Chenjezo logwiritsa ntchito zinthu za tungsten ndi molybdenum

1. Kusungirako

Zogulitsa za Tungsten ndi molybdenum ndizosavuta kutulutsa ndikusintha mtundu, motero ziyenera kusungidwa m'malo okhala ndi chinyezi chochepera 60%, kutentha kosachepera 28 ° C, komanso kulekanitsidwa ndi mankhwala ena.
Ma oxide a tungsten ndi zinthu za molybdenum amasungunuka m'madzi ndipo ndi acidic, chonde mverani!

2. Kuipitsa embrittlement

(1) Pa kutentha kwakukulu (pafupi ndi malo osungunuka a zitsulo), imakhudzidwa ndi zitsulo zina (chitsulo ndi ma alloys ake, nickel ndi ma alloys ake, etc.), nthawi zina zimapangitsa kuti zinthuzo ziwonongeke.Pochita kutentha kwa tungsten ndi mankhwala a molybdenum, chidwi chiyenera kulipidwa!
Chithandizo cha kutentha chiyenera kuchitidwa mu vacuum (pansi pa 10-3Pa), kuchepetsa (H2) kapena mpweya wa inert (N2, Ar, etc.) mpweya.
(2) Zinthu za Tungsten ndi molybdenum zimakhazikika zikachita ndi kaboni, choncho musawakhudze pamene chithandizo cha kutentha chikuchitidwa pa kutentha pamwamba pa 800 ° C.Koma mankhwala molybdenum pansipa 1500 ℃, mlingo wa embrittlement chifukwa carbonization ndi laling'ono kwambiri.

3. Machining

(1) Kupinda, kukhomerera, kumeta ubweya, kudula, ndi zina zotero za mbale za tungsten-molybdenum zimakhala zosavuta kung'amba pamene zimakonzedwa ndi kutentha, ndipo ziyenera kutenthedwa.Panthawi imodzimodziyo, chifukwa cha kusakaniza kosayenera, nthawi zina delamination imapezeka, kotero kutentha kumalimbikitsidwa.
(2) Komabe, mbale ya molybdenum idzakhala yowonongeka ikatenthedwa pamwamba pa 1000 ° C, zomwe zidzachititsa kuti zikhale zovuta pokonza, choncho tcheru chiyenera kulipidwa.
(3) Pamene makina akupera tungsten ndi molybdenum mankhwala, m'pofunika kusankha njira akupera yoyenera zochitika zosiyanasiyana.

4. Njira yochotsera okosijeni

(1) Tungsten ndi molybdenum mankhwala ndi zosavuta oxidize.Pamene ma oxides olemera akufunika kuchotsedwa, chonde perekani kampani yathu kapena perekani ndi asidi amphamvu (hydrofluoric acid, nitric acid, hydrochloric acid, etc.), chonde mverani mukamagwira ntchito.
(2) Pa ma oxide ofatsa, gwiritsani ntchito chotsukira ndi zomatira, pukutani ndi nsalu yofewa kapena siponji, ndiyeno muzimutsuka ndi madzi ofunda.
(3) Chonde dziwani kuti zitsulo zonyezimira zidzatayika mutatsuka.

5. Njira zopewera kugwiritsa ntchito

(1) Pepala la tungsten-molybdenum ndi lakuthwa ngati mpeni, ndipo zoboola pamakona ndi kumapeto zimatha kudula manja.Mukamagwiritsa ntchito mankhwalawa, chonde valani zida zodzitetezera.
(2) Kuchulukitsitsa kwa tungsten kumakhala pafupifupi kuwirikiza ka 2.5 kuposa chitsulo, ndipo kuchulukira kwa molybdenum kumakhala pafupifupi kuwirikiza ka 1.3 kuposa chitsulo.Kulemera kwenikweni ndi kolemera kwambiri kuposa maonekedwe, kotero kugwira ntchito pamanja kungapweteke anthu.Ndi bwino kuchita ntchito Buku pamene kulemera ndi pansipa 20KG.

6. Kusamala posamalira

Zogulitsa za tungsten ndi molybdenum za opanga mbale za molybdenum ndi zitsulo zowonongeka, zomwe zimakonda kusweka ndi delamination;Choncho, ponyamula, samalani kuti musagwiritse ntchito kugwedezeka ndi kugwedezeka, monga kugwa.Komanso, ponyamula katundu, chonde lembani ndi zinthu zomwe zimasokoneza mantha.
