'wosewera mozungulira' mu banja la silicon carbide ceramic - kuwulula zomwe sintered silicon carbide

M'mafakitale amakono, zoumba za silicon carbide zimadziwika kuti "zida zamafakitale" ndipo zakhala zofunikira kwambiri m'malo ovuta kwambiri chifukwa champhamvu zawo, kukana kutentha kwambiri, komanso kukana dzimbiri. Koma zimene anthu ambiri sadziwa kuti pakachitsulo carbide ceramic banja kwenikweni ali angapo mamembala, ndi njira zosiyanasiyana kukonzekera kuwapatsa wapadera "umunthu". Lero tikambirana za mitundu yofala kwambirisilicon carbide ceramicsndi kuwulula ubwino wapadera wa reaction sintered silicon carbide, ukadaulo woyambira wamabizinesi.
1, "Abale Atatu" a Silicon Carbide Ceramics
Kuchita kwa silicon carbide ceramics kumatengera momwe amakonzekera. Pakali pano pali mitundu itatu yodziwika bwino:
1. Non pressure sintered pakachitsulo carbide
Mwa kuumba mwachindunji silicon carbide ufa kudzera pamwamba kutentha sintering, ali ndi kachulukidwe mkulu ndi kuuma amphamvu, koma kukonzekera kutentha ndi okwera ndipo mtengo wake ndi okwera mtengo, kupanga kukhala oyenera tinthu tating'ono mwatsatanetsatane ndi zofunika kwambiri ntchito.
2. Hot mbamuikha sintered silicon carbide
Kupangidwa pansi pa kutentha kwakukulu ndi kupanikizika kwakukulu, kumakhala ndi mawonekedwe owundana komanso kukana kwambiri kuvala, koma zidazo zimakhala zovuta komanso zovuta kupanga zigawo zazikulu kapena zovuta zooneka ngati zooneka bwino, zomwe zimalepheretsa ntchito yake.
3. Reaction sintered silicon carbide (RBSiC)
Poyambitsa zinthu za silicon mu silicon carbide zopangira ndikugwiritsa ntchito ma chemical reaction kudzaza mipata yazinthu, kutentha kwa ndondomeko kumakhala kochepa, kuzungulira kwake kumakhala kochepa, ndipo zigawo zazikulu ndi zosasinthika zimatha kupangidwa mosavuta. Mtengo wake ndiwopambana, ndikuupanga kukhala mtundu wogwiritsidwa ntchito kwambiri wa silicon carbide m'mafakitale.

2, Chifukwa chiyani sintered silicon carbide imakondedwa kwambiri?
Monga chinthu chofunikira kwambiri pabizinesi, njira yapadera yochitira sintered silicon carbide (RBSiC) imapangitsa kukhala "chinthu chokondedwa" m'mafakitale ambiri. Ubwino wake ukhoza kufotokozedwa mwachidule ndi mawu atatu:
1. Yamphamvu ndi yolimba
The reaction sintering process imapanga "interlocking structure" mkati mwa zinthuzo, zomwe zimatha kukana kutentha kwambiri kwa 1350 ℃ ndipo zimakhala ndi kukana kwamphamvu kwambiri komanso kutentha kwambiri - osawonongeka mosavuta pakuvala kwapamwamba komanso kutentha kwambiri, makamaka koyenera paziwonetsero zotentha kwambiri monga zida zamoto ndi zoyatsira.
2. Pitani kunkhondo ndi zida zowunikira
Poyerekeza ndi zipangizo chikhalidwe zitsulo, anachita sintered pakachitsulo carbide ali m'munsi kachulukidwe koma angapereke mlingo womwewo wa mphamvu, kuchepetsa kwambiri kugwiritsa ntchito zipangizo mphamvu. Mwachitsanzo, m'makampani a photovoltaic, zida zopepuka za silicon carbide zimatha kusintha kwambiri magwiridwe antchito a ng'anjo imodzi ya kristalo.
3. Wosinthika komanso wosinthasintha
Kaya ndi ma tray a semiconductor okhala ndi mainchesi opitilira 2 metres, ma nozzles ovuta, mphete zosindikizira, kapena magawo opangidwa makonda okhala ndi mawonekedwe osiyanasiyana, ukadaulo wa sintering ukhoza kuwongolera bwino mawonekedwe ndi kukula kwake, ndikuthetsa vuto la kupanga "lalikulu komanso lolondola".
3, 'mphamvu yosaoneka yoyendetsa' ya kukweza kwa mafakitale
"Chiwerengero" cha reaction sintered silicon carbide chalowa m'magawo angapo, kuyambira njanji zosagwirizana ndi kukokoloka m'ng'anjo zazitsulo mpaka mapaipi osachita dzimbiri pazida zamankhwala. Kukhalapo kwake sikumangowonjezera nthawi ya moyo wa zida, komanso kumathandiza mabizinesi kupeza mphamvu zosungira mphamvu ndi kuchepetsa kugwiritsira ntchito mphamvu - mwachitsanzo, m'munda wa ng'anjo za mafakitale, kugwiritsa ntchito mipando ya silicon carbide kiln ikhoza kuchepetsa kwambiri kutentha kwa kutentha.

Mapeto
'Kuthekera' kwa zoumba za carbide kumapitilira izi. Monga mpainiya waukadaulo wa reaction sintering, timakulitsa nthawi zonse kuti tipeze phindu lazinthuzi m'malo ovuta kwambiri. Ngati mukuyang'ana njira zamafakitale zomwe sizingatenthe kutentha, zosagwira ntchito, komanso kukhala ndi moyo wautali, mungafune kulabadira mwayi wochulukirapo wa silicon carbide ceramics!
Shandong Zhongpeng wakhala akuyang'ana kwambiri pa kafukufuku ndi kupanga zomwe sintered silicon carbide kwa zaka zoposa khumi, kupereka mayankho makonda a ceramic kwa makasitomala apadziko lonse lapansi.
