He kiʻekiʻe loa ka nui o ka zinc plating, ʻoi aku ka mānoanoa o ka zinc coating ma mua o 65 microns, a ʻokoʻa kona kūpaʻa corrosion ma mua o ka paipu galvanized wela.Hiki i ka mea hana paipu galvanized maʻamau ke hoʻohana i ka paipu galvanized anuanu e like me ka wai a me ka paipu kinoea.ʻO ka uhi zinc o ka paipu kila galvanized anuanu he papa electroplated, a ua hoʻokaʻawale ʻia ka papa zinc mai ka substrate paipu kila.He lahilahi a maʻalahi ka hāʻule ʻana o ka papa zinc no ka mea ua hoʻopili ʻia i ka substrate paipu kila.No laila, ʻilihune kona pale ʻana i ka corrosion.ʻAʻole ʻae ʻia ka hoʻohana ʻana i ka paipu kila galvanized ma ke ʻano he paipu kila wai i nā hale noho hou.

Hoʻohana nui ʻia ka paipu kila Galvanized i ke kūkulu ʻana, nā mīkini, nā koina lanahu, ʻoihana kemika, mana uila, nā kaʻa kaʻaahi, ʻoihana kaʻa, alaloa, alahaka, ipu, nā hale haʻuki, nā mīkini mahiʻai, nā mīkini ʻaila, nā mīkini ʻimi a me nā ʻoihana hana ʻē aʻe.

ʻO ka paipu kila hoʻoheheʻe wela: ʻo ia ka hoʻoheheʻe ʻana o ka metala i hoʻoheheʻe ʻia me ka matrix hao e hana ai i ka papa paʻa, i hui ʻia ka matrix a me ka uhi.I mea e wehe ai i ka hao oxide ma ka ʻili o ka paipu kila, ma hope o ka pickling, hoʻomaʻemaʻe ʻia ka paipu kila e ka ammonium chloride a i ʻole ka zinc chloride aqueous solution a i ʻole ka pahu hoʻonā hui ʻia o ka ammonium chloride a me ka zinc chloride, a laila hoʻouna ʻia i ka pahu galvanizing hot-dip.Loaʻa i ka Hot dip galvanizing nā mea maikaʻi o ka uhi ʻaʻahu, ka hoʻopili ikaika a me ke ola lawelawe lōʻihi.ʻO nā hopena kino a me ke kemika paʻakikī ma waena o ka substrate o ka paipu kila galvanized wela a me ka ʻauʻau hoʻoheheʻe e alakaʻi i ka hoʻokumu ʻana i kahi papa zinc ferroalloy me kahi hoʻolālā kūʻē corrosion.Hoʻohui ʻia ka ʻāpana alloy me ka ʻāpana zinc maʻemaʻe a me ka matrix paipu kila, no laila ua ikaika kona pale ʻana i ka corrosion.

Cold galvanized kila paipu: anu galvanized paipu he electro galvanized, ka nui o ka zinc plating wale 10-50g / m2, a me kona corrosion kū'ē ua nui okoa mai ka wela-hoʻohuʻu galvanized paipu.I mea e hōʻoia ai i ka maikaʻi, ʻaʻole hoʻohana ka hapa nui o nā mea hana paipu galvanized maʻamau i ka electro galvanizing (cold plating).ʻO kēlā mau mea liʻiliʻi liʻiliʻi, nā mea kahiko o nā ʻoihana liʻiliʻi e hoʻohana i ka galvanizing, ʻoiaʻiʻo, ʻoi aku ka liʻiliʻi o kā lākou kumukūʻai.Ua hoʻolaha kūkala ke Kuhina o ke kūkulu hale i ka hoʻopau ʻia ʻana o nā paipu galvanized anuanu, ʻaʻole ʻae ʻia ka hoʻohana ʻana i nā paipu galvanized anuanu e like me nā paipu wai a me ke kinoea.ʻO ka uhi zinc o ka paipu kila galvanized anuanu he papa electroplated, a ua hoʻokaʻawale ʻia ka papa zinc mai ka substrate paipu kila.He lahilahi a maʻalahi ka hāʻule ʻana o ka papa zinc no ka mea ua hoʻopili ʻia i ka substrate paipu kila.No laila, ʻilihune kona pale ʻana i ka corrosion.ʻAʻole ʻae ʻia ka hoʻohana ʻana i ka paipu kila galvanized ma ke ʻano he paipu wai i nā hale noho hou.
