Pono anei e hoʻopili ʻia nā pou alanui solar i ke anu a i ʻole ke wela?

I kēia mau lā, ʻo nā wili kila Q235 premium ka mea kaulana loa nonā pou alanui solarMa muli o ka pilikia o nā kukui alanui solar i ka makani, ka lā, a me ka ua, pili ko lākou lōʻihi i ko lākou hiki ke kū i ka pala. Hoʻopili pinepine ʻia ke kila i galvanized e hoʻomaikaʻi i kēia.

ʻElua ʻano o ka uhi ʻana i ka zinc: ka hoʻoluʻu wela a me ka hoʻoluʻu anu. No ka mea,nā pou kila galvanized welaʻoi aku ka paʻa o nā pou i ka pala, ke aʻo pinepine nei mākou e kūʻai iā lākou. He aha nā ʻokoʻa ma waena o ka hot-dip a me ke cold-dip galvanizing, a no ke aha i ʻoi aku ai ka paʻa o nā pou galvanized hot-dip? E nānā kākou me Tianxiang, kahi hale hana pou alanui Kina kaulana.

1) Galvanizing Anu (Kāhea ʻia hoʻi he electro-galvanizing): Ma hope o ka hoʻohemo ʻana i ka momona a me ka pickling, hoʻokomo ʻia ke kila i loko o kahi hopena paʻakai zinc. Hoʻopili ʻia ka hopena i ka electrode maikaʻi ʻole o nā lako electrolysis, a kau ʻia kahi papa zinc ma ke alo, i hoʻopili ʻia i ka electrode maikaʻi. Ke hoʻā ʻia ka mana, i ka neʻe ʻana o ke au mai ka electrode maikaʻi a i ka electrode maikaʻi ʻole, hana ʻia kahi papa waiho zinc like, mānoanoa, a paʻa pono ma luna o ka ʻili o ka paipu kila.

2) Ke galvanizing wela: Hoʻokomo ʻia ka ʻili kila i loko o ka zinc heheʻe ma hope o ka hoʻomaʻemaʻe ʻana a me ka hoʻāla ʻana. Hoʻomohala ʻia kahi papa o ka zinc metala ma luna o ka ʻili kila ma muli o kahi hopena physicochemical ma waena o ka hao a me ka zinc ma ka interface. Ke hoʻohālikelike ʻia me ke galvanizing anuanu, hana kēia ʻano hana i kahi pilina ikaika ma waena o ka uhi a me ka substrate, e hoʻomaikaʻi ana i ka mānoanoa o ka uhi ʻana, ka lōʻihi, ka hana mālama ʻole, a me ke kumukūʻai kūpono.

1) Ke ʻAno Hana: Hoʻomaopopo ko lākou mau inoa i ka ʻokoʻa. Hoʻohana ʻia ka zinc i loaʻa ma ka mahana o ka lumi i nā paipu kila galvanized anu-anu, ʻoiai ʻo ka zinc i loaʻa ma 450°C a i 480°C i hoʻohana ʻia i ka galvanizing wela-anu.

2) Mānoanoa o ka Uhi ʻana: ʻOiai ʻo ka galvanizing anu-dip ka mea maʻamau e hana i ka mānoanoa o ka uhi ʻana he 3-5 μm wale nō, kahi e maʻalahi ai ka hana ʻana, he haʻahaʻa kona kūpaʻa i ka pala. I ka hoʻohālikelike ʻana, hāʻawi pinepine ka galvanizing wela-dip i ka mānoanoa o ka uhi ʻana he 10μm a ʻoi aku paha, ʻoi aku ka nui o kona kūpaʻa i ka pala ma mua o nā pou kukui galvanized anu-dip.

3) ʻAno Uhi: Ua hoʻokaʻawale ʻia ka uhi a me ke substrate e kahi papa hui palupalu i ka galvanizing wela. Eia nō naʻe, no ka mea, ua hana ʻia ka uhi me ka zinc, kahi e hopena ai i kahi uhi like me nā pores liʻiliʻi, e emi ai ka maʻalahi o ka pala, ʻaʻohe hopena iki o kēia i kona kūpaʻa ʻana i ka pala. I ka hoʻohālikelike ʻana, hoʻohana ka galvanizing anu i kahi uhi i hana ʻia me nā ʻātoma zinc a me kahi kaʻina hana hoʻopili kino me nā pores he nui, kahi e maʻalahi ai i ka pala o ke kaiapuni.

4) ʻOkoʻa Kumukūʻai: ʻOi aku ka paʻakikī a me ka paʻakikī o ka hana ʻana o ka galvanizing wela. No laila, hoʻohana pinepine nā ʻoihana liʻiliʻi me nā lako kahiko i ka galvanizing anu, e hopena ana i nā kumukūʻai haʻahaʻa loa. ʻOi aku ka maikaʻi o ka kaohi ʻana o nā mea hana galvanizing wela nui a paʻa, e alakaʻi ana i nā kumukūʻai kiʻekiʻe.

E ʻōlelo paha kekahi poʻe ʻoiai inā ʻike lākou i ka ʻokoʻa ma waena o ke galvanizing anu-dip a me ke galvanizing wela-dip, ʻaʻole hiki iā lākou ke ʻike i ka ʻokoʻa. He mau ʻano hana kēia i ʻike ʻole ʻia e ka maka ʻōlohelohe. He aha inā hoʻohana kahi mea kūʻai aku kolohe i ke galvanizing anu-dip ma kahi o ke galvanizing wela-dip? ʻOiaʻiʻo, ʻaʻohe pono e hopohopo. ʻO ke galvanizing anu-dip a meka hoʻoheheʻe ʻana i ka welahe maʻalahi loa ke hoʻokaʻawale.

He laumania nā ʻili galvanized anu-dip, ʻōmaʻomaʻo melemele ka hapa nui, akā he ʻālohilohi paha kekahi, he keʻokeʻo uliuli, a he keʻokeʻo paha me ka ʻōlinolino ʻōmaʻomaʻo. Hiki ke ʻano palalulu a lepo paha. ʻOi aku ka ʻino o nā ʻili galvanized wela-dip, i ka hoʻohālikelike ʻana, a he pua zinc paha, akā ʻālohilohi loa ko lākou ʻano a he keʻokeʻo kālā. E hoʻolohe i kēia mau ʻokoʻa.
