Hauv kev lag luam uas muaj qhov kub thiab txias siab, cov xov xwm corrosive, thiab cov xwm txheej ua haujlwm hnyav feem ntau tshwm sim, cov ntaub ntawv ib txwm muaj feem tsis txaus. Ua tus thawj coj hauv kev siv tshuab ceramic sintered silicon carbide, peb paub zoo txog qhov uas cov khoom siv hloov pauv no txhais cov ciam teb ntawm kev siv tshuab pauv cua sov li cas. Tsab xov xwm no yuav coj koj mus nkag siab tias vim li cassilicon carbide cua sov exchangerstau dhau los ua "tus neeg ua haujlwm txhua yam" hauv cov chaw ib puag ncig nyuaj.
Plaub Qhov Zoo ntawm Silicon Carbide
Silicon carbide (SiC) yog cov khoom siv ceramic siab heev uas tau tsim los ntawm kev dag, thiab nws cov khoom sib xyaw ua ke ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv pauv cua sov hauv qab cov xwm txheej ua haujlwm hnyav
1. Kev ua tau zoo heev ntawm thermal conductivity
Qhov ua tau zoo ntawm silicon carbide thermal conductivity ntau dua li cov khoom siv hlau xws li stainless hlau, thiab nws tuaj yeem hloov pauv cua sov sai sai hauv qhov kub siab, txhim kho kev siv hluav taws xob zoo thaum txo cov khoom siv.
2. Tsis ntshai qhov kub thiab txias heev
Cov ntaub ntawv hlau feem ntau yuav mos thiab deformed nyob rau hauv qhov kub siab, thaum silicon carbide tuaj yeem tswj tau qhov ruaj khov ntawm cov qauv hauv qhov chaw siab dua 1350 ° C, ua rau nws yog tus khub txhim khu kev qha mus sij hawm ntev rau cov khoom siv xws li cov qhov cub kub thiab cov tshuaj reactors.
3. Ib tug kws tshaj lij hauv kev tiv thaiv xeb
Txawm nyob rau hauv cov xov xwm corrosive xws li cov kua qaub muaj zog lossis cov ntsev ntau, ib txheej oxide tiv thaiv yuav tsim rau ntawm qhov chaw ntawm silicon carbide kom tiv thaiv kev yaig tshuaj thiab txo qhov zaus txij nkawm.
Lub ntsiab lus ntawm cov txheej txheem sintering reaction
Peb lub tshuab thev naus laus zis tseem ceeb, reaction sintered silicon carbide (RBSC), tsim cov khoom sib xyaw ua los ntawm cov khoom siv ceramic uas tuab thiab sib npaug los ntawm kev nkag mus rau hauv cov khoom siv silicon rau hauv cov pa roj carbon matrix uas muaj qhov porous. Qhov kev tshawb pom tshiab no coj peb qhov zoo tseem ceeb:
-Txo cov ntsiab lus tsis muaj zog uas tshwm sim los ntawm cov qhov hws sab hauv hauv cov ntaub ntawv sintered ib txwm muaj
-Ua kom zoo dua cov qauv tsim ntawm cov kav dej ntws kom zoo dua qub kom ua tau zoo dua qub
- Kev sib npaug ntawm kev ua tau zoo thiab kev tswj tus nqi
Kev ruaj khov mus sij hawm ntev, txo nqi thoob plaws hauv lub neej tag nrho
Qhov kev hloov pauv ntawm cov hlau hloov pauv cua sov ib txwm muaj ntau zaus vim yog xeb thiab kev tawg tau dhau los ua keeb kwm. Qhov ruaj khov ntawm cov ntaub ntawv silicon carbide ua rau muaj kev paub txog kev ua haujlwm tsis muaj kev txhawj xeeb thaum lub sijhawm teeb tsa, tsim kom muaj txiaj ntsig thoob plaws hauv lub neej ntawm cov khoom siv.
Ua ib tug kws tsim kho tshiab tshwj xeeb hauv kev ua haujlwm sintered silicon carbide rau ntau tshaj 20 xyoo,Shandong Zhongpengyeej ib txwm cog lus tias yuav muab cov kev daws teeb meem kev tswj cua sov rau cov neeg siv khoom. Txawm hais tias koj xav tau kho dua cov kab ke uas twb muaj lawm lossis tsim cov khoom siv tshiab, peb pab neeg yuav pab koj siv tag nrho cov peev xwm ntawm cov ntaub ntawv silicon carbide.
