Nyob rau hauv cov liaj teb ntawm Petrochemicals, Tshuajntsuam Tshuaj Lom, cov haujlwm ib puag ncig ntawm cov khoom siv hluav taws xob tsis muaj kev pab cuam ntawm ntau yam ntaub ntawv . ntawm lawv,Alumina Txhawb Pob, raws li ib qho tseem ceeb inert ceramic lub tshuab reactors, catalytic cov khoom siv thiab lawv lub luag haujlwm tseem ceeb hauv kev lag luam {}}
Cov yam ntxwv ntawm Alumina Txhawb Pob
• Muaj zog txhua yam: lub zog compressive feem ntau yog ntau tshaj 100 MPa, uas tuaj yeem tiv thaiv qhov kev kub siab ib puag ncig hauv lub reactor .
• Siv tau zoo heev thermal stability: nws tuaj yeem siv rau lub sijhawm ntev ntawm qhov kub thiab txias thiab haum rau cov chaw muaj zog hnyav {}}
• Tshuaj lom neeg ua haujlwm: Nws yog resorN thiab alkali corrosion (tshwj tsis yog hydrofluoric acid thiab muaj kuab lom .
• Porosity tsawg: nws tiv thaiv kev ua kom rov muaj zog ntawm reactants thiab ua kom muaj kev faib tawm ntawm cov kua .
• Cov qauv sib xws: qhov saum npoo yog du thiab txo cov kua dej tsis kam .
Tub Ntxhais ntawm Alumina Txhawb Pob
(1) Kev txhawb nqa catalyst thiab kev tiv thaiv
Hauv cov pob txaj ceev, alumina kev txhawb nqa pob yog feem ntau muab tso rau hauv qab lossis sab saum toj ntawm lub txaj catalyst {}} lawv cov haujlwm tseem ceeb muaj:
• Tiv thaiv cov catalys poob: cuam tshuam cov tshuaj ntsuab zoo kom tiv thaiv nws los ntawm txhaws cov dej ntws hauv qab {}}
• Cov kua dej khov kho: Ua kom tau zoo ntawm kev khiav ntawm cov roj lossis kua thiab kev txhim kho kev cuam tshuam .
(2) Thaum Tshav Kub Kub Hloov Thiab Kev Tswj Kub
Vim yog lub siab thermal conductivity ntawm alumina, kev txhawb nqa pob tuaj yeem siv los ua cov cua sov thiab tiv thaiv kom sov lossis kub tsis sib xws}
(3) Kev Tiv Thaiv Cov Khoom Siv
Hauv kev tsim khoom siv tshuaj lom neeg, Alumina kev txhawb nqa pob tuaj yeem cuam tshuam kev sib ceg lossis cov khib nyiab tsim thaum lub sijhawm cov tshuaj tiv thaiv thiab lwm yam khoom siv los ntawm kev hnav .

Yuav ua li cas xaiv Alumina Kev Txhawb Nqa Pob?
Hauv cov ntawv thov kev lag luam tiag tiag, cov hauv qab no yuav tsum txiav txim siab thaum xaiv cov pob alumina txhawb nqa:
• Qhov loj me me: feem ntau 2-5 zaug qhov loj me ntawm cov lus catalysts kom ntseeg tau tias kev faib cov kua kom zoo.
• Strength: High-pressure reactors need to select products with a compressive strength of >150 MPa .
• Qhov kub thiab txias: Kev ua tub rog siab -al₂o₃ txhawb nqa cov pob muaj rau qhov kub thiab txias ib puag ncig.
• Tshuaj lom neeg tshuaj lom neeg: nyob rau hauv acidic lossis alkaline ib puag ncig, cov khoom siv corrosion tiv taus ntau qib yuav tsum tau xaiv .
Txawm yogAlumina Txhawb PobTsis txhob ncaj qha koom nrog kev siv tshuaj lom neeg, lawv yog cov khoom lag luam tseem ceeb ua rau lawv muaj kev tiv thaiv thiab kev tiv thaiv ib puag ncig thiab lub zog.
