Pankhani ya "ceramics", anthu ambiri amayamba kuganizira za mbale zapakhomo, miphika yokongoletsera - yosalimba komanso yosakhwima, yowoneka ngati yosagwirizana ndi "mafakitale" kapena "hardcore". Koma pali mtundu wina wa ceramic womwe umaphwanya malingaliro awa. Kuuma kwake ndi kwachiwiri kwa diamondi, ndipo imatha kupirira kutentha kwambiri, kukana dzimbiri, komanso kukhala insulated ndi conductive, kukhala "yosinthasintha" m'munda wa mafakitale. Zili chonchosilicon carbide ceramic.
Kuchokera pazida zosamva kuvala m'migodi kupita ku ma module amagetsi m'magalimoto atsopano amagetsi, kuchokera kuzinthu zothana ndi kutentha kwambiri mumlengalenga kupita ku zisindikizo zamakina amasiku onse, silicon carbide ceramics ikuthandizira mwakachetechete kugwira ntchito bwino kwa mafakitale ambiri ndi zinthu zawo zapadera. Lero, tiyeni tikambirane zomwe zimapangitsa kuti ceramic "yodabwitsa" ikhale yodziwika bwino.
1, Zovuta kwambiri: "chonyamulira" m'munda wa kukana kuvala
Ubwino wodziwika bwino wa silicon carbide ceramics ndi kuuma kwake kopitilira muyeso komanso kukana kuvala. Kulimba kwake kwa Mohs ndi kwachiwiri kwa diamondi yolimba kwambiri m'chilengedwe, yolimba kwambiri kuposa chitsulo wamba, chitsulo chosapanga dzimbiri, ngakhale zoumba za alumina.
Izi' hardcore 'makhalidwe zimapangitsa kuti ziwonekere pazochitika zomwe zimafunika kukana kutha. Mwachitsanzo, m'mafakitale amigodi ndi zitsulo, zida zonyamulira slurry ndi slag slurry (monga ma impellers a pampu slurry ndi zomangira mapaipi) nthawi zambiri zimatsukidwa ndi tinthu tating'ono tolimba kwa nthawi yayitali, ndipo zitsulo wamba zimakokoloka ndikutuluka madzi. Zigawo zopangidwa ndi silicon carbide ceramics zimatha kupirira mosavuta "abrasion" iyi ndikukhala ndi moyo wautumiki kangapo kapena kupitilira kakhumi kuposa zigawo zachitsulo, kuchepetsa kwambiri ma frequency ndi mtengo wa zida zosinthira.
Osati m'mafakitale okha, titha kuwonanso kupezeka kwake m'moyo watsiku ndi tsiku - monga ma silicon carbide friction pair mu zisindikizo zamakina. Ndi kukana kwake kovala bwino, zimatsimikizira kuti zidazo sizikudumphira ndipo zimakhala ndi zotayika pang'ono panthawi yozungulira kwambiri, zomwe zimapangitsa kuti zida zizigwira ntchito mokhazikika monga mapampu amadzi ndi compressor.
2, "Kutsutsa" Kwapamwamba: Kuteteza Kutentha Kwambiri ndi Kuwonongeka
Kuphatikiza pa kuuma, zoumba za silicon carbide zimakhalanso ndi kutentha kwapamwamba kwambiri komanso kukana dzimbiri, zomwe zimawalola "kumamatira ku nsanamira zawo" mu "malo ovuta" ambiri.
Pankhani ya kukana kutentha kwambiri, ngakhale pambuyo pogwira ntchito kwa nthawi yayitali pa 1350 ℃, sipadzakhala kufewetsa kapena kupunduka. Khalidweli limapangitsa kukhala "wokondedwa" m'mafakitale oyendetsa ndege ndi asilikali, monga momwe amagwiritsidwa ntchito ngati phokoso la injini za rocket, zopangira ng'anjo zotentha kwambiri, ndi zina zotero. Ikhoza kukhudzana mwachindunji ndi moto wotentha kwambiri kapena zitsulo zosungunuka kuti zikhalebe bata. Mu njira zopangira zotentha kwambiri monga ng'anjo zamafakitale ndi kuponyedwa kwazitsulo mosalekeza, zida za silicon carbide ceramic zitha kulowetsanso zitsulo zomwe zimawonongeka mosavuta ndi kutentha kwambiri, kukulitsa moyo wa zida.
