Peb txhua tus paub ntau txog cov khoom siv lead ua pendant, xws li bracelets, necklaces thiab tsej, uas yog nrov heev rau cov ntxhais. Ib feem loj ntawm qhov laj thawj yuav tsum yog qhov xwm txheej ntawm crystal. Crystal yog ib hom pob tshab thiab tsis muaj xim, uas yuav cuam tshuam lub teeb nyob rau hauv lub hnub. Yog li ntawd, siv lead ua kuj tau siv dav hauv kev lag luam. Cia saib seb puas muaj ntau hom siv lead ua.
Muaj ntau hom pob zeb siv lead ua
Raws li nws tsim, nws tuaj yeem faib ua cov hauv qab no:
1. Ntuj siv lead ua pob zeb:
Ntuj siv lead ua yog tsim nyob rau hauv tej yam kev mob. Nws loj hlob tob rau hauv lub ntiaj teb crust. Nws feem ntau yuav siv cov kev ua phem ua phem xws li roob hluav taws thiab av qeeg los tsim. Ntuj siv lead ua yog cov ntxhia pob zeb. Nws yog qhov tsawg heev thiab muaj nuj nqis heev. Nws yog ib qho ntawm cov gemstones.
2. Synthetic siv lead ua:
Synthetic siv lead ua pob zeb tseem hu ua regenerative siv lead ua pob zeb. Nws yog ib qho siv lead ua, tseem hu ua hluavtaws siv lead ua thiab piezoelectric siv lead ua. Regenerated siv lead ua yog tsim los ntawm "imitating txoj kev loj hlob ntawm ntuj siv lead ua" los ntawm hydrothermal crystallization, muab natural silicon ore thiab ib co tshuaj nyob rau hauv ib tug autoclave thiab maj cultivating lawv nyob rau lub sij hawm ntawm 1-3 hli.
Tom qab ua tiav, cov khoom siv lead ua pob zeb ntawm ntau cov duab yog crystal ntshiab, dazzling, hnav-resistant thiab corrosion-resistant.
3. Molten Crystal:
Cov pob zeb siv lead ua no feem ntau yog yaj nrog siv lead ua pov tseg raws li cov khoom siv raw hauv qhov kub thiab txias, tsis yog crystallized. Yog li ntawd, nws tsis muaj cov yam ntxwv ntawm cov khoom siv lead ua. Lub melted crystal yog resistant rau kub kub. Cov khoom siv lead ua melted nrog zoo silicon dioxide tuaj yeem ua rau cov khoom siv tau zoo, xws li cov khob siv lead ua, ci lauj kaub, tshuaj yej teeb, thiab lwm yam.
4. K9 iav imitation siv lead ua:
Txawm hais tias K9 iav yog yaj nrog silicon dioxide raws li cov khoom siv tseem ceeb, 24 feem pua cov hmoov lead yog ntxiv rau hauv cov txheej txheem melting, uas yog cov iav txhuas.
Cov saum toj no yog hais txog kev faib cov crystals. Koj puas tau nkag siab nws? Peb yog cov iav siv lead ua lag luam tshwj xeeb hauv kev tsim cov qib qis, nruab nrab thiab qib siab. Tam sim no, txhawm rau txhim kho peb cov khoom lag luam zoo thiab cov npe lag luam, peb ua cov lus piav qhia saum toj no. Yog tias tsim nyog, thov koj xav tiv tauj peb!
