Ufa wa silika, monga ufa wabwino kwambiri, wakhala chinthu chofunikira kwambiri m'makampani amakono chifukwa cha mphamvu zake zapadera zakuthupi ndi zamakemikolo komanso malo ogwiritsidwa ntchito kwambiri. Nkhaniyi ifotokoza za makhalidwe, njira zopangira, ndi momwe ufa wa silika umagwiritsidwira ntchito mwatsatanetsatane, ndikuyang'ana kwambirimakina opukusira a silika okhala ndi ma mesh 600 ultrafine .
Chiyambi cha Ufa wa Silika
Ufa wa silicon umapangidwa makamaka ndi silicon. Ndi ufa watsopano wosagwira ntchito wachitsulo, womwe umapezeka posankha kristalo wachilengedwe wosakanikirana kapena quartz wosakanikirana ngati zopangira ndi kukonzedwa mozama kudzera m'njira zosiyanasiyana. Gawo lake lalikulu ndi silicon dioxide, ndipo kapangidwe ka kristalo kakhoza kukhala m'njira zosiyanasiyana monga cubic, hexagonal ndi orthorhombic. Kukula kwa tinthu ta silicon powder nthawi zambiri kumakhala pakati pa nanometers ochepa ndi ma microns makumi. Malinga ndi kukula kwa tinthu, tingagawidwe m'ma nano silicon powder ndi micro silicon powder.
Ufa wa silika uli ndi mphamvu zabwino zoletsa kugwiritsa ntchito mankhwala komanso zinthu zakuthupi, monga kukana asidi ndi alkali, kukana okosijeni/kuchepetsa, kukana kupopera mchere ndi kukhazikika kwa electrochemical, kuuma kwambiri, kukhazikika kwa kutentha kwambiri, kutchinjiriza kwambiri, kukulitsa pang'ono, kukana kukhudza kuwala kwa UV, ndi zina zotero. Zinthu zabwino kwambirizi zimapangitsa kuti ufa wa silika ukhale ndi mwayi wogwiritsidwa ntchito m'magawo ambiri.
Kugwiritsa ntchito ufa wa silicon kumapeto
Makampani opanga mphira ndi pulasitiki: Ufa wa silika ukhoza kuwonjezera kuuma, mphamvu, kukana kuwonongeka ndi kukana kukalamba kwa mphira ndi pulasitiki, komanso ukhozanso kuwonjezera kukana kutentha, kukana kuzizira komanso kukana UV, pomwe umagwira ntchito ngati chodzaza kuti uchepetse ndalama.
Makampani Opaka Utoto: Ufa wa silika ukhoza kuwonjezera kuuma, kunyezimira komanso kukana kukalamba kwa utoto ndikuletsa utoto kuti usasweke ndi kusweka.
Makampani a zamagetsi: Ufa wa silicon ungagwiritsidwe ntchito pokonza zipangizo za semiconductor, ulusi wa kuwala, mafilimu a kuwala, ma capacitor, mabatire, maselo a dzuwa ndi zida zina zamagetsi.
Makampani Ogulitsa Zodzoladzola: Ufa wa silika ungagwiritsidwe ntchito ngati chodzaza mu zodzoladzola kuti uwonjezere kapangidwe ndi kusinthasintha, kukulitsa kuwonekera bwino komanso kunyezimira, ndipo umagwiritsidwa ntchito popanga zodzoladzola zoteteza ku dzuwa, zodzoladzola, zotsukira nkhope, ndi zina zotero.
Kuphatikiza apo, ufa wa silicon micropowder umagwiritsidwanso ntchito kwambiri mu galasi, zoumba, mankhwala abwino, zipangizo zamakono zomangira ndi zina. Makamaka mu epoxy molding compounds, ufa wa silicon micropowder umagwira ntchito ngati chodzaza chofunikira kuti uchepetse linear expansion coefficient, kuwonjezera kutentha kwa mpweya, ndikuchepetsa dielectric constant.
