Nruab nrab Alumina Ceramic Pob rau ntim thiab sib tsoo
Nruab nrab Alumina Ceramic Pob rau ntim thiab sib tsoo
1) Spheres (pob) lossis lub tog raj kheej
2) Kev txhawb nqa zoo heev thiab npog xov xwm
3) Ua haujlwm raws li kev txhawb nqa xov xwm rau lub txaj catalyst lossis lwm lub txaj tshuaj nyob rau hauv reactors lossis yees
4) Kev ua tau zoo heev thiab ruaj khov hauv cov kua qaub thiab lwm yam tshuaj nyob ib puag ncig
5) Cov tshuaj lom neeg zoo heev thiab kev nqus dej tsawg
6) tuaj yeem tiv taus qhov kub thiab txias
7) tuaj yeem siv tau rau hauv kev pabcuam kub kub vim tias lawv tuaj yeem tiv taus ntau dua 10% sodium hydroxide kev pabcuam txog 60ºC, thiab 1% sodium hydroxide kev pabcuam kub txog 100ºC
8) tuaj yeem tiv taus cov tshuaj corrosion ntawm cov kua qaub (xws li cov organic thiab inorganic acids, tab sis tsuas yog HF acid), feem ntau ntawm alkali thiab organic hnyav
9) Yuav ua kom cov khoom xa tawm ntawm cov kua thiab roj, txhawb thiab tiv thaiv cov catalyst thiab tsis txhob muaj tshuaj lom
