Reaction-sintered silicon carbide zvivakwa uye mashandisiro makuru? Silicon carbide inogonawo kunzi carborundum kana jecha rinopisa moto, inorganic compound, yakakamurwa kuita green silicon carbide uye nhema silicon carbide mbiri. Iwe unoziva zvivakwa uye mashandisiro makuru esilicon carbide? Nhasi, tichasuma zvivakwa uye mashandisiro makuru esilicon carbide.
Reactive sintering silicon carbide iko kushandiswa kwejecha requartz, calcined petroleum coke (kana marasha coking), huni slag (kugadzirwa kwegirini silicon carbide inoda kuwedzera munyu wechikafu) uye zvimwe zvigadzirwa, kuburikidza nemagetsi ekudziya echoto chinoenderera kunyungudika.
Zvimiro zve reaction-sintered silicon carbide:
1. Thermal conductivity uye thermal yekuwedzera coefficient yesilicon carbide. Serudzi rwezvinhu zvinoramba, zvidhinha zvekabhoni zvine kupikisa kwakanyanya kuvhunduka. Izvi zvinonyanya kuratidzwa mune yayo yakasimba thermal conductivity (heat transfer coefficient) uye yakaderera coefficient of thermal kuwedzera.
2, iyo conductivity yesilicon carbide. Silicon carbide is semiconductor material, conductivity yayo inosiyana nemhando uye chiyero chetsvina yakaunzwa mucrystallization, uye kushorwa kuri pakati pe10-2-1012Ω · cm. Pakati pavo, aruminiyamu, nitrogen uye boron zvine simba guru pane conductivity yesilicon carbide, uye conductivity yesilicon carbide ine aluminium yakawanda inowedzera zvakanyanya.
3. Kupokana kwesilicon carbide. Kupokana kwesilicon carbide kunoshanduka nekushanduka kwetembiricha, asi mukati meimwe tembiricha renji uye tembiricha hunhu hwesimbi resistor hunodzoserwa shure. Hukama pakati pekupokana uye tembiricha yesilicon carbide yakanyanya kuoma. Iyo conductivity ye reaction-sintered silicon carbide inowedzera nekudziya kukwira kune imwe kukosha, uye conductivity inodzikira kana tembiricha yakwira zvakare.
Kushandiswa kwesilicon carbide:
1, zvinhu zvinodzivirira kupfeka - zvinonyanya kushandiswa kugadzira vhiri rejecha, kukuya sandpaper, whetstone, vhiri rekukuya, kugaya paste uye zvigadzirwa zve photovoltaic mumasero ephotovoltaic, masero ephotovoltaic uye zvikamu zvekukuya, kukuya uye kupukuta.
2, yakakwirira-yekupedzisira refractory zvinhu - inogona kushandiswa sesimbi yesimbi deoxidizer uye corrosion inodzivirira zvinhu, kugadzira inoenderera yakakwira tembiricha yehuni zvakagadzirirwa zvikamu, zvakagadziriswa zvikamu, nezvimwe.
3, maceramics anoshanda - kwete chete anogona kuderedza huwandu hwemoto, asi zvakare kuvandudza mhando yezvigadzirwa zvemaindasitiri, kuderedza kutenderera nguva, ndiyo yakakodzera isina kunanga zvinhu zveceramic glaze sintering, inoenderera tembiricha isina-oxide ceramics, inoratidza sintered porcelain.
4, zvisingawanzo simbi - mabhizinesi esimbi nesimbi, metallurgical industry concentrator field, vane imwe application.
5, imwe - inoshandiswa kugadzira kure-infrared nemwaranzi coating kana silicon carbide ndiro kure-infrared nemwaranzi dryer.
Silicon carbide nekuda kweyakatsetseka organic makemikari zvimiro, yakakwira kupisa coefficient, diki mutsara wekuwedzera coefficient, yakanaka kupfeka kuramba, pamusoro pekupfeka zvinhu zvinodzivirira, pane zvimwe zvinoshandiswa zvakanyanya, senge: nemaitiro matsva esilicon carbide poda glue mukati. iyo centrifugal impeller kana cylinder body cavity, inogona kuvandudza kupfeka kusagadzikana uye kuwedzera hupenyu hwebasa 1 kusvika 2 nguva; Inoshandiswa kugadzira yakakwira giredhi refractory zvinhu, yakakwira tembiricha yekuvhundutsa kuramba, saizi diki, huremu huremu uye simba rakakura, kuchengetedza kwezvakatipoteredza uye simba rekuchengetedza simba zviri pachena. Yakaderera-giredhi silicon carbide (ine inenge 85% SiC) yakanaka deoxidizing agent, inogona kushandiswa kumhanyisa simbi yekugadzira chiyero, uye inobatsira pakugadzirisa kuumbwa nekuvandudza kunaka kwesimbi. Uye zvakare, silicon carbide inoshandiswawo kugadzira akawanda emagetsi ekudziya zvinhu silicon molybdenum tsvimbo.
