No ka mea he ʻelua kaʻina hana no nā pā ʻauamo galvanized, he aha nā ʻokoʻa o kā lākou hana a me ka hoʻohana ʻana? E nānā pono kākou: -hoʻohu wela: I ka wā o ke kaʻina hana, hoʻomaʻamaʻa mua ʻia ka substrate e like me ka degreasing, pickling, holoi a me ka hoʻoheheʻe ʻana no ka wehe ʻana i ka ʻaila, ka ʻōpala, a me ka unahi. A laila, hoʻokomo ʻia i loko o ka zinc hoʻoheheʻe ʻia ma 445 degere -465 degere , e hana ana i kahi ʻāpana zinc- hao ma ka ʻili. He paʻa ikaika kēia papa a ʻaʻole hiki ke wehe i ka wā e hoʻohana ai. Ma hope o ka -hoohana lō'ihi, hō'ike ka papa zinc i ka pale anode kaumaha, e hana ana i -hopena pale ho'ōla. ʻO ke ola lawelawe o nā ʻauamo galvanized hiki ke piʻi i 15 mau makahiki, e hāʻawi ana i ka maikaʻi maikaʻi loa.
Electro-galvanizing: Ma o ka electrolysis, waiho ʻia nā ion zinc ma ka ʻili o ka substrate, e hana ana i kahi papa pale zinc maʻemaʻe like ʻole. ʻOi aku ka lahilahi o ka mānoanoa papa zinc ma mua o ka -dip galvanizing wela, ma kahi o 10μm-30μm. Ma ka ʻike maka, paheʻe ka ʻili a me ka waihoʻoluʻu, me ka liʻiliʻi o ka hopena i ka pololei o ke ana. Inā ʻaʻole kūpono ke kūpaʻa corrosion i nā koi maoli, hiki ke hana ʻia ka lapaʻau passivation ma luna o ka ʻili o nā papa ʻauamo galvanized e hoʻomaikaʻi hou aku i ke kūpaʻa corrosion. He kūpono ia no nā noi e koi ana i ka pololei kiʻekiʻe a me ka hoʻopau ʻana i ka ʻili, me ka haʻahaʻa haʻahaʻa o nā kumukūʻai hoʻopukapuka mua.
ʻOkoʻa ka -wea wela a me ka electro{1}}ʻokoʻa nā papa ʻauamo galvanized ʻaʻole i kā lākou hana hana wale nō akā i ko lākou ʻano hana a me nā wahi hoʻohana. Ma lalo nei, e hoʻohālikelike mākou iā lākou i nā kikoʻī:
| ʻano ʻano | Nā papa ʻauamo wela -luu | Electro-paʻa auamo |
| Mānoanoa papa zinc | 85μm-120μm, me kahi papa pale mānoanoa; | 10μm-30μm, he lahilahi ka papa pale; |
| ʻO ke kūpaʻa ʻino | ʻOi aku ka ikaika a kū i nā hoʻāʻo ʻana i ka paʻakai no ka ʻoi aku a i ʻole like me 500 mau hola, a me ke ola pale ʻana o waho o 10-15 mau makahiki; ʻO ka papa zinc he "anode kaumaha", a hiki ke pale i ka substrate me nā ʻōpala kūloko; | ʻOi aku ka nui a i ʻole like me 200 mau hola o ka hoʻāʻo ʻana i ka paʻakai ma hope o ka passivation, a me ka ʻeleʻele waho -ola o 3-5 mau makahiki; |
| Ka hoʻopili ʻana i ka zinc coating | Loaʻa iā ia ka ikaika ʻoi aku ma mua o a i like paha me 10 N/mm², ka hoʻopili ikaika ʻana, a me ka hoʻopaʻa ʻana i ka metallurgical paʻa, e ʻae iā ia e kū i ka piko a me ka hopena me ka hāʻule ʻole. | Ma lalo o nā kūlana maʻamau, loaʻa iā ia ka ikaika o ʻoi aku ma mua o a i ʻole like me 5N/mm², adhesion haʻahaʻa, a maʻalahi ke ʻili i ka wā e hoʻokau ʻia i ka ikaika o waho. |
| Ka nana aku | ʻAhinahina ka ʻili -hina, ʻaʻahu like ʻole, a kūlike me ka maʻamau GB/T 13912-2022, akā he haʻahaʻa haʻahaʻa kona. | He palahalaha a lauwili ka ʻili, me ka ʻike ʻole ʻia o nā hemahema, a he kiʻekiʻe o ka nani. |
| Ka pololei ana | E hoʻopili iki ke kaʻina hana galvanizing i ka pololei, e koi ana i ka hoʻoponopono hou ʻana. ʻO ka hapa galvanized dimensional e emi iho a like paha me ± 0.1mm. | He ʻuʻuku loa ka hopena i ka pololei ʻana, a ʻaʻohe deformation i ka wā o ke kaʻina galvanizing holoʻokoʻa, me ka hewa o ka liʻiliʻi a i ʻole like me ±0.05mm, kūpono ia no nā koi kiʻekiʻe-; |
| Ka hoʻohālikelike o ka substrate | Hiki ke koho ʻia ke kila kalapona mānoanoa -mānoanoa, ʻoi aku ke kila Q235B a me 45#; | He kūpono ia me nā ʻāpana kila ʻeleʻele -pā, haʻahaʻa{1}}a hiki ke hoʻohana ʻia no nā ʻāpana liʻiliʻi kiʻekiʻe; |
