Khoom Taw Qhia
Common Pseudo Boehmite (tshuaj formula AlOOH·nH₂O, n=0.08 - 0.62) yog ib qho kev hloov pauv ntawm txhuas oxide nrog rau thaj chaw tshwj xeeb thiab qhov pore loj. Nws daim ntawv ntub dej nthuav tawm lub xeev dawb colloidal, thaum nws daim ntawv qhuav yog hmoov dawb.Los ntawm cov txheej txheem kev npaj sib txawv, qhov pore ntim (0.5 - 2.0 cm³ / g) thiab thaj chaw tshwj xeeb (txog 470 m² / g) tuaj yeem tswj tau. Tom qab tau calcined ntawm 550 - 850 degree, nws ua tau -Al₂O₃ los yog -Al₂O₃.is hmoov (qhuav).Nws muaj siab crystal theem purity, zoo molding kev kawm, thiab thixotropic gel.

FAQ
1.Dab tsi yog thaj chaw tshwj xeeb thiab qhov pore ntim ntawm Common Pseudo Boehmite?"
Teb: Qhov tshwj xeeb ntawm thaj chaw ntawm cov khoom tsis tu ncua yog nyob ib ncig ntawm 300 m² / g, thiab qhov pore ntim yog 0.3 cm³ / g.
2.Pseudo Boehmite yuav ua li cas tom qab calcination? Puas yog nws tsim nyog rau kev siv los ua -Al₂O₃ cab kuj?
Answer: After calcination at 550–750℃, it mainly generates γ-Al₂O₃, which has a high specific surface area (>200 m² / g) thiab ib qho pore loj (6-15 nm), ua rau nws tsim nyog rau kev siv los ua cov cab cab hauv hydrogenation, methanation, thiab lwm yam.
3.Yuav ua li cas gelation kev ua tau zoo ntawm Common Pseudo Boehmite? Nws puas tuaj yeem siv rau extrusion molding?
Teb: Tom qab gelation, qhov viscosity tsawg dua los yog sib npaug li 200 mPa·s, nrog fluidity zoo. Nws yog dav siv nyob rau hauv extrusion molding, tshuaj tsuag granulation, thiab tshwj xeeb tshaj yog haum rau kev tsim cov denitration catalysts thiab clover - zoo li tus cab kuj.
