Hauv kev tsim khoom lag luam niaj hnub no, cov kav dej zoo li "cov hlab ntsha" ntawm tib neeg lub cev, ua txoj haujlwm tseem ceeb ntawm kev thauj mus los kub thiab corrosive. Lubsilicon carbide (SiC) txheejthev naus laus zis zoo li muab ib txheej ntawm cov cuab yeej ua haujlwm siab rau ntawm cov "cov hlab ntsha", ua rau cov kav dej muaj zog dua, tiv taus xeb, thiab tiv taus kub siab. Cov txheej txheem tiv thaiv yooj yim no tiv thaiv kev ua haujlwm ruaj khov ntawm cov kav dej li cas?
1, Cov khoom siv: Lub "txuj ci tseem ceeb" ntawm silicon carbide
Silicon carbide yog hu ua "industrial black diamond", thiab nws cov qauv atomic yog ib lub network crystal peb-seem uas muaj cov bonds ntawm silicon thiab carbon, muab nws nrog peb yam khoom tseem ceeb:
1. Qhov nyuaj ntawm pob zeb diamond (qhov thib ob tsuas yog pob zeb diamond hauv Mohs hardness), uas tuaj yeem tiv taus kev puas tsuaj ntawm cov khoom me me
2. Super muaj zog tshuaj inertness, resistant rau corrosive media xws li acids, bases, thiab ntsev
3. Kev ruaj khov zoo heev, tswj kev ruaj khov ntawm cov qauv txawm tias kub siab ntawm 1350 ℃
Cov khoom siv no ua rau nws yog cov khoom siv tiv thaiv zoo tshaj plaws rau kev ua haujlwm hnyav.
2, Kev tiv thaiv mechanism: Triple defense system
Thaum lub silicon carbide lining lo rau ntawm phab ntsa sab hauv ntawm cov kav dej, nws tsim ntau txheej kev tiv thaiv:
Txheej txheej thaiv lub cev: cov pob zeb silicon carbide ntom ntom ncaj qha cais cov khoom nruab nrab los ntawm kev sib cuag nrog lub cev hlau
Cov txheej txheem tshuaj lom neeg ruaj khov: tsim cov zaj duab xis oxide tiv thaiv los ntawm kev ua kom tsis muaj zog, tiv taus kev xeb
Cov txheej txheem tiv thaiv sib xyaw ua ke no tso cai rau cov kav dej kom tswj tau qhov kev ua haujlwm zoo txawm tias nyob rau hauv cov xwm txheej hnyav xws li xeb muaj zog, hnav siab, thiab qhov chaw kub siab.
3, Qhov zais cia rau kev ua haujlwm mus sij hawm ntev: kev kho tus kheej
Cov kev tshawb fawb tshiab kawg tau pom tias silicon carbide muaj peev xwm sib xyaw ua ke ntawm qhov chaw tshwj xeeb hauv qab cov xwm txheej ua haujlwm tshwj xeeb. Thaum muaj kev puas tsuaj me me, cov silicon atoms dawb ntawm qhov chaw ntawm cov khoom yuav rov ua dua tshiab hauv qhov chaw kub siab, kho qee qhov tsis zoo ntawm qhov chaw. Qhov no ua rau lub neej ua haujlwm ntawm lub hauv pem teb ntev dua thiab txo qhov zaus txij nkawm.
4, Cov txiaj ntsig tsis pom: tus nqi tag nrho ntawm lub neej
Piv nrog cov ntaub ntawv ib txwm muaj, silicon carbide lining coj cov txiaj ntsig kev lag luam zais cia tab sis muaj txiaj ntsig zoo rau cov lag luam kev lag luam los ntawm kev txo cov naj npawb ntawm kev kaw rau kev saib xyuas, txo qhov kev pheej hmoo ntawm kev ua qias tuaj nruab nrab, thiab txuas ntxiv lub voj voog hloov pauv. Tshwj xeeb tshaj yog nyob rau hauv cov teb ntawm cov tshuaj zoo thiab kev npaj cov khoom siv hluav taws xob tshiab, qhov tseem ceeb ntawm kev lees paub cov khoom siv huv si yog qhov nyuaj dua los ntsuas nrog cov ntaub ntawv yooj yim.
Nrog rau kev txhim kho ntawm cov thev naus laus zis hauv kev lag luam kom ua haujlwm tau zoo dua thiab tsis ua rau ib puag ncig puas tsuaj, cov thev naus laus zis hauv daim ntaub silicon carbide tau hloov zuj zus los ntawm "kev tiv thaiv tshwj xeeb" mus rau "kev teeb tsa tus qauv". Cov kev daws teeb meem no uas sib xyaw cov ntaub ntawv tshawb fawb thiab kev txawj ntse hauv kev tsim kho ua rau "txoj kab cawm siav" ntawm kev lag luam niaj hnub no thiab dhau los ua kev txhawb nqa tseem ceeb rau kev txhim kho qhov zoo thiab kev ua haujlwm ntawm cov txheej txheem kev lag luam.
