Silicon carbide ine simba rekupisa mumhepo haisisiri kungoshandiswa sechinhu chinogumbura chete, asi sechinhu chitsva, uye inoshandiswa zvakanyanya muzvigadzirwa zvetekinoroji yepamusoro, zvakaita seceramics zvakagadzirwa nezvinhu zvesilicon carbide. Saka ndeapi mabhenefiti matanhatu ekupisa mumhepo uye kushandiswa kwesilicon carbide ceramics?
Mabhenefiti matanhatu emidziyo yesimbi yesilicon carbide inodzvinyirirwa mumhepo:
1. Kuwanda kwakaderera
Zvinhu zvesilicon carbide zvine density yakaderera pane simbi, zvichiita kuti mudziyo uve wakareruka.
2. Kuramba ngura
Zvinhu zvesilicon carbide zvine mwero wekunyunguduka kwakanyanya, makemikari asina simba, zvinodzivirira kupisa, silicon carbide inoshandiswa muzvishandiso zvekubvoora, makilni eceramic, silicon carbide blanks, zvinogona kushandiswa muindasitiri yekunyungudutsa nekunyungudutsa ne vertical cylinder distillation furnace, zvidhinha, aluminium electrolytic cell lining, tungsten, small furnace nezvimwe zvigadzirwa zvesilicon carbide ceramic.
3, tembiricha yepamusoro, kuwedzera kwekupisa kunoderedzwa
Zvinhu zvesilicon carbide zvinogadzirwa pakupisa kwakanyanya. Mune dzimwe nzvimbo dzekupisa kwakanyanya, zvinhu zvinoda simba rekugadzirisa uye kunyatsogadzirisa zvinogona kuwanikwa nesilicon carbide ceramics zvinodiwa. Kupisa kwakanyanya kwesilicon carbide kunenge 800, uye tembiricha yesimbi i250 chete. Kuverenga kwakashata, avhareji yekuwedzera kwekupisa kwesilicon carbide iri pakati pe25 ~ 1400 i4.10-6 /C. Kuwedzerwa kwekupisa kwesilicon carbide kunoyerwa, uye mhedzisiro inoratidza kuti huwandu hwacho hudiki zvikuru pane hwezvimwe zvinhu zvinobvisa simba uye zvinhu zvinopisa zvakanyanya. Sintered silicon carbide pasi pekumanikidzwa kwemhepo.
4, kupisa kwakanyanya
Kufambiswa kwemafuta esilicon carbide kwakakwira, chinova chimwe chinhu chakakosha pamusoro pehunhu hwe silicon carbide. Kufambiswa kwemafuta esilicon carbide kwakakura zvikuru kupfuura kwemamwe ma refractories ne abrades, kanenge ka4 kupfuura corundum. Silicon carbide ine coefficient yakaderera yekuwedzera kwemafuta uye high thermal conductivity, saka workpiece ichasangana nekupisa kushoma panguva yekupisa nekutonhodza. Ndokusaka zvikamu zveSiC zvichinyanya kuramba kubatwa ne shock.
5, simba guru remakanika, kuomarara kwakanaka
Simba remuchina wesilicon carbide rakakwirira kwazvo, zvichidzivirira kushanduka kwezvinhu. Silicon carbide ine simba remuchina rakakwirira kupfuura corundum.
6, kuomarara kwakanyanya uye kuramba kupfeka
Kuomarara kwezvinhu zvesilicon carbide kwakanyanya, uye kuomarara kweMoss gap kuri 9.2 ~ 9.6, kuri kwechipiri kune diamond ne tungsten carbide. Kana tichienzanisa nezvinhu zvesimbi zvesimbi, zvinopa kuomarara kwakanyanya, coefficient yakaderera yekukweshana, kukweshana kwakaderera, kuomarara kudiki kwepamusoro uye kuramba kupfeka kwakanaka pasina mafuta. Pamusoro pezvo, inodzivirira zvinhu zvekunze, zvichivandudza kushivirira kwepamusoro. Sintered silicon carbide pasi pekumanikidzwa kwemhepo.
Kushandiswa kwesimbi yesimbi yesilicon carbide yakamanikidzwa mumhepo
1, kugadzirwa kwezvinhu zvesimbi zvesilicon carbide
Zvinhu zvesilicon carbide zvinhu zvine kuomarara kwakanyanya uye mutengo wakaderera, zvinogona kugadzira zvigadzirwa zvesilicon carbide, zvakaita sesilicon carbide seals, silicon carbide sleeves, silicon carbide bulletproof plates, silicon carbide profiles, nezvimwewo, zvinogona kushandiswa pazvisimbiso zvemakanika uye mapombi akasiyana-siyana. Sintered silicon carbide pasi pekumanikidzwa kwemhepo.
2, kugadzirwa kwezvinhu zvesimbi zvakakosha zve zirconia
Zirconia ceramic ine ionic conductivity yakakwira, kugadzikana kwakanaka kwemakemikari uye kugadzikana kwechimiro, uye yave chinhu chinodzidzwa zvakanyanya uye chinoshandiswa zvakanyanya. Nekuvandudza maitiro ekugadzira firimu re electrolyte rakavakirwa pa zirconia, kuderedza tembiricha yekushanda uye mutengo wekugadzira wezvinhu izvi, uye kuedza kuita maindasitiri zvakare inzira yakakosha yekutsvagisa mune ramangwana.
