Paipu kaulahao
ʻO ka wehewehe pōkole:
ʻO ka paipu galvanized, i ʻike ʻia ʻo galvanized steel pipe, ua māhele ʻia i ka galvanizing hot-dip a me ka electro galvanizing.He mānoanoa ka papa galvanizing wela a loaʻa iā ia nā mea maikaʻi o ka uhi like ʻole, ka hoʻopili ikaika a me ke ola lawelawe lōʻihi.He haʻahaʻa ke kumukūʻai o ka electro galvanizing, ʻaʻole maʻalahi ka ʻili, a ʻoi aku ka maikaʻi o kona pale ʻana i ka corrosion ma mua o ka paipu galvanized wela.
Paipu galvanized wela
ʻO ia ka hana ʻana o ka metala i hoʻoheheʻe ʻia me ka matrix hao e hana i kahi ʻāpana paʻa, i hui pū ai ka matrix a me ka uhi.Hot dip galvanizing mea e pickle mua ka paipu kila.I mea e wehe ai i ka hao oxide ma luna o ka ʻili o ka paipu kila, ma hope o ka pickling, ua hoʻomaʻemaʻe ʻia i loko o ka ammonium chloride a i ʻole zinc chloride aqueous solution a i ʻole ammonium chloride a me ka zinc chloride i hui pū ʻia i ka pahu wai wai, a laila hoʻouna ʻia i ka pahu galvanizing wai wela.Loaʻa i ka Hot dip galvanizing nā mea maikaʻi o ka uhi ʻaʻahu, ka hoʻopili ikaika a me ke ola lawelawe lōʻihi.ʻO ka hapa nui o nā kaʻina hana ma ka ʻĀkau e hoʻohana i ke kaʻina o ka paipu ʻōwili pololei me ke kaula galvanized no ka hoʻohui zinc.