| Laulā nui | Hiki ke hoʻopilikino ʻia nā nui nui, me nā lōʻihi mai 50mm a 3000mm, ākea mai 30mm a 1200mm, a me nā mānoanoa mai 5mm a 80mm. | ʻO ka liʻiliʻi a me ka liʻiliʻi - nui, me ka lōʻihi mai 20mm a 1500mm, nā laula mai 15mm a 800mm, a me ka mānoanoa mai 3mm a 50mm; |
| Nā waiwai mīkini | Hiki ke hoʻololi iki i nā mahana kiʻekiʻe i ka paʻakikī o ka substrate, akā hiki ke hoʻihoʻi hou ʻia ma o nā kaʻina hana hoʻomaha lohi a me ka hoʻoponopono ʻana, a e kūlike ka ikaika compressive/shear me ka substrate kumu. | ʻAʻole pili ke kaʻina hana o ka lumi i nā waiwai mechanical o ka substrate, a mālama pono ʻia ka ikaika compressive, shear ikaika a me ka paʻakikī, kūpono ia no nā noi kikoʻī me nā koi hana mechanical stringent. |

No ke aha ʻoe e kūʻai ai i nā papa ʻauamo galvanized mai kā mākou hui? No ka mea, loaʻa i kā mākou hui nā mea maikaʻi i ka hana ʻana:
Hiki ke hana
Loaʻa i kā mākou hui kahi hui R&D ʻoihana e hiki ke pane koke i nā pono pilikino o nā mea hoʻohana. Hoʻohui pū ʻia me nā lako hana a me ka hoʻāʻo ʻana, hiki iā mākou ke hoʻokō i ka -makemake nui o nā mea hoʻohana ma ka honua holoʻokoʻa a hōʻoia i ka lawe wikiwiki ʻana.
Kumukuai
ʻO ka loaʻa ʻana o ka waiwai maka nui -nui e hoʻomalu i nā kumukūʻai hana, a ʻoiai e hōʻoia ana i ka maikaʻi o ka huahana, hāʻawi ia i nā mea hoʻohana i nā kumukūʻai hoʻokūkū, ʻoi aku hoʻi no nā mea hoʻohana hui like - lōʻihi, hiki ke kōkua iā lākou e hōʻemi i nā kumukūʻai kūʻai.
ʻIke kālepa haole
Ua hoʻokumu kā mākou hui i nā pilina hana lōʻihi-me nā ʻāina he nui, me ʻAmelika Hui Pū ʻIa, Rusia, a me United Kingdom. Ua kamaʻāina mākou i nā kulekele hoʻokomo a me nā koi mākeke o kēia mau ʻāina a hāʻawi i nā mea hoʻohana i nā hoʻonā i hoʻohui ʻia e pili ana i ka hana maʻamau, logistic, a ma hope o -lawelawe kūʻai.
Loaʻa i nā papa ʻauamo Galvanized kahi ākea ākea o nā noi, no laila hopohopo nui nā mea hoʻohana i ka maikaʻi o ka huahana. Pehea la kakou e noonoo ai i kona maikai? Hiki iā mākou ke loiloi iā ia mai nā ʻano he nui, e like me ke ʻano, ka uhi zinc, ka pololei, a me ka hana.
Ka nana aku
Pono ka ʻili a maʻemaʻe, me ka ʻole o nā hemahema e like me nā wahi i hoʻopaʻa ʻole ʻia, ke kumu i ʻike ʻia, nā kiko ʻeleʻele, nā lua, a i ʻole nā pua. E nānā i ka ʻili no nā ʻōpala, ʻāhuʻi, a i ʻole ka hoʻololi ʻana, a e hōʻoia i ka palahalaha ʻole o nā wiliwili -ʻole, a ʻaʻole e hemo ka ʻili zinc.
01
Papa Zinc
E nānā inā kū ka mānoanoa me ka maʻamau a inā he mau mānoanoa like ʻole kūloko. Hiki iā ʻoe ke ʻohi māmā i ka ʻili me kahi mea paʻakikī. Inā ʻaʻohe ʻili a ʻili paha, e makaʻala i ka uhi piha ʻana o nā kihi a inā paha ua ʻāhuʻi ka papa zinc a me nā puʻupuʻu.
02
pololei
E hoʻohana i ka lipine ana e ana i ka lōʻihi o ka ʻaoʻao a me ka mānoanoa o ka paia e hōʻoia i ko lākou kūpono i nā kūlana aupuni. E kau i ka papa ma kahi pālahalaha a nānā inā pololei ia, me ka ʻike ʻole ʻia o ka piʻo ʻana, ka wili a i ʻole ke hili ʻana.
03
hoʻokō
ʻO ka hana nui o nā papa ʻauamo galvanized ko lākou pale ʻana i ka corrosion. No laila, hiki iā mākou ke hoʻāʻo iā lākou me ka 5% sodium chloride solution me ka pH o 6.5-7.2 a me kahi mahana o 35 degere e loiloi i ka papa zinc.
04
Nā huahana pale: ʻO ka pā ʻauamo galvanized, China galvanized plate plate, nā mea hoʻolako, hale hana
