Qhov txawv ntawm iav thiab siv lead ua

Jan 18, 2019

Synthetic quartz thiab tshuaj lom neeg muaj pes tsawg leeg ntawm ntuj Crystal silica, siab purity silicon dioxide uas yog hu ua "Crystal". Ntuj Crystal yog pob zeb ua pob tshuam los ntawm cov xim pob zeb uas yog hexagonal column crystals, nws qhov kev kub ntxhov siab heev, rov qab lub hnub ci (feem ntau hu ua xya rays), muaj zog heev.

Ntshiab quartz yog tsis muaj xim tsis muaj pob Crystal, tsis muaj kev qoj ntawm ntuj Crystal yuav tsis tshua pom cov huab cua tshaj plaws nrog cua npuas thiab impurities, Crystal mixing corrosion.


Synthetic quartz raw cov ntaub ntawv raw silica xuab zeb los ntawm cov txheej txheem kev ntxhib, ces los ntawm lub tshuab txiav nplua thiab zoo kiag li flawless polished kev ua, ua dawb huv pob tshab crystals, tsim rau lub deficiency ntawm ntuj siv lead ua.


Rhinestones ntxiv cov hlau xws li cov hlau lead tuaj yeem ua kom pom kev sib tw, tsuas pom tias Crystal ntawm nobility. Vim yog cov khoom siv Crystal txoj kev nyuaj, cov paj ntaub zoo tshaj plaws, qee tus nqi tseem kim tshaj li qhov siv lead ua.


Crystal lead uas yog cov iav uas muaj iav, los yog hlau lead iav thiab iav zoo nkauj (muaj pes tsawg leeg yog silicon dioxide) mus rau 24% lead oxide, yuav zoo ib yam li ntuj Crystal ci ci thiab daim nplaum ntawm Crystal.

Cov txheej txheem thoob ntiaj teb rau cov ntsiab lus ntawm cov lead oxid 24% (uas yog hu ua Crystals, tsawg dua yog cov iav Crystal), thiab tshuaj lom neeg cov khoom siv Crystal qhov zoo tshaj, piv nrog cov iav zoo nkauj, feem ntau loj, hnov hnyav, tawg, kis tawm ntawm cov yeeb yuj kaum xim; highness hardness, hnav-resisting.


UV tuaj yeem nkag mus rau rhinestones thiab Crystal, thaum iav tsis zoo.


Crystal melting point: Crystal melting point 1713


Refractive Performance index: Crystal's refractive index 1.544-1.553, tsis yog tawm ntawm ntau yam. Ris ntub thaum lub teeb ntawm huab cua mus rau hauv Sapphire Crystal, thiab yog lub zog, nws lub kaum ntse ntse thiab qhov piv ntawm sine ntawm lub kaum sab xis.


Thoob ntiaj teb iav tau nruj lub tswvyim ntawm iav: hom iav. Crystal: leaded iav, los yog Crystal, lead oxide cov ntsiab lus ntawm 24%. Yog li ntawd, 24% ua rau cov hlau lead muaj oxide iav.
