99% High Alumina Pob
Khoom Description
99 feem pua siab alumina npas tseem hu ua siab alumina ceramic pob packing, uas yog tib yam li Denstone®99 txhawb kev tshaj tawm. Nws cov tshuaj muaj pes tsawg leeg yog 99 ntxiv rau feem pua alpha alumina thiab mus txog 0.2wt feem pua SiO2. Vim nws cov ntsiab lus alumina siab thiab tsis tshua muaj silica (SiO2) nws yog ib qho khoom zoo heev thiab zoo tagnrho rau kev kub siab thiab chav siv. Hauv cov txheej txheem tsim khoom, cov khoom siv raw xws li high-purity tsawg lub ntiaj teb hlau oxides thiab binders tau ntxiv, thiab nws yog tsim los ntawm kev ua tib zoo batching, granulation, isostatic nias, ziab, thiab kub sintering.
Lus Cim: Cov khoom muaj pes tsawg leeg ntawm cov khoom alumina siab yog ruaj khov, tsis koom nrog cov tshuaj lom neeg, thiab tsis muaj cov tshuaj lom rau catalysts, thiab tuaj yeem tiv taus qhov kub thiab txias ntawm cov txheej txheem ntau lawm.
Super Packing Mall 99% ntshiab alumina ceramic pob muaj cov khoom siv thermal zoo heev, thiab lawv qhov ntom ntom tuaj yeem tiv taus qhov kub siab txog 1550 degree. Lawv kuj yog ib qho kev xaiv zoo rau kev txuag hluav taws xob los yog sib npaug xov xwm.
99 feem pua alumina pob ntawm Super Packing Mall muaj lub zog zoo heev, kua qaub thiab alkali tsis kam, corrosion kuj, ceev ceev txias thiab kub tsis kam, oxidation kuj, tsis tev ntawm kub, compact qauv, siab hardness, thiab nws compressive zog mus txog qib 9. thiab saum toj no.
Nws yog tsuas yog siv nyob rau hauv qhov kub thiab txias, siab siab, muaj kev cuam tshuam thiab corrosive heev nyob rau hauv kev lag luam tshuaj, xws li hydrogenation reactors, natural gas drying adsorbers, tag nrho distillate roj hydrogenation units, ammonia conversion furnaces, carbon dioxide desulfurization yees, methanol synthesis yees. , Activated carbon adsorption ntauwd, thiab lwm yam.
Tej daim ntawv thov
a) 99 Alumina Balls yog cov khoom lag luam zoo thiab tsim nyog rau kev kub siab thiab chav siv, xws li kev hloov kho theem nrab hauv kev kho ammonia, qhov twg silica leached tuaj yeem coated cov khoom siv hauv qab los yog paug cov txaj catalyst.
b) 99 feem pua Alumina Balls yog tsim rau olefin txheej txheem kev siv qhov twg polymerization yog ib qho teeb meem.
