Izinzuzo eziyisithupha ze-silicon carbide ecindezelwe umoya kanye nokusetshenziswa kwe-silicon carbide ceramics

I-silicon carbide ecindezelwe umoya ayisasetshenziswa nje njengento yokukhuhla, kodwa njengento entsha, futhi isetshenziswa kabanzi emikhiqizweni yobuchwepheshe obuphezulu, njenge-ceramics ezenziwe ngezinto ze-silicon carbide. Ngakho-ke yiziphi izinzuzo eziyisithupha zokusebenzisa i-silicon carbide ecindezelwe umoya kanye nokusetshenziswa kwe-silicon carbide ceramics?

Izinzuzo eziyisithupha zezinto zokwakha ze-silicon carbide ezicindezelwe umoya:

1. Ukuminyana okuphansi

Izinto ze-silicon carbide zinobukhulu obuphansi kunensimbi, okwenza idivayisi ibe lula.

2. Ukumelana nokugqwala

Izinto ze-silicon carbide zinendawo yokuncibilika ephezulu, i-inertia yamakhemikhali, ukumelana nokushaqeka kokushisa, i-silicon carbide isetshenziswa ezintweni zokubhula, ama-oven e-ceramic, ama-blank e-silicon carbide, ingasetshenziswa embonini yokuncibilikisa kanye nokuncibilikisa nge-vertical cylinder distillation furnace, izitini, i-aluminium electrolytic cell lining, i-tungsten, i-small furnace kanye neminye imikhiqizo ye-silicon carbide ceramic.

3, izinga lokushisa eliphezulu, i-coefficient yokwanda kokushisa iyancipha

Izinto ze-silicon carbide zenziwa emazingeni okushisa aphezulu. Kwezinye izindawo zokushisa okuphezulu, izinto ezidinga amandla okucubungula kanye nokunemba kokucubungula okungafinyelelwa yi-silicon carbide ceramics. Izinga lokushisa eliphezulu le-silicon carbide lingaba ngu-800, kanti izinga lokushisa lensimbi lingama-250 kuphela. Ukubalwa okungenangqondo, isilinganiso sokwanda kokushisa kwe-silicon carbide esiphakathi kuka-25 ~ 1400 singu-4.10-6 /C. I-coefficient yokwanda kokushisa kwe-silicon carbide iyalinganiswa, futhi imiphumela ikhombisa ukuthi inani lincane kakhulu kunezinye izinto ezisusayo nezinto zokushisa okuphezulu. I-silicon carbide eqoshiwe ngaphansi kwengcindezi yomoya

4, ukuhanjiswa okuphezulu kokushisa

Ukushisa kwezinto ze-silicon carbide kuphakeme, okungenye isici esibalulekile sezakhiwo zomzimba ze-silicon carbide. Ukushisa kwe-silicon carbide kukhulu kakhulu kunokwezinye izinto eziphikisayo kanye nama-abrades, cishe izikhathi ezine kune-corundum. I-Silicon carbide ine-coefficient ephansi yokwanda kokushisa kanye nokushisa okuphezulu, ngakho-ke umsebenzi uzobhekana nokucindezeleka okuncane kokushisa ngesikhathi sokushisa nokupholisa. Yingakho izingxenye ze-SiC zimelana kakhulu nokushaqeka.

5, amandla aphezulu okusebenza ngomshini, ukuqina okuhle

Amandla okusebenza kwezinto ze-silicon carbide aphezulu kakhulu, okuvimbela ukuguquguquka kwezinto. I-Silicon carbide inamandla okusebenza aphezulu kune-corundum.

6, ubulukhuni obuphezulu kanye nokumelana nokuguguleka

Ubulukhuni bezinto ze-silicon carbide buphezulu kakhulu, kanti ubulukhuni be-Moss gap bungu-9.2 ~ 9.6, okwesibili kuphela ngemuva kwe-diamond ne-tungsten carbide. Uma kuqhathaniswa nezinto zensimbi zensimbi, inikeza ubulukhuni obuphezulu, i-coefficient ephansi yokungqubuzana, ukungqubuzana okuphansi, ubulukhuni obuncane bomphezulu kanye nokumelana okuhle kokuguguleka ngaphandle kokugcoba. Ngaphezu kwalokho, imelana nezinto zangaphandle, ithuthukisa ukubekezelelana komphezulu. I-silicon carbide ehlanganisiwe ngaphansi kwengcindezi yomoya

Ukusetshenziswa kwe-silicon carbide ceramics ecindezelwe umoya

1, ukukhiqizwa kwezinto ze-silicon carbide zezinto zobumba ezikhethekile

Izinto ze-silicon carbide ziwuhlobo olunobulukhuni obuphezulu kanye nezindleko eziphansi, ezingakhiqiza imikhiqizo ye-silicon carbide, njengezimbozo ze-silicon carbide, imikhono ye-silicon carbide, amapuleti angenazinhlamvu ze-silicon carbide, amaphrofayili e-silicon carbide, njll., ezingasetshenziswa ezimbozweni zemishini kanye namaphampu ahlukahlukene. I-silicon carbide e-Sintered ngaphansi kwengcindezi yomoya

2, ukukhiqizwa kwezinto ze-zirconia zezinto zobumba ezikhethekile

I-Zirconia ceramic ine-ionic conductivity ephezulu, ukuzinza okuhle kwamakhemikhali kanye nokuqina kwesakhiwo, futhi isibe yinto efundwa kabanzi futhi esetshenziswa kakhulu ye-electrolyte. Ngokuthuthukisa inqubo yokukhiqiza ifilimu ye-electrolyte esekelwe ku-zirconia, ukunciphisa izinga lokushisa lokusebenza kanye nezindleko zokukhiqiza zalezi zinto, kanye nokulwela ukufeza izimboni nakho kuyisiqondiso esibalulekile socwaningo lwesikhathi esizayo.
