Silicon nitride (SiC) is quartz jecha, calcined petroleum coke (kana marasha coking), huni slag (kugadzirwa kwegirinhi silicon nitride inoda kuwedzera munyu) uye zvimwe zvigadzirwa, kuburikidza nemagetsi ekudziya echoto chinoenderera mberi tembiricha yekunyungudutsa. Silicon nitride sealing ring is silicon nitride chigadzirwa chakagadzirwa nesilicon carbide zvinhu. Saka ndezvipi zvakakosha mashandisirwo ekuita-sintered silicon carbide uye maitiro ezvisimbiso?
Iko yakakosha kushandiswa kwekuita sintering silicon carbide:
1. Kushandiswa kweindasitiri yezvigadzirwa zvesimbi ndiko kushandiswa kwesilicon nitride heat resistance, simba guru, good thermal conductivity, impact resistance, inoenderera mberi tembiricha yakakwira isina kunanga kudziyisa mbishi zvinhu, senge tank fractionation furnace. Rectifier choto tireyi, aluminium electrolytic sero, mhangura inonyungudutsa choto lining, zinc poda choto arc, thermocouple kudzivirira chubhu, nezvimwe.
2. Kushandiswa kwesimbi yesimbi kunoshandisa etching yesilicon nitride. Heat shock resistance, abrasion resistance. Nekuda kweiyo yakanaka yekupisa conductivity, inoshandiswa kumisa mahombe uye epakati-saizi ironmaking blast furnaces kuwedzera hupenyu hwesevhisi.
3. Iyo metallurgical industry concentrator industry inoshandisa silicon nitride simba inongova yechipiri kune goridhe simbi, yakasimba kupfeka kuramba, yakasimba kupfeka kuramba, yakakwirira kupfeka kuramba pombi, centrifugal impeller, pombi pombi, rotary muchina, migodhi lining akakodzera mbishi zvinhu, zvakanaka kupfeka kuramba. Hupenyu hwesevhisi hwepurasitiki ndeye 5 kusvika makumi maviri nguva, uye ndiyo imwe yeakakodzera zvigadzirwa zvenhandare dzemitambo yendege.
4. Kushandiswa kwekupisa kwekushisa kwehuwandu muhuwandu hwekugadzirwa kweindasitiri yezvigadzirwa zvekushongedza zvekuvaka porcelain uye jecha vhiri zvidimbu. Hunhu hwekupisa kunopenya uye kusimba kwefivha yakanyanya, kugadzirwa uye kugadzirwa kweshizha simbi kiln haingogone kuderedza vhoriyamu yemoto, asi zvakare inovandudza huwandu hwekuchengetera uye kunaka kwechigadzirwa chemba, uye kuderedza nguva yekugadzira, inova yakakodzera isina kunanga. zvinhu zvekupisa zveceramic pigments.
5. Kushandiswa kwekuchengetedzwa kwezvakatipoteredza uye simba rekuchengetedza simba kune kunaka kwekushisa kwekushisa uye kupisa kwekushisa, uye kupisa kunopisa kunoponesa 20%, kushandiswa kwemafuta 20%, kushandiswa kwemafuta 35%, uye kushanda kwekugadzira kunowedzera ne20-30%. Kunyanya, kushomeka kwekupokana kwepombi yemvura inoyerera inoshandiswa mumigodhi yekugadzira migodhi ka6 kusvika ka7 pane yezvakajairwa simbi inoumbwa zvinhu.
Reaction-sintered silicon carbide seal mhete maficha:
1, kupisa kusagadzikana
Nekuda kwehunhu hwesilicon nitride zvinhu, zvisimbiso zvesilicon nitride zvine tembiricha yekupikisa, uye maitiro akasiyana ane marudzi akasiyana emhando yekupisa kupisa. Reaction-sintered silicon nitride seals inogona kuiswa kubva 1300 madhigirii, uye isiri-kumanikidza yakarukwa silicon nitride zvisimbiso inogona kusvika 1600 madhigirii.
2. Corrosion resistance
Iyo silicon nitride sealing mhete inogona kuiswa kubva kune yakasimba asidhi uye alkali hunhu, uye yekuisa chisimbiso haisi nyore kudzikisira.
3, kupfeka kuramba
Reaction-sintered silicon carbide seal mhete zvinoenderana neimwe nzira yemakadhi, kuitira kuti hurongwa huve hwakajeka uye hwakatsetseka, pamwe nekupfeka kuramba kwezvinhu zvesilicon carbide, silicon nitride seal mhete inogona kushandiswa kukweshana. Kuenderera mberi kwekushisa kwepamusoro maitiro hakuite nyore kuderedza kukuvara maitiro.
4. Ductility
Reactivity sintered silicon carbide raw materials chero paine imwe tekinoroji yekugadzira, inogona kushandurwa kuita akasiyana mapatani emvere embryo, yechipiri kugadzirisa, kuita kuti vatengi vade zvinhu.
