Domestic diamond poda nezvimwe | mhando yedhaimani imwe chete yekristaro seyakagadzirwa, asi | mhando yepamusoro yehutsvina yemukati, yakaderera simba, inogona chete kushandiswa mune yakaderera-kuguma musika chigadzirwa chinodiwa. Vagadziri vehupfu hwemadhaimondi epamba vanoshandisa mhando I1 kana Sichuan mhando imwe yekristaro yedhaimondi seyakagadzirwa kugadzira hupfu hwedhaimondi, kushanda kwayo kwakakura zvakanyanya kupfuura yakajairwa dhaimondi poda, inogona kuzadzisa kudiwa kwemusika wepamusoro. Dhaimondi poda yakakwira kuomarara, yakanaka kupfeka kuramba, inoshandiswa zvakanyanya mukucheka, kugaya, kuchera, kukwenenzvera nemimwe minda. Nekuvandudzwa uye kufambira mberi kwesainzi uye tekinoroji, kudiwa kwemusika wehupfu hwedhaimani kuri kuramba kuchikura, uye zvinodiwa zvemhando yepamusoro zviri kuramba zvichikwira. Paupfu hwedhaimondi, huwandu hwekusachena muhupfu hwedhaimondi hunokanganisa zvakananga chigadzirwa chemhando uye kuita kwehupfu.
Diszable marudzi
Kusachena kwedhaimani poda inoreva izvo zvisiri-kabhoni zvikamu muupfu hwedhaimani, izvo zvinogona kukamurwa kuita granular kunze tsvina uye kusvibiswa kwemukati. Kusvibiswa kwekunze kwezvimedu kunonyanya kuunzwa nezvinhu zvakasvibirira uye maitiro ekugadzira, kusanganisira silicon, iron, nickel, calcium, magnesium uye cadmium; kusvibiswa kwemukati kwezvikamu zvinotangwa mukugadzirwa kwedhaimondi, kunyanya kusanganisira simbi, nickel, cobalt, manganese, cadmium, mhangura, etc. Kusvibiswa muupfu hwedhaimondi kuchakanganisa maitiro epamusoro ehupfu hwehupfu, kuitira kuti chigadzirwa chisava nyore kupararira. Simbi, nickel uye kumwe kusvibiswa kuchaitawo kuti chigadzirwa chibudise madhigirii akasiyana emagnetism, kushandiswa kwehupfu.
, Nzira yekuona kusachena
Kune nzira dzakawanda dzekuona kusachena kwehupfu hwedhaimondi, kusanganisira huremu nzira, atomic emission spectroscopy, atomic absorption spectroscopy, nezvimwewo, nzira dzekuona dzakasiyana dzinogona kusarudzwa zvinoenderana nezvinodiwa zvakasiyana.
gravimetric analysis
Nzira yehuremu inokodzera kuongororwa uye kuonekwa kwehuwandu husina kuchena huripo (kusingabatanidzi zvinhu zvinopisa zvinopisa pakupisa kupisa). Midziyo mikuru inosanganisira mafer furnace, analytical balance, porcelain crucible, dryer, etc. Nzira yekuyedza yekusachena kwemukati muiyo micropowder chigadzirwa chiyero ndeye tembiricha yekupisa yekurasikirwa nzira: sampuli zvinoenderana nezvinopihwa uye tora bvunzo sampu mucrucible nehuremu hunogara huchiisa, isa crucible ine sampuli kuti iongororwe muchoto chinobvumidzwa ℃ ℃ 20 ℃), huremu hwasara hwakasiyana-siyana, uye huremu muzana hunoverengerwa.
2, atomic emission spectrometry, atomic absorption spectroscopy
Atomic emission spectroscopy uye atomic absorption spectroscopy inokodzera kuongororwa kwemhando uye kuwanda kwezvinhu zvekutevera.
