Chosinthira kutentha cha Silicon carbide: njira yabwino yoyendetsera kutentha m'malo ovuta kwambiri

Mu gawo la mafakitale komwe kutentha kwambiri, zinthu zowononga, komanso ntchito zoopsa kwambiri zimachitika nthawi zambiri, zipangizo zachikhalidwe nthawi zambiri zimakhala zosakwanira. Monga mtsogoleri muukadaulo wa silicon carbide ceramic, tikudziwa bwino momwe zinthu zatsopanozi zimasinthira malire aukadaulo wosinthana kutentha. Nkhaniyi ikukuthandizani kumvetsetsa chifukwa chakezosinthira kutentha kwa silicon carbideakhala "okonda chilichonse" m'malo ovuta.
Ubwino Wachinayi Wapakati wa Silicon Carbide
Silicon carbide (SiC) ndi chinthu chapamwamba cha ceramic chomwe chimapangidwa mwaluso, ndipo kuphatikiza kwake kwapadera kwa zinthu kumapangitsa kuti ikhale chisankho chabwino kwambiri pazida zosinthira kutentha pamikhalidwe yovuta kwambiri yogwirira ntchito.
1. Kutentha kwabwino kwambiri
Mphamvu ya kutentha ya silicon carbide imaposa mphamvu ya zinthu zachitsulo monga chitsulo chosapanga dzimbiri, ndipo imatha kusamutsa kutentha mwachangu m'malo otentha kwambiri, zomwe zimapangitsa kuti mphamvu zigwiritsidwe ntchito bwino komanso kuchepetsa kuchuluka kwa zida.
2. Osaopa kutentha kwambiri
Zipangizo zachitsulo zimatha kufewa komanso kusinthika zikatentha kwambiri, pomwe silicon carbide imatha kusunga kukhazikika kwa kapangidwe kake m'malo opitilira 1350 ° C, zomwe zimapangitsa kuti ikhale bwenzi lodalirika kwa nthawi yayitali pazida monga ma uvuni otentha kwambiri ndi ma reactor a mankhwala.

3. Katswiri wachilengedwe wothana ndi dzimbiri
Kaya m'malo owononga monga ma asidi amphamvu kapena okhala ndi mchere wambiri, gawo loteteza la oxide lidzapangidwa lokha pamwamba pa silicon carbide kuti lipewe kuwonongeka kwa mankhwala ndikuchepetsa kwambiri kuchuluka kwa kukonza.
Chofunika kwambiri cha njira yochitira zinthu zowononga
Ukadaulo wathu waukulu, reaction sintered silicon carbide (RBSC), umapanga zinthu zokhuthala komanso zofanana za ceramic mwa kulowetsa zinthu za silicon mu matrix ya carbon yomwe ili ndi porous. Kupambana kwaukadaulo kumeneku kumabweretsa zabwino zitatu zazikulu:
-Chepetsani zofooka zomwe zimayambitsidwa ndi ma pores amkati mwa zinthu zachikhalidwe zosinjidwa
-Bweretsani molondola mapangidwe ovuta a njira zoyendera kuti muwongolere bwino kusamutsa kutentha
- Kulinganiza magwiridwe antchito apamwamba komanso kulamulira mtengo
Kukhazikika kwa nthawi yayitali, kuchepetsa ndalama mu moyo wonse
Kusintha pafupipafupi kwa zinthu zosinthira kutentha zachitsulo chifukwa cha dzimbiri ndi kukula kwakhala mbiri yakale. Kulimba kwa zinthu za silicon carbide kumapangitsa kuti zinthu zisamavutike kugwira ntchito panthawi yoyika, zomwe zimapangitsa kuti zinthuzi zizigwira ntchito bwino nthawi yonse ya moyo wa chipangizocho.
Monga katswiri wodziwa bwino ntchito ya silicon carbide yopangidwa ndi zinthu zotsutsana ndi zinthu zotsutsana kwa zaka zoposa 20,Shandong Zhongpengnthawi zonse wakhala akudzipereka kupereka njira zoyendetsera kutentha kwa makasitomala. Kaya mukufuna kukonza makina omwe alipo kapena kupanga zida zatsopano, gulu lathu lidzakuthandizani kutulutsa mphamvu zonse za zinthu za silicon carbide.
