ʻO ka pauda daimana ʻāina me nā | ʻano daimana aniani hoʻokahi e like me ka mea maka, akā | ʻano maʻiʻo haumia kiʻekiʻe, ikaika haʻahaʻa, hiki ke hoʻohana wale ʻia i ka noi huahana mākeke haʻahaʻa. Hoʻohana kekahi mau mea hana lepo daimana i ka ʻano I1 a i ʻole Sichuan type one crystal diamond ma ke ʻano he mea maka no ka hana ʻana i ka pauka daimana, ʻoi aku ka nui o kāna hana ʻana i ka pauka daimana maʻamau, hiki ke hoʻokō i ka koi o ka mākeke kiʻekiʻe. ʻO ka pauka daimana kiʻekiʻe paʻakikī, maikaʻi ke pale ʻana i ka lole, hoʻohana nui ʻia i ka ʻoki ʻana, wili, wili, polishing a me nā māla ʻē aʻe. Me ka hoʻomohala ʻana a me ka holomua o ka ʻepekema a me ka ʻenehana, ʻoi aku ka nui o ka mākeke no ka pauka daimana, a ʻoi aku ka kiʻekiʻe o nā koi o ka maikaʻi. No ka pauda daimana, pili pono ka nui o nā haumia i ka pauda daimana i ka maikaʻi o ka huahana a me ka hana o ka pauda.
ʻAno hoʻopau
ʻO nā mea haumia o ka pauka daimana e pili ana i nā ʻāpana kalapona ʻole i ka pauka daimana, hiki ke hoʻokaʻawale ʻia i loko o nā mea haumia o waho a me nā haumia o loko. Hoʻokomo nui ʻia nā mea haumia o waho e nā mea maka a me nā kaʻina hana, e like me ke silika, hao, nickel, calcium, magnesium a me cadmium; ua hoʻokomo ʻia nā mea ʻino o loko o nā ʻāpana i loko o ke kaʻina hana synthesis o ka daimana, ka mea nui e pili ana i ka hao, nickel, cobalt, manganese, cadmium, copper, etc. ʻO nā haumia i loko o ka pauka daimana e hoʻopili i nā waiwai ili o nā ʻāpana pauka, no laila ʻaʻole maʻalahi ka huahana e hoʻopuehu. ʻO ka hao, ka nickel a me nā mea haumia ʻē aʻe e hana i ka huahana i nā degere like ʻole o ka magnetism, ka noi ʻana o ka pauka.
, ʻano ʻike haumia
Nui nā ʻano hana ʻike haumia o ka pauka daimana, me ke ʻano kaumaha, atomic emission spectroscopy, atomic absorption spectroscopy, etc., hiki ke koho ʻia nā ʻano ʻike like ʻole e like me nā koi like ʻole.
kālaihelu gravimetric
He kūpono ke ʻano paona no ka nānā ʻana a me ka ʻike ʻana i ka nui o nā maʻiʻo haumia (koe ʻole nā mea hoʻoheheʻe ʻia i ka wela wela). ʻO nā mea hana nui e pili ana i ka umu mafer, analytical balance, porcelain crucible, dryer, etc. ʻO ke ʻano hoʻāʻo no ka ʻike haumia i loko o ka micropowder huahana maʻamau he kiʻekiʻe wela wela ke ʻano o ka hoʻopau ʻana: hāpana e like me nā mea i hoʻolako ʻia a lawe i ka hāpana hoʻāʻo i loko o ka crucible me ke kaumaha mau, kau i ka crucible i loko o ka hāpana e hoʻāʻo ʻia i loko o ka umu i ʻae ʻia i ke koena 100 ℃ , ʻae ʻia i ke koena 100 ℃. ʻO ke kaumaha ka nuipaʻa like ʻole, a ua helu ʻia ka pākēneka kaumaha.
2, atomic emission spectrometry, atomic absorption spectroscopy
ʻO ka spectroscopy hoʻokuʻu atomika a me ka spectroscopy absorption atomika kūpono i ka qualitative a me ka quantitative analysis of trace elements.
