Idayimane elenziwe umuntu VS Idayimane Lemvelo
Idayimane elenziwe umuntu VS Idayimane Lemvelo
Amadayimane emvelo angenye yezimangaliso zemvelo. Zingaba izigidigidi zeminyaka ubudala, zenziwe nge-elementi eyodwa (carbon), futhi zakheka ekujuleni komhlaba ngaphansi kwezinga lokushisa eliphezulu nokucindezela okukhulu.
Uma kukhulunywa ngedayimane lemvelo, sibheka into eyivelakancane nengcebo evela eMhlabeni futhi isetshenziswa kakhulu embonini yobucwebe. Kodwa amadayimane enziwe abantu anendawo emakethe.
Amadayimane enziwe umuntu akhiqizwe izinjongo zezimboni kusukela ngeminyaka yawo-1950s futhi asetshenziswa ezinhlobonhlobo zezicelo: ezokuxhumana, i-laser optics, ukunakekelwa kwezempilo, ukusika, ukugaya nokubhola, njll.
Amadayimane enziwe abantu akhiqizwa ngezindlela ezimbili:
1. High Pressure, High Temperature (HPHT): Idayimane elenziwe ngumuntu likhiqizwa elabhorethri noma efekthri ngokulingisa umfutho ophezulu, izimo zokushisa eziphezulu ezakha idayimane lemvelo eMhlabeni.
2. I-Chemical Vapor Deposition (CVD): Idayimane elenziwe ngumuntu likhiqizwa elabhorethri kusetshenziswa igesi enothile ngekhabhoni (njenge-methane) egumbini lokuhlanza.
Umehluko phakathi kwamadayimane enziwe umuntu nedayimane lemvelo
Amadayimane emvelo abonisa umehluko ezimpahleni zawo kusukela kumadayimane enziwe umuntu ngenxa yezimo ezihlukene zokukhula akha kuzo.
1. I-Crystal Shape: Amazinga okushisa okukhula kwekristalu ledayimane lemvelo kanye namadayimane enziwe elabhorethri ayafana, kodwa amadayimane akhula njengamakristalu e-octahedral (ubuso obunxantathu obulinganayo obuyisishiyagalombili), futhi amakristalu edayimane enziwe umuntu akhula nakho kokubili i-octahedral kanye ne-cubic (okulinganayo okuyisithupha ubuso besikwele) amakristalu.
2. Okufakiwe: Amadayimane emvelo nawenziwe umuntu angabonisa okufakiwe okuhlukahlukene (ama-fractures, ama-breaks, amanye amakristalu, amashubhu angenalutho), ngakho-ke awawona njalo amathuluzi okuxilonga ukuhlonza amagugu, kusho u-Shigley.
3. Ukucaca: Amadayimane enziwe umuntu angaba ukusuka kokuncane ukuya kokucaca okuphezulu.
4. Umbala: Amadayimane enziwe umuntu ngokuvamile awanambala, acishe abe nemibala, akhanyayo kuye kophuzi okumnyama, noma ansundu ngokuphuzi; awavamile ukuba luhlaza okwesibhakabhaka, abomvu-obomvu, noma aluhlaza. Amadayimane enziwe umuntu angaphathwa ngendlela efanayo ngombala njengedayimane lemvelo, ngakho noma yimuphi umbala ungenzeka.
I-PDC cutter iwuhlobo lwezinto eziqinile kakhulu ezihlanganisa idayimane le-polycrystalline nge-tungsten carbide substrate. Igridi yedayimane iyisisetshenziswa esibalulekile sabasiki be-PDC. Ngenxa yokuthi amadayimane emvelo anzima ukwakha futhi athatha isikhathi eside, ayabiza kakhulu futhi abiza kakhulu ekusetshenzisweni kwezimboni, kulokhu, idayimane eyenziwe ngumuntu ibambe iqhaza elikhulu embonini.
I-ZZbetter inokulawula okuqinile phezu kwezinto ezingavuthiwe zegrit yedayimane. Ukwenza i-PDC cutter oilfield drilling, sisebenzisa idayimane elingenisiwe. Kufanele futhi siyichoboze futhi siyilolonge futhi, senze usayizi wezinhlayiyana ube umfaniswano. Sisebenzisa i-Laser Particle Size Analyzer ukuze sihlaziye ukusabalalisa usayizi wezinhlayiyana, ubumsulwa, kanye nosayizi weqoqo ngalinye lempushana yedayimane.
Uma unentshisekelo kubasiki be-PDC futhi ufuna ulwazi olwengeziwe kanye nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE I-IMEYILI ezansi nekhasi.
