Kana zvasvika kune "zviumbwa zvesimbi", vanhu vazhinji vanotanga vafunga nezvemidziyo yemumba, mavhasi ekushongedza - asina kusimba uye akapfava, anoita seasina hukama ne "indasitiri" kana "akaoma". Asi pane rudzi rwezviumbwa zvesimbi zvinoputsa pfungwa iyi. Kuoma kwayo kunotevera dhaimani chete, uye inogona kutsungirira tembiricha yakakwira, kuramba ngura, uye zvakare kuva ne insulation uye conductor, ichiva "inoshanduka-shanduka" mumunda wemaindasitiri. Ndiyosilicon carbide ceramic.
Kubva pamidziyo isingapfeki mumigodhi kusvika kumamodule emagetsi mumotokari itsva dzemagetsi, kubva kuzvinhu zvinodzivirira kupisa kwakanyanya mundege kusvika kumaseal emazuva ese emakanika, silicon carbide ceramics dziri kutsigira chinyararire mashandiro akanaka emaindasitiri mazhinji nehunhu hwadzo hwakasiyana. Nhasi, ngatitaurei nezve chinoita kuti iyi ceramic "inoshamisa" isiyane.
1、 Zvakaoma kusvika padanho repamusoro: "mutakuri" mumunda wekudzivirira kusakara
Chinhu chinonyanya kuzivikanwa nezve silicon carbide ceramics ndechekuti yakanyanya kuomarara uye haipfeki. Kuomarara kwayo kweMohs ndiko kunotevera dhaimani rakaomarara kupfuura dhaimani, kwakaoma kupfuura simbi yakajairika, simbi isina ngura, uye kunyange alumina ceramics.
Hunhu uhwu hwakaoma hunoiita kuti ipenye kana ichida kuramba kusakara. Semuenzaniso, mumaindasitiri emigodhi nesimbi, michina yekutakura tsvina netsvina (yakadai semaimpeller emapombi etsvina nemapaipi) inowanzo kusukwa nezvidimbu zvemineral zvakaoma kwenguva yakareba, uye simbi dzakajairika dzinokurumidza kupwanyika uye kudonhedza mvura. Zvikamu zvakagadzirwa nesilicon carbide ceramics zvinogona kutsungirira "kupwanyika" uku uye zvine hupenyu hwebasa kakawanda kana kupfuura kagumi pane zvikamu zvesimbi, zvichideredza zvakanyanya kuwanda uye mutengo wekutsiva michina.
Kwete mumaindasitiri chete, tinogonawo kuona kuvapo kwayo muhupenyu hwezuva nezuva - senge silicon carbide friction pair mu mechanical seals. Nekuramba kwayo kwakanaka kwekupfeka, inoita kuti michina isadonhe uye ine kurasikirwa kushoma panguva yekutenderera nekukurumidza, zvichibvumira kushanda kwakasimba kwemidziyo yakaita semapombi emvura nemacompressor.
2, "Kuramba" Kwepamusoro: Kudzivirira Kupisa Kwepamusoro uye Kuora
Pamusoro pekuomarara, simbi dzesilicon carbide dzinewo simba rekudzivirira kupisa kwakanyanya uye dzinodzivirira ngura, izvo zvinoita kuti dzikwanise "kunamatira pamatanda adzo" munzvimbo dzakawanda "dzakaoma".
Panyaya yekudzivirira kupisa kwakanyanya, kunyangwe mushure mekushanda kwenguva refu pa1350 ℃, hapazovi nekupfava kana kuchinja. Hunhu uhwu hunoiita "inodiwa" mumaindasitiri endege nemauto, akadai sekushandiswa semuromo wemainjini eroketi, lining yemaovheni anodziya zvakanyanya, nezvimwewo. Inogona kubata zvakananga marimi anodziya zvakanyanya kana simbi dzakanyungudutswa kuti irambe yakagadzikana. Mumaitiro ekugadzira kupisa kwakanyanya akadai semaovheni emaindasitiri uye metallurgical continuous casting, silicon carbide ceramic components inogonawo kutsiva simbi dzinokuvadzwa nyore nyore nekupisa kwakanyanya, zvichiita kuti michina irambe iripo.
