Paipu Galvanized Wela
Hoʻopili ka paipu galvanized wela i ka metala i hoʻoheheʻe ʻia me ka pā hao e hana i kahi ʻāpana paʻa, i hui ʻia ka substrate a me ka uhi.ʻO ka galvanizing wela ka hoʻopili mua ʻana i ka paipu kila.I mea e wehe ai i ka hao oxide ma ka ʻili o ka paipu kila, ma hope o ka pickling, hoʻomaʻemaʻe ʻia e ka ammonium chloride a i ʻole ka zinc chloride aqueous solution a i ʻole ka hui ʻana o ka aqueous solution o ka ammonium chloride a me ka zinc chloride, a laila hoʻouna ʻia i ka pahu wela wela. .Loaʻa i ka Hot-dip galvanizing nā mea maikaʻi o ka uhi ʻana i ka lole, ka hoʻopili ikaika a me ke ola lawelawe lōʻihi.Hoʻokomo ʻia ka pāpaʻi paipu kila hoʻoheheʻe wela me ka hoʻoheheʻe hoʻoheheʻe ʻia e hana i kahi ʻāpana zinc-hao me ka paʻa paʻa.Hoʻohui ʻia ka ʻāpana alloy me ka ʻāpana zinc maʻemaʻe a me ka substrate paipu kila, no laila ke kūpaʻa ikaika ka corrosion.
Hoʻohana nui ʻia nā paipu kila wela wela i ke kūkulu ʻana, nā mīkini, nā mine lanahu, nā kemika, nā mana uila, nā kaʻa kaʻaahi, nā ʻoihana kaʻa, nā alaloa, nā alahaka, nā ipu, nā hale haʻuki, nā mīkini mahiʻai, nā mīkini ʻaila, nā mīkini ʻimi, kūkulu hale ʻaina a me nā mea ʻē aʻe. ʻoihana hana.
