Mawonekedwe

Akhali a ric, makamaka opangidwa kuchokera ku silicon carbide, amagwiritsidwa ntchito kwambiri m'makampani omwe kutentha kwambiri ndi kukana kwa mankhwala ndikofunikira. Izi zolimbazi zakhala zosankha za ounda ndi ma labotori chifukwa cha kulimba kwawo kwakukulu, ndikuwapangitsa kuti azifunikira kuti azikhala ngati chitsulo chosungunuka, kuponyera, ndi kuyenderera.

Mukamasankha zolimba za mafakitale, kumvetsetsa zolemba zakuthupi ndi zamankhwala ndikofunikira. Pansipa pali kuwonongeka kwa malo ofunikira a ISO mtundu wa sic:

Katundu wathupi Mapeto
Kuthetsana ≥ 1650 ° C
Zikuwoneka zowoneka bwino ≤ 20%
Kuchulukitsa Kwambiri ≥ 2.2 g / cm²
Kuphwanya mphamvu ≥ 85 MPA
Kuphatikizika kwa mankhwala Mapeto
Mitundu ya carbon (c%) 20-30%
Silicon Carbide (sic%) 50-60%
Alumina (al2o3%) 3-5%

Makhalidwe awa amapereka mphamvu zapadera zanzeru kwambiri, kuwonjezeka kwamafuta ochulukirapo, komanso kukana mankhwala kuwononga mankhwala, kuonetsetsa kuti akuchita bwino ngakhale madera oyenda bwino kwambiri.

Zabwino zaokha

  1. Kulimba Kwambiri Kwambiri: Maulambo a SIC amalimbana ndi kutentha mpaka 1650 ° C, kuwapangitsa kukhala abwino kusungunuka kwachitsulo ndi mapulogalamu ena akulu kwambiri.
  2. Kulimba ndi moyo wautali: Ndi mphamvu yamphamvu ya ≥ 8.5 mivi yamphamvu iyi, izi zipsinjozi zimatha kupirira zipsinjo zokhudzana ndi makonda omwe akukhudzidwa ndi makonda kapena kusokonekera.
  3. Kukhazikika kwa mankhwala: Mafuta apamwamba a silican (50-60%) amapereka kukana kwabwino kwa zomwe zimachitika pakukumana ndi ma viru, ngakhale mutakhala ndi moyo wosungunula kapena mankhwala osokoneza bongo.

Kugwira ntchito mosamala ndikusamalira ma ric

Kuti akweze moyo waokhazikika ndi kuwonetsetsa kuti agwiritse ntchito motetezeka, ndikofunikira kutsatira malangizo ochepa okonza:

  • Kuyeretsa pafupipafupi: Zingwe ziyenera kutsukidwa pafupipafupi kuti zichotse chotsalira chilichonse, kupewa kuipitsidwa ndi kututa.
  • Pewani kugwedezeka kwamafuta: Kutentha kwakamwa ndi kuzizira ndikofunikira kuti tipewe kuwonongeka. Kusintha mwadzidzidzi kumatha kuyambitsa zinthuzo kusokonekera.
  • Pewani mankhwala: Pewani kukhudzidwa ndi mankhwala owononga, makamaka alkaline kapena masinthidwe acidic, omwe amatha kunyoza umphumphu.

Kudziwa Zothandiza kwa Ogula

Kusankha wotchinga koyenera kumadalira zosowa zapadera za mafakitale anu. Onani zinthu monga kutentha, kuyenerera zakuthupi, ndi zofunikira zazikulu. M'dziko lenileni ladziko lapansi, ogula ambiri abweretsa kutsika kwakukulu kokwera mtengo ndikuwonjezera mphamvu pokonza ndi kusinthana ndi ziphuphu.

Ziphuphu za SIC ndizo chida chofunikira kwambiri kwa mafakitale omwe amafunikira zinthu zolimbitsa thupi kwambiri zomwe zimatha kuzizira kwambiri komanso kuwonekera kwa mankhwala. Mwa kumvetsetsa katundu wawo ndikutsatira ma protocol oyenera, mabizinesi amatha kukulitsa kugwiritsa ntchito bwino ntchito kwinaku akuchepetsa nthawi.