(1) Atomic emission spectrometry: inzira yekuongorora yemhando kana yehuwandu yekuongorora kwehunhu hwemwaranzi mutsara unogadzirwa nekuchinja kweelectron kubva kunze kwesimba remhando dzakasiyana dzemakemikari. Nzira yeatomic emission inobvumira kuongororwa kwezvikamu makumi manomwe. Kazhinji, kuyerwa kwezvikamu zviri pasi pe1% zvinogona kunyatso kuyera ppm level trace elements mu diamond powder. Iyi nzira ndiyo yekutanga kugadzirwa uye yakagadzirwa mukuongorora kwemaziso. Atomic emission spectrometry inoita basa rakakosha mukuongororwa kwemhando uye kuwanda kwezvinhu zvakasiyana zvemazuva ano. Iyo ine mabhenefiti e-multi-element panguva imwe chete yekuona kugona, kukurumidza kuongorora kukurumidza, yakaderera yekuona muganho uye yakakwirira kunyatso.
(2) Atomic absorption spectroscopy: kana mwaranzi inoburitswa neimwe mwenje sosi inopfuura nepamhepo yeatomu yechinhu chinoyerwa, inotorwa nemaatomu epasi, uye dhigirii rekunyudza rakayerwa rinogona kuyerwa kuti riongorore.
Atomic absorption spectrometry uye inogona kuzadzana uye haigone kutsiviwa neimwe neimwe.
3. Zvinhu zvinokanganisa kuyerwa kwetsvina
1. Mhedzisiro yevhoriyamu yekuenzanisira pamutengo webvunzo
Mukuita, zvinoonekwa kuti sampling chiyero chedhaimani poda ine simba guru pamhedzisiro yebvunzo. Kana iyo sampling yakawanda iri 0.50g, avhareji yekutsauka kwebvunzo yakakura; apo sampling chiyero chiri 1.00g, avhareji yekutsauka idiki; apo sampling chiyero chiri 2.00g, kunyangwe kutsauka kuri kudiki, nguva yekuyedza inowedzera uye kugona kunoderera. Naizvozvo, panguva yekuyerwa, nekupofumadza kuwedzera huwandu hwesampling hazvireve kuvandudza kurongeka uye kugadzikana kwemhedzisiro yekuongorora, asiwo kuchawedzera zvakanyanya nguva yekushanda uye kuderedza kushanda zvakanaka.
2. Kufurira kwechikamu chekukura pane zvisina kuchena
Kana chimedu chehupfu hwedhaimondi chakanatswa, ndiko kuwedzera kwekusachena kuri muhupfu. Avhareji saizi yechidimbu i3um muhupfu hwedhaimani mukugadzirwa, nekuda kwehukuru hwakatsetseka, imwe asidhi uye zvigadziko zvisinganyunguriki zvakasanganiswa mumidziyo hazvisi nyore kupatsanura, saka inogadzikana muhupfu hwehupfu, nekudaro ichiwedzera zviri mukati metsvina. Zvakare, iyo yakanyanya kunaka saizi yechikamu, iyo yakawanda mukugadzira maitiro, kunowedzera kusvibiswa mukati mekunze, sekuparadzira, kugadzirisa mvura, kugadzirwa kwenzvimbo yeguruva kusvibiswa kwetsvina mukudzidza kweupfu sampuro yekusachena yemukati bvunzo, takaona kuti inopfuura 95% yezvakakora-grained diamond poda zvigadzirwa, kusachena kwayo kuri pazasi pe0.50 muupfu hwepasi pehupfu hwakatsetseka pazasi pe 0.50% yehupfu hwakatsetseka. 1.00%. Naizvozvo, muhupfu hwehuhu kutonga, hupfu hwakatsetseka hunofanira kunge huri pasi pe1.00%; kusvibiswa kwemukati kwe3um kunofanira kunge kuri pasi pe0.50%; uye nzvimbo mbiri dzedesimali dzinofanirwa kuchengetwa mushure mekusachena kwemukati data muyero. Nokuti nekufambira mberi kwekugadzira teknolojia yehupfu, kusvibiswa kwehupfu muhupfu huchaderedza zvishoma nezvishoma, chikamu chikuru chekusvibiswa kwehupfu hwehupfu huri pasi pe 0.10%, kana nzvimbo imwe chete yedesimali yakachengetwa, hutano hwayo haugoni kunyatsosiyanisa.
