Idayimani eyenziwe ngumntu VS Idayimani yeNdalo
Idayimani eyenziwe ngumntu VS Idayimani yeNdalo
Iidayimani zendalo yenye yezinto ezimangalisayo zendalo. Zinokuba neebhiliyoni ezininzi zeminyaka ubudala, zenziwe ngento enye (carbon), kwaye zenziwe nzulu emhlabeni phantsi kobushushu obuphezulu kunye noxinzelelo olukhulu.
Xa kuziwa kwidayimane yendalo, sijonge into enqabileyo kunye nobutyebi obuvela eMhlabeni kwaye isetyenziswa kakhulu kwishishini lobucwebe. Kodwa iidayimani ezenziwe ngabantu zinendawo emarikeni.
Iidayimani ezenziwe ngabantu ziye ziveliswa ngeenjongo zoshishino ukususela kwiminyaka yoo-1950 kwaye zisetyenziswa kwiintlobo ngeentlobo zezicelo: unxibelelwano lomnxeba, i-laser optics, ukhathalelo lwempilo, ukusika, ukugaya kunye nokugaya, njl.
Iidayimani ezenziwe ngabantu ziveliswa ngeendlela ezimbini:
1. Uxinzelelo oluphezulu, ubushushu obuphezulu (HPHT): Idayimane eyenziwe ngumntu iveliswa kwibhubhoratri okanye kwifektri ngokulinganisa uxinzelelo oluphezulu, iimeko zobushushu obuphezulu ezenza idayimane yendalo emhlabeni.
2. I-Chemical Vapor Deposition (CVD): Idayimani eyenziwe ngumntu iveliswa kwilabhoratri kusetyenziswa igesi etyebileyo ngekhabhoni (efana nemethane) kwigumbi lokufunxa.
Umahluko phakathi kwedayimani ezenziwe ngumntu kunye nedayimane yendalo
Iidayimani zendalo zibonisa iyantlukwano kwiipropati zazo ukusuka kwidayimani ezenziwe ngumntu ngenxa yeemeko ezahlukeneyo zokukhula ezenza kuzo.
1. Imilo yeCrystal: Amaqondo obushushu okukhula kwekristale yedayimani yendalo kunye needayimani ezenziwe elabhoratri ziyafana, kodwa iidayimani zikhula njenge-octahedral (ubuso obunxantathu obulinganayo) iikristale, kunye neekristale zedayimani ezenziwe ngumntu zikhula kunye ne-octahedral kunye ne-cubic (ezintandathu zilingana. ubuso besikwere) iikristale.
2. Ukufakwa: Iidayimani zendalo kunye nezenziwe ngabantu zingabonisa ukubandakanywa okuhlukeneyo (i-fractures, ikhefu, ezinye iikristale, iibhubhu ezingenanto), ngoko azisoloko zizixhobo zokuxilonga ukuchongwa kwe-gem, uShigley uthi.
3. Ukucaca: Iidayimani ezenziwe ngabantu zinokusuka ezantsi ukuya phezulu.
4. Umbala: Iidayimani ezenziwe ngabantu zidla ngokungabi nambala, kufutshane-nemibala, ukukhanya ukuya kumthubi omnyama, okanye tyheli-mdaka; azifane zibe bhlowu, zipinki-bomvu, okanye zibe luhlaza. Iidayimani ezenziwe ngumntu zinokulawulwa kunyango olufanayo lombala njengedayimani yendalo, ngoko nawuphi na umbala unokwenzeka.
I-PDC cutter luhlobo lwemathiriyeli enzima kakhulu edibanisa i-polycrystalline diamond ene-tungsten carbide substrate. Igrit yedayimani yeyona nto iphambili ekrwada kubasiki bePDC. Ngenxa yokuba iidayimani zendalo zinzima ukwenza kwaye zithatha ixesha elide, zibiza kakhulu kwaye zibiza kakhulu kwi-industrial application, kulo mzekelo, idayimani eyenziwe ngumntu idlale indima enkulu kwishishini.
I-ZZbetter inolawulo olungqongqo kwizinto ezikrwada zegrit yedayimane. Ukwenza i-PDC cutter oilfield drilling, sisebenzisa idayimane evela kumazwe angaphandle. Kwakhona kufuneka siyiqhekeze kwaye siyibumbe kwakhona, senze ubungakanani be-particle size ifanane. Sisebenzisa iLaser Particle Size Analyzer ukuhlalutya ukuhanjiswa kobungakanani besuntswana, ubunyulu, kunye nobukhulu kwibhetshi nganye yedayimane yomgubo.
Ukuba unomdla kwi PDC cutters kwaye ufuna ulwazi oluthe vetshe kunye neenkcukacha, UNGAQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
