Kupanikizika kwa mumlengalenga sintered silicon carbide sikungogwiritsidwanso ntchito ngati abrasive, koma ngati chinthu chatsopano, ndipo imagwiritsidwa ntchito kwambiri pazinthu zamakono, monga zitsulo zopangidwa ndi silicon carbide.Nanga maubwino asanu ndi limodzi otani a mumlengalenga kuthamanga sintering silicon carbide ndi ntchito silicon carbide ceramics?
Ubwino zisanu ndi chimodzi wa zinthu za mumlengalenga za sintered silicon carbide:
1. Kutsika kochepa
Zida za silicon carbide zimakhala ndi kachulukidwe kakang'ono kuposa chitsulo, zomwe zimapangitsa chipangizocho kukhala chopepuka.
2. Kukana dzimbiri
Silicon carbide zakuthupi zimakhala ndi malo osungunuka kwambiri, inertia yamankhwala, kukana kutenthedwa kwamafuta, silicon carbide imagwiritsidwa ntchito mu abrasives, mitsuko ya ceramic, zosowekapo za silicon carbide, zitha kugwiritsidwa ntchito pakusungunula ndi kusungunula ndi ng'anjo yowongoka ya silinda, njerwa, aluminium electrolytic cell lining. , 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'madera ena otentha kwambiri, zipangizo zomwe zimafuna mphamvu yokonza ndi kukonza bwino zomwe silicon carbide ceramics zingapeze zimafunika.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 ndiakulu kwambiri kuposa ma refractories ena ndi ma abrades, pafupifupi 4 nthawi ya corundum.Silicon carbide imakhala ndi coefficient yocheperako yakukulira kwamafuta komanso kukhathamiritsa kwamafuta ambiri, kotero chogwiriracho chizikhala ndi kupsinjika pang'ono 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 kocheperako, kuuma pang'ono kwapang'onopang'ono 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 ya 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 madutsidwe apamwamba, kukhazikika kwamankhwala abwino komanso kukhazikika kwadongosolo, ndipo yakhala yophunziridwa kwambiri ndikugwiritsa ntchito ma electrolyte.Ndi kusintha njira kupanga zirconia zochokera electrolyte filimu, kuchepetsa kutentha ntchito ndi kupanga mtengo wa zipangizo zimenezi, ndi kuyesetsa kukwaniritsa mafakitale ndi njira yofunika ya kafukufuku mtsogolo.
