(WntrustekAmatulutsa zonse ziwiriAlubinandiMullite)

Lumina ceramic, nthawi zina amatanthauzaAluminium oxide (Al2o3) or alubina, ndi mlingo wa mafakitale osungirako mafakitale omwe amachititsa mphamvu kwambiri komanso olimba kwambiri. Chifukwa cha mikhalidwe yawo,alumina ceramicsndi ena mwa cideria odziwika kwambiri chifukwa cha kuwonongeka, kuvala, ndi makina. Nthawi zambiri opangidwa kuchokera ku bauxite, alumina ceremics atha kuumbidwa ndi powonjezera, jakisoni, amafa, ndikukakamiza, ndikuponyera diamondi.

Mulliteimapangidwa ndi opukuta silika ndi alumina osiyanasiyana panthawi yochimwa, kupanga zida zosiyanasiyana. Kwa zolimba zolimba, zimatchedwa Mullite; Kwa maphunziro amphamvu, imatchedwa kuti ululu kapena kunyowa.

Pali mitundu iwiri ya mankhwalawa (al2o3-sio2): mafomu opweteka komanso osalala. Mphamvu yayikulu ndi kukana kwapadera pakuwotcha kugwedezeka zimaphatikizidwa mu modzimalumwa kwambiri (wopanda mphamvu) mullite. Kukula kwamphamvu kwa mullrous mullmal komanso mphamvu yayikulu kumapereka milingo yosinthika yamafuta.

Mullite Ceramicsamalemba ntchito m'magetsi, timasula, mafupa, ndi kuvala komanso kuwonongeka kwa miyala yamtengo wapatali chifukwa cha kutentha kwawo kwamiyala ndi kutentha kwa makondo a 2910F (1600).

Katundu wofunikiraAlubina:

• Kukhazikika kwa kutentha

• Kulimba kwambiri komanso kuuma

• Kutulutsa kwamagetsi

• Kukana mwaluso kwambiri kuvala ndi kukangana

• Kutha kulimbana ndi chithokomiro patenthedwe

Katundu wofunikiraMullite:

• Kukhazikika pamatenthedwe kwambiri

• Kukana mankhwala

• Kukula kochepa kwa kutentha

• Mphamvu ya makina

• Kukopa kwa Makina Osiyanasiyana

Kapangidwe ndi kapangidwe kake

Aluminium oxide (Al2o3)Ndi zoyera kuyambira 75% mpaka kupitirira 99% ndiye mankhwala akulu omwe amagwiritsidwa ntchito popanga alumina craramics. Kuuma ndikuvala kuvala kuchuluka kwa alumina kukhazikika. Kapangidwe kalikonse kamapereka chodalirika komanso mphamvu yamakina.

Zinthu zomwe zimapangaMullite Ceramicsndi aluminium slika (3lo3·2SiO2). Nthawi zambiri amapangidwa ndi kutentha kwambiri kwa silika ndi alumuna, omwe amatulutsa mawonekedwe owoneka bwino ndi kukhazikika kwamitundu yapamwamba. Kukhazikika kwa mullite kwa kugwedeza kwa mafuta amphamvu komanso kuwonjezeka kwa mafuta ochepa kumapangitsa kuti zikhale zofunikira kwambiri.

Katundu wathupi

AlubinaKutsutsana kwakukulu kwa Abrasion kumapangitsa kuti ikhale yabwino kudula zida ndi zokutira zoteteza.

Mullite's ndi mphamvu zapadera komanso mphamvu (6-7 mohs (6-7 mohs) zimapangitsa kuti ikhale chisankho chabwino pa ndege ndi zingwe zokana.

Makina

AlubinaAmadziwika bwino chifukwa cha kulimba kowoneka bwino, mphamvu zapamwamba kwambiri, komanso kupambana kwakukulu. Makhalidwe amenewa amasankha bwino kuvala mzere, kupera makanema, ndi ntchito zapamwamba zomwe abrasion ndi nkhawa yayikulu.

Mullitendizovuta kuposa alumina, komabe zimapereka mphamvu yokwanira pomweponso ikutsika. Khalidwe lake lamakina limakhala bwino chifukwa chokhoza kusintha kutentha kwambiri.

Mafuta ndi Kugwiritsa Ntchito Mafuta

Alumina ceramicsamatha kukana kwambiri kutentha kwambiri pomwe pokhala ndi zowoneka bwino kwambiri. Amakhalanso osagwirizana kwambiri ndi asidi ndi alkalis, ndikuwapangitsa kukhala bwino pazovuta zamankhwala.

MulliteCeramics imayima mokwanira magetsi owopsa komanso kuchuluka kwamphamvu. Amagwira ntchito bwino m'magulu apamwamba, ma kilo azingwe, komanso ntchito zosintha zomwe makonda amapezeka pafupipafupi.

Ntchito:

AlubinaMakhalidwe opatsa mphamvu amapangitsa kuti ikhale yoyenera yamagetsi ndi zida zamagetsi. Chifukwa chatsani mphamvu zakumwa, alumini ceremics nthawi zambiri amagwiritsidwa ntchito pogaya mipira, kuvala zozinga, ndi mapaipi omwe moyo wautumiki umafunikira.

MulliteKukhazikika kwa kutentha ndikofunikira kuti zikhale zosinthana ndi zingwe zophatikizira.

Kuti,alumina ceramicsndi zinthu zosankhidwa zokhala ndi zoopsa zapamwamba komanso zovulaza chifukwa cha zovuta zapamwamba, kubvundikirani, ndi kusintha kwamankhwala.Mullite ceramicsKomabe, kumbali ina, kukhala ndi kukhazikika kwapamwamba kwambiri ndikukumana ndi kutentha kwa kutentha msanga, kuwapangitsa kukhala oyenera ntchito zamagetsi ambiri.
