Raws li ib yam tshiab ntawm inorganic non-metallic khoom, atmospheric siab sintered silicon carbide ceramic khoom tau lug siv nyob rau hauv kiln, desulfurization thiab ib puag ncig tiv thaiv, tshuaj lom neeg kev lag luam, hlau, aerospace thiab lwm yam teb. Txawm li cas los xij, daim ntawv thov ntawm atmospheric siab sintered silicon carbide ceramic khoom yog tseem nyob rau hauv lub zoo tib yam theem, thiab muaj ib tug loj tus naj npawb ntawm daim ntawv thov teb uas tsis tau loj-scale kev loj hlob, thiab kev lag luam loj loj. Raws li cov chaw tsim khoom ntawm atmospheric siab sintered silicon carbide ceramics, peb yuav tsum txuas ntxiv ntxiv dag zog rau kev lag luam kev loj hlob, tsim nyog txhim kho lub peev xwm ntau lawm, thiab nyob rau hauv ib txoj hauj lwm siab dua hauv daim ntawv thov tshiab ntawm silicon carbide ceramics.
Cov dej ntws ntawm kev lag luam feem ntau yog atmospheric siab sintered silicon carbide smelting thiab nplua hmoov ntau lawm. Cov ntu ntu ntu ntawm kev lag luam npog ntau yam, suav nrog txhua qhov kev lag luam uas xav tau cov khoom siv kub, hnav thiab corrosion resistant.
(1) Upstream kev lag luam
Silicon carbide hmoov thiab hlau silicon hmoov yog cov ntaub ntawv tseem ceeb ntawm kev lag luam. Tuam Tshoj tus silicon carbide ntau lawm pib nyob rau hauv 1970s. Tom qab ntau tshaj 40 xyoo ntawm txoj kev loj hlob, kev lag luam tau los ntev. Smelting thev naus laus zis, cov cuab yeej tsim khoom thiab cov ntsuas kev siv hluav taws xob tau mus txog qib zoo. Ze li 90% ntawm lub ntiaj teb silicon carbide yog tsim nyob rau hauv Suav teb. Nyob rau hauv xyoo tas los no, tus nqi ntawm silicon carbide hmoov tsis tau hloov ntau; Hlau silicon hmoov yog tsim nyob rau hauv Yunnan, Guizhou, Sichuan thiab lwm thaj tsam sab hnub poob. Thaum dej thiab hluav taws xob muaj ntau nyob rau lub caij ntuj sov, tus nqi ntawm cov hlau silicon hmoov kuj pheej yig, thaum lub caij ntuj no, tus nqi yog me ntsis siab dua thiab tsis hloov pauv, tab sis feem ntau kuj ruaj khov. Tus nqi hloov pauv ntawm cov khoom siv raw hauv kev lag luam nce toj muaj qee yam cuam tshuam rau cov khoom lag luam pricing txoj cai thiab cov nqi ntawm cov lag luam hauv kev lag luam.
(2) downstream kev lag luam
Lub downstream ntawm kev lag luam yog silicon carbide ceramic khoom thov kev lag luam. Silicon carbide ceramic khoom tsis yog tsuas yog ntau yam, tab sis kuj ua tau zoo heev. Dav siv nyob rau hauv kev tsim kho, huv si ceramics, niaj hnub ceramics, sib nqus cov ntaub ntawv, iav-ceramics, industrial furnaces, tsheb, twj, boilers, fais fab chaw nres tsheb, ib puag ncig tiv thaiv, ntawv ua, roj av, metallurgy, tshuaj lom neeg kev lag luam, machinery, aerospace thiab lwm yam teb. Nrog rau kev ua tau zoo tshaj ntawm silicon carbide ceramic khoom tau lees paub los ntawm ntau thiab ntau kev lag luam, daim ntawv thov ntau ntawm silicon carbide ceramic khoom yuav ntau thiab ntau dua. Kev noj qab haus huv, kev txhawb nqa thiab kev loj hlob sai ntawm kev lag luam hauv qab yuav muab kev lag luam dav dav rau kev lag luam thiab txhawb kev loj hlob ntawm kev lag luam tag nrho.
Nrog rau daim ntawv thov dav ntawm atmospheric siab sintered silicon carbide ceramic khoom, kev lag luam xav tau kuj nce, attracting ib feem ntawm lub peev mus rau hauv lub teb ntawm silicon carbide ceramic manufacturing. Ntawm qhov tod tes, qhov ntsuas ntawm silicon carbide kev lag luam txuas ntxiv nthuav dav, thiab cov khoom tsim hauv cheeb tsam yog maj mam tawg mus rau txhua qhov chaw ntawm lub tebchaws. Nyob rau hauv ib lub sij hawm luv luv ntawm kaum xyoo, kev lag luam silicon carbide tau tsim sai heev. Ntawm qhov tod tes, thaum qhov ntsuas ntawm kev lag luam txuas ntxiv nthuav dav, nws tseem tab tom ntsib qhov tshwm sim ntawm kev sib tw vicious. Vim tias qhov pib nkag qis ntawm kev lag luam, tus naj npawb ntawm cov tuam txhab tsim khoom loj, qhov loj ntawm cov lag luam txawv, thiab cov khoom zoo tsis sib xws.
Qee lub tuam txhab loj tsom mus rau kev txhim kho thev naus laus zis thiab kev tshawb fawb thiab kev tsim khoom tshiab; Cov nplai txuas ntxiv nthuav dav, thiab kev pom thiab kev cuam tshuam ntawm lub tuam txhab tau nce ib hnub dhau ib hnub. Nyob rau tib lub sijhawm, ntau thiab ntau cov tuam txhab me me tuaj yeem tso siab rau tus nqi qis los tuav cov xaj, ua rau muaj kev sib tw tsis zoo hauv kev lag luam. Kev sib tw hauv kev lag luam yog qhov hnyav, thiab kev lag luam tseem yuav qhia txog kev sib txawv ntawm polarization.
