Silicon nitride ceramic yokhala ndi thupi labwino kwambiri, mankhwala, komanso makina
Silicon nitride ceramics ali ndi zabwino kwambiri: kachulukidwe kochepa, kukana kutentha kwambiri, kudzipaka mafuta, kukana dzimbiri. Dense Si3N4zitsulo zadothi zimawonetsanso kulimba kwapang'onopang'ono, katundu wapamwamba wa modulus ndi kudzipangira mafuta, zomwe zingakhale bwino kukana mitundu yosiyanasiyana ya kuvala ndi kupirira malo ovuta omwe angapangitse zipangizo zina za ceramic kusweka, kupunduka kapena kugwa, kuphatikizapo kutentha kwakukulu, kusiyana kwakukulu kwa kutentha, ndi ultra-high vacuum.
Kugwiritsa Ntchito Kwakukulu Kwa Silicon Nitride Ceramics
Ukachenjede wazitsulo: Zoumba za silicon nitride zimakhala ndi kuuma kwakukulu, kukana kwamphamvu kwambiri komanso kukana dzimbiri, ndipo zimagwiritsidwa ntchito kwambiri m'magawo aukadaulo wamakina. Itha kugwiritsidwa ntchito popanga magawo monga mayendedwe, zisindikizo, zida zodulira ndi ma nozzles pa kutentha kwambiri komanso kuthamanga, kupereka magwiridwe antchito komanso moyo wautali.
Makampani opanga magalimoto: Chifukwa cha kukhazikika kwa kutentha komanso kukana kwa silicon nitride ceramics, imagwiritsidwa ntchito popanga zida zama injini zamagalimoto. Silicon nitride ceramics itha kugwiritsidwa ntchito popanga zida za injini zogwira ntchito kwambiri monga mphete za pisitoni, zomangira ma silinda ndi mavavu, zomwe zimathandizira kukonza bwino mafuta ndikuchepetsa kutulutsa mpweya.
Zamlengalenga: Kulemera kopepuka, kulimba kwamphamvu komanso kukana kutentha kwa silicon nitride ceramics kuwapanga kukhala zida zabwino zogwiritsira ntchito zakuthambo. Itha kugwiritsidwa ntchito popanga zida zazikulu monga zida za injini, masamba a turbine, zida zodzipatula zotenthetsera komanso chitetezo cham'mlengalenga kuti chikwaniritse zofunikira za kutentha kwambiri, kuthamanga kwambiri komanso malo owopsa.
Makampani a Chemical: Silicon nitride ceramics amagwiritsidwa ntchito kwambiri pamakampani opanga mankhwala chifukwa cha kukhazikika kwawo kwamankhwala komanso kukana dzimbiri. Silicon nitride ceramics itha kugwiritsidwa ntchito popanga zombo zotengera mankhwala, zonyamulira zonyamula, zida ndi mapaipi osamva asidi ndi alkali, ndipo zimatha kupirira zowononga zowononga komanso kutentha kwambiri.
Optoelectronics: Zoumba za silicon nitride zili ndi mawonekedwe abwino kwambiri owoneka bwino komanso amagetsi, motero zimakhala ndi ntchito zofunika kwambiri pankhani ya optoelectronics. Ikhoza kugwiritsidwa ntchito popanga kutentha kwakukulu ndi zowonjezera mphamvu zowonjezera zowonjezera mphamvu, ma lasers, zipangizo zoyankhulirana za kuwala ndi Windows optical ...
