Hauv cov chaw tsim khoom lag luam, cov kav dej yog "lifeline" rau kev thauj khoom. Txawm li cas los xij, ntsib kev yaig thiab hnav ntawm cov xov xwm tawv xws li xuab zeb, slurry, thiab cov khib nyiab pov tseg, cov kav dej zoo tib yam feem ntau cuam tshuam thiab kev puas tsuaj hauv lub sijhawm luv luv. Qhov no tsis tsuas yog yuav tsum tau kaw ntau zaus thiab hloov pauv, tab sis kuj tseem tuaj yeem ua rau muaj kev nyab xeeb. Ntawm ntau cov kav dej hnav-tiv taus, cov kav dej silicon carbide hnav-tiv taus tau dhau los ua cov khoom kub hauv kev lag luam vim lawv cov kev hnav zoo dua. Niaj hnub no, peb yuav tham txog qhov "hardcore player" hauv kev lag luam pipeline.
Ntau tus neeg yuav tsis paub txog cov khoom siv silicon carbide. Cias muab tso, nws yog ib qho khoom siv tsis muaj hlau tsis muaj hlau nrog lub hardness thib ob rau pob zeb diamond, thiab ib txwm muaj "tiv thaiv kev tsim khoom" cov khoom. Cov yeeb nkab hnav-tiv taus ua los ntawm nws yog zoo li muab ib txheej ntawm "pob zeb diamond armor" rau hauv cov kav dej, uas tuaj yeem tiv taus qhov cuam tshuam ntawm ntau yam kev hnav siab tshaj tawm.
Piv nrog cov kav hlau ib txwm siv thiab cov kav dej ceramic, qhov zoo ntawmsilicon carbide coj-resistant kavyog qhov tseem ceeb heev. Ua ntej, nws muaj kev hnav tsis kam. Txawm hais tias kev thauj cov slurry uas muaj quartz xuab zeb lossis cov khib nyiab pov tseg nrog cov khoom nyuaj, nws tuaj yeem tswj tau nws qhov kev ncaj ncees ntawm qhov chaw thiab muaj kev pabcuam lub neej ob peb zaug ntev dua li cov kav hlau zoo tib yam, txo qhov zaus thiab tus nqi ntawm cov kav dej hloov. Secondly, nws muaj zog corrosion kuj. Cov khoom siv feem ntau muaj corrosive Cheebtsam xws li cov kua qaub thiab alkali, thiab cov kav dej zoo tib yam yog qhov ua rau corrosion thiab laus. Txawm li cas los xij, silicon carbide nws tus kheej muaj cov tshuaj lom neeg ruaj khov thiab tuaj yeem tiv thaiv kev yaig ntawm ntau yam kua qaub thiab alkali media, ua rau nws tsim nyog rau ntau qhov chaw ua haujlwm.
Tsis tas li ntawd, cov kav dej silicon carbide hnav-tiv taus kuj tseem muaj kev xav zoo - thermal conductivity zoo, uas tuaj yeem ua kom sov sai sai thaum thauj cov ntaub ntawv kub, tsis txhob muaj cov kav dej deformation los ntawm qhov kub thiab txias hauv zos, thiab txo cov cua sov, indirectly txo cov khoom siv hluav taws xob. Ntxiv mus, nws cov qauv compact ua rau nws tsis txawv ntau ntawm cov kav dej zoo tib yam thaum ntsia, tsis tas yuav tsum tau hloov cov khoom siv ntxiv. Nws muaj teeb meem tsawg hauv kev pib thiab tuaj yeem hloov kho tau yooj yim rau ob qho tib si kev tsim kho tshiab thiab kev kho cov kav dej qub.
Niaj hnub no, silicon carbide hnav-resistant kav tau dav siv nyob rau hauv ntau yam lag luam xws li mining, metallurgy, fais fab, thiab tshuaj engineering, xws li slurry thauj hauv mines, desulfurization thiab denitrification systems nyob rau hauv fais fab nroj tsuag, thiab pov tseg residue thauj nyob rau hauv lub metallurgical kev lag luam, qhov twg lawv tuaj yeem pom. Nws tsis tsuas yog daws qhov mob cov ntsiab lus ntawm cov kav dej ib txwm siv uas nyiam hnav thiab xeb, tab sis kuj tseem pab cov lag luam txo qis qis, txo tus nqi tu, thiab txhim kho kev tsim khoom, ua ib qho tseem ceeb "cov cuab yeej hnav-tiv taus" hauv kev lag luam.
Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam thev naus laus zis, kev siv cov khoom siv silicon carbide tseem nthuav dav. Peb ntseeg hais tias yav tom ntej, silicon carbide coj-resistant kav yuav emit lub teeb thiab tshav kub nyob rau hauv ntau segmented teb, muab kev tiv thaiv rau kev ruaj ntseg ntawm kev lag luam ntau lawm.
