Kana zvasvika kune "ceramics", vanhu vazhinji vanotanga kufunga nezvemidziyo yemumba, midziyo yekushongedza - isina kusimba uye yakashata, inoratidzika isingabatanidzi ne "industry" kana "hardcore". Asi kune mhando yekeramic inotyora iyi inherent fungidziro. Kuomarara kwayo ndekwechipiri kune dhaimondi, uye inokwanisa kumirisana nekupisa kwakanyanya, kuramba corrosion, uye zvakare kuve insulated uye conductive, ichiva "inosiyana" mumunda weindasitiri. Zvirisilicon carbide ceramic.
Kubva pakupfeka-kusagadzikana kwemidziyo mumigodhi kusvika kumamodule emagetsi mumotokari nyowani dzesimba, kubva kune yakakwirira-yekushisa inodzivirira zvikamu muaerospace kusvika kumazuva ese emagetsi zvisimbiso, silicon carbide ceramics vari kutsigira chinyararire kushanda kwakanaka kwemaindasitiri mazhinji neayo akasiyana maitiro. Nhasi, ngatitaure nezve izvo zvinoita kuti iyi "inoshamisa" ceramic ive pachena.
1, Zvakaoma kune zvakanyanyisa: "mutakuri" mumunda wekuramba kupfeka
Iyo inonyanya kuzivikanwa mukana wesilicon carbide ceramics ndeyekupedzisira-yakakwirira kuoma uye kupfeka kuramba. Hukukutu hwayo hweMohs ndehwechipiri chete kune dhaimondi rakaomesesa muzvisikwa, rakaoma kudarika simbi yakajairwa, simbi isina tsvina, uye kunyange alumina ceramics.
Iyi' hardcore 'hunhu inoita kuti ipenye mumamiriro ezvinhu apo inoda kuramba kupfeka uye kubvaruka. Semuyenzaniso, mumigodhi uye maindasitiri esimbi, midziyo yekutakura slurry uye slag slurry (senge impellers yemapombi ane slurry pombi uye pombi liner) inowanzoshambidzwa neyakaoma mineral particles kwenguva yakareba, uye simbi dzakajairwa dzinokurumidza kukukurwa uye kubuda mvura. Zvikamu zvakagadzirwa nesilicon carbide ceramics zvinogona kumira nyore iyi "abrasion" uye kuve nehupenyu hwesevhisi kanoverengeka kana kunyange kanopfuura kagumi kune yezvikamu zvesimbi, zvichideredza zvakanyanya kuwanda uye mutengo wekutsiviwa kwemidziyo.
Kwete chete muzvirongwa zveindasitiri, isu tinogona zvakare kuona kuvepo kwayo muhupenyu hwezuva nezuva - senge silicon carbide friction pair mune mechaniki zvisimbiso. Nekupokana kwayo kwakanakisa kupfeka, inova nechokwadi chekuti midziyo haina kudonha uye ine kurasikirwa kwakaderera panguva yekumhanya-mhanya kutenderera, ichibvumira kushanda kwakadzikama kwemidziyo yakadai semapombi emvura uye compressors.
2, Superior "Resistance": Insulation yeKupisa Kwepamusoro uye Corrosion
Pamusoro pekuomarara, silicon carbide ceramics inewo yakanakisa kupisa tembiricha uye kusagadzikana nekuora, izvo zvinovabvumira "kunamatira kune yavo mbiru" munzvimbo dzakawanda dzakaomarara.
Panyaya yekudzivirira kwekushisa kwakanyanya, kunyangwe mushure mekushanda kwenguva refu pa1350 ℃, hapazove nekunyorova kana deformation. Chimiro ichi chinoita kuti ive "mudiwa" mune zvemuchadenga nemauto maindasitiri, akadai seanoshandiswa semuromo weroketi injini, lining kune yakakwirira-tembiricha mavira, etc. Inogona zvakananga kubata mukuru-tembiricha murazvo kana simbi yakanyungudutswa kuchengetedza kugadzikana. Mukugadzirwa kwepamusoro-tembiricha senge kilns yemaindasitiri uye metallurgical inoramba ichikanda, silicon carbide ceramic zvikamu zvinogona zvakare kutsiva simbi dzinokuvadzwa nyore nekupisa kwakanyanya, kuwedzera hupenyu hwemidziyo.
