Huahana Huahana
Hoʻopili ʻia ka pahu kila i hoʻopaʻa ʻia ʻo Chrome me kahi ʻāpana metala ma ka ʻili o ka metala kila ma o ka electroplating.ʻO ke kumu nui o nā paipu kila i hoʻopaʻa ʻia i ka chromium ʻo ia ka pale ʻana iā lākou.ʻO nā paipu kila i hoʻopaʻa ʻia ʻo Chromium he paʻa kemika maikaʻi a ʻaʻole hoʻololi i ka alkali, sulfides, a me ka hapa nui o nā waikawa organik.Hiki ke hoʻoheheʻe ʻia nā paipu kila chromium i loko o ka waika hydrochloride (e like me) a me ka wela.ʻO ka lua, ʻoi aku ka maikaʻi o ka pale ʻana o ka chromium plating, a ʻo nā paipu kila chromium plated wale nō ka oxidize a me ka discolor ke ʻoi aku ka mahana ma mua o 500 degere Celsius.A ʻo kāna ʻāpana friction, ʻoi aku ka nui o ka friction coefficient, i waena o nā metala āpau, a ʻo nā paipu kila i hoʻopaʻa ʻia i ka chrome he kūpaʻa maikaʻi loa.Ma ka laula kukui ʻike ʻia, ʻo ka hiki ke noʻonoʻo o ka chromium ma kahi o 65%, ma waena o ke kālā (88%) a me ka nickel (55%).ʻAʻole hoʻololi ka Chromium i ke kala, a hiki i nā paipu kila i hoʻopaʻa ʻia i ka chrome ke mālama i ko lākou hiki ke noʻonoʻo no ka manawa lōʻihi ke hoʻohana ʻia, ʻoi aku ka maikaʻi ma mua o ke kālā a me ka nickel.

| Hoʻopili: | No nā lāʻau, ʻo ka puʻupuʻu he pale lima pahu pahu + pahu lāʻau kūpono i ke kai. |
Hoʻohana pinepine ʻia nā paipu kila i hoʻopaʻa ʻia i ka chromium no nā paipu kila ʻole i ka nui a me nā hana mechanical;Hoʻohana ʻia kekahi no ka lawe ʻana i nā paipu kila chrome plated, kūpono loa no ka lawe ʻana i nā wai e like me ka wai, ka aila, ke kinoea, a me nā mea ʻē aʻe. nā paipu a me nā paipu wai hoʻolapalapa no nā paila haʻahaʻa a me waena o nā hui like ʻole, a me ka carbon structural steel hot rolled a me ke anu huki seamless steel tubes no nā paipu mahu Superheated, nā puʻupuʻu uahi, nā paipu uwahi liʻiliʻi a me nā paipu pōhaku lepo no nā paila locomotive;I loko o nā paila kīʻaha kiʻekiʻe, hoʻohana nui ʻia nā paipu kila i hoʻopaʻa ʻia i ka chromium no ka hana ʻana i ke kila kalapona maʻemaʻe a me ke kila kila kila ʻili wela no ka ʻili wela o ka puʻu wai kiʻekiʻe a ma luna o ke kaomi.
I ka hoʻohana ʻana i nā mea hoʻomomona, aia nā koi maʻamau no ka mahana a me ke kaomi o ka hana Douay;I ka petroleum māhā, ua kūpono no ka seamless kila paipu, wela ex-changers, a me pipelines i ka aila hoʻomaʻemaʻe mea kanu;Eia kekahi, he mea koʻikoʻi ka hoʻohana ʻana i nā capillaries stainless steel i nā ʻano he nui e like me ka hoʻoheheʻe ʻana i ka honua, ka hoʻoheheʻe ʻana i ka daimana, a me ka hoʻohana ʻana i nā paipu wili ʻaila.
