Mundima yemaindasitiri uko tembiricha yakakwira, ngura, uye mamiriro ekushanda akanyanya kuitika, zvinhu zvechinyakare zvinowanzo kuve zvisina kukwana. Semutungamiri mu tekinoroji yesimbi yesilicon carbide ceramic, tinoziva zvakanaka kuti zvinhu izvi zvinoshandura sei miganhu yetekinoroji yekuchinjana kupisa. Chinyorwa chino chichakutungamira kuti unzwisise chikonzero neizvinhu zvinochinja-chinja kupisa zvesilicon carbidevave "vanhu vakakwana" munzvimbo dzakaoma.
Mabhenefiti mana makuru eSilicon Carbide
Silicon carbide (SiC) chinhu chemhando yepamusoro checeramic chakagadzirwa nenzira yekugadzira, uye musanganiswa wayo wakasiyana wehunhu hwayo unoita kuti ive sarudzo yakakodzera yemidziyo yekuchinjana kupisa mumamiriro ekushanda akaomarara.
1. Kufambisa kwakanaka kwazvo kwekupisa
Kushanda zvakanaka kwesilicon carbide pakupisa kunodarika kushanda kwezvinhu zvesimbi zvakaita sesimbi isingatsvi, uye inogona kukurumidza kutamisa kupisa mumamiriro ekupisa kwakanyanya, zvichivandudza zvakanyanya kushandiswa kwesimba uku ichideredza huwandu hwemidziyo.
2. Kusatya kupisa kwakanyanya
Zvinhu zvesimbi zvinogona kupfava uye kuchinja kana tembiricha yakakwira ikaramba iripo, nepo silicon carbide ichigona kuchengetedza kugadzikana kwechimiro munzvimbo dziri pamusoro pe1350 ° C, zvichiita kuti ive mubatsiri akavimbika kwenguva refu wemidziyo yakaita semakiln anodziya zvakanyanya uye machemical reactors.
3. Nyanzvi yezvechisikigo mukudzivirira ngura
Ingave iri munzvimbo dzine ngura dzakadai semaacid akasimba kana nzvimbo dzine munyu wakawanda, ganda rekuchengetedza oxide rinongoerekana raumbwa pamusoro pesilicon carbide kudzivirira kukurwa kwemakemikari uye kuderedza zvakanyanya nguva yekuchengetedza.
Chinangwa chemaitiro ekuita sintering
Tekinoroji yedu huru, reaction sintered silicon carbide (RBSC), inogadzira zvinhu zveceramic zvakakora uye zvakafanana nekuisa zvinhu zvesilicon mu "porous carbon matrix". Kubudirira uku kwetekinoroji kunounza mabhenefiti matatu makuru:
-Deredza kushaya simba kunokonzerwa nemapores emukati mune zvinhu zvechinyakare zvakapiswa
-Kunyora nemazvo magadzirirwo akaomarara enzira dzekuyerera kuti uvandudze kushanda zvakanaka kwekutamisa kupisa
-Kuenzanisa kushanda kwepamusoro uye kudzora mutengo
Kugadzikana kwenguva refu, kudzikiswa kwemitengo muhupenyu hwese
Kugara uchichinja zvinhu zvesimbi zvechinyakare nekuda kwengura uye kukura kwava nhoroondo. Kugara kwenguva refu kwezvinhu zvesilicon carbide kunoita kuti zvive nyore kushanda panguva yekuisa michina, zvichiramba zvichigadzira kukosha muhupenyu hwese hwemidziyo.
Semunhu mutsva anonyanya kugadzira silicon carbide inogadzirwa ne reactive sintered kwemakore anopfuura makumi maviri,Shandong Zhongpengyagara yakazvipira kupa mhinduro dzekutarisira kupisa dzakagadzirirwa vatengi. Kunyangwe muchida kugadzirisa masisitimu aripo kana kugadzira michina mitsva, timu yedu ichakubatsirai kuburitsa mukana wakazara wezvinhu zvesilicon carbide.