Panyaya yekudzivirira ngura, silicon carbide ceramics ine kugadzikana kwakasimba kwemakemikari. Ingava acid, alkali, kana magasi akasiyana-siyana anoparadza uye zvinwiwa, zvakaoma "kuibvisa". Nokudaro, muindasitiri yemakemikari, inowanzoshandiswa kugadzira midziyo yekubatanidza, mapaipi nemavharuvhu ekutakura zvinhu zvinoparadza; Mukuchengetedza zvakatipoteredza, kuvapo kwayo kunogona kuonekwawo mumidziyo yekurapa mvura yakasviba ine acid-base yakawanda, zvichiita kuti michina isaparare uye ishande zvakanaka.
3、 "Kugona" Kunoshanda Nemhando Dzese: "Nyanzvi Inoshanda" inogona kuva yakaoma uye inochinjika
Kana uchifunga kuti simbi dzesilicon carbide dzakaoma uye "dzinogara kwenguva refu", saka unodzirerutsa zvakanyanya. Zvichienderana nehunyanzvi hwakasiyana hwekugadzirisa, dzinogonawo kuva nemabasa akasiyana-siyana akadai sekufambisa, kuputira, uye kufambisa kwekupisa, zvichiita kuti ive chinhu chinoshanda chine mashandisirwo akawanda.
-Hunhu hwekufambisa uye semiconductor: Nekushandisa zvimwe zvinhu, silicon carbide ceramics inogona kushanduka kubva pakuva insulators kuita conductors, uye kutoita semiconductor materials. Izvi zvinoibvumira kuratidza hunyanzvi hwayo mumunda wesimba remagetsi, zvakaita sekugadzira mamodule emagetsi emotokari itsva dzesimba uye zvikamu zvepakati zve traction converters muzvitima zvinomhanya zvakanyanya. Zvichienzaniswa nezvinhu zvechinyakare zvesilicon, silicon carbide semiconductors dzine conductivity yakakwira uye kushandiswa kwesimba kwakaderera, izvo zvinogona kuita kuti mota itsva dzesimba dzichaje nekukurumidza uye dzive nedaro refu, uye zvakare zvinoita kuti michina yemagetsi ive midiki uye inoshanda zvakanyanya.
-Kufambisa kwekupisa kwakanaka kwazvo: Kufambisa kwekupisa kwesilicon carbide ceramics kunodarika zvakanyanya kweceramics dzakajairika, uye kunotosvika kune dzimwe simbi. Chinhu ichi chinoita kuti ive chinhu chakakodzera chekuparadza kupisa, semuenzaniso, muchikamu chekupisa chemwenje yeLED nemachipisi emagetsi, inogona kukurumidza kubudisa kupisa, kudzivirira kukuvara kwemidziyo nekuda kwekupisa zvakanyanya, uye kuvandudza hupenyu hwebasa uye kugadzikana.
4, Pakupedzisira: Zviumbwa zvesimbi zvesilicon carbide, 'simba risingaonekwe rekusimudzira maindasitiri'
Kubva pa "zvakaoma uye zvinodzivirira kupera" kusvika pa "kupisa kwakanyanya", uyezve kusvika pa "mabasa akawanda", zviumbwa zve silicon carbide zvakakanganisa kunzwisisa kwevanhu nezvezviumbwa zvechinyakare zvine hunhu hwakanaka, zvichiva chinhu chakakosha chinotsigira kugadzirwa kwezvinhu zvepamusoro-soro, simba idzva, kuchengetedza simba uye kuchengetedzwa kwezvakatipoteredza. Hazviwanzoitiki sesimbi kana kuti zvakareruka sepurasitiki, asi mumaindasitiri anoda "kukunda matambudziko", zvinogara zvichivimba nehunhu hwazvo "hwemasimba ose" kuti zvive simba guru mukugadzirisa matambudziko.
Nekufambira mberi kuri kuita tekinoroji, mutengo wekugadzira silicon carbide ceramics uri kudzikira zvishoma nezvishoma, uye mamiriro ekushandisa ari kuramba achikura. Mune ramangwana, michina mitsva inoshanda zvakanaka uye michina yemaindasitiri inogara kwenguva refu inogona kuva nesimba nekuda kwekuwedzera silicon carbide ceramics. Rudzi urwu rwe "zvinhu zvine simba" zvakavanzwa muindasitiri zviri kuchinja chinyararire kugadzirwa kwedu nehupenyu hwedu.
