Mu ukadaulo wamakono womwe ukukula mofulumira, kubuka kosalekeza kwa zipangizo zatsopano kwabweretsa kusintha kwakukulu m'mafakitale osiyanasiyana.Zoumbaumba zamakampani za Silicon CarbideMonga chinthu chogwira ntchito bwino, chikuchulukirachulukira pang'onopang'ono m'makampani amakono. Chifukwa cha magwiridwe antchito awo abwino komanso ntchito zosiyanasiyana, akhala chinthu chofunikira kwambiri chomwe chikutsogolera kupita patsogolo m'mafakitale osiyanasiyana.
1, Kodi silicon carbide ceramic yamakampani ndi chiyani?
Mwachidule, zinthu zomangira za silicon carbide za mafakitale ndi zinthu zomangira za ceramic zomwe zimapangidwa makamaka ndi silicon carbide (SiC). Silicon carbide yokha ndi chinthu chomwe chimapangidwa ndi silicon ndi carbon zomwe zimachitika kutentha kwambiri, ndipo kapangidwe kake kapadera ka atomu kamapatsa zinthuzo zinthu zabwino kwambiri.
Kuchokera pa kawonedwe ka microscopic, kapangidwe ka kristalo ka silicon carbide ndi kakang'ono, ndipo ma chemical bond pakati pa ma atomu ndi olimba, zomwe zimapangitsa kuti silicon carbide ceramics ikhale yolimba komanso yokhazikika. Poyerekeza ndi zipangizo zachikhalidwe zachitsulo, silicon carbide ceramics zamafakitale sizipangidwa ndi ma atomu achitsulo olumikizidwa ndi ma bond achitsulo; Mosiyana ndi zipangizo wamba za organic polymer, sizipangidwa ndi maunyolo obwerezabwereza a organic molecular. Ndi mtundu watsopano wa zinthu zopanda organic zomwe zimapangidwa ndi sintering silicon carbide powder pansi pa kutentha kwambiri komanso kupanikizika kwakukulu kudzera mu njira yapadera yokonzekera ceramic.
2、 Kuwonetsa Kuchita Bwino Kwambiri
1. Kuuma kwambiri, kukana kuvala komanso kukana kuvala
Kuuma kwa zoumba za silicon carbide zamafakitale ndi kwakukulu kwambiri, kwachiwiri kuposa diamondi. Khalidweli limapangitsa kuti zikhale zabwino kwambiri pankhani yokana kukalamba. Tangoganizirani za makina opangira zinthu, zida zodulira ziyenera kukhudzana ndi zinthu zosiyanasiyana zachitsulo kuti zidulidwe. Ngati zidazo sizikukalamba mokwanira, zidzatha msanga ndikukhala zosalimba, zomwe zimakhudza kulondola kwa makina ndi magwiridwe antchito. Zida zodulira zopangidwa ndi zoumba za silicon carbide zamafakitale, zomwe zimakhala zolimba kwambiri, zimatha kukhala zowala kwa nthawi yayitali, zomwe zimapangitsa kuti ntchito yokonza zinthu izi ikhale yabwino komanso kuchepetsa ndalama zopangira.
2. Kukana kutentha kwambiri, kokhazikika komanso kodalirika
Zida za silicon carbide zamakampani zimakhala ndi kukana kutentha kwambiri. M'malo otentha kwambiri, zinthu zambiri zimafewa, kusinthika, komanso kusungunuka, pomwe zida za silicon carbide zimatha kusunga zinthu zakuthupi komanso zamakemikolo zokhazikika pa kutentha kwakukulu. Mwachitsanzo, m'zitofu zotentha kwambiri mumakampani opanga zitsulo, ndikofunikira kugwiritsa ntchito zipangizo zomwe zimatha kupirira kutentha kwambiri kuti zipange zophimba ng'anjo, zophimba, ndi zina. Zida za silicon carbide zamakampani zimatha kugwira ntchito imeneyi, kuonetsetsa kuti ng'anjo yotentha kwambiri ikugwira ntchito bwino komanso kukulitsa moyo wa ntchito ya zidazo.
