I-Copper Tungsten
Iinkcukacha zeMveliso
Iithegi zeMveliso
I-Ningbo De-Shin inikezela ngoluhlu olupheleleyo lwe-tungsten yobhedu (6~50wt.% Cu) kwiindawo ezahlukeneyo zokusetyenziswa kwemizi-mveliso. Ithatha inkqubo yokungena kwe-vacuum ephucukileyo kwaye zonke iimveliso ziyahlangabezana nomgangatho we-GB/T 8320-2003, ASTM B 702-93 (Ivunyiwe kwakhona ngo-2004). I-tungsten yobhedu yi-pseudo-alloy kwaye inamandla okumelana nokuguguleka kwe-tungsten kunye nombane ophezulu we-copper.
Inkqubo yemveliso:umxube wepowder –> cinezela –> ukucocwa –> ukungena kwevacuum –> umatshini wokwenza isinyithi –> QC. Yonke le nkqubo yemveliso ilawulwa ngokungqongqo yi-QC ukuqinisekisa ukusebenza okusemgangathweni ophezulu.
Iingenelo:
1. Ukumelana okuphezulu kwe-arc kunye nokuqhuba kakuhle kombane.
2. Ukuqhuba okuphezulu kobushushu.
3. Ukwanda okuphantsi kobushushu.
Izicelo:
1. Ukudibanisa ii-arcum contacts kunye nee-vaccum contacts kwii-high and medium voltage breakers okanye ii-vaccum interruptors.
2. Ii-electrode kwiimatshini zokusika ukhukuliseko lwentlantsi zombane.
3. Umboniso weMveliso! Izinki zobushushu njengezinto zokupholisa ezingasebenziyo zezixhobo ze-elektroniki kunye nezixhobo zokupakisha ze-elektroniki.
4. Ii-electrode zokuwelda ukuxhathisa.
Ubungakanani besitokhwe:
Intonga ye-tungsten yobhedu: ububanzi≥0.5mm; ubude≤300mm.
Ipleyiti ye-tungsten yobhedu: ubukhulu ≥1.0mm; ubude kunye nobubanzi ≤300mm.
