Aluminiyamu Oxide Crucible AL2O3 Crucible
ulaliki wazinthu
Aluminium oxide crucible yomwe imadziwika kuti corundum crucible, anthu nthawi zambiri amakhala ndi aluminiyamu mu 95% crucible yotchedwa corundum crucible.Corundum crucible ndi kukana kusungunuka kwamphamvu, kukana kutentha kwambiri, kukana kwa asidi ndi alkali, kuzizira komanso kukana kutentha, kukana kwa dzimbiri.Ndizoyenera kuzinthu zina zamchere zofooka monga anhydrous Na2CO3 monga zitsanzo zosungunuka, koma osati za Na2O2, NaOH, ndi zina. kutchinjiriza ndi mphamvu zamakina mu redox mlengalenga wa 1650 ℃ -1700 ℃, ndi kutentha kwakukulu kwa 1800 ℃ munthawi yochepa.Malinga ndi momwe amagwiritsidwira ntchito, ma alumina crucibles amapezeka mosiyanasiyana komanso mawonekedwe.
Main Features
Zazikulu za alumina ceramic crucible: kutentha kukana kwa madigiri pafupifupi 1200, oyenera K2S207 ndi zitsanzo zina zosungunuka za asidi.Nthawi zambiri, sayenera kugwiritsidwa ntchito kusungunula Na0H, Na202 ndi Na2CO3, kuti asawononge zadothi crucible.Porcelain crucible sangathe kukhudzana ndi hydrofluoric acid.
Alumina ceramic crucible akhoza yophika HCl kuonetsetsa chiyero cha zinthu ndi mkulu kutentha kukana.Zinthuzo zimakhala ndi kachulukidwe wapamwamba, kukana kwa okosijeni wabwino, madigiri 400-500 apamwamba kuposa ma graphite, mpaka madigiri 900 apamwamba, moyo wautali wautumiki.Ndi kukana kutentha kwakukulu, kutsika kwamafuta owonjezera kutentha, kutentha kwabwino komanso kukana kugwedezeka komanso kukana kwa dzimbiri.Kuchita kwa mankhwala kumakhala kokhazikika ndipo kwenikweni sikumayenderana ndi chitsulo chosungunuka, kumapangitsa chiyero cha alloy.
(1) N’zosavuta kuchapa komanso kukhala aukhondo.Kuwala kwa ceramic crucible ndikowala komanso kosavuta, ndipo ndikosavuta kutsuka mukatha kugwiritsa ntchito.
(2) Porcelain stoma ndi yochepa kwambiri, ndipo mayamwidwe amadzi ndi otsika kwambiri.Kusungirako yankho ndi ceramic crucible ndi kusindikiza mwamphamvu kungalepheretse kuphulika, kulowetsedwa ndi kuwukira kwa mabakiteriya akunja.
(3) Kukhazikika kwa Chemical ndi kukhazikika.Mfundo imeneyi ndi apamwamba kuposa mankhwala zitsulo monga mkuwa, chitsulo, zotayidwa, etc., ceramic crucible ali ndi kukana zina asidi, alkali, mchere ndi carbonate kukokoloka mpweya mu mlengalenga, n'zovuta kukhala mankhwala anachita ndi zinthu izi, osati dzimbiri. kukalamba.
(4) Kukhazikika kwamafuta abwino komanso kusamutsa kutentha pang'onopang'ono.Ceramic crucible imakhala ndi ntchito yopita ku kutentha kwina, komwe kuli bwino kuposa glassware, ndi conductor woipa wa kutentha, kutentha pang'onopang'ono, kugwiritsira ntchito madzi otentha kapena njira yotentha, mapeto ake sakhala otentha kwambiri.
Product Application
Alumina ndi ambiri ntchito, zamagetsi, mafuta, mankhwala, refractory, zoumba, mapulasitiki, nsalu, mapepala, ndi mankhwala ndi madera ena ambiri tingaone chithunzi chake, zambiri katundu wapadera wa aluminiyamu ndi zotayidwa hydroxide.Komabe, zoposa 90 peresenti ya aluminiyamu imagwiritsidwa ntchito ngati zopangira za aluminiyamu ya electrolytic.
Pakalipano, pali mitundu yambiri ya mankhwala omwe si aluminiyamu, mitundu yoposa 300, yomwe ili ndi katundu wabwino kwambiri wa thupi ndi mankhwala, koma mtengo wake ndi wapamwamba kwambiri kuposa alumina wochizira.
Mu chiyero chapamwamba cha ultrafine alumina, mwachitsanzo, chifukwa cha malo ake osungunuka kwambiri, kuuma kwakukulu, kukana kwakukulu, katundu wamakina abwino, kuvala kukana, kukana kwa dzimbiri, kukana kutentha ndi zina zabwino kwambiri za 2.Main Features, motero amagwiritsidwa ntchito kwambiri pazinthu za kristalo imodzi. , zadothi zapamwamba, fupa lochita kupanga, semiconductor, zida zogaya, gawo lapansi lophatikizana, chojambulira matepi, chothandizira ndi chonyamulira chake, zida za laser, zida zodulira, ndi zina zambiri.
