Daj Kub - unsurpassed classics

Daj kub - yog dab tsi? Nws yog tsis zoo li tias tej yam peb tsis paub cov lus teb rau lo lus nug no. Nws yog qhov tseeb los ntawm centuries classic uas mus tawm ntawm fashion puas tau. Qhov no hlau tsis tau tsis meej pem nrog lwm yam, ornaments los ntawm nws cov txhua lub sij hawm.
Daj kub (cov duab no muaj nyob rau hauv tsab xov xwm) - ib tug noble hlau, uas tsis muaj feem xyuam rau lub siab kub, ya raws los yog huab cua.

thaj chaw ntawm kub

Nyob rau hauv cov xwm, cov hlau nyob rau hauv daim ntawv ntawm cov grains uas muaj kos nyob rau hauv quartz thiab quartz xuab zeb. Kub muaj ib tug high ductility thiab malleability. Nyob rau hauv cov ntshiab hauv daim ntawv ntawm cov hlau yog heev mos mos, nws yuav txiav nrog ib tug riam yooj yim. Cov khoom ua los ntawm cov tseem kub yog puas yooj yim thiab yooj yim nraus. Qhov no yog qhov zoo zoo nkauj tshooj hlau uas muaj ib yam kaj daj xim. High gloss yog nws cov yam ntxwv feature. Kub siab ductility, nyob rau hauv qhov siv thiab ua hniav nyiaj hniav kub nyob rau hauv thiaj li yuav txhim kho yam ntxwv lub cev ntawm lub impurity ntxiv thereto, thiab lwm yam co, uas raug xa mus rau raws li nyuam.

Yuav ua li cas yog ib tug qauv kub?

Tus qauv ntawm kub - tus piv nyob rau hauv lub hlau thiab tus nqi ntawm cov tseem kub ligatures (impurities). Tooj thiab nyiaj yog suav hais tias yog qhov zoo tshaj plaws impurities. Nyob rau hauv peb lub teb chaws, li ib txwm yog muab hais txog zauv tseem ceeb ntawm ib tug qauv uas ua los ntawm kub. Tus nqi uas qhia tus naj npawb ntawm cov hlau daim yog 1000 alloy daim. Piv txwv li, yog hais tias tus khoom no yog 750, nws txhais tau tias alloy muaj 1000 g 750 g ntawm dawb huv kub.

Daj Kub 585: muaj pes tsawg leeg ntawm lub alloy

Qhov no yog ib qho hlau raws li nyob rau hauv kub. Ntxiv Cheebtsam (ligatures) nyob rau ntawd yog nyiaj thiab tooj liab. Daj Kub 585 formulation muaj cov nram qab: dawb huv kub - 58,5%, lwm yam co - 41,5%. Cov xim ntawm cov khoom cuam tshuam los ntawm tus nqi ntawm cov ntsiab. Nyob rau hauv lub teb chaws ntawm lub qub Soviet Union siv ntau tooj liab, ua lub alloy yuav reddish. Nyob rau hauv Teb chaws Europe, peb muab nyiam rau nyiaj. Yog li ntawd, cov nyob sab Europe kub Hawj txawm es txiv qaub. Nws yuav tsum tau muab sau tseg tias vim nyob tus yeees ntawm tus tswv hlau daj kub, uas yog ua nyob rau hauv ib ncig ntawm lub qub USSR, muaj ib tug ntau dua lub zog piv nrog rau European. Thawj cov xim - daj, tab sis vim qhov no hlau yog heev mos mos, cov khoom ntawm cov tseem kub ua xwb nyob rau hauv Nyiv. Nyob rau hauv lub teb chaws no, rau zus tau tej cov hniav nyiaj hniav kub ua los ntawm kub siv nyob rau hauv yuav luag ntshiab daim ntawv. Yuav kom jewels tsis tau poob lawv lub thawj tsos, hnav lawv tsis tshua muaj thiab ua tib zoo muab cia rau hauv tshwj xeeb uas tsim mob. Tus qauv tsis yog nyob ntawm seb cov xim. Feem ntau nyob rau hauv peb lub teb chaws, daj kub 585, raws li los ntawm 750 alloy. Tej kuaj raws li 500, 375, 583, muaj tam sim no heev tsis tshua muaj.

Lwm yam hniav nyiaj hniav kub alloys

• Liab kub. Nyob rau hauv lub hniav nyiaj hniav kub kev lag luam ntawm lub qub Soviet Union yog tus loj ntawm zoo zoo nkauj tshooj raws nraim nws. Nws twb tseem hu ua "Lavxias teb sab kub".