Pankhani ya kukana dzimbiri, zoumba za silicon carbide zimakhala ndi kukhazikika kwamphamvu kwambiri kwamankhwala. Kaya ndi asidi, alkali, kapena mpweya wamitundumitundu wowononga ndi zamadzimadzi, ndizovuta kuti "tizikolopa". Choncho, m'makampani opanga mankhwala, nthawi zambiri amagwiritsidwa ntchito popanga ziwiya zotengera, mapaipi ndi ma valve kuti azinyamula zowononga zowonongeka; Pankhani yachitetezo cha chilengedwe, kupezeka kwake kumawonekeranso mu zida zochizira madzi otayira a acid-base, kuwonetsetsa kuti zidazo sizikuwonongeka komanso zimagwira ntchito mokhazikika.
3, "Luso" Losiyanasiyana: "Mbuye Wogwira Ntchito" yemwe amatha kukhala okhwima komanso osinthika
Ngati mukuganiza kuti zoumba za silicon carbide ndi "zolimba" komanso "zolimba", ndiye kuti mumazichepetsa kwambiri. Malinga ndi njira zosiyanasiyana zogwirira ntchito, imathanso kukhala ndi ntchito zingapo monga conductivity, insulation, ndi matenthedwe matenthedwe, ndikupangitsa kuti ikhale yogwira ntchito ndi ntchito zingapo.
-Conductivity ndi semiconductor properties: Pogwiritsira ntchito doping ndi zinthu zina, silicon carbide ceramics imatha kusintha kuchokera ku insulators kupita ku conductors, ndipo ngakhale kukhala zipangizo za semiconductor. Izi zimalola kuti awonetse luso lake pamagetsi amagetsi, monga kupanga ma modules amphamvu a magalimoto atsopano amphamvu ndi zigawo zikuluzikulu za otembenuza traction mu masitima othamanga kwambiri. Poyerekeza ndi zida zachikhalidwe za silicon, ma semiconductors a silicon carbide ali ndi magwiridwe antchito apamwamba komanso kugwiritsa ntchito mphamvu pang'ono, zomwe zimatha kupangitsa kuti magalimoto amagetsi atsopano azilipiritsa mwachangu komanso kukhala ndi nthawi yayitali, komanso kupanga zida zamagetsi kukhala zing'onozing'ono komanso zogwira mtima.
-Kutentha kwabwino kwambiri: Kutentha kwazitsulo za silicon carbide ceramics kumaposa kwambiri zadothi wamba, ndipo ngakhale kuyandikira kwa zitsulo zina. Mbaliyi imapangitsa kuti ikhale yabwino kwambiri yochepetsera kutentha, mwachitsanzo, mu gawo la kutentha kwa nyali za LED ndi tchipisi tamagetsi, imatha kutulutsa kutentha mwachangu, kuteteza zida kuti zisawonongeke chifukwa cha kutenthedwa, ndikuwongolera moyo wautumiki ndi bata.
4, Pomaliza: Silicon carbide ceramics, 'yosaoneka mphamvu yoyendetsa' pakukweza mafakitale
Kuchokera ku "zolimba ndi zosavala" mpaka "kukana kutentha kwa kutentha kwambiri", kenako "multifunctionality", silicon carbide ceramics yathyola kumvetsetsa kwa anthu za ceramics zachikhalidwe ndi mndandanda wa katundu wabwino kwambiri, kukhala chinthu chofunika kwambiri chomwe chimathandizira chitukuko cha mapangidwe apamwamba, mphamvu zatsopano, kuteteza mphamvu ndi kuteteza chilengedwe. Sizofala ngati zitsulo kapena zopepuka ngati pulasitiki, koma m'mafakitale omwe amafunikira "kugonjetsa zovuta", nthawi zonse amadalira makhalidwe ake "wamphamvuyonse" kuti akhale mphamvu yaikulu yothetsera mavuto.
Ndi kupita patsogolo kosalekeza kwaukadaulo, mtengo wopangira zoumba za silicon carbide ukuchepa pang'onopang'ono, ndipo mawonekedwe ogwiritsira ntchito akukulirakulirabe. M'tsogolomu, zida zatsopano zopangira mphamvu zatsopano komanso makina olimba amakampani amatha kukhala amphamvu kwambiri chifukwa chowonjezera zida za silicon carbide ceramics. Mtundu uwu wa "zinthu zamphamvu zonse" zobisika mumakampani zikusintha mwakachetechete kupanga ndi moyo wathu.
