n xyoo tas los no, nrog kev txhim kho tas mus li ntawm cov cuab yeej tsim khoom thiab kev txhim kho thiab kev loj hlob ntawm kev lag luam kev lag luam, cov neeg tau ua tiav tshiab hauv kev kho kom zoo nkauj. Ntau qhov chaw yuav siv cov cib siv lead ua rau kev kho kom zoo nkauj. Thaum koj hnov cov pob zeb siv lead ua, koj yuav xav tias lawv yog lub cim ntawm khoom kim heev. Raws li kev ua tiav rau ntau lub zos kho kom zoo nkauj, lawv nrov heev. Ntxiv rau cov cib siv lead ua, kuj tseem muaj hom iav cib uas tau siv dav, Tab sis qhov txawv ntawm ob yog dab tsi?
Crystal cib
1. Cov ntaub ntawv sib txawv: siv lead ua yog siv lead ua ntawm silicon dioxide, thaum iav yog sib xyaw ntawm molten silicon dioxide.
2. Cov teebmeem sib txawv: iav tsuas yog muaj kev kho kom zoo nkauj, thaum siv lead ua muaj cov nyhuv piezoelectric ntxiv rau kev kho kom zoo nkauj, uas muaj kev kho mob tshwj xeeb.
3. Cov nqi sib txawv: tus nqi ntawm cov khoom siv lead ua yog ob peb zaug siab dua li cov iav.
4. Cov khoom sib txawv ntawm lub cev: siv lead ua yog cov siv lead ua uas muaj cov tawv tawv siab, thaum lub iav hardness tsawg. Crystal tuaj yeem kos cov cim ntawm lub khob, txwv tsis pub nws ua tsis tau. Crystal yog siv lead ua nrog zoo thermal conductivity. Nws hnov txias thaum kov nrog tus nplaig. Lub khob sov. Nrog lub polarizer, siv lead ua tuaj yeem xa lub teeb, thaum iav tsis tuaj yeem.
5. Cov txheej txheem sib txawv: iav tuaj yeem ua rau kub cam, txuag cov ntaub ntawv, kev ua haujlwm thiab nyiaj txiag. Crystal yog siv lead ua, uas tsis tuaj yeem thim rov qab tom qab cua sov thiab yaj. Yog li ntawd, txoj kev kub casting tsis tuaj yeem siv, thiab txoj kev txias xws li txiav thiab sib tsoo tsuas yog siv tau. Nws siv ntau yam khoom siv thiab kev ua haujlwm, thiab tus nqi siab. Crystal muaj siab hardness thiab tsis yooj yim rau hnav. Cov iav muaj qhov hardness tsawg thiab yooj yim rau khawb. Crystal muaj kev ruaj ntseg zoo thiab yuav tsis hloov xim tom qab siv ntev. Cov iav yog nquag yellowing.
Hauv ib lo lus, siv lead ua cib yog qhov kev xaiv zoo rau kev kho kom zoo nkauj hauv tsev, kho kom zoo nkauj thiab kho kom zoo nkauj ntawm thaj chaw nyob, thiab kuj yog ib qho kev xaiv zoo rau cov txheeb ze thiab phooj ywg muab khoom plig. Cov khoom siv lead ua ntuj yog qhov tseeb thiab huv si, muab cov neeg txias txias, thiab cov khoom siv no muaj zog hardness thiab tsis yooj yim rau kev puas tsuaj. Tau kawg, yog tias koj xav yuav thiab siv nws, koj tuaj yeem xaiv lub chaw tsim khoom lav!
