Kusiyana pakati pa silicon carbide ceramics ndi silicon nitride ceramics

Mu gawo la zipangizo zamakono,silicon carbide (SiC) ndi silicon nitride (Si3N4) zoumbaumbaakhala awiri mwa mankhwala ofunikira kwambiri, chilichonse chili ndi makhalidwe apadera komanso ntchito zake. Kumvetsetsa kusiyana pakati pa zoumba ziwirizi ndikofunikira kwambiri m'mafakitale omwe amadalira zipangizo zogwirira ntchito kwambiri. Shandong Zhongpeng Special Ceramics Co., Ltd. ndi kampani yapamwamba kwambiri yomwe imapanga zoumba za silicon carbide, yomwe imagwira ntchito yofunika kwambiri pankhaniyi, imapereka chidziwitso chakuya pa makhalidwe ndi ntchito za zipangizozi.

Ma silicon carbide ceramics amadziwika ndi kuuma kwawo kwapadera komanso kukhazikika kwa kutentha. Amapangidwa ndi silicon ndi carbon, zomwe zimaphatikizana kuti zipange mankhwala omwe ali ndi kukana kuwonongeka komanso dzimbiri. Izi zimapangitsa kuti ma silicon carbide ceramics akhale abwino kwambiri kugwiritsidwa ntchito m'malo ovuta monga mafakitale a ndege, magalimoto ndi semiconductor. Silicon carbide yotenthetsera kwambiri imalolanso kuti ichotse kutentha bwino, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito kutentha kwambiri. Shandong Zhongpeng Special Ceramics Co., Ltd. imagwiritsa ntchito zinthuzi popanga ma silicon carbide ceramics apamwamba kwambiri omwe amakwaniritsa zosowa za mafakitale osiyanasiyana.

Koma, ma silicon nitride ceramics ali ndi mphamvu zabwino kwambiri zamakaniko, kuphatikizapo mphamvu zambiri komanso kulimba. Ma ceramics a Si3N4, opangidwa ndi silicon ndi nayitrogeni, amalimbana kwambiri ndi kutentha kwambiri ndipo ali ndi coefficient yotsika ya kutentha poyerekeza ndi silicon carbide. Izi zimapangitsa kuti ma silicon nitride ceramics akhale chisankho chabwino kwambiri pakugwiritsa ntchito zinthu zomwe zimafuna zipangizo kuti zipirire kusintha kwa kutentha mwachangu, monga ma turbine a gasi ndi zida zodulira. Kapangidwe kake kapadera ka Silicon nitride kamapatsanso kulimba kwabwino kwa kusweka, zomwe zimapangitsa kuti ikhale chinthu chosankhidwa kwambiri m'mafakitale omwe amafunikira zinthu zolimba.

Poyerekeza zinthu ziwirizi, kusiyana kwakukulu kuli mu mphamvu zawo zotenthetsera. Zomera za silicon carbide zimatha kupirira kutentha kwambiri kuposa zomera za silicon nitride, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito pa kutentha kwambiri. Komabe, kuthekera kwa silicon nitride kupirira kutentha kumapatsa mwayi m'malo omwe kutentha kumasinthasintha kwambiri. Kusiyana kumeneku ndikofunikira kwambiri kwa mainjiniya ndi opanga mapulani posankha zinthu zogwiritsidwa ntchito inayake, chifukwa kusankha zinthu kungakhudze kwambiri magwiridwe antchito ndi moyo wautumiki.

Kusiyana kwina kwakukulu pakati pa silicon carbide ndi silicon nitride ceramics ndi kukhazikika kwawo kwa mankhwala. Silicon carbide imapirira kwambiri ku okosijeni ndipo imatha kusunga mawonekedwe ake ngakhale m'malo omwe mankhwala amawononga. Izi zimapangitsa kuti ikhale yoyenera kwambiri pokonza mankhwala ndi ntchito zopangira semiconductor. Mosiyana ndi zimenezi, silicon nitride ceramics, ngakhale kuti imakhala yokhazikika pa mankhwala, singagwire bwino ntchito m'malo ena omwe amawononga. Kumvetsetsa makhalidwe a mankhwala amenewa ndikofunikira kwambiri m'mafakitale omwe amagwira ntchito m'mikhalidwe yovuta chifukwa kumakhudza kusankha zinthu ndi kapangidwe ka zinthu.

Njira zopangira silicon carbide ndi silicon nitride ceramics zimasiyananso kwambiri. Silicon carbide ceramics nthawi zambiri zimapangidwa ndi sintering, njira yomwe imaphatikizapo kutentha zinthuzo kutentha komwe kuli pansi pa malo ake osungunuka kuti zifike pokhuthala. Njirayi imatha kupanga mawonekedwe ovuta komanso zinthu zolemera kwambiri. Mosiyana ndi zimenezi, silicon nitride ceramics nthawi zambiri zimapangidwa pogwiritsa ntchito njira zopangira ufa ndi sintering, kuphatikizapo hot pressing kapena reaction bonding. Kusiyana kumeneku mu njira zopangira kungakhudze mawonekedwe omaliza a ceramic, kuphatikizapo microstructure yake ndi mawonekedwe ake a makina.

Ponena za mtengo, zoumba za silicon carbide nthawi zambiri zimakhala zodula kuposa zoumba za silicon nitride chifukwa cha zipangizo zopangira ndi ukadaulo wopangira. Komabe, magwiridwe antchito a silicon carbide kwa nthawi yayitali komanso kulimba kwake zitha kupangitsa kuti ndalama zoyambira zikhale zapamwamba, makamaka pakugwiritsa ntchito komwe kulephera kungayambitse ngozi zazikulu za nthawi yopuma kapena chitetezo. Shandong Zhongpeng Special Ceramics Co., Ltd. imayang'ana kwambiri pakupereka mayankho otsika mtengo popanda kuwononga khalidwe, kuonetsetsa kuti makasitomala akupeza phindu labwino kwambiri pa ndalama zomwe ayika mu zoumba za silicon carbide.

Mwachidule, kusiyana pakati pa silicon carbide ceramics ndi silicon nitride ceramics n'kofunika kwambiri ndipo kungakhudze kwambiri ntchito zawo m'mafakitale osiyanasiyana. Silicon carbide imachita bwino kwambiri m'malo otentha kwambiri komanso owononga mankhwala, pomwe silicon nitride imawonetsa kulimba kwambiri komanso kukana kutentha. Kumvetsetsa kusiyana kumeneku ndikofunikira kwambiri kwa mainjiniya ndi opanga posankha zipangizo zogwiritsira ntchito zinazake. Monga wopanga wamkulu wa silicon carbide ceramics, Shandong Zhongpeng Special Ceramics Co., Ltd. yadzipereka kupititsa patsogolo gawo la silicon carbide ceramics, kupereka zinthu zapamwamba zomwe zimakwaniritsa zosowa zamakampani amakono. Pogwiritsa ntchito mawonekedwe apadera a silicon carbide ndi silicon nitride, makampani amatha kukonza mapangidwe awo ndikuwongolera magwiridwe antchito azinthu zawo, pamapeto pake kuwonjezera magwiridwe antchito ndi kudalirika kwa ntchito zawo.
