Hauv kev tsim khoom lag luam niaj hnub no, cov khoom siv feem ntau ntsib qhov chaw ua haujlwm hnyav, thiab kev hnav thiab tsim kua muag tau dhau los ua qhov tseem ceeb uas cuam tshuam rau kev ua haujlwm zoo thiab cov nqi.Silicon carbide ceramic hnav-resistant lining, ua ib yam khoom siv ua tau zoo, maj mam tshwm sim thiab muab cov kev daws teeb meem zoo heev rau ntau qhov chaw lag luam. Niaj hnub no, cia peb kawm txog cov txheej txheem tiv thaiv kev hnav ntawm silicon carbide ceramics.
1, Lub 'muaj zog loj' ntawm silicon carbide ceramics
Silicon carbide (SiC) ceramics yog cov khoom sib xyaw ua ke uas muaj ob lub ntsiab lus, silicon thiab carbon. Txawm hais tias nws yooj yim sib xyaw, nws muaj kev ua tau zoo heev.
1. Kev tawg ntawm qhov nyuaj: Qhov nyuaj ntawm silicon carbide ceramics tsuas yog qis dua me ntsis ntawm cov pob zeb diamond nyuaj tshaj plaws hauv xwm. Qhov no txhais tau tias nws tuaj yeem yooj yim tiv taus kev khawb thiab txiav ntawm ntau yam khoom tawv, thiab tseem tswj tau qhov ruaj khov hauv qhov chaw hnav siab, ib yam li muab ib txheej ntawm cov cuab yeej tawv rau ntawm cov khoom siv.
2. Kev hnav tsis kam thiab kev tsim khoom tsis kam: Nrog nws qhov nyuaj heev thiab cov qauv siv lead ua tshwj xeeb, silicon carbide ceramics muaj kev tiv thaiv kev hnav zoo heev. Nyob rau hauv tib qho kev hnav, nws tus nqi hnav qis dua li cov khoom siv hlau ib txwm muaj, ua rau lub neej ua haujlwm ntawm cov khoom siv ntev dua thiab txo lub sijhawm thiab tus nqi poob los ntawm kev hloov khoom ntau zaus.
3. Kev tiv taus kub siab: Silicon carbide ceramics kuj muaj kev tiv taus kub zoo heev thiab tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev ntawm qhov kub ntawm 1400 ℃ lossis siab dua. Qhov no ua rau nws ua lub luag haujlwm tseem ceeb hauv cov teb kev lag luam kub siab xws li hlau smelting, thermal fais fab, thiab lwm yam. Nws yuav tsis deform, mos lossis poob nws cov kev ua tau zoo thawj vim kub siab.
4. Kev ruaj khov tshuaj lom neeg muaj zog: Tsuas yog ob peb yam khoom xws li hydrofluoric acid thiab concentrated phosphoric acid, silicon carbide ceramics muaj zog heev rau feem ntau cov kua qaub muaj zog, cov hauv paus muaj zog, thiab ntau yam hlau molten, thiab lawv cov khoom siv tshuaj lom neeg ruaj khov heev. Hauv kev lag luam xws li tshuaj lom neeg thiab roj av, ntsib ntau yam xov xwm corrosive, nws tuaj yeem tiv thaiv cov khoom siv los ntawm kev xeb thiab xyuas kom meej tias muaj kev tsim khoom du.
2, Cov xwm txheej siv ntawm silicon carbide ceramic hnav-resistant lining
Raws li kev ua tau zoo heev uas tau hais los saum toj no, silicon carbide ceramic hnav-resistant lining tau siv dav hauv ntau qhov chaw lag luam.
1. Kev khawb av: Thaum lub sijhawm thauj cov hlau, cov khoom xws li cov kav dej khoov thiab cov chutes muaj kev cuam tshuam loj heev rau kev cuam tshuam ceev thiab kev sib txhuam los ntawm cov hlau me me, ua rau muaj kev hnav thiab tsim kua muag hnyav. Tom qab kev teeb tsa silicon carbide ceramic hnav-resistant lining, qhov kev tiv thaiv kev hnav ntawm cov khoom no tau zoo dua, thiab lub neej kev pabcuam tuaj yeem ntev dua los ntawm ob peb lub hlis mus rau ntau xyoo, txo cov sijhawm kho khoom siv thiab txhim kho kev ua haujlwm ntau lawm.
2. Kev lag luam fais fab: Txawm hais tias nws yog lub thawv tso hmoov thiab lub tshuab tshem tawm cov tshauv pneumatic ntawm cov chaw tsim hluav taws xob thermal, lossis cov hniav xaiv hmoov thiab cov ntaub thaiv cua daj cua dub ntawm cov chaw tsim cement, lawv txhua tus ntsib ntau qhov kev yaig thiab kev hnav ntawm cov hmoov av. Silicon carbide ceramic hnav-resistant lining, nrog nws qhov kev tiv thaiv zoo heev, txo cov khoom siv hnav, ntev lub neej kev pabcuam ntawm cov khoom siv, thiab tseem txo cov sijhawm tsis ua haujlwm los ntawm cov khoom siv tsis ua haujlwm, ua kom muaj kev ua haujlwm ruaj khov ntawm lub zog thiab kev tsim cement.
3. Kev lag luam tshuaj lom neeg: Kev tsim tshuaj lom neeg feem ntau muaj ntau yam tshuaj lom neeg xws li cov kua qaub thiab alkalis muaj zog, thiab cov khoom siv kuj tseem yuav muaj ntau qib kev hnav thiab tsim kua muag thaum lub sijhawm ua haujlwm. Silicon carbide ceramic hnav-resistant lining yog ob qho tib si corrosion-resistant thiab hnav-resistant, thiab tuaj yeem hloov kho kom zoo rau qhov chaw ua haujlwm nyuaj no, ua kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm cov khoom siv tshuaj lom neeg. Hauv cov xwm txheej xws li lithium roj teeb tsim khoom uas xav tau cov khoom siv huv si heev, nws kuj tseem tuaj yeem zam kev ua qias tuaj ntawm cov hlau thiab ua kom cov khoom zoo.
Cov ntaub thaiv kev hnav-resistant silicon carbide ceramic muab kev tiv thaiv kev hnav-resistant rau cov khoom siv hauv kev lag luam nrog nws cov kev ua tau zoo heev, ua tus pabcuam muaj zog rau ntau lub lag luam los txhim kho kev tsim khoom thiab txo cov nqi. Yog tias koj lub tuam txhab kuj ntsib kev hnav thiab rhuav tshem cov khoom siv, koj tuaj yeem xav txog kev xaiv peb cov ntaub thaiv kev hnav-resistant silicon carbide ceramic los pib tshooj tshiab hauv kev tsim khoom zoo!
