Tungsten yemhangura
Ruzivo rweChigadzirwa
Matagi eChigadzirwa
Ningbo De-Shin inopa mhando dzakasiyana dzetungsten yemhangura (6~50wt.% Cu) yekushandiswa kwakasiyana-siyana mumaindasitiri. Inotora nzira yepamusoro yekupinda muvacuum uye zvigadzirwa zvese zvinosangana nechiyero cheGB/T 8320-2003, ASTM B 702-93 (Yakabvumidzwazve 2004). Tungsten yemhangura imhando yepseudo-alloy uye ine kugona kwekudzivirira kupfekwa kwetungsten uye conductivity yemagetsi yakawanda yemhangura.
Maitiro ekugadzira:musanganiswa weupfu –> press –> sintering –> vacuum infiltration –> machining –> QC. Maitiro ese ekugadzira aya anodzorwa zvakasimba neQC kuti ive nechokwadi chekuti mashandiro emhando yepamusoro anobudirira.
Zvakanakira:
1. Kudzivirira kwakanyanya kwearc pamwe chete nekufambisa magetsi zvakanaka.
2. Kupisa kwakanyanya.
3. Kuwedzera kwekupisa kushoma.
Mashandisirwo:
1. Kubatanidza ma contacts nema vaccum contacts muma high ne medium voltage breakers kana ma vaccum interruptors.
2. Maerekitirodhi ari mumichina yemagetsi yekucheka kukanganiswa kwezvipenyu.
3. Kuratidzwa Kwechigadzirwa! Kupisa zvinhu zvinotonhodza zvinhu zvemagetsi uye zvekurongedza zvemagetsi.
4. Maerekitirodhi ekushongedza simbi.
Saizi yemasheya:
Tsvimbo yemhangura yetungsten: dhayamita ≥0.5mm; kureba ≤300mm.
Ndiro yemhangura yetungsten: ukobvu ≥1.0mm; kureba & upamhi ≤300mm.