3. Kukhazikika kwabwino kwa mankhwala
Kaya akukumana ndi mankhwala owononga monga ma asidi amphamvu kapena maziko, ma silicon carbide ceramics amawagwiritsa ntchito mofatsa. Pakupanga mankhwala, nthawi zambiri pamafunika kugwiritsa ntchito zinthu zosiyanasiyana zopangira mankhwala owononga kwambiri, ndipo zotengera ndi mapaipi omwe amagwiritsidwa ntchito kusunga ndi kunyamula zinthuzi amafunika kukana dzimbiri kwambiri kwa zinthuzo. Ma silicon carbide ceramics amafakitale, omwe ali ndi kukhazikika kwabwino kwa mankhwala, akhala chinthu chabwino kwambiri chopangira zotengera ndi mapaipi awa, popewa zoopsa zachitetezo monga kutayikira komwe kumachitika chifukwa cha dzimbiri.
4. Kutentha kwabwino kwambiri
Ma ceramic a mafakitale a silicon carbide ali ndi mphamvu yabwino kwambiri yotenthetsera kutentha ndipo amatha kutentha mwachangu. Kagwiridwe kake kamakhala ndi ntchito zofunika kwambiri pazochitika zomwe zimafuna kutentha koyenera, monga zida zina zogwiritsira ntchito kutentha kwambiri, komwe kutentha kwambiri kungakhudze ntchito yanthawi zonse. Zigawo zotenthetsera kutentha zopangidwa ndi ma ceramic a mafakitale a silicon carbide zimatha kutulutsa kutentha mwachangu, ndikutsimikizira kuti zidazo zikugwira ntchito bwino.
3, minda yogwiritsidwa ntchito kwambiri
1. Kupanga makina
Mu makampani opanga makina, zoumba za silicon carbide zamafakitale zimagwiritsidwa ntchito popanga zinthu zosiyanasiyana zosatha monga ma bearing, mphete zotsekera, zida zodulira, ndi zina zotero. Poyerekeza ndi ma bearing achitsulo achikhalidwe, ma bearing a silicon carbide ceramic ali ndi kuuma kwakukulu komanso kukana kuvala, ndipo amatha kugwira ntchito mokhazikika pansi pa mikhalidwe yovuta monga liwiro lalikulu komanso kutentha kwambiri, zomwe zimapangitsa kuti magwiridwe antchito ndi kudalirika kwa zida zamakaniko zigwire ntchito bwino.
2. Kugulitsa zitsulo m'migodi
Malo omwe amagwiritsidwa ntchito popanga zitsulo m'migodi nthawi zambiri amakhala ovuta, ndipo zida zimayesedwa kangapo monga kutha, kutentha kwambiri, ndi dzimbiri. Zida zadothi za silicon carbide, zomwe zimakhala ndi kukana kwambiri kutha, zingagwiritsidwe ntchito popanga mbale zamkati zogwiritsira ntchito zida zophwanyira migodi ndi zigawo zosatha kutha kwa ma roller a zitsulo. Panthawi yophwanya miyala, mbale zamkati za ceramic zimatha kukana kukhudzidwa kwakukulu ndi kukangana kwa miyala, ndikuwonjezera nthawi yosinthira zidazo; Mu njira yachitsulo, yomwe ikukumana ndi kuwonongeka kwa kusungunuka kwa kutentha kwambiri, zida zadothi za silicon carbide zimathanso kukhala zokhazikika, kuonetsetsa kuti kupanga zitsulo kukupita patsogolo.
3. Kuchotsa sulfure m'mafakitale
Mu ndondomeko yochotsa sulfure m'mafakitale, mpweya wowononga ndi zakumwa zokhala ndi sulfure zimakhudzidwa, zomwe zimafuna kukana dzimbiri kwambiri kwa zipangizozi. Zida za silicon carbide za mafakitale zakhala zinthu zabwino kwambiri zochotsera sulfure chifukwa cha kukhazikika kwawo kwabwino kwa mankhwala. Mwachitsanzo, ma nozzle opopera, mapaipi ndi zinthu zina zomwe zili mu nsanja yochotsera sulfure zimapangidwa ndi zida za silicon carbide, zomwe zimatha kukana dzimbiri la ma ayoni a sulfure, kuchepetsa kulephera kwa zida, kuonetsetsa kuti dongosolo lochotsera sulfure likugwira ntchito bwino, komanso kuthandiza mabizinesi kukwaniritsa miyezo ya chilengedwe.
Zoumba za silicon carbide za mafakitale zikukhala chinthu chofunikira kwambiri komanso chofunikira kwambiri m'makampani amakono chifukwa cha mawonekedwe awo apadera komanso malo ogwiritsidwa ntchito kwambiri. Ndikukhulupirira kuti posachedwa, zidzawonetsa kuthekera kwakukulu m'magawo ambiri ndikupereka zopereka zazikulu pakukweza chikhalidwe cha anthu.
