Peb feem ntau siv cov khoom iav ntau yam hauv peb lub neej, xws li iav qhov rai, tsom iav, iav cov khoom siv iav yog ob qho zoo nkauj thiab cov tswv yim. Lub khob khob yog ua los ntawm quartz xuab zeb ua cov ntaub ntawv tseem ceeb tau muab hliv rau hauv cov pwm, thiab tom qab ntawd cov roj tseem ceeb, thiab tom qab ntawd, txiav, thiab tempered los ua lub khob iav. Cov fwj iav feem ntau muaj lub logo rigid logo, thiab lub logo tseem ua los ntawm cov pwm puab. Raws li kev tsim qauv, cov moulding ntawm cov fwj khob tuaj yeem faib ua peb hom: Kev Ceev Tshuab, Tshuab Tshuab thiab Extrusion Tshuab. Cia peb saib ntawm cov txheej txheem ntau lawm ntawm cov iav fwj.
Cov txheej txheem ntau lawm ntawm iav fwj:
1. Ua ntej ua ntej cov ntaub ntawv raw. Tsoo cov ntaub ntawv nyoos ntau (quartz xuab zeb, soafa tshauv, limestarpar, thiab tshem tawm cov hlau uas muaj cov khoom siv raw kom ntseeg tau tias qhov zoo ntawm lub khob.
2. Batch npaj.
3. Melting. Cov iav batch cov ntaub ntawv yog rhuab ntawm qhov kub siab (1550 ~ 1600 degrees) nyob rau hauv lub pas dej ua kom zoo nkauj los ua cov kua dej ua kom sov uas ua tau raws li cov khoom puab.
4. Kev tsim. Tso cov khob ua kua rau hauv pwm kom ua ib qho khoom lag luam iav uas xav tau. Feem ntau, qhov kev ua si yog tsim ua ntej, thiab tom qab ntawd zaj ua yeeb yam yog tsim rau hauv lub raj mis.
5. Kev kho cua sov. Los ntawm annealing, quenching thiab lwm yam kev ntxhov siab, theem sib cais lossis crystallization ntawm lub khob yog ntxuav lossis tsim tawm, thiab cov qauv ntawm lub khob hloov.
