Pob zeb diamond VS ntuj pob zeb

Ntuj pob zeb diamond yog ib qho ntawm cov xwm txheej xav tau. Lawv tuaj yeem ua tau ntau txhiab xyoo, ua los ntawm ib lub ntsiab lus (carbon), thiab tsim sib sib zog nqus hauv lub ntiaj teb nyob rau hauv qhov kub thiab txias.

Thaum nws los txog rau lub ntuj pob zeb diamond, peb tab tom saib ib yam dab tsi uas tsis tshua muaj thiab cov khoom muaj nqis los ntawm lub ntiaj teb thiab feem ntau yog siv hauv kev lag luam hniav nyiaj hniav kub. Tab sis tib neeg tsim pob zeb diamond muaj qhov chaw hauv khw.

Cov pob zeb tsim los ntawm tib neeg tau tsim rau kev lag luam txij li xyoo 1950s thiab tau siv ntau yam kev siv: kev sib txuas lus, laser optics, kev kho mob, txiav, sib tsoo thiab drilling, thiab lwm yam.

Cov neeg tsim pob zeb diamond yog tsim nyob rau hauv ob txoj kev:

1. Kev kub siab, kub kub (HPHT): Ib lub pob zeb diamond uas neeg tsim tau tsim nyob rau hauv chav kuaj lossis lub Hoobkas los ntawm kev ua raws li cov kev kub ntxhov siab, kub kub uas tsim cov pob zeb diamond hauv lub ntiaj teb.

2. Chemical Vapor Deposition (CVD): Lub pob zeb diamond uas neeg tsim tau tsim nyob rau hauv chav kuaj siv cov pa roj carbon nplua nuj (xws li methane) hauv lub tshuab nqus tsev.

Qhov sib txawv ntawm cov neeg tsim pob zeb diamond thiab ntuj pob zeb diamond

Ntuj pob zeb diamonds qhia qhov sib txawv ntawm lawv cov khoom los ntawm cov neeg tsim cov pob zeb diamond vim qhov sib txawv ntawm kev loj hlob nyob rau hauv uas lawv tsim.

1. Crystal Shape: Qhov kub thiab txias rau lub ntuj pob zeb diamond siv lead ua kev loj hlob thiab rau cov pob zeb diamond ua nyob rau hauv lub chaw kuaj mob zoo sib xws, tab sis pob zeb diamonds loj hlob li octahedral (yim equilateral daim duab peb sab ntsej muag) muaju, thiab cov txiv neej ua pob zeb diamond muaju loj hlob nrog ob qho tib si octahedral thiab cubic (rau qhov sib npaug. square ntsej muag) crystals.

2. Inclusions: Ntuj thiab tib neeg tsim cov pob zeb diamond tuaj yeem nthuav tawm ntau yam kev suav nrog (pob txha, tawg, lwm yam muaju, cov raj hollow), yog li lawv tsis yog ib txwm kuaj cov cuab yeej rau kev txheeb xyuas lub pov haum, Shigley hais.

3. Clarity: Man-made pob zeb diamond tuaj yeem ua los ntawm qhov qis mus rau siab clarity.

4. Xim: Cov pob zeb tsim los ntawm tib neeg feem ntau tsis muaj xim, tsis muaj xim, lub teeb rau xim daj, lossis daj-xim av; lawv tsis tshua muaj xiav, liab-liab, lossis ntsuab. Cov pob zeb tsim los ntawm tib neeg tuaj yeem raug rau tib xim kho raws li ntuj pob zeb, yog li txhua yam xim tuaj yeem ua tau.

PDC cutter yog ib yam ntawm cov khoom siv tawv tawv uas compacts polycrystalline pob zeb diamond nrog tungsten carbide substrate. Pob zeb diamond grit yog cov khoom siv tseem ceeb rau PDC cutters. Vim hais tias ntuj pob zeb diamonds nyuaj rau tsim thiab siv sij hawm ntev, lawv kim heev thiab kim heev rau kev lag luam daim ntawv thov, nyob rau hauv cov ntaub ntawv no, txiv neej-ua pob zeb diamond tau ua lub luag hauj lwm zoo nyob rau hauv kev lag luam.

ZZbetter muaj kev tswj hwm nruj ntawm cov khoom siv ntawm pob zeb diamond grit. Rau kev ua PDC cutter oilfield drilling, peb siv cov pob zeb diamond txawv teb chaws. Peb kuj yuav tsum tau zuaj thiab ua kom zoo dua, ua rau cov khoom me me zoo ib yam. Peb siv Laser Particle Size Analyzer los txheeb xyuas qhov loj me me, purity, thiab loj rau txhua pawg pob zeb diamond hmoov.

Yog tias koj txaus siab rau PDC cutters thiab xav tau cov ntaub ntawv thiab cov ntsiab lus ntxiv, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL rau hauv qab ntawm nplooj ntawv.
