Izinzuzo eziyisithupha ze-atmospheric pressure sintered silicon carbide kanye nokusetshenziswa kwe-silicon carbide ceramics

I-atmospheric pressure sintered silicon carbide ayisasetshenziswa nje njenge-abrasive, kodwa kakhulu njengento entsha, futhi isetshenziswa kakhulu emikhiqizweni yobuchwepheshe obuphezulu, njengezitsha zobumba ezenziwe nge-silicon carbide. Ngakho yiziphi izinzuzo eziyisithupha ze-atmospheric pressure sintering silicon carbide kanye nokusetshenziswa kwe-silicon carbide ceramics?

Izinzuzo eziyisithupha ze-atmospheric pressure sintered silicon carbide materials:

1. Ukuminyana okuphansi

Izinto ze-silicon carbide zinokuminyana okuphansi kunensimbi, okwenza idivayisi ibe lula.

2. Ukumelana nokugqwala

I-Silicon carbide material inezinga eliphezulu lokuncibilika, inertia yamakhemikhali, ukumelana nokushaqeka okushisayo, i-silicon carbide isetshenziswa kuma-abrasives, okhini be-ceramic, izikhala ze-silicon carbide, zingasetshenziswa embonini yokuncibilikisa nokuncibilikisa ngesithando somlilo esiqondile se-cylinder distillation, isitini, i-aluminium electrolytic cell lining. , i-tungsten, isithando somlilo esincane neminye imikhiqizo ye-silicon carbide ceramic.

I-3, izinga lokushisa eliphezulu, i-coefficient yokwandisa okushisayo iyancipha

I-silicon carbide material ikhiqizwa emazingeni okushisa aphezulu. Kwezinye izindawo zokushisa okuphezulu, izinto ezidinga amandla okucubungula nokunemba kokucubungula okungafinyelelwa yi-silicon carbide ceramics ziyadingeka. Izinga lokushisa eliphakeme le-silicon carbide lingaba ngu-800, kanti izinga lokushisa lensimbi lingama-250 kuphela. Ukubala okunzima, isilinganiso sokunwetshwa kokushisa okushisayo kwe-silicon carbide ebangeni lama-25 ~ 1400 ngu-4.10-6 / C. I-coefficient yokwandisa okushisayo ye-silicon carbide iyalinganiswa, futhi imiphumela ibonisa ukuthi inani lincane kakhulu kunezinye izinto zokuhushula kanye nezinga lokushisa eliphezulu. I-silicon carbide e-sintered ngaphansi kwengcindezi yomoya

4, high conductivity ezishisayo

I-thermal conductivity yezinto ze-silicon carbide iphezulu, okungesinye isici esibalulekile sezinto ezibonakalayo ze-silicon carbide. I-thermal conductivity ye-silicon carbide inkulu kakhulu kunezinye i-refractories nama-abrades, cishe izikhathi ezi-4 kune-corundum. I-Silicon carbide ine-coefficient ephansi yokwanda okushisayo kanye ne-thermal conductivity ephezulu, ngakho-ke ucezu lomsebenzi luzobhekana nengcindezi encane yokushisa ngesikhathi sokushisa nokupholisa. Yingakho izingxenye ze-SiC zimelana kakhulu nokushaqeka.

I-5, amandla aphezulu emishini, ukuqina okuhle

Amandla emishini yezinto ze-silicon carbide aphakeme kakhulu, avimbela ukuguquguquka kwezinto. I-silicon carbide inamandla amakhulu emishini kune-corundum.

I-6, ubulukhuni obukhulu nokumelana nokugqoka

Ukuqina kwezinto ze-silicon carbide kuphezulu kakhulu, futhi ubulukhuni begebe le-Moss buyi-9.2 ~ 9.6, okwesibili ngemuva kwedayimane ne-tungsten carbide. Uma kuqhathaniswa nezinto zensimbi yensimbi, inikeza ubulukhuni obuphezulu, i-coefficient ephansi yokungqubuzana, ukungqubuzana okuphansi kakhulu, ukuhwaqeka okuncane kwendawo kanye nokumelana okuhle kokugqoka ngaphandle kokugcoba. Ngaphezu kwalokho, imelana nezinto zangaphandle, ithuthukisa ukubekezelelana kwendawo. I-silicon carbide e-sintered ngaphansi kwengcindezi yomoya

Ukusetshenziswa kwe-atmospheric pressure sintered silicon carbide ceramics

1, ukukhiqizwa kwe-silicon carbide yezinto zobumba ezikhethekile

I-silicon carbide impahla iyimpahla enobulukhuni obuphezulu nezindleko eziphansi, ezingakhiqiza imikhiqizo ye-silicon carbide, njenge-silicon carbide seals, imikhono ye-silicon carbide, amapuleti e-silicon carbide bulletproof, amaphrofayili e-silicon carbide, njll., angasetshenziswa ezimpawini zemishini kanye amaphampu ahlukahlukene. I-silicon carbide e-sintered ngaphansi kwengcindezi yomoya

2, ukukhiqizwa kwezinto ezibonakalayo ze-zirconia zama-ceramics akhethekile

I-Zirconia ceramic ine-conductivity ephezulu ye-ionic, ukuzinza okuhle kwamakhemikhali nokuqina kwesakhiwo, futhi isiphenduke into efundwa kabanzi futhi esetshenziswayo ye-electrolyte. Ngokwenza ngcono inqubo yokukhiqiza ifilimu ye-electrolyte ye-zirconia esekelwe, ukunciphisa izinga lokushisa lokusebenza kanye nezindleko zokukhiqiza lezi zinto, nokulwela ukufeza ukuthuthukiswa kwezimboni nakho kuyisiqondiso esibalulekile socwaningo lwesikhathi esizayo.
