ʻO ka hao hao hao wela

ʻO nā paipu kila kila he mau paipu kila i hoʻopaʻa ʻia me ka wela-dip galvanized a i ʻole electro-galvanized papa ma luna o ka ʻili.Hiki i ka Galvanizing ke hoʻonui i ka pale ʻana o ka paipu kila a hoʻolōʻihi i kona ola lawelawe.He nui ka hoohana ana o na paipu Galvanized.Ma waho aʻe o nā paipu laina no ka lawe ʻana i ka wai, ke kinoea, ka aila a me nā wai haʻahaʻa haʻahaʻa maʻamau, hoʻohana ʻia lākou e like me nā paipu aila a me nā paipu aila i loko o ka ʻoihana ʻaila, ʻoi aku ka nui o nā ʻaila o waho, a me nā mea hoʻomehana aila a me ka condensate no ka coking kemika. mea lako.ʻO nā paipu no nā mea hoʻoluʻu, nā mea hoʻololi aila holoi i hoʻoheheʻe ʻia me ka lanahu, nā puʻu paipu no nā alahaka trestle, nā paipu no nā papa kākoʻo o koʻu mau tunnels, etc.

ʻO ka paipu galvanized wela e hana i ka metala i hoʻoheheʻe ʻia a me ka matrix hao e hana i kahi ʻāpana alloy, i hui ʻia ka matrix 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 luna o ka ʻili o ka paipu kila, ma hope o ka pickling, hoʻomaʻemaʻe ʻia i loko o kahi pahu o ka ammonium chloride a i ʻole ka zinc chloride aqueous solution a i ʻole ka hui ʻana o ka wai o ka ammonium chloride a me ka zinc chloride, a laila hoʻouna ʻia i In ka pahu hoʻopaʻa 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.ʻO ka matrix o ka paipu kila hoʻoheheʻe wela e loaʻa i ka hopena kino a me ke kemika me ka hoʻoheheʻe hoʻoheheʻe hoʻoheheʻe ʻia e hana i kahi ʻāpana zinc-hao me ka paʻa paʻa.Hoʻohui ʻia ka ʻāpana alloy me ka papa zinc maʻemaʻe a me ka matrix paipu kila, no laila ua ikaika kona kūpaʻa corrosion.
