Lub ntsiab lus uas siv lead ua K9

Aug 22, 2015

K9 siv lead ua, hu ua iav K9, yuav xa mus rau lub K9 siv lead ua trophies yog ua los ntawm cov ntaub ntawv rau txheej kho qhov muag thiab lwm teb, los ntawm lub teeb kis, refraction, hardness thiab kev ntxhib los mos kom deb deb saum tus cob khoom tawg yooj yim. Ntxuav cov mas tej polishing thiab siab-cam khwb cia (raug melting lauj kaub). K9 khoom kho qhov muag iav, crystal tseeb, tug derived K9 siv lead ua trophy mus ntxuav cov kwv factories, cov khoom uas lawv khiav, hu ua Crystal Medal khoom rau lub lag luam ntau heev.

K9 iav EU rhinestones (siv lead ua) tus thawj txhais yog cov ntsiab lus PBO ntau tshaj 24%. K9 iav tsis muaj PBO, refractive indexes mus rau lub refractive index iav uas muaj hmoov txhuas.

Vim li cas muaj muag K9 K9 siv lead ua neeg tsim trophy yog siab txog qib uas ntau lawm, Suav teb twb tsis muaj cov kev cai ntawm Rhinestones, b txim uas siv lead ua iav siv lead ua uas tsis muaj tseem ua trophy yog ua los ntawm taug txhuas siv lead ua manufacturers.

Hauv qab no yog cov EU raws li txoj cai lub ntsiab lus dag siv lead ua, nyob hauv lub teb chaws txawv teb chaws, yog hais tias koj siv K9 iav tau thov kom muab siv lead ua los muag, luag yuav qhia rau koj.

S.I. No. 312/1972 — cov zej zog nyob sab Europe (CrystalGlass) Regulations, 1972.

Meem nias cov siv lead ua muaj ua — — 30% oxides hlau (%) PbO≥ 30% Density≥ 3·00 Refractive index nD > 1·545

Ua siv lead ua — — 24% oxides hlau (%) PbO≥ 30%

Ua raws li cov European Union hlau lead 1972 oxide kawm ntau dua los yog nce mus rau 30%, tus ceev ib yam li 3G/cm3, refractive index ntau dua los yog muab 1.545 iav siv lead ua tag nrho txhuas, hlau lead oxide kawm ntawd ntau dua los yog muab mus iav 24%, ua iav siv lead ua, siv lead ua tsis meej txhais, feem ntau cov hlau lead-iav ua cov ntsiab lus ntawm qhov tsawg tshaj 24% oxide. Muab tso ntawm taug txhuas oxide kawm ntawd ntau dua los yog muab mus iav 24% tshem iav, yuav tau hu rau siv lead ua thiab ua oxide kawm ntawd ntau dua los yog muab 24% tus pub cov tais diav iav iav hu ua hmoov txhuas siv lead ua, ntau dua los yog muab lub 30% ntawm cov iav mus hu ua daim ntawv qhia txog cov hlau lead siv lead ua, yuav tsis tau ntxiv cov iav.
