Mu "nzvimbo yehondo inodziya zvakanyanya" yeindasitiri yemazuva ano, zvinhu zvesimbi zvechinyakare zvinowanzosangana nematambudziko akadai sekupfavisa, oxidation uye ngura. Uye rudzi rutsva rwezvinhu zvinonzisilicon carbide zvedongochinyararire iri kuva muchengeti mukuru wemidziyo inopisa zvakanyanya ine hunyanzvi hwayo hutatu hukuru hwe "kudzivirira kupisa kwakanyanya, kudzivirira kuvhunduka, uye kutamisa kupisa nekukurumidza".
1, Kukwanisa kwechokwadi kutsungirira tembiricha yakakwira
Zvigadzirwa zvesimbi zvesilicon carbide zvine simba rekudzivirira kupisa kwakanyanya. Maatomu azvo akabatana zvakasimba kuburikidza nezvisungo zvakasimba zve covalent, senge network ine mativi matatu yakarukwa kubva kusimbi, iyo inogona kuchengetedza chimiro chayo kunyangwe munzvimbo dzinopisa zvakanyanya dze1350 ℃. Hunhu uhwu hunoita kuti ikwanise kushanda kwenguva refu mukupisa kwakanyanya uko zvinhu zvesimbi zvisingagoni kutsungirira, zvichiita kuti ive sarudzo yakakodzera kuminda yakaita sehorning lining uye kuchengetedzwa kwekupisa kwemuchadenga.
2, 'Nhoo yekudzivirira' kubva mukuora kwe oxidative
Pasi pekumanikidzwa kaviri kwekupisa kwakanyanya uye ngura, zvinhu zvakajairika zvinowanzo bviswa jira nejira sesimbi yakaora. Pamusoro pesimbi dzesilicon carbide ceramics zvinogona kugadzira jira rakakora rekudzivirira resilicon dioxide, sekunge rinozvifukidza nezvombo zvisingaoneki. Iyi nzira ye "kuzviporesa" inoita kuti ikwanise kuramba kupisa kwakanyanya pa1350 ℃ uye kuramba kukurwa kubva mumunyu wakanyungudutswa, acid uye alkali. Inoramba ichichengetedza "pasina hupfu, hapana kudonha" munzvimbo dzakaoma dzakadai senzvimbo dzinopisa marara uye makemikari reactors.
3, 'Mutumwa' wekupisa
Kusiyana nehunhu hwe "kupisa uye hunyoro" hwezviumbwa zvesimbi, zviumbwa zvesimbi zvesilicon carbide zvine simba rekupisa rakafanana nesimbi. Zvakafanana nenzira yakavakirwa mukati mekupisa, iyo inogona kuendesa kupisa kwakaunganidzwa mukati memudziyo nekukurumidza kuenda kunze. Iyi nzira "isina kuvanza kupisa" inodzivirira kukuvara kwezvinhu kunokonzerwa nekupisa kwakanyanya kwenzvimbo, zvichiita kuti michina yekupisa kwakanyanya ishande zvakachengeteka uye isingashandise simba zvakanyanya.
Kubva kumaovheni emaindasitiri kusvika kumaovheni ekupisa e silicon wafer ane photovoltaic, kubva kumachubhu makuru emwaranzi kusvika kuma nozzles ane tembiricha yepamusoro, silicon carbide ceramics dziri kuchinja mamiriro etekinoroji eindasitiri ine tembiricha yepamusoro nemabhenefiti adzo akazara e "kugara kwenguva refu, kugadzikana, uye kutumirwa nekukurumidza". Semupi webasa retekinoroji akabatikana zvakanyanya nebasa re ceramics dzepamusoro, tinoramba tichikurudzira budiriro nekuvandudzwa mukushanda kwezvinhu, tichibvumira michina yakawanda yemaindasitiri kuchengetedza mamiriro ekushanda "akadzikama uye akadzikama" munzvimbo dzakaoma.
——Tichipfuura nepakati pemuganho wekupisa kwezvinhu, tinofamba nehunyanzvi!
