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

Mu gawo la zipangizo zamakono zamafakitale, zirconia ceramics ndizoumbaumba za silicon carbideZonsezi ndi zinthu zogwira ntchito bwino kwambiri zomwe zakopa chidwi cha anthu ambiri. Komabe, pali kusiyana kwakukulu pa makhalidwe awo, makamaka m'malo ovuta kwambiri monga kutentha kwambiri, kukana kuwonongeka, komanso kukana dzimbiri. Zida za silicon carbide zimawonetsa zabwino zambiri. Nkhaniyi ifufuza kusasinthika kwa zida za silicon carbide kuchokera pamalingaliro ogwiritsira ntchito.

1, 'Msilikali wodziwa bwino ntchito' pankhondo yotentha

Zofunikira pa kukhazikika kwa zinthu zomwe zili ndi kutentha kwambiri zimakhala zovuta kwambiri. Zirconia ceramics zikafika pa 1200 ℃, kapangidwe kake ka kristalo kamasintha, zomwe zimapangitsa kuti voliyumu isinthe komanso kusweka, zomwe zimapangitsa kuti zisamagwiritsidwe ntchito m'malo otentha kwambiri kwa nthawi yayitali. Zirconia ceramics zimatha kusunga kukhazikika kwa kapangidwe kake m'malo otentha kwambiri kuposa 1350 ℃, zomwe zimapangitsa kuti zikhale chisankho chabwino kwambiri cha ng'anjo zotentha kwambiri, chitetezo cha kutentha kwa mlengalenga, ndi zina zotero.

2, Zovuta pakati zotchinga zosagwira, nthawi yayitali yopuma

Zirconia ceramics zimadziwika ndi kulimba kwawo ndipo ndizoyenera kugwiritsidwa ntchito zomwe zimafuna kukana kugwedezeka, monga zida zodulira za ceramic kapena zolumikizira zopangira. Koma m'mafakitale omwe amakumana ndi kukangana kwa nthawi yayitali komanso kuwonongeka kwa tinthu tating'onoting'ono, makhalidwe a "superhard" a silicon carbide (kulimba kwa Mohs 9.5, yachiwiri pambuyo pa diamondi) ndi ofunikira kwambiri.

Mwachitsanzo, m'mapepala olumikizirana a makina opangira migodi ndi zida zotsekera za mapampu a mankhwala osatha, moyo wa silicon carbide ukhoza kufika kangapo kuposa wa zirconia, zomwe zimachepetsa kwambiri ndalama zokonzera zida.

3, Kukana dzimbiri: zovuta kwambiri

Zirconia ceramics zimatha kuzizira mu asidi amphamvu kapena nthunzi yotentha kwambiri, pomwe silicon carbide imakana kwambiri njira zambiri zowononga. Ndikoyenera kunena kuti mumlengalenga wotentha kwambiri, gawo loteteza la silicon dioxide lidzapangidwa pamwamba pa silicon carbide, zomwe zimachedwetsa kwambiri njira yowononga zinthuzo. Njira yodzitetezera iyi imalola kuti igwire bwino ntchito m'malo owononga monga makina ochotsera mpweya woipa komanso zida zotsukira mpweya wotuluka.

mapeto

Zirconia ceramics ili ndi malo m'magawo azachipatala ndi ogula chifukwa cha kulimba kwawo kwabwino, pomwe silicon carbide ceramics yakhala "ace yazinthu" m'mafakitale apamwamba monga mphamvu, mankhwala, ndi semiconductor chifukwa cha kukhazikika kwawo kutentha kwambiri, kukana kuvala kwambiri, komanso kusagwira ntchito kwa mankhwala. Ndi chitukuko cha ukadaulo, kugwiritsa ntchito kwatsopano kwa silicon carbide kukukulitsa malire ake nthawi zonse, kupereka mayankho odalirika kwambiri pakukweza mafakitale.

SHANDONG ZHONGPENG SEPCIAL CERAMICS CO., LTD yakhala ikugwira ntchito mwakhama pa ntchito ya zoumbaumba zapamwamba kwa zaka zoposa 10, ikuyang'ana kwambiri pa kafukufuku ndi kupanga zinthu zopangidwa mwamakonda za zoumbaumba za silicon carbide, kuthandiza makasitomala kuthana ndi mavuto ndi zovuta zogwirira ntchito. Kuti mudziwe zambiri zokhudza zinthu, werengani zambiri.malingaliro, chonde musazengereze kutilankhulana nafe pa (+86) 15254687377!
