Tungsten ea Koporo
Qaqiso ea Sehlahisoa
Li-tag tsa Sehlahisoa
Ningbo De-Shin e fana ka mefuta e felletseng ea tungsten ea koporo (6~50wt.% Cu) bakeng sa masimo a fapaneng a ts'ebeliso ea indasteri. E nka ts'ebetso e tsoetseng pele ea ho kenella ka vacuum 'me lihlahisoa tsohle li fihlela tekanyetso ea GB/T 8320-2003, ASTM B 702-93 (E Amohetsoe Bocha ka 2004). Tungsten ea koporo ke motsoako oa pseudo 'me e na le bokhoni ba ho hanyetsa ho tsofala ha tungsten le motlakase o phahameng oa koporo.
Tshebetso ea tlhahiso:motsoako oa phofo –> tobetsa –> sintering –> ho kenella ha vacuum –> machining –> QC. Ts'ebetso ena eohle ea tlhahiso e laoloa ka thata ke QC ho netefatsa ts'ebetso ea boleng bo holimo.
Melemo:
1. Khanyetso e phahameng ea arc e kopantsoeng le conductivity e ntle ea motlakase.
2. Ho khanna mocheso o phahameng.
3. Katoloso e tlase ea mocheso.
Likopo:
1. Ho kopanya likhokahano le likhokahano tsa vaccum ka har'a li-breaker tsa motlakase o phahameng le o mahareng kapa li-interruptor tsa vaccum.
2. Li-electrode tse mechineng ea motlakase ea ho seha khoholeho ea tlhase.
3. Pontšo ea Sehlahisoa! Li-heat sinks e le likarolo tse pholileng tse sa sebetseng tsa lisebelisoa tsa elektroniki le thepa ea ho paka ea elektroniki.
4. Li-electrode tsa ho tjheseletsa ho hanyetsa.
Boholo ba setoko:
Thupa ea koporo ea tungsten: bophara≥0.5mm; bolelele≤300mm.
Poleiti ea koporo ea tungsten: botenya≥1.0mm; bolelele le bophara≤300mm.
