Qhov txawv ntawm cov iav siv lead ua dag thiab cov

May 26, 2016

Ntawd siv lead ua dag yog iav ua, los yog hu ua siv lead ua iav, uas zoo tib yam iav (silica tivthaiv) tau ntxiv 24% ua oxide, nws yuav tau brightness thiab transparency zoo xws li siv lead ua siv lead ua tej yam ntuj tso dag.

Txheem nta tseev tsim ntiaj teb ua oxide ntawv 24%, ces cov tshuaj khoom ntawm tus zoo neeg tsim siv lead ua, piv nrog zoo tib yam iav, hnyav mas, xav ntau hauv; lub refractive loj index yuav kis tau ntawm kaum yeeb yuj spectrum of xim; siab hardness, coj.

Siv uas muaj 24% ua iav oxide hmoov txhuas los ntawm refining, impurities, cua tshuab, tes polished, fine carving, yuav qhia kom paub high-grade zoo ua iav Art, lub teeb duab puab ntawm seb yuav muaj kev cuam tshuam cov xim.

Thoob ntiaj teb qauv mus iav muaj tswvyim nruj, yog iav: cov khoom zoo tib yam iav. Siv lead ua: ua iav los yog hu ua siv lead ua nrog cov hlau lead oxide ntawv 24%. Yog li ntawd, muaj 24% hlau lead oxide kev zoo taug txhuas iav lav.


Uas siv lead ua dag VS iav


Dag siv lead ua iav uas muaj oxide txhuas, hlau lead uas muaj oxide muaj pes tsawg leeg, ntau dua qhov lub refractive index thiab hardness, qhov zoo ntau refined cov ntshiab siv lead ua, thaum tus nyuaj hlais, tas cov ntau tsawg tsawg. Yog li kev zoo tib yam iav los yog siv lead ua tais hab siv lead ua qhov sib txawv ntawm tus nqi ntawm qhov uas tsis muaj kawm ntawv refractive yog zoo kawg thiab.


Mloog lub suab los ntawm cov tes flicking tais diav hnov lub suab yuav khoom uas siv lead ua txawv, co, crisp suab, li hlau zoo li thaum muaj tej yam yuav muaj yuav tau nyob ib cig puas uas muaj cov xov suab "clang clang" suab, qhov yooj yim dua rau cov hardness siv lead ua suab nrov louder. Thiab cov khoom uas iav suab hnyav txhaws, tsis ncha, yog ib tug ntxiv tho txawv "nrov plig plawg" suab.


Ci iab tshav piv rau siv lead ua zoo saib no qhia cov xim sib, xim kaj thiab txoj kev hloov mus kawg ntuj kaj thiab nplua nuj xim iav refraction yog feem ntau tsis tag thiab kuj qauj le. Transparency nyob ntuj sib piv rau cov zoo siv lead ua transparency, uas qhia siv lead ua dawb, hos cov iav zoo tib yam lossis siv lead ua ntshiab yuav daj los yog mixed cyan.


Rau cov ntawv muaj tseeb rau cov qub teeb fineness ntawm tus siv lead ua, tus qauv ntawm cov siab tshaj qhov txawv ntawm ib cheeb tsam ntawm finer txawv taus txoj, ntau dua qhov nqi no. Stroking, tes tsuj taw nto ib txhais tes ntxhib kev txiav txim zoo ballast, thiab yog tus mechanism tsuj taw nto du.


Txij hardness tshaj yog tus hardness ntawm tus siv lead ua ntau dua iav zoo tib yam, yog mus sij hawm ntev siv feem ntau tsis muaj moj, hos cov iav uas pheej siv tau ntev, yog yooj yim heev mus khawb thiab nto soiling li. Siv lead ua dag tshaj qhov hardness ntawm cov iav yuav loj, thiab vim li no, yuav cia tej qhov cim tseg ib Literature nrog nto iav siv lead ua dag, hos tsis zoo li no siv lead ua iav khawb tias yuav tshwm sim.


Luj kev hnyav hnyav: ob yam khoom uas muaj cov me me ib yam, siv lead ua dag no ntau npaum li cas hauv dua iav.
