Hauv ntau qhov xwm txheej kev tsim khoom lag luam, yeej ib txwm muaj qee qhov "tsis paub tab sis tseem ceeb", thiabsilicon carbide qhov hluav taws xob hauv qabyog ib qho ntawm lawv. Nws tsis yog qhov muag pom zoo li cov khoom siv loj, tab sis nws ua lub luag haujlwm ua "tus neeg saib xyuas" hauv kev xa cov khoom siv, kev sib cais cov khoom khov thiab cov kua thiab lwm yam kev sib txuas, maj mam tiv thaiv kev ua haujlwm ruaj khov ntawm kev tsim khoom.
Tej zaum ib txhia neeg yuav nug tias, vim li cas peb thiaj yuav tsum siv silicon carbide rau qhov tawm hauv qab? Qhov no pib nrog nws qhov chaw ua haujlwm. Txawm hais tias nws yog kev thauj mus los ntawm cov ntxhia thaum lub sijhawm ua kom zoo lossis kev kho cov kua corrosive hauv kev tsim tshuaj lom neeg, qhov tawm hauv qab los sib cuag nrog cov kua dej ceev ceev uas muaj cov khoom me me txhua hnub. Cov khoom khov kho hauv cov kua no zoo li ntau daim ntawv xuab zeb me me, tas li scouring qhov chaw ntawm cov khoom; Qee cov kua kuj nqa corrosiveness thiab tuaj yeem maj mam 'erode' cov khoom. Yog tias cov hlau ib txwm lossis ceramic siv ua qhov tawm hauv qab, nws yuav sai sai hnav los ntawm lossis corroded, uas tsis yog tsuas yog yuav tsum tau kaw thiab hloov pauv ntau zaus, tab sis kuj tseem yuav cuam tshuam rau kev ua haujlwm ntau lawm thiab txawm tias ua rau muaj kev phom sij rau kev nyab xeeb vim yog xau.
Thiab silicon carbide tuaj yeem ua tau raws li cov 'kev sim' no. Ua ib yam khoom siv ceramic tshwj xeeb, silicon carbide ntuj muaj kev tiv thaiv kev hnav zoo heev, thib ob tsuas yog pob zeb diamond hauv qhov nyuaj. Ntsib nrog kev kub ceev slurry lossis cov kua dej tawg, nws tuaj yeem tswj tau qhov chaw ruaj khov ntev, txo cov lej hloov pauv. Tib lub sijhawm, nws cov tshuaj lom neeg ruaj khov kuj muaj zog heev. Txawm hais tias nyob rau hauv acidic lossis alkaline corrosive ib puag ncig, nws tuaj yeem "ruaj khov zoo li Mount Tai" thiab yuav tsis yooj yim tawg los ntawm kua.
Nws yog cov yam ntxwv no uas ua rau lub hauv paus silicon carbide yog "lub luag haujlwm ruaj khov" hauv kev tsim khoom lag luam. Hauv kev lag luam xws li kev khawb av, metallurgy, thiab kev tsim kho tshuaj lom neeg uas xav tau kev tswj hwm cov khoom siv hnav thiab cov khoom siv corrosive muaj zog, nws tuaj yeem ua haujlwm tas mus li rau lub sijhawm ntev, txo qhov zaus ntawm cov khoom siv tsis ua haujlwm rau kev saib xyuas, thiab pab cov tuam txhab txo cov nqi tsim khoom. Txawm hais tias nws zoo li yog ib qho khoom me me, nws yog qhov "me me thiab zoo nkauj" no uas ua rau nws yog ib feem tseem ceeb ntawm kev ua kom muaj kev ua haujlwm zoo thiab ruaj khov ntawm kev tsim khoom lag luam.
Niaj hnub nim no, nrog rau qhov kev thov kom muaj zog thiab ruaj khov ntawm cov khoom siv hauv kev tsim khoom lag luam, kev siv cov qhov hluav taws xob hauv qab silicon carbide kuj tseem nrov zuj zus. Nws ua pov thawj nrog nws tus kheej "lub zog nyuaj" tias cov khoom siv hauv kev lag luam zoo tsis tas yuav tsum yog "high-end". Muaj peev xwm "ua siab ntev" nyob rau hauv cov haujlwm tseem ceeb yog qhov kev txhawb nqa zoo tshaj plaws rau kev tsim khoom.
