M'magawo apamwamba monga ma semiconductors, mphamvu zatsopano, ndi ndege, zinthu zopangidwa ndi ceramic zotuwa ngati imvi zikuchita gawo lofunika kwambiri mwakachetechete.silicon carbide ceramic- chinthu cholimba ngati diamondi, chomwe chikusintha mawonekedwe a mafakitale amakono chifukwa cha kukana kutentha kwambiri, kukana dzimbiri komanso kutentha kwambiri. Koma sizikudziwika bwino kuti kuti ufa wolimba wa silicon carbide ukhale wolondola, njira yamatsenga ya "kupangira kutentha kwambiri" imafunika.
I. Njira Yoyeretsera: Matsenga Ofunika Kwambiri Osinthira Miyala Kukhala Golide
Ngati ufa wa silicon carbide uyerekezeredwa ndi jade wosapukutidwa, njira yopangira sintering ndiyo njira yofunika kwambiri yopangira kuti ikhale chinthu chabwino. Kupyolera mu kupangira kutentha kwambiri pa 800-2000℃, tinthu ta ufa tofanana ndi micron timagwirirana chanza "pamlingo wa atomiki, ndikupanga thupi lolimba komanso lolimba la ceramic. Njira zosiyanasiyana zopangira sintering, monga njira zosiyanasiyana zojambula, zipangizo zokhala ndi mawonekedwe apadera:
1. Kutenthetsa mpweya pang'onopang'ono: Njira yachikhalidwe kwambiri yophikira pang'onopang'ono pa moto wochepa
Monga momwe supu yokoma yophikidwa pang'onopang'ono imafunika kuphikidwa pang'onopang'ono pamoto wochepa, njira imeneyi imalola ufawo kukhuthala mwachilengedwe ngakhale kutentha kwambiri kwa nthawi yayitali. Ngakhale kuti nthawiyi ndi yayitali, imatha kusunga "kukoma koyambirira" kwa zinthuzo ndipo ndi yoyenera kwambiri pazida za semiconductor zomwe zimafunikira kuyera kwambiri.
2. Kukanikiza kotentha: Njira yowongolera bwino "yopangira zinthu pogwiritsa ntchito mphamvu zambiri"
Kugwiritsa ntchito mphamvu ya makina pamalo otentha kwambiri kuli ngati kupereka "massage yotentha" yeniyeni ku chinthucho, chomwe chingachotse mwachangu malo opanda kanthu mkati. Ziwalo zadothi zopangidwa ndi njirayi zimakhala ndi kuchuluka kofanana ndi mtengo wongopeka ndipo ndi chisankho chabwino kwambiri popanga ma bearing ndi seal olondola.
3. Kutulutsa Zinthu Zosiyanasiyana: "Masenga a Mankhwala" mu Dziko la Zipangizo
Pogwiritsa ntchito mwanzeru momwe mankhwala amachitira pakati pa silicon ndi kaboni, malo opanda kanthuwo amadzazidwa okha panthawi yothira mafuta. Mbali iyi ya "kudzichiritsa" imapangitsa kuti ikhale chida champhamvu chopangira zinthu zovuta komanso zosakhazikika, zoyenera zinthu zosiyanasiyana zopirira kutentha kwambiri, zosatha, zosagwira dzimbiri kapena zinthu zina zomwe zasinthidwa.
Ii. Kusankha Njira: Nzeru Yosoka Kuti Igwirizane
Monga momwe osoka okalamba amasankhira zosokera kutengera mawonekedwe a nsalu, mainjiniya ayenera kuganizira mozama zofunikira pa chinthucho:
Pogwira ntchito ndi ziwalo zosaoneka bwino zokhala ndi makoma owonda, "ukadaulo wolowera" wa kupopera kwa reaction ungathe kukhala ndi mawonekedwe abwino kwambiri.
Mathireyi a semiconductor okhala ndi zofunikira kwambiri pa malo osalala kwambiri amatha kuwonetsetsa kuti palibe kusintha kulikonse chifukwa cha kupanikizika kwabwinobwino
Pogwira ntchito ndi zinthu zolemera kwambiri, kuchuluka kwamphamvu kwambiri kwa sintering yotenthetsera nthawi zambiri kumasankhidwa
III. Kupambana kwa Ukadaulo Kosaoneka
Mu mbiri ya kusintha kwa ukadaulo wopangira zinthu zopanga zinthu zonga zinthu, zinthu ziwiri zobisika ndizofunikira kwambiri: kuwonjezera zinthu zopanga zinthu zonga ...
Kuchokera ku mafakitale osatha kutopa komanso osatha dzimbiri mpaka kumakampani apamwamba a semiconductor, ma silicon carbide ceramics akukonzanso mawonekedwe amakampani amakono. Kupangidwa kwatsopano kosalekeza kwa ukadaulo wothira zinthu kuli ngati kupereka mapiko kuzinthu zamatsenga izi, zomwe zimathandizira kuti ziwuluke mumlengalenga waukulu. Monga wopanga waluso yemwe wakhala akugwira ntchito kwambiri mu gawo la ma silicon carbide ceramics kwa zaka zoposa khumi, Shandong Zhongpeng amamvetsetsa bwino kukambirana pakati pa zipangizo ndi kuwongolera kutentha kuposa wina aliyense. Kusintha kulikonse kwa sintering curve ndi kukonzanso kwa "nthawi yotenthetsera-kupanikizika" yagolide. Kuthwanima kwa ng'anjo iliyonse ndi moto wa uvuni kumapitiliza kulemba mutu wosintha wa ma ceramics a mafakitale. Podalira chidaliro cha kafukufuku wodziyimira pawokha komanso ukadaulo wambiri wokhala ndi patent, nthawi zonse timadzipereka kupatsa makasitomala yankho limodzi kuyambira kuyeretsa zinthu zopangira mpaka kuthira zinthu molondola, kuonetsetsa kuti chinthu chilichonse cha silicon carbide ceramic chimanyamula kutentha kwa zaka khumi zaukadaulo. Njira yomwe ili patsogolo imachepetsedwa, ndipo kudzera mu kupanga mobwerezabwereza, imakhala yatsopano. Tikukupemphani moona mtima kuti mudzayanjane nafe kuti muwone momwe kuwala kwanzeru kumeneku mu ma ceramics amakampani kumawunikira zosatheka zambiri. Nthawi zonse timakhulupirira kuti kupita patsogolo kulikonse mu sayansi ya zinthu kumawonjezera mphamvu kuti anthu adutse malire a ukadaulo.
