Hauv kev tsim khoom lag luam, cov kav dej zoo li "cov hlab ntsha" ntawm cov chaw tsim khoom, uas yog lub luag haujlwm thauj ntau yam kua, roj, thiab txawm tias cov khoom khov. Txawm li cas los xij, qee qhov ntawm cov xov xwm no muaj kev xeb thiab kev tiv thaiv kev hnav, uas tuaj yeem ua rau cov kav dej muaj qhov txhab dhau sijhawm. Qhov no tsis yog tsuas yog cuam tshuam rau kev ua haujlwm ntawm kev tsim khoom xwb tab sis kuj tseem yuav ua rau muaj kev phom sij rau kev nyab xeeb.
Lub sijhawm no, ib txoj kev siv tshuab tiv thaiv kav dej tshwj xeeb -silicon carbide yeeb nkab txheej, maj mam dhau los ua qhov kev daws teeb meem zoo tshaj plaws rau ntau lub tuam txhab.
Silicon carbide yog dab tsi?
Silicon carbide (SiC) yog ib qho sib xyaw ua ke ntawm silicon thiab carbon, uas ua ke qhov kub siab thiab kev tiv taus corrosion ntawm ceramics nrog lub zog siab thiab kev tiv taus kev cuam tshuam ntawm cov hlau. Nws qhov nyuaj yog qhov thib ob tsuas yog pob zeb diamond, ua rau nws nyiam heev hauv kev lag luam ntawm cov ntaub ntawv hnav-resistant.
Vim li cas ho siv silicon carbide rau cov kav dej?
Hais yooj yim xwb, daim ntaub silicon carbide yog ib txheej "tiv thaiv" uas hnav rau ntawm phab ntsa sab hauv ntawm cov kav dej. Nws cov txiaj ntsig tseem ceeb yog:
1. Super hnav-resistant
Qhov siab hardness ntawm silicon carbide tso cai rau nws kom yooj yim tiv taus kev yaig ntawm cov khoom siv hnav siab xws li mortar thiab slurry.
2. Kev tiv thaiv xeb
Txawm nyob rau hauv cov kua qaub, alkali lossis ntsev, silicon carbide tuaj yeem ruaj khov thiab yuav tsis yooj yim eroded.
3. Kev kub siab tsis kam
Txawm tias nyob rau hauv qhov kub siab ntawm ntau pua degrees Celsius, lub silicon carbide hauv pem teb tuaj yeem tswj tau qhov ruaj khov ntawm cov qauv yam tsis muaj kev hloov pauv lossis kev sib cais.
4. Ntev lub neej ntawm cov kav dej
Los ntawm kev txo qhov hnav thiab xeb, silicon carbide lining tuaj yeem ua rau lub neej ua haujlwm ntawm cov kav dej ntev dua, txo qhov zaus hloov pauv thiab cov nqi txij nkawm.
Cov xwm txheej ntawm daim ntawv thov
Cov kav dej silicon carbide siv dav hauv kev lag luam xws li tshuaj lom neeg, kev khawb av, hluav taws xob, thiab kev tiv thaiv ib puag ncig, thiab tshwj xeeb tshaj yog rau kev thauj cov xov xwm uas ua rau muaj kev poob loj hauv cov kav dej, xws li:
-Slurry uas muaj cov khoom khov kho
-Muaj zog corrosive kua
- Cov pa roj kub lossis kua kub
kev xaus lus
Cov kav dej silicon carbide zoo li ntxiv ib lub "tiv thaiv" ruaj khov rau hauv cov kav dej, uas tuaj yeem tiv taus kev hnav thiab xeb, nrog rau kev tiv taus qhov kub thiab txias, thiab yog qhov lav zoo rau kev ua haujlwm ruaj khov mus sij hawm ntev ntawm cov kav dej kev lag luam. Rau cov tuam txhab uas nrhiav kev ua haujlwm zoo, ruaj ntseg, thiab pheej yig, qhov no yog ib txoj kev npaj txhim kho uas tsim nyog xav txog.
