Hunhu hwesilicon carbide inosanganiswa nereaction-sintered uye mashandisirwo makuru? Silicon carbide inogonawo kunzi carborundum kana jecha rinodzivirira moto, imusanganiswa wezvinhu zvisingasanganisike, wakakamurwa kuita green silicon carbide uye black silicon carbide two. Unoziva here hunhu hwesilicon carbide uye mashandisirwo makuru? Nhasi, tichazivisa hunhu hwesilicon carbide.
Reactive sintering silicon carbide imhando yekushandiswa kwejecha re quartz, calcined petroleum coke (kana coal coating), wood slag (kugadzirwa kwegreen silicon carbide kunoda kuwedzera munyu wekudya) nezvimwe zvinhu zvakagadzirwa, kuburikidza nemagetsi ekupisa vira rinopfungaira nekunyunguduka kwekupisa kwakanyanya.
Hunhu hwesilicon carbide inogadzirwa ne reaction-sintered:
1. Kufambiswa kwemafuta nekuwedzera kwemafuta kwesilicon carbide. Semhando yezvinhu zvinoramba kupisa, zvidhinha zvakakangwa zvine simba rekudzivirira kuvhunduka. Izvi zvinonyanya kuratidzwa nekufambiswa kwaro kwakasimba kwemafuta nekupisa (kupisa kunochinjisa) uye kuwedzera kwemafuta nekupisa kwakaderera.
2, kufambiswa kwesimbi kwesilicon carbide. Silicon carbide chinhu che semiconductor, kufambiswa kwayo kunosiyana zvichienderana nerudzi nehuwandu hwetsvina inounzwa mukristaro, uye resistance iri pakati pe 10-2-1012Ω·cm. Pakati pazvo, aruminiyamu, nitrogen ne boron zvine simba guru pakufambiswa kwesimbi kwesilicon carbide, uye kufambiswa kwesimbi kwesilicon carbide ine aruminiyamu yakawanda kunowedzera zvakanyanya.
3. Kuramba kwesilicon carbide. Kuramba kwesilicon carbide kunochinja nekuchinja kwetembiricha, asi mukati meimwe tembiricha uye hunhu hwetembiricha hwesimbi inodzoserwa shure. Hukama huripo pakati pekudzivirira netembiricha yesilicon carbide hwakaoma. Kufamba kwesimbi yesilicon carbide inosanganiswa ne reaction-sintered inowedzera netembiricha ichiwedzera kusvika kune imwe kukosha, uye kufamba kwesimbi kunoderera kana tembiricha ikakwira zvakare.
Kushandiswa kwesilicon carbide:
1, zvinhu zvisingapfeki - zvinonyanya kushandiswa kugadzira jecha vhiri, kukuya sandpaper, whetstone, grinding wheel, grinding paste uye zvigadzirwa zve photovoltaic mumasero e photovoltaic, masero e photovoltaic uye zvikamu zvekukuya pamusoro, kukuya nekupukuta.
2, zvinhu zvinodzivirira kupisa kwepamusoro-soro – zvinogona kushandiswa se deoxidizer yeindasitiri yesimbi uye zvinhu zvinodzivirira ngura, kugadzira zvinhu zvakagadzirwa nemoto wekupisa kwepamusoro-soro, zvikamu zvakagadzika, nezvimwewo.
3, zviumbwa zveceramic zvinoshanda - hazvingogone kuderedza huwandu hwechitofu chete, asiwo zvinovandudza mhando yezvigadzirwa zvechitofu zvemaindasitiri, kuderedza nguva yekutenderera, ndicho chinhu chakanakira chisina kunanga chekugadzira ceramic glaze, ceramics dzisiri dzeoxide dzinogara dzichipisa, dzichiratidza porcelain yakacheneswa.
4, simbi dzisingawanzoitiki - makambani esimbi nesimbi, munda wesimbi unobatanidza simbi, ane mamwe mashandisirwo.
5, zvimwe - zvinoshandiswa kugadzira chifukidziro chemwaranzi chiri kure kana kuti chinoshandiswa kugadzira chisimbiso chemwaranzi chiri kure.
Silicon carbide nekuda kwehunhu hwayo hwemakemikari eorganic akatsetseka, huwandu hwakawanda hwekupisa, huwandu hudiki hwekuwedzera kwemutsara, hunhu hwakanaka hwekupisa, pamusoro pezvinhu zvinodzivirira kupisa, kune mamwe mashandisirwo makuru, akadai se: nemaitiro matsva ekugadzira glue yeupfu yesilicon carbide mu centrifugal impeller kana cylinder body cavity, inogona kuvandudza hunhu hwekupisa uye kuwedzera hupenyu hwebasa ka1 kusvika kaviri; Inoshandiswa kugadzira zvinhu zvinodzivirira kupisa zvakanyanya, hunhu hudiki, huremu hushoma uye simba rakawanda, dziviriro yezvakatipoteredza uye simba rekuchengetedza simba zviri pachena. Silicon carbide yemhando yepasi (ine inenge 85% SiC) imushonga wakanaka wekubvisa oxidizing, unogona kushandiswa kukurumidzisa mwero wekugadzira simbi, uye unobatsira kugadzirisa maumbirwo uye kuvandudza mhando yesimbi. Pamusoro pezvo, silicon carbide inoshandiswawo kugadzira zvinhu zvakawanda zvemagetsi zvinopisa silicon molybdenum rod.
