3. No ke aha i hoʻohana nui ʻia ai ka Platinum?
Hoʻohana nui ʻia ka Platinum no ka mea ua hui pū ʻia kekahi mau waiwai i ʻike ʻole ʻia i loko o ka metala hoʻokahi.
Hana Catalytic Kūikawā
ʻO Platinum kekahi o nā metala catalytic koʻikoʻi i hoʻohana ʻia i ka ʻoihana hou.
Hiki i kona ʻili ke hoʻomaʻamaʻa i nā hopena ma o ka hāʻawi ʻana i nā wahi hana e hoʻohaʻahaʻa i ka pale ikehu kūpono no nā ala ʻae kikoʻī, ʻoiai ʻaʻole hoʻopau ʻia ka platinum ponoʻī i ka hopena holoʻokoʻa ma ke ʻano like me ka reactant.
He mea koʻikoʻi kēia i ka platinum ke koi ʻia kahi kaʻina hana catalytic kiʻekiʻe, kūlohelohe, a me ke kū'ē i ka hoʻohaʻahaʻa kemika.
ʻO kāna mau waiwai catalytic e kākoʻo ana i nā noi i ka mana hoʻokuʻu automotive, hoʻoheheʻe ʻaila, hana kemika, ʻenehana hydrogen, a me nā wahie.
Kūleʻa Kūʻē Kūʻē Kūʻē
Hōʻike ka Platinum i ke kūpaʻa maikaʻi loa i ka oxidation, ʻinoʻino, a me ka corrosion ma lalo o kahi ākea o nā kūlana kemika a me ke kaiapuni.
Paʻa mau ia i ka ea a kūpaʻa i ka nui o nā waikawa a me nā pāpaʻi koʻikoʻi, ʻoiai ʻaʻole ia he inert loa; ʻo kahi laʻana, hiki ke hoʻoheheʻe ʻia ka platinum e aqua regia, he hui pū ʻia o nā waikawa hydrochloric a me nā waikawa nitric.
Hoʻohana pono kēia paʻa kemika i ka platinum i nā mea hana kemika, nā kīʻaha keʻena hana, uila, nā mea lapaʻau, a me nā noi ʻoihana wela kiʻekiʻe.
Inā hiki i ka haumia a i ʻole ka hoʻohaʻahaʻa ʻana i nā mea waiwai ke hoʻopilikia i ka maikaʻi o ka huahana a i ʻole ka hilinaʻi o ka hana, ʻO ke kūʻē ʻana o ka platinum i ka hoʻouka kaua kemika hiki ke hōʻoia i kona kumukūʻai kiʻekiʻe loa.
Kiekie hehee a me ka wela wela
He wahi hehee ko Platinum ma kahi o 1,768° C a he wahi paila ma kahi o 3,825° C, hāʻawi iā ia i ka mana wela maikaʻi loa.
ʻOi aku ka mea nui, ʻO kona kūpaʻa kemika pono i nā mahana kiʻekiʻe e hiki ai i ka platinum a me ka platinum-based alloys e hana i nā wahi kahi e hoʻoheheʻe ʻia ai nā mea maʻamau., e pane me ke kaʻina hana, aiʻole e pōʻino.
He waiwai nui kēia hui ʻana i ka hana aniani, nā ʻōnaehana catalyst kiʻekiʻe, Nā lako hanaʻo Laboratory, thermocouple, a me nā kapuahi ʻenehana kūikawā.
ʻO nā huila Platinum-rhodium, ʻo kahi laʻana, hoʻohana nui ʻia kahi e pono ai ke kūpaʻa kiʻekiʻe a me ka hana mechanical.
Paʻa Uila a me Electrochemical Hana
ʻAʻole ʻo Platinum ka metala hoʻokele uila nui loa - keleawe a me ke kālā, ʻo kahi laʻana, hāʻawi i ka conductivity kiʻekiʻe loa - akā hāʻawi ka platinum i kahi pono ʻē aʻe: paʻa uila a me ka electrochemical i nā kaiapuni koi.
ʻO kona kūpaʻa i ka corrosion a me ka oxidation e hiki ai i nā electrodes platinum, nā poʻe hoʻopaʻapaʻa, a me nā ʻāpana uila kūikawā e mālama i ka hana hilinaʻi i nā manawa lōʻihi.
No laila, hoʻohana ʻia ʻo Platinum i nā sensor electrochemical, nā mea ʻike wela kūʻē, nā electrodes hale hana, wahie-cell catalysts, a me nā mea uila i koho ʻia.