Njira yopangira silicon micropowder
Njira yopangira ufa wa silika ndi yovuta komanso yofewa kuti iwonetsetse kuti ukhondo wake, kukula kwa tinthu tating'onoting'ono ndi mtundu wake ndi woyenera kukwaniritsa zofunikira zamitundu yosiyanasiyana yogwiritsira ntchito. Njira zazikulu zopangira zimaphatikizapo kuphwanya kolimba, kuchotsa zodetsa, kupukuta bwino ndi kugawa m'magulu.
Kuphwanya koopsa: Zidutswa zazikulu za mchere wa quartz ziyenera kuphwanyidwa kaye ndi chotsukira nsagwada kuti zichepetse kukula kwa tinthu tating'onoting'ono ta miyala yoyambirira kuti ikonzedwenso pambuyo pake.
Kuchotsa zodetsa: Zodetsa zomwe zili mu miyala zimachotsedwa pogwiritsa ntchito njira zakuthupi komanso zamankhwala monga kusankha mitundu, kuyandama, ndi kulekanitsa zinthu pogwiritsa ntchito maginito. Kuchotsa zodetsa zazing'ono kumaphatikizaponso kusakaniza ndi kusakaniza ndi calcining. Kusakaniza kumatha kuchotsa zodetsa za ayoni zachitsulo, pomwe kusakaniza ndi calcination kumachotsa zodetsa za lattice kudzera mu sintering.
Kupera bwino: Kugwiritsa ntchitoa Chopukusira cha silicon micropowder ultrafine chokhala ndi ma mesh 600kupukutira kuti zikwaniritse zofunikira za kukula kwa tinthu toyenera.
Kugawa: Ufa wa silikoni wophwanyidwa bwino uyenera kugawidwa m'magulu malinga ndi kayendedwe ka mpweya kuti zitsimikizire kuti kufalikira kwa tinthu tating'onoting'ono kukukwaniritsa zofunikira.
Makina oyambira opukutira a silicon ufa wa ultrafine 600 mesh
Makina opukusira a silicon micro powder ultrafine okhala ndi ma mesh 600, mongaGuilin Hongcheng HCH chitsanzo cha ultrafine ring roller grinding machinendiHLMX mndandanda wa ultrafine vertical mill, ndi zida zogwira mtima kwambiri zomwe zimapangidwira kukonza ufa wa silicon micro wa maukonde 600. Zipangizozi zimagwiritsa ntchito ukadaulo wapamwamba wopera ndipo zimatha kupanga mosalekeza ufa wa silicon micro wa maukonde 325-2500 (45um-7um).
Kupyolera mu kuphwanya, kupukuta, kugawa m'magulu ndi njira zina, kufalikira kwa tinthu tating'onoting'ono ta ufa wa silicon micro kumatsimikizika kuti kukwaniritse zofunikira zosiyanasiyana zogwiritsidwa ntchito kwambiri.
Guilin Hongcheng ndi katswiri pa mitundu yosiyanasiyana ya zida zopukutira ndipo amapatsa makasitomala njira zonse zopangira ufa. Makina opukutira a silicon micropowder ultrafine okhala ndi ma mesh 600 amagwiritsa ntchito njira yotsekedwa, yomwe ndi yokhazikika komanso yodalirika kuyambira, yokhala ndi phokoso lochepa komanso fumbi lochepa, yosunga mphamvu zodziwikiratu komanso yochepetsa kugwiritsa ntchito, kugawa tinthu tating'onoting'ono ta zinthu zomalizidwa, kusinthasintha pang'ono, kuyera kwambiri komanso khalidwe lokhazikika.
Guilin HongchengMakina opukusira a silicon micropowder ultrafine 600 meshyalimbikitsa kugwiritsa ntchito ufa wa silicon m'magawo osiyanasiyana chifukwa cha magwiridwe ake ogwira ntchito bwino komanso okhazikika, komanso yalimbikitsa chitukuko ndi luso la mafakitale ena ofanana. Kuti mudziwe zambiri za mphero yopera kapena pempho la mtengo chonde titumizireni uthenga.