(1) Atomic emission spectrometry: he ʻano analytical no ka qualitative a quantitative analysis o ka laina radiation hiʻona i hana ʻia e ka hoʻololi electron mai ka ikehu waho o nā mea kemika. ʻO ke ʻano hoʻokuʻu atomika hiki ke hoʻopaʻa ʻia ma kahi o 70 mau mea. Ma keʻano laulā, hiki i ke ana ʻana o nā ʻāpana ma lalo o 1% ke ana pololei i ka pae ppm me nā mea i loko o ka pauka daimana. ʻO kēia kaʻina hana mua loa i hana ʻia a hoʻomohala ʻia i ka nānā ʻana i ka optical. He kuleana koʻikoʻi ko Atomic emission spectrometry i ka qualitative a quantitative analysis o nā ʻano mea hou. Loaʻa iā ia nā mea maikaʻi o ka hiki ke ʻike i ka manawa like, ka wikiwiki loiloi wikiwiki, ka palena haʻahaʻa haʻahaʻa a me ka pololei kiʻekiʻe.
(2) Atomic absorption spectroscopy: ke hele ka radiation emited by a specific light source in the atomic vapor of the element e ana ana, ua komo ia e ka honua moku'āina atoms, a hiki ke ana i ke ana o ka absorption degere no ka anaana elemental.
Atomic absorption spectrometry a hiki ke hoʻokō kekahi i kekahi a ʻaʻole hiki ke pani ʻia kekahi me kekahi.
3. Nā mea e pili ana i nā ana o nā haumia
1. Ka hopena o ka nui o ka laʻana i ka waiwai hoʻāʻo
I ka hoʻomaʻamaʻa ʻana, ʻike ʻia ka nui o ka laʻana o ka pauka daimana i ka hopena nui i nā hopena hōʻike. Ke 0.50g ka nui o ka laʻana, nui ka awelika o ka hoʻāʻo; inā he 1.00g ka nui o ka laʻana, he liʻiliʻi ka awelika deviation; i ka 2.00g ka nui o ka laʻana, ʻoiai he liʻiliʻi ka deviation, piʻi ka manawa hoʻāʻo a hoʻemi ka pono. No laila, i ka wā o ke ana ʻana, ʻaʻole pono e hoʻomaikaʻi i ka pololei a me ka paʻa o ka hopena o ka nānā ʻana, akā e hoʻolōʻihi i ka manawa hana a hōʻemi i ka pono hana.
2. ʻO ka mana o ka nui o ka ʻāpana ʻāpana ma luna o ka ʻike haumia
ʻOi aku ka maikaʻi o ka pauda daimana, ʻoi aku ka kiʻekiʻe o ka haumia o ka pauda. ʻO ka nui o ka nui o ka 3um i loko o ka pauka daimana maikaʻi i ka hana ʻana, ma muli o ka nui o ka nui o ka ʻāpana, ʻaʻole maʻalahi ka hoʻokaʻawale ʻana o kekahi mau mea waika a me nā kumu i hui pū ʻia me nā mea maka, no laila e hoʻonoho ʻia i loko o ka pauka lepo maikaʻi, no laila e hoʻonui ai i ka ʻike o nā haumia. Eia kekahi, ʻoi aku ka maikaʻi o ka nui o ka ʻāpana, ʻoi aku ka maikaʻi o ka hana ʻana, ʻoi aku ka nui o nā haumia i waho, e like me ka dispersant, ka hoʻonā wai, ka hana ʻana o ka lepo lepo haumia haumia i loko o ke aʻo ʻana i ka pauka hāpana impurity hoʻāʻo ʻana, ua ʻike mākou ʻoi aku ma mua o 95% o nā huahana pauka daimana coarse-grained. 1.00%. No laila, i ka mana o ka pauda maikaʻi, pono e emi ka pauda maikaʻi ma mua o 1.00%; ʻo ka mea haumia o 3um pono e emi iho ma mua o 0.50%; a e mālama ʻia ʻelua mau wahi decimal ma hope o ka ʻikepili maʻiʻo haumia i ka maʻamau. No ka mea me ka holomua o ka ʻenehana hana pauka, e hoʻemi iki ʻia ka ʻike haumia i loko o ka pauka, ʻo ka hapa nui o ka pauka lepo ma lalo o 0.10%, inā hoʻokahi wale nō wahi decimal, ʻaʻole hiki ke ʻike maikaʻi ʻia kona ʻano.
