Me ka holomua mau o ke kaiāulu, ʻaʻole hiki i ke ʻano hana mahiʻai kuʻuna ke hoʻokō hou i nā pono o ka hoʻomohala ʻana o ka nohona hou, a ke ʻimi ʻia nei ka hale mahiʻai hou e ka poʻe o ka ʻoihana. ʻO ka ʻoiaʻiʻo, ʻo ka mea i kapa ʻia he lako mahiʻai, ʻo ia nā hale ʻōmaʻomaʻo. ʻAʻole ia i kaupalena ʻia e ka manawa a me ka wahi. Hiki iā ia ke hana i ka hana mahiʻai ma nā wahi kūikawā e like me ka pāpū, nā mauna hohonu a me ka wao nahele. Ma ke ʻano he kumu o ka papahana ʻōmaʻomaʻo, pono e kāohi nā mea i ka maikaʻi o ka papahana, ʻo ka mea mua, mai ke koho ʻana i nā mea. No ka laʻana, no nā ʻāpana kila i hoʻohana ʻia i ka papahana ʻōmaʻomaʻo, e hana ʻia a wehe ʻia ke kila kiʻekiʻe. Ma hope o ka uhi wela ʻana i loko o kahi hale hana galvanizing ʻoihana, e hoʻāʻo hou ka ʻoihana nānā maikaʻi. Ma hope o ka hala ʻana i ka hoʻāʻo, e lawe ʻia i ke kahua kūkulu no ka hoʻohana ʻana.

1. ʻAno paipu kila galvanized wela: ʻO ka paipu galvanized wela ka mea e hana ai i ka metala hoʻoheheʻe e hana me ka matrix hao e hana i kahi papa alloy, i mea e hui pū ai ka matrix a me ka uhi ʻana. Hoʻomoʻa mua ʻia ka paipu galvanized wela i hāʻawi ʻia e Tianjin Feilong Pipe Co., Ltd. I mea e wehe ai i ka hao oxide ma luna o ka ʻili o ka paipu kila, ma hope o ka pickling, hoʻomaʻemaʻe ʻia i loko o ka ammonium chloride a i ʻole ka zinc chloride aqueous solution a i ʻole ka ammonium chloride a me ka zinc chloride i hui ʻia i loko o ka pahu wai solution, a laila hoʻouna ʻia i ka pahu galvanizing wela. Loaʻa i ka galvanizing wela nā pono o ka uhi like, ka hoʻopili ikaika a me ke ola lawelawe lōʻihi. Loaʻa i ka matrix o ka paipu kila galvanized wela nā hopena kino a me ke kemika paʻakikī me ka hopena plating hoʻoheheʻe e hana i kahi papa zinc ferroalloy pale corrosion me ka hoʻonohonoho paʻa. Hoʻohui ʻia ka papa alloy me ka papa zinc maʻemaʻe a me ka matrix paipu kila. No laila, he kūpaʻa ikaika kona.

2. ʻAno paipu ʻāpana galvanized: hoʻoponopono ka paipu ʻāpana galvanized i ke kaʻina hana o ka paipu galvanized wela-luʻu. ʻO ka mea mua, e hoʻomoʻa ʻia ke kila ʻāpana i hoʻohana ʻia no ka hana ʻana i nā paipu e wehe i ka hao oxide ma ka ʻili o ke kila ʻāpana. A laila e hoʻomaloʻo i ka ea a hana i paipu. He like a ʻālohilohi ka uhi ʻana, a he liʻiliʻi ka nui o ka uhi zinc, ʻoi aku ka haʻahaʻa ma mua o ke kumukūʻai o ka hana ʻana i ka paipu galvanized wela-luʻu. ʻOi aku ka ʻino o kona kūpaʻa i ka pala ma mua o ka paipu galvanized wela-luʻu
