Litšobotsi tsa carbide ea silicon e sintered reaction-sintered le ts'ebeliso ea mantlha? Carbide ea silicon e ka boela ea bitsoa carborundum kapa lehlabathe le sa cheng, ke motsoako o sa pheleng, o arotsoeng ka carbide e tala ea silicon le carbide e ntšo ea silicon e 'meli. Na u tseba litšobotsi le ts'ebeliso ea mantlha ea carbide ea silicon? Kajeno, re tla hlahisa litšobotsi le ts'ebeliso ea mantlha ea carbide ea silicon.
Carbide ea silicon e sebetsang hantle ke tšebeliso ea lehlabathe la quartz, coke ea petroleum e nang le calcined (kapa coking ea mashala), slag ea lehong (tlhahiso ea carbide ea silicon e tala e hloka ho eketsa letsoai la lijo) le lisebelisoa tse ling tse tala, ka ho qhibiliha ha mocheso o phahameng oa motlakase ka sebōpi se futhumatsang.
Litšobotsi tsa carbide ea silicon e sintered e nang le karabelo:
1. Ho tsamaisa mocheso le ho atolosa mocheso ha silicon carbide. Jwalo ka mofuta wa thepa e hanyetsang, setene se nang le carbon se na le kganyetso e ntle ya ho hanyetsa ho tshoha. Sena se bonahala haholo ka ho tsamaisa mocheso ka matla (ho fetisa mocheso) le ho tsamaisa mocheso ka tlase haholo.
2, ho tsamaisa motlakase ha silicon carbide. Silicon carbide ke thepa ea semiconductor, ho tsamaisa motlakase ha eona ho fapana ho latela mofuta le bongata ba litšila tse kenngoang ka har'a kristale, 'me khanyetso e bohareng ba 10-2-1012Ω·cm. Har'a tsona, aluminium, naetrojene le boron li na le tšusumetso e kholo ho tsamaisa motlakase ha silicon carbide, 'me ho tsamaisa motlakase ha silicon carbide e nang le aluminium e ngata ho eketseha haholo.
3. Khanyetso ea silicon carbide. Khanyetso ea silicon carbide e fetoha ka phetoho ea mocheso, empa ka har'a mocheso o itseng le litšobotsi tsa mocheso oa resistor ea tšepe lia fetoha. Kamano pakeng tsa khanyetso le mocheso oa silicon carbide e rarahane haholo. Ho khanna ha silicon carbide e sintered reaction-sinter hoa eketseha ka mocheso o nyolohang ho ea ho boleng bo itseng, 'me ho khanna ha silicon carbide hoa fokotseha ha mocheso o nyoloha hape.
Tšebeliso ea silicon carbide:
1, thepa e sa tsofaleng – e sebediswang haholoholo ho etsa lebili la lehlabathe, sandpaper e silang, lejwe la ho sila, lebili la ho sila, peista e silang le dihlahiswa tsa photovoltaic diseleng tsa photovoltaic, disele tsa photovoltaic le dikarolo tsa ho sila, ho sila le ho bentsha bokahodimo.
2, thepa e hanyetsang ea boleng bo holimo – e ka sebelisoa e le deoxidizer ea indasteri ea tšepe le thepa e hanelang mafome, ho etsa likarolo tse tsoelang pele tse entsoeng esale pele tsa ontong ea mocheso o phahameng, likarolo tse tsitsitseng, jj.
3, liseramike tse sebetsang – ha li fokotse feela bophahamo ba onto, empa hape li ntlafatsa boleng ba lihlahisoa tsa ontong ea indasteri, li fokotsa nako ea potoloho, ke thepa e loketseng e sa tobang bakeng sa ho sila glaze ea ceramic, liseramike tse sa fetoheng tse nang le mocheso o phahameng tse tsoelang pele, tse bonahatsang porcelain e sintered.
4, litšepe tse sa tloaelehang - likhoebo tsa tšepe le tšepe, tšimo ea indasteri ea tšepe, li na le ts'ebeliso e itseng.
5, tse ling - tse sebelisetsoang ho etsa lesela la mahlaseli a infrared kapa poleiti ea silicon carbide e omisang mahlaseli a infrared.
Silicon carbide ka lebaka la thepa ea eona e boreleli ea lik'hemik'hale tsa tlhaho, coefficient e phahameng ea phetisetso ea mocheso, coefficient e nyane ea katoloso e otlolohileng, khanyetso e ntle ea ho roala, ntle le lisebelisoa tse hanelang ho roala, ho na le ts'ebeliso e meng e meholo, joalo ka: ka ts'ebetso e ncha ea sekhomaretsi sa phofo ea silicon carbide ka har'a impeller ea centrifugal kapa cavity ea 'mele oa silindara, e ka ntlafatsa khanyetso ea ho roala le ho eketsa bophelo ba ts'ebeletso ba makhetlo a 1 ho isa ho a 2; E sebelisoa ho etsa thepa e hanyetsang ea boemo bo holimo, khanyetso ea ho tšoha ha mocheso o phahameng, boholo bo bonyenyane, boima bo bobebe le matla a phahameng, ts'ireletso ea tikoloho le phello ea ho boloka matla li totobetse. Silicon carbide ea boemo bo tlase (e nang le hoo e ka bang 85% SiC) ke moemeli o motle oa deoxidizing, o ka sebelisoang ho potlakisa sekhahla sa ho etsa tšepe, 'me o thusa ho laola sebopeho le ho ntlafatsa boleng ba tšepe. Ho feta moo, silicon carbide e boetse e sebelisoa ho etsa lisebelisoa tse ngata tsa ho futhumatsa tsa motlakase silicon molybdenum rod.
