Diamonds dag: lub npe ntawm tus ntau lawm

Diamonds attracted noob neej txij ancient sij hawm. Lub extraordinary kev zoo nkauj ntawm cov pob zeb tau tshwm sim los lawv siv los tsim txawv kho kom zoo nkauj. Txawm li cas los, tom qab ntawd, cov neeg pom lwm yam tseem ceeb thaj chaw ntawm cov pob zeb diamond - lawv cov cim zog thiab hardness. Yuav ua kom cov kev xav tau ntawm ntau lawm rau qhov tsis tau tsim ib tug ntau ntawm cov khoom no, kom cov neeg muaj ib lub tswv yim - los tsim diamonds artificially.

pob zeb diamond nqi

Pob zeb diamond yog suav tias yog ib tug tshwj xeeb cov pob zeb, muaj ib tug tsawg ua ke ntawm ib qho tseem ceeb cov yam ntxwv: muaj zog dispersion, siab thermal conductivity, hardness, kho qhov muag clarity, durability. Vim nws lub cev thiab txhua yam khoom ntawm pob zeb diamond yog co menyuam tsis tau tsuas yog hniav nyiaj hniav kub kws txawj, tab sis kuj tau lug siv nyob rau hauv ntau yam industries. Yog li ntawd, qhov no zoo zoo nkauj tshooj zeb siv nyob rau hauv cov tshuaj, optics thiab microelectronics.

Tab sis rau tag nrho raws li cov kev ntau lawm yuav tsum tau huv si tej yam ntuj tso diamonds yog heev yooj yim thiab kim heev. Vim li no, tib neeg pib xav txog yuav ua li cas ua ib co pob zeb diamond. Khoom cua pob zeb yuav tsum tsis txhob tsuas muaj qhov tseem ceeb thaj chaw ntawm cov pob zeb diamond, tab sis kuj muaj ib tug ntau zoo meej siv lead ua qauv, uas yog tseem ceeb heev rau cov technology chaw.

Zoo li tej hluavtaws diamonds

Qhov yuav tsum tau tsim ib tug hluavtaws pob zeb cia li sawv ib tug ntev heev lub sij hawm. Tab sis nyob rau hauv kev xyaum, nws nqa tawm tsuas nyob rau hauv lub XX caug xyoo. Kom txog thaum uas lub sij hawm, zaum yuav tsis tuaj nrog cov siv thiab ua cov pob zeb diamond technology, thaum muaj tsim kom muaj hais tias lawv yog cov txheeb ze nrog zoo tib yam carbon. Thiab nyob rau hauv ib tug ob peb xyoo lawm cov thawj hluavtaws pob zeb diamond, uas yog derived ntawm graphite nyob rau hauv high school kub thiab siab los ntawm ib tug theem ntawm txoj kev hloov yog tsim los pab. Los ntawm lub sij hawm ntawd pib zus tau tej cov dag diamonds, uas yog tam sim no siv nyob rau hauv ntau yam khoom ntawm cov khoom thiab seev.

pob zeb diamond lawm technology

Nyob rau hauv peb lub sij hawm, los ua hluavtaws pob zeb siv ob peb technologies, txhua tus uas muaj nws tus kheej cov yam ntxwv. Qhov tseem txhim khu kev qha, tiam sis feem ntau kim technology yog tus zus tau tej cov pob zeb diamond crystalline carbon uas yog positioned rau ua nyob rau hauv ib tug tshwj xeeb xovxwm. Ua ntej, nyob rau hauv cov ntaub ntawv uas yuav tsum tau kho yog pumped haib dej. Qhov no tsim ib tug kub siab. Ces, dej freezes nyob rau hauv tus ntawm refrigerant, uas lub siab yog nce mus rau 10 lub sij hawm. Thaum kawg theem chamber nyob rau hauv uas cov pa roj carbon yog kev cob cog rua rau lub tsheb thauj mus tuav thiab nkag rau ib tug ob peb zauv feem ntawm ib tug thib ob muaj zog tam sim no. Nyob rau hauv simultaneous kev txiav txim ntawm kub thiab siab, tus hloov dua siab tshiab ntawm graphite nyob rau hauv cov khoom pob zeb. Tom qab no theem, cov xovxwm no yaj, drained dej thiab npaj txhij yuav tawm lub dag pob zeb diamond.

