Nyob rau hauv qhov av ntawm lub qhov tsua loj, lub tshuab xa khoom tshiab khiav ruaj khov ntawm qhov ceev ntawm 3 meters ib feeb. Tsis zoo li cov khoom siv ib txwm muaj, nws cov khoom tseem ceeb yog npog nrog ib txheej ntawm cov av dub nrog lub teeb ci ntsa iab - qhov no yog qhov tseebsilicon carbide ceramicshu ua "kub dub hauv kev lag luam". Cov khoom siv zoo li qub no maj mam hloov pauv txoj kev ua haujlwm ntawm cov khoom siv thiab kev saib xyuas ntawm kev lag luam thee.
1, Lub 'Diamond Armor' rau Kev Ntxuav Cyclones
Hauv kev ua haujlwm ntawm cov thee mining, cov khoom siv hnav thiab tsim kua muag tau ntev los ua teeb meem nyuaj rau cov tuam txhab. Cov khoom siv ntxuav cyclone ib txwm muaj feem ntau hnav thiab tsim kua muag vim yog cov xwm txheej ua haujlwm tshwj xeeb, uas xav tau kev qhia txog pebsilicon carbide ceramic pem teb- cov cua daj cua dub nrog silicon carbide ceramic lining tuaj yeem ntev lawv lub neej kev pabcuam ntau zaus ntev dua li cov cua daj cua dub ib txwm muaj. Cov qauv siv lead ua los ntawm honeycomb ua rau nws qhov nyuaj thib ob tsuas yog pob zeb diamond, ua rau nws yog ib qho kev thaiv ntuj tiv thaiv ntau yam kev hnav thiab tsim kua muag.
2, Tus 'neeg saib xyuas kev ruaj ntseg' ntawm lub kaw lus xa khoom
Lub phaj silicon carbide ceramic hauv sab hauv phab ntsa ntawm cov kav dej thauj thee tuaj yeem ua rau lub neej ntawm cov kav dej ntev dua thiab txo tus nqi ntawm kev hloov pauv thiab kaw ntau zaus. Cov khoom siv no tsis tsuas yog muaj kev tiv thaiv kev hnav zoo heev, tab sis nws cov yam ntxwv ntawm qhov chaw du kuj tseem tuaj yeem txo qhov kev thaiv thaum thauj thee. Qhov zoo dua yog tias thaum thauj thee nrog cov ntsiab lus sulfur siab, qhov kev tiv thaiv corrosion zoo heev ntawm silicon carbide ceramics tuaj yeem zam cov teeb meem corrosion ntawm cov kav dej hlau ib txwm muaj.
3, Lub Luag Haujlwm Nyob Hauv Qhov Kub Siab
Hauv kev lag luam tshuaj lom neeg thee, cov khoom siv silicon carbide ceramics ua lub luag haujlwm tseem ceeb. Thaum qhov kub hauv lub cub tawg thee feem ntau ncav cuag 1350 ℃, cov khoom siv refractory ib txwm nyuaj rau tiv taus ntev. Thaum lub tshuab gasifier nozzle ua los ntawm silicon carbide ceramics siv, tsis yog nws lub neej ua haujlwm nce ntau zaus ntawm cov khoom siv ib txwm muaj, tab sis nws cov thermal conductivity tshwj xeeb kuj tseem tuaj yeem ua kom muaj qhov kub thiab txias sib xws, txhim kho kev ua haujlwm ntawm gasification.
4. Lub zog tsav tsheb uas tsis pom kev ntawm kev hloov pauv ntsuab
Nrog rau qhov kev thov kom muaj kev tiv thaiv ib puag ncig ntau ntxiv, kev siv cov khoom siv silicon carbide ceramics hauv cov khoom siv tshem plua plav tau dhau los ua qhov dav dua. Tom qab txau cov txheej txheem silicon carbide ceramic, kev ua haujlwm tshem plua plav tuaj yeem txhim kho tau zoo heev, thaum txo cov pa phem thib ob los ntawm kev xeb ntawm electrode. Kev ua haujlwm ruaj khov ntawm cov khoom siv no hauv cov chaw muaj pa roj kub siab pab cov tuam txhab thee ua tiav kev tsim khoom huv.
Ua ib lub tuam txhab muab kev pabcuam thev naus laus zis uas koom nrog tob hauv kev lag luam ceramics tshwj xeeb, peb txuas ntxiv txhawb kev siv cov khoom siv silicon carbide ceramics tshiab hauv kev lag luam thee. Txij li kev khawb av hauv av mus rau kev tsim tshuaj thee, los ntawm kev tiv thaiv cov khoom siv mus rau kev txhim kho ib puag ncig, "cov khoom siv khawv koob" no los ntawm chav kuaj mob tab tom sau ib tshooj tshiab hauv kev txhim kho qhov zoo thiab kev ua haujlwm ntawm kev lag luam zog ib txwm muaj. Yav tom ntej, peb yuav txuas ntxiv tshawb nrhiav cov peev xwm tsis kawg ntawm cov khoom siv thev naus laus zis thiab muab kev txhawb nqa zoo dua rau kev txhim kho zoo ntawm kev lag luam thee.
