Silikoni carbide yopangidwa ndi mpweya wozizira siigwiritsidwanso ntchito ngati chinthu chonyamulira, koma ngati chinthu chatsopano, ndipo imagwiritsidwa ntchito kwambiri pazinthu zamakono, monga zoumba zopangidwa ndi zinthu za silicon carbide. Ndiye ubwino wa silicon carbide wotentha mpweya wozizira ndi kugwiritsa ntchito zoumba ...
Ubwino asanu ndi limodzi wa zipangizo za silicon carbide zoponderezedwa ndi mpweya:
1. Kuchuluka kochepa
Zipangizo za silicon carbide zimakhala ndi kachulukidwe kochepa kuposa chitsulo, zomwe zimapangitsa chipangizocho kukhala chopepuka.
2. Kukana dzimbiri
Zinthu za silicon carbide zimakhala ndi malo osungunuka kwambiri, mankhwala osagwira ntchito bwino, kutentha kwambiri, silicon carbide imagwiritsidwa ntchito mu ma abrasives, ma ceramic kilns, silicon carbide blanks, ndipo ingagwiritsidwe ntchito mumakampani osungunulira ndi kusungunulira ndi vertical silinda distillation furnace, njerwa, aluminiyamu electrolytic cell lining, tungsten, small furnace ndi zinthu zina za silicon carbide ceramic.
3, kutentha kwakukulu, kutentha koyezera kukula kwa kutentha kumachepa
Zinthu za silicon carbide zimapangidwa kutentha kwambiri. M'malo ena otentha kwambiri, zinthu zomwe zimafuna mphamvu yokonza ndi kulondola komwe silicon carbide ceramics ingakwanitse zimafunika. Kutentha kwakukulu kwa silicon carbide ndi pafupifupi 800, ndipo kutentha kwa chitsulo ndi 250 zokha. Kuwerengera koyipa, kuchuluka kwapakati kwa kutentha kwa silicon carbide komwe kuli pakati pa 25 ~ 1400 ndi 4.10-6 /C. Kuchuluka kwa kutentha kwa silicon carbide kumayesedwa, ndipo zotsatira zake zikuwonetsa kuti kuchuluka kwake ndi kochepa kwambiri kuposa kwa zinthu zina zowononga komanso zinthu zotentha kwambiri. Sintered silicon carbide pansi pa kupsinjika kwa mlengalenga.
4, kutentha kwakukulu
Mphamvu ya kutentha ya zinthu za silicon carbide ndi yayikulu, yomwe ndi chinthu china chofunikira kwambiri pa mphamvu ya silicon carbide. Mphamvu ya kutentha ya silicon carbide ndi yayikulu kwambiri kuposa ya zinthu zina zotsutsana ndi ma abrades, pafupifupi nthawi 4 kuposa ya corundum. Silicon carbide ili ndi mphamvu yochepa ya kutentha komanso mphamvu ya kutentha kwambiri, kotero chogwirira ntchitocho chidzakumana ndi kupsinjika pang'ono kwa kutentha panthawi yotenthetsera ndi kuzizira. Ichi ndichifukwa chake zigawo za SiC zimalimbana kwambiri ndi kugwedezeka.
5, mphamvu yayikulu yamakina, kuuma bwino
Mphamvu ya makina ya zinthu za silicon carbide ndi yayikulu kwambiri, zomwe zimalepheretsa kusintha kwa zinthu. Silicon carbide ili ndi mphamvu yamakina yoposa corundum.
6, kuuma kwambiri komanso kukana kuvala
Kuuma kwa zinthu za silicon carbide n'kokwera kwambiri, ndipo kuuma kwa Moss gap ndi 9.2 ~ 9.6, yachiwiri pambuyo pa diamondi ndi tungsten carbide. Poyerekeza ndi zinthu zachitsulo, imapereka kuuma kwakukulu, kukhuthala kochepa, kukhuthala kochepa, kukhwima pang'ono pamwamba komanso kukana bwino kuvala popanda mafuta. Kuphatikiza apo, imalimbana ndi zinthu zakunja, zomwe zimapangitsa kuti pamwamba pakhale kulekerera. Sintered silicon carbide pansi pa kupsinjika kwa mlengalenga
Kugwiritsa ntchito chitsulo cha silicon carbide chopangidwa ndi mlengalenga
1, kupanga zinthu zapadera za silicon carbide
Zinthu zopangidwa ndi silicon carbide ndi zinthu zolimba kwambiri komanso zotsika mtengo, zomwe zimatha kupanga zinthu zopangidwa ndi silicon carbide, monga zisindikizo za silicon carbide, manja a silicon carbide, mbale zoteteza zipolopolo za silicon carbide, ma profiles a silicon carbide, ndi zina zotero, zomwe zingagwiritsidwe ntchito pa zisindikizo zamakina ndi mapampu osiyanasiyana. Sintered silicon carbide pansi pa kupsinjika kwa mlengalenga.
2, kupanga zinthu za zirconia za ziwiya zapadera
Zirconia ceramic ili ndi ma ionic conductivity apamwamba, kukhazikika kwa mankhwala abwino komanso kukhazikika kwa kapangidwe kake, ndipo yakhala chinthu chophunziridwa kwambiri komanso chogwiritsidwa ntchito ndi ma electrolyte. Mwa kukonza njira yopangira filimu ya electrolyte yochokera ku zirconia, kuchepetsa kutentha kogwirira ntchito ndi mtengo wopanga zinthuzi, komanso kuyesetsa kukwaniritsa mafakitale ndi njira yofunika kwambiri yofufuzira mtsogolo.
