Wehewehe ʻana o ka hoʻopalapala
(1) Hoʻopili spangle maʻamau
Ma ke kaʻina hana paʻa paʻa maʻamau o ka papa zinc, ulu manuahi nā hua zinc e hana i kahi uhi me ka morphology spangle maopopo.
(2) hoʻemi ʻia ka uhi ʻana o ka spangle
I ka wā o ka hoʻopaʻa ʻana o ka papa zinc, ua kaupalena ʻia nā kīʻaha 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, ʻaʻole ʻike ʻia ka spangle morphology, 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 a puni ka uhi. He ʻeleʻele ʻeleʻele kēia uhi me ka ʻole o ka ʻulaʻula metala, a ua maʻalahi 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 hou ʻana.
(5) ka uhi ʻokoʻa
No nā ʻaoʻao ʻelua o ka pepa kila i hoʻopaʻa ʻia, koi ʻia nā uhi me nā paona zinc like ʻole.
(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 hoʻopau ʻia.

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, nā inclusions, ka pōʻino mechanical, ka hana maikaʻi ʻole o ke kumu kila, nā ʻaoʻao wavy, buckling, incompatibility nui, Embossing, inconsistent zinc layer mānoanoa, roll printing, etc.
ʻO nā kumu nui no ka hāʻule ʻana o ka papa zinc: ka hoʻoheheʻe ʻana o ka ʻili, nā pūhui silika, ka emulsion i ʻōwili ʻia i ke anuanu, kiʻekiʻe loa ka lewa oxidizing a me ka wahi hau pale hau i ka ʻāpana NOF, kūpono ʻole ka ea-wahie ratio, haʻahaʻa hydrogen kahe, hoʻoheheʻe oxygen i loko o ka umu, hao hao ʻO ka mahana o ke komo ʻana i ka ipu hao he haʻahaʻa, haʻahaʻa ka ʻaoʻao o ka umu ahi, haʻahaʻa ka ʻaoʻao o ka umu ahi ma ka puka, a me ka pauku o ka umu. He haʻahaʻa ka wela o ka umu ahi ma ka ʻāpana NOF, ʻaʻole e hoʻoheheʻe ʻia ka momona, haʻahaʻa ka ʻike alumini o ka ipu hao, wikiwiki ka wikiwiki o ka hui, ʻaʻole lawa ka emi ʻana, a paʻa ka wai zinc Ua pōkole loa ka manawa a ʻoi aku ka mānoanoa o ka uhi.
ʻO nā kumu o ka ʻeleʻele keʻokeʻo a me nā kiko ʻeleʻele penei: ua hoʻokumu ʻia nā kiko ʻeleʻele e ka oxidation hou o ka ʻeleʻele keʻokeʻo.
ʻO nā kumu nui o ka rust keʻokeʻo:
(1) Poor passivation, lawa ole a uneven passivation film mānoanoa;
(2) ʻAʻole i ʻaila ʻia ka ʻili a i ʻole ke koena o ka wai ma luna o ka ʻili 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 me a mālama pū ʻia me nā mea hoʻoheheʻe ʻē aʻe e like me ka waikawa a me ka alkali.

ʻO ka hui he ʻelua laina hana nui ākea ākea a mānoanoa me ka ʻenehana hilinaʻi, a loaʻa iā ia ka mana piha e hana i ʻoi aku ma mua o 5 miliona mau toni o ke kila hoʻoheheʻe ʻia a ʻoi aku hoʻi ma mua o 3 miliona mau pā kila i kēlā me kēia makahiki. ʻOi aku ka nui o nā limahana ma mua o 10,000. Loaʻa iā ia ka ʻenehana hoʻomaʻamaʻa ʻana i ka wela o ka pā hao, ka ʻenehana hana ʻenehana paʻa kila ʻoi aku ka mānoanoa, electroslag remelting steel production technology, etc.
Hoʻopili a hoʻouna
Hiki iā mākou ke hāʻawi: ka pahu pallet lāʻau, ka pahu pahu lāʻau, ka hoʻopaʻa ʻana i ke kila, ka palaki palaki a me nā ʻano hana ʻē aʻe. Makemake mākou e hoʻopili a hoʻouna i nā huahana e like me ke kaumaha, nā kikoʻī, nā mea waiwai, nā kumukūʻai waiwai a me nā koi o ka mea kūʻai aku.
Kaʻa kaʻa: Hiki iā mākou ke hāʻawi i ka pahu a i ʻole ka lawe nui ʻana, ke alanui, ke alahao a i ʻole ke ala wai uka a me nā ʻano kaʻa ʻāina ʻē aʻe no ka lawe ʻana aku. ʻOiaʻiʻo, inā loaʻa nā koi kūikawā, hiki iā mākou ke hoʻohana i ka halihali ea.
