Mu gawo lamakono la mafakitale, zoumba za silicon carbide zimadziwika kuti "zida za mafakitale" ndipo zakhala zofunika kwambiri m'malo ovuta kwambiri chifukwa cha mphamvu zawo zapamwamba, kukana kutentha kwambiri, komanso kukana dzimbiri. Koma chomwe anthu ambiri sadziwa ndichakuti banja la silicon carbide ceramic lili ndi mamembala angapo, ndipo njira zosiyanasiyana zokonzekera zimawapatsa "umunthu" wapadera. Lero tikambirana za mitundu yodziwika bwino yazoumbaumba za silicon carbidendikuwonetsa ubwino wapadera wa reaction sintered silicon carbide, ukadaulo waukulu wa mabizinesi.
1、“Abale Atatu” a Silicon Carbide Ceramics
Kagwiridwe ka ntchito ka silicon carbide ceramics kamadalira kwambiri njira yokonzekera. Pakadali pano pali mitundu itatu yayikulu:
1. Silikoni carbide yosakanizidwa ndi kupanikizika
Mwa kuumba mwachindunji ufa wa silicon carbide kudzera mu sintering yotentha kwambiri, imakhala ndi kuchuluka kwakukulu komanso kuuma kwamphamvu, koma kutentha kokonzekera kumakhala kokwera ndipo mtengo wake ndi wokwera mtengo, zomwe zimapangitsa kuti ikhale yoyenera pazinthu zazing'ono zolondola zomwe zimafunikira magwiridwe antchito apamwamba kwambiri.
2. Silikoni carbide yotenthedwa ndi sintered
Yopangidwa ndi kutentha kwambiri komanso kuthamanga kwambiri, ili ndi kapangidwe kolimba komanso yolimba kwambiri, koma zida zake ndi zovuta kupanga zinthu zazikulu kapena zooneka ngati zovuta, zomwe zimalepheretsa kugwiritsidwa ntchito kwake.
3. Kapangidwe ka silikoni kabodi (RBSiC)
Mwa kuyika zinthu za silicon mu zinthu zopangira silicon carbide ndikugwiritsa ntchito mankhwala kuti azitha kudzaza mipata ya zinthu, kutentha kwa njira kumakhala kochepa, nthawi yake ndi yochepa, ndipo zigawo zazikulu komanso zosakhazikika zimatha kupangidwa mosavuta. Kugwiritsa ntchito bwino ndalama kwake ndikodabwitsa, zomwe zimapangitsa kuti ikhale mtundu wa silicon carbide womwe umagwiritsidwa ntchito kwambiri m'mafakitale.
2, N’chifukwa chiyani kabodi ya silikoni yopangidwa ndi reaction sintered imakondedwa kwambiri?
Monga chinthu chachikulu cha bizinesi, njira yapadera ya reaction sintered silicon carbide (RBSiC) imapangitsa kuti ikhale "chinthu chomwe chimakondedwa" m'mafakitale ambiri. Ubwino wake ukhoza kufotokozedwa mwachidule ndi mawu atatu ofunikira:
1. Yamphamvu komanso yolimba
Njira yopangira zinthu zoyatsira moto imapanga "kapangidwe kolumikizana" mkati mwa chinthucho, komwe kumatha kupirira kutentha kwambiri kwa 1350 ℃ ndipo kumakhala kolimba kwambiri pakutha komanso kutentha kwambiri - sikuwonongeka mosavuta m'malo owonongeka kwambiri komanso kutentha kwambiri, makamaka koyenera pazochitika zotentha kwambiri monga zowonjezera mu uvuni ndi zoyatsira moto.
2. Pitani kunkhondo ndi zida zopepuka
Poyerekeza ndi zipangizo zachitsulo zachikhalidwe, silicon carbide yopangidwa ndi reaction sintered ili ndi mphamvu yochepa koma imatha kupereka mphamvu yofanana, zomwe zimachepetsa kwambiri kugwiritsa ntchito mphamvu kwa zida. Mwachitsanzo, mumakampani opanga ma photovoltaic, zida zopepuka za silicon carbide zimatha kusintha kwambiri magwiridwe antchito a uvuni umodzi wa kristalo.
3. Wosinthasintha komanso wosinthasintha
Kaya ndi ma tray a semiconductor okhala ndi mainchesi opitilira 2, nozzles zovuta, mphete zotsekera, kapena magawo opangidwa mwamakonda okhala ndi mawonekedwe osiyanasiyana, ukadaulo wochita zinthu mopupuluma ukhoza kuwongolera mawonekedwe ndi kukula molondola, kuthetsa vuto lopanga "lalikulu komanso lolondola".
3, 'Mphamvu yosaoneka yoyendetsera ntchito' yokonzanso mafakitale
"Chithunzi" cha silicon carbide yopangidwa ndi reaction sintered chalowa m'magawo angapo, kuyambira pa njanji zowongolera zomwe sizikukhudzidwa ndi kukokoloka kwa nthaka m'zitofu zachitsulo mpaka mapaipi osakhudzidwa ndi dzimbiri muzipangizo zamankhwala. Kukhalapo kwake sikuti kumawonjezera nthawi ya moyo wa zida, komanso kumathandiza mabizinesi kusunga mphamvu ndi kuchepetsa kugwiritsa ntchito - mwachitsanzo, m'munda wa ma uvuni amafakitale, kugwiritsa ntchito mipando ya silicon carbide muzipangizo za uvuni kumatha kuchepetsa kwambiri kutayika kwa kutentha.
Mapeto
'Kuthekera' kwa zoumba za carbide kumapitirira izi. Monga mtsogoleri muukadaulo wochita zinthu zotsutsana ndi reaction, timapitiliza kukonza njirayi kuti tiwonjezere phindu la zinthuzi m'malo ovuta kwambiri. Ngati mukufuna njira zamafakitale zomwe sizimatentha, sizimagunda, komanso zimakhala ndi moyo wautali, mungafune kulabadira mwayi wochulukirapo wa zoumba za silicon carbide!
Shandong Zhongpeng yakhala ikuyang'ana kwambiri pa kafukufuku ndi kupanga kwa silicon carbide yopangidwa ndi reaction sintered kwa zaka zoposa khumi, kupereka mayankho opangidwa mwamakonda a ceramic kwa makasitomala apadziko lonse lapansi.
