Uila/Hot-dip galvanized paipu kila
Paipu kila galvanizedhe paipu kila kalapona i uhi ʻia me kahi papa pale o ka zinc.Hana ʻia ka ʻāpana zinc ma ke ʻano he ʻāpana mōhai, e lilo ia i ka pala ma mua o ke kila kalapona ma lalo iho.ʻElua ʻano ʻano paipu hao hao ʻelua: ʻo ka paipu kila puʻupuʻu wela a me ka paipu kila galvanized anuanu.E hoʻoikaika ka papa galvanized i nā hana anti-corrosion o nā paipu kila.
ʻO ka galvanizing wela ka hana ʻana i ka metala i hoʻoheheʻe ʻia a me ka hoʻoheheʻe ʻana o ka matrix hao ma ke ʻano he papa hoʻoheheʻe, i hui ʻia ke substrate a me ka uhi ʻelua.ʻO ka hoʻoheheʻe wela wela e ʻoki mua i ka paipu kila, i mea e wehe ai i ka hao hao ma ka ʻili o ka paipu kila.Ma hope o ka pickling, ma o ka ammonium chloride a i ʻole ka zinc chloride aqueous solution a i ʻole ammonium chloride a me ka zinc chloride i hui pū ʻia i ka pahu wai wai no ka hoʻomaʻemaʻe ʻana, a laila i loko o ka pahu wela wela.Loaʻa i ka Hot-dip galvanizing ka maikaʻi o ka hoʻopaʻa ʻana i ka lole, ka hoʻopili ikaika a me ke ola lawelawe lōʻihi.Hiki ke hāʻawi ʻia ka lāʻau uila galvanized me ka māmā & nani.
Ke kaʻina hana galvanizing wela:
ʻO ka mea hana degreasing → holoi → pickling → holoi → hoʻomaloʻo i ka solvent dip fluxing preheated hot dip galvanized → hoʻomaha → hoʻopau → holoi → hoʻomaloʻo → hoʻāʻo passivation
Kaʻina galvanized anuanu:
Hoʻomaʻemaʻe kemika → holoi → wai wela ka wai wela electrolysis degreasing → holoi → holoi → hoʻoheheʻe hao galvanized ikaika → holoi → holoi → māmā → holoi → hoʻomaloʻo passivation
Mea kūkulu hale a me ka hale
Mechanical and general engineering kumu
Ka hana ʻana i ke kino kaʻa
