Zirconia ceramics vs silicon carbide ceramics: chifukwa chiyani mafakitale apamwamba amakonda silicon carbide?

M'munda wa zipangizo zamakono mafakitale, zirconia ceramics ndisilicon carbide ceramicszonse ndi zida zapamwamba zomwe zakopa chidwi. Komabe, pali kusiyana kwakukulu m'makhalidwe awo, makamaka m'madera ovuta kwambiri monga kutentha kwakukulu, kukana kuvala, ndi kukana kwa dzimbiri. Silicon carbide ceramics amawonetsa zabwino zambiri. Nkhaniyi iwunika kusasinthika kwa zoumba za silicon carbide motengera momwe mungagwiritsire ntchito.

1, 'Wankhondo waluso' pabwalo lankhondo lotentha

Zofunika kukhazikika kwa zipangizo pansi pa kutentha kwambiri ndizovuta kwambiri. Pamene zirconia ceramics zili pamwamba pa 1200 ℃, mawonekedwe awo amkati a kristalo amatha kusintha, zomwe zimapangitsa kusintha kwa voliyumu komanso kusweka, zomwe zimalepheretsa kugwiritsa ntchito kwawo nthawi yayitali kutentha kwambiri. Ma silicon carbide ceramics amatha kukhala okhazikika m'malo opitilira 1350 ℃, kuwapanga kukhala chisankho chabwino pang'anjo zotentha kwambiri, chitetezo cham'mlengalenga, ndi magawo ena.

2. Zovuta zapakati zimavala zosagwira, moyo wautali

Zirconia ceramics zimadziwika chifukwa cha kulimba kwake ndipo ndizoyenera kugwiritsa ntchito zomwe zimafuna kukana kukhudzidwa, monga zida zodulira ceramic kapena zolumikizira zopangira. Koma m'mafakitale omwe amakumana ndi kukangana kwa nthawi yayitali komanso kukokoloka kwa tinthu, mawonekedwe a "superhard" a silicon carbide (Mohs hardness 9.5, wachiwiri kwa diamondi) ndizovuta kwambiri.

Mwachitsanzo, m'mbale zomangira zosavala zamakina amigodi ndi zida zosindikizira zamapampu amadzimadzi, moyo wautumiki wa silicon carbide ukhoza kufika kangapo kuposa zirconia, ndikuchepetsa kwambiri mtengo wokonza zida.

3, Kukana kwa dzimbiri: malo ovuta kwambiri

Zirconia ceramics zitha kutenthedwa ndi zidulo zamphamvu kapena nthunzi yotentha kwambiri, pomwe silicon carbide imakhala ndi mphamvu yolimbana ndi zowononga zambiri. Ndikoyenera kutchula kuti mumlengalenga wotentha kwambiri wa okosijeni, wosanjikiza wandiweyani wa silicon dioxide umapangidwa pamwamba pa silicon carbide, ndikuchedwetsanso kutulutsa kwazinthuzo. Njira yodzitchinjiriza iyi imathandiza kuti izitha kuchita bwino kwambiri m'malo owononga monga makina otulutsa mpweya wa flue komanso zida zamagetsi zotulutsa mpweya.

mapeto

Zirconia ceramics zimakhala ndi malo azachipatala ndi ogula chifukwa cha kulimba kwawo kwakukulu, pamene zoumba za silicon carbide zakhala "ace yamtengo wapatali" ya mafakitale apamwamba monga mphamvu, mankhwala, ndi semiconductor chifukwa cha kukhazikika kwa kutentha, kukana kuvala kwambiri, ndi kusakhazikika kwa mankhwala. Ndi chitukuko chaukadaulo, kugwiritsa ntchito kwatsopano kwa silicon carbide kumakulitsa malire ake, kupereka mayankho odalirika pakukweza mafakitale.

SHANDONG ZHONGPENG SEPCIAL CERAMICS CO., LTD wakhala akugwira ntchito kwambiri pazadothi zadothi kwa zaka zoposa 10, kuyang'ana pa kafukufuku ndi kupanga makonda a silicon carbide ceramics, kuthandiza makasitomala kuthana ndi mikhalidwe yovuta kwambiri yogwirira ntchito ndi zovuta.
