Hauv cov chaw ua haujlwm tsim khoom ntawm cov lag luam xws li ceramics thiab electronic ceramics, cov qhov cub kub siab zoo li "tus kws ua haujlwm kub hnyiab" uas ntsiag to, thiab lub hauv paus tseem ceeb uas txhawb nqa kev ua haujlwm ruaj khov ntawm "chav hluav taws" no yog lub kem silicon carbide kiln. Nws yuav zoo li qub, tab sis nws nqa qhov hnyav hauv lub qhov cub hauv qhov kub siab ntawm ntau txhiab degrees, tiv thaiv kev nyab xeeb thiab kev ruaj khov ntawm kev tsim khoom, thiab tuaj yeem hu ua "steel backbone" ntawm lub kaw lus kiln.
Muaj ntau tus neeg yuav tsis paub txog lo lus'silicon carbide'. Hais yooj yim, silicon carbide yog cov khoom siv ceramic ua tau zoo uas yog cov khoom siv dag zog, sib xyaw ua ke qhov kub thiab txias ntawm cov khoom siv ceramic nrog cov hlau muaj zog. Cov kem kiln ua los ntawm nws yog ntuj tsim nrog "muaj peev xwm zoo heev" ntawm "kev kub thiab hnav tsis kam". Thaum ua haujlwm hauv lub kiln, qhov kub thiab txias sab hauv feem ntau ncav cuag tshaj 1200 ℃, thiab cov khoom siv hlau ib txwm tau yaj thiab deformed. Txawm li cas los xij, silicon carbide kem tuaj yeem tswj tau qhov ruaj khov hauv cov chaw ib puag ncig hnyav, tsis muaj khoov lossis tawg, thiab txhawb nqa cov rooj tog kiln thiab cov khoom kom ua tiav.
Ntxiv rau qhov ua kom kub tsis kam, cov kem silicon carbide kiln kuj muaj ob qho "peev xwm" zoo heev. Ib qho yog nws qhov ua kom corrosion muaj zog. Cov pa roj kub thiab cov khoom siv hauv lub kiln tuaj yeem tsim cov tshuaj corrosive, thiab cov khoom siv ib txwm yuav maj mam hnav tawm tom qab kev sib cuag ntev. Txawm li cas los xij, cov khoom siv tshuaj lom neeg ntawm silicon carbide ruaj khov heev, uas tuaj yeem tiv taus corrosion thiab ntev nws lub neej kev pabcuam; Qhov thib ob yog qhov ua tau zoo thermal conductivity, uas tuaj yeem pab faib qhov kub thiab txias hauv lub kiln, zam kev kub dhau lossis txias dhau. Qhov no yog qhov tseem ceeb rau kev ua kom zoo ntawm cov khoom hlawv - tom qab tag nrho, txawm tias nws yog cov khoom siv ceramic lossis cov khoom siv hluav taws xob, kev tswj qhov kub thiab txias yog qhov tseem ceeb rau qhov zoo.
Tej zaum yuav muaj ib txhia neeg nug tias, vim li cas ho tsis xaiv lwm yam khoom siv los ua cov kem kiln? Qhov tseeb, cov cib av nplaum ib txwm muaj lossis cov kem hlau feem ntau yuav tawg thiab puas tsuaj lossis muaj lub neej ua haujlwm luv luv hauv qhov chaw kub siab, xav tau hloov pauv ntau zaus. Qhov no tsis yog tsuas yog ua rau cov nqi tsim khoom ntau ntxiv xwb tab sis kuj tseem yuav cuam tshuam rau kev nce qib ntawm kev tsim khoom. Lub kem kiln silicon carbide, nrog nws cov txiaj ntsig kev ua tau zoo, tuaj yeem txo qhov zaus txij nkawm, txhim kho kev ua haujlwm tas mus li ntawm lub kiln, thiab txuag lub sijhawm thiab cov nqi rau cov lag luam. Qhov no kuj yog qhov laj thawj tseem ceeb vim li cas nws thiaj li tau dhau los ua cov khoom txhawb nqa zoo tshaj plaws rau cov kilns kub siab niaj hnub no.
Ua ib tug "neeg tseem ceeb tom qab qhov xwm txheej" hauv lub kaw lus kiln, cov kem silicon carbide kiln pab txhawb nqa kev yug los ntawm ntau yam khoom lag luam nrog lawv cov kev ua tau zoo. Nws qhov muaj nyob tsis yog tsuas yog qhia txog kev nce qib ntawm cov thev naus laus zis tshiab, tab sis kuj pom kev txhim kho ntawm kev tsim khoom ib txwm mus rau kev ua haujlwm siab, kev ruaj khov, thiab kev txuag hluav taws xob. Yav tom ntej, nrog rau kev ua kom zoo dua ntawm cov thev naus laus zis khoom siv, cov kem silicon carbide kiln yuav ua lub luag haujlwm tseem ceeb hauv cov teb kev lag luam kub siab dua, txhaj tshuaj muaj zog rau hauv kev txhim kho kev lag luam.
