Hauv kev lag luam xws li tshuaj lom neeg, roj av, roj av, kev tiv thaiv ib puag ncig, thiab kev kho dej,alumina ceramic pobyog dav siv raws li ntauwd packing, catalyst txhawb pob, thiab inert ceramic pob. Txawm li cas los xij, hauv kev yuav khoom tiag tiag, qhov tseem ceeb tsis zoo rau kev sib txuam nrog kev ua haujlwm feem ntau tsis pom zoo, ua rau muaj teeb meem xws li kev poob siab tsis zoo, tus nqi tawg siab, kev ua haujlwm tsis ruaj khov ntawm chav tsev, thiab txawm tias nquag kaw.
I. Qhia kom meej cov ntawv thov: Cov ntawv thov sib txawv yuav tsum muaj cov khoom sib txawv ntawm Alumina Ceramic
1. Catalyst Support Balls
Lub luag haujlwm tseem ceeb:
* Muab faib ua pa thiab kua
* Txhawb lub txaj sab sauv catalyst
* Txo kev poob siab thiab tiv thaiv cov catalyst
Xaiv tsom xam:
* Siab compressive zog
* Kev faib tawm meej
* Tsawg tawg tus nqi thiab ruaj khov ntev - lub sijhawm ua haujlwm
Kev siv ntau: Hydrogenation units, hloov kho chav tsev, ammonia synthesis, PTA, sulfur rov qab, thiab lwm yam.
2. Inert Packing Ceramic Balls
Kev siv tseem ceeb:
Hauv qab filling ntawm towers
Txhim kho cov dej faib
Tiv thaiv cov tais lossis cov khoom siv
Xaiv tsom xam:
Tsim nyog packing ceev
Zoo thermal stability
Qhov sib npaug ntawm cov nqi thiab kev ua haujlwm
Kev siv ntau: Distillation kab, kab nqus, desulfurization thiab denitrification units.
3. Kev ua haujlwm tshwj xeeb rau cov pob zeb ceramic (High Temperature / High Pressure / Strong Corrosion)
Nyob rau hauv siab -kub pyrolysis, muaj zog acid / alkali, los yog siab - ib puag ncig siab, cov pob ceramic zoo tib yam tsis tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev.
Xaiv tsom xam:
Ntau dua alumina cov ntsiab lus
Tsawg impurities
Zoo heev thermal shock kuj
II. Cov Txheej Txheem Tseem Ceeb rau Alumina Ceramic Pob Xaiv
1. Alumina Cov ntsiab lus
92%: Lub hom phiaj dav dav, tus nqi siab -kev ua tau zoo
95%–99%: Siab-kawg kev ua haujlwm, zoo hnav tsis kam, siab tsis kam, thiab corrosion kuj
Kev pom zoo: Rau siab - kub, siab - siab, los yog ntev - lub voj voog ua haujlwm → ua qhov tseem ceeb dua cov qauv qauv.
2. Compressive zog
Compressive zog ncaj qha mus rau:
Seb nws yuav pulverize thaum lub sijhawm ua haujlwm ntev -
Seb nws yuav ua rau txaj txaj
Lus Cim: Tsis yog "qhov loj dua qhov zoo dua," tab sis nws yuav tsum phim lub pob kab thiab cov qauv siv.
3. Pob taub thiab muab qhab nia tsim
Siv ntau gradations
Me me nyob rau sab saum toj, loj dua hauv qab, tsim ib lub txaj ruaj khov
Txo kev poob siab thiab txhim kho kev ua haujlwm zoo
4. Kev nqus dej thiab ntom ntom
Kev nqus dej tsawg → denser qauv
High ceev → muaj zog tiv taus yaig thiab pulverization
Qhov no tseem ceeb tshwj xeeb tshaj yog rau cov khoom siv ua haujlwm tsis tu ncua.
5. Tshuaj Stability
Nyob rau hauv acidic, sulfur-muaj, los yog aqueous systems, tshuaj stability ntawm cov ceramic pob txiav txim lawv lub neej kev pab cuam.
Alumina ceramic pob yuav zoo li "cov khoom siv yooj yim," tab sis qhov tsim nyog ntawm lawv cov kev xaiv feem ntau cuam tshuam ncaj qha:
Cov cuab yeej ua haujlwm ruaj khov
Catalyst lifespan
Tag nrho cov nqi khiav haujlwm
Cov lus qhia xaiv cov kws tshaj lij feem ntau muaj txiaj ntsig ntau dua li kev sib piv cov nqi. Yog tias koj tsis txaus siab txog kev xaivalumina ceramic pob, thov koj xav tiv tauj peb los tham txog koj qhov kev ua haujlwm tshwj xeeb. Zibo Xiangrun Environmental Engineering Co., Ltd.
