Fused quartz cov ntaub ntawv nyob rau hauv peev casting plhaub nyob rau hauv cov teb chaws tsim tau nce xyoo los ntawm lub xyoo, tshwj xeeb tshaj yog nyob rau hauv silica sol pwm plhaub ntawm nto txheej muaj ntau yam kev.Sib piv nrog tus nqi thiab kev siv cov khoom siv zirconium tau ua tiav zoo, Nws yog qhov zoo tshaj plaws engineering daim ntawv thov cov ntaub ntawv tam sim no.
Fused quartz khoom raug xaiv zoo silica raw cov ntaub ntawv [sio2> 99%], melting nyob rau hauv arc rauv los yog tsis kam rauv, ntawm qhov kub ntawm 1695-1720 ℃.Vim lub siab viscosity ntawm sio2 yaj, uas yog 10 ^ 7 Pa·s ntawm 1900 ℃, nws tsis tuaj yeem molded los ntawm txoj kev casting.Tom qab txias, nws yog vitreous thiab tuaj yeem siv los ua raw khoom rau cov khoom raug rho tawm lossis tsis raug rho tawm haujlwm.Lub Fused silica yog tus cwj pwm los ntawm kev ua haujlwm zoo thermal poob siab, tsis tshua muaj thermal conductivity, me me expansion coefficient, kub tsis kam nyob rau hauv cov khoom ceramic thiab cov ntaub ntawv refractory.Yog li nws muaj thermal stability heev.Yog li ntawd, nyob rau hauv tus txheej txheem ntawm roasting thiab pouring molten quartz plhaub tsis tshua tawg vim khaus kub, Nws yog ib qho zoo tagnrho cov ntaub ntawv nyob rau hauv peev casting molding refractory, kuj yuav siv tau raws li nto txheej los yog rov qab txheej txheej refractory ntaub ntawv.
Peb cov khoom siv Fused silica feem ntau yog siv hauv precision casting, quartz ceramic roller hauv iav kev lag luam, cov ntaub ntawv refractory, ceramic raw khoom, iav raw cov ntaub ntawv, epoxy resin casting, hluav taws xob sealing cov ntaub ntawv, hluav taws xob lub teeb qhov chaw, kev kho mob, casting, thiab lwm yam lag luam ntawm lub cov ntaub ntawv tseem ceeb, thiab tseem nyob rau hauv cov xim, txheej thiab lwm yam kev lag luam tshuaj zoo tagnrho filling khoom.
Cov ntsiab lus ntawm Sio2 purity rau fused quartz: Sio2 cov ntsiab lus ntawm Fused silica qib A yuav tsum tsis pub tsawg dua 99.95%, qib B yuav tsum tsis pub tsawg dua 99.8%, thiab qib C yuav tsum tsis pub tsawg dua 99%.
