Anthu akamamva mawu akuti White Fused Alumina Micropowder, anthu ambiri omwe si a makampani opanga zinthu zonyasa angaone kuti ndi zachilendo. Komabe ufa woyera wabwinowu umagwira ntchito pang'onopang'ono m'mbali zambiri za moyo watsiku ndi tsiku—kuyambira pazenera za mafoni ndi magalasi a maso mpaka zida zamagalimoto ndi zida zamlengalenga. Monga chonyasa chopangidwa ndi zinthu zoyera komanso zolimba kwambiri, ufa woyera wosakanikirana wa alumina micropowder umayamikiridwa chifukwa cha njira yake yopangira yolondola komanso ntchito zosiyanasiyana zamafakitale.
Kuchokera ku Zipangizo Zopangira Kupita ku Ufa Waufupi: Njira Yopangira Yokhwima
Ambiri amaganiza kuti ufa wa micropowder umangopangidwa pophwanya tinthu ta alumina toyera tomwe timasakanikirana, koma zoona zake n’zovuta kwambiri.
1. Kusankha Zinthu Zopangira ndi Kusamalira Zinthu Pasadakhale
Ufa wa alumina woyera wopangidwa bwino kwambiri umayamba ndi ufa wa alumina wa mafakitale wapamwamba kwambiri, wokhala ndi chiyero cha Al₂O₃ choposa 99.5%. Zipangizo zoyera pang'ono zimatha kusokoneza kuuma, kuyera, komanso kukhazikika kwa mankhwala. Ufa wosaphika usanasungunulidwe, umafufuzidwa ndikuyikidwa m'magulu a mpweya kuti uchotse tinthu tating'onoting'ono ndikuwonetsetsa kuti tinthu tating'onoting'ono timeneti timakhala tofanana kuti tisungunuke bwino.
2. Kusungunula ndi Kukonza Ng'anjo ya Arc yamagetsi
Ufa wa alumina wokonzedwa kale umasungunuka mu uvuni wamagetsi wa magawo atatu pa kutentha kwa 2050–2150°C kwa maola 4–6. Pa kutentha kwakukulu kumeneku, alumina imasungunuka kwathunthu kukhala madzi, pomwe zinyalala zimapatukana ndikukhazikika chifukwa cha kusiyana kwa kuchulukana.
Kulamulira kutentha n'kofunika kwambiri panthawiyi. Ma electrode amaikidwa mkati mwa dziwe losungunuka kuti atsimikizire kuti kutentha kuli kofanana. Pakuzizira, kuzizira mwachangu kumayikidwa pa kutentha kwakukulu, kutsatiridwa ndi kuzizira pang'onopang'ono pa kutentha kochepa, zomwe zimapangitsa kuti makhiristo okhazikika a α-Al₂O₃ apangidwe. Akazizira, zinthuzo zimauma kukhala zipolopolo zoyera zosakanikirana za alumina zokhala ndi kuuma komanso kulimba kwambiri.
3. Kuphwanya, Kupera, ndi Kugawa Molondola
Mabuloko a alumina osakanikirana amayamba kuphwanyidwa ndi zitsulo zophwanyira nsagwada, kenako amachepetsedwa bwino ndi ma roller mill, kenako amakonzedwa kukhala ufa wa micron-scale pogwiritsa ntchito ma jet mill.
Kuti tikwaniritse kugawa kwa tinthu tomwe timapanga tinthu tating'onoting'ono molondola, njira zamakono zopangira ma hydraulic overflow ndi njira zopangira ma air-flow zimagwiritsidwa ntchito kulekanitsa ma grade osiyanasiyana monga W5, W10, ndi W20, ndipo zinthu zina zimafika pamlingo wa submicron.
Pambuyo poika m'magulu, ufawo umatsukidwa ndi asidi, kutsukidwa ndi madzi, kuumitsa, ndi kulekanitsidwa ndi maginito kuti uchotse chitsulo chotsalira, sodium, ndi zina zodetsa. Kuwunika komaliza kwa khalidwe kumaphatikizapo kufufuza kwa microscopic ndi kusanthula kukula kwa tinthu tisanayambe kulongedza.
