Koj tuaj yeem qhia tau li cas yog cov hlaws siv lead ua tiag tiag?
1. Kom hnov qhov kub, koj tuaj yeem sim tuav cov siv lead ua hauv koj txhais tes.Tom qab li 2 ~ 3 feeb, koj tuaj yeem hnov tias cov siv lead ua sov los yog txias.Yog tias nws txias, nws yuav muaj tseeb, thiab qhov kub thiab txias hloov sai yog qhov zoo li cov hniav nyiaj hniav kub xws li iav..
2. Kev soj ntsuam pom Cov Crystals yog tsim nyob rau hauv cov xwm, thiab yuav inevitably raug cuam tshuam los ntawm ib puag ncig.Nws yog ib txwm ntxiv impurities.Yog tias koj tuav lub hnub ci rau lub hnub, thiab pom cov kab txaij me me lossis cov khoom zoo li catkin, nws zoo li yuav yog ib qho siv lead ua tiag tiag.Fake crystals feem ntau yog dawb huv thiab niaj hnub vim tias lawv tau ua tiav.
3. Ntsuam xyuas qhov hardness Vim tias ntuj crystals yog ib qho nyuaj thiab tsis yooj yim rau khawb, peb tuaj yeem sim kos cov siv lead ua nrog pob zeb kom pom tias muaj cov kab nyob sab laug.Yog tias muaj cov kab mob, nws yog cov siv lead ua cuav.
Dab tsi yog qhov txawv ntawm iav thiab siv lead ua hlaws?
"Kev tsim cov iav thiab siv lead ua hlaws yog cov txheej txheem zoo heev.Nyob rau hauv nws daim ntawv yooj yim tshaj plaws, iav yog molten xuab zeb, uas yog tov nrog ntau yam additives thiab txias kom sai heev uas nws tsis muaj sij hawm los tsim ib tug crystalline qauv.Thiab nyob rau hauv lub xeev cov khoom, silica xuab zeb Mixed nrog ib tug alkaline tshuaj xws li dej qab zib tshauv kom txo lub melting point ntawm iav xuab zeb kom nws yog yooj yim mus ua hauj lwm nrog.Soda tshauv ua rau cov dej sib tov soluble uas tsis yog qhov xav tau.Ntxiv txiv qaub tau los ntawm limestone kom thim rov qab cov nyhuv no.Cov iav yog molten xuab zeb, ua ke nrog cov additives thiab txias.Tom qab ntawd hauv lub xeev ua kua ntawm 2700 degrees Fahrenheit (1500 degrees Celsius) lossis siab dua, qhov sib xyaw no tuaj yeem ua kom zoo nkauj thiab ua haujlwm ntawm ib qho ntawm ntau txoj hauv kev.
