Lub raj mis iav yog daim ntawv thov ntawm laminated iav raw khoom tsim cov fwj dej, alias iav fwj.
Muaj ntau ntau xim sib txawv ntawm cov iav fwj, muab faib ua pob tshab iav fwj, emerald ntsuab iav fwj, kas fes iav fwj, iav fwj tsaus xiav, tsaus ntsuab iav fwj, thiab lub hwj iav ntsuab.
Nyob rau theem no, daim ntawv thov txheej txheem ntawm pob tshab dawb iav fwj yog dav heev, muaj ntau hom khoom, thiab kev muag khoom xav tau tshwj xeeb yog loj.
Cov ntaub ntawv tseem ceeb rau kev tsim cov iav fwj yog xaiv quartz xuab zeb, ammonium bicarbonate, dolomite, dolomite hmoov, boro xuab zeb, sodium nitrate, dolomite, iav slag, thiab lwm yam ntau tshaj kaum hom raw khoom npaj rau do thiab tawg. cov ntaub ntawv raw khoom sib npaug. Lub peev yog muab tso rau hauv lub pas dej ua ke kiln sab hauv txoj kab uas hla ntawm 1550 degree --1600 degree Qhov concentration ntawm cov khoom melting ua rau cov ntaub ntawv raw dissolve rau hauv laminated iav kua dej tshuaj. Tom qab ntawd los ntawm cov khoom siv tshuab pub noj kom ua tiav kev tsim khoom ua haujlwm.
Pob tshab dawb iav fwj kuj tuaj yeem pleev xim rau hauv lub khob iav ntsuab, lub raj mis kas fes, lub raj mis ntsuab, thiab lwm yam.
Nws tseem tuaj yeem ua rau saum npoo ntawm pob tshab iav fwj.
Cov iav fwj tam sim no nrov dua hauv kev muag khoom lag luam thiab kev tiv thaiv ib puag ncig ntawm cov khoom ntim cov hlab ntsha, cov thawv tsim kho kom zoo nkauj, thiab cov iav laminated iav, daim ntawv thov ntawm laminated iav ua kuj tseem pheej yig dua ntim cov ntaub ntawv raw.
Cov iav uas ua los ntawm cov iav laminated yog ib txoj haujlwm tseem ceeb hauv kev ntim khoom noj thiab dej haus.
Cov iav fwj tuaj yeem siv rau hauv cov ntim dej haus, ntim dej haus, ntim roj nyoos, ntim cov txiv hmab txiv ntoo, ntim cov alkali, ntim tshuaj, iav beaker, ntim ntim, thiab ntim cov khoom tu tawv nqaij.
