silicon carbide ceramic kutentha kwa ma conductivity

Pambali pa uvuni wa 1000 ℃, mu makina oteteza chilengedwe a mafakitale, komanso mkati mwa zida zowunikira molondola, nthawi zonse pamakhala chinthu chomwe chimapirira kutentha kwambiri - ndichozoumbaumba za silicon carbidechodziwika kuti "golide wakuda wa mafakitale". Monga chinthu chofunikira kwambiri m'mafakitale amakono, mphamvu za kutentha zomwe zimawonetsedwa ndi ziwiya za silicon carbide zikukonzanso kumvetsetsa kwa anthu pazinthu zotentha kwambiri.

1, 'Njira yofulumira' yoyendetsera kutentha
Ma silicon carbide ceramics ali ndi mphamvu yoyendetsera kutentha yofanana ndi zitsulo, yokhala ndi mphamvu yoyendetsera kutentha yochulukirapo kangapo kuposa ya zinthu wamba za ceramic. Mphamvu yapaderayi yoyendetsera kutentha imapangidwa ndi maatomu a silicon carbon omwe ali olimba mu kapangidwe kake ka kristalo, omwe amapanga njira zoyendetsera kutentha bwino. Kutentha kukasamutsidwa mkati mwa chinthucho, kumakhala ngati galimoto yoyendetsa pamsewu wopanda chopinga, yomwe imatha kufalitsa kutentha mwachangu komanso mofanana, kupewa zoopsa zachitetezo zomwe zimachitika chifukwa cha kutentha kwambiri m'deralo.
2, Kutalika kwa moyo m'malo otentha kwambiri
Pa kutentha kwakukulu kwa 1350 ℃, zinthu zambiri zachitsulo zimakhala zitafewa kale komanso zitasokonekera, pomwe zinthu za silicon carbide ceramics zimatha kusungabe umphumphu wa kapangidwe kake. Kukana kutentha kwakukulu kumeneku kumachokera ku mgwirizano wamphamvu wa covalent mkati mwa chinthucho, monga kumanga linga laling'ono losawonongeka. Chosowa kwambiri ndichakuti m'malo otentha kwambiri, gawo lolimba la silika limapangidwa pamwamba pake, ndikupanga "chishango choteteza" chachilengedwe.

3, 'Mfumu Yopirira' ya Nkhondo Yopirira Kutentha Kwambiri
Mu mpikisano wa marathon wokhala ndi kutentha kwambiri, zinthu zambiri zimawonongeka chifukwa cha kutentha kwa nthawi yayitali, pomwe zinthu za silicon carbide zozungulira zomwe zimapangidwa ndi reaction sintered zimasonyeza kulimba kodabwitsa. Chinsinsi chili mu kapangidwe kapadera ka tirigu - kapangidwe ka netiweki ka magawo atatu komwe kamapangidwa kudzera muukadaulo wosinthira reaction, komwe kuli ngati kumangirira mamiliyoni a "magawo oyambira" kuzinthuzo. Ngakhale patatha maola masauzande ambiri akuphika kutentha kwambiri, zimathabe kutseka kukhazikika kwa kapangidwe ka microstructure. Khalidweli limapangitsa kuti ikhale chisankho chabwino kwambiri chosinthira zinthu zachitsulo zachikhalidwe m'zochitika monga ma roller opitilira muyeso mumakampani opanga zitsulo ndi zida zonyamula katundu kutentha kwambiri muzipangizo zamakemikolo. Limatanthauzira tanthauzo la "kutentha kwakukulu sikutha" ndi "mphamvu yolimba".
Ngati chipangizo chanu chikufunika kuthana ndi malire a kutentha, zinthu zoyeretsera kutentha zomwe zimapangidwa ndi silicon carbide zitha kukhala 'wolamulira kutentha' wodalirika. Monga katswiri wamakampani omwe amagwira ntchito yokonza ukadaulo woyeretsera kutentha,Shandong Zhongpengimagwiritsa ntchito ukadaulo wosiyanasiyana wokhala ndi patent kuti iwonjezere mphamvu ya makina ndi magwiridwe antchito a zinthuzo pamene ikusunga mphamvu zabwino kwambiri za kutentha. Kupita patsogolo kwaukadaulo kumeneku sikungochepetsa ndalama zopangira, komanso kukuwonetsa mwayi waukulu wogwiritsa ntchito zinthu za silicon carbide m'mafakitale omwe akutukuka kumene.
