Wehewehe ʻana o ka pā
(1) Hoʻopili spangle maʻamau
I ke kaʻina hana paʻa paʻa maʻamau o ka papa zinc, ulu manuahi nā hua zinc e hana i kahi uhi me ka ʻike ʻia o ka spangle morphology.
(2) hōʻemi ʻia ka uhi ʻana o ka spangle
I ka wā o ka hoʻopaʻa ʻana o ka papa zinc, ua kaupalena ʻia nā ʻano hua aniani zinc e hana i ka uhi spangle liʻiliʻi loa.
(3) Spangle-free coating spangle-free
Loaʻa iā ia ma ka hoʻoponopono ʻana i ka haku mele ʻana o ka hoʻonā plating, ʻaʻohe ʻike ʻia o ka morphology spangle, a loaʻa iā ia kahi uhi ʻili like.
(4) Zinc-iron alloy coating
ʻO ke kaula kila ma hope o ka hele ʻana i loko o ka ʻauʻau galvanizing ua mālama ʻia i ka wela e hana i kahi ʻāpana o ka zinc a me ka hao i loko o ka uhi.He ʻeleʻele ʻeleʻele ke ʻano o kēia uhi me ka ʻole o ka luster metala, a maʻalahi hoʻi i ka pauka i ka wā o ke kaʻina hana ʻino.Ma waho aʻe o ka hoʻomaʻemaʻe ʻana, hiki ke pena pololei ʻia ka uhi me ka ʻole o ka mālama ʻana.
(5) ka uhi ʻokoʻa
No nā ʻaoʻao ʻelua o ka pepa kila galvanized, pono nā uhi me nā paona ʻokoʻa zinc.
(6) Kaʻili pahee
ʻO ka hoʻomaʻamaʻa ʻana he ʻano ʻolokaʻa anuanu o ka pā kila galvanized me ka liʻiliʻi o ka deformation no hoʻokahi a i ʻole kekahi o kēia mau kumu.
E hoʻomaikaʻi i ke ʻano o ka ili o ke kila galvanized a i ʻole kūpono no ka uhi ʻana;e hoʻemi iki i ka laina paheʻe (Lüdes line) a i ʻole nā wrinkles i hana ʻia ke hana ʻia ka huahana i pau.

ʻO ka mea nui: ka hoʻoheheʻe ʻana, nā ʻōpala, nā wahi passivation, nā ʻāpana zinc, nā ʻaoʻao mānoanoa, nā ʻili pahi ea, nā ʻili pahi ea, ke kila i hōʻike ʻia, inclusions, mechanical damage, poor performance of the steel base, wavy edges, buckling, size incompatibility, Embossing, inconsistent ka mānoanoa papa zinc, ka paʻi ʻōwili, etc.
ʻO nā kumu nui o ka hāʻule ʻana o ka papa zinc: ka hoʻoheheʻe ʻana o ka ʻili, nā pūhui silikoni, ka emulsion i ʻōwili ʻia i ke anuanu, kiʻekiʻe kiʻekiʻe o ka ea a me ka wahi hau pale kinoea i ka ʻāpana NOF, ʻaʻole kūpono ka ea-wahie ratio, haʻahaʻa hydrogen kahe, oxygen infiltration. i loko o ka umu ahi, wehe i ke kila ʻO ka mahana o ke komo ʻana i ka ipu hao he haʻahaʻa, haʻahaʻa ke kaomi o ka umu ma ka ʻāpana RWP, a ʻo ka hoʻoheheʻe ʻana o ka puka umu, haʻahaʻa ka wela o ka umu ma ka ʻāpana NOF, ʻaʻole e hoʻoheheʻe ka momona, ka ʻike alumini. ʻO ka ipu hao zinc he haʻahaʻa, ʻoi aku ka wikiwiki o ka ʻāpana, ʻaʻole lawa ka hoʻemi ʻana, a noho ka wai zinc Ua pōkole loa ka manawa a ua mānoanoa loa ka uhi.
ʻO nā kumu o ke keʻokeʻo keʻokeʻo a me nā kikoʻeleʻele penei: ua hana ʻia nā kiko ʻeleʻele e ka hoʻonā hou ʻana o ka ʻeleʻele keʻokeʻo.
ʻO nā kumu nui o ka rust keʻokeʻo:
(1) Poor passivation, lawa ole a uneven passivation film mānoanoa;
(2) ʻAʻole ʻaila ʻia ka ʻili a i ʻole ke koena o ka wai ma luna o ka ʻili;
(3) Aia ma ka ili o ke kila kaula ka makū i ka wā e wili ai;
(4) ʻAʻole maloʻo loa ka passivation;
(5) Ka wai a i ʻole ka ua i ka wā o ka lawe ʻana a i ʻole mālama ʻia;
(6) Ua mālama ʻia ka huahana i hoʻopau ʻia no ka lōʻihi loa;
(7) Hoʻopili ʻia ka pepa galvanized a mālama ʻia me nā mea hoʻoheheʻe ʻē aʻe e like me ka waikawa a me ka alkali.
Waihona
ʻAe ʻia ka huahana i hoʻopau ʻia e mālama ʻia i loko o ka hale kūʻai no ka lōʻihi o ʻekolu mau mahina e pale aku i ka oxidation ma muli o ka mālama nui ʻana.
