Kopa Tungsten
Fa'amatalaga Oloa
Faailoga o oloa
Ningbo De-Shin ofo atu se vaega atoa o apamemea tungsten (6 ~ 50wt.% Cu) mo fanua talosaga alamanuia eseese.E manaʻomia le faʻaogaina o le faʻaogaina o masini ma oloa uma e fetaui ma le faʻataʻitaʻiga o GB / T 8320-2003, ASTM B 702-93 (Reapproved 2004).O le tungsten apamemea o le pseudo-alloy ma o loʻo taofiofia le gafatia o le ofuina o le tungsten ma le maualuga o le eletise eletise o le kopa.
Fa'agasologa o gaosiga:fa'afefiloi pa'u -> lolomi -> fa'alumaina -> fa'amama fa'amama -> masini -> QC.O nei gaosiga uma o loʻo faʻatonutonuina e le QC e faʻamautinoa ai le lelei o le faʻatinoga.
Tulaga lelei:
1. maualuga arc tetee tu'ufa'atasia ma lelei conductivity eletise.
2. maualuga conductivity vevela.
3. Faʻalauteleina vevela maualalo.
Talosaga:
1. Fa'apipi'i fa'afeso'ota'i ma fa'afeso'ota'i tui i va'a eletise maualuga ma feololo po'o fa'alavelave tui.
2. Electrodes i afi afi afi tafia masini tipi.
3. Fa'aaliga Oloa!E goto le vevela e avea ma elemene malulu o masini faaeletonika ma mea fa'aeletonika afifiina.
4. Electrodes mo le uelo tetee.
Tele fa'asoa:
La'au tungsten apamemea: diameter≥0.5mm;umi≤300mm.
Kopa tungsten ipu: mafiafia≥1.0mm;umi & width≤300mm.
