K9 Crystal, tseem hu ua K9 iav, kuj tuaj yeem xa mus rau K9 Crystal trophies ua cov ntaub ntawv rau qhov kho qhov muag thiab lwm yam kev lag luam, cov teebmeem ntawm lub teeb kis, kev tawg, kev kho thiab kev ntxhib los kom deb ntawm cov ntaub ntawv cob qhia. Kev ua tsuas yog txiav polishing thiab siab-cam khwb cia (raug melting lauj kaub). K9 cov khoom siv rau cov iav theem kho, siv lead ua, muab ntau heev ntawm K9 siv lead ua lub dav hlau rau cov khoom ua haujlwm, cov khoom ntawm lawv cov ua, hu ua Crystal Medal khoom nyob hauv kev ua lag luam.


K9 iav EU rhinestones (Crystal) thawj lub ntsiab lus yog PBO cov ntsiab lus ntawm ntau tshaj 24%. K9 iav tsis muaj PBO, refractive indexes mus txog rau qhov ntsuas kub ntawm cov iav uas muaj hmoov lead.

Yog vim li cas muag K9 K9 neeg siv lead ua trophy yog qib siab tshaj plaws ntawm kev tsim, Tuam Tshoj tsis muaj txoj cai nyob rau Rhinestones, b yog ua los ntawm lead ua khob kuj ua cov khoom siv lead ua los ntawm lead crystal manufacturers.


Nram qab no yog EU txoj cai txhais ntawm cov khoom siv Crystal, nyob hauv lwm lub teb chaws, yog tias koj siv K9 iav kom lees yuav muag, lwm tus tuaj yeem qhia koj.


SI No. 312/1972 - Cov Neeg Txuas Tebchaws Hauv Lub Tebchaws (CrystalGlass), 1972.


(Lead) Crystal - 30% Cov hlau oxides (%) PbO muaj 30% Qhov ntmis 3 · 00 Refractive index nD> 1 · 545


Lead Crystal - 24% Cov hlau oxides (%) PbO muaj 30%


Kev cai ntawm cov European Union xyoo 1972 coj oxide ntsiab lus siab dua los yog sib npaug li 30%, qhov ceev yog ntau dua li 3/3/3, qhov muag tsis pom siab tshaj 1.545 iav uas muaj cov hmoov lead lead, iav, lead ua lead, kua pleev ua tsis yog raws li qhia meej, feem ntau nrog cov hlau lead iav lead oxide ntsiab lus tsawg dua 24%. Muab kev tso cai ntawm cov hlau lead oxide ntau dua los sis sib npaug li 24% iav tshem tawm cov iav, hu ua Crystal thiab ua cov oxide ntsiab lus siab tshaj los sis sib npaug li ntawm 24% tus iav leaded uas tau paub tias yog lead crystal, ntau dua los yog sib npaug 30% ntawm cov iav pub rau cov hu ua txhuas lead, tsis tas yuav ntxiv khob.
