Hauv lub cub tawg kub uas tseem ua haujlwm hauv lub chaw ua haujlwm hlau, ib qho khoom siv ceramic nyob ntsiag to nyiaj dhau qhov kub kub; Hauv lub tshuab desulfurization roj flue, lub nozzle ceramic tiv taus qhov kev sim xeb ntawm cov kua qaub thiab alkali muaj zog. Cov 'neeg ua siab loj tsis paub' hauv cov xwm txheej kev lag luam no yog ob qho khoom siv ceramic siab heev uas peb yuav tshawb nrhiav hnub no -silicon carbidethiab txhuas oxide.
1. Kev sib cav sib ceg ncaj qha: Leej twg yog tus 'Diamond Body' tiag tiag?
Raws li "armor" hauv kev lag luam, qhov nyuaj ntawm cov ntaub ntawv ncaj qha txiav txim siab lawv lub neej kev pabcuam. Qhov nyuaj ntawm silicon carbide ceramics yog ze rau ntawm cov pob zeb diamond ntuj, qhia txog kev ua siab ntev zoo kawg nkaus nyob rau hauv cov xwm txheej sib txhuam tas mus li. Ib yam li txiav iav nrog pob zeb diamond, thaum alumina ceramics qhia cov khawb me me thaum hnav ntev, silicon carbide tseem tswj tau qhov chaw du. Cov yam ntxwv no txuas ntxiv nws lub neej kev pabcuam ntau zaus ntev dua li alumina ceramics hauv cov xwm txheej xws li twj tso kua mis rau kev xa cov slurry thiab nozzles rau kev ua haujlwm raug.
2, Tus 'King Endurance' ntawm High Temperature Battlefield
Thaum nkag mus rau hauv lub chaw ua khoom siv, lub cua sov loj heev ua rau peb nco qab tias cov khoom siv tiv taus kub siab tiag tiag yog qhov xav tau ntawm no. Peb cov khoom siv silicon carbide ceramics tuaj yeem tswj tau qhov ruaj khov ntawm cov qauv txawm tias ntawm 1350 ℃, qhia txog lawv lub peev xwm los tiv taus kub heev. Cov khoom siv silicon carbide ceramics yooj yim rau kev tsim thiab muaj lub neej ntev, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau cov teb tshiab xws li kev tiv taus kub hauv qhov cub, kev kho cua sov hlau, thiab kev txhawb nqa semiconductor ib leeg siv lead ua rau lub cub tawg.
3, Tus 'Tus Saib Xyuas Zoo Tshaj Plaws' nyob rau hauv Tshuaj Lom Zem Corrosion
Ntsib nrog "nag kua qaub" hauv cov chaw tsim tshuaj lom neeg, cov khoom siv silicon carbide uas muaj cov khoom siv siab ua rau muaj kev ruaj khov zoo kawg nkaus, ib yam li muab cov khaub ncaws tiv thaiv tsis pom rau ntawm cov khoom siv, txawm tias raug rau cov xov xwm hnyav xws li cov kua qaub sulfuric thiab cov txhuas molten ntev, lawv tseem nyob ruaj khov. Txawm li cas los xij, alumina ceramics yuav muaj "kev tawg" hauv cov chaw tshwj xeeb xws li hydrofluoric acid, uas ua rau cov khoom siv silicon carbide uas muaj cov khoom siv siab ua rau muaj kev hloov pauv tsis tau hauv cov ntaub thaiv kev xeb, cov roj teeb lithium sintering, thiab lwm yam xwm txheej.
4. Kev Hloov Pauv Tus Nqi Uas Tsis Pom Kev
Txawm hais tias kev nqis peev thawj zaug hauv silicon carbide ceramics yog siab dua me ntsis, cov txiaj ntsig mus sij hawm ntev uas nws coj los ntau dua li kev xav. Peb cov neeg siv khoom tau txo lawv qhov kev saib xyuas txhua xyoo tom qab hloov lub phaj silicon carbide hnav-resistant. Qhov "kev nqis peev ib zaug xwb, cov txiaj ntsig mus sij hawm ntev" no yog kev hloov kho tus nqi ntawm kev lag luam tsim khoom.
Sawv ntawm txoj kev sib tshuam ntawm kev txhim kho kev lag luam, kev xaiv cov khoom siv tau dhau los ua qhov chaw tseem ceeb rau kev sib tw ntawm cov tuam txhab. Silicon carbide ceramics, nrog lawv cov kev ua tau zoo tag nrho, tsis yog tsuas yog txhais cov ciam teb ntawm kev siv cov khoom siv ceramics hauv kev lag luam xwb, tab sis kuj txhawb kev hloov pauv ntawm kev tsim khoom mus rau kev ua haujlwm zoo dua thiab kev txuag hluav taws xob. Thaum cov khoom siv tsim khoom xav tau ntsib cov teeb meem nyuaj dua, qhov "ntau yam" no los ntawm kev tshawb fawb niaj hnub no muab cov kev daws teeb meem rau cov tuam txhab lag luam yav tom ntej.