He mea koʻikoʻi kona pilina kūʻē kūʻē me ka wela no ke ana wela pono, ʻoiai ʻo kona kūpaʻa electrochemical e waiwai ai i nā wahi āpau e pono ai ka electrode e hana pono me ka wikiwiki ʻole.
Biocompatibility a me ka Lapaʻau hilinaʻi
Ua hoʻokumu ʻo Platinum a me nā alloys platinum i koho ʻia i ka ʻenehana lapaʻau ma muli o ko lākou pale ʻana i ka corrosion, paʻa electrochemical, a me ka launa pū ʻana me nā pilina olaola i hana ʻia.
He mea koʻikoʻi kēia mau hiʻohiʻona no nā ʻāpana i hiki ke hoʻopaʻa ʻia me nā wai o ke kino a i ʻole ke kino no nā manawa lōʻihi.
No laila hoʻohana ʻia ʻo Platinum i nā electrodes implantable, nā mea pacemaker a me nā mea neurostimulation, na mea ike lapaau, a me kekahi mau noi niho.
Kahi mea hou aʻe, He kuleana koʻikoʻi ko ka platinum ma ke ʻano o nā pūhui platinum e like me cisplatin, ʻoiai ʻaʻole pono e huikau kēia mau pūhui me ka platinum metala.
Nā hiʻohiʻona kiʻekiʻe a me nā ʻano mea ʻokoʻa
Me kahiʻano o kahi e pili ana 21.45 g / cm³, ʻO ka platinum kekahi o nā metala koʻikoʻi o ke kālepa.
Hāʻawi kona kiʻekiʻe kiʻekiʻe i nā mea hoʻonaninani platinum a me nā mea kikoʻī i ke kaumaha kūʻokoʻa a hāʻawi i kona ʻano waiwai i ʻike ʻia..
Hoʻohui ʻia me kona ʻano keʻokeʻo keʻokeʻo, durability, a me ke kūʻē ʻana i ka ʻino, Ua makemake nui kēia ʻano i ka platinum no nā mea nani, wati nani, a me nā huahana premium ʻē aʻe.
I nā noi hana, Akā naʻe,, hiki ke noʻonoʻo ʻia kona kiʻekiʻe kiʻekiʻe, ʻo ia hoʻi, mālama ʻia ka platinum no nā kūlana i ʻoi aku ka nui o kāna mau waiwai ma mua o kona kaumaha a me ke kumu kūʻai.
Rarity, Recycability, a me ka Waiwai Hana Kiekie
He kakaikahi ka Platinum, a ʻo kona hoʻolako ʻia ʻana ma kahi helu liʻiliʻi o nā ʻāpana honua.
Hāʻawi kēia hemahema i kona waiwai, akā, ʻaʻole ʻo ka rarity wale nō e wehewehe i kona koʻikoʻi ʻoihana.
ʻO ke kumu ikaika loa ka hāʻawi ʻana o ka platinum i ka waiwai hana kiʻekiʻe no kēlā me kēia ʻāpana o nā mea i nā noi e like me nā catalysts, uila, nā poʻe hoʻopaʻapaʻa, a me nā alloys kūikawā.
Hoʻonui hou kona ʻano hana hou i kona waiwai ʻoihana. Hiki ke hoʻihoʻi ʻia ka Platinum mai nā catalysts automotive i hoʻopau ʻia, nā mea hoʻoheheʻe ʻoihana, Kōhai, a me nā huahana ʻē aʻe, e ʻae ana i nā metala waiwai e komo hou i ke kaulahao hoʻolako. He mea koʻikoʻi kēia no kahi mea liʻiliʻi a waiwai nui.
4. He aha ka Platinum i hoʻohana ʻia no?
Hoʻohana ʻia ʻo Platinum ma waena o nā ʻoihana ākea no ka mea e hui pū ana i ke kūpaʻa corrosion, hana catalytic, ʻO ka hoʻomauʻana, uila a me ka hana electrochemical, a me biocomokatiboli.
ʻAʻole like me nā metala i koho mua ʻia no ko lākou ikaika kūkulu ʻana a i ʻole ke kumu kūʻai haʻahaʻa, koho pinepine ʻia ka platinum no ka mea hiki iā ia ke hana i nā hana kūikawā ma lalo o ke koi koi, thermal, lako uila, aiʻole nā kūlana olaola.
