Paipu galvanized welahana ʻia me ka hoʻoheheʻe ʻana i ka metala i hoʻoheheʻe ʻia me ke pani hao e hana i kahi ʻāpana paʻa, a laila e hoʻopaʻa ʻia ke pani a me ka uhi. ʻO ka galvanizing wela ka holoi mua ʻana i ka waika i ka paipu kila no ka wehe ʻana i ka lepo. Ma hope o ka holoi ʻana i ka waika, hoʻomaʻemaʻe ʻia ka paipu i loko o kahi hopena o ka ammonium chloride a i ʻole zinc chloride, a i ʻole ka hui ʻana o nā mea ʻelua, ma mua o ka hoʻokomo ʻia ʻana i loko o ka pahu galvanizing wela.
Hāʻawi ka Hot-dip galvanizing i nā mea maikaʻi e like me ka uhi ʻana i ka lole, ka hoʻopili ikaika, a me ke ola lawelawe lōʻihi. Hoʻokomo ka substrate paipu kila i nā hopena kino a me ke kemika paʻakikī me ka hoʻoheheʻe galvanizing hoʻoheheʻe ʻia, e hana ana i kahi papa hoʻoheheʻe zinc-hao. Hoʻohui ʻia kēia ʻāpana paʻa me ka papa zinc maʻemaʻe a me ka substrate paipu kila, e hopena i ka pale ʻana i ka corrosion ikaika.
1. Ke kūlike o ka uhi zinc: ʻAʻole pono e ʻulaʻula nā mea hoʻohālike paipu kila (ʻeleʻele keleawe) ma hope o ka hoʻomau mau ʻia ʻana i loko o ka solution keleawe sulfate ʻelima manawa.
2. Ka maikaʻi o ka ʻili: Ka ʻili opaipu kila galvanizedpono e loaʻa i ka uhi zinc piha, ʻaʻohe wahi ʻeleʻele i uhi ʻole ʻia. ʻAe ʻia nā nodules liʻiliʻi a me ka zinc localized.
3. Ke kaumaha papa Galvanized: E like me nā koi o ka mea kūʻai aku, hiki i ka paipu kila galvanized ke hoʻāʻo i ke kaumaha o ka zinc layer, me ka waiwai awelika ʻaʻole i emi iho ma mua o 500 g/m², ʻaʻole pono e emi iho ma mua o 480 g/m².
Hoʻokomo ʻia ka paipu galvanized wela i hana ʻia e nā paipu ʻeleʻele i loko o ka wai zinc no ka galvanized.

Pehea wau e kauoha ai i kā mākou huahana?
He mea maʻalahi loa ke kauoha ʻana i kā mākou huahana kila. Pono ʻoe e hahai i nā ʻanuʻu ma lalo nei:
1. E nānā i kā mākou pūnaewele e ʻike i ka huahana kūpono no kāu mau pono. Hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou ma o ka leka uila, leka uila, WhatsApp, etc. e haʻi iā mākou i kāu mau koi.
2. Ke loaʻa iā mākou kāu noi ʻōlelo, e pane mākou iā ʻoe i loko o 12 mau hola (inā he hopena pule, e pane koke mākou iā ʻoe i ka Pōʻakahi). Inā wikiwiki ʻoe e kiʻi i kahi ʻōlelo, hiki iā ʻoe ke kelepona iā mākou a kamaʻilio pū me mākou ma ka pūnaewele a e pane mākou i kāu mau nīnau a hāʻawi iā ʻoe i ka ʻike hou aku.
3.E hōʻoia i nā kiko'ī o ke kauoha, e like me keʻano huahana, ka nui (e hoʻomaka pinepine ana mai kahi pahu, e pili ana i 28tons), ke kumukūʻai, ka manawa hoʻouna, nā hua'ōlelo uku, a me nā mea'ē aʻe.
4.E hana i ka uku, e hoʻomaka mākou i ka hana i ka wā hiki loa, eʻae mākou i nāʻano uku uku, e like me: hoʻoili kelepona, leka hōʻai'ē, etc.
5. Loaʻa i nā waiwai a nānā i ka maikaʻi a me ka nui. Hoʻopili a hoʻouna aku iā ʻoe e like me kāu koi. E hāʻawi pū mākou i ka lawelawe ma hope o ke kūʻai aku iā ʻoe.
Ka manawa hoʻouna: Mei-29-2025
