Iav hlaws dai, ib qho khoom siv tes ua khoom siv, tau siv dav hauv ntau yam khoom dai, khoom ua si, thiab cov khoom ua si. Txawm li cas los xij, ntau tus neeg yuav muaj kev nkag siab tsis meej txog cov ntaub ntawv siv los ua cov iav hlaws. Kab lus no yuav delve rau hauv lub ntsiab Cheebtsam ntawm iav hlaws dai thiab teb cov lus nug uas muaj lawv cov ntaub ntawv.
Ua ntej, nws yog ib qho tseem ceeb kom paub meej tias iav hlaws iav tsis yog ua los ntawm cov hlau. Lawv lub koom haum tseem ceeb yog silicates thiab lwm yam tshuaj, uas, thaum melted ntawm qhov kub, ua ib qho iav. Qhov yeeb tshuaj molten no tuaj yeem tuaj yeem muab pwm rau hauv ntau yam duab, suav nrog cov hlaws pleev iav.
1. Cov ntaub ntawv siv hauv iav hlaws
Iav hlaws dai yog feem ntau ua los ntawm quartz xuab zeb (feem ntau tsim ntawm silicon dioxide), dej qab zib (sodium carbonate), thiab limestone (calcium carbonate). Cov ntaub ntawv no, thaum melted ntawm cov kub, ua kua tsom iav ua kua. Los ntawm cov txheej txheem tshwj xeeb, cov kua no tau poob rau hauv dej txias, ua rau nws mus nrawm nrawm thiab solorify, yog li ua cov iav hlaws dai.
2. Kev ua neeg tsis paub txog kev sib xyaw ntawm nws yog xim hlau
Qee tus neeg yuav ua yuam kev ntseeg tias iav hlaws dai muaj cov hlau me me, feem ntau vim lawv cov lus qhia thiab kev ntxhib los mos. Txawm li cas los xij, lub ci ci thiab tawv ntawm iav hlaws dai yog txiav txim siab los ntawm lawv cov iav muaj pes tsawg leeg thiab tsis muaj dab tsi ua rau cov hlau. Qhov tseeb, hlau thiab iav yog ob cov ntaub ntawv sib txawv, nrog cov khoom sib txawv ntawm lub cev thiab tshuaj lom neeg.
3. Cov iav hlaws tsim cov txheej txheem
Lub iav cog tsim cov txheej txheem feem ntau yog cov kauj ruam hauv qab no: batching, melting, sib sau, txias, thiab ntim. Thawj zaug, cov ntaub ntawv tsim nyog tau xaiv thiab ua pob raws li qhov xav tau. Tom qab ntawd, cov khoom xyaw tau melted rau daim iav ua kua. Cov kua ua kua yog tso rau hauv dej txias uas siv cov khoom siv tshwj xeeb kom sai thiab tsim cov iav hlaws. Thaum kawg, cov hlaws iav tsim tau ntxuav, tshuaj ntsuam, thiab ntim rau kev muag khoom.
4. Kev thov ntawm iav hlaws
Vim yog lawv lub cev thiab tshuaj lom neeg tshwj xeeb thiab tshuaj lom neeg, iav hlaws iav muaj ntau cov ntawv thov. Piv txwv, hauv cov tsheb thauj mus los, cov hlaws iav feem ntau yog siv los ua cov ntaub ntawv muaj kev nyab xeeb los txhawb kom muaj kev nyab xeeb hmo ntuj. Hauv kev kho kom zoo nkauj, xim iav hlaws iav tau siv tau raws li cov khoom siv ua tau zoo. Lawv tseem muaj dav siv raws li cov avasives thiab fillers.
