Firstly, nws yog qhov tsim nyog tsim qauv, txiav txim siab, thiab tsim cov pwm. Cov khoom siv raw yog tsuas yog quartz xuab zeb, thiab lwm cov ntaub ntawv ib pab pawg tau yaj mus rau hauv lub xeev ua kua thaum kub. Tom qab ntawd, nws tau txhaj rau pwm, txias, txiav, thiab tempered los ua lub khob iav. Cov moulding ntawm cov iav fwj tuaj yeem faib ua peb hom raws li txoj kev ntau lawm: Kev tuav tshuab, tshuab tshuab, thiab extrusion molding. Cov fwj iav tuaj yeem faib ua cov hauv qab no raws li lawv cov lus sib xyaw: sodium calcium iav, txhuas iav, thiab borosilicate iav.

Cov khoom siv raw tseem ceeb rau cov iav fwj yog ntuj los yog cov dej qab zib, thiab tsis muaj kev hloov pauv ntawm cov khoom siv ntau tshaj plaws thaum muaj tshuaj lom neeg ntau tshaj plaws. Nws cov txheej txheem tsim tau yooj yim, tus duab yog hloov tau thiab hloov tau yooj yim, nws yog cua sov, yooj yim, yooj yim, yooj yim, muaj cov yam ntxwv ntawm kev rov ua haujlwm. Cov fwj iav, uas yog siv ntim khoom, yog siv cov roj, dej caw, tshuaj pleev roj, thiab muaj ntau yam kev siv. Tab sis iav fwj tseem muaj lawv cov teeb meem, xws li qhov hnyav, kev thauj mus los siab thiab tsis muaj nqi tiv thaiv.

Cov kev siv cov yam ntxwv siv thiab cov fwj iav: cov fwj iav yog cov ntim ntim ntim rau hauv cov zaub mov, tshuaj, thiab kev lag luam siv tshuaj lom neeg. Lawv muaj cov tshuaj ruaj khov zoo; Yooj yim mus foob, cov cua zoo, pob tshab, thiab cov xwm txheej ntawm cov ntsiab lus tuaj yeem pom ntawm sab nraud; Kev khaws cia zoo; Du nto kom yooj yim ua kom yooj yim thiab kom tsis muaj menyuam; Zoo nkauj tsos, nplua nuj thiab muaj xim zoo nkauj; Muaj qee yam siv zog muaj zog thiab tuaj yeem tiv thaiv lub siab hauv lub raj mis thiab sab nraud yuam kev thaum thauj mus los; Qhov zoo ntawm kev faib tawm cov ntaub ntawv raw thiab cov nqi qis. Nws qhov tsis zoo yog qhov siab zoo (huab hwm coj kom muaj peev xwm), siab brittleness, thiab ntshav taus. Txawm li cas los xij, nyob rau hauv xyoo tsis ntev los no, thev naus laus zis tshiab xws li lub cev nqaij daim tawv nyias muaj nyias lub cev thiab cov kev ua tsis tau zoo tau txais kev txhim kho. Yog li, iav fwj tuaj yeem ua rau lawv cov xyoo ua haujlwm ntau dua los ntawm kev sib tw ua ke nrog cov caterate yas, thiab cov kaus poom hlau.

Muaj ntau cov iav fwj ntau, los ntawm lub zog me me nrog lub peev xwm loj ntawm kaum li ntawm lub zog, los ntawm cov muaj xim thiab pob tshab amber, ntsuab, xim xiav Opaque fwj, thiab opaque opaque iav fwj, rau npe ob peb. Nyob rau hauv cov nqe lus ntawm kev tsim khoom siv tshuab, cov fwj iav feem ntau muab faib ua ob pawg: siv cov thawv fwj (uas siv iav raj fwj). Moulded fwj tau muab faib ua ob pawg: lub raj mis loj (nrog lub qhov ncauj ntawm ntau tshaj 30mm) thiab cov caj dab me me. Tus qub yog siv los tuav hmoov, thaiv zoo li, thiab muab tshuaj txhuam zoo li cov khoom, thaum lub tom kawg yog siv los tuav kua. Raws li daim ntawv ntawm lub raj mis, nws tuaj yeem faib ua cork cork qhov ncauj, lub raj mis lub raj mis lub qhov ncauj, thiab lwm yam raws li kev siv "uas yog pov tseg ib zaug thiab "rov qab fwj" uas tau siv ntau zaus. Raws li kev faib tawm cov txheej txheem, nws tuaj yeem faib ua cov raj mis, cov hwj dej hauv taub hau, cov hwj dej hauv taub hau, cov hwj dej hauv taub hau, infusce fwj, tshuaj pleev ib ce, thiab lwm yam
