Iingenelo ezintandathu ze-carbon dioxide efakwe kwi-atmospheric pressure kunye nokusetyenziswa kwe-silicon carbide ceramics

I-silicon carbide efakwe uxinzelelo lomoya ayisasetyenziswa nje njengento yokurhawuzelela, kodwa njengezinto ezintsha, kwaye isetyenziswa kakhulu kwiimveliso zobuchwepheshe obuphezulu, ezifana neeseramikhi ezenziwe ngezinto ze-silicon carbide. Ngoko ke zeziphi iingenelo ezintandathu ze-silicon carbide efakwe uxinzelelo lomoya kunye nokusetyenziswa kweeseramikhi ze-silicon carbide?

Iingenelo ezintandathu zezinto ze-silicon carbide ezifakwe uxinzelelo lomoya:

1. Uxinano oluphantsi

Izinto ze-silicon carbide zinobunzima obuphantsi kunentsimbi, nto leyo eyenza isixhobo sibe lula.

2. Ukumelana nokugqwala

Izinto ze-silicon carbide zinendawo yokunyibilika ephezulu, i-inertia yeekhemikhali, ukumelana nobushushu, i-silicon carbide isetyenziswa kwi-abrasives, kwii-oven ze-ceramic, kwiiblanks ze-silicon carbide, zingasetyenziswa kushishino lwe-smelting kunye ne-smelting kunye ne-vertical cylinder distillation furnace, izitena, i-aluminium electrolytic cell lining, i-tungsten, i-small furnace kunye nezinye iimveliso ze-silicon carbide ceramic.

3, ubushushu obuphezulu, i-coefficient yokwandiswa kobushushu iyancitshiswa

Izinto ze-silicon carbide zenziwa kumaqondo obushushu aphezulu. Kwezinye iindawo ezinobushushu obuphezulu, kufuneka izinto ezifuna amandla okucubungula kunye nokuchaneka kokucubungula ezinokufikelelwa zii-ceramics ze-silicon carbide. Ubushushu obuphezulu be-silicon carbide bumalunga nama-800, kwaye ubushushu bentsimbi bungama-250 kuphela. Ukubala okurhabaxa, i-coefficient yokwandisa ubushushu ye-silicon carbide ephakathi kwama-25 ~ 1400 yi-4.10-6 /C. I-coefficient yokwandisa ubushushu ye-silicon carbide iyalinganiswa, kwaye iziphumo zibonisa ukuba ubungakanani buncinci kakhulu kunezinye izinto ezirhabaxa kunye nezinto ezinobushushu obuphezulu. I-silicon carbide e-Sintered phantsi koxinzelelo lomoya.

4, ukuhanjiswa kobushushu obuphezulu

Ukuqhuba kobushushu kwezinto ze-silicon carbide kuphezulu, nto leyo enye into ebalulekileyo kwiimpawu zomzimba ze-silicon carbide. Ukuqhuba kobushushu kwe-silicon carbide kukhulu kakhulu kunokwezinye izinto ezirhabaxa kunye nee-abrades, malunga nezihlandlo ezi-4 kune-corundum. I-Silicon carbide inomlinganiselo ophantsi wokwandiswa kobushushu kunye nokuqhuba kobushushu okuphezulu, ngoko ke umsebenzi uya kuba phantsi koxinzelelo oluncinci lobushushu ngexesha lokufudumeza nokuphola. Yingakho izinto ze-SiC zixhathisa ngokukodwa ukutshayiswa.

5, amandla aphezulu oomatshini, ukuqina okuhle

Amandla oomatshini wezinto ze-silicon carbide aphezulu kakhulu, nto leyo ethintela ukuguquka kwezinto. I-Silicon carbide inamandla oomatshini aphezulu kune-corundum.

6, ubulukhuni obuphezulu kunye nokumelana nokuguguleka

Ubunzima bezinto ze-silicon carbide buphezulu kakhulu, kwaye ubunzima be-Moss gap yi-9.2 ~ 9.6, ilandela i-diamond kunye ne-tungsten carbide kuphela. Xa kuthelekiswa nezinto zentsimbi yesinyithi, inika ubunzima obuphezulu, i-coefficient ephantsi yokungqubana, ukungqubana okuphantsi, uburhabaxa obuncinci bomphezulu kunye nokumelana okuhle kokuguguleka ngaphandle kokuthambisa. Ukongeza, ayixhathisi kwizinto zangaphandle, nto leyo ephucula ukunyamezela komphezulu. I-silicon carbide e-Sintered phantsi koxinzelelo lomoya

Ukusetyenziswa kweeseramikhi ze-silicon carbide ezixineneyo zoxinzelelo lomoya

1, ukuveliswa kwezinto ze-silicon carbide zeeseramikhi ezikhethekileyo

Izinto ze-silicon carbide zizinto ezinobunzima obuphezulu kunye nexabiso eliphantsi, ezinokuvelisa iimveliso ze-silicon carbide, ezifana nezitywino ze-silicon carbide, imikhono ye-silicon carbide, iipleyiti ze-silicon carbide ezikhusela iimbumbulu, iiprofayili ze-silicon carbide, njl.njl., ezinokusetyenziswa kwizitywino zoomatshini kunye neepompo ezahlukeneyo. I-silicon carbide egcadiweyo phantsi koxinzelelo lomoya.

2, imveliso yezinto ze-zirconia zeeseramikhi ezikhethekileyo

I-Zirconia ceramic ine-ionic conductivity ephezulu, uzinzo oluhle lweekhemikhali kunye nozinzo lwesakhiwo, kwaye iye yaba yinto efundwa kakhulu kwaye isetyenziswa kakhulu ye-electrolyte. Ngokuphucula inkqubo yokuvelisa ifilimu ye-electrolyte esekelwe kwi-zirconia, ukunciphisa ubushushu bokusebenza kunye neendleko zokuvelisa ezi zinto, kunye nokuzama ukufikelela kwimizi-mveliso kukwayindlela ebalulekileyo yophando lwexesha elizayo.
