ʻO ka pauka Chromium kahi pauka metala maʻamau, hoʻohana nui ʻia i ka hana ʻana i nā ʻano mea ikaika kiʻekiʻe, corrosion-resistant alloys a me nā huahana.

Hoʻokomo i ka pauka chromium

ʻO ka pauka Chromium he pauka metala i hana ʻia me ka chromium, ʻo ka molecular formula Cr, ʻo ke kaumaha molekala he 51.99.He ʻano maikaʻi, ʻoluʻolu kona helehelena, kālā keʻokeʻo a hina paha, paʻakikī loa.ʻO ka pauka Chromium kahi pauka metala koʻikoʻi, i hoʻohana nui ʻia i ka hana ʻana, uila, aerospace a me nā ʻano ʻē aʻe.

Ka waiwai kino a me ke kemika o ka pauda chromium

ʻO nā waiwai kino o ka pauka chromium e pili ana i ke kiʻekiʻe kiʻekiʻe, ka conductivity uila maikaʻi a me ke kūpaʻa corrosion.Loaʻa iā ia ka nui o 7.2g / cm3, kahi heheʻe o 1857 ° C a me kahi paila o 2672 ° C. ʻAʻole maʻalahi ka pauka Chromium i ka oxidize i ka lumi wela, maikaʻi ke kūpaʻa corrosion, hiki ke pale i ka waikawa, alkali, paʻakai a me ka paʻakai. ʻino nā mea kemika ʻē aʻe.

ʻO nā waiwai kemika o ka pauka chromium he ʻano hana a hiki ke hana me nā ʻano mea kemika.No ka laʻana, hiki i ka pauka chromium ke hana me ka wai e hana i ka chromium hydroxide a hāʻawi i ka hydrogen.Eia hou, hiki i ka pauka chromium ke hana me ka nui o ka oxidants a hiki ke hoʻoheheʻe ʻia i trivalent chromium ion.

Ke ʻano o ka hoʻomākaukau ʻana i ka pauka chromium

ʻO ke ʻano o ka hoʻomākaukau ʻana o ka pauka chromium ka nui o ke ʻano electrolysis, ke ʻano hoʻohaʻahaʻa a me ke ʻano o ka oxidation.ʻO ka electrolysis kahi hana hoʻomākaukau maʻamau no ka loaʻa ʻana o ka pauka chromium ma o ka electrolysis o ka hopena paʻakai chromium i ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe.ʻO ke ʻano hoʻohaʻahaʻa, ʻo ia ka hana ʻana i ka chromium ore me ke kalapona i ka wela kiʻekiʻe e hana i ka chromium carbide, a laila e uhaʻi iā ia e kiʻi i ka pauka chromium.ʻO ke ʻano o ka oxidation ʻo ia ka hoʻohaʻahaʻa ʻana o ka chromium oxide i ka wela kiʻekiʻe e hana i ka pauka chromium.Loaʻa i nā ʻano hana like ʻole nā ​​pono a me nā hemahema, a pono ke koho ʻia ke ʻano hoʻomākaukau kūpono e like me nā pono.

Nā wahi noi o ka pauka chromium

He ākea loa nā kahua noi o ka pauka chromium, ʻo ia hoʻi me ka hoʻoili metala non-ferrous, nā mea kūkulu hale, ka uhi mua ʻana, ka ʻoihana pākaukau a pēlā aku.Ma ke kahua o ka hana metala non-ferrous, hiki ke hoʻohana ʻia ka pauka chromium e hana i nā ʻano like ʻole o ka ikaika kiʻekiʻe, corrosion-resistant alloys a me nā huahana, e like me ke kila kila, ke kila kila, ke kila kiʻekiʻe a pēlā aku.Ma ke kahua o nā mea kūkulu hale, hiki ke hoʻohana ʻia ka pauka chromium e hana i nā ʻano ʻano corrosion-resistant, kiʻekiʻe-mehana ceramic a me nā huahana aniani.Ma ke kahua o ka uhi ʻana i ka pretreatment, hiki ke hoʻohana ʻia ka pauka chromium e hana i nā mea hoʻololi kemika like ʻole, e like me nā mea hoʻololi chromate a me nā mea hoʻololi phosphate.I ka ʻoihana pākaukau, hiki ke hoʻohana ʻia ka pauka chromium no ka hana ʻana i nā mea uila electrode like ʻole, e like me nā pihi nickel-cadmium a me nā ʻāpana nickel-metal hydride.

Ka palekana o ka pauka Chromium a me ka pale kaiapuni

ʻO ka pauka Chromium he mea weliweli, hiki i ka hoʻolaha lōʻihi ke kumu i ka huhū a me ka pōʻino i ka ʻili kanaka, nā maka a me ka ʻōnaehana hanu, a i nā hihia koʻikoʻi hiki ke alakaʻi i ka maʻi kanesa.No laila, i ka hana ʻana, ka hoʻohana ʻana a me ka mālama ʻana i ka pauka chromium, pono e hoʻokō pono i nā kaʻina hana palekana kūpono a me nā hoʻoponopono kaiapuni.I ka manawa like, pono e hoʻohana ʻia nā ʻano hoʻolei ʻōpala kūpono, e like me ke kanu hohonu, incineration a i ʻole ka mālama kemika, e hōʻemi i ka hopena i ke kaiapuni a me ke olakino kanaka.

I ka pōkole, ʻo ka pauka chromium he pauka metala koʻikoʻi, me ka nui o ka hoʻohana a me ka waiwai waiwai nui.Ma hope o ka hoʻomaopopo ʻana i kāna mau waiwai kumu, nā ʻano hoʻomākaukau, nā kahua noi a me nā pilikia palekana a me ka palekana o ke kaiapuni, hiki iā mākou ke hoʻomaopopo maikaʻi i kāna ʻike pili a me ka noi.I ka manawa like, pono mākou e hoʻolohe i ka mālama ʻana i ke kaiapuni a me ke olakino kanaka, a e hōʻemi i ka hopena i ke kaiapuni a me nā kānaka.
