Kupanikizika kwa mumlengalenga kunadutsasilicon carbidesichimagwiritsidwanso ntchito ngati chotupitsa, koma ngati chinthu chatsopano, ndipo chimagwiritsidwa ntchito kwambiri muzinthu zamakono, monga zoumba zopangidwa ndi ceramic.silicon carbidezipangizo. Nanga maubwino asanu ndi limodzi otani a mumlengalenga kuthamanga sintering silicon carbide ndi ntchito silicon carbide ceramics?
Six ubwino wa mumlengalenga kuthamanga sinteredsilicon carbidezida:
1. Kutsika kochepa
Zida za silicon carbide zimakhala ndi kachulukidwe kakang'ono kuposa chitsulo, zomwe zimapangitsa chipangizocho kukhala chopepuka.
2. Kukana dzimbiri
Silicon carbidezinthu ali mkulu kusungunuka mfundo, inertia mankhwala, matenthedwe mantha kukana, pakachitsulo carbide ntchito abrasives, ceramic kilns, silicon carbide akusowekapo, angagwiritsidwe ntchito smelting ndi smelting makampani ndi ofukula yamphamvu distillation ng'anjo, njerwa, zotayidwa electrolytic cell akalowa, tungsten. , ng'anjo yaying'ono ndi zinthu zina za silicon carbide ceramic.
3, kutentha kwambiri, kuchuluka kwamafuta kumachepetsedwa
Silicon carbide zinthu amapangidwa pa kutentha kwambiri. M'malo ena otentha kwambiri, zida zomwe zimafunikira mphamvu yokonza ndikuwongolera bwino zomwe silicon carbide ceramics zitha kukwaniritsa zimafunikira. Kutentha kwakukulu kwa silicon carbide ndi pafupifupi 800, ndipo kutentha kwachitsulo ndi 250. Kuwerengera molakwika, pafupifupi kutentha kwapakati pa silicon carbide mumtundu wa 25 ~ 1400 ndi 4.10-6 / C. Kuchulukitsa kwamafuta a silicon carbide kumayesedwa, ndipo zotsatira zake zikuwonetsa kuti kuchuluka kwake ndi kocheperako kuposa ma abrasives ena ndi zida zotentha kwambiri. Sintered silicon carbide pansi pa mphamvu ya mumlengalenga
4, mkulu matenthedwe madutsidwe
Kutentha kwazinthu za silicon carbide ndizokwera kwambiri, chomwe ndi chinthu china chofunikira cha thupi la silicon carbide. Kutentha kwamafuta a silicon carbide ndikokulirapo kuposa kwa ma refractories ena ndi abrades, pafupifupi 4 nthawi ya corundum. Silicon carbide imakhala ndi coefficient yocheperako yakukulitsa kwamafuta komanso kutentha kwambiri, chifukwa chake chogwirira ntchito sichikhala ndi nkhawa yocheperako pakutentha ndi kuzizira. Ichi ndichifukwa chake zigawo za SiC zimagonjetsedwa kwambiri ndi mantha.
5, mphamvu zamakina apamwamba, kuuma bwino
Mphamvu zamakina za silicon carbide ndizokwera kwambiri, zomwe zimalepheretsa kusinthika kwazinthu. Silicon carbide ili ndi mphamvu zamakina apamwamba kuposa corundum.
6, kuuma kwakukulu ndi kukana kuvala
Kuuma kwa zida za silicon carbide ndizokwera kwambiri, ndipo kuuma kwa kusiyana kwa Moss ndi 9.2 ~ 9.6, chachiwiri kwa diamondi ndi tungsten carbide. Poyerekeza ndi zida zachitsulo zachitsulo, zimapereka kuuma kwakukulu, kutsika kocheperako kwa mikangano, kukangana kochepa, kuuma pang'ono pamwamba komanso kukana kuvala bwino popanda mafuta. Komanso, ndi kugonjetsedwa ndi zinthu zakunja, kusintha pamwamba kulolerana. Sintered silicon carbide pansi pa mphamvu ya mumlengalenga
Kugwiritsa ntchito mumlengalenga kuthamanga sintered silicon carbide ceramics
1, silicon carbide kupanga zinthu zadothi zapadera
Silicon carbide material ndi zinthu zolimba kwambiri komanso zotsika mtengo, zomwe zimatha kupanga zinthu za silicon carbide, monga silicon carbide seals, manja a silicon carbide, mbale za silicon carbide bulletproof, mbiri za silicon carbide, ndi zina zambiri, zomwe zingagwiritsidwe ntchito pazisindikizo zamakina ndi zina zambiri. mapampu osiyanasiyana. Sintered silicon carbide pansi pa mphamvu ya mumlengalenga
2, zirconia zopangira zida zadothi zapadera
Zirconia ceramic imakhala ndi ma ionic madulidwe apamwamba, kukhazikika kwamankhwala abwino komanso kukhazikika kwadongosolo, ndipo yakhala yophunzira komanso yogwiritsidwa ntchito kwambiri ndi electrolyte. Ndi kusintha njira kupanga zirconia zochokera electrolyte filimu, kuchepetsa kutentha ntchito ndi kupanga mtengo wa zipangizo zimenezi, ndi kuyesetsa kukwaniritsa mafakitale lilinso malangizo ofunika a kafukufuku mtsogolo.
