Ob qho kev ntsuas kub tshaj plaws
Txhawm rau txiav txim siab kub nrog kev ntseeg siab, ob txoj kev sawv ntsug txhua lwm tus. Ib qho yog lub ntsiab lus tseeb, thiab lwm yam yog cov kev xaiv niaj hnub rau kev nrawm thiab kev nyab xeeb.
1. X -}} Tshav pu fluorescence (XRF)
IbXRF kub testerYog qhov siab - Tech kub kuaj tshuab uas muab kev soj ntsuam nrawm thiab meej pem yam tsis muaj kev ua kom cov khoom puas tsuaj. Cov cuab yeej ncaj qha x-} rays ntawm cov khoom saum npoo. Cov x -}}}}} ags nyob rau hauv cov hlau kom emitary (lossis fluorescent) x - rays ntawm lub zog qib tshwj xeeb rau txhua qhov. Tus ntes tau nyeem lub zog hluav taws xob no los txiav txim siab qhov theem qis, suav nrog kub, platinum, tooj liab, thiab lwm yam.
Raug:Niaj hnub Xrf Ancalalzers yog qhov muaj tseeb heev, feem ntau tsis pub dhau 0.1% ntawm cov hluav taws kub ua tau zoo thiab feem pua txhim khu kev qha thiab feem pua
Zoo tshaj plaws rau:Cov khw muag khoom kub, pawn khw, siab {{0} Cov neeg muag khoom siv nrawm, thiab tsis yog- Kev sim kub rhuav tshem kub.
2. Cov Hluav Taws Kub Assis
Hluav taws kub assay yog ib feem pua - ome kev ntsuas lub cev ua kom lub cev sib cais los ntawm lwm cov khoom siv hauv ib qho qauv. Cov qauv tau melted hauv lub cub tawg hauv qhov cub, thiab cov cuab yeej ua hauv paus yog oxidized thiab nqus mus rau hauv ib tug ntoo khaub zig, tawm xwb muaj cov hlau sib luag. Cov hlau no tseem kho tau cais cov kub, uas yog qhov hnyav los txiav txim siab nws cov kev coj dawb huv.
Raug:Qhov no yog qhov tsis muaj txiaj ntsig rau kev sim kub, raug rau hauv1 ntu hauv 10,000Cov. Nws yog tus qauv siv rau cov ntawv pov thawj raug cai thiab los ntawm cov mastic.
Zoo tshaj plaws rau:Refiners, mining kev ua haujlwm, thiab official bullion pov thawj qhov kev ua tau zoo tshaj plaws uas yuav tsum tau ua thiab cov qauv tuaj yeem raug rhuav tshem. Nws tsis haum rau tag cov hniav nyiaj hniav kub, npib, lossis cov kab uas yuav tsum tau tshwj tseg.
Kev sib piv ntawm cov kev ntsuas kub
Cov lus no muab cov ntsiab lus ceev ntawm cov txheej txheem feem ntau siv los sim cov kev ua siab loj, pab koj pom cov lag luam {{{0} {{0} {{0} {{0} {{0} {} {{0} {{{0} {{0} {} {0} {}} tawm ntawm ib nrais muag.
| Txojkev | Kev ua yog | Hov ceev | Tus nqi (kwv yees.) | Puas tsuaj? |
| Tua hluav taws | Zoo heev (rau 0.01%) | Qeeb heev (teev / hnub) | Siab ($ 50- $ 150 ib qho kev sim) | Tau |
| XRF Analyzer | Zoo heev (rau 0.1%) | Ceev heev (2-5 vib nas this) | Siab ($ 15k + mus yuav) | Tsis muaj |
| Kuaj hluav taws xob | Pluag (feem ntau ± 1-2k) | Ceev (vib nas this) | Tsawg ($ 150- $ 600) | Tsis muaj |
| Acid / touchstone | Ncaj ncees rau txom nyem | Nruab nrab (feeb) | Tsawg heev ($ 20- cov khoom siv $ 50) | Yog (kos) |
Kev xaiv ib txwm muaj
Thaum XRF thiab hluav taws kub yog qhov tseeb tshaj plaws, lwm yam kev ua si ntau yam. Txawm li cas los xij, lawv cov kev txwv yog qhov tseem ceeb thiab yuav tsum tau to taub ua ntej koj ntseeg lawv rau kev sib pauv nyiaj txiag.
Hauv Cov Ntsuas Kub
Cov cuab yeej siv ua haujlwm ua haujlwm los ntawm kev hla dhau tam sim no los ntawm cov hlau los ntsuas nws cov hluav taws xob conduction. Cov kub sib txawv kub muaj cov qib kev sib txawv, uas lub tshuab siv los kwv yees cov karat.
Qhov teeb meem raug:Cov khoom siv hluav taws xob hluav taws xob qhov tseeb yog nws qhov khuam loj tshaj. Lawv tau yooj yim dag los ntawm kub - plated cov khoom thiab cov hlau ua hlau nrog cov hlau sib xws, xws li cov hlau stainless. Nws tsis yog qhov tsis yooj yim rau cov kev sim no kom raug tawm los ntawm ib lossis txawm tias ob qho tib si Karats, uas ua rau muaj qhov tseem ceeb rau qhov tseem ceeb.
