SI1-SI2 B Giredhi HPHT Murume Akaita Diamond Stone For Jewels
- Chii chinonzi Lab Yakakura Diamond
Misiyano pakati pechisikigo nerabhu yakura madhaimondi anobva pamagadzirirwo aakaitwa.Lab akarimwa madhaimani anogadzirwa nevanhu murabhoritari nepo madhaimondi echisikigo achigadzirwa muvhu.
Madhaimondi ekutanga akabudirira ekugadzira akagadzirwa nekutevedzera zvisikwa neHigh Pressure/High Temperature (HPHT) kugadzira.Kune matatu ekutanga maitiro ekugadzira anoshandiswa kugadzira HPHT madhaimani: iyo bhandi muchina, cubic press, uye split-sphere (BARS) press.Chinangwa chemaitiro ega ega kugadzira nharaunda ine yakanyanya kudzvanywa uye tembiricha uko kukura kwedhaimani kunogona kuitika.Imwe neimwe nzira inotanga nemhodzi diki yedhaimondi inoiswa mucarbon yoiswa pasi pekumanikidzwa kwakanyanya uye tembiricha kuti dhaimondi rikure.
Imwe nzira yakakurumbira yekukura synthetic diamnd ndeyemakemikari vapor deposition (CVD).Kukura kunoitika pasi pekumanikidzwa kwakaderera (pasi pemhepo yemhepo).Zvinosanganisira kudyisa musanganiswa wemagasi (kazhinji 1 kusvika 99 methane kune haidrojeni) muchamver uye nekuapatsanura kune makemikari anoshanda radicals muplasma inobatidzwa nemamicrowaves, inopisa filament, arcdischarge, welding torch kana laser.Iyi nzira inonyanya kushandiswa pakupfekedza, asi inogonawo kuburitsa makristasi mamwe mamirimita akawanda muhukuru.
