Melemo e tšeletseng ea khatello ea sepakapaka sintered silicon carbide le ts'ebeliso ea silicon carbide ceramics.

Atmospheric pressure sintered silicon carbide ha e sa sebelisoa feela joalo ka abrasive, empa e le ntho e ncha, 'me e sebelisoa haholo lihlahisoa tsa theknoloji e phahameng, tse kang lirafshoa tse entsoeng ka thepa ea silicon carbide. Joale ke melemo efe e tšeletseng ea khatello ea sepakapaka sintering silicon carbide le ts'ebeliso ea silicon carbide ceramics?

Melemo e tšeletseng ea lisebelisoa tsa sepakapaka tsa silicon carbide:

1. Boima bo tlaase

Thepa ea silicon carbide e na le letsoalo le tlase ho feta tšepe, e etsang hore sesebelisoa se be bobebe.

2. Ho hanyetsa kutu

Silicon carbide e na le sebaka se phahameng sa ho qhibiliha, inertia ea lik'hemik'hale, ho hanyetsa mocheso oa mocheso, silicon carbide e sebelisoa ka li-abrasives, li-kilns tsa ceramic, likheo tsa silicon carbide, li ka sebelisoa indastering ea ho qhibilihisa le ho qhibilihisa ka sebōpi sa cylinder distillation, litene, aluminium electrolytic cell line. , tungsten, sebōpi se senyenyane le lihlahisoa tse ling tsa silicon carbide ceramic.

3, mocheso o phahameng, coefficient ea katoloso ea mocheso e fokotsehile

Lisebelisoa tsa silicon carbide li etsoa ka mocheso o phahameng. Libakeng tse ling tsa mocheso o phahameng, lisebelisoa tse hlokang matla a ho sebetsa le ho nepahala ha li-ceramics tsa silicon carbide li ka li finyella. Mocheso o phahameng oa silicon carbide ke hoo e ka bang 800, 'me mocheso oa tšepe ke 250 feela. Palo e thata, karolelano ea mocheso oa mocheso oa mocheso oa silicon carbide sebakeng sa 25 ~ 1400 ke 4.10-6 / C. Mocheso oa ho eketsa mocheso oa silicon carbide o lekantsoe, 'me liphetho li bontša hore chelete e nyenyane haholo ho feta ea li-abrasives tse ling le lisebelisoa tse phahameng tsa mocheso. Sintered silicon carbide tlas'a khatello ea sepakapaka

4, phahameng mogote conductivity

Thermal conductivity ea silicon carbide thepa e phahameng, e leng tšobotsi e 'ngoe ea bohlokoa ea thepa ea' mele ea silicon carbide. Thermal conductivity ea silicon carbide e kholo haholo ho feta ea li-refractories le li-abrades tse ling, hoo e ka bang makhetlo a 4 a corundum. Silicon carbide e na le coefficient e tlase ea katoloso ea mocheso le conductivity e phahameng ea mocheso, kahoo mosebetsi o tla ba tlas'a khatello e tlase ea mocheso nakong ea ho futhumatsa le ho pholile. Ke ka lebaka leo likarolo tsa SiC li hanyetsanang haholo le ho tsosoa.

5, matla a phahameng a mochine, ho satalla hantle

Matla a mochini a silicon carbide a phahame haholo, a thibela ho senyeha ha thepa. Silicon carbide e na le matla a phahameng a mochini ho feta corundum.

6, boima bo phahameng le ho roala ho hanyetsa

Ho thatafala ha thepa ea silicon carbide ho phahame haholo, 'me ho thatafala ha lekhalo la Moss ke 9.2 ~ 9.6, ea bobeli feela ho daemane le tungsten carbide. Ha e bapisoa le lisebelisoa tsa tšepe tsa tšepe, e fana ka boima bo phahameng, coefficient e tlase ea khohlano, khohlano e batlang e le tlase, ho hlaka ho hoholo ha holim'a metsi le ho hanyetsa ho apara hantle ntle le lubrication. Ho phaella moo, e hanyetsana le lintho tse ka ntle, ho ntlafatsa ho mamellana holimo. Sintered silicon carbide tlas'a khatello ea sepakapaka

Tšebeliso ea likhatello tsa sepakapaka sintered silicon carbide ceramics

1, tlhahiso ea thepa ea silicon carbide ea lirafshoa tse khethehileng

Silicon carbide material ke thepa e nang le boima bo phahameng le theko e tlase, e ka hlahisang lihlahisoa tsa silicon carbide, joalo ka silicon carbide seals, silicon carbide sleeves, silicon carbide bulletproof plates, silicon carbide profiles, joalo-joalo, e ka sebelisoang ho litiiso tsa mechine le lipompo tse fapaneng. Sintered silicon carbide tlas'a khatello ea sepakapaka

2, tlhahiso ea lisebelisoa tsa zirconia tsa ceramics tse khethehileng

Zirconia ceramic e na le conductivity e phahameng ea ionic, botsitso bo botle ba lik'hemik'hale le botsitso ba sebopeho, 'me e se e le lisebelisoa tsa electrolyte tse ithutoang ka ho pharaletseng le tse sebelisoang. Ka ho ntlafatsa ts'ebetso ea tlhahiso ea filimi ea electrolyte ea zirconia, ho fokotsa mocheso oa ho sebetsa le litšenyehelo tsa tlhahiso ea thepa ena, le ho loanela ho finyella indasteri e boetse e le tataiso ea bohlokoa ea lipatlisiso tsa nakong e tlang.