Panyaya yekurarisa kusagadzika, silicon carbide ceramics ine yakanyanya kusimba kugadzikana kwemakemikari. Ingave asidhi, alkali, kana magasi akasiyana-siyana anoparadza uye zvinwiwa, zvakaoma “kuzvibvisa”. Naizvozvo, muindasitiri yemakemikari, inowanzoshandiswa kugadzira lining yezvinoita midziyo, mapaipi uye mavharuvhu ekutakura corrosive media; Mumunda wekuchengetedzwa kwezvakatipoteredza, kuvapo kwayo kunogonawo kuonekwa mumidziyo yekurapa yakakwira acid-base wastewater, kuve nechokwadi chekuti michina haina kusvibiswa uye inoshanda zvakadzikama.
3, Yakasiyana-siyana "Kugona": A "Functional Master" anogona kuve akaomarara uye anochinjika.
Kana iwe uchifunga kuti silicon carbide ceramics inongova "yakaoma" uye "yakasimba", saka iwe unoikoshesa zvakanyanya. Zvinoenderana neakasiyana maitiro ekugadzirisa, inogona zvakare kuve neakawanda mabasa akadai se conductivity, insulation, uye thermal conductivity, zvichiita kuti ive chinhu chinoshanda chine akawanda mashandisiro.
-Conductivity uye semiconductor zvivakwa: Nekuita doping nezvimwe zvinhu, silicon carbide ceramics inogona kushandura kubva kune insulators kuenda kune conductor, uye kunyange kuva semiconductor zvinhu. Izvi zvinobvumira kuti iratidze unyanzvi hwayo mumunda wemagetsi emagetsi, zvakadai sekugadzira ma modules emagetsi emagetsi matsva emagetsi uye core components for traction converters muzvitima zvepamusoro. Kana ichienzaniswa neyechinyakare silicon zvinhu, silicon carbide semiconductors ine yakakwirira conductivity inoshanda uye yakaderera mashandisiro emagetsi, izvo zvinogona kuita kuti mota nyowani dzemagetsi dzichajise nekukurumidza uye dzive nehurefu hwakareba, uye zvakare kuita kuti midziyo yemagetsi ive diki uye inoshanda zvakanyanya.
-Yakanaka kupisa conductivity: Thermal conductivity yesilicon carbide ceramics inodarika iyo yeakajairwa ceramics, uye inotosvika iyo yemamwe simbi. Iyi ficha inoita kuti ive yakanakira kupisa kupisa zvinhu, semuenzaniso, mune yekupisa dissipate substrate yemwenje ye LED uye emagetsi machipisi, inogona kukurumidza kuburitsa kupisa kunze, kudzivirira michina kubva pakukuvadzwa nekuda kwekupisa, uye kugadzirisa hupenyu hwebasa nekugadzikana.
4, Pakupedzisira: Silicon carbide ceramics, iyo 'isingaoneki yekutyaira simba' yekusimudzira maindasitiri
Kubva ku "zvakaoma uye zvisingasviki" kusvika ku "high-temperature corrosion resistance", uyezve ku "multifunctionality", silicon carbide ceramics yakaputsa kunzwisisa kwevanhu pamusoro pemakeramiki echinyakare ane nhevedzano yezvivakwa zvakanakisa, zvichiva chinhu chakakosha chinotsigira kusimudzira kwekugadzirwa kwepamusoro, simba idzva, kuchengetedza simba uye kuchengetedza kwezvakatipoteredza. Izvo hazvina kujairika sesimbi kana kureruka sepurasitiki, asi mumamiriro eindasitiri anoda "kukunda matambudziko", inogara ichitsamira pane ayo "ane masimba ese" maitiro kuti ave simba guru mukugadzirisa matambudziko.
Nekuenderera mberi kwekufambira mberi kwetekinoroji, mutengo wekugadzira wesilicon carbide ceramics uri kuderera zvishoma nezvishoma, uye mamiriro ekushandisa ari kuramba achiwedzera. Mune ramangwana, ese ari maviri anoshanda akasimba emagetsi emagetsi emagetsi uye anogara akasimba maindasitiri emuchina anogona kuwedzera simba nekuda kwekuwedzera kwesilicon carbide ceramics. Rudzi urwu rwe "simba rose" rakavigwa muindasitiri riri kushandura chinyararire kugadzirwa kwedu nehupenyu.
