Hauv thaj chaw tseem ceeb ntawm ntau lub qhov cub kub siab, yeej ib txwm muaj ib qho khoom tsis pom tseeb tab sis tseem ceeb uas ntsiag to tiv taus qhov kev sim ntawm hluav taws kub thiab lub nra hnyav, uas yog qhovsilicon carbide kem roller rod.Ua ib yam khoom tseem ceeb hauv kev lag luam ceramics, silicon carbide column rollers tau dhau los ua "tus neeg ua si tus qauv" hauv ntau qhov xwm txheej kub siab vim lawv qhov kev ua tau zoo heev, txhawb kev ua haujlwm ruaj khov ntawm ntau kab ntau lawm tseem ceeb.
Tej zaum ib txhia neeg yuav xav tsis thoob tias vim li cas silicon carbide column rollers thiaj li sawv tawm ntawm cov khoom siv txhawb nqa thiab kis tau siv hauv cov cub tawg? Qhov no pib nrog nws cov khoom siv. Silicon carbide nws tus kheej yog cov khoom siv "ruaj khov", nrog qhov nyuaj thib ob tsuas yog pob zeb diamond, nyuaj dua li cov hlau ib txwm thiab cov khoom siv ceramic ib txwm muaj. Nws tsis ntshai kev hnav thiab rhuav lossis pob hauv kev siv txhua hnub, thiab tuaj yeem khaws nws cov duab qub thiab kev ua tau zoo txawm tias thaum sib cuag thiab sib txhuam nrog ntau yam khoom siv ntev, yam tsis yooj yim poob lossis puas tsuaj.
Lub pillar roller ua los ntawm silicon carbide tau coj qhov "ruaj khov" no mus rau qhov kawg. Qhov tshwj xeeb tshaj plaws yog nws qhov kub thiab txias siab. Hauv qhov kub siab ntawm lub cub tawg ntawm ntau txhiab degrees Celsius, ntau yam khoom siv hlau twb tau deformed thiab tsis ua haujlwm, thiab cov khoom siv ceramic ib txwm muaj kuj yooj yim tawg thiab puas tsuaj. Txawm li cas los xij, silicon carbide column rollers tuaj yeem "lo rau lawv cov ncej" thiab tiv taus qhov kub siab ntev. Qhov cwj pwm no ua rau lawv txhim khu kev qha hauv kev tsim khoom kub siab.
Ntxiv rau qhov ua tau zoo ntawm qhov kub thiab txias thiab hnav tsis kam, cov menyuam silicon carbide column kuj muaj ob qho zoo tseem ceeb. Ua ntej, nws muaj kev ruaj khov heev. Hauv qab ob qhov kev sim ntawm qhov kub thiab txias thiab hnyav, nws tuaj yeem ua lub hauv paus rau kev nqa khoom thiab kev txhawb nqa, nrog rau lub menyuam kom ua tiav kev thauj khoom du. Nws tuaj yeem khiav tau ntev yam tsis muaj khoov lossis deformation, ua kom ntseeg tau tias kev ua haujlwm tas mus li ntawm cov kab ntau lawm mus rau qhov ntau tshaj plaws thiab txo qhov poob ntawm lub sijhawm tsis ua haujlwm los ntawm kev ua tsis tiav ntawm cov khoom. Qhov thib ob, nws muaj kev tiv thaiv corrosion zoo heev. Txawm hais tias nws yog huab cua acidic hauv lub qhov cub lossis kev sib cuag nrog qee cov khoom siv alkaline, nws yuav tsis ua rau xeb, thiab nws lub neej ua haujlwm zoo dua li cov khoom ib txwm muaj xws li alumina ceramic rods. Nws kuj tseem tuaj yeem pab cov tuam txhab txuag tau ntau tus nqi rau kev hloov khoom.
Txawm hais tias cov duab ntawm cov silicon carbide pillar roller tsis nyuaj, muaj ntau yam ntsiab lus zais cia hauv nws cov txheej txheem tsim khoom. Cov silicon carbide column rollers zoo yuav tsum siv cov khoom siv silicon carbide ntshiab siab ua ntej, dhau qhov sib piv thiab kev ua molding, thiab tom qab ntawd xa mus rau lub cub tawg kub siab rau sintering, cia cov silicon carbide me me sib xyaw ua ke thiab tsim cov qauv ceramic ntom thiab sib xws. Tom qab ntawd, lawv yuav tsum tau polished zoo kom ntseeg tau tias qhov loj me thiab du nto, txhawm rau ua kom tau raws li qhov xav tau ntawm cov cub tawg sib txawv. Txhua txoj kev xav tau kev tswj hwm nruj kom ntseeg tau tias cov khoom kawg muaj lub zog siab, tawv, thiab ruaj khov, thiab tuaj yeem tiv taus cov kev sim hnyav ntawm kev tsim khoom lag luam.
Niaj hnub no, cov menyuam roj hmab silicon carbide twb tau nkag mus rau ntau qhov chaw lag luam tseem ceeb. Hauv cov qhov cub hluav taws kub ntawm cov khoom siv ceramic thiab cov khoom siv ceramic huv, nws maj mam nqa thiab thauj cov khoom siv ceramic, pab kom cov khoom siv ceramic zoo nkauj ib qho los ntawm ib qho; Hauv cov kab ntau lawm ntawm cov roj teeb lithium thiab photovoltaics hauv thaj chaw ntawm lub zog tshiab, nws ntsiag to siv zog hauv cov txheej txheem sintering kub siab los tiv thaiv kev tsim khoom zoo ntawm cov khoom siv roj teeb thiab photovoltaic silicon wafers; Tsis tas li ntawd, nws tuaj yeem pom hauv cov xwm txheej tsim khoom uas xav tau qhov chaw kub siab xws li cov ntaub ntawv sib nqus thiab kev kho cua sov iav. Nws tuaj yeem hais tias txhua qhov chaw muaj qhov kub siab thiab hnyav thauj khoom xav tau kev tsim khoom lag luam, muaj "kev txhawb nqa nyuaj" ntawm silicon carbide kem rollers.
Nrog rau kev txhim kho ntawm kev tsim khoom lag luam siab thiab ua haujlwm tau zoo, qhov xav tau rau cov khoom siv kub siab kub tas li nce ntxiv. Silicon carbide pillar rollers, nrog lawv cov txiaj ntsig kev ua tau zoo tsis tuaj yeem hloov pauv, tsis yog tsuas yog ua tau raws li cov kev xav tau ntawm ntau yam lag luam tam sim no, tab sis kuj hloov kho rau qhov kev txhim kho ntawm kev tsim khoom siab yav tom ntej. Raws li ib tug tswv cuab koom nrog tob hauv kev lag luam ntawm silicon carbide industrial ceramics, peb ib txwm tsom mus rau kev tshawb fawb thiab kev tsim khoom ntawm silicon carbide column rollers, siv cov khoom zoo heev los pab txhim kho qhov zoo thiab kev ua haujlwm ntawm cov kab ntau lawm hauv ntau yam lag luam, thiab ntxiv cov cib thiab cov vuas rau kev txhim kho kev lag luam nrog "hard core ceramics".
