Ntawm cov kab ntau lawm ntawm lub Hoobkas, yeej ib txwm muaj qee cov khoom siv uas "nqa cov khoom hnyav" - xws li cov kav dej rau kev thauj cov hlau thiab cov thoob rau kev sib tov cov ntaub ntawv, uas yuav tsum tau daws cov khoom me me uas ntws ceev thiab cov ntaub ntawv raw tawv txhua hnub. Cov ntaub ntawv no zoo li ntau lub pob zeb me me sib tsoo, sib txhuam rau sab hauv phab ntsa ntawm cov khoom siv txhua hnub. Raws li lub sijhawm dhau mus, cov khoom siv yuav raug sib tsoo rau "mob", uas tsis yog tsuas yog yuav tsum tau kaw ntau zaus rau kev saib xyuas, tab sis kuj tseem yuav cuam tshuam rau lub suab tsim khoom. Lubsilicon carbide hnav-resistant liningyog ib daim "tsom iav tiv thaiv" hauv kev lag luam uas tsim tshwj xeeb los daws qhov teeb meem "kev hnav" no.
Tej zaum ib txhia neeg yuav xav paub, silicon carbide yog dab tsi tiag? Qhov tseeb, nws yog ib yam khoom siv inorganic uas zoo li lub pob zeb tawv grey tsaus thiab nyuaj dua li cov pob zeb ib txwm, thib ob tsuas yog pob zeb diamond hauv qhov nyuaj. Hais yooj yim, los ntawm kev ua cov khoom siv tawv no rau hauv ib daim duab uas haum rau phab ntsa sab hauv ntawm cov khoom siv, xws li daim ntawv lossis thaiv, thiab tom qab ntawd kho nws hauv thaj chaw yooj yim hnav, nws dhau los ua silicon carbide hnav-resistant lining. Nws lub luag haujlwm yog ncaj qha heev: nws "thaiv" qhov kev sib txhuam thiab kev cuam tshuam ntawm cov khoom siv rau cov khoom siv, ib yam li muab ib txheej ntawm "hnav-resistant armor" rau ntawm phab ntsa sab hauv ntawm cov khoom siv.
Ua ib tug kws tshaj lij "hnav-resistant" hauv kev lag luam, silicon carbide lining muaj ob qho zoo. Ib qho yog nws muaj zog hnav tsis kam. Ntsib nrog kev yaig ntev ntawm cov khoom siv tawv xws li thee, ore, thiab quartz xuab zeb, nws qhov chaw nyuaj rau khawb lossis tev tawm, ua rau nws hnav tsis kam ntau dua li cov hlau thiab cov khoom siv ceramics ib txwm muaj. Qhov thib ob yog hloov kho rau qhov chaw ib puag ncig hnyav. Hauv qee qhov xwm txheej tsim khoom, cov ntaub ntawv tsis yog tsuas yog sib tsoo tab sis kuj nqa qhov kub siab (xws li hauv kev lag luam smelting) lossis corrosiveness (xws li hauv kev lag luam tshuaj lom neeg). Cov ntaub ntawv hnav tsis kam ib txwm muaj peev xwm "ua tsis tiav", tab sis silicon carbide lining tuaj yeem tswj tau qhov ruaj khov hauv cov chaw ib puag ncig zoo li no, ua rau nws nyuaj rau deform vim qhov kub siab thiab corrode los ntawm cov khoom acidic thiab alkaline.
Txawm li cas los xij, txhawm rau kom 'lub tiv thaiv hnav-resistant' no ua haujlwm tau zoo, cov txheej txheem teeb tsa yog qhov tseem ceeb heev. Nws yuav tsum tau kho raws li qhov loj me thiab cov duab ntawm cov khoom siv, thiab tom qab ntawd kho rau ntawm phab ntsa sab hauv ntawm cov khoom siv hauv txoj kev tshaj lij kom ntseeg tau tias muaj kev sib haum xeeb ntawm ob qho - yog tias muaj qhov sib txawv, cov khoom siv yuav "tho qhov" thiab hnav lub cev khoom siv. Txawm hais tias kev nqis peev thawj zaug hauv silicon carbide hauv ob sab yog siab dua li cov hlau ib txwm muaj, thaum kawg, nws tuaj yeem txo qhov zaus ntawm kev saib xyuas thiab hloov khoom siv, thiab hloov chaw pab cov lag luam txuag tau ntau tus nqi.
Niaj hnub nim no, hauv cov lag luam hnav hnyav xws li kev khawb av, hluav taws xob, thiab cov ntaub ntawv tsim kho, silicon carbide hnav-resistant lining tau dhau los ua "kev xaiv" rau ntau lub tuam txhab. Nws tsis pom tseeb, tab sis nws ntsiag to tiv thaiv kev ua haujlwm ruaj khov ntawm cov khoom siv tsim khoom nrog nws tus kheej "tawv", uas tso cai rau cov khoom siv yooj yim hnav "ua haujlwm" ntev dua - qhov no yog qhov tseem ceeb ntawm nws ua tus neeg saib xyuas kev lag luam "hnav-resistant".