Kugwiritsa Ntchito Kofunika Kwambiri kwa White Fused Alumina Micropowder
Chifukwa cha kuuma kwake kwakukulu, kuyera kwake kwakukulu, komanso kukhazikika kwa mankhwala, ufa woyera wosakanikirana wa alumina umagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana.
Kupera ndi Kupukuta Mwanzeru
Iyi ndi imodzi mwa ntchito zofunika kwambiri. Zinthu monga magalasi owoneka bwino, mapanelo a LCD, ndi ma wafer a semiconductor zimafuna malo osalala komanso olondola kwambiri.
Ndi kuuma kwa Mohs kwa 9—kwachiwiri kuposa diamondi—ufa woyera wosakanikirana wa alumina umapereka tinthu tating'onoting'ono tomwe timapukuta bwino popanda kukanda pamwamba.
Kawirikawiri amagwiritsidwa ntchito pa:
- Mafoni a Sapphire
- Magalasi a maso
- Masamba a injini zamagalimoto
- Ma berea olondola
- Zipangizo zachipatala
Mankhwala ambiri opukutira ndi zinthu zina zopukutira pogwiritsa ntchito ufa woyera wosakanikirana wa alumina amagwiritsidwanso ntchito ngati chinthu chofunikira kwambiri.
Kupanga Zida Zolimba Kwambiri
Ufa woyera wa alumina wosakanikirana umagwiritsidwa ntchito popanga:
- Mawilo opukutira opangidwa ndi utomoni
- Mawilo opukutira a Ceramic
- Ma disc odulira opyapyala kwambiri
- Ma sandpaper apamwamba komanso malamba okulungira
Zipangizozi zimakhala zakuthwa kwambiri, zimapangitsa kuti kutentha kuchepe, komanso zimakhala ndi nthawi yayitali yogwirira ntchito, zomwe zimapangitsa kuti zikhale zabwino kwambiri popera chitsulo chosapanga dzimbiri, zitsulo zolimba, zoumba, ndi malo amatabwa.
Zipangizo Zopumira ndi Zodzaza Zamakampani
Ndi kutentha kopitirira 2200°C komanso kukana kutentha, asidi, ndi alkali, ufa woyera wa alumina wosakanikirana ndi chinthu chabwino kwambiri chopangira zinthu zapamwamba zotsutsa.
Amagwiritsidwa ntchito kwambiri mu:
- Zingwe zachitsulo za ng'anjo
- Zipinda zagalasi zophikira ng'anjo
- Zophimba zosatha kuvala
- Zipangizo zolimbitsa za Ceramic
- Zipangizo zamagetsi zophikira zotetezera kutentha ndi kuyeretsa kutentha
Tsogolo la White Fused Alumina Micropowder
Ngakhale kuti ikuwoneka ngati ufa wamba woyera, ufa woyera wosakanikirana wa alumina micropowder ndi zotsatira za njira yopangira yokhwima komanso yotsogola. Kuyambira kusankha zinthu zopangira mpaka kulongedza komaliza, sitepe iliyonse imafuna kuwongolera kolondola kuti zitsimikizire kuti ndi yoyera kwambiri komanso yogwira ntchito nthawi zonse.
Pamene mafakitale monga kupanga zinthu molunjika, zamagetsi, kuwala, ndi ma semiconductor akupitirira kukula, kufunikira kwa zipangizo zapamwamba kwambiri kudzangowonjezeka. M'tsogolomu, ufa woyera wosakanikirana wa alumina udzakhala ndi gawo lalikulu kwambiri pa ntchito zapamwamba komanso zokonzedwa bwino zamafakitale.
Monga "katswiri wosaoneka bwino wopukuta," ufa woyera wa alumina wosakanikirana ukupitirizabe kupanga dziko lamakono—malo osalala nthawi imodzi.
