Quartz Diffusion Tube
✔ Kuwongolera moyenera gasi/madzimadzi
✔ Kutumiza{0}} nthunzi wotentha kwambiri
✔ Kugwira ntchito kwamadzimadzi-kusagwira ntchito
✔ Kuphatikiza kwa vacuum system (mpaka 10⁻⁶ Torr)
Kufotokozera
Mawonekedwe
1. Zapamwamba-Zofunika Kwambiri:Opangidwa kuchokera ku 99.999% synthetic fused quartz (SiO₂)
2. Geometry yolondola:M'mimba mwake yunifolomu (± 0.05mm kulolerana) kwa mawonekedwe oyenda osasinthasintha
3. Kukhazikika kwa Matenthedwe:Kupirira ntchito mosalekeza kuchokera -196 digiri mpaka 1100 digiri
4. Kukaniza Chemical:Imalowetsa ku ma acid onse (kupatula HF), zoyambira, ndi zosungunulira organic
5. Kuwonekera Kwambiri:>90% kufala kwa 190nm (UV) kuti 2500nm (IR)
6. Kumaliza Pamwamba:Moto{{0}wopukutira mkati kuti muchepetse kutsata

Ubwino wake
- Kuchita bwino kwambiri kuposa zitsulo zosapanga dzimbiri kapena alumina
- Excellent thermal shock resistance (ΔT >1000 digiri / mphindi)
- Kutsika pang'ono-kutulutsa mpweya pamapulogalamu a UHV
- Sinthani ma geometries ndi kulumikizana
Chitsimikizo chadongosolo
- Chubu chilichonse chimakhala ndi certification ya dimensional
- Kutsimikizira kuyera kwa zinthu (ICP-MS)
- Kuyika kwa Cleanroom kwazinthu zofunika kwambiri

FAQ
Q1: Kodi machubu ophatikizika a quartzwa angagwiritsidwe ntchito ndi hydrofluoric acid?
A: Ayi - quartz imachita mwankhanza ndi HF. Gwiritsani ntchito njira zina za fluoropolymer m'malo mwake
Q2: Ndi zovuta ziti zomwe angapirire?
A: Machubu okhazikika adavotera 3 bar
Q3: Kodi chubu cha quartz diffusion chikuyerekeza bwanji ndi ceramic pamatenthedwe apamwamba-?
A: Quartz imapereka:
- Kulimbana bwino ndi kutentha kwa kutentha
- Kuyeretsedwa kwamankhwala kwapamwamba
- Kuwonekera kwa kuwala
- Kumaliza kosalala
Q4: Ndi maulumikizi ati omwe alipo?
A: Zosankha zikuphatikizapo:
- Malumikizidwe opindika
- Magalasi apansi
- Makanema
- Chitsulo mwamakonda-ku-zosindikizira za quartz
