Paipu kila maʻemaʻe ʻole
ʻO ka wehewehe pōkole:
He liʻiliʻi loa ka nui o ka paipu galvanized seamless, ʻo 10-50g / m2 wale nō, a ʻokoʻa loa kona kūpaʻa corrosion mai ka paipu galvanized wela.Ua ʻae ʻia nā mea hana paipu galvanized maʻamau e hoʻohana i nā paipu galvanized anuanu e like me nā paipu wai a me ke kinoea.ʻO ka papa galvanized o ke anuanu galvanized steel pipe he electroplating layer, a ua hoʻokaʻawale ʻia ka papa zinc mai ka substrate paipu kila.He lahilahi ka papa zinc, a ua hoʻopili wale ʻia ka papa zinc i ka matrix pipe kila, kahi maʻalahi e hāʻule.No laila, ʻilihune kona pale ʻana i ka corrosion.I nā hale hou, pāpā ʻia ka hoʻohana ʻana i nā paipu kila galvanized anuanu e like me nā paipu kila wai.
Ma hope o ka pickling, hoʻomaʻemaʻe ʻia nā paipu kila kila ʻole i ka ammonium chloride a i ʻole zinc chloride aqueous solution a i ʻole ammonium chloride a me ka zinc chloride i hui pū ʻia me ka pahu wai wai.I mea e hōʻoia ai i ka maikaʻi, ʻaʻole hoʻohana ʻia ka electro galvanizing (cold plating).ʻO kēlā mau ʻoihana liʻiliʻi wale nō me nā mea liʻiliʻi a me nā mea kahiko e hoʻohana i ka electro galvanizing, ʻoiaʻiʻo, ʻoi aku ka maʻalahi o kā lākou kumukūʻai.Ua kāpae ʻia ke Kuhina o ke kūkulu ʻana i ka paipu galvanized i hope, ʻaʻole ia e lilo i electro galvanized i ka wā e hiki mai ana.ʻO ia ka hana ʻana i ka metala hoʻoheheʻe ʻia me ka hao e hana ai i kahi ʻāpana huila, i hui pū ai ka matrix a me ka uhi.ʻO ka hoʻoheheʻe wela wela, ʻo ia ka ʻoki ʻana i ka paipu kila ma mua, i mea e wehe ai i ka hao okisa ma ka ʻili o ka paipu kila, a laila e hoʻouna i ka pahu galvanizing wela.Loaʻa i ka Hot dip galvanizing nā mea maikaʻi o ka uhi ʻaʻahu, ka hoʻopili ikaika a me ke ola lawelawe lōʻihi.
