Hauv cov lag luam kub siab xws li metallurgy, ceramics, thiab chemical engineering, qhov ruaj khov thiab ruaj khov ntawm cov khoom siv cuam tshuam ncaj qha rau kev ua haujlwm zoo thiab cov nqi. Raws li "caj pas" ntawm lub kaw lus combustion, lub tes tsho burner tau ntsib teeb meem ntev xws li kev cuam tshuam ntawm nplaim taws, kev xeb kub siab, thiab kev hloov pauv kub sai sai. Qhov teeb meem ntawm kev hloov pauv thiab lub neej luv luv ntawm cov tes tsho burner hlau ib txwm raug hloov pauv maj mam los ntawm ib hom khoom siv tshiab:Cov tes tsho silicon carbide (SiC) ntawm lub qhov cub tawgtab tom dhau los ua qhov nyiam tshiab hauv cov xwm txheej kub siab hauv kev lag luam vim lawv qhov kev ua tau zoo "hard core".
1, Silicon carbide: Yug los rau qhov kub siab
Silicon carbide tsis yog ib yam khoom tshiab hauv chav kuaj. Thaum ntxov li thaum kawg ntawm lub xyoo pua 19th, tib neeg tau tshawb pom cov khoom sib xyaw no uas muaj silicon thiab carbon. Nws cov qauv siv lead ua rau nws muaj peb lub zog loj:
1. Kev kub siab ua haujlwm: muaj peev xwm tswj tau lub zog ntawm 1350 ℃, deb tshaj qhov melting point ntawm cov hlau ib txwm muaj;
2. Kev hnav tsis kam: Ntsib nrog qhov chaw hnav siab, nws lub neej ntev dua li cov ntaub ntawv ib txwm muaj ntau zaus;
3. Kev tiv thaiv corrosion: Nws muaj zog tiv thaiv acidic thiab alkaline ib puag ncig thiab molten hlau corrosion.
Cov yam ntxwv no ua rau silicon carbide yog qhov kev xaiv zoo tshaj plaws rau cov ntaub ntawv siv rau lub tes tsho hlawv, tshwj xeeb tshaj yog rau cov khoom siv hlawv uas xav tau kev raug hluav taws kub ntev.
2, Peb qhov zoo tshaj plaws ntawm silicon carbide burner tes tsho
Piv nrog cov hlau ib txwm muaj los yog cov tes tsho ceramic burner, qhov zoo ntawm cov silicon carbide version pom tseeb:
1. Ua kom lub neej ntev dua ob npaug
Lub tes tsho hlau hlawv yog qhov yooj yim rau oxidation thiab softening ntawm qhov kub siab, thaum lub zog ruaj khov ntawm silicon carbide ntev nws lub neej kev pabcuam los ntawm 3-5 zaug, txo qhov zaus ntawm kev kaw thiab hloov pauv.
2. Kev txuag hluav taws xob thiab kev txhim kho kev ua haujlwm zoo
Lub thermal conductivity ntawm silicon carbide yog ntau zaus ntawm cov ceramics ib txwm muaj, uas tuaj yeem hloov pauv cua sov sai sai, txhim kho kev ua haujlwm ntawm roj combustion, thiab txo kev siv hluav taws xob.
3. Kev saib xyuas yooj yim
Tsis yooj yim hnav, tsis yooj yim xeb, thiab tsis yooj yim kub, tsuas yog xav tau kev saib xyuas txhua hnub yooj yim xwb, txo cov nqi saib xyuas.
3. Cov lag luam twg xav tau nws ntau dua?
1. Lub qhov cub ua los ntawm cov av nplaum: Haum rau cov chaw ua kom ci ntsa iab saum 1300 ℃
2. Kev kho cua sov hlau: tiv taus cov hlau yaj thiab cov slag erosion
3. Kev hlawv pov tseg: tiv taus qhov muaj zog corrosiveness ntawm chlorine uas muaj cov roj pov tseg
4. Lub cub tawg iav: tsim nyog rau kev ua haujlwm ruaj khov mus sij hawm ntev hauv qab huab cua alkaline
4. Cov lus qhia siv
Txawm hais tias kev ua tau zoo ntawm lub tes tsho silicon carbide burner muaj zog, kev siv kom raug tseem ceeb heev:
1. Tsis txhob muaj kev sib tsoo thaum lub sijhawm teeb tsa kom tiv thaiv cov kab nrib pleb zais cia
2. Nws raug pom zoo kom nce qhov kub ib kauj ruam zuj zus thaum lub sijhawm pib txias
3. Tshem tawm cov txheej coking ntawm qhov chaw tas li thiab khaws lub nozzle kom tsis txhob muaj dab tsi thaiv
Ua ib lub tuam txhab muab kev pabcuam thev naus laus zis uas koom nrog kev lag luam ntawm cov khoom siv refractory, peb ib txwm ua tib zoo saib xyuas kev siv thiab kev hloov pauv ntawm cov khoom siv thev naus laus zis tshiab. Kev txhawb nqa ntawm silicon carbide burner tes tsho tsis yog tsuas yog kev txhim kho cov khoom siv xwb, tab sis kuj yog kev teb rau qhov kev thov rau "kev ua haujlwm zoo dua, txuag hluav taws xob, thiab txhim khu kev qha" kev tsim khoom lag luam. Yav tom ntej, peb yuav txuas ntxiv mus txhim kho cov txheej txheem khoom thiab pab kom ntau lub tuam txhab siv cov kev daws teeb meem kub siab uas "ua haujlwm ntev thiab pheej yig dua".
Pab neeg ua haujlwm tshaj lij ntawm Shandong Zhongpeng tuaj yeem muab cov lus qhia xaiv thiab kev txhawb nqa rau koj. Txais tos rautuaj xyuas pebrau cov kev daws teeb meem tshwj xeeb.
