Zvikamu zveAlumina Ceramic zveE-Gun Evaporation Systems
St.Cera inogadzira zvinhu zve ceramic zve alumina zvine hutsanana hwakanyanya 99.8% zvakagadzirirwa masisitimu e evaporation e electron beam (E-gun). Zvikamu izvi zvinosanganisira crucible liners, beam deflector shield, insulators, uye mounting fixtures. Zvinhu izvi zvinopa simba re dielectric rakakwirira (15×10⁶ V/m), kugadzikana kwekupisa kusvika 1600°C, uye kuramba kwakanaka kwekupisa uye kurwiswa nemakemikari kubva kuzvinhu zvakapwanyika. Kugona kwedu kugadzira nemazvo kunoita kuti pave ne geometries dzakaoma nehukuru hushoma hwe feature size 0.2mm, flatness 0.003mm, uye surface finish Ra0.1. Chikamu chimwe nechimwe chinoongororwa 100% CMM kuti chionekwe kuti chakarurama.

Mashandisirwo:
- · Magwa emagetsi anopfurwa nepfuti uye magwa anopwanya mvura
- · Zvidzitiro zvekudzivirira danda uye mapurasitiki ekuvhura
- · Zvinodzivirira magetsi uye zvinopa simba
- · Zvishandiso zvekuisa zvinhu zvinobvisa hutsi
Kunyatsogadzira:
Kutwasuka: 0.005mm, kumira kwakatwasuka: 0.005mm, kutenderera: 0.002mm, kumira kwakatwasuka: 0.01mm.
Zvakanakira:
- · Hapana kusvibiswa kwemafirimu matete kubva pazvinhu zvinopiswa
- · Inotsungirira kupisa kwakanyanya panguva yekubuda kwemvura
- · Hupenyu hwebasa hurefu - 5× yakareba kupfuura dzimwe nzira dze graphite
Kugadzirisa:
Maumbirwo emukati memubato wesimbi akagadzirwa nemaoko, maflange ekuisa, mapatani emaburi, uye kupedzisa kwepamusoro zviripo.
