Tungsten ea Silevera
Qaqiso ea Sehlahisoa
Li-tag tsa Sehlahisoa
Ningbo De-Shin e fana ka mefuta e felletseng ea tungsten ea silevera 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/T8320-2003, ASTM B631.
Tshebetso ea tlhahiso:motsoako oa phofo –> ho tobetsa –> ho sintering –> ho kenella ha vacuum –> ho sebetsa –> QC. Ts'ebetso ena eohle ea tlhahiso e laoloa ka thata ke QC ho netefatsa ts'ebetso ea boleng bo holimo.
Melemo:
1. Ho tsamaisa motlakase ka lebelo le phahameng.
2. Ho khanna mocheso o phahameng.
3. Boima bo phahameng ka ho lekana ho phethahetseng ha thepa e nyane.
Likopo:
1. Di-circuit breaker.
2. Dithunya tsa ho dutla ha lefatshe.
3. Di-breaker tse nyane tsa potoloho.
4. electrode ea ho tjheseletsa ea khanyetso.
5. moqomo o hanyetsang ho roala
Boholo ba setoko:
Thupa ea tungsten ea silevera: bophara ba ≥0.5mm, hangata 1-60mm; bolelele ba ≤300mm, hangata 100, 175, 200, 300mm.
Sekwere sa tungsten sa silevera: botenya≥1.0mm, hangata 1-40mm; bolelele le bophara≤400mm, hangata 100*200, 200*300, 200*400mm.
