Chinhu chikuru chedhaimondi icarbon, inova mineral inoumbwa necarbon elements.Iyo allotrope yegraphite ine kemikari formula yeC, inovawo muviri wekutanga wemadhaimondi akajairika.Dhaimondi ndicho chinhu chakaomesesa chinoitika muzvisikwa.Dhaimondi rine mavara akasiyana-siyana, kubva asina ruvara kusvika kune dema.Inogona kuve yakajeka, inopenya kana kuti opaque.Madhaimondi mazhinji aneyero, izvo zvinonyanya kukonzerwa netsvina iri mumadhaimondi.Iyo refractive index yedhaimani yakakwira zvakanyanya, uye kuita kwekuparadzira kwakasimba zvakare, ndosaka dhaimondi richiratidza kupenya kwemavara.Dhaimondi richaburitsa bhuruu-girinhi fluorescence pasi peX-ray irradiation.
Madhaimani ndiwo matombo ekwavo, uye madhaimani kune dzimwe nzvimbo anotakurwa nenzizi nemazaya echando.Dhaimondi rinowanzoita granular.Kana dhaimondi rikapisa kusvika 1000 ° C, inoshanduka zvishoma nezvishoma kuita graphite.Muna 1977, mumwe mugari wemuChanglin, Sushan Township, Linshu County, Shandong Province, akawana dhaimondi guru reChina pasi.Madhaimondi makuru emaindasitiri epasi rose uye madhaimondi egiredhi-giredhi anogadzirwa muSouth Africa, ese anodarika zviuru zvitatu nemazana mana emakarati (1 karati = 200 mg).Iyo gem-giredhi madhaimondi ari 10 × 6.5 × 5 masendimita muhukuru uye anonzi "Cullinan".Mumakore ekuma1950, United States yakashandisa graphite sechinhu chakabikwa kuti ibudirire kugadzira madhaimani ekugadzira pasi pekupisa kwakanyanya uye kumanikidzwa.Iye zvino madhaimani ekugadzira ave kushandiswa zvakanyanya mukugadzira uye hupenyu hwezuva nezuva.
Mushonga wekemikari yedhaimondi ndeye c.iyo yekristaro fomu yedhaimani kazhinji octahedron, rhombic dodecahedron, tetrahedron uye kuunganidzwa kwavo.Kana pasina tsvina, haina ruvara uye yakajeka.Kana ichiita neokisijeni, inoburitsawo kabhoni dhayokisaidhi, inova yeiyo imwechete elemental kabhoni segraphite.Iyo bond angle ye diamond crystal ndeye 109 ° 28 ', iyo ine yakanakisa zvimiro zvemuviri senge superhard, kusapfeka-resistant, thermal senitivity, thermal conductivity, semiconductor uye kure transmission.Iyo inozivikanwa se "mambo wekuoma" uye mambo wematombo anokosha.Iyo kona yekristaro yedhaimani ndeye 54 madhigirii 44 maminetsi 8 masekonzi.Pachivanhu, vanhu vanowanzodaidza dhaimondi rakagadziriswa uye dhaimondi risina kugadziriswa.MuChina, zita redhaimani rakatanga kuwanikwa mumagwaro echiBuddha.Dhaimondi ndicho chinhu chakaomesesa muzvisikwa.Rudzi rwakanakisisa haruna ruvara, asi kunewo mavara anokosha, akadai sebhuruu, ruvara rwepepuru, ndarama yero, etc. Aya madhaimondi ane mavara haawanzo uye pfuma mumadhaimondi.India ndiyo nyika ine mukurumbira mukugadzira madhaimani munhoroondo.Iye zvino madhaimani akawanda ane mukurumbira munyika, akadai se "gomo rechiedza", "Regent" uye "Orlov", anobva kuIndia.Kugadzirwa kwedhaimani kushoma zvikuru.Kazhinji, dhaimondi rakapedzwa bhiriyoni imwe yehuwandu hwemigodhi, saka mutengo unodhura zvakanyanya.Mushure mekucheka, madhaimondi anowanzo kutenderera, rectangular, square, oval, moyo-kuumbwa, pear shaped, olive pointed, etc. Dhaimondi rinorema kudarika mamwe ose pasi rose i "curinan" rakagadzirwa muSouth Africa muna 1905. Inorema 3106.3 carats uye yave yakagadzirwa akagayiwa kuita 9 madhaimani madiki.Mumwe wavo, curinan 1, anozivikanwa se "African star", achiri nhanho yekutanga munyika.
Madhaimani ane zvakasiyana-siyana zvekushandisa.Zvinoenderana nekushandiswa kwavo, madhaimani anogona kukamurwa kuita zvikamu zviviri: gem-giredhi (kushongedza) madhaimondi uye maindasitiri-giredhi madhaimondi.
Gem giredhi madhaimani anonyanya kushandiswa zvishongo zvakaita semhete dzedhaimondi, mhete, mhete, corsages, uye zvinhu zvakakosha zvakaita sekorona netsvimbo, pamwe nekuunganidzwa kwematombo akaomarara.Zvinoenderana nenhamba, kutengeserana kwemadhaimani kunoda kusvika makumi masere muzana ezvese zvegore rose zvekutengesa zvishongo pasi rose.
Madhaimani egiredhi-giredhi ari kuramba achishandiswa zvakanyanya, aine kuomarara kwakanyanya uye nekupfeka kwakanaka kuramba, uye anogona kushandiswa zvakanyanya mukucheka, kukuya, nekuchera;diamond poda inoshandiswa seyepamusoro-giredhi abrasive zvinhu.
Semuyenzaniso:
1. Gadzira resin bond abrasive maturusi kanamidziyo yekukuya, nezvimwewo.
2. KugadziraMetal Diamond Kukuya Zvishandiso, ceramic bond abrasive maturusi kana maturusi ekukuya, nezvimwe.
3. Kugadzira general stratum geological drilling bits, semiconductor uye isiri-metallic zvinhu zvekucheka maturusi ekugadzira, nezvimwe.
4. Kugadzira hard-stratum geological drill bits, maturusi ekugadzirisa uye asina-metallic yakaoma uye brittle zvinhu zvekugadzirisa zvishandiso, nezvimwewo.
5. Resin diamond polishing pads, ceramic bond abrasive maturusi kana kugaya, nezvimwe.
6. Metal bond abrasive tools uye electroplated products.Zvishandiso zvekuchera kana kukuya, nezvimwe.
7. Kucheka, kuchera uye kugadzirisa maturusi, nezvimwewo.
Pamusoro pezvo, yakashandiswawo zvakanyanya muindasitiri yemauto uye tekinoroji yemuchadenga.
Nekukurumidza kukura kwesainzi uye tekinoroji uye indasitiri yemazuva ano, kushandiswa kwedhaimondi kuchawedzera nekufara, uye huwandu huchawedzera.Natural diamond zviwanikwa zvishoma.Kusimbisa kugadzirwa uye kutsvagisa kwesainzi kwedhaimani rekugadzira richava chinangwa chenyika dzese pasirese.Poshi.
