Madhaimondi akagadzirwa nemunhu VS Natural Diamond

Madhaimani echisikigo ndechimwe chezvishamiso zvechisikigo. Inogona kuva nemabhiriyoni emakore ekare, yakagadzirwa nechinhu chimwe chete (carbon), uye inoumbwa pasi pasi pasi pekushisa kwepamusoro uye kudzvinyirira kwakanyanya.

Kana zvasvika kune dhaimondi rechisikigo, isu tiri kutarisa chimwe chinhu chisingawanike uye pfuma kubva kuPasi uye inonyanya kushandiswa muindasitiri yezvishongo. Asi madhaimondi anogadzirwa nevanhu ane nzvimbo pamusika.

Madhaimondi akagadzirwa nevanhu akagadzirwa nekuda kwemaindasitiri kubva kuma1950s uye anoshandiswa mumhando dzakasiyana siyana dzekushandisa: telecommunication, laser optics, hutano hwehutano, kucheka, kukuya nekuchera, nezvimwe.

Madhaimondi anogadzirwa nevanhu anogadzirwa nenzira mbiri:

1. High Pressure, High Temperature (HPHT): Dhaimondi rinogadzirwa nevanhu rinogadzirwa murabhoritari kana fekitori nekutevedzera kudzvanywa kwepamusoro, kutonhora kwakanyanya kunoumba madhaimondi echisikigo paNyika.

2. Chemical Vapor Deposition (CVD): Dhaimondi yakagadzirwa nemunhu inogadzirwa mu laboratori inoshandisa carbon-rich gas (yakadai semethane) muimba yekutsvaira.

Musiyano uripo pakati pemadhaimondi akagadzirwa nevanhu nedhaimondi rechisikigo

Madhaimondi echisikigo anoratidza misiyano yezvivakwa zvawo kubva kumadhaimondi akagadzirwa nevanhu nekuda kwekusiyana kwekukura kwaanoumba.

1. Crystal Shape: Tembiricha yekukura kwekristaro yedhaimani yakasikwa uye yemadhaimani anogadzirwa murabhoritari yakafanana, asi madhaimani anokura semaoctahedral (eight equilateral triangular faces) makristasi, uye makristasi edhaimani anogadzirwa nevanhu anokura aine ose octahedral uye cubic (matanhatu akaenzana. square faces) makristasi.

2. Inclusions: Madhaimondi echisikigo uye akaitwa nevanhu anogona kuratidza zvakasiyana-siyana (fractures, breaks, mamwe makristasi, hollow tubes), saka haisi nguva dzose maturusi ekuongorora kuti gem identification, Shigley anoti.

3. Kujeka: Madhaimani anogadzirwa nevanhu anogona kubva pasi kusvika pakujeka.

4. Ruvara: Madhaimani anogadzirwa nevanhu kazhinji haana ruvara, ari pedyo-asina ruvara, akajeka kusvika kune yakasviba yero, kana yero-brown; havanyanyi kuwanzoita bhuruu, pink-tsvuku, kana girini. Madhaimondi akagadzirwa nevanhu anogona kuitiswa kurapwa kwemavara akafanana nemadhaimani echisikigo, saka chero ruvara rwunogoneka.

PDC cutter imhando yemhando dzakaoma-zvakaoma izvo zvinobatanidza polycrystalline diamond ine tungsten carbide substrate. Dhaimondi grit ndiyo yakakosha zvinhu zvePDC vanocheka. Nekuti madhaimondi echisikigo akaoma kuumba uye anotora nguva yakareba, anodhura zvakanyanya uye anodhura pakushandiswa kwemaindasitiri, mune iyi nyaya, dhaimondi rakagadzirwa nevanhu rakaita basa guru muindasitiri iyi.

ZZbetter ine kudzora kwakasimba pamusoro pezvakagadzirwa zvedhaimani grit. Pakugadzira iyo PDC cutter oilfield yekuchera, isu tinoshandisa dhaimondi rinotengeswa kunze kwenyika. Isu tinofanirawo kuipwanya uye kuigadzira zvakare, zvichiita kuti saizi yepakati iwedzere kufanana. Isu tinoshandisa Laser Particle Size Analyzer kuongorora iyo particle saizi kugovera, kuchena, uye saizi yebhechi yega yega yedhaimani poda.

Kana iwe uchifarira PDC cutters uye uchida rumwe ruzivo uye ruzivo, unogona KUTITA NEI runhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi pepeji.
