FAQ
Q: Koj puas tuaj yeem kho quartz flange?
A: Yog, peb tuaj yeem ua tau. Peb tuaj yeem kho koj qhov loj me raws li koj xav tau.
Q: Lub siab siab npaum li cas tuaj yeem quartz flange tiv taus?
A: Muaj feem xyuam rau 10⁻⁹ mbar ultra- lub tshuab nqus tsev siab, flange thickness yuav tsum tau hloov kho raws li qhov loj me (xws li DN100 flange pom zoo kom ntau dua lossis sib npaug li 20mm ntawm 10⁻⁶ mbar).
- Daim ntawv thov siab zoo: Cov kev ua haujlwm siab 0.5 ~ 1 MPa (nyob ntawm tus qauv), kev ntxhov siab hauv zos yuav tsum zam.
Q: Dab tsi yog qhov kev txwv machining ntawm quartz flanges?
A: - Kev pheej hmoo ntawm brittleness: Mohs hardness 7, tab sis tsis zoo cuam tshuam, drilling / txiav yuav tsum tau laser lossis pob zeb diamond cuab yeej kom tsis txhob muaj kev ntxhov siab.
- Precision yuav tsum: Flatness yuav tsum tsawg dua los yog sib npaug rau 0.02mm, nto roughness Ra tsawg dua los yog sib npaug rau 0.1μm los xyuas kom meej sealing.
