Taemane e entsoeng ke motho VS Taemane ea Tlhaho

Litaemane tsa tlhaho ke tse ling tsa limakatso tsa tlhaho. Li ka ba lilemo tse libilione tse ’maloa, li entsoe ka elemente e le ’ngoe (carbon), ’me li thehoa botebong ba lefatše tlas’a mocheso o phahameng le khatello e feteletseng.

Ha ho tluoa tabeng ea daemane ea tlhaho, re shebile ntho e sa tloaelehang le letlotlo le tsoang Lefatšeng 'me e sebelisoa haholo indastering ea mabenyane. Empa litaemane tse entsoeng ke batho li na le sebaka ’marakeng.

Litaemane tse entsoeng ke batho li 'nile tsa hlahisoa molemong oa indasteri ho tloha lilemong tsa bo-1950' me li sebelisoa mefuteng e mengata e fapaneng ea lisebelisoa: lithelefono, laser optics, tlhokomelo ea bophelo bo botle, ho itšeha, ho sila le ho cheka, joalo-joalo.

Litaemane tse entsoeng ke batho li hlahisoa ka litsela tse peli:

1. High Pressure, High Temperature (HPHT): Taemane e entsoeng ke motho e hlahisoa laboratoring kapa fekthering ka ho etsisa khatello e phahameng, maemo a mocheso a phahameng a etsang litaemane tsa tlhaho Lefatšeng.

2. Chemical Vapor Deposition (CVD): Taemane e entsoeng ke motho e hlahisoa laboratoring e sebelisang khase e nang le carbon e ngata (e kang methane) ka kamoreng ea vacuum.

Phapang pakeng tsa litaemane tse entsoeng ke motho le taemane ea tlhaho

Litaemane tsa tlhaho li bontša phapang ea thepa ea tsona ho tloha ho litaemane tse entsoeng ke batho ka lebaka la maemo a fapaneng a kholo ao li hlahang ho tsona.

1. Crystal Shape: Thempereichara bakeng sa khōlo ea kristale ea taemane ea tlhaho le ea litaemane tse entsoeng ka laboratoring ea tšoana, empa litaemane li hola joalo ka likristale tsa octahedral (lifahleho tse robeli tse equilateral triangular), 'me likristale tsa taemane tse entsoeng ke motho li hola ka bobeli octahedral le cubic (tse lekanang tse tšeletseng. square faces) likristale.

2. Li-inclusions: Litaemane tsa tlhaho le tse entsoeng ke batho li ka bonts'a li-inclusions tse fapa-fapaneng (li-fractures, likheo, likristale tse ling, li-tubes tse sekoti), kahoo ha se kamehla lisebelisoa tsa ho hlahloba bakeng sa boitsebiso ba majoe, Shigley o re.

3. Ho hlaka: Litaemane tse entsoeng ke motho li ka ba tse hlakileng ho tloha ho tse tlaase ho isa ho tse hlakileng.

4. Mmala: Litaemane tse entsoeng ke batho hangata ha li na ’mala, ha li na ’mala, li khanya ho isa ho bosehla bo lefifi, kapa bosootho bo mosehla; hangata ha li boputsoa, ​​bo pinki-khubelu, kapa botala. Litaemane tse entsoeng ke batho li ka phekoloa ka mebala e tšoanang le ea litaemane tsa tlhaho, kahoo mebala leha e le efe e ka khoneha.

PDC cutter ke mofuta oa thepa e thata haholo e kopanyang daemane ea polycrystalline e nang le tungsten carbide substrate. Diamond grit ke sesebelisoa sa bohlokoa bakeng sa li-cutters tsa PDC. Hobane litaemane tsa tlhaho li thata ho theha 'me li nka nako e telele, li theko e boima haholo ebile li theko e boima bakeng sa tšebeliso ea indasteri, tabeng ena, taemane e entsoeng ke motho e phethile karolo e kholo indastering.

ZZbetter e na le taolo e tiileng holim'a lisebelisoa tse tala tsa grit ea daemane. Bakeng sa ho cheka sebaka sa oli sa PDC cutter, re sebelisa daemane e tsoang kantle ho naha. Re boetse re tlameha ho e pshatla le ho e bōpa hape, ho etsa hore boholo ba likaroloana bo tšoane. Re sebelisa Laser Particle Size Analyzer ho sekaseka kabo ea boholo ba likaroloana, bohloeki le boholo ba beche ka 'ngoe ea phofo ea daemane.

Haeba o khahlehela li-cutters tsa PDC 'me u batla lintlha le lintlha tse ling, u ka ITHUTA KA HO THUSA KA mohala kapa ka poso ka letsohong le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.
