Silicon carbide ufa:

β-SiC ufa uli ndi kukhazikika kwamankhwala, kuuma kwakukulu, kutsika kwamafuta, kutsika kwamafuta owonjezera, kusiyana kwakukulu kwa band, kuthamanga kwa ma elekitironi, kuthamanga kwa ma elekitironi, mawonekedwe apadera a kutentha, etc., kotero ili ndi anti-kuvala, High kutentha kukana, kukana kutentha mantha, kukana dzimbiri, kukana ma radiation, zabwino theka-conductive katundu ndi katundu zina zabwino, chimagwiritsidwa ntchito zamagetsi, zambiri, mwatsatanetsatane processing luso, asilikali, zamlengalenga, zipangizo zapamwamba refractory, zipangizo zapadera ceramic, akupera patsogolo Zida ndi zida zolimbikitsira ndi magawo ena.Kagwiritsidwe ntchito kake kagawidwa makamaka m'magulu awa:

Ntchito yayikuluza SiC ufa:

1. Sintered ufa
β-SiC ili ndi chiyembekezo chogwiritsa ntchito kwambiri pamsika wazomera zadothi zapamwamba, zoumba zogwira ntchito komanso zida zapamwamba zokanira.Kuwonjezera β-SiC ku zinthu za ceramic za boron carbide kumatha kulimbitsa kulimba kwa chinthucho ndikuchepetsa kutentha kwa sintering, motero kumathandizira kwambiri magwiridwe antchito a ceramic carbide ceramics.
2. Zida zamagetsi
Monga semiconducting, β-SiC ndi yokwera kangapo kuposa α-Sic.Mphamvu ya anti-corona ya jenereta itatha kuwonjezera β-SiC ikuwonekera kwambiri, ndipo imakhalanso ndi kukana kwabwino kwa kuvala komanso kukana kutentha kwambiri.Zida zamagetsi zamagetsi, zowotchera, zotenthetsera kutentha, ndi zina zotero zopangidwa ndi β-SiC zimakhala ndi kutentha kwakukulu kwa kutentha, kutsekemera kwabwino kwa kutentha, ndi ntchito ya mankhwala ndi yabwino kwambiri kuposa zipangizo zina.
3. Kuphimba kwapadera
Chifukwa β-SiC ili ndi mawonekedwe a diamondi, tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono, tokhala ndi kukana kwamphamvu kwambiri, kukana kwa dzimbiri, matenthedwe apamwamba kwambiri, kukulitsa kocheperako, ndi zina zotere, kotero zimakhala ndi ntchito yabwino pazovala zapadera.
4. Kupera ndi kupukuta zipangizo
Monga pogaya ndi kupukuta mwatsatanetsatane, β-SiC ili ndi mphamvu yowonjezera yowonjezera kuposa white corundum ndi α-SiC, ndipo imatha kusintha kwambiri mapeto a mankhwala.
Β-SiC phala yopera, madzi opera, lamba wa nsalu ya emery wolondola kwambiri komanso zokutira zosamva kuvala zilinso ndi chiyembekezo chabwino chogwiritsa ntchito.
5. High-grade zapadera zowonjezera
Kuphatikizika kwa β-Sic ku zida zophatikizika za polima ndi zida zachitsulo kumatha kupititsa patsogolo matenthedwe awo, kuchepetsa kukulitsa, kukulitsa kukana kuvala, ndi zina zambiri, komanso chifukwa mphamvu yokoka ya β-SiC ndi yaying'ono, sikukhudza kulemera kwake. za zinthu.Kuchita kwa zida za nylon zamphamvu kwambiri, mapulasitiki apadera a engineering polyether ether ketone (PEEK), matayala a mphira, ndi mafuta opaka mafuta otsekemera amawonjezeredwa ku ultrafine β-SiC powder, ndipo ntchito yake ikuwonekera kwambiri.
6. Ntchito zina.
