Ma ke kalepa kumu o na galvanized steel sheets, anu ka olokaa ana i basically dominated e wela galvanizing, a wela owili substrates loa loa. No laila, he aha ka ʻokoʻa ma waena o nā huahana galvanized ʻōwili wela a me ke anuanu? E wehewehe pōkole kākou i kēia mau wahi:

1. Kumukuai
Ma muli o ka nele o ke kaʻina hana i hoʻohālikelike ʻia me nā substrates i ʻōwili ʻia, ʻoi aku ka haʻahaʻa o ka galvanizing hot dip galvanizing o nā substrates i ʻōwili ʻia me ka haʻahaʻa ma mua o ka ʻōwili anu, ʻoi loa ma muli o ke kumukūʻai o ka quenching a me ka ʻōwili anu, ʻoiai nā kaʻina hana ʻē aʻe.
2. Nā hiʻohiʻona maikaʻi
Ma muli o ka ʻike ʻana o ka substrate wela wela i ka pickling acid, passivation, a me ke kinai ʻana e hoʻoneʻe i nā koena o ka ʻili, ʻaʻole maʻalahi kona ʻili, a ʻoi aku ka maikaʻi o ka adhesion o ka papa zinc. ʻOi aku ke kaumaha o ka mānoanoa o ka uhi ma mua o 140/140a/m2, akā ʻaʻole pololei ka kikoʻī o ka mānoanoa e like me ka ʻōwili anuanu, no ka mea, ʻo ka hapa nui o nā papa zinc he mānoanoa, a ʻaʻole like ka hoʻololi ʻana i ka mānoanoa zinc. ʻAʻole nui ka ʻokoʻa i ka hana kino, a ʻoi aku ka maikaʻi o kekahi mau hana hoʻomaikaʻi no nā kaʻa anu
3. Hoʻohana nui
No nā kaʻa wela, hoʻohana pinepine ʻia nā ʻāpana kila galvanized no nā papa kumu no nā ʻāpana i hana mua ʻia me nā koi haʻahaʻa haʻahaʻa akā ʻoi aku ka ikaika compressive kiʻekiʻe a me nā koi mānoanoa no ka mea ʻaʻole maikaʻi ka maikaʻi o ko lākou ʻano holoʻokoʻa a me ka maikaʻi o ka ʻili e like me nā papa kumu i ʻōwili ʻia. ʻoi aku ka mānoanoa o ka mānoanoa ma mua o nā ʻāpana kila galvanized i ʻōwili ʻia,
No ka laʻana, nā ʻāpana o nā mea pono hale e like me nā mīkini holoi piha piha a me nā pahu hau, nā ʻāpana o loko, nā ʻāpana chassis, nā ʻāpana kino o ke kaʻa, nā papa hoʻolei i loko o kahi, nā pale ala, nā ʻāpana kila huki anu, etc.
Ma muli o ke kumu kūʻai haʻahaʻa o nā pale kila galvanized wela, a hele pū me ka holomua ʻenehana, ke piʻi nei ka mānoanoa o nā kikoʻī a me nā hiʻohiʻona, a ke piʻi mālie nei ke koi.
4. Hoʻohālike
ʻO ke kumu hoʻohālike maʻamau o ka pā kila galvanized wela ʻo DD51DZ.HD340LADZ HR340LA HR420IA HR5501A, etc.:
Hoʻohālikelike ʻia ka pepa galvanized ʻōwili anu me DC51D Z.HC340LAD ZHC340LA, HC420LA, HC550LA, etc.:
Aia kekahi kumu hoʻohālike ʻaʻole kikoʻī i nā substrate i ʻōwili ʻia a wela paha, e like me DX51D Z, hiki ke noʻonoʻo ʻia ʻo ia ka pepa galvanized wela.
