Hauv ntau yam ntawm kev tsim khoom lag luam, kev hnav thiab tsim kua muag ntawm cov khoom siv yeej ib txwm yog qhov tseem ceeb uas cuam tshuam rau kev ua haujlwm zoo thiab tus nqi. Txhawm rau daws qhov teeb meem no, ntau yam khoom siv tiv taus kev hnav tau tshwm sim, ntawm cov uas silicon carbide hnav-resistant lining tau maj mam dhau los ua "nyiam tshiab" hauv kev lag luam vim nws qhov kev ua tau zoo heev. Niaj hnub no, cia peb nkag mus rau hauv cov khoom siv khawv koob no.
1. Dab tsi yogsilicon carbide hnav-resistant lining?
Silicon carbide (SiC) yog ib qho sib xyaw ua ke ntawm silicon thiab carbon, nrog rau cov qauv siv lead ua tshwj xeeb thiab ruaj khov. Nws cov qauv tseem ceeb yog interwoven SiC thiab CSi tetrahedra. Silicon carbide hnav-resistant lining yog ib txheej tiv thaiv ua los ntawm silicon carbide khoom siv los tiv thaiv sab hauv ntawm cov khoom siv los ntawm kev hnav thiab tsim kua muag. Nws tuaj yeem ua rau ntau yam duab, xws li ceramic rings, ceramic liners, thiab lwm yam, thiab tom qab ntawd ntsia rau ntawm phab ntsa sab hauv ntawm cov khoom siv xws li cov kav dej, lub cev twj tso kua mis, thiab silos uas yooj yim rau cov khoom siv yaig thiab kev sib txhuam.
2, Cov txiaj ntsig ntawm silicon carbide hnav-resistant lining
1. Kev tawv siab thiab kev tiv taus hnav zoo heev: Qhov tawv ntawm silicon carbide ceramics yog qhov siab heev, thib ob tsuas yog pob zeb diamond nyuaj tshaj plaws hauv xwm. Qhov kev tawv siab no ua rau nws muaj zog heev tiv taus kev hnav, muaj peev xwm tiv taus kev yaig ceev ceev thiab kev sib txhuam muaj zog ntawm cov ntaub ntawv, ua rau lub neej ua haujlwm ntawm cov khoom siv ntev dua, ua rau nws yog cov khoom siv tiv taus hnav zoo tshaj plaws hauv kev hnav hnyav. Piv nrog rau lwm cov ntaub ntawv tiv taus hnav ib txwm muaj, silicon carbide hnav-resistant lining muaj qhov zoo tseem ceeb hauv kev tiv taus hnav, uas tuaj yeem txo qhov zaus ntawm kev saib xyuas thiab hloov khoom siv rau cov lag luam thiab txo cov nqi tsim khoom.
2. Qhov ceev tsawg thiab lub teeb yuag: Silicon carbide muaj qhov ceev qis dua li cov hlau xws li hlau. Piv txwv li, qhov ceev ntawm cov khoom siv sintered silicon carbide tsuas yog 3.0g / cm ³, thaum qhov ceev ntawm cov khoom siv sintered silicon carbide tsis muaj siab yog 3.14-3.0g / cm ³. Hauv cov ntaub ntawv ntawm tib lub ntim, qhov hnyav ntawm silicon carbide hnav-resistant lining yog sib dua, uas tsis tsuas yog pab txhawb kev thauj mus los thiab kev teeb tsa, tab sis kuj txo cov khoom siv thauj khoom, ua rau cov khoom siv ua haujlwm yooj yim dua, thiab ua rau kev teeb tsa cov kav dej thiab lwm yam khoom siv siab dua thiab deb dua.
3. Kev tiv taus kub siab: Nws muaj kev ruaj khov zoo thermal thiab cov qauv siv lead ua tshwj xeeb ntawm silicon carbide tso cai rau nws kom tiv taus qhov kub siab, nrog rau qhov kub sintering txog li 1350 ℃. Cov yam ntxwv no ua rau cov silicon carbide hnav-resistant lining kom tswj tau kev ua haujlwm ruaj khov txawm tias nyob rau hauv qhov chaw kub siab, tsis muaj deformation lossis puas tsuaj vim qhov kub siab, ua rau nws haum rau ntau yam kev lag luam kub siab xws li metallurgy, fais fab thiab lwm yam lag luam.
4. Kev tiv thaiv xeb: Silicon carbide muaj cov khoom siv tshuaj ruaj khov thiab tuaj yeem ua kom pom kev tiv thaiv xeb zoo thaum ntsib ntau yam tshuaj lom neeg. Txawm hais tias nyob rau hauv kev thauj mus los ntawm cov kua qaub thiab alkaline muaj zog hauv kev tsim tshuaj lom neeg lossis hauv kev tiv thaiv ib puag ncig xws li kev kho dej phwj tuaj, silicon carbide hnav-resistant lining tuaj yeem tiv thaiv cov khoom siv tau zoo, tiv thaiv cov khoom siv los ntawm kev xeb los ntawm cov tshuaj lom neeg, thiab txuas ntxiv lub neej kev pabcuam ntawm cov khoom siv.
5. Kev ua hluav taws xob tsis zoo thiab tiv thaiv hluav taws xob: Silicon carbide ceramics muaj kev ua hluav taws xob tsis zoo, uas ua rau lawv haum rau cov ntawv thov uas muaj kev cai nruj rau hluav taws xob zoo li qub, xws li cov chaw ua haujlwm tiv thaiv kev tawg. Hauv cov chaw no, hluav taws xob zoo li qub yuav ua rau muaj kev phom sij loj heev, thiab lub luag haujlwm tiv thaiv hluav taws xob ntawm silicon carbide hnav-resistant lining tuaj yeem tiv thaiv kev sib sau ua ke ntawm hluav taws xob zoo li qub thiab ua kom muaj kev nyab xeeb ntau lawm.
6. Yooj yim rau kev tsim, muaj peev xwm ua cov khoom loj thiab cov duab nyuaj: Silicon carbide tuaj yeem ua tiav siv cov txheej txheem xws li kev sib xyaw ua ke, uas muab nws cov txiaj ntsig zoo hauv kev tsim. Los ntawm cov txheej txheem no, cov khoom siv ceramic loj thiab cov khoom siv ceramic uas muaj cov qauv nyuaj tuaj yeem tsim tau. Qhov no txhais tau tias txawm tias cov duab thiab qhov loj ntawm cov khoom siv tshwj xeeb npaum li cas los xij, cov ntaub ntawv tiv taus silicon carbide tuaj yeem hloov kho kom tau raws li qhov xav tau ntawm cov khoom siv lag luam sib txawv.
Cov ntaub thaiv kev hnav silicon carbide tau ua pov thawj tias muaj txiaj ntsig zoo rau kev siv hauv kev lag luam vim nws muaj ntau yam zoo. Nrog rau kev txhim kho thiab kev nce qib ntawm cov ntaub ntawv tshawb fawb, nws ntseeg tau tias cov ntaub thaiv kev hnav silicon carbide yuav raug siv rau ntau qhov chaw, muab kev txhawb nqa zoo dua rau kev ua haujlwm zoo thiab ruaj khov ntawm kev tsim khoom lag luam.
