Daimondi Yopangidwa ndi Munthu VS Diamondi Yachilengedwe

Ma diamondi achilengedwe ndi chimodzi mwa zodabwitsa za chilengedwe. Zitha kukhala zaka mabiliyoni angapo, zopangidwa ndi chinthu chimodzi (carbon), ndipo zimapangidwira pansi pa nthaka pansi pa kutentha kwakukulu ndi kupanikizika kwambiri.

Pankhani ya diamondi yachilengedwe, tikuyang'ana chinthu chomwe chili chosowa komanso chuma chochokera kudziko lapansi ndipo chimagwiritsidwa ntchito makamaka m'makampani opanga zodzikongoletsera. Koma diamondi zopangidwa ndi anthu zili ndi malo pamsika.

Ma diamondi opangidwa ndi anthu amapangidwa chifukwa cha mafakitale kuyambira zaka za m'ma 1950 ndipo amagwiritsidwa ntchito pazinthu zosiyanasiyana: mauthenga a telefoni, laser optics, chisamaliro chaumoyo, kudula, kugaya ndi kubowola, etc.

Ma diamondi opangidwa ndi anthu amapangidwa m'njira ziwiri:

1. Kuthamanga Kwambiri, Kutentha Kwambiri (HPHT): Daimondi yopangidwa ndi anthu imapangidwa mu labotale kapena fakitale potengera kupanikizika kwapamwamba, kutentha kwambiri komwe kumapanga diamondi zachilengedwe padziko lapansi.

2. Chemical Vapor Deposition (CVD): Daimondi yopangidwa ndi anthu imapangidwa mu labotale pogwiritsa ntchito mpweya wochuluka wa carbon (monga methane) mu chipinda chounikira.

Kusiyana pakati pa diamondi zopangidwa ndi anthu ndi diamondi yachilengedwe

Ma diamondi achilengedwe amawonetsa kusiyana kwa zinthu zawo kuchokera ku diamondi zopangidwa ndi anthu chifukwa cha kukula kwake komwe amapangidwira.

1. Mawonekedwe a Crystal: Kutentha kwa kristalo wachilengedwe wa diamondi ndi diamondi yopangidwa mu labotale ndi yofanana, koma diamondi imakula ngati makristalo a octahedral (eight equilateral triangular faces), ndipo miyala ya diamondi yopangidwa ndi anthu imakula ndi octahedral ndi cubic (zofanana zisanu ndi chimodzi). square faces) makhiristo.

2. Kuphatikizika: Ma diamondi achilengedwe ndi opangidwa ndi anthu amatha kuwonetsa zophatikizika zosiyanasiyana (zophulika, zopumira, makristasi ena, machubu opanda pake), kotero sizikhala zida zowunikira nthawi zonse zozindikiritsa miyala yamtengo wapatali, Shigley akuti.

3. Kumveka momveka bwino: Ma diamondi opangidwa ndi anthu amatha kukhala otsika kwambiri mpaka omveka bwino.

4. Utoto: Ma diamondi opangidwa ndi anthu kaŵirikaŵiri amakhala opanda mtundu, pafupifupi opanda mtundu, owala mpaka achikasu chakuda, kapena achikasu-bulauni; nthawi zambiri amakhala abuluu, ofiira apinki, kapena obiriwira. Ma diamondi opangidwa ndi anthu amatha kuthandizidwa ndi mitundu yofanana ndi diamondi yachilengedwe, kotero kuti mtundu uliwonse utheka.

PDC cutter ndi mtundu wazinthu zolimba kwambiri zomwe zimagwirizanitsa diamondi ya polycrystalline ndi tungsten carbide gawo lapansi. Grit ya diamondi ndiye chinthu chofunikira kwambiri kwa ocheka a PDC. Chifukwa diamondi zachilengedwe zimakhala zovuta kupanga ndipo zimatenga nthawi yayitali, zimakhala zokwera mtengo komanso zotsika mtengo pakugwiritsa ntchito mafakitale, pamenepa, diamondi yopangidwa ndi anthu yakhala ndi gawo lalikulu pamakampani.

ZZbetter ili ndi mphamvu zowongolera zopangira zida za diamondi. Popanga pobowola PDC cutter oilfield, timagwiritsa ntchito diamondi yotumizidwa kunja. Tiyeneranso kuphwanya ndi kuumba kachiwiri, kupanga tinthu kukula yunifolomu. Timagwiritsa ntchito Laser Particle Size Analyzer kusanthula kukula kwa tinthu, chiyero, ndi kukula kwa gulu lililonse la ufa wa diamondi.

Ngati mukufuna zodula za PDC ndipo mukufuna zambiri ndi zambiri, mutha KULAMBIRA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZENI MAIL pansi pa tsambali.
