke hoʻokō i ka hana o ka stamping, shearing, bending, etc.;
ʻO ka hiʻohiʻona nani: ke kala kala keʻokeʻo snowflake, nani a nani, hiki ke hoʻohana pololei me ka pena ʻole;
ʻO ka hoʻoulu ʻana i ka ʻili: He substrate maikaʻi ia no ka uhi ʻana i ka pena.Hiki ke hāʻawi i ka pale ʻoi aku ka maikaʻi a pale i ka corrosion ma lalo o ka uhi organik.