Loj hlob pob zeb diamond methane

Tseem siv ib tug yooj yim hluavtaws pob zeb ntau lawm technology - moj tej tawg txoj kev, uas tso cai rau koj mus ua ib tug dag siv lead ua nyob rau hauv tus ntawm methane. Heev feem ntau, zus tau tej cov hluavtaws diamonds yog rau ob technologies. Qhov tseeb yog tias nyob rau hauv thawj cov ntaub ntawv nws yog ua tau kom tau lub siab tshaj plaws feem pua tawm ntawm diamonds, tab sis lawv yog heev me me. Qhov thib ob technology enables mus considerably kom lub resulting hluavtaws pob zeb siv methane tshuab nyob rau hauv tus ntawm kub ntawm txog 1100 ° C. moj tej tawg txoj kev ua rau nws ua tau rau tsim ib tug dag pob zeb diamond ntawm kev loj.

Hom ntawm cov khoom cua pob zeb diamond

Nyob rau hauv peb lub sij hawm, tsim ntau hom ntawm cov khoom cua pob zeb diamond: nyhav zirconia, moissanite muaju, ferroelectric, rutile, zajlus, cerussite. Lub zoo meej tshaj plaws fake pob zeb diamond yog xav tau nyhav zirconia los yog zirconium lub voos xwmfab. Nws yog ib tug zirconia. Yog li ntawd, muaj ntau yam tau hnov, raws li hu ua dag pob zeb diamond zircon. Txawm tias nws twb tsis muaj kev sib raug zoo mus rau lub ntuj pob zeb kim.

Fianit yus siab hardness, ib tug high degree ntawm dispersion thiab refractive index. Vim nws cov khoom no pob zeb txig simulates ib tug tiag tiag pob zeb diamond thiab yog dav siv nyob rau hauv lub hniav nyiaj hniav kub kev lag luam. Txawm cov kws txawj suab liab qab qhov muag yuav tsis paub qhov txawv ib tug fake los ntawm tus thawj, vim hais tias lawv ua si rau tib txoj kev.

Qhov siab tshaj plaws zoo pob zeb diamond yog xav tau ib tug analogue ntawm moissanite. Nws muaj tib lub cev zog li cov neeg ntuj pob zeb, thiab nyob rau tus kho qhov muag tsis nws txawm zoo. Nws tsuas drawback - nws yog ob nyob rau hauv hardness.

Tshwj xeeb yog nrov muaju ua los ntawm cov hlau lead iav, muaj lead oxide. Vim nws muaj pes tsawg leeg lub pob zeb amazing ua si rau lub teeb thiab brilliance yog zoo tib yam rau lub brilliance ntawm diamonds.

Qhov twg siv hluavtaws diamonds

Dag pob zeb diamond hniav nyiaj hniav kub Hoobkas yog siv lug rau zus tau tej cov khoom kim heev jewellery uas yuav tsis tau tsuas yog yuav saib zoo nkauj, tab sis kuj pheej yig heev. Cov khoom siv nrog fake pob zeb tsis zoo zuj zus thiab zoo lov.

Tsis tas li ntawd loj hlob hluavtaws pob zeb diamond yog ib feem ntawm niaj hnub kev lag luam. Raws li lawv yog ua heavy-duty cov cuab yeej: sib tsoo log, cov pob zeb diamond pom hniav, polishing log, Chisels, hnyiab, scalpels, riam, ntau yam cutters thiab ciaj tais. Khoom ua los ntawm cov pob zeb diamond khoom ua nws tau mus ua lub muaj zog alloys thiab cov ntaub ntawv. Nyob rau hauv tas li ntawd, cov pob zeb diamond muab nyiaj pab ntau tshaj cov neeg nyob rau hauv cov cav tov thiab pab kiag li lawm.

Yuav ua li cas los tsim ib qho dag pob zeb diamond nyob rau hauv tsev

Ib cov kws txawj hais lus cam uas loj hlob ib tug hluavtaws pob zeb diamond yog tau nyob rau hauv tsev. Tab sis tus neeg zus tau tej cov dag diamonds yuav tsum tau ib tug ntau lub sij hawm thiab kev rau siab.
