Hauv ntau qhov xwm txheej kev tsim khoom lag luam, nws feem ntau tsim nyog los thauj cov kua uas muaj cov khoom khov, uas peb hu ua slurry. Qhov kev thov no yog qhov tshwm sim ntau heev hauv kev lag luam xws li kev khawb av, metallurgy, fais fab, thiab kev tsim tshuaj lom neeg. Thiab covtwj tso kua dejyog cov khoom siv tseem ceeb uas muaj lub luag haujlwm rau kev xa cov haujlwm. Ntawm ntau yam khoom ntawm lub twj tso kua mis slurry, lub hauv paus ua lub luag haujlwm tseem ceeb vim nws ncaj qha kov cov slurry. Nws tsis tsuas yog tiv taus kev yaig thiab kev hnav ntawm cov khoom khov hauv cov slurry, tab sis kuj tiv taus kev xeb ntawm ntau yam tshuaj lom neeg. Qhov chaw ua haujlwm hnyav heev.
Cov ntaub ntawv ib txwm muaj rau cov twj tso kua dej, xws li hlau thiab roj hmab, feem ntau muaj qee qhov tsis zoo thaum ntsib cov xwm txheej ua haujlwm nyuaj. Txawm hais tias cov hlau sab hauv muaj lub zog siab, nws qhov kev tiv thaiv kev hnav thiab kev tiv thaiv corrosion yog txwv. Kev siv ntev tuaj yeem ua rau hnav thiab xeb yooj yim, ua rau kev saib xyuas cov khoom siv ntau zaus thiab luv lub neej kev pabcuam. Qhov kev tiv thaiv kev hnav thiab kev tiv thaiv corrosion ntawm cov roj hmab sab hauv yog qhov zoo, tab sis lawv cov kev ua tau zoo yuav raug txo qis heev hauv qhov kub thiab txias, siab siab, lossis cov chaw muaj zog acid-base, uas tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev tsim khoom lag luam.
Qhov tshwm sim ntawm cov khoom siv silicon carbide tau coj los ua ib qho kev daws teeb meem zoo tshaj plaws rau qhov teeb meem ntawm cov twj tso kua mis slurry. Silicon carbide yog ib hom khoom siv ceramic tshiab nrog ntau yam khoom zoo heev, xws li nws qhov nyuaj heev, thib ob tsuas yog pob zeb diamond. Qhov no ua rau cov silicon carbide hauv pem teb tiv taus kev yaig ntawm cov khoom khov hauv cov slurry, txhim kho qhov hnav tsis kam ntawm lub twj tso kua mis slurry; Nws kuj muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem tiv taus yuav luag txhua hom inorganic acids, organic acids, thiab alkalis. Nws muaj ntau yam kev siv hauv kev lag luam xws li kev tsim tshuaj lom neeg uas xav tau kev tiv thaiv corrosion siab; Silicon carbide muaj kev ruaj khov tshuaj lom neeg zoo thiab tuaj yeem tswj tau kev ua haujlwm ruaj khov hauv qab qhov kub thiab txias siab. Nws tsis yooj yim raug tshuaj lom neeg, uas ua rau nws ua haujlwm ib txwm nyob rau hauv ntau qhov chaw lag luam.
Los ntawm qhov kev xav ntawm cov txiaj ntsig ntawm kev siv, qhov zoo ntawm cov twj tso kua mis silicon carbide slurry yog qhov pom tseeb heev. Ua ntej, nws lub neej ua haujlwm ntev dua. Piv nrog cov ntaub ntawv ib txwm muaj, qhov kev tiv thaiv hnav ntawm silicon carbide hauv pem teb tuaj yeem ncav cuag ntau zaus ntawm cov hlau chromium hnav-resistant alloys, uas tuaj yeem txo qhov zaus ntawm kev saib xyuas thiab hloov khoom siv, thiab txo cov nqi khiav lag luam ntawm cov tuam txhab. Qhov thib ob, vim yog qhov du ntawm silicon carbide hauv pem teb, nws tuaj yeem txo qhov kev tiv thaiv ntws ntawm slurry thaum lub sijhawm thauj mus los, txhim kho kev ua haujlwm ntawm lub twj tso kua mis, thiab yog li txuag kev siv hluav taws xob. Tsis tas li ntawd, qhov ruaj khov ntawm silicon carbide hauv pem teb yog siab, uas tuaj yeem hloov kho rau ntau qhov chaw ua haujlwm nyuaj thiab muab kev lees paub zoo rau kev txuas ntxiv thiab kev ruaj khov ntawm kev tsim khoom lag luam.
Silicon carbide slurry twj tso kua mis hauv ob sab phlu, ua cov khoom siv ua tau zoo, tau qhia txog cov txiaj ntsig zoo thiab muaj peev xwm hauv kev thauj mus los hauv kev lag luam. Nrog rau kev nce qib ntawm thev naus laus zis thiab kev txo qis maj mam ntawm cov nqi, nws ntseeg tias nws yuav raug siv dav hauv ntau lub lag luam, muab kev txhawb nqa zoo dua rau kev txhim kho kev tsim khoom lag luam.
