He aha nā ʻokoʻa ma waena o nā wili kila a me galvalume a me nā lau

ʻO ka uhi ʻili o nā coils zinc aluminized he 55% aluminika, 43.5% zinc a me kahi mea liʻiliʻi o nā mea ʻē aʻe.ʻO ka ʻili o ka ʻili zinc aluminized he hale honeycomb ma lalo o ka microscopic view, a ʻo ka "honeycomb" i hana ʻia me ka alumini ka zinc.I kēia hihia, ʻoiai ke pāʻani nei ka pale alumini-zinc i ka pale o ka anode, ma kekahi ʻaoʻao, ma muli o ka emi ʻana o ka zinc content, ma ka ʻaoʻao ʻē aʻe, ua kāwili ʻia ka mea zinc i ka alumini a ʻaʻole maʻalahi ke electrolyze. no laila ua emi loa ka hana o ka pale anode.No laila, i ka wā e uhi ʻia ai ka alumini Ua ʻoki ʻia ka pā zinc, a e ʻula koke ia ke nalowale a pale ʻia ka ʻaoʻao i ʻoki ʻia.No laila, pono e ʻoki ʻia ka pā alumini-zinc e like me ka hiki.Ke ʻoki ʻia, hiki ke pale ʻia ka lihi ma ka hoʻohana ʻana i ka pena anti-rust a i ʻole ka pena waiwai zinc.ʻOi aku ka lōʻihi o ke ola o nā papa.

ʻO ka ʻili o nā wili kila galvalume/aluzinc/zincalum e hāʻawi i kahi pua hoku maʻemaʻe, pālahalaha a nani, a ʻo ke kala kumu he keʻokeʻo kālā.ʻO ka hoʻolālā hoʻopili kūikawā e loaʻa iā ia ke kūpaʻa corrosion maikaʻi loa.ʻO ke ola lawelawe maʻamau o ka pā alumini-zinc hiki ke hiki i ka 25a, a maikaʻi ke kūpaʻa wela a hiki ke hoʻohana ʻia i kahi kiʻekiʻe wela o 315 ° C;maikaʻi ka hoʻopili ʻana o ka uhi a me ka kiʻi pena, a he mau mea hana maikaʻi kona, a hiki ke kuʻi, ʻoki, welded, etc.;He maikaʻi loa ka conductivity o ka ʻili.

Hoʻokumu ʻia ka haku mele ʻana me 55% aluminika, 43.4% zinc, a me 1.6% silika i ka ratio paona.ʻO ke kaʻina hana o ka wili kila galvalume ua like ia me nā wili kila galvanized a me ka aluminized coilst, kahi hana hoʻoheheʻe mau.ʻO ka galvalume/aluzinc coil me 55% aluminum-zinc alloy coating i ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion ma mua o ka pale kila galvanized o ka mānoanoa like i ka wā e ʻike ʻia ai i kahi kaiapuni like ma nā ʻaoʻao ʻelua.ʻO ka 55% aluminum-zinc alloy coated aluminum-zinc steel plate ʻaʻole wale ka maikaʻi o ka corrosion resistance, akā loaʻa nō hoʻi ka adhesion a me ka maʻalahi o nā huahana kala.

ʻO ka ʻokoʻa ma waena o galvalume/aluzinc a me galvanized coils ʻo ia ka ʻokoʻa o ka uhi.Hoʻokaʻawale ʻia ka ʻili o ka pepa galvanized me kahi papa o ka zinc material, e hana ana he pale anodic no ka mea kumu, ʻo ia hoʻi, ka pale corrosion ʻē aʻe o ka mea zinc.Ma waho aʻe o ka hoʻohana ʻana i ka mea kumu, hiki ke hōʻino wale ʻia ka mea kumu i loko i ka wā i hoʻopau ʻia ai ka zinc.
