Kev xa khoom lag luam 'lub zog tiv taus hnav': lub zog tseem ceeb ntawm silicon carbide slurry twj tso kua mis

Hauv cov txheej txheem thauj khoom ntawm cov lag luam xws li kev khawb av, metallurgy, thiab kev tsim kho tshuaj lom neeg, cov twj tso kua mis slurry yog "cov khoom txav" tiag tiag uas muaj lub luag haujlwm thauj cov khoom xws li slurry thiab av nkos uas muaj cov khoom khov. Txawm li cas los xij, cov twj tso kua mis slurry feem ntau muaj lub neej luv luv thiab tsis yooj yim rau kev hnav thiab xeb, thaum muaj kev tshwm sim ntawmsilicon carbide slurry twj tso kua misncaj qha daws qhov teeb meem ntev no.
Yog tias qhov khoom siv overcurrent ntawm lub twj tso kua mis ib txwm yog "lub tais yas mov" uas tawg thaum nws ntaus rau ntawm qhov chaw tawv, ces qhov khoom siv overcurrent ua los ntawm cov khoom siv silicon carbide yog "lub tais pob zeb diamond" uas muaj qhov nyuaj thib ob tsuas yog pob zeb diamond. Thaum thauj cov khoom siv uas muaj xuab zeb, xuab zeb, thiab slag, cov khoom ntws ceev ceev ntxuav lub cev twj tso kua mis tas li, tab sis cov khoom siv silicon carbide tuaj yeem "tsis txav", nrog kev tiv thaiv kev hnav ntau dua li cov khoom siv hlau, ua rau lub twj tso kua mis siv tau ntev dua thiab txo qhov teeb meem ntawm kev nres thiab hloov cov khoom.

Ntxiv rau qhov tsis kam hnav, lub twj tso kua nplaum silicon carbide kuj tseem muaj "tiv thaiv xeb". Ntau yam khoom siv hauv kev lag luam muaj cov kua qaub thiab alkalis muaj zog, thiab cov twj tso kua nplaum hlau ib txwm yuav sai sai no xeb thiab muaj qhov. Txawm li cas los xij, silicon carbide muaj cov khoom siv tshuaj lom neeg ruaj khov, ib yam li muab ib txheej ntawm "tiv thaiv xeb" rau ntawm lub cev twj tso kua nplaum. Nws tuaj yeem tswj tau ntau yam khoom siv xeb thiab tsis txhawj txog kev raug mob los ntawm kev xau xeb.
Qhov tseem ceeb tshaj plaws yog tias phab ntsa sab hauv ntawm cov khoom siv ntws ntawm lub twj tso kua mis silicon carbide slurry yog du, ua rau tsis tshua muaj kev tiv thaiv thaum thauj cov khoom. Qhov no tsis yog tsuas yog txo cov kev siv hluav taws xob xwb, tab sis kuj txo qhov kev tso thiab thaiv cov khoom me me hauv cov khoom nruab nrab hauv lub twj tso kua mis. Txawm hais tias nws "lub cev tawv", nws tsis muaj kev txhawj xeeb thiab siv tau zoo. Hauv cov xwm txheej uas xav tau kev thauj mus los ntev thiab muaj zog ntawm cov khoom nruab nrab hnyav, nws yog tus "neeg ua haujlwm muaj peev xwm" txhim khu kev qha.
Niaj hnub no, cov twj tso kua nplaum silicon carbide tau dhau los ua cov khoom siv nyiam hauv kev lag luam xa khoom vim lawv ob qho txiaj ntsig ntawm kev hnav tsis kam thiab kev tiv thaiv corrosion. Nrog rau kev ua tau zoo, lawv muab kev tiv thaiv rau cov lag luam kom txo cov nqi thiab ua kom muaj txiaj ntsig zoo.