Kev Txiav Txim Siab:Cov no tsuas yog siv los ua cov cuab yeej kuaj pom yooj yim los cais pom tseeb tsis {}} cov khoom kub los ntawm cov peev txheej kub.Tsis txhob cia siab rau ntawm cov kws ua tes hluav taws xob los txiav txim siab tus nqi ntawm ib yam khoom.
Cov tsoos acid & touchstone
TusKev kuaj kub nyiajyog txoj kev qub tshaj plaws. Nws cuam tshuam nrog cov khoom ntawm lub pob zeb dub (ib to Koustone) thiab thov cov kua zog sib txawv ntawm nitric acid rau cov streak. Tus neeg siv tshuaj xyuas cov tshuaj lom neeg siv tshuaj rau kwv yees cov kub lub karat.
Qhov teeb meem raug:Hom no yog cov kev xav zoo siab thiab nyob ntawm tus neeg siv kev kawm thiab kev paub dhau los. Nws tsis yog meej, tsuas yog muab cov lus cog tseg, thiab yog suav hais tias yog ib nrab, thiab yog kev puas tsuaj vim tias nws khawb qhov khoom. Cov kua qaub kuj muaj kev puas tsuaj thiab yuav tsum ua tib zoo tuav.
Kev Txiav Txim Siab:Nws yog qhov kev xeem pheej yig tshaj plaws thiab tuaj yeem pab tau rau kev txheeb xyuas cov seem scrap kub. Txawm li cas los xij, nws yog ib qho txheej txheem qub thiab cov txheej txheem tsis muaj kev ntseeg tau rau kev ua haujlwm hauv kev teeb tsa niaj hnub.
Yooj yim ntawm -}} Kev Ntsuas Hauv Tsev Hauv Tsev
Yog tias koj tsuas xav pom qhov tseeb pom tseeb, kev ntsuam xyuas qee zaum yooj yim tuaj yeem pab tau.
Tsis paub tseeb:Cov hau kev no tsis muaj tseeb thiab tuaj yeem ua tsis tau. Lawv yuav tsum tsis txhob siv tus nqi rau ib yam khoom. Lawv tsuas yog pab txheeb xyuas qhov tsis - cov khoom kub.
Magnet xeem:Kub tsis sib nqus. Yog tias koj cov khoom siv nrog lub hlau nplaum, nws tsis yog cov kub. Txawm li cas los xij, qee qhov fakes siv tsis- Cov hlau me me yuav muaj lub caij nplooj zeeg steel, yog li qhov kev ntsuas no tsis yog neeg dag.
Cov nqi ntsuas ntom:Kub yog ib qho ntawm cov hlau densest. Koj tuaj yeem kwv yees qhov ntom ntom siv cov txheej txheem dej Qhov no yuav tsum muaj qhov ntsuas tau raug thiab ua tib zoo ntsuas, thiab nws tuaj yeem nyuaj rau kev ua cov khoom nrog cov khoom uas muaj hollow lossis goodstones.
Kev Ntsuam Xyuas Pom:Saib rau cov cim npe lossis cov nyiaj muas cim qhia lub karat (piv txwv li, 10k, 14k, 750, 585). Nco ntsoov tias cov nyiaj muas no tuaj yeem tso tau yooj yim tau tso rau ntawm cov cuav.
Dab tsi yogTus ntsuas kub zoo tshaj plawsRau koj?
Xaiv tus neeg ntsuas txoj cai nyob ntawm koj daim ntawv thov, nyiaj txiag, thiab cov khoom raug.
Rau cov tub txawg (Jewelers, refiners, pawn khw):IbXRF Analyzeryog tus qauv kev lag luam niaj hnub. Kev nqis peev yog qhov tsim nyog rau kev tswj kom muaj kev tswj hwm qhov raug, kev ua haujlwm ceev, thiab, tseem ceeb tshaj plaws, cov neeg siv khoom ntseeg. Nws tshem tawm cov kev tsis sib haum thiab tiv thaiv koj txoj kev lag luam los ntawm cov yuam kev raug yuam kev.
Rau cov tub lag luam loj thiab cov neeg sau khoom:Rau kev ua kom zoo - tus nqi bullion thiab chanismatic npib, ib txwm hloov nrog cov tswv yim uas siv cov qauv pov thawj xws li XRF lossis Ultrasonic kuaj. Yog tias koj cov peev nyiaj tso cai rau kev txheeb xyuas tus kheej ntawm kev sau loj loj, ib lub tshuab XRF muab kev thaj yeeb ntawm lub siab.
Rau hobbyists & me - nplai muag:Kev sib xyaw ua ke ntawm qhov yooj yim ntawm - Kev kuaj hauv tsev tuaj yeem pab cov fakes. Rau qhov muaj nuj nqis seem, cov khoom siv suab txhim khu kev qha acid yog qhov pib. Rau txhua qhov tseem ceeb ua lag luam, nws yog ib txwm xav kom them tus nqi me me rau lub zos kev ntseeg siab ntawm Jeweler rau kev kuaj XRF. Zam kev txiav txim siab nyiaj txiag raws li cov tshuab hluav taws xob pheej yig.
