Yuav ua li cas ua lub raj mis iav

     Lub raj mis iavyog ib lub thawv ntim dej cawv ib txwm muaj nyob rau hauv Suav teb, thiab iav kuj yog ib hom khoom ntim khoom uas muaj keeb kwm ntev. Yog tias muaj ntau hom khoom ntim khoom ntws mus rau hauv kev ua lag luam, lub thawv iav tseem nyob hauv txoj haujlwm tseem ceeb hauv kev ntim dej haus. Thiab nws muaj lwm cov khoom ntim khoom uas tsis tuaj yeem hloov los ntawm cov yam ntxwv ntim khoom sib cais. Tam sim no coj koj mus nkag siab yuav ua li cas ua lub raj mis iav.

1.Cov Txheej Txheem Kev Siv Tshuab

Lublub raj mis cawv iavCov txheej txheem tsim khoom feem ntau suav nrog: 1) Cov khoom siv raw yog ua tiav ua ntej los tsoo cov khoom siv raw thaiv (quartz xuab zeb, soda soda, limestone, feldspar, thiab lwm yam) kom qhuav cov khoom siv raw ntub, thiab tshem tawm cov hlau uas muaj cov khoom siv raw kom ntseeg tau tias qhov zoo ntawm iav. 2) Kev npaj cov khoom sib xyaw. 3) Kev tsim kho. Cov khoom sib xyaw iav raug cua sov ntawm qhov kub siab (1550 ~ 1600 degrees) hauv lub tank kiln lossis lub cub tawg, ua rau nws tsim cov khoom sib xws tsis muaj npuas, thiab ua tau raws li qhov yuav tsum tau ua ntawm cov iav kua. 4) Puab. Muab cov iav kua rau hauv pwm kom ua cov khoom iav xav tau, xws li cov phaj, cov khoom siv, thiab lwm yam. 5) Tempering. Los ntawm annealing thiab quenching thiab lwm yam txheej txheem, tshem tawm lossis tsim cov theem kev ntxhov siab sib cais lossis crystallization hauv iav, thiab hloov pauv lub xeev ntawm cov iav.

2. Kev Ua Haujlwm

 Kauj ruam thawj zaug yog tsim, txiav txim siab thiab tsim cov pwm, Cov khoom siv iav raw yog quartz xuab zeb ua cov khoom siv tseem ceeb, thiab lwm yam khoom siv pabcuam raug yaj rau hauv cov kua ntawm qhov kub siab, thiab tom qab ntawd txhaj rau hauv cov pwm, txias qhov txiav thiab tempering, thiab lub raj mis iav tau tsim. Lub raj mis iav feem ntau muaj cov cim nruj, cov cim kuj ua los ntawm cov pwm zoo li lub raj mis iav molding raws li txoj kev tsim khoom tuaj yeem faib ua tes tshuab tshuab thiab extrusion molding peb. Raws li cov khoom sib xyaw ntawm cov fwj iav tuaj yeem faib ua cov hauv qab no: ib qho yog sodium iav, ob yog txhuas iav, peb yog borosilicate iav.

Cov ntaub ntawv tseem ceeb ntawm cov fwj iav yog cov pob zeb ntuj, pob zeb quartz, caustic soda, limestone thiab lwm yam.Lub raj mis iavCov fwj iav no pob tshab heev thiab tiv taus xeb. Kev sib cuag nrog feem ntau cov tshuaj lom neeg yuav tsis hloov cov khoom siv. Nws cov txheej txheem tsim khoom yooj yim, cov duab yog dawb thiab hloov pauv tau, qhov nyuaj yog loj, qhov kub tsis kam yog huv thiab yooj yim los ntxuav, thiab nws tuaj yeem siv ntau zaus. Tab sis lub raj mis iav kuj muaj nws qhov tsis zoo, xws li qhov hnyav loj, tus nqi khaws cia thauj khoom siab, kev cuam tshuam tsis kam thiab lwm yam.
