ʻO ka galvanizing wela-dip ke kaʻina hana nui no ka pale ʻana i ka pala a me ka poponā pou kukui kila. ʻO ke kūlana a me ka mānoanoa o ka uhi zinc e hoʻoholo pololei i ke ola lawelawe o waho o ke pou kukui. He nui nā ʻoihana kūʻai ʻenekinia a me nā ʻoihana kūkulu kukui i maopopo ʻole e pili ana i nā kūlana aupuni, nā hoʻokaʻawale mānoanoa, a me nā koi hoʻololi hiʻohiʻona. I kēia lā, e wehewehe kikoʻī ana ka hale hana pou kukui galvanized waho ʻo Tianxiang i nā kūlana hoʻokō no nā pou kukui alanui HDG, nā palena mānoanoa o ka uhi zinc no nā mānoanoa pā like ʻole, a me nā kikoʻī koho no nā hiʻohiʻona kahakai a me uka, e kōkua iā ʻoe e pale i nā pilikia o nā uhi lahilahi a me nā mea maʻamau ʻole.
I. Nā Kūlana Hoʻokō Laulā no nā Pou Kukui Alanui HDG
Ma ke ʻano he mea nui no ke kukui kūlanakauhale a me ka ʻenekinia alanui, he mea koʻikoʻi ka uhi zinc o nā pou kukui alanui HDG i ka hoʻoholo ʻana i ka pale ʻana i ka popo a me ka pala a me ke ola lawelawe. Ma ke ʻano laulā, hahai nā papahana kūloko i ke kūlana aupuni GB/T 13912-2022 "Metallic Coatings - Technical Requirements and Test Methods for Hot-dip Galvanized Coatings of Steel Components". I kēia manawa, e pili ana nā papahana hoʻokuʻu aku kalepa kūlanakauhale a me nā ʻāina ʻē i nā kūlana galvanizing ISO honua pili.
Ua maopopo ka manaʻo o ke kūlana e pono i ke kia kukui kila holoʻokoʻa ke hoʻohana i ke kaʻina hana galvanizing wela no ke kino holoʻokoʻa, e pāpā ana i ka pīpī ʻana i ka ʻili wale nō a i ʻole ka mālama ʻana i ka galvanizing hapa. Ma hope o ka pickling, ka wehe ʻana i ka popo, a me ka fluxing, e hoʻokomo ʻia ke kila kila i loko o ka ʻauʻau zinc wela kiʻekiʻe e hana i kahi papa zinc i hoʻopaʻa ʻia me ka metallurgically. He paʻa ka hoʻopili ʻana o kēia papa a ʻaʻole hiki ke wehe maʻalahi ʻia, e kūpono ai no nā wahi waho paʻakikī e like me nā kahua ākea, nā wahi kahakai, a me nā wahi pulu, saline-alkali. ʻO ia ka hōʻoia kumu no ka pale ʻana i ka pala o nā kia kukui alanui.
II. Nā Koina Hoʻokaʻawale Mānoanoa no ka Papa Galvanized Hot-Dip
1. Nā Kūlana Mānoanoa e pili ana i ka Mānoanoa o ka Paia Pou
- Mānoanoa o ka paia < 4mm: ʻAʻole emi ka mānoanoa o ka papa zinc ma mua o 55μm, me ka mānoanoa kūloko liʻiliʻi loa ʻaʻole emi ma mua o 45μm. Hoʻohana nui ʻia no nā pou pā hale liʻiliʻi a me nā pou kukui alanui maʻalahi he 3-5 mika.
- Mānoanoa o ka paia 4mm～6mm: ʻAʻole emi ka mānoanoa o ka papa zinc ma mua o 70μm, me ka mānoanoa kūloko liʻiliʻi he 55μm. No nā pou kukui alanui maʻamau he 6-10 mika.
- Mānoanoa o ka paia > 6mm: ʻAʻole emi ka ʻili zinc maʻamau ma mua o 85μm me ka palena iki o 70μm. Pili i ke kukui kia kiʻekiʻe ma luna o 12 mika, ke alanui nui o ke kūlanakauhale, nā pou kukui alaloa.
2. Ke hoʻonui nei i ke koi ma nā ʻano noi like ʻole
Nā alanui kūlanakauhale a me nā alanui kuaʻāina maʻamau: Ua lawa ka mānoanoa o ke kūlana aupuni, a he 15-20 mau makahiki ke ola lawelawe.
Nā wahi pīpī paʻakai kahakai, nā pāka ʻoihana kemika, nā wahi haʻahaʻa a pulu: pono e hoʻomānoanoa ʻia ka uhi galvanized wela i ʻoi aku ma mua o 100μm i ka mānoanoa holoʻokoʻa e hoʻoikaika i kona kūpaʻa ʻana i ka pīpī paʻakai a me ka pala waikawa/alkali a hoʻolohi i ka oxidation a me ka popo o ka uhi zinc.
III. ʻAe ʻia ka maikaʻi o ka uhi ʻana o ka zinc—Nā koi liʻiliʻi loa
1. Ka maikaʻi o ke ʻano
ʻIli like a laumania, ʻaʻohe galvanizing piha ʻole, nā pehu, ka ʻili ʻana, nā nodules a me nā kiko ʻeleʻele. Pono e kaʻawale nā weld, nā awa a me nā flanges mai nā kihi make a me ka galvanizing piha ʻole.
2. Kūlana Hoʻopili
ʻAʻole e māwae a ʻili paha ka uhi zinc i ka wā o ka hahau ʻana me ka hāmare a me ka hoʻāʻo ʻoki ʻana, a e hoʻopaʻa pono ʻia i ke kila.
3. Ke ʻAno Hoʻāʻo
Nānā ʻana i nā laʻana he nui me ka hoʻohana ʻana i kahi ana mānoanoa o ka uhi zinc. Pono nā ʻāpana o luna, waena, a me lalo o ke pou a me ke kumu flange e kūlike i ke kūlana. Inā hāʻule kekahi laʻana, pono e nānā hou ʻia ka pūʻulu holoʻokoʻa a hana hou ʻia.
ʻO ka mānoanoa o ka papa galvanized wela e hoʻoholo pololei i ke ola lawelawe waho o nā pou kukui kila. Pono ke kūʻai ʻenekinia a me ka hoʻopilikino ʻana o ka mea hana e kūlike me ka mānoanoa galvanized e like me ka mānoanoa o ka paia maʻamau aupuni.Hale hana pou kukui galvanized wahoUa hōʻole ʻo Tianxiang i ka galvanization lahilahi maʻamau ʻole e hōʻoia i ka hoʻohana paʻa ʻana o nā papahana kukui i ka wā lōʻihi.
