Kusiyana pakati pa silicon carbide ceramics ndi silicon nitride ceramics

M'munda wa zida zapamwamba,silicon carbide (SiC) ndi silicon nitride (Si3N4) ceramicszakhala ziwiri mwazinthu zofunika kwambiri, chilichonse chili ndi zida zake komanso ntchito zake. Kumvetsetsa kusiyana pakati pa zitsulo ziwirizi ndizofunikira kwambiri kwa mafakitale omwe amadalira zipangizo zamakono. Shandong Zhongpeng Special Ceramics Co., Ltd. ndi bizinesi yapamwamba kwambiri yopanga zida za silicon carbide ceramics, yomwe imagwira ntchito yofunika kwambiri pamundawu, ikupereka zidziwitso zakuzama pazantchito ndikugwiritsa ntchito zidazi.

Silicon carbide ceramics amadziwika chifukwa cha kuuma kwawo kwapadera komanso kukhazikika kwamafuta. Amakhala ndi silicon ndi kaboni, zomwe zimaphatikizana kupanga gulu lomwe limavala bwino komanso kukana dzimbiri. Izi zimapangitsa silicon carbide ceramics kukhala yoyenera kugwiritsidwa ntchito m'malo ovuta monga mafakitale apamlengalenga, magalimoto ndi semiconductor. Kutentha kwapamwamba kwa Silicon carbide kumapangitsanso kuti isungunuke bwino kutentha, ndikupangitsa kuti ikhale yabwino pakugwiritsa ntchito kutentha kwambiri. Shandong Zhongpeng Special Ceramics Co., Ltd. amagwiritsa ntchito zinthuzi kupanga zoumba zapamwamba za silicon carbide zomwe zimakwaniritsa zosowa zamafakitale osiyanasiyana.

Komano, silicon nitride ceramics, ili ndi zida zabwino zamakina, kuphatikiza kulimba komanso kulimba mtima. Si3N4 ceramics, yopangidwa ndi silicon ndi nayitrogeni, imalimbana kwambiri ndi kutenthedwa kwa kutentha ndipo imakhala ndi gawo lochepa la kufalikira kwamafuta poyerekeza ndi silicon carbide. Izi zimapangitsa kuti silicon nitride ceramics kukhala chisankho chabwino kwambiri pazogwiritsa ntchito zomwe zimafunikira zida kuti zipirire kusintha kwa kutentha kwachangu, monga ma turbine a gasi ndi zida zodulira. Silicon nitride yapadera ya microstructure imapatsanso kulimba kwabwino kwambiri, ndikupangitsa kuti ikhale yosankha m'mafakitale omwe amafunikira zida zolimba.

Poyerekeza zida ziwirizi, chimodzi mwazosiyana kwambiri ndizomwe zimawotcha. Silicon carbide ceramics imatha kupirira kutentha kwambiri kuposa silicon nitride ceramics, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito potentha kwambiri. Komabe, kuthekera kwa silicon nitride kupirira kugwedezeka kwa kutentha kumapereka mwayi m'malo omwe kutentha kumasintha kwambiri. Kusiyanitsa kumeneku ndikofunikira kwa mainjiniya ndi okonza posankha zinthu zomwe zingagwiritsidwe ntchito mwanjira inayake, chifukwa kusankha kwa zinthu kumatha kukhudza kwambiri magwiridwe antchito ndi moyo wautumiki.

Kusiyana kwina kwakukulu pakati pa silicon carbide ndi silicon nitride ceramics ndikukhazikika kwawo kwamankhwala. Silicon carbide imagonjetsedwa kwambiri ndi okosijeni ndipo imatha kusunga katundu wake ngakhale m'malo owononga mankhwala. Izi zimapangitsa kuti zikhale zabwino popanga mankhwala komanso kupanga ma semiconductor. Mosiyana ndi izi, zoumba za silicon nitride, pomwe zimakhala zokhazikika, sizingagwire bwino m'malo ena owononga. Kumvetsetsa za mankhwalawa ndikofunikira kwambiri kwa mafakitale omwe akugwira ntchito m'malo ovuta chifukwa zimakhudza kusankha kwazinthu ndi kapangidwe kazinthu.

Njira zopangira silicon carbide ndi silicon nitride ceramics zimasiyananso kwambiri. Silicon carbide ceramics nthawi zambiri amapangidwa ndi sintering, njira yomwe imaphatikizapo kutenthetsa zinthuzo mpaka kutentha pansi pa malo ake osungunuka kuti akwaniritse kachulukidwe. Njirayi imatha kupanga mawonekedwe ovuta komanso zigawo zapamwamba kwambiri. Mosiyana ndi izi, zoumba za silicon nitride nthawi zambiri zimapangidwa pogwiritsa ntchito njira zophatikizira ufa ndi njira zopangira sintering, kuphatikiza kukanikiza kotentha kapena kugwirizanitsa. Kusiyanasiyana kwa njira zopangira izi kumatha kukhudza zomaliza za ceramic, kuphatikiza ma microstructure ndi makina ake.

Pankhani ya mtengo, zoumba za silicon carbide zimakhala zodula kuposa zoumba za silicon nitride chifukwa cha zopangira ndi ukadaulo wopangira. Komabe, kugwira ntchito kwanthawi yayitali komanso kulimba kwa silicon carbide kumatha kulungamitsa ndalama zoyambira, makamaka pamapulogalamu omwe kulephera kungayambitse kutsika kwakukulu kapena kuopsa kwachitetezo. Shandong Zhongpeng Special Ceramics Co., Ltd. imayang'ana kwambiri popereka mayankho otsika mtengo popanda kusokoneza mtundu, kuwonetsetsa kuti makasitomala amapeza phindu lalikulu pakugulitsa kwawo muzoumba za silicon carbide.

Mwachidule, kusiyana pakati pa zoumba za silicon carbide ceramics ndi silicon nitride ceramics ndizofunikira kwambiri ndipo zimatha kukhudza kwambiri ntchito zawo m'mafakitale osiyanasiyana. Silicon carbide imapambana kutentha kwambiri komanso malo owononga mankhwala, pomwe silicon nitride imawonetsa kulimba mtima komanso kukana kugwedezeka kwamafuta. Kumvetsetsa kusiyana kumeneku ndikofunikira kwa mainjiniya ndi opanga posankha zida zantchito zinazake. Monga mtsogoleri wotsogola wa silicon carbide ceramics, Shandong Zhongpeng Special Ceramics Co., Ltd. yadzipereka kupititsa patsogolo gawo lazoumba zotsogola, ndikupereka zinthu zapamwamba kwambiri zomwe zimakwaniritsa zosowa zamakampani amakono. Pogwiritsa ntchito mawonekedwe apadera a silicon carbide ndi silicon nitride, makampani amatha kukhathamiritsa mapangidwe awo ndikuwongolera magwiridwe antchito azinthu zawo, ndikuwonjezera mphamvu ndi kudalirika kwa ntchito zawo.
