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 kahi 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 anuanu, 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 ʻana 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 o ka zinc.ʻAʻole nui ka ʻokoʻa o 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 pale kila galvanized no nā papa kumu no nā ʻāpana prefabricated 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 kikoʻī 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 kūloko o loko, nā ʻāpana chassis, nā ʻāpana kino o ke kaʻa, nā papa cast-in-situ, 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 kila i ʻōwili ʻia ʻo DD51DZ.HD340LADZ HR340LA HR420IA HR5501A, etc.:
Hoʻohālikelike ʻia ka pepa galvanized ʻōwili anuanu 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.
