Hauv cov ces kaum zais ntawm kev tsim khoom lag luam, muaj ntau yam khoom siv ua haujlwm ntsiag to uas txhawb nqa kev ua haujlwm du ntawm tag nrho cov saw hlau kev lag luam, thiab cov twj tso kua mis slurry yog ib qho tseem ceeb ntawm nws. Hauv tsev neeg twj tso kua mis slurry, daim duab ntawm cov khoom siv silicon carbide tab tom dhau los ua "lub zog tseem ceeb" nyob rau hauv kev hnav siab thiab kev xeb siab nrog nws cov txiaj ntsig kev ua tau zoo tshwj xeeb. Rau cov pej xeem feem ntau, lo lus 'silicon carbide slurry twj tso kua mis' tej zaum yuav tsis paub, tab sis nws twb tau koom ua ke tob rau hauv ntau qhov chaw xws li kev khawb av, kev sib xyaw hlau, thiab kev tsim tshuaj lom neeg, dhau los ua cov khoom siv tseem ceeb rau kev thauj mus los 'cov xov xwm nyuaj' hauv kev tsim khoom lag luam.
Yuav kom nkag siab txog tus nqi ntawmsilicon carbide slurry twj tso kua mis, ib tug yuav tsum xub nkag siab tias qhov kev ua haujlwm uas lawv ntsib yog qhov nyuaj npaum li cas. Cov slag slurry uas yuav tsum tau thauj mus rau hauv kev tsim khoom lag luam feem ntau yog sib xyaw nrog cov khoom tawv lossis cov khoom phom sij xws li xuab zeb, slag, thiab cov kua corrosive. Cov khoom siv twj tso kua mis ib txwm muaj feem yuav hnav, xeb, xau, thiab lwm yam teeb meem hauv ib puag ncig zoo li no. Tsis yog lawv yuav raug kaw tas li rau kev saib xyuas xwb, tab sis lawv kuj tseem yuav cuam tshuam rau kev nyab xeeb thiab kev ua haujlwm ntawm tag nrho cov txheej txheem tsim khoom. Silicon carbide, cov khoom siv inorganic tsis yog hlau uas tsim los ntawm qhov kub siab los ntawm silicon thiab cov ntsiab lus carbon, muaj cov yam ntxwv nyuaj ntawm "kev hnav tsis kam, kev xeb tsis kam, thiab kev kub siab", uas zoo meej rau cov kev xav tau nyuaj ntawm kev thauj mus los slag slurry. Kev siv silicon carbide rau cov khoom tseem ceeb ntawm cov twj tso kua mis slurry zoo li muab ib txheej ntawm "pob zeb diamond armor" rau ntawm lub cev twj tso kua mis, tso cai rau nws kom ruaj khov "ua haujlwm" nyob rau hauv cov xwm txheej ua haujlwm hnyav.
Qhov zoo ntawm cov twj tso kua silicon carbide slurry yog los ntawm cov khoom tshwj xeeb ntawm cov khoom siv silicon carbide. Tsis zoo li cov khoom siv hlau ib txwm muaj uas yooj yim hnav thiab xeb, silicon carbide muaj qhov nyuaj thib ob tsuas yog pob zeb diamond, thiab nws qhov kev tiv thaiv hnav ntau dua li cov hlau ib txwm muaj. Ntsib nrog kev sib xyaw siab thiab kev nyuaj siab slurry erosion, nws tuaj yeem tiv taus kev sib tsoo me me thiab ntev lub neej ntawm lub twj tso kua mis lub cev; Tib lub sijhawm, nws muaj kev ruaj khov tshuaj zoo heev, ua rau nws nyuaj rau acidic, alkaline, lossis corrosive media kom corrode nws, zam kev puas tsuaj rau lub cev twj tso kua mis thiab qhov nruab nrab xau los ntawm corrosion; Tsis tas li ntawd, qhov kub siab tiv taus ntawm silicon carbide kuj zoo heev. Hauv qhov xwm txheej ntawm kev thauj mus los slurry kub siab, nws tseem tuaj yeem tswj tau cov qauv ruaj khov thiab kev ua tau zoo, thiab yuav tsis deform lossis tsis ua haujlwm vim kub siab.
Tej zaum yuav muaj ib txhia neeg xav tias seb lub twj "hardcore" no puas yuav nyuaj thiab nyuaj dhau? Qhov tseeb, lub twj tso kua mis silicon carbide slurry no yog tsim los kom muaj kev sib npaug ntawm kev ua tau zoo thiab kev siv tau yooj yim, nrog rau cov qauv me me thiab kev teeb tsa yooj yim, thiab tuaj yeem siv tau yam tsis tas yuav muaj cov chaw txhawb nqa nyuaj. Tib lub sijhawm, nws muaj suab nrov tsawg thiab kev siv hluav taws xob tsawg, uas tsis yog tsuas yog txhim kho kev ua haujlwm ntau lawm xwb tab sis kuj pab cov lag luam ua tiav cov hom phiaj txuag hluav taws xob thiab txo kev siv hluav taws xob. Rau cov lag luam, kev xaiv cov twj tso kua mis silicon carbide slurry tsis yog txhais tau tias txo lub sijhawm thiab cov nqi kho khoom siv, txo qhov kev pheej hmoo ntawm kev cuam tshuam kev tsim khoom, tab sis kuj tseem txhim kho kev ua haujlwm tag nrho ntawm lub lag luam los ntawm kev ua kom muaj kev sib txuas ntawm cov txheej txheem tsim khoom los ntawm kev ua haujlwm ruaj khov.
Nrog rau kev txhim kho tas mus li ntawm cov thev naus laus zis kev lag luam, qhov kev xav tau ntawm kev ua haujlwm rau cov khoom siv kuj tseem nce ntxiv tas li, thiab cov xwm txheej ntawm daim ntawv thov ntawm cov twj tso kua mis silicon carbide slurry kuj nthuav dav tas li. Los ntawm kev thauj mus los ntawm cov tailings mining mus rau kev kho cov khib nyiab metallurgical, los ntawm kev thauj mus los ntawm cov tshuaj lom neeg mus rau kev kho cov dej khib nyiab ib puag ncig, nws ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw nrog kev hloov pauv zoo heev. Yav tom ntej, nrog kev txhim kho ntxiv ntawm cov thev naus laus zis ua cov khoom siv silicon carbide thiab kev tsim kho tshiab tas mus li hauv kev tsim lub cev twj tso kua mis, cov twj tso kua mis silicon carbide slurry yuav txuas ntxiv mus rau kev ua haujlwm zoo dua, kev txuag hluav taws xob, thiab kev txawj ntse, muab kev txhawb nqa zoo dua rau kev txhim kho zoo ntawm kev tsim khoom lag luam.
Qhov "hardcore conveyor" no zais cia rau hauv cov ntsiab lus kev lag luam, txawm hais tias tsis tshua pom hauv pej xeem lub qhov muag, ntsiag to tiv thaiv kev ua haujlwm zoo ntawm kev tsim khoom lag luam nrog nws cov txiaj ntsig kev ua tau zoo. Nws tsis yog tsuas yog tus sawv cev ntawm kev siv cov ntaub ntawv silicon carbide, tab sis kuj yog lub microcosm ntawm kev txhim kho thiab rov ua dua ntawm cov khoom siv kev lag luam, ua tim khawv rau cov txheej txheem kev txhim kho ntawm kev siv tshuab kev lag luam los ntawm "ua kom tau raws li qhov xav tau" mus rau "nrhiav kev ua tau zoo".
